I have a project with 2 modules module-b.jar and module-a.war. The first module is a dependency for the second one which I deploy to the jetty server using the jetty:run goal of the maven jetty plugin. I configured the hot redeployment plugin feature by setting the scanIntervalSeconds configuration value to 10 seconds.
After running the server, if I modify the jar module and install it to the local maven repository, jetty will detect this change and will restart the webapp (hot redeployment). Until now, everything works as it's supposed to be. I don't have to rerun the server in order to view the new modifications. The webapp is loaded with the new modifications except when I'm accessing a part that uses the persistence mechanism which is JDO/Datanucleus, in this case I got this exception:

This can be solved by rerunning the server but that won't be interesting because I will lose the hot redeployment benefits. How can I achieve this without rerunning the server?

Can anybody tell me what could be causing this exception?. Because it is working fine in testing environment and not in the live servers .
I tried checking the differences of test and existing prod war file, but i did not find any differences.
The major change I did was converted project from ANT to MAVEN, but not sure how this is related to this exception.

I can successfully load jxbrowser in the non-OSGi environment, as well as in OSGi environment when resources are already extracted.
Is there any way to make jxbrowser successfully extracts the resources from the jar?
It is looking like you don't have a correct OSGI bundle for JxBrowser. As far as I know jxbrowser supports OSGI bundle distribution, you can simply install it into your OSGI container.
Alternatively you can create your own bundle with which is only exports JxBrowser public API, but contains JxBrowser libraries you need. You can automate it with Felix bundle plugin for example http://felix.apache.org/documentation/subprojects/apache-felix-maven-bundle-plugin-bnd.html
In order to make such a bundle working you will need to initialize an temporary browser instance (just create a browser component) inside bundle activator. So that chromium binaries will be extracted when bundle is installed in your OSGi container.
I have those problems with a webapp.Can you help me, please? :)

When I compile the file WAR, there aren't errors..

This is rather self-explaining. The mentioned class cannot be found in the runtime classpath.
Make sure that the mentioned class (or at least, the JAR file containing the class) is in the runtime classpath of the webapp. One of the folders covered by the webapp's default runtime classpath is the webapp's /WEB-INF/lib folder. Drop the necessary JARs in there.
As the package name hints, that class is part of Apache Lucene library. If you need to, you can just download it from over there.
The goal is to have an applet run from a jar file.
The problem is that the applet only seems to want to run from an exploded jar file.
Samples on the Internet suggest this applet tag:
<applet code="com.blabla.MainApplet"
archive="applet.jar"
width="600" height="600">
This will not even try to look in the jar file and fails with:
Caused by: java.io.IOException: open HTTP connection failed:http://localhost:8080/helloWord/com/blabbla/MainApplet.class

Setting the codebase instead of the archive attribute to the jar file. Looks a bit better. However, the JVM does not realize that it has to open the jar file:
<applet code="com.blabla.MainApplet"
codebase="applet.jar"
width="600" height="600">

How does the applet tag have to be formulated to start an applet class from inside of a jar file?
The problem was that the Java console was caching previous bad jars. Once the cache was cleared in the Java console, the first version of the code worked fine.
<applet code="com.blabla.MainApplet"
archive="applet.jar"
width="600" height="600">
When I try to build a project that uses Flex and where the Flex SDK is on one drive and the project files on another I get the following error in ant:
[mxmlc] java.lang.NoClassDefFoundError: flex2/tools/Compiler
[mxmlc] Exception in thread "main"
It seems to be a problem with the Flex mxmlc ant task. Anyone know the root cause of this? It works if I move the Flex SDK over to the project folder but I don't like being hackish like that...
Ant in verbose mode gives:
compile.main:

Did you put flexTasks.jar into lib folder of your ant installation?
In my case I've copied D:\Flex_sdk_3.3.0\ant\lib\flexTasks.jar into D:\apache-ant-1.7.1\lib\
I determined that this is actually a bug in the flex ant task. FlexTask.java is not doing proper pathing to work across multiple drives on a windows machine.
Somewhere there is a path that doesn't have the drive letter on the front of it. So it works when you're on the 'correct' drive, but not otherwise.
I found this blog posting - search for MXMLC= in the text - someone found a solution for a Mac install that threw the same exception. You may be able to adapt this to you situation. (It looks like maybe when the flex mxmlc compiler is installed and configured it doesn't necessarily include the drive letter everywhere its needed.)
Rather than moving or copying the jar, perhaps you can add the full path to it with drive letter as a property in your build, then append that to the classpath.
Copy Flex sdk/x.x folder to the same drive as your sources, adjust flex.sdk.home ant variable and rebuild.
