Hi everyone,
I am a new user to cTAKES, and just downloaded cTAKES 4.0 based on
installation guide.
I also downloaded Java 9.0.4 SE Runtime Environment (I have limited
computer science background).
*Problem: *I am unable to load the AE
"AggregatePlainTextUMLSFASTProcessor", but "the
AggregatePlainTextProcessor" loaded fine.
*Error log:* SEVERE: Initialization of annotator class
"org.apache.ctakes.dictionary.lookup2.ae.DefaultJCasTermAnnotator" failed.
... Caused by "java.base/jdk.internal.loader.ClassLoaders$AppClassLoader
cannot be cast to java.base/java.net.URLClassLoader"
I have attached the log file. If anyone has experienced similar error,
please let me know?
Thanks!
Best Regards,
Queenie
