Problem using JDBC connection in NetBeans IDE

[Nikhil Reddy Lingala]

Hi all..
I have gone through FAQ's section. But I have not found any answer for my problem, so I am posting it here.
I am able to connect to the Oracle database using a "hello world" kind of program(like able to retrieve the data from a table in the database). But the problem is when I am trying to develop a small login application using JSP and Servlets, I am unable to connect. I am doing this application through Sun NetBeans 5.5 IDE. I have included the .jar(ojdbc14.jar) file in the libraries of my project. But still I am unable to connect to the database.
I have put that "connection" code in a try-catch block and the code I have written in catch block is getting executed.
How do I resolve my problem?

Is there a stacktrace or other information you have on the exception which is being thrown?

[Nikhil Reddy Lingala]

No, I didn't include any code to print the stack trace..
I have just written a println statement that prints "error in this connection.java"

try{
//code for connecting database, which worked when tried with a simple
//program without using IDE
}catch(Exception e){
System.out.prinln("excetion in connection.java");
}

hi,

then MAKE it print the stacktrace.

If you print the same message for all exceptions, it won't give you any usefull information.

Yes... I have given

e.printStackTrace();

to provide me the info wanted.. I was able to debug....
the problem was with the URL in the getConnection() method...!!!
