Hello,

i' m trying to create a web application which runs rapidminer. Locally, my web application is running perfectly but when i upload my application at openshift tomcat server i have problems because rapidminer doesn't load text processing extension. I'm using rapidminer 5.3 and rmx_text-5.3.2.jar .

Actually, i will show you my java code and server logs.
My java code



try {
String realPath1 = getServletContext().getRealPath("rapidminer/test1.xml");
    RapidMiner.setExecutionMode(ExecutionMode.COMMAND_LINE);
   
      RapidMiner.init();
      Process process = new Process(new File(realPath1));

    try {
       
      // perform process
      process.run();
  } catch (OperatorException e) { message= " error" +  e; e.printStackTrace(); } 
  }

    To get rid of the easy option first, where is your server looking for the extension?
