Hi,
RapidMiner cannot find the TextProcessing extension and therefore replaces the Read Document operator with the dummy operator. Make sure to include the TextProcessing extension in your project.

hi,
When i use the read document procces in a java application i have the problem:
WARNING: Caught exception in concurrent execution of Read Document (Read Document): java.lang.StringIndexOutOfBoundsException: String index out of range: -1
java.lang.StringIndexOutOfBoundsException: String index out of range: -1.
I change the encoding to ansi,utf-8 but nothing.
Any suggestions??0 -
Hi,
do you have by chance selected "parallelize main process"? It looks like the Parallelize Processing extension has a problem there. You might want to try it without any parallelization to see if it works.
Apart from that, please post the full stack trace here.
