This is similar to 2nd link which I had posted above. I tried dumping thing, but some error was given by oracle. Also I couldn't figure out why exp command was not being recognised.
But a new problem has occured. I'll explain the original scenario first. One mate was working on is major project which required oracle, netbeans and tomcat. The issue was transfer the whole thing to another laptop to make it run. I did it all, everything went smoothly, from all the tables to tomcat settings to everything. But when I'm running any project file from netbeans, its asking for tomcat pass. The original user (who made the project), hadn't installed tomcat on his system, so he has no idea about it. Default pass is not working. What to do now?
