Using Axis2/Java to generate code from WSDL

Question

I'm trying to use Axis2/Java to consume web services. In particular, I'm trying to generate Java skeleton code from a WSDL file.

I installed the libaxis-java package, but the package doesn't contain the WSDL2Java.sh script I was expecting. I tried to generate the Java code by doing:

java -cp /usr/share/java/axis.jar org.apache.axis.wsdl.WSDL2Java foo.wsdl

But I get the following error:

Exception in thread "main" java.lang.NoClassDefFoundError: org.apache.commons.logging.LogFactory
        at org.apache.axis.components.logger.LogFactory.class$(LogFactory.java:45)
        at org.apache.axis.components.logger.LogFactory$1.run(LogFactory.java:45)

Could not find the main class: org.apache.axis.wsdl.WSDL2Java. Program will exit.

Solution 1

Based on Riccardo Murri's answer, I was able to determine all the jar files required for the classpath:

java -cp /usr/share/java/axis.jar:/usr/share/java/commons-logging.jar:/usr/share/java/commons-logging-api.jar:/usr/share/java/commons-logging-adapters.jar:/usr/share/java/commons-discovery.jar:/usr/share/java/jaxrpc.jar:/usr/share/java/wsdl4j.jar org.apache.axis.wsdl.WSDL2Java foo.wsdl

Solution 2

You seem to be lacking the commons-logging jar in your classpath:

1. Install Ubuntu package libcommons-logging-java:

   sudo apt-get install libcommons-logging-java

2. Append /usr/share/java/commons-logging.jar and its relatives to your classpath:

   java -cp /usr/share/java/axis.jar:/usr/share/java/commons-logging.jar:/usr/share/java/commons-logging-api.jar:/usr/share/java/commons-logging-adapters.jar org.apache.axis.wsdl.WSDL2Java foo.wsdl

It's quite likely that there will be other dependencies missing; you might want to use the JarAnalyizer tool to find them and add to the classpath.

Looks like you're missing a jar on the classpath.
