While parsing the I am getting above leaks. And NSPlaceholderMutableString responsible frame for other leaks. What is the best solution or tutorial or link to follow to get out of this leaks????
Code:
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)
namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict{
currentElementValue = [elementName copy];
if([elementName isEqualToString:@"markers"]) {

else if([elementName isEqualToString:@"marker"]) {
//Initialize the book.
aMarker = [[marker alloc] init];

But I'm struggling. I have added `akka-actor-1.1-M1.jar`, `akka-typed-actor-1.1-M1.jar`, `scala-library.jar` but it wasn't enough. I got errors in Eclipse so I also added `aspectwerkz-2.0.jar` and `aspectwerkz-core-2.0.jar` to my Build Path.
I try to use a TypedActor with custom constructor.
But now I get an error at compilation:
Exception in thread "main" java.lang.NoSuchMethodError: org.codehaus.aspectwerkz.proxy.Proxy.newInstance([Ljava/lang/Class;[Ljava/lang/Object;ZZ)Ljava/lang/Object;
at akka.actor.TypedActor$.newInstance(TypedActor.scala:596)
at akka.actor.TypedActor$.newInstance(TypedActor.scala:634)
at akka.actor.TypedActor.newInstance(TypedActor.scala)
at com.example.actor.ActorTest.main(ActorTest.java:12)
Here is my code for the `BaseActor`:
import akka.actor.TypedActor;
public class BaseActor extends TypedActor implements BaseService {
private String str;
private int num;
public BaseActor(String str, int num) {
this.str = str;
this.num = num;
System.out.println("booted");
}
public void testData(String str, int num) {
System.out.println(this.str + " " + this.num);
System.out.println(str + " " + num);
}
}
My `interface` for the service:
public interface BaseService {
public void testData(String str, int num);
}
And a test class:
import akka.actor.TypedActor;
import akka.actor.TypedActorFactory;
public class ActorTest {
public static void main(String[] args) {
BaseService service = TypedActor.newInstance(BaseService.class,
new TypedActorFactory() {
public TypedActor create() {
return new BaseActor("someString", 12);
}
});
service.testData("Hello", 6);
}
}
In the example they write:
Service service = TypedActor.newInstance(classOf[Service],
new TypedActorFactory() {
public TypedActor create() {
return new ServiceWithConstructorArgsImpl("someString", 500L));
});
But I don't think that `classOf[Service]` is Java, it's looks more like Scala.
How can I implement an `TypedActor` with a custom constructor?

After that, i tried to use the Accelerometer Sensor of my Galaxy S smartphone.I get the accelerometer values, show them in the screen. And when the values are changed(onSensorChanged method) , i send them using UDP to the application on my computer.

Right now, I am trying to trap the request within this function:
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request
navigationType:(UIWebViewNavigationType)navigationType{
NSLog(@"NSURLRequest = %@", [[request URL] absoluteString]);
}
Printing out the url as above gives me this:
http://localhost:8888/myapp://id=1234
Which is my localhost setup on MAMP with the custom URL appended to the URL.
I had hoped that I could use [request scheme] directly, but in this case now, it simply returns "http". Is there a way that I can handle custom URL schemes from within my own app?
At this point, I would like to be able to do the following:
1. User is on the webview
2. User taps the custom url link ( myapp://id=1234 )
3. My app handles the custom url and directs the user to another page ( http://www.someotherpage.com/?id=1234 )

Relative rookie here who has spent the better part of three days just trying to get started with Java EE, and it's driving me up a wall. I've already read through numerous tutorials and consulted several book, so now I am turning to you.
I am starting from complete scratch, having uninstalled NetBeans and Glassfish and the Java EE SDK. My main issue is quite simply configuration. All the resources I've found typically say in a mere throwaway line: "Once you download the SDK, you must configure your environment for Java EE." But HOW? I need it in plain English. Even the most novice guides leave this basic stuff out. Does this mean editing the JAVA_HOME path or what? How does this configuration relate to the Java SE already on my system? Furthermore, I assume I don't need to also download the JDK with EE since I already have a JDK? (I am a Mac user, if that matters.)
I know I have a long, long way to go, so I appreciate any help I can get as I try to get this ball rolling. Much thanks in advance! | java | java-ee-6 | null | null | null | null | open | Java EE -- Configuration issues for a beginner

I have created the following entities:
public class Company
{
public int CompanyID { get; set; }
public int SubdomainID { get; set; }
public virtual Subdomain Subdomain { get; set; }
}
public class Subdomain : IValidatableObject
{
public int SubdomainID { get; set; }
public virtual ICollection<SubdomainActivity> Activities { get; set; }
public IEnumerable<ValidationResult> Validate(ValidationContext validationContext)
{
int activitySum = Activities.Sum(x => x.Value);
if (activitySum != 100)
{
yield return new ValidationResult(string.Format("The Activity percentages must add up to 100. Current sum is {0}", activitySum), new[] { "Activities" });
}
}
}
public class SubdomainActivity
{
public int ActivityID { get; set; }
public int Value { get; set; }
}
Notice that a `Company` has a `Subdomain` and a `Subdomain` has an `ICollection<SubdomainActivity>`.
I have controllers for `Company` and `Subdomain`. In the `SubdomainController` when I call `UpdateModel()` (or `TryUpdateModel()`) on an instance of a `Subdomain` I get the result I want. The `Subdomain` activities are validated that the values sum up to 100.
In the `CompanyController` when I call `UpdateModel()` on an instance of a `Company` it validates that the `Subdomain.Activities` add up to 100 as well, which I don't want. The user can't even edit `Subdomain.Activites` from the `Company` edit view anyway, so it makes no sense to tell them that there was an error with `Subdomain.Activities`.
I would like to be able to add an item to the validationContext.Items IDictionary so that I can conditionally validate based on context or something like that, but I haven't been able to figure out how to do that without writing my own IModelBinder (which I could do I suppose, but seems like overkill). Ultimately I have come up with this workaround in the `CompanyController`, but I am sure there is a correct way to handle this (this is wrapped in a `try` `catch`)
var d = this.companyRepository.GetById(id);
bool good = TryUpdateModel(d);
if (!good)
{
if (ModelState.ContainsKey("Subdomain.Activities"))
ModelState.Remove("Subdomain.Activities");
if (!ModelState.IsValid)
throw new InvalidOperationException(string.Format("The model of type '{0}' could not be updated.", typeof(Company).FullName));
}
this.companyRepository.Save();
As an interesting side note, if I don't check if the model is valid and throw an error then the companyRepository.Save() works fine. In other words EFCodeFirst doesn't validate the Activities, but MVC UpdateModel goes all the way down to Activities on the Subdomain.
Can anyone help me out with a better/correct/recommended way to handle this?

In the `CompanyController` when I call `UpdateModel()` on an instance of a `Company` it validates that the `Subdomain.Activities` add up to 100 as well, which I don't want. The user can't even edit `Subdomain.Activites` from the `Company` edit view anyway, so it makes no sense to tell them that there was an error with `Subdomain.Activities`.
I would like to be able to add an item to the validationContext.Items IDictionary so that I can conditionally validate based on context or something like that, but I haven't been able to figure out how to do that without writing my own IModelBinder (which I could do I suppose, but seems like overkill). Ultimately I have come up with this workaround in the `CompanyController`, but I am sure there is a correct way to handle this (this is wrapped in a `try` `catch`)
var d = this.companyRepository.GetById(id);
bool good = TryUpdateModel(d);
if (!good)
{
if (ModelState.ContainsKey("Subdomain.Activities"))
ModelState.Remove("Subdomain.Activities");
if (!ModelState.IsValid)
throw new InvalidOperationException(string.Format("The model of type '{0}' could not be updated.", typeof(Company).FullName));
}
this.companyRepository.Save();
As an interesting side note, if I don't check if the model is valid and throw an error then the companyRepository.Save() works fine. In other words EFCodeFirst doesn't validate the Activities, but MVC UpdateModel goes all the way down to Activities on the Subdomain.
Can anyone help me out with a better/correct/recommended way to handle this?

And currently I am doing my masters (I will be out for job search after a couple of months). However, since I have only two years of experience, I was planning to apply for junior positions (either as java developer or a java web developer) . But, after I saw [this][1] question, I was amazed that the questions are very easy (of course I will be able to explain each of them very well) and every developer should have to understand them. Do you think only such kind of questions appear for a 2 year junior developer?
Since I am studying with senior developers and few project managers (most of them has 3-7 years of experience), I saw myself that I can do almost an equal job like them, except with some exceptional students. I am not exaggerating things, but expressing what I have seen so far.
Does anyone have a good interview question that might be asked to a java web developer who has experience like me? If it is not going to be hard, I have a plan to apply for mid level jobs. By the way while you guys give me your suggestion I am also googling, not sitting down and wait for your answers.

}
}
})
})(jQuery);
Now this worked fine in the small test file where I originally called it (the code did what I wanted it to) but after execution I got the following error:
DOM Exception:
**INVALID_CHARACTER_ERR (5)**
I ignored it, not being sure where it was coming from nor how to fix it (the few references I found on the web associated the problem with IE9 which I was not using) but when I used my new code site-wide everything started breaking with error messages such as
**Uncaught TypeError: undefined is not a function**
and
**Uncaught TypeError: Object function (c, d) { // newmethod code }**
Any ideas as to what I'm doing wrong are welcome

The admin of each organization is allowed to create custom fields for business concepts.
Example: Patient of org X has attribute A and B while Patient of org Y has attribute M and N
After doing research, I find that there're a few considerable design approaches:
**Option 1**: have a BusinessObjectCustomField for each business table. Example for PatientCustomField
OrgID, CustomFieldID, Value
X, A, 1
X, B, 2
Y, M, 3
Y, N, 4
**Option 2**: use a single table for each business object, but alter table when new custom field is added. As a result, num(column) ~ num(org) * num(average fields per org)
PatientID A B M N
1 1 2 NULL NULL
2 NULL NULL 3 4
**Option 3**: use generic purpose columns to hold data. As a result, num(column) ~ max(fields per org)
PatientID Col1 Col2
1 1 2
2 3 4
**Option 4**: store custom data as XML
PatientID CustomField
1 <custom><A>1</A><B>2</B></custom>
2 <custom><M>3</M><N>4</N></custom>
My design priorities are:
1. Good performance
2. Easy to code
3. Space (since data will be a lot)
Which option should I choose? I know that MS SQL Server supports index for XML data, but does it provide equally good performance as relational indexing?

Which option should I choose? I know that MS SQL Server supports index for XML data, but does it provide equally good performance as relational indexing?

At the moment, the filter chain is built as the classes are loaded. I have a very particular need for the filter chain to be rebuilt at some point in time after the classes have loaded.
This is to do with a Rails project (Spree, Radiant may also be affected I'm guessing) that uses extensions which can do things like this **after** the filter chain has been built for MyController:
MyController.class_eval do
before_filter :my_filter_method
end
ApplicationController.class_eval do
before_filter :app_filter_method
end
The problem here is that the `app_filter_method` filter will **not** be added to the MyController filter chain. This is because the filter chain of MyController is built from an earlier copy of the filter chain of ApplicationController. This copy of the filter chain of ApplicationController does **not** yet have the `app_filter_method` filter applied to it.
I can think of 2 places so far that the rebuilding of the FilterChain could happen in:
1) Each time it is called on MyController.filter_chain
2) Reloadable on demand. So MyController.reload_filter_chain will rebuild the filter chain, using the filters from MyController's subclasses in the chain.
I have had a look but haven't come up with a way to do this.
Here are links to the source of filters.rb on GitHub, for Ruby on Rails 2.3.2:
[The filter_chain method (line 573)][1]
[The FilterChain class (line 10)][2]
I was hoping some of you here might have some insight or advice on how to do this.
Any help much appreciated.

[The FilterChain class (line 10)][2]
I was hoping some of you here might have some insight or advice on how to do this.
Any help much appreciated.

I would like to execute some Javascript after the document has loaded and even after the document.onload functions have been executed.
Situation:
I'm loading a text-edit field through ajax. When the user submits the form, he is redirected to a PHP file. That PHP file redirects him back to "file.php" using header('location: file.php');
What I want to do is to execute some Javascript actions in file.php, but when I print the <script></script> tags the file id displayed blank - nothing is loaded at all. As soon as I leave them out, the page does get loaded.
Any suggestions? | 1 |

Theoritically all traffic that originates from every computer has to go through an ISP, a bunch of intermediate routers and finally reach it's destination host. So if the ISPs monitor incoming and outgoing addresses they should be able to tell which IP addresses is making all these connections to a large number of destinations or some such heuristic...
In general these backbone providers and ISPS together essentially know where the connections from each computer go, so why not follow them ?

Public Function isitnullorempty(newstring As String) As Boolean
If IsNull(newstring) Or IsEmpty(newstring) Or newstring = "" Then
isitnullorempty = False
Else
isitnullorempty = True
End If
End Function
It seems to work as expected if I create a variable and then set it to null, "", or leaving it empty. I manipulate the variable and then do MSGBOX isitnullorempty(variable) and it echos what I expect. It doesn't behave the same way when I put a recordset inside the function however. I've even tried to make a variable set it to the record set and then test it but that doesn't work either. If I try to invoke the following
'ADO query code here (This is an ODBC connection)
DO While (Not oRecordset.EOF)
MsgBox isitnullorempty(oRecordset.Fields("CustomerTypeRefFullName"))
oRecordset.MoveNext
Loop
This yields the error: Invalid use of Null.
So two fold question.
Is there already a vb function that exists which does what I want?
Why does my code behave this way?
Weirder yet is that if I do the test individually outside of the function, it works. | function | vba | error-message | null | null | null | open | VB using a ADO Recordset inside a vb function, checking for null

It does the job but does not look very clean to me. Is there some way I could make this code a bit smaller.

My navigation bar, after being redone 3 times, still didn't give me the result I was looking for. I copied some code and plopped a placeholder in there for now, but I'd like to get a pointer as to how I can achieve the look I'm shooting for.
