The javax.wsdl.extensions.ExtensibilityElement class resides in the wsdl4j.jar in the axis/lib directory - so that JAR has to be in your classpath. So I guess it isn't in your class path variables of your project's Java Build Path. To ensure that your installation is in order, it might be an idea to verify from the command-line that its works.
well I have it in my class path. These are my .classpath file entries:
<classpathentry kind="lib" path="C:/Documents and Settings/himanshub/workspace/Converter/WebContent/WEB-INF/lib/commons-discovery.jar"/> <classpathentry kind="lib" path="C:/Documents and Settings/himanshub/workspace/Converter/WebContent/WEB-INF/lib/commons-logging.jar"/> <classpathentry kind="lib" path="C:/Documents and Settings/himanshub/workspace/Converter/WebContent/WEB-INF/lib/wsdl4j.jar"/> <classpathentry kind="lib" path="C:/Documents and Settings/himanshub/workspace/Converter/WebContent/WEB-INF/lib/log4j-1.2.8.jar"/> <classpathentry kind="lib" path="C:/Documents and Settings/himanshub/workspace/Converter/WebContent/WEB-INF/lib/axis.jar"/> <classpathentry kind="lib" path="C:/Documents and Settings/himanshub/workspace/Converter/WebContent/WEB-INF/lib/jaxrpc.jar"/> <classpathentry kind="lib" path="C:/Documents and Settings/himanshub/workspace/Converter/WebContent/WEB-INF/lib/saaj.jar"/> <classpathentry kind="lib" path="C:/Documents and Settings/himanshub/workspace/Converter/WebContent/WEB-INF/lib/axis-ant.jar"/>
moreover I manually copied these files to my project's lib folder but still it results to the same error.
Axis 1.2 and 1.3 are distributed with wsdl4j-1.5.1.jar, commons-discovery-0.2.jar, commons-logging-1.0.4.jar
You can always check to see if that JAR actually contains javax.wsdl.extensions.ExtensibilityElement (as javax/wsdl/extensions/ExtensibilityElement.class). Copy the JAR to a different location and the change the copy's extension from .jar to .zip and then simply look into it.
Sometimes it's just easier to get things working (and figure out what you need in your classpath) from the command-line. Work in a console window. Simply create a .bat that contains something like
Keep adding to the %AXISCLASSPATH% until Java2WSDL is finally happy. Above you can see the path that I had to create to make WSDL2Java happy.
However when working with the command-line keep in mind:
IIRC maximum length for both the entire command-line and a single environment variable is 2048 bytes for Windows NT, 2000 and 8192 bytes for Windows XP and above (could have been worse).
When there are spaces in the path, you have to enclose the file pathname in quotes to stop option parsing from breaking.
I'm still paranoid from the olden days where everthing was limited to 256, so your base library path of "C:/Documents and Settings/himanshub/workspace/Converter/WebContent/WEB-INF/lib/" 79 + 2 quotes = 81 characters would make me sweat - my base library path (D:\etc\axis\lib) has only 15 characters and no spaces.
