Getting "java.lang.ClassNotFoundException" while creating JAXBContext instance

[sivaram123]

Hi I have an osgi bundle which uses JAXB api for marshalling and unmarshalling xml data. While creating the JAXBContext instance i am getting the java.lang.ClassNotFoundException: javax.xml.bind.JAXBContext. These jaxb classes are provided by default in the jdk 1.6.

I have added the following capability in the standalone.xml osgi subsystem:

<capability name="javax.xml.bind.api" startlevel="1"/>

But again getting the same exception. Do I need to add extra configuration to access these classes. I am using jboss-as-7.1.1.Final.

Please help me to resolve this issue.

Thanks in advance.

Hi Thomas,

Thank You for the response. Is there any other way to access these jaxb libraries at the moment.

Hi Thomas,

I have checked the issue here https://issues.jboss.org/browse/AS7-5531 as it is in the resolved status. I have downloaded the jboss 7.2.0.Alpha1 and getting the following errors while creating the JAXBContext:

In my application i need to create the jaxb context object in the stating phase of the bundle(In Activators start method).  I am getting the above exception. Is this issue is resolved in the new version ?.

Kindly please guide me as i need it urgently for my application. I am attaching the bundle  and the source code that i am testing.

Regards,

Siva Ram.

This might be the root cause

jboss-modules provides these JAXP redirects. It is possible that the module that loads javax.xml.datatype.DatatypeFactory does not have a wire to org.jboss.modules

It is also possible that there is some invalid TCCL involved in the discovery.

Gernerally, many of these JRE APIs use the TCCL for discovery of their respective implementations, which is obviously not going to work in an OSGi environment.

There is a variant

JAXBContext.newInstance(String contextPath, ClassLoader classLoader)

that takes an explicit CL. Maybe that would help if this is related to some TCCL issue.

If you look at the test case, this is how I do it

JAXBContext jaxbContext = JAXBContext.newInstance(ObjectFactory.class.getPackage().getName(), ObjectFactory.class.getClassLoader());

HI Thomas,

I have tried in that way also by creating jaxb context using package name and class loader. Getting the same above error response don't know how to resolve this error.

Added the below line in the code getting the same exception above:

JAXBContext jcontext = JAXBContext.newInstance(Bookstore.class.getPackage().getName(), Bookstore.class.getClassLoader());

Kindly help me resolving this issue. Is it a problem in my code. Do i need to add any extra configurations.

Kind Regards,

Siva Ram.

[thomas.diesler]

In that case we need to step back a little and work on a test case that allows us to repoduce the issue. Could you perhaps provide a patch to the existing jaxb test case or a variant of it?

[sivaram123]

Hi Thomas,

Here i am attacing the bundle and the eclipse project source code for the sample bundle. By deploying the bundle in the server we can see the error we are getting.

Kindly find the attached files.
