Brian,
Sorry I don't quite understand you. Do you suggest that use Axis as an independent web app? I removed the error page configuration from my web.xml. But the result is the same. My question is why I cannot even list the services published if I integrate it into my existing web app?
Thanks,
zhaohua

I know that was your question, I was just suggesting that integration is the wrong way to go in the first place.

Ok, trying to help with your current problem, it's this error:
java.lang.NoClassDefFoundError at org.apache.axis.configuration.FileProvider.configureEngine(FileProvider.java:210)

(it is a bit buried, but its in your message)

This just means some jar is missing, or in the wrong place in your classpath. If you run happyaxis.jsp - you should be able to just copy it into your integrated webapp from the axis webapp - it may help you to spot what exactly isn't there. If you run fingerprint.jsp as well, it provides some useful info about your setup that helps people on the list to diagnose setup problems. Neither of these depends on anything else in axis to run.

Cheers,
Baz

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.

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?
