导致以上原因的是因为javax.servlet.jsp.tagext.TagAttributeInfo有冲突
当前classpath中有两个version的javax.servlet.jsp.tagext.TagAttributeInfo class，一个在servlet.jar另一个在jsp-api.jar中。 jsp-api.jar的那个是好用的，它只包含javax\servlet\jsp这个包，而servlet.jar中也包含它，同时包含servlet需要的关键包。所以在classpath中jsp-api.jar要比servlet.jar先被reference。
另外在jboss3.2.*之后的自己带的lib中已经将javax\servlet\jsp从servlet.jar中分开了，分别是javax.servlet.jar（jsp-api.jar）和javax.servlet.jsp.jar（serlvet-api.jar）.
