Exception in thread "main" java.lang.Error: Unresolved compilation problem: LocalConverter cannot be resolved

Question

I am trying to convert Docx file to pdf file in java using documents4j 1.0.3.jar, but I can't to able to convert that. I saw some references, everyone suggesting to do in the maven project with pom file dependencies. we don't maven project, I want solution only in a java project with added jar files.

code :

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;
import com.documents4j.api.DocumentType;
import com.documents4j.api.IConverter;
import com.documents4j.job.LocalConverter;

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

    File inputWord = new File("/home/enad2/Downloads/Sample.docx");
    File outputFile = new File("/home/enad2/Desktop/Sample.pdf");
    try  {
        InputStream docxInputStream = new FileInputStream(inputWord);
        OutputStream outputStream = new FileOutputStream(outputFile);
        IConverter converter = LocalConverter.builder().build();
        converter.convert(docxInputStream).as(DocumentType.DOCX).to(outputStream)
        .as(DocumentType.PDF).execute();

        outputStream.close();
        System.out.println("success");
    } catch (Exception e) {
        e.printStackTrace();
    }
}

Answer 1

You can add a jar file in Eclipse by: right-clicking on the Project → Build Path → Configure Build Path. Under Libraries tab, click Add Jars or Add External JARs and give the Jar.

Answer 2

The class com.documents4j.job.LocalConverter is not in your classpath since you are getting the error you have to add documents4j-local jar you can get the jar here . Download the jar and add it to the classpath.

You might want to use maven outside your project just to create a shaded jar, or to gather all these deps for you so you can easily copy them.
