Error logging in Java web service

[Mahita Ande]

Hi,
I have a java web service built on jax-ws. This web service is installed on a Unix server and runs as a background process. I start the process using the java command for the .jar file. However after running for sometime the service stops running automatically. It appears that either there is an error or some other process is l killing web service process. I do not have a way to say if the web service process stops because of an error. Could you please suggest how I can log errors that causes the service to stop in a java web service hosted on a Unix server.

Thank you,
Mahita

Pass this in as a -D parameter when starting your background process : com.sun.xml.internal.ws.transport.http.HttpAdapter.dump=true

Thank you.
Could you please let me know the location of the log files which contain these errors.

System.out stream which is stdout. Therefore if you put a '>' in your command line that invokes the background process , you can specify a file destination to capture the output.

I'm being intentionally ambiguous here because this is common system knowledge which you should already know. Use Google if you need help, or take a class in Java at your local community college for more information.

Is your web service made as web application? Shouldn't it be running on an app server like Tomcat?

How are you starting your service?
