I asked this question on the bsf-user mailing list but it doesnt seem to be very active. The bsf-user archieve at http://mail-archives.eu.apache.org/mod_mbox/jakarta-bsf-usr/ is also not available. I'm working on an opensource project http://code.google.com/p/wulumuqi/ that integrates BSF. Any help getting BSF to use URLClassLoaders will be much appreciated.

The following code does not seem to work: package net.omnivention.bsf; import java.net.URL; import java.net.URLClassLoader; import org.apache.bsf.BSFManager; import org.python.core.PySystemState; public class WuluClassLoaderTest { public static void main(String[] args) throws Exception { BSFManager.registerScriptingEngine("ruby", "org.jruby.javasupport.bsf.JRubyEngine", new String[] { "rb" }); BSFManager manager = new BSFManager(); manager.loadScriptingEngine("ruby"); manager.loadScriptingEngine("jython"); URLClassLoader clzLoader = new URLClassLoader(new URL[]{ new URL("http://linuxjedi.omnivention.net/~son/";) }); Class<?> clz = clzLoader.loadClass("cn.com.blackdragonmedia.Address"); System.out.println("clz="+clz); manager.setClassLoader(clzLoader); System.out.println(manager.getClassLoader()); PySystemState.add_package("cn.com.blackdragonmedia"); manager.exec("jython", "abc", 0, 0, "from cn.com.blackdragonmedia import Address"); manager.exec("ruby", "abc", 0, 0, "include_class cn.com.blackdragonmedia.Address'"); } } URLClassLoader is loading the class when using clzLoader.loadClass("cn.com.blackdragonmedia.Address") but not when I run the python script and ruby script to import the class for python, I get Exception in thread "main" org.apache.bsf.BSFException: exception from Jython: Traceback (innermost last): File "<string>", line 1, in ? ImportError: cannot import name Address at org.apache.bsf.engines.jython.JythonEngine.exec(JythonEngine.java:146) at org.apache.bsf.BSFManager$6.run(BSFManager.java:493) at java.security.AccessController.doPrivileged(Native Method) at org.apache.bsf.BSFManager.exec(BSFManager.java:491) at net.omnivention.bsf.WuluClassLoaderTest.main(WuluClassLoaderTest.java:24) for ruby, I get Exception in thread "main" org.apache.bsf.BSFException: Exception at org.jruby.javasupport.bsf.JRubyEngine.exec(JRubyEngine.java:110) at org.apache.bsf.BSFManager$6.run(BSFManager.java:493) at java.security.AccessController.doPrivileged(Native Method) at org.apache.bsf.BSFManager.exec(BSFManager.java:491) at net.omnivention.bsf.WuluClassLoaderTest.main(WuluClassLoaderTest.java:25) Any idea how to BSF to use URLClassLoader? --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
