Lewis Ship Reporter: Yuxiang Bu Created: Mon, 13 Sep 2004 2:24 AM Updated: Mon, 13 Sep 2004 2:24 AM Description: Request for adding build-in support for Hibernate Session and Transaction management in HiveMind lib. Since Hibernate is so popular now, I believe it will become a hot request. At first I try to develop an HibernateInterceptorFactory service using javassist. But I found javassist cannot support "finally" yet. And the target code like this: boolean isTransactionBegunInThisMethod = false; try { isTransactionBegunInThisMethod = tm.beginTransaction(); Object result = _inner.... if (isTransactionBegunInThisMethod) tm.commitTransaction(); return result; } finally { if (isTransactionBegunInThisMethod) tm.rollbackTransaction(); } And I cannot develop similar codes in javassist. Then I developed an Interceptor with JDK proxy. However, the interceptor cannot be used after HiveMind LoggingInterceptor. The Registry successfully applies my HibernateInterceptor to service but fail to apply the Logging Interceptor. org.apache.hivemind.ApplicationRuntimeException: Unable to construct service doconline.Adder: Unable to lookup $Proxy0: $Proxy0 at org.apache.hivemind.impl.servicemodel.AbstractServiceModelImpl.constructNewServiceImplementation(AbstractServiceModelImpl.java:156) ......

Caused by: javassist.NotFoundException: $Proxy0 at javassist.ClassPoolTail.openClassfile(ClassPoolTail.java:300) at javassist.ClassPoolTail.checkClassName(ClassPoolTail.java:177) at javassist.ClassPool.checkClassName(ClassPool.java:709) at javassist.ClassPool.get0(ClassPool.java:572) at javassist.ClassPool.get(ClassPool.java:561) at org.apache.hivemind.service.impl.CtClassSource.getCtClass(CtClassSource.java:56) ... 48 more The problem seems occurs when javassist want to find the class file in classpath but cannot find it( Of course it cannot ). If I put Transaction Interceptor before the Logging Interceptor, all works well. --------------------------------------------------------------------- JIRA INFORMATION: This message is automatically generated by JIRA.
