Error upon runnnig JDeveloper 10.1.3.4: java.lang.NoClassDefFoundError

Question

We are migrating from JDeveloper version 10.1.3.1 to 10.1.3.4. We extracted the JDeveloper 10.1.3.4 to C:/jdeveloper. However, upon starting, we encountered the following error:

Anyone encountered the same error before?

Answer 1

I fixed the problem by adding a lib directory inside JDeveloper installation. For example: C:/JDeveloper10133/lib

Then I added the missing jar file (xmlparserv2.jar) inside the lib directory such as:

C:/JDeveloper101.3.3/lib/xmlparserv2.jar
