You probably already went down the path of checking if the JVM classpath was somehow changed (WRKENVVAR *SYS is there a CLASSPATH entry?) . Normally you could change those values after starting the JVM and it wouldn't affect the currently running apps *unless* the app itself was doing some class re-loading at some point in the life cycle.

You might take a look at the running job with WRKJVMJOB and see what the classpath looks like and then work backward to the error and see if the object referred to is in the the classpath referenced by the job.

We are using the IBM Integrated Web Services Server and it's been working
great for us.

However, in just the last few days we noticed that several web services that
have been installed for several months and running fine, are now running
with a Yellow/Warning status when viewed through the HTTP Admin page. Note
that as early as the first part of last week all was running fine and there
have been no changes made to the iSeries in terms of software installed or
PTFs installed or anything similar. At least none that anyone will admit

Upon looking in the log files, we are seeing this error repeated over and

SEVERE Exception occured in
::thread=HttpServer : 197

javax.servlet.UnavailableException: CWPWC0029E: Servlet
_ibmjsp.axis2_2D_web.Error._error500 was not found, it maybe missing another
required class.

Check your classpath to ensure that all classes required by the servlet are

Which seems to indicate that an axis2 servlet or class has gone missing

That seems unlikely unless it was deliberately removed by someone as we have
not added any software to this iSeries for several months.

At this time we are focusing on figuring out just what exactly is missing
and where it is missing from and then replacing it.

With the Websphere Application Server Express at V6.1 and higher, I know
where to look for all the objects used by Websphere under
/QIBM/ProdData/Websphere/AppServer/V61/Express/ .

With the Integrated Web Services Server I am not sure where to start
looking. I have checked the actual /www/wasservername/ directory
structure where the services themselves run from but that does not help me
at this time (I don't think) in figuring out where the supporting
classes/servlets reside.

I'm currently at a loss as to where to look next to resolve this issue so
any suggestions at all would be welcome.
