Are there any issues with running batch files that call external programs when Tomcat is set up as an NT service. I have a problem that when using the startup.bat my COBOL routine gets kicked off fine, but when Tomcat is a service the COBOL returns an error code and never executes. I have a feeling its to do with environment variables and I am still investigating, but I thought I would just ask if there were any issues with doing this. Thanks. Dave [EMAIL PROTECTED]
