"[SOLVED] Error: Content is not allowed in prolog"

Hello,

I just started to try to implement RapidMiner into my own application. To make it easier for me I use Jython instead of Java,
which makes the code quite small: 

import com.rapidminer.RapidMiner as RapidMiner
import com.rapidminer.Process as Process
import com.rapidminer.RapidMiner.ExecutionMode as ExecutionMode

RapidMiner.setExecutionMode(ExecutionMode.COMMAND_LINE);
RapidMiner.init()
process = Process('D:/RapidMinerRepository/PolynomOptimierung.rmp')
result = process.run()

print result
On running it i get a problem in the Process-line: 

Dec 8, 2011 7:56:26 AM com.rapid_i.Launcher ensureRapidMinerHomeSet
...
[Fatal Error] :1:1: Content is not allowed in prolog.

com.rapidminer.tools.XMLException: com.rapidminer.tools.XMLException: Cannot parse document: Content is not allowed in prolog.
The workflow works well in the GUI and in the forum I didn't find any solution, so how to fix it?

    Solution Accepted

    This saved my day.
    The files was sored as UTF-8. SImply converted to ANSI solved the issue.

     

    Thnx,

    Hi,
    please open your .rpm file with a text editor and check if there is any other character before the "<?xml..." part.
    If so remove it and try to run your application again. If there is no other character it has to be an encoding problem.
    Try to save the .rpm file with another enconding.

    Regards,
    Nils

    Checkign the XML was the first thing I did and it was OK. Meanwhile I added some Java XML-parsing and this works fine,
    if I use "UTF-8" but fails with the same error by using "UTF-16": 

    # import necessary libraries
    import com.rapidminer.RapidMiner as RapidMiner
    import com.rapidminer.Process as Process
    import com.rapidminer.RapidMiner.ExecutionMode as ExecutionMode
    import time

    # start up rapidminer
    start = time.time()
    RapidMiner.setExecutionMode(ExecutionMode.COMMAND_LINE)
    RapidMiner.init()
    print "init done (%.1f sec)...\n" % (time.time()-start)

    # check wether Java can parse the XML file
    from java.io import FileInputStream
    from javax.xml.transform.stream import StreamSource
    from javax.xml.transform.stream import StreamResult
    from javax.xml.parsers import DocumentBuilderFactory

    factory  = DocumentBuilderFactory.newInstance() 
    builder  = factory.newDocumentBuilder()
    input    = FileInputStream('D:/RapidMinerRepository/myprocess.xml') 
    document = builder.parse(input)
    print 'First node is:',document.getDocumentElement().getNodeName()
    print "Java is done ...\n"

    # load the XML workflow for parsing and processing
    process = Process('D:/RapidMinerRepository/myprocess.xml')
    print "process loaded ...\n"

    # process workflow
    result = process.run()
    print "run finished ...\n"

    # print result information
    print "Result is:\n",result,'\n'
    Process(...) fails with both "UTF-8" and "UTF-16". Which coding I can test instead?

    Meanwihle I testes also "ISO-8895-1" and "windows-1252".

    The Java XML parser took both, Process(...) took none.

    Just to mention it: I'm working on Windows 7 64-bit and the Jython/Java version is also 64-bit, RapidMiner is "5.1.014" 64-bit.

    Here is the Java version, to be sure that it is not a problem of Jython (in fact: it isn't !): 

    package jrapidminer;

    import com.rapidminer.RapidMiner;
    import com.rapidminer.RapidMiner.ExecutionMode;
    import com.rapidminer.Process;

    public class jRapidMiner
    {

        public static void main(String[] args)
        {
            String rapidMinerHome = "C:/Program Files/Rapid-I/RapidMiner5/";
            System.setProperty("rapidminer.home", rapidMinerHome);
            RapidMiner.setExecutionMode(ExecutionMode.COMMAND_LINE);
            RapidMiner.init();

            try
            {
                String workflow = "D:/RapidMinerRepository/myprocess.xml";
                Process process = new Process(workflow);

                process.run();
            } catch (Exception e) {
            }
        }
    }
    and here is the output after execution: 

    run:

    Meanwhile I tested the posted Java code on Windows XP with RapidMiner 5.0 with a different workflow.
    The error message is the same. So either I always install my software with the wrong configuration or
    there is a basic error in the Java code ?!

    Now I got a little closer to the problem!

    I generated manually a new file with the only content: 
    <?xml version="1.0" encoding="UTF-8"?>
    The result: 

    ...
    [Fatal Error] :1:1: Content is not allowed in prolog.
    It seems that the error message is not appropriate to the error!

    ARRRGGGHHHH  ;D :( :-\

    Sometimes I really wonder if someone really reads the posts or not!

    Here is the quite simple solution of the quite stupid error:

    original code 
    Process process = new Process(workflowPath);
    corrected code 
    Process process = new Process(new File(workflowPath));
    Tomorrow I will send working code for the Jython version (for those who are interested).
    Extended: See http://rapid-i.com/rapidforum/index.php/topic,4408.0.html

    Best regards, Michael

    Uh, that really was quit simple. Maybe too simple i haven't seen it either  :o
    But i'm glad you solved it!

    Cheers,
