[tushar panda]

 SEVERE: Error filterStart

SEVERE: Context [] startup failed due to previous errors  

i checked the log files and got this :

as the error says i do not have "LogFilter" class in "net.tushar" directory , but i have it.


my "web.xml" code is:

   <?xml version="1.0" encoding="ISO-8859-1"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

   version="2.5">

"LogFilter" code

   package net.tushar;
import javax.servlet.*;
import javax.servlet.http.*;
import javax.servlet.Filter;
import javax.servlet.FilterConfig;
import javax.servlet.FilterChain;
import java.io.*;
import java.util.*;



public class LogFilter implements Filter {
	public void doFilter(ServletRequest req,ServletResponse res,FilterChain chain)throws ServletException,IOException{
try{
		HttpServletRequest request = (HttpServletRequest) req;
		String ip = request.getRemoteAddr();
		System.out.println("remote addr:"+ip+"date is :"+new Date().toString());
                System.out.println("within request");
                System.out.println("filtering request");
  		chain.doFilter(req,res);
                System.out.println("remote addr:"+ip+"date is :"+new Date().toString());
                System.out.println("within response");
                System.out.println("filtering response");
}
catch(IOException ioe){
System.out.println("IOException raised :");
}
catch(ServletException se){
System.out.println("ServletException raised");
}
	}
	
	public void init(FilterConfig config)throws ServletException{
		String testParam = config.getInitParameter("test-param");
		System.out.println("Test Param: " + testParam);
	}
	public void destroy(){
		
	}

}
 

i am not sure but i think the culprit is "filter-class" declaration.

waiting for an answer

You folder location screen shot is showing path as \Root\WEB-INF\classes\net.tushar

Here net.tushar is wrong. It should be \net\tushar\LogFilter.class And why you are providing this class in Root. Provide this class in your application WEB-INF classes directory.

May it will resolve your issue.

i am testing so i have put it there.


in logfiles @line 14 ,it says "exception starting filter logfilter". i think something is here..(not sure)

[xsunil kumar]

I have copied your web.xml and filter class in My local tomcat server and i am not getting any exception in server log file. When i am using wrong folder name like net.tushar then i am getting same issue but using It should be \net\tushar\LogFilter.class its running without any exception. Check last line of your log file becauser server log will be appended in same log file. Verify with the time stamp given in your log file and your system time when you have started your tomcat server.

Is your filter class in the correct directory? Please list the directory structure of your package starting at webapps. Please read this Deploying web applications...
