My java webapp hosted within a tomcat 7.0.39 needs xvbf to write into images and output them to the client. When I open the servlet which handles the image writing I get the following error message:

The block of code where the error is thrown is the following:
public void init(ServletConfig servletConfig) throws ServletException {
super.init(servletConfig);
//
m_frame = new Frame(); // Line 46 in GroupOverview.java
m_frame.addNotify();
}
How do I solve this issue?
I fail to understand why you think you need xvfb to write to images in a headless environment.
You most certainly can do image (even Graphics2D) manipulation and ImageIO without xvfb. I do TIFF transformations, color model conversions, etc. in a headless environment without xvfb, and without needing to create Frame. You may want to dig a bit deeper.
But as a quick fix, try setting -Djava.awt.headless=true and see if that helps.

I am newbie to services. I am trying to make Service for login module by using axis2 framework. I made Web Dynamic Project in eclipse and generate java skeleton from wsdl. I made WAR file and deploy it on wso2 application server.After that i open the application server and perform the following steps.
open the Application list
click on "Go To URL" in Action
click on services
I got the following exception

Can anybody help me? Why is it giving exception.

It seems that the problem is with the wso2 not with your application. The addressing module is something internal. Review your wso2 configuration and installation or install a more recent version.
Following is the code which works fine when it is in main() method. Compiles and gives .jasper file as an output
package com;
import net.sf.jasperreports.engine.JRException;
import net.sf.jasperreports.engine.JasperCompileManager;
public class JasperCompile {
public static void main(String args[]) throws JRException {
JasperCompileManager.compileReportToFile("C:\\temp.jrxml", "C:\\temp.jasper");
}
}
But when I embed following line from main() method to servlet's doGet method then it doesn't work
JasperCompileManager.compileReportToFile("C:\\temp.jrxml", "C:\\temp.jasper");
Following is the stack trace.

what difference it makes when we write code in main() method and server side ?
Your version of Apache Commons Digester is incorrect. Review all dependencies of JasperReport.
This error seems quite mysterious for me that what the actual cause of this error might create on the web service using apache cxf as ref implementation.
Please any one can help for error. My error message is as follows:

How is cleared these error.please guide me.
The error message says it all:
org.apache.axis2.AxisFault: namespace mismatch require http://ws.retailer.com found http://ws.retailer.com/
One URL has a trailing backslash, the other doesn't.
You can configure your server. Here's the documentation for "Apache re-writes":
http://httpd.apache.org/docs/2.0/mod/mod_dir.html
Easier, just make sure your endpoint exactly matches the URL.
We have been searching a WYSIWYG editor for our Spring Project and we decided on CKEditor but we also needed an plugin for to insert iamge from localhost so I tried to implement CKFinder for Java. But I couldn't event make work CKFinder's example app work.
