I have deleted the earlier class and .ear-files, cleaned the workspace, compiled the code with JavaSE 1.6, set the system library to 1.6 then compiled and created the .ear. I am getting this error when I have installed the ear on server and try to open with url:

This error happens when your VM has another version (a lesser version) than the compiled class files.
Could it be that your server still run with java 1.5?

Current jetty version is 9.4.6, I tried to upgrade 9.4.44, I got the error. Could you please help me?

I had a different setup that triggered a similar stacktrace: using cargo-maven2-plugin 16.1 in a spring 5 project, mvn cargo:run would fail because of a conflict with javafx.base-11.0.0-SNAPSHOT.jar files.
Upgrading to cargo-maven3-plugin 1.9.9 fixed the matter.
I'd encourage who ever uses cargo-maven2-plugin to migrate to cargo-maven3-plugin as the doc states:
Please be aware that the Maven 2 / Maven 3 plugin of Codehaus Cargo has been retired with our version 1.9.0 and has been superseded by a Maven 3 only plugin.
I am getting error while trying to build a java project in TeamCity. The same project builds and excecutes well on my local. I recently pushed changes to this project on GitLab. This is my first time working with GitLab and TeamCity together. Other projects have no issues during build. I am unable to understand what is causing this error:

com.bea.util.jam.internal.javadoc.JavadocClassloadingException: An error
has occurred while invoking javadoc to inspect your source
files. This may be due to the fact that $JAVA_HOME/lib/tools.jar does
not seem to be in your system classloader. One common case in which
this happens is when using the 'ant' tool, which uses a special
context classloader to load classes from tools.jar.
This situation elicits what is believed to a javadoc bug in the initial
release of JDK 1.6. Javadoc attempts to use its own context classloader
tools.jar but ignores one that may have already been set, which leads
to some classes being loaded into two different classloaders. The
telltale sign of this problem is a javadoc error message saying that
'languageVersion() must return LanguageVersion - you might see this
message in your process' output.
This will hopefully be fixed in a later release of JDK 1.6; if a new
version of 1.6 has become available, you might be able to solve this
by simply upgrading to the latest JDK.
Alternatively, you can work around it by simply including
$JAVA_HOME/lib/tools.jar in the java -classpath
parameter. If you are running ant, you will need to modify the standard
ant script to include tools.jar in the -classpath.

I found there was character encoding issue with one of the files that prevented compiler from loading the java classes. Once that was fixed, the build worked fine.

I have jaxb-api.jar, jaxb-impl.jar and jaxb-xjc.jar getting loaded from code but not from JBoss default modules as they are getting used in my code.
Any pointer for the possible cause of this exception?
Regards,
I had two folder with same name in different case and hence the issue.
My EAR had folder structure like:
com.bp.gp.addfilters and com.bp.gp.addFilters.
Looks like, JBoss uses underlying OS's search method to look for folder.
Linux search is case sensitive by default, hence it never gave this error.
Since windows search is case insensitive by default, it was always trying to search inside com.bp.gp.addFilters package whereas the class was present in com.bp.gp.addfilters package.
I am new in jetty. I am trying to run Jetty with IKVM. However, it throws exception. I am not sure what should I do.

It seems that I need to install some external libraries in order to make it works. But what should I need to install.
The environment is fresh and clean:
Ubuntu 11.04
IKVM 0.40.0.1
Java 1.6.0_22
Mono 2.6.7
Update on 28 June 2010
I think I make it works. But I haven't try loading .NET classes in jetty. By the way, I used a dirty method that I replaced /usr/bin/java and /usr/lib/jvm/default-jvm/java with ikvm.exe. So everytime when I type java that actually is IKVM.
I will try to load .NET classes in jetty. But I am not familiar with jetty so I may take sometime.
Update on 1 July 2010
I have tried to load a .NET class. However, finally I got an error message.

Can you run Jetty with 'java -jar start.jar'?
I suspect you need at least a few base JAR files for jetty even if it's classloader dynamically loads everything that is needed. It looks like it is failing in the log initialization.
Add the xerces JAR file to the classpath when running IKVM.
ikvm -cp .:xerces.jar -jar startup.jar
Update
I just looked through jetty.sh and there are a few things the script file sets up. You'll need to go through that file and determine what you need out of it, or replace all the instances of java with ikvm and be aware that Jetty also uses tools.jar
The jar files that you generate with ikvmstub are only for the java compiler and not for the runtime. The java compiler can nor work with .NET dlls. For the runtime you need to use the dlls directly.
We use the jetty without problems with IKVM but we use a newer version 0.46. The simplest is you build all jar files in one step with a shared classloader. See the ikvm wiki for details.

That means you're using a Java version 5 compiler, but some of your class files have been compiled with Java 6. To work with Java 6 class files, you must use a Java 6 compiler. You probably have both installed on your machine, but either 1.5 is first on your PATH, or Maven is configured to use it.
