Please Help, m trying since 2 days to resolve it..... :confused::confused:

[r035198x]

One of the steps in your tutorial says you should

"copy lib/core/*.jar to [webapp]/WEB-INF/lib". Did you do that?

[mburnwal]

i copied all jars files from it... but still same error.... :(

plz help

[r035198x]

The error message you are getting means that you are missing a jar file (one that has something to do with xwork) from your classpath which in this case is your [webapp]/WEB-INF/lib. Are you sure you have a jar file that has something to do with xwork in your [webapp]/WEB-INF/lib?

[mburnwal]

My environment variables are set as:::

User variable

name: JAVA_HOME
value:C:\Program Files\Java\jdk1.6.0_20

name:path
value:C:\Program Files\Apache Software Foundation\Tomcat 6.0\bin;.;C:\Program Files\Java\jdk1.6.0_20\bin;.;

System variables:

plz help

[r035198x]

No, this has nothing to do with your environment variables.
Read my reply above again.

[mburnwal]

I read your reply.. but can you please mention which jar files... its small application.. plz help me in it.

[r035198x]

Do you have a jar file called xwork.jar (or similar) in your application's WEB-INF/lib?

[mburnwal]

i have

xwork-1.0.5.jar
xwork-2.0.4-sources.jar
inside WEB-INF/lib

[r035198x]

now m getting this error::

HTTP Status 500 -

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

org.apache.jasper.JasperException: java.lang.NullPointerException
org.apache.jasper.servlet.JspServletWrapper.handle JspException(JspServletWrapper.java:536)
org.apache.jasper.servlet.JspServletWrapper.servic e(JspServletWrapper.java:368)
....

When does this happen? Do you have a JSP that you are trying to access? What is the code for the JSP.

Also make sure that you don't have different versions of the same jar file in your WEB-Inf/lib

[mburnwal]

i have 2 xwork jar files


xwork-2.0.4-sources
xwork-1.0.1

webwork-config-browser
webwork-2.2.7
webwork-src-2.2.7

xwork-2.0.4-sources
xwork-2.0.4-sources
xwork-1.0.1

[mburnwal]

Hello html world
<hr/>
<%
out.println("Hello jsp world.");
%>
</body>
</html>

[r035198x]

Go through the steps mentioned in your lesson again. Most likely you missed a step (the same way you initially missed the step about copying jar files)

[mburnwal]

actually i m thinking to rebuilt the whole application again... may starting wid installaton parts.. ;-)

I will surely put the success of it soon. thnxx a lot :)

[mburnwal]

i am using this IDE for the first time... so stuck....
