"JBREFLECT-5 - Implementing generics in JavassistClassInfo" To view the discussion, visit: http://community.jboss.org/message/539766#539766 -------------------------------------------------------------- 2 - classloader for parameterized type I posted this last night right after my "1 - other problem", but could not see it again today?!? Anyway, for a test still using SomeSignature and SomeValue, but now uses the lazy feature where I do something along the lines of public void testClasses() throws Throwable { generateClasses(); ClassInfo info = (Classinfo)getTypeInfoFactory().getTypeInfo(SomeSignature.class); MethodInfo mi = info.getDeclaredMethod("signature", new TypeInfo[0]); ClassInfo returnInfo = mi.getReturnType(); //Constructs the parameterized class info internally TypeInfo[] args = returnInfo.getActualTypeArguments(); //* Lazily loads the type arguments } This fails with the call to returnInfo.getActualTypeArguments() java.lang.IllegalStateException: java.lang.ClassNotFoundException: org.jboss.test.classinfo.test.JavassistParameterizedClassInfoClassLoaderArgumentsTestCaseWithSignature at org.jboss.reflect.plugins.javassist.JavassistTypeInfoFactoryImpl.getTypeInfo(JavassistTypeInfoFactoryImpl.java:840) at org.jboss.reflect.plugins.javassist.JavassistTypeInfoFactoryImpl.createTypeInfoForTypeArgument(JavassistTypeInfoFactoryImpl.java:898) at org.jboss.reflect.plugins.javassist.JavassistParameterizedClassInfo.getActualTypeArguments(JavassistParameterizedClassInfo.java:115) ....

One way around this would be in mi.getReturnType() when looking up/creating/caching the parameterized class info to use the classloader of mi.getDeclaringClass().getClassLoader(), which should be able to see all the classes involved. However, I am still stuck on which classloader to use for my previous post. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/539766#539766] Start a new discussion in JBoss Microcontainer Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2115]
