"[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:
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:
On running it i get a problem in the Process-line:
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
The workflow works well in the GUI and in the forum I didn't find any solution, so how to fix it?

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":
if I use "UTF-8" but fails with the same error by using "UTF-16":
Process(...) fails with both "UTF-8" and "UTF-16". Which coding I can test instead?
# import necessary libraries

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)

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 !):
and here is the output after execution:
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) {
}
}
}
Finally the XML:

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 ?!
Here is the XML:

Now I got a little closer to the problem!
I generated manually a new file with the only content:

Sometimes I really wonder if someone really reads the posts or not!
Here is the quite simple solution of the quite stupid error:

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).

Thnx,
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
