Hi!
I have a problem when using my jaxb-generated classes within a servlet.
I put my jaxb-generated classes (jar-file) and the jaxb-jars in
"webapps/my-app/WEB-INF/lib". When the servlet is running, I get a
ClassNotFoundException:
java.lang.ClassNotFoundException: com.sun.xml.bind.ContextFactory_1_0_1
at java.net.URLClassLoader$1.run(URLClassLoader.java:199)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(URLClassLoader.java:187)
at java.lang.ClassLoader.loadClass(ClassLoader.java:289)
at java.net.FactoryURLClassLoader.loadClass(URLClassLoader.java:575)
at java.lang.ClassLoader.loadClass(ClassLoader.java:235)
at javax.xml.bind.ContextFinder.newInstance(ContextFinder.java:72)
at javax.xml.bind.ContextFinder.searchcontextPath(ContextFinder.java:229)
at javax.xml.bind.ContextFinder.find(ContextFinder.java:149)
at javax.xml.bind.JAXBContext.newInstance(JAXBContext.java:281)
Then I put the jaxb-jars in %TOMCAT_HOME%/common/endorsed. Now the
classes are found but I get the following exception:
ava.lang.ClassCastException
at ebsa.TableOfPoliciesFactory.unmarshall(Unknown Source)
When I put the jar-file with my jaxb-generated classes in the endorsed
directory, too, I get some other exception, but however this is no
solution since I want to deploy the classes as a webapplication.
I create the JAXBContext with an URLClassLoader and that seems to be the
problem:
URLClassLoader urlClassLoader = URLClassLoader.newInstance(urls);
ctx = JAXBContext.newInstance(packageList, urlClassLoader);
In an other servlet I create the JAXBContext without specifying a
classloader - ctx = JAXBContext.newInstance(packageList) - and it works.
As a standalone application, my application with creating the
JAXBContext using an URLClassLoader also works fine.
Has anybody some ideas how I can instantiate the JAXBContext with an
URLClassLoader within a servlet?
Thanks!
Thomas
