I have vb6 activex dll that gets called by tomcat/apache through
another application. Can someone tell me how to debug this dll at run
time? Right now I am just printing messages to file which is not a the
right way

Several ways.

The simplest is to open up your DLL project. Go to Project Properties ->
Debugging Tab and enter which program to 'start' your application. Leave the
project open and start the 'user'.

You may run into trouble with a web application because of the isolation and
permissions your DLL and the IDE must run under. You may have to copy
VB6DEBUG.DLL into your web space.

I don't know enough about tomcat/apache concerning permissions.

Press F5 in your DLL project and choose "Wait for component to be created",
you could also set this in the project's properties. The other application
that uses your DLL must use late binding, as in:

Set o = CreateObject("Project1.Class1")

CreateObject has a second optional parameter which lets you specify a
different computer if VB6 is installed on a different computer, for example:

Set o = CreateObject("Project1.Class1", "192.168.0.100")

Or:

Set o = CreateObject("Project1.Class1", "VB6PC")

It's best to test on the same computer, as the second form might require you
to adjust your security settings. Search MS KB for "dcomcnfg".

As Ralph suggested, VB6 uses VB6DEBUG.DLL not your DLL. So you may have to
unregister your DLL first, but that maybe unnecessary especially if you are
using binary compatibility. If you have problems, just unregister your DLL.

The applicaiton that calls my dll requires the actual dlls to be copied
in a specific directory outside my project directory and registered with
regsvr32 command. The application runs with Tomcat/Apache and at some
point in the UI calls the DLL. I have no control on the application that
calls my dll neither can I do a CreateProject or unregister the dll.
However, I am running both on the same pc.

I am little confused. Can you shed some more light on this?
