Hi,
I had a Java application, Scarab, successfully deployed under JRun4.
Then we stopped using it for some time, and when I came back to it, it
no longer worked. We reinstalled JRun4 as part of a Cold Fusion upgrade,
but I'm unable to get Scarab to work again.
I've reinstalled following the procedure that worked last time, and I
get a 500 error when browsing to the servlet, the error log for the
server shows:
22/05 02:35:06 error Could not pre-load servlet: JSPServlet
[1]java.util.zip.ZipException: invalid entry size (expected 1939669000
but got 727 bytes)
Subsequent attempts to browse to the servlet result in a different error
in the log:
22/05 02:37:20 error
java.lang.NullPointerException
at org.apache.turbine.Turbine.doGet(Turbine.java:318)
Scarab also comes with a standalone Tomcat that it can run in, and I've
tried running it there and it works fine, but we'd rather deploy it on
JRun if possible.
I'm deploying Scarab as a WAR file which I'm dropping into the root of a
JRun server instance I created just for Scarab (C:\JRun4\servers\scarab)
Does anyone know what could be causing this?
Thanks in advance.
Full stack trace is below:
