I have been struggling for hours now trying to install Tess4J. I tried it via maven and manually and I always get the same result.
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

This is when I use version 5.2.1.
When I install version 4.2.1 i get another error.
java.lang.NullPointerException: Cannot invoke "net.sourceforge.tess4j.TessAPI.TessBaseAPIDelete(net.sourceforge.tess4j.ITessAPI$TessBaseAPI)" because "this.api" is null
What is the problem with my installation?
