org.apache.commons.lang.NotImplementedException in EntityManagerFactoryImpl.createEntityManager()

[Brian N]

Hi all,

I'm new to SimpleJPA, and have run Getting Started as best I can. But
I get the following error - does anyone have a clue on how to fix it?

Looks like you don't have Apache Commons Lang in your classpath…

I think so. commons-lang3-3.1.jar is in my classpath, but I get this
error anyway?

I just checked again, and commons-lang3-3.1.jar is in my classpath...

Yeah, looks like that is too new… try commons-lang-2.x
