Re: [Wrapper-user] ClassNotFoundException with WrapperSimpleApp

[Leif M. <lei...@ta...>]

Lin,
Could you please resend your wrapper.conf and wrapper.log files?  It looks
like there were some problems getting onto the list and the original mail
with the attachments didn't come through.
Also please make list posts to the wra...@li...
address.

The Wrapper reads the configuration file and uses that to build up the java
command line.  Once the JVM is launched however, it does its own
classloading.   The WrapperSimpleApp loads your main class within the JVM
but does not do anything special with classloaders or the class path.

I should be able to spot your problem with the wrapper.conf and wrapper.log
files.

I assume the path to the Martini-assembly-0.1-SNAPSHOT.jar file is
correct.  One problem I have seen in the past is with a corrupted jar
file.  Please make sure it has not been corrupted by an ASCII ftp transfer
or anything like that.

Cheers,
Leif
