Subject RE: Trouble loading AE

Thanks, Bandeep. That seems to have solved that issue, but now when I try to load AE I get
an error message popup that states: "org.apache.uima.resource.ResourceInitializationException".
I'm not sure what this means? It only happens when I try to load the AEs that utilize UMLS.

Thanks in advance.

Hi Milena,

It looks like a classic example of Java version mismatch. One of the dependencies of cTakes
is Java 8
Please make sure you have JAVA SDK installed and not JRE. I have OpenJDK 8 running on my system
and cTakes runs fine on my system.

I have just installed cTakes and followed instructions in the 3.2 User Install Guide. However,
I am unable to load an AE. I have a UMLS user name and password, and have updated the appropriate
scripts as outlined in the User Guide, yet I get this error when trying to load any AE (even
the non-UMLS ones):

Exception in thread "AWT-EventQueue-0" java.lang.UnsupportedClassVersionError: org/apache/ctakes/dependency/parser/ae/ClearNLPDependencyParserAE

 I have double checked that I have the latest Java software. Any idea what could be causing
this error?

Thank you!
