java - Eclipse Server Services encounters an error

Question

Note: Yes I have followed all of the other similar issues, I've downloaded 10+ .jars and tossed them into the lib file. nothing worked.

Note2: I am using eclipse 2020, jdk1.8, tomcat7.0.107, axis2-1.7.9

I have no idea what I'm doing but my university teacher says I need to follow this YouTube guide from 2014 for my 2021 IWS class. https://www.youtube.com/watch?v=lgY0pLadraE Unfortunately, everytime when I get to the 1:20 mark where I run my method on the server I get this ridiculous error.

Answer 1

ClassNotFoundException and NoClassDefFoundException usually mean that your are missing a library. In your case the classes in the org.apache.ws.commons.schema are part of XmlSchema.jar.

Check out the dependencies of your version of Axis2, e.g. on Maven Repository and add the appropriate version of XmlSchema.jar to your project.

Edit: you can also download the entire Axis2 binary distribution and add all jars to your WEB-INF/lib folder.

A better alternative would be to use Maven or gradle as your build tool. This way you'll never miss a dependency.
