In order to debug your component with Visual J++ 6.0 you can attach your java class file to the Inetinfo process. You can attach to the Inetinfo process by selecting Processes from the Debug menu. This will present you with a list of available processes that are currently running on your computer. If you have previously called an .asp file that creates an instance of your component, you will see the Inetinfo process in the list of processes available for attaching. Select Inetinfo, and you will be able to use the debugger functionality within the component.
Note If the application that you are using for debugging is isolated, the appropriate process to attach to will be an instance of mtx.exe. The process will not appear by default in the list of available processes. In order for it to appear, you must change the identity for the COM+ application that corresponds to the isolated application to either "interactive user" or a user account with rights to access the server interactively.
