Exception occurred during code generation for the WSDL : java.lang.NoClassDefFoundError: org/apache/ws/commons/schema/utils/NamespacePrefixList

Question

I am using Tomcat 7 server and Axis 2 1.7 runtime in eclipse.

I have a WSDL file which is generated in Axis 2.

so go for Topdown approach to generate a webservice class (skeleton). I selected my configuration as Axis in server run time. when tried to click finish it is showing following error: "Exception occurred during code generation for the WSDL : java.lang.NoClassDefFoundError: org/apache/ws/commons/schema/utils/NamespacePrefixList"

I thought it is a jar miss so i first included XmlSchema-1.4.2.jar the error hasn't resolved. so i deleted that jar and tried with latest jar downloaded from java2s (xmlschema-core-2.0.1.jar). Still i have the same problem.

Please help me to solve this issue.

This same issue also persist when trying to create a client from WSDl in eclipse.

Kindly help me to solve this with steps. Thanks

I have the same issue: I also added xmlschema-core-2.2.1.jar in Web App Libraries but it doesn't work. Hope that someone will help us. – Ethnocentrism

Try Axis2 1.6.X instead of Axis2 1.7.X. – Irresolution

Answer 1

Solved this issue: in webContent/WEB-INF/lib add xmlschema-core-2.2.1.jar; then, ensure it is added in Web App Libraries on your build path; finally close and reopen eclipse before generating web service client. This worked for me.

Make sure you restart the eclipse - it didn't work for me until I did. – Smutch

This solved my issue on Eclipse Neon. Should eclipse be notified so they fix this bug in the WTP project? – Bithynia

This also worked for me. The only clarification would be that I had to drag and drop the xmlschema-core-2.2.1.jar into the webContent/WEB-INF/lib folder in Eclipse's project explorer. Just adding the xmlschema-core-2.2.1.jar as external library in the project's build path didn't work. Also, it's fundamental to restart Eclipse for the changes to take effect. – Jaclynjaco

Answer 2

In my case this error is occasioned for using axis2-1.7.3, my solution was change and use axis2-1.6.4
