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. |

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. |

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.

Any help would very much be appreciated. 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. Arne |
