I'm having some annoying classpath problems trying to do something relatively simple, just running the "xjc" task from a small Ant build script.
I'm using JDK 1.5 and Ant 1.7.1. I'm seeing the following exception when I try to run xjc: java.lang.NoClassDefFoundError: com/sun/xml/bind/v2/runtime/JAXBContextImpl$JAXBContextBuilder I think some of the elements that are involved here are: * Ant has its own jaxb/xjc classes in "ant.jar" * There appear to be multiple jar sets of "jaxb 2", and I don't know which one is which A couple days ago I had to write a build script to do just about the same thing, generating a client jar from a schema. I thought I had the latest jaxb jars in the project lib dir. This had no trouble at all. It generated the client jar with no errors. Then, I started work on the client jar build on the other project, which at the time was using at least a different copy of the jaxb jars. That hit the NCDFE shown above. After I went back and looked at the first project that worked fine, I discovered I had accidentally specified the wrong path to the "xjc" jar in my lib directory, so that reference wasn't finding anything. When I changed the reference to match the file name, that original project then started getting the same NCDFE. I then turned on verbose class loading in ANT_OPTS, which told me that Ant had its own versions of the jaxb/xjc classes. I don't know whether they're "wrong", just "different". I suppose it's possible they're the JAXB "1" classes, but I don't know. I also tried adding the Ant "-verbose" command line arg. This gave me some useful info when it tried to run "xjc". When I can get "xjc" to work, I see the following in the build output: build id of XJC is hudson-jaxb-ri-2.1-257 When I get the NCDFE, I get this: build id of XJC is hudson-jaxb-ri-2.1-833 I then tried running Ant with a "-lib" command line argument, specifying the path to the jaxb jars that I'm TRYING to use. I did this in both projects. This worked, in both projects. Unfortunately, this isn't really a reasonable workaround for me. What can I do to get this to just work, without any serious hacks? --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@ant.apache.org For additional commands, e-mail: user-h...@ant.apache.org
