Re: [Wrapper-user] java.lang.NoClassDefFoundError

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

Lindsay,
    Looking at your original classpath, it looks like your dcm.DipperDCM 
is a raw class file
that is not included in a JAR.   It is being  found because you have the 
"." directory included
on your classpath.

    Try adding that to the classpath in your wrapper.conf file:
wrapper.java.classpath.1=lib/wrapper.jar
wrapper.java.classpath.2=lib/comm.jar
wrapper.java.classpath.3=lib/log4j-1.2.8.jar
wrapper.java.classpath.4=lib/mysql-connector-java-3.0.14-production-bin.jar
wrapper.java.classpath.5=.

    As an aside, you can also do this:
wrapper.java.classpath.1=.
wrapper.java.classpath.2=lib/*.jar

Cheers,
Leif
