Getting java.lang.NoClassDefFoundError in JDO

[Former Member]

Hi all,

I am getting the above error when I was trying the Getting started with JDO example in NDS help. I am getting this error after the run Ant on biuld.xml i.e. while enhancing the class files. I have added the logging.jar in Build path.

The complete stack trace is as below:

enhance.Employee:

Any help will be appreciated.

Hi Jaydeep,

you have to add the "$"-entry in the classpath-property too. it is only added in the classpath.check-property in JDO-examle.

hi

the class LogController is not found at run time. If you are using a webdynpro project add the jar in the lib folder using the navigator. this would ship your files needed at runtime.

Hi Lakshminarayanan,

I am doing a web module project and the

logging.jar

is in the build path. Any thing else I need to do?
