I am attempting to do some database pooling.  I have a .class file to use in my source code but how do I compile my code since I don't have the .java source.  When I attempt to use the classes in that file, it says I can't.  I attempted to change my classpath, and also put the .class file in the same directory as my source code, but I still get errors.  Any ideas?

Which errors do you get? Did you put class file according to package inside?

Sounds like the classes may be in a package, in which case they'll need to be in directory that corresponds to their package name.

eg. If you classpath includes the directory /classes and a class is in the package a.b then class file will need to be put in /classes/a/b.
And you'll need to import a.b.*; to use it in your code.

Then the class is not accessible from your classpath:
- is the class in a package?
- what is your classpath ?
- where is the class located ?

Put the DbConnectionBroker.class in the same directory where  your java program is and add the complete path of DbConnectionBroker.class into  your classpath including filename.And before compile in DOS say:
classpath=%classpath%;.
Hope this works.
good luck.
