//After 4 months of workk
Here is what I did

The main things u have to consider while migrating from JRUN to TOMCAT are:

1)web.xml
Some patterns acceptable in jrun are not applicable here in tomcat
//individually check for each and every pattern by commenting ...
E,g
/*Controller [works in jrun]
/controller [change like this in tomcat]


2)necessary jar files:
place the necessary jar files for your application in your tomcat/shared/lib
It can be refernced in your previous jrun environment jrun/servers/lib

3)see files like .properties
here you can modify the information like path,database details ..etc

To add on:

Also When ur running tomcat ,,look for tomcat icon: 'll be there on the system tray

[B]Right Click-->Configure-->Java TAB-->java classpath-->
add neccesary jarfiles path
e,g:E:\Program Files\Apache Software Foundation\Tomcat 5.5.8\shared\lib\remobj.jar;;[/
B]

Hint: Look for log files to see what classes are needed
And that class file is in what jar file
