原来项目在自己电脑上是能跑的，然后用SVN版本控制了。项目在运行过程中报错了。页面显示不出来报的错如下，哪位高手能帮忙看下是什么问题？Caused by: java.lang.ClassNotFoundException: purchaseAction from BaseClassLoader@17d565c{VFSClassLoaderPolicy@1b0c124{name=vfsfile:/D:/Alpha_lib/jbpm-4.3/jbpm-4.3/jboss-5.0.0.GA/server/default/conf/jboss-service.xml domain=ClassLoaderDomain@e62f6{name=DefaultDomain parentPolicy=BEFORE parent=org.jboss.system.NoAnnotationURLClassLoader@861f24} roots=[MemoryContextHandler@22555272[path= context=vfsmemory://a12i1s-wlvsp9-gdbdb7ix-1-gdbdbekc-6 real=vfsmemory://a12i1s-wlvsp9-gdbdb7ix-1-gdbdbekc-6], DelegatingHandler@22042053[path=adsjdbc.jar context=file:/D:/Alpha_lib/jbpm-4.3/jbpm-4.3/jboss-5.0.0.GA/server/default/lib/ real=file:/D:/Alpha_lib/jbpm-4.3/jbpm-4.3/jboss-5.0.0.GA/server/default/lib/adsjdbc.jar], DelegatingHandler@19856451[path=annotations-api.jar context=file:/D:/Alpha_lib/jbpm-4.3/jbpm-4.3/jboss-5.0.0.GA/server/default/lib/ real=file:/D:/Alpha_lib/jbpm-4.3/jbpm-4.3/jboss-5.0.0.GA/server/default/lib/annotations-api.jar], DelegatingHandler@28551387[path=antlr-runtime.jar context=file:/D:/Alpha_lib/jbpm-4.3/jbpm-4.3/jboss-5.0.0.GA/server/default/lib/ real=file:/D:/Alpha_lib/jbpm-4.3/jbpm-4.3/jboss-5.0.0.GA/server/default/lib/antlr-runtime.jar], oracle.i18n.text.converter] <IMPORT-ALL>NON_EMPTY}}
