#19355 — can't find in classpath, but only when running from the jar file

I'm trying to run a Java class in a jar file.  The jar file contains this class:

    com/exacttarget/wsdl/partnerapi/PartnerAPIStub.class

The manifest looks like this (not indented).

    Manifest-Version: 1.0
    Ant-Version: Apache Ant 1.8.4
    Created-By: 1.7.0_03-b04 (Oracle Corporation)
    Main-Class: com.exacttarget.wsdl.partnerapi.PartnerAPIStub

All the main class does is print "hello world".  It works (prints "Hello World") if I do this in the classes directory...

   java com.exacttarget.wsdl.partnerapi.PartnerAPIStub

This same class is definitely in the jar file as demonstrated by this command...

    bash-4.1$ jar tf PartnerAPI-test-client.jar |grep Stub.class
    com/exacttarget/wsdl/partnerapi/PartnerAPIStub.class
    bash-4.1$ 

but when I try to run the jar, with the environment exactly as it was when I ran the class separately, using this command...

   java -jar PartnerAPI-test-client.jar

I get this error output...

    Exception in thread "main" java.lang.NoClassDefFoundError: 
    org/apache/axis2/client/Stub

Obviously I'm missing something.  Any help would very much be appreciated.

I think you're missing a Class-Path attribute.
Class-Path: The value of this attribute specifies the relative URLs of 
the extensions or libraries that this application or extension needs. 
URLs are separated by one or more spaces. The application or extension 
class loader uses the value of this attribute to construct its internal 
search path.

or a classpath option
java -jar -cp pathtomyaxis2clientjar PartnerAPI-test-client.jar

That won't work. The -cp option is ignored with -jar.

If you use -jar you can only specify a classpath in the Class-Path: 
directive in the manifest, as explained in your previous posts.

Java will ignore the classpath option in this command.

I've supplied misinformation here.

Quoting from the java - The Java Application Launcher manual
<http://docs.oracle.com/javase/7/docs/technotes/tools/solaris/java.html#options>

-jar
[snip]
"When you use this option, the JAR file is the source of all user 
classes, and other user class path settings are ignored. "
[snip]

Thanks to Nigel and Lew for catching this.:)

see http://mindprod.com/jgloss/jar.html

Jars ignore the SET=classpath.  You need to put a classpath inside the
jar with a Class-Path attribute in the manifest.

Other have already told you about the classpath.

But try look at the message:

   java.lang.NoClassDefFoundError org/apache/axis2/client/Stub

It actually clearly states that it can not find a class that is
part of Axis2.

The solution follow easily from that analysis.

If you plan on programming in Java for the next 20 years, then you will
see hundreds or thousands of error messages - you need to learn to use
the information provided to resolve problems.
