Java samples guide

Before you start​

For the samples to work correctly, make sure that two conditions are met:

  1. ONLYOFFICE Document Builder is installed. For more information visit installing page.
  2. The directory in which you are going to store the downloaded samples has general editing access to save files created by the Document Builder.

Hello world sample​

import docbuilder.*;

public class Program {
    public static void main(String[] args) {
        String resultPath = "result.docx";

        test(resultPath);

        System.gc();
    }

    public static void test(String resultPath) {
        CDocBuilder.initialize("");
        CDocBuilder builder = new CDocBuilder();
        builder.createFile(FileTypes.Document.DOCX);

        CDocBuilderContext context = builder.getContext();

        CDocBuilderValue global = context.getGlobal();

        CDocBuilderValue api = global.get("Api");
        CDocBuilderValue doc = api.call("GetDocument");
        CDocBuilderValue paragraph1 = api.call("CreateParagraph");

        paragraph1.call("SetSpacingAfter", 1000, false);
        paragraph1.call("AddText", "Hello from Java!");

        CDocBuilderValue paragraph2 = api.call("CreateParagraph");
        paragraph2.call("AddText", "Goodbye!");

        CDocBuilderValue[] paragraphs = { paragraph1, paragraph2 };
        CDocBuilderValue content = new CDocBuilderValue(paragraphs);

        doc.call("InsertContent", content);

        builder.saveFile(FileTypes.Document.DOCX, resultPath);
        builder.closeFile();

        CDocBuilder.dispose();
    }
}
note

JDK 8 or newer is required.

Save the code above as Program.java file in the SDK folder. Run the script:

javac -cp "docbuilder.jar" Program.java
java -cp "docbuilder.jar;." Program

Document will be created in the test directory.

Run other samples​

Clone a repository with the Document Builder samples from https://github.com/ONLYOFFICE/document-builder-samples. The created folder must have general editing access.

git clone https://github.com/ONLYOFFICE/document-builder-samples
cd document-builder-samples

The project folder includes the java folder with the Java samples. Each sample has its own folder with the Program.java program file.
