I tried above in glassfish works fine , i know its jboss...
I found another relevant post here
java.lang.ClassNotFoundException: org.jboss.logging.Logger
grep for;
When I added the jbossall-client.jar from tje jboss installtion path(../jboss-5.1.0.GA\client) and not from the lib folder, it worked.
that could be your answer.....

Trying to run scala swing and getting Exception in thread "main" java.lang.NoClassDefFoundError: scala/swing/MainFrame

Here is my code I am trying to run:
import scala.swing._
object MyApp extends SimpleSwingApplication{
def top = new MainFrame{
contents = new Label("GUI stuff")
}
}
I am running the code through command line. In my directory, I have the code above (app2.scala), a scala swing jar file (scala-swing_2.13-2.1.1.jar).
I am compiling the scala file like:
scalac -cp "scala-swing_2.13-2.1.1.jar" app2.scala
then trying to run it through
scala MyApp
But I get an error:

How can I fix this?
I checked that my scala version is the same as the version for swing. I am running 2.13.2

install4j service start exception

I created an new application iteration using install4j v5.1.15.
The application starts a windows service after installation which has couple of steps to try and hit few URLs to get the updates or make sure some other configuration is available.
All I am getting is this below exception after installation is complete(used debugger mode). Is there any way I can configure the installer to give out more information(either point out which URL it is accessing), I have made sure that the all URLs added as present in the .install4j file are available.
What else can I try?

Providing an update as the root cause was found to be unrelated to the install4j tool.
The jar I was using for packaging the installable was invalid. We had recently updated the maven plugin versions. The newer version changed the way our jar was packaged, which did not allow the service to start post the installation.
I am still receiving the same error as listed in the initial post, not sure of the source (I am ignoring that one for now).

trying to read the rules using the changeset.xml from guvnor results in error

I tried to load the package from the Guvnor using the following piece of code :-

KnowledgeBuilderErrors errors = kbuilder.getErrors();

throw new IllegalArgumentException("Could not parse knowledge.");
}

kbase.addKnowledgePackages(kbuilder.getKnowledgePackages());
return kbase;

Preconditions :-
I use Guvnor 5.3 with jboss AS 7.0.
Both the client and the server are sharing the same jre7.
Drools runtime 5.3 in Eclipse Indigo (Service Release 2)
Requesting for a workaround ...
Drools related jars used in java project are NOT of same version as used in GUvnor 5.3.
Use jars from Guvnor 5.3 into your java project.
It will solve problem. :)

Changing labels in a JFace TreeViewer on node expansion/collapse

I have a TreeViewer where some nodes represent folders, so I wanted to show the icon of an open folder when the node is expanded and a closed folder when it is collapsed. Sounds easy, I just need to add a tree listener (the code is in Scala, but Java equivalent should be easy to imagine):
val tree = new TreeViewer(contents)
tree.addTreeListener(folderIconFixingListener)
private def folderIconFixingListener = new ITreeViewerListener {
def treeCollapsed(event: TreeExpansionEvent) {
tree.update(event.getElement, null)
}
def treeExpanded(event: TreeExpansionEvent) {
tree.update(event.getElement, null)
}
}
Unfortunately, this gives an exception:
Ignored reentrant call while viewer is busy. This is only logged once per viewer instance, but similar calls will still be ignored.

How can I fix this?
You might try to put your code in your listener into a asyncExec, to postpone its execution a bit:
display.asyncExec(new Runnable(){
public void run(){
tree.update(.);
}
});
The solution I eventually went with was to use a TreeListener on the Tree control itself instead, which worked fine.

How can I use JAXB from an unsigned applet (without signing it)?

I would like to marshall Java objects into XML and vice-versa from within an Unsigned Applet and I can't change any of the security permission/policy files, or sign the application.
I seem to get a Security exception, because JAXB is attempting to access fields or constructors that it can't in the applet sandbox.
The browser is running JRE 1.6.0_17
I'm also open to solutions based on some other XML (or JSON) library but have tried the following and pretty much run into a similar problem;
- XStream
- Gson
Given (something like) the following object:
#XmlType
#XmlRootElement
public class SimpleObject {
public String sampleText;
public SimpleObject() {
}
public String getSampleText() {
return sampleText;
}
public void setSampleText(String sampleText) {
this.sampleText = sampleText;
}
}
And the following simple JAXB code:
public void actionPerformed(ActionEvent e) {
try {
JAXBContext jc = JAXBContext.newInstance(SimpleObject.class);
Marshaller marshaller = jc.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
SimpleObject object = new SimpleObject();
object.setSampleText("Hello");
marshaller.marshal(object, System.out);
}
catch (JAXBException e1) {
throw new RuntimeException(e1);
}
}
I get the following exception:

I never did quite figure this one out. What I did instead was to grab a fairly simple JSON library called Flexjson. It also threw a similar security exception but the library was simple enough that I was able to switch-off the library code that causes the exception in an Applet with a boolean flag.
I also tried to find a solution with JAXB without any success.
I switched to Axis2 (1.5.4) with ADB binding, but it also tried accessing system properties which failed with security manager checks.
In the end, I got a workable solution together by using AspectJ and using an aspect that rewrites System.getProperty() calls to return null when they fail. Since all the properties Axis2 needed were non-critical anyway this worked. I also needed to apply an aspect over org.apache.axiom.util.stax.dialect.StAXDialectDetector.getRootUrlForResource() to always return null since it tried to make a ClassLoader.getSystemClassLoader() call which also failed under a security manager. Again this seemed like a non-critical call. Got AspectJ to rewrite the Axis2 classes at build-time and it ran as an unsigned applet.
It's a really messy solution, but at least it worked.
I couldn't get the same AspectJ hack working with JAXB because JAXB requires direct access to the private fields of classes which doesn't fly under a security manager if JAXB is bundled with the applet (which we need to do if AspectJ is used to rewrite classes).
This may solve your problem. I know it solved mine :)
public void actionPerformed(ActionEvent e) {
try {
JAXBContext jc = AccessController.doPrivileged(new PrivilegedExceptionAction<JAXBContext>() {
public JAXBContext run() throws JAXBException {
// needs to run here otherwise throws AccessControlException
return JAXBContext.newInstance(SimpleObject.class);
}
});
Marshaller marshaller = jc.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
SimpleObject object = new SimpleObject();
object.setSampleText("Hello");
marshaller.marshal(object, System.out);
}
catch (JAXBException e1) {
throw new RuntimeException(e1);
}
} catch (PrivilegedActionException e2) {
throw new RuntimeException(e2);
}
}
Hope it helps
