Re: Possible memory leak in Wicket 1.5.12
Hi,
It would be quite hard to reproduce the problem in quickstart application.
Here is the code of DynamicImageResource:
@Override
protected byte[] getImageData(IResource.Attributes attributes) {
try {
return IOUtils.toByteArray(stream);
} catch (IOException ex) {
LOG.error(Could not return byte[] from + stream, ex);
return null;
} finally {
if(stream != null){
try {
stream.close();
} catch (IOException ex) {
LOG.error(Could not close stream, ex);
}
}
}
}
And then I use the NonCachingImage in conjunction with my
DynamicImageResource implementation class.

Re: Possible memory leak in Wicket 1.5.12
Yeah, sure. Here is the code:
public class LocalFileResource extends DynamicImageResource {
private final Logger LOG = Logger.getLogger(LocalFileResource.class);
private String filePath;
private InputStream stream;
public LocalFileResource(String filePath) throws FileNotFoundException {
this.filePath = filePath;
File file = new File(filePath);
if(!file.exists()){
throw new FileNotFoundException(Could not load file +
filePath);
}
try {
stream = new FileInputStream(file);
} catch (FileNotFoundException ex) {
throw new FileNotFoundException(Could not obtain stream from
+ filePath);
}
}
public LocalFileResource(InputStream stream) {
if(stream == null){
throw new IllegalArgumentException(Stream cannot be null);
}
this.stream = stream;
}
@Override
protected byte[] getImageData(IResource.Attributes attributes) {
try {
return IOUtils.toByteArray(stream);
} catch (IOException ex) {
LOG.error(Could not return byte[] from + stream);
return null;
} finally {
if(stream != null){
try {
stream.close();
} catch (IOException ex) {
LOG.error(Could not close stream: + ex.getMessage());
}
}
}
}
}

Re: Possible memory leak in Wicket 1.5.12
Hi, It's used very rarely so it should not be a problem. However I've moved the stream creation from the constructor to getImageData method. The important point here - it only happens when the crawler visits my website. When normal users visit my website the file descriptors are closed successfully. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Possible-memory-leak-in-Wicket-1-5-12-tp4668856p4668868.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Possible memory leak in Wicket 1.5.12
Actually I've checked the code in the second constructor and the stream is the ByteArrayInputStream instance. But I've moved the stream creation from the first constructor to the getImageData because that's the constructor I use to create the 99% of the images in my website. And yes I've changed it today. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Possible-memory-leak-in-Wicket-1-5-12-tp4668856p4668870.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Possible memory leak in Wicket 1.5.12
Hello, I've developed an Wicket website in Wicket 1.5.12. It's hosted on Glassfish server 3.1.2.2 and lately I've run into the following problem: The problem only occurs when a crawler (for example googlebot) visits my website and then when it's crawling, Glassfish opens a lot of file descriptors (for images) and doesn't close it. This leads to Too many open files exception and right after that my server crashes. Those file descriptors are open all the time - I've to restart the server to delete the file descriptors. So I wanted to ask if it's possible that it's a wicket related problem or it's just Glassfish problem ? Thank you for any help. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Possible-memory-leak-in-Wicket-1-5-12-tp4668856.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Load Image in IE fails

Wicket Form + multiple fields
Hello, Im struggling with a strange behaviour. Introduction: 1. I want to show user his products in a cart. So each row contains product name + textfield with quantity. 2. He can set the quantity to other value. Some products have maximum number per transaction. So I've added validators the textfields. 3. Im using PropertyModel(myObject, quantityProperty) for each Textfield. 4. Now when user clicks on checkout button and lets say I have two products - one product passes the validation, the second doesn't the values of both fields are restored to default. I don't get this behaviour because when product passes the validation his model should be updated with new value but it doesn't. Any idea how could I change this ?

Re: Wicket 1.5.8 + EJB 3.1 - strange problem
Unfortunately even after changing the version of the wicketstuff-javaee-inject to newer version the problem still exists. What's more interesing is that when I navigate over the page (everything except back button) the @Stateful bean works. Only back button click recreates the @Stateful bean (but... after the bean has been recreated, when I click on a links etc, container returns me correct bean instance (previous bean - before recreation)). I wonder if you know someone from the wicketstuff-javaee-inject, so maybe they could provide me a workaround or smth ?

Re: Wicket 1.5.8 + EJB 3.1 - strange problem
Nope. Look at the example: 1. User has chose to add a product to the Cart (so now the cart number is 1 and he can see that number in a proper place on the page). 2. Now when he clicks back button - bean is recreated - so the cart number is 0 (list is recreated). 3. BUT now when I click on any other link on my page container returns previous EJB bean so the cart number is 1. Btw Im using LoadableDetachableModel so there is no way that the user is seeing stale data.

Wicket 1.5.8 + EJB 3.1 - strange problem

But now, it's the time that I need to introduce @Stateful bean into the application. And because of that I'm struggling with a very strange problem.

Re: POST parameters lost during InterceptException
The point is that I cannot catch the exception. The code enters first if in
the catch section:
if (e.getTargetException() instanceof ReplaceHandlerException ||
e.getTargetException() instanceof AuthorizationException ||
e.getTargetException() instanceof WicketRuntimeException)
{
throw (RuntimeException)e.getTargetException();
}
It's ReplaceHandlerException and during the debugg session there is no
message, cause or stacktrace in the exception object. But the exception's
target status is 302. So it's some kind of error code or something but it
doesnt say anything about the exception.

POST parameters in URL Problem
Hello, I'm facing really strange behaviour in my wicket web application. I have two websites: 1. The first website at some point must send post data to another wicket website. The form code that's gonna transport post data: String form = form id='redirectForm' method='post' action=' + redirectTo + '; form += input type='hidden' name='transactionId' value=' + transactionId + '/; form += /form; form += ; 2.The second website lets say is working under http://localhost:8080/app/home Nothing fancy. Just a Post method and a hidden field with value. Everything works like a charm except that after the redirect is done I can see the parameter that was send by post method. The result looks like: http://localhost:8080/app/home?transactionId=1231231231 I use Apache Wicket 1.5 and to map requests to url's I use: new AnnotatedMountScanner().scanPackage(package.website).mount(this); Then on every web page I use annotations like: @MountPath(value = home) The HomePage has constructor with PageParameters.
