Error while deploying java webservice

Could someone help开发者_如何学JAVA me on this.

I have created simple java web service using Java 1.6, tomcat-6.0.20 and axis2-1.4.1.

While deploying the application, it returns following error message:

SEVERE: Servlet.service() for servlet jsp threw exception
org.apache.jasper.JasperException: Unable to compile class for JSP: 

An error occurred at line: 22 in the generated java file
The method getJspApplicationContext(ServletContext) is undefined for the type JspFactory

Seems that there is an incompatibility of libraries loaded.

See this post and this

The first post explain the error:

In Tomcat 6, the JSP API classes are found in jsp-api.jar and servlet API classes are found in servlet-api.jar, with both located in the lib directory of the Tomcat 6 installation. Any servlet.jar you find involved with this server would contain out of date classes for this server.

So... check if you don't have an extra servlet.jar:

Make sure you don't have a copy of servlet.jar in the WEB-INF/lib of your webapp or somewhere else involved with the running server, such as in the lib/ext directory of your JDK or JRE.

I hope it helps you.
