Help!!! Connecting to a DB

[uni]

hi,

I am a beginner at Jbuilder and I am writing a test class which connects to a database. I have written the following code, but I get the error -

" java.lang.NoClassDefFoundError: junit/textui/TestRunner
Exception in thread "main" "

Does anyone know what I may be doing wrong, or what I have to do to get this to work?

Thanks heaps.

The error is nothing to do with your test class. The clue is in the error message. A NoClassDefFoundError means the compiler can't find a class file it needs, and is usually followed by the name of the class it is looking for, in this case junit/textui/TestRunner.

I guess this means you are using Junit to test your class, in which case you should have junit.jar on your classpath (e.g. something like set classpath=%classpath%;c:\junit3.7\junit.jar).

Incidentally, test classes for Junit usually extend junit.framework.TestCase, have methods called testXxxx(), and typically create a dummy database class rather than connect to a real database - see the Junit docs.

When setting the classpath, how do you cope with spaces?
For example, my install dir is "D:\Program Files\Eclipse\junit"
I have tried setting ";D:\Program Files\Eclipse\junit" and ";D:\Program%Files\Eclipse\junit" in the classpath (without the "" marks obviously), but nothing seems to work.

1. The shortcut to do the above is use the '.'

set classpath=%classpath%;.;c:\junit3.7\junit.jar;

where . represents the current working dir

which may avoid confusion when the folder name has spaces.
