Hi All,

I have installed Weblogic SP3. I am trying to make a Web Service which uses JAXB to convert xml into Java Objects. My Web Service is a simple Java class which I compile in Eclipse 3.1. Because I am using JAXB so I created my Project in Eclipse and I set the 'project specific complaince' to 5.0 as it is required for working with JAXB classes.

Problem:
Once I have compiled my project successfully, I copy my classes to a folder from where I am running my Ant build script to generate the web-services.xml. The script is as follows:

<project name="buildWebservice" default="generate-typeinfo">
<target name="generate-typeinfo">
<source2wsdd
javaSource="com/services/BaseWebServiceSimulator.java"
ddFile="ddfiles/web-services.xml"
serviceURI="/MyService" />
</target>
</project>

The classes generated from the xsd by using JAXB are also in the same folder under the directories com/vipul/jaxb/appdefaults.

But when I run this script it gives me the following error:

C:\>cd webservice

C:\webservice>ant
Buildfile: build.xml

generate-typeinfo:

BUILD FAILED
file:C:/webservice/build.xml:6: javadoc execution failed

Total time: 1 second
C:\webservice>


It gives me an error "package javax.xml.bind does not exist". I don't know why. I even copied the jar file "jaxb-api.jar" that is installed when we install Java Web Service Pack 2.0 in the same directory where I am running my build script, but it still gives me the same error. I also tried exploding the jar files into the same directory but still the error persists.

Can someone give me a clue as to what is happening?

Thanks in advance!

Hi,

The Java version your are using is older than the one used to build BaseWebServiceSimulator.
