I want to create a simple web service in Eclipse (Helios J2EE), using Apache CXF 2.3.2 and Tomcat 7.
However, when I use the ‘New web service’ wizard, I get the following error at WSDL creation:

java.lang.LinkageError: JAXB 2.1 API is being loaded from the bootstrap classloader, but this RI (from jar:file:/C:/Users/me/apache-cxf-2.3.2/lib/jaxb-impl-2.2.1.1.jar!/com/sun/xml/bind/v2/model/impl/ModelBuilder.class) needs 2.2 API.

I found some posts suggesting to copy jaxb-api-2.2.1.jar in %JAVA_HOME%/lib/endorsed, but that doesn’t work for me…

Any idea? Thanks

    Ok, some information may help you solve this problem by your own:

    java.lang.LinkageError: JAXB 2.1 API is being loaded from the bootstrap classloader, but this RI (from jar:file:/C:/Users/me/apache-cxf-2.3.2/lib/jaxb-impl-2.2.1.1.jar!/com/sun/xml/bind/v2/model/impl/ModelBuilder.class) needs 2.2 API. Use the endorsed directory mechanism to place jaxb-api.jar in the bootstrap classloader. (See http://java.sun.com/j2se/1.6.0/docs/guide/standards/)

    1. Do you know what is the bootstrap classloader? Its a “super” class loader. If you put a JAR in this classloader you can overwrite even java.lang.* classes. It’s the first class loader in any Java application. It’s a powerfull thing.

    2. Let’s take a look in your message:

      JAXB 2.1 API is being loaded from the bootstrap classloader, but this RI ([…]) needs 2.2 API […].

      You just need to replace the version of your JAXB API, right? So, check what is on your bootstrap class loader (try print all JAVA_* variables and Java start line to find your bootstrap) and find what is wrong. Probably some JAR has the old version of JAXB and need to be replaced. Only that.
