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.

The same code and deployment works without error on my local tomcat apache server, but not on that of my web host provider.
Thoughts?
Apparently the error logged is related to my Script object but is not the real problem. The issue was we neglected to update the database table schema at our web host provider site.
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 have this jsp page where it calls the servlet class.In this servlet class it calls another java class.This java class is then attempting to locate a folder named "profiles".However when I tried running the jsp page on a browser it keeps returning ClassNotFoundException(Is it caused by specifying the wrong directory or missing JAR files?).The question I am asking is:How do I get the correct pathing of that folder?
EDIT:
Here is the code:
In UserClientSearch.jsp:
<form id="form" method="post" action="UserClientServlet">
In UserClientServlet.java:
String value = request.getParameter("screenName");
request.setAttribute("screenName", value);
UserClientFilterSpam fs = new UserClientFilterSpam();
ArrayList<String> content= fs.filterSpam(value);
In UserClientFilterSpam.java:
try {
lds.init("profiles");
} catch (LangDetectException ex) {
System.out.println("Error encountered: "+ ex);
}
Here is the stacktrace:

You need to make sure that it is included in the deployed web application. If it is a 3rd party JAR file it can reside in the web app's WEB-INF/lib folder.
I have 2 eclipse projects A and B. A is a web project.I'm trying to call a class in project B from controller of project A.I have added jar of proj B in build path of project A.
Projects are compilation error free.But I'm getting runtime exception as below:

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.
