Java.lang.Null Pointer Exception

Hi,

A couple of days ago I configuered and launched successfully a SAS Enterprise Miner on my SAS OnDemand for Academic account. 

This evening I tried to opena new session again and I have the following mesage: "The application can not load the defintions of the SAS enviroment. Perhaps the place of the files or their content is not valid"

The unexpected exception is the following:

java.lang.NullPointerException

  at com.sas.analytics.eminer.visuals.Main.main(Main.java:732)

  at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

  at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source)

  at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source)

  at java.lang.reflect.Method.invoke(Unknown Source)

  at com.sun.javaws.Launcher.executeApplication(Unknown Source)

  at com.sun.javaws.Launcher.executeMainClass(Unknown Source)

  at com.sun.javaws.Launcher.doLaunchApp(Unknown Source)

  at com.sun.javaws.Launcher.run(Unknown Source)

  at java.lang.Thread.run(Unknown Source)

Please, could you help me to fix the problem?

Regards

Luis

Re: Java.lang.Null Pointer Exception

Check the needed java version in the SAS documentation fort this (on demand 13.2 using webstart).

The webstart approach is sensitive for the java-version and browser behavior on your machine.


For avoiding  this dependency it could be needed delivering a browser java in a virtualize machine environment.

This environment could run the java virtual machine Enterprise Miner is based on. (A matroeska approach)
