Facing problem while compiling Action Class

Hi All,

I am new to Struts 2 application.
I am facing problem in compiling an below Action Class.

package com.kogent.action;

import com.kogent.User;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import org.opensymphony.xwork2.Action;

import org.apache.struts2.interceptors.ApplicationAware;
import org.apache.struts2.interceptors.ServletRequestAware;

public class GetUserAction implements Action, ServletRequestAware, ApplicationAware{
	HttpServletRequest request;
	Map application;
	
	public void setServletRequest(HttpServletRequest request){
		this.request = request;
	}
	
	public void setApplication(Map application){
		this.application = application;
	}
	
	public String execute() throws Exception{
		String username = request.getParameter("username");
		ArrayList users = (ArrayList)application.get("users");
		
		User user;
		if(users != null){
			Iterator it = users.iterator();
			while(it.hasNext()){
				user = (User)it.next();
				if(username.equals(user.getUsername())){
					request.setAttribute("user", user);
					break;
				}
			}
		}
		return SUCCESS;
	}

}

errors am getting is:

package org.opensymphony.xwork2 does not exists.

But i have this all kinds of package in ..

Struts2Application/WebContent/WEB-INF/lib folder.

Above folder contains below jar files.

struts2-core-2.0.11.jar
xwork2-2.0.1.jar

Moreover below is the Class path:

%CLASSPATH%;D:\Eclipse_wrksp\Struts2Application\WebContent\WEB-INF\lib\xwork2-2.0.1.jar;D:\Eclipse_wrksp\Struts2Application\WebContent\WEB-INF\lib\struts2-core-2.0.11.jar

What could be wrong in above? Is there anything getting wrong while compiling GetUserAction.

Please Help.

Thanks in Advance.
Jay Shukla

Can you check if there are more than one xwork.jar in the same path ? or, more than one org.opensymphony.xpath.* entries available in the same classpath ???

Hi dawn,

Thanks for Reply.

I have manually set the classpath and moreover i have attached exact screen shot of output of echo %CLASSPATH% commnad.

Hope this may help you.

Hi Jay,

It's a compilation problem, so the jars should be added to your Eclipse project. Adding jars to CLASSPATH will not help in compilation, because while compiling, Eclipse overrides the classpath with only jars that have been added to the project.

Hi Karthik,

Jars are already present in the my eclipse folder in lib folder (D:\Eclipse_wrksp\Struts2Application\WebContent\WEB-INF\lib).

Do you want to me to add 'Add As External Jars' in the Eclipse porject build path??

Thanks.

Hi Karthik,

I tried by adding jars in 'Add External Jars..'

But in vain.

What other option could be tried?

Thanks.
Jay.

They need to be added to the build path in the project properties.

Please, please don't attach screenshots for textual information: cut and paste exists for a reason.

Hi Jay,

Ok I got the problem now after looking into xwork. The correct package name is com.opensymphony.xwork2.Action, not org.opensymphony.xwork2.Action.

In fact, Eclipse IDE itself would have flagged this problem by highlighting the line in red.

And yes, you also have add both jars to the build path. Since it's already available in one of your project folders (./lib), you can use the "Add jars" button instead of "Add external jars".

Cheers
Karthik

Ah, good catch; missed the "org".

Hi David,

I added those Jars in Build Path as well but in vain.

I compiled same kind of java file earlier same way but i don't know why such error is coming this time.

Thanks.

oh my Bad.

Thanks Karthik for pointing this problem.
But surprisingly it didn't highlighted this problem.

Thanks.

Sure it did: "package org.opensymphony.xwork2 does not exist."

Are you talking about your IDE not indicating it was an error? If so, your IDE is not configured correctly.
