"[SOLVED]:RapidMiner Integration with Java"

keshr3106

Hello,

I need to run a RapidMiner process in Java. Like explained in this link :http://stackoverflow.com/questions/15834182/integration-of-rapidminer-in-java-application,

import com.rapidminer.Process;
import com.rapidminer.RapidMiner;
import com.rapidminer.operator.Operator;
import com.rapidminer.operator.OperatorException;
import com.rapidminer.operator.io.ExcelExampleSource;
import com.rapidminer.tools.XMLException;
import java.io.File;
import java.io.IOException;
import java.lang.Object;

public class ReadRapidminerProcess {
public static void main(String[] args) {
try {

RapidMiner.setExecutionMode(RapidMiner.ExecutionMode.COMMAND_LINE);
RapidMiner.init();

Process process = new Process(new File("C:\\Users\\Keshav\\.RapidMiner5\\repositories\\Local Repository\\lsvmtest.rmp"));
process.run();

} catch (IOException | XMLException | OperatorException ex) {
ex.printStackTrace();
}
}
}

I run the above code. The code compiled but gave following error during its run:

PS: The amount of errors displayed was very large - due to the space constraint of 20,000 characters,I pasted only a part of the error message.

Hi,

disable assertions, they are not being maintained and will cause useless errors.

Hello,

I disabled assertions and I still get some errors though it has reduced.

What changes must I make to the code? Where am I going wrong? Please help.

Update:
After disabling assertions, I set right the rapidminer.home error by adding this line of code:

System.setProperty(“rapidminer。家”、“C: \\Program Files (x86)\\Rapid-I\\RapidMiner5");

Now, the following error alone exists:

UPDATE:
Made some modifications to the code.

public class ReadRapidminerProcess {
public static void main(String[] args) {
try {

RapidMiner.setExecutionMode(RapidMiner.ExecutionMode.COMMAND_LINE);
System.setProperty(“rapidminer。家”、“C: \\Program Files (x86)\\Rapid-I\\RapidMiner5");
RapidMiner.init();
RepositoryLocation loc = new RepositoryLocation("//Local Repository/linsvmtest");
IOObjectEntry entry = (IOObjectEntry) loc.locateEntry();
Process process = new Process(new File("C:\\Users\\Keshav\\.RapidMiner5\\repositories\\Local Repository\\linsvmtest.rmp"));
process.run();

}
catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (XMLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (OperatorException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (RepositoryException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

The previous 'Process is not associated with a repository.' error is set right but I get the following error:

Any help on how to deal with this?

Hi,

you are doing the following:

IOObjectEntry entry = (IOObjectEntry) loc.locateEntry();

however when you call locateEntry() on a repository location where a process lies, you will recieve a SimpleProcessEntry instead. This is why you are getting the ClassCastException.

Regards,
Marco

keshr3106

Okay...can you please tell what change in the code should I make ?

Hi,

you can use the following snippet to load a process from a known repository and location:

Repository repo = RepositoryManager.getInstance(null).getRepository("Local Repository");
RepositoryProcessLocation processLocation = new RepositoryProcessLocation(new RepositoryLocation(repo.getLocation(), "nameOfMyProcess"));
Process process = processLocation.load(null);
process.run();

Note that you can load processes from other sources as well, e.g. a File or the XML string representation.

Marco

然而,我无法编译它。(drjava)

Compiler Output:

Can you please tell me what should I import to remove this error? Where is the class Repository found?

Thank you very much for your prompt replies!

Hi,

Repository is an interface in the package com.rapidminer.repository in the main RapidMiner Studio project.

Hello,

It works properly now.I am now able to successfully integrate RapidMiner and Java!

Thank you very much for your help!

Is there any way to get the JAR? I am already scouring the net and could not obtain it.
