how to pass xml instances from servlet to xform jsp

Hi,

i am integrating struts with xform. i made a demo application which runs on jetty.

problem: Not able to pass xml instances from servlet to jsp (xform).Hence, not able to display. getting " null" in getAttribute("XML") in jsp.

i am having a save action class.

===================================
SaveAction.java
=================================
package action;

import java.io.IOException;
import java.util.Map;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts2.interceptor.RequestAware;
import org.apache.struts2.interceptor.ServletRequestAware;
import org.apache.struts2.interceptor.ServletResponseAware;

import com.opensymphony.xwork2.ActionSupport;

import pojo.Student;

public class SaveAction extends ActionSupport implements ServletRequestAware ,ServletResponseAware{
Student student;
HttpServletRequest request;
HttpServletResponse response;

public String execute() throws IOException {
String str= new String("<book>"+
"<title >JAVA</title>" +
"<author>Manish</author >" +
" <language>English</language> " +
"<link>s</link >" +
"<rating>4</rating> " +
"<notes>sddsa</notes> " +
"</book>");
request.setAttribute("XML",str);

System.out.println("Save Action");
response.sendRedirect("/pages/aaa.jsp");
return "success";
}
public Student getStudent() {
return student;
}
public void setStudent(Student student) {
this.student = student;
}
public void setServletRequest(HttpServletRequest arg0) {
request=arg0;

}
public void setServletResponse(HttpServletResponse arg0) {
// TODO Auto-generated method stub
response=arg0;
}
}
==================================================================================

Does your application work on Tomcat? Are you saying that this is a
Jetty-specific issue?

So you are setting a request attribute in a Struts action, and then
reading it in a JSP. This doesn't seem to have something to do with
Orbeon Forms, does it? Or am I miss-reading your code?

Re: how to pass xml instances from servlet to xform jsp

Hi Manish,

Looks like it is not a problem with the servers.

You may not want to do a response.redirect() to your jsp to pass your attribute, but you should use request.forward() instead.

But the best way is just to let your struts flow complete it course, and bind your jsp url to the "success" forward config in your struts-config.xml

Marwoto.

In reply to this post by manish_suriya

not orbeon related :

example,

RequestDispatcher rd = request.getRequestDispatcher("/pages/aaa.jsp");
rd.forward(request, response);
