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(); }
}
