Starting JMeter

[James Farrier]

Hi all I am new to this list and have the following problem.

 

When I try to start JMeter I get the following error:

 

java.lang.reflect.InvocationTargetException:
java.lang.ExceptionInInitializerErr

or: java.lang.NullPointerException

        at org.apache.jmeter.gui.action.Help.<clinit>(Help.java:51)

Any help on this would be greatly appreciated

 

Thanks in advance
