Hi, Sorry to hear of the startup troubles; I think they can be quickly solved. Here are some suggestions.
The bottom line - I think the directions were written assuming you have two Eclipse projects in your workspace, one for the uimaj-examples, and one for the uimaj-tools itself. This would be the case if you downloaded the source distribution, unzipped (or untarred) it, and then used the Eclipse Import to "import existing Maven projects". But there's a work around. Please read on... When you say you cannot run them, are you trying to run them via Eclipse (run menu), or the command line? It sounds like you may have downloaded the UIMA Java SDK "binary" package and unzipped or untarred it, is that correct? Or did you download the source code, import it into Eclipse, and "built" it? I'm guessing you may have done the "binary" package. In that case there are a couple of steps to do, described in the binary distribution's README - scroll down to the part about setting the Environment Variables JAVA_HOME and UIMA_HOME, and running UIMA_HOME/bin/adjustExamplesPaths.bat (or .sh if on linux). I know you said you set UIMA_HOME as an "Eclipse" variable, but did you also set it as an environment variable? If you're running from Eclipse, go to the run configuration ( menu -> run -> run configurations) and pick a tool, say for instance, the UIMA Document Analyzer, and click it once to "open" it. Then look at the "classpath" tab. On my installation, it shows under "User Entries" two projects: "uimaj-tools" and "uimaj-examples". I suspect you only have an Eclipse Project for "uimaj-examples", and are missing the one for uimaj-tools. You can fix this by clicking on "User Entries", and then on the right on "Add External Jars", and there add the uimaj-tools jar from the lib directory in the unzipped UIMA Binary distribution. If I've made wrong guesses about the details of your situation, please respond back with the corrected details :-) Good Luck! -Marshall On 5/22/2015 9:36 AM, Lothar Diefenbaker wrote: > Hello Everyone, > > I recently become involved in a project with Apache UIMA.
