Getting a NoClassDefFoundError on Class that is in Library List

[Steve Dyke]

I am getting this error even though there is a jar file in the app library with this class listed.

com.ibm.ws.webcontainer.servlet.ServletWrapper service Uncaught service() exception thrown by servlet DrawingNumberControllerServlet: java.lang.NoClassDefFoundError: com.itextpdf.io.font.FontProgramFactory (initialization failure)

This one cleared up after restarting the server however the following is appearing now.

com.ibm.ws.webcontainer.servlet.ServletWrapper service Uncaught service() exception thrown by servlet DrawingNumberControllerServlet: java.lang.NoClassDefFoundError: org.slf4j.impl.StaticLoggerBinder

And I have searched my web project and can find only find slf4j-api-2.0.99.jar

I did some digging and then added this jar:

slf4j-log4j12-1.7.30.jar

This stopped the java.lang.NoClassDefFoundError however, I get this in the console log:

I am not sure what jar I need to delete.
