Re: Axis integrated into existing web application?

Brian Ewins Thu, 06 Feb 2003 02:11:06 -0800

This isn't such a good idea. A webapp acts as the scope for <error-page> entries in its web.xml. This means that if you have an html webapp, you inevitably end up returning html errors to an xml client.

This is then complicated by the fact that some servlet engines change status codes on errors when returning custom error pages:
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=10373

This means that you end up sending an html 200 response instead of an soap fault with a 500 error!

Both the html response and the 200 status code are explicitly forbidden in sec 6.2 of the SOAP 1.1 spec, so you've lost interoperability right there.

Cheers,
Baz

Hello,

Anybody here successfully integrated Axis to existing web application instead of as a separate one? I cannot deploy services. Following is the command line and the exception. Any idea?
