tomcat6整合JBPM4.4包问题

tomcat6跑jbpm4.4应用中,启动访问时正常成功,但是任何一个jsp页面时报一下错误:

 

Caused by: java.lang.ClassNotFoundException: de.odysseus.el.util.SimpleResolver

 

或者如下错误:

 

javax.servlet.ServletException: java.lang.LinkageError: loader constraint violation: loader (instance of org/apache/catalina/loader/WebappClassLoader) previously initiated loading for a different type with name "javax/el/ExpressionFactory" org.apache.jasper.servlet.JspServlet.service(JspServlet.java:275) javax.servlet.http.HttpServlet.service(HttpServlet.java:717)


在网上搜了下解决方案,总结如下:

        1.删掉tomcat6的el.jar,加入juel-api.jar到tomcat6/lib下,  注意应用下面不要留juel-api.jar了,        

        2.再将加入juel-impl.jar,juel-engine.jar 应用项目下。

经验证过的,希望对同胞们有帮助
