JODConverter telling me office manager is required in order to build a converter

Question

I'm trying to get JODConverter to work on Window 10 with Jdk 1.8.0_144. As you can see from the code I thought it might be a timing issue hence the delay. As you can see JODConverter thinks the OfficeManager is running. I'm using the follow code:

import java.io.File;
import org.jodconverter.JodConverter;
import org.jodconverter.office.LocalOfficeManager;
import org.jodconverter.office.OfficeException;
import org.jodconverter.office.OfficeManager;
import org.jodconverter.office.OfficeUtils;
import org.jodconverter.process.ProcessManager;

public class JodConverterTest {

    public static void main(String[] args) throws OfficeException, InterruptedException {

        OfficeManager officeManager
                = LocalOfficeManager.builder()
                        .officeHome("C:\\Program Files\\LibreOffice")
                        .portNumbers(2372)
                        .build();
        officeManager.start();

        File inputFile = new File("c:\\test\\rtf.rtf");
        File outputFile = new File("c:\\test\\rtf.pdf");

        try {

            System.out.println("officeManager.isRunning()="+officeManager.isRunning());
            Thread.sleep(10000);
            System.out.println("officeManager.isRunning()="+officeManager.isRunning());
            JodConverter.convert(inputFile).to(outputFile).execute();
        } finally {
            // Stop the office process
            OfficeUtils.stopQuietly(officeManager);
        }
    }
}

I get the following error when I run it:-

officeManager.isRunning()=true
officeManager.isRunning()=true
Exception in thread "main" java.lang.IllegalStateException: An office manager is required in order to build a converter.

BUILD FAILURE

Things I've tried:- - Changing the port number - Researching to see if I can find the classpath of the java Process Manager and adding the following but I couldn't find the classpath of the ProcessManager as I don't really know much about that:- .processManager("com.example.foo.CustomProcessManager") - also wondered whether it is something to do with running via Netbeans?

Here is the applicable maven dependency:-

        <dependency>
            <groupId>org.jodconverter</groupId>
            <artifactId>jodconverter-local</artifactId>
            <version>4.1.1</version>
        </dependency>

I've installed Libre (fresh install) in C:\Program Files\LibreOffice

Answer 1

Yes, this is my fault. The JODConverter documentation needs some major improvements. I created the static JodConverter.convert methods to ease the interaction with the jodconverter libraries, but there is no place in the documentation where I clearly state that this static class will use an office manager that would have been created as the default manager for all document converters.

This is done using the "install" function while creating an office manager.

So I thank you for being such a smart coder that figured it out, this stackoverflow post will help many developers for sure!!

Answer 2

Got it to work. Here is a solution:-

package ZPlaying;

import java.io.File;
import org.jodconverter.JodConverter;
import org.jodconverter.office.LocalOfficeManager;
import org.jodconverter.office.OfficeException;
import org.jodconverter.office.OfficeManager;
import org.jodconverter.office.OfficeUtils;

public class JodConverterTest {

    public static void main(String[] args) throws OfficeException, InterruptedException {
        OfficeManager officeManager = LocalOfficeManager.builder()
                .install()
                .officeHome("C:\\Program Files\\LibreOffice")
                .build();
        File inputFile = new File("c:\\test\\rtf.rtf");
        File outputFile = new File("c:\\test\\rtf.pdf");
        try {
            // Start an office process and connect to the started instance (on port 2002).
            officeManager.start();
            // Convert
            JodConverter
                    .convert(inputFile)
                    .to(outputFile)
                    .execute();
        } finally {
            // Stop the office process
            OfficeUtils.stopQuietly(officeManager);
        }
    }
