[解决办法]
我遇到的问题和你一样，我整合jbpm4和sprring的时候遇到的，我觉得这是jar版本的问题，这个最麻烦。。。。。。。。
[解决办法]
原以为是jdk1.6的原因，降到1.5好像也不起效果，感觉是parse的时候出问题了，请大牛就我于水火？
protected void parse(StreamInput streamSource) {
isConfigured = true;
JbpmConfigurationParser.getInstance()
.createParse()
.pushObject(this)
.setStreamSource(streamSource)
.execute()
.checkErrors("jbpm configuration " + streamSource);
}
就是跟到这里出错了。
[解决办法]
找找看tomcat lib 文件夹下是否有 xercesImpl.jar
换成最新版本就OK
[解决办法]
jbpm4.0的问题，我换成jbpm4.2之后问题消失
