I made a Java application that classifies the data inside an excel file. Here's a snippet of the code.

            RapidMiner.setExecutionMode(RapidMiner.ExecutionMode.COMMAND_LINE);
            ProcessEntry pEntry = null;
            RepositoryManager.getInstance(null).addRepository(new LocalRepository("RMThesis", new File("Resources/TrendClass(70%)")));
            if(cbAlgo.getSelectedItem() == "k-NN"){
                RepositoryLocation location = new RepositoryLocation("//RMThesis/Apply Model (Oct Data)");
                pEntry = (ProcessEntry) location.locateEntry();
                RapidMiner.init();
                JOptionPane.showMessageDialog(null, "Location set", "Message", JOptionPane.INFORMATION_MESSAGE);
            }
            else if(cbAlgo.getSelectedItem() == "SVM"){
                RepositoryLocation location = new RepositoryLocation("//RMThesis/Apply Model (SVM)");
                pEntry = (ProcessEntry) location.locateEntry();
                RapidMiner.init();
            }
            else if(cbAlgo.getSelectedItem() == "Naive Bayes"){
                RepositoryLocation location = new RepositoryLocation("//RMThesis/Apply Model (NB)");
                pEntry = (ProcessEntry) location.locateEntry();
                RapidMiner.init();
            }
          if(pEntry instanceof ProcessEntry)
          {
                String processXML = pEntry.retrieveXML();
                Process myProcess = new Process(processXML);
               
                Operator op = myProcess.getOperator("Read Excel");
                op.setParameter(ExcelExampleSource.PARAMETER_EXCEL_FILE, selectedFile.getPath());         

                IOContainer ioResult = myProcess.run();
          }

I already added the rmx_text-ANY-5.3.2.jar in my library to be able to use text processing but still i have this error. I hope someone can help me :(

    Hi,

    RapidMiner itself needs to know about the text processing extension, so declare a dependency in your build.xml and make sure the text extension is in the plugin folder of RapidMiner.
    Note: Call RapidMiner.init(); right after setting the execution mode as this is the first thing you need to do before using any other functionality of RapidMiner.

    Regards,
    Marco

    Thanks for the reply :)

    Can you be so kind and show me the syntax on how to declare the dependency in my build.xml?

    Hi,

    you can add the following line to your build.xml to depend on the text processing extension 5.2: 

    <property name="extension.dependencies" value="rmx_text[5.2]" />
    If you are wondering how the value is defined, have a look at our marketplace here: http://marketplace.rapid-i.com/
    Then check the "product-id" for an extension, see here: http://marketplace.rapid-i.com/UpdateServer/faces/product_details.xhtml?productId=rmx_text

    Regards,
    Marco
