Java

For the integration of ONLYOFFICE Document Builder into any application, the Java doctrenderer library is used.

Classes

The current application version contains four main classes:

Name	Description
CDocBuilder	Used by ONLYOFFICE Document Builder for the document file (text document, spreadsheet, presentation, form document, PDF) to be generated.
CDocBuilderContext	Used by ONLYOFFICE Document Builder for getting JS context for working.
CDocBuilderContextScope	The stack-allocated class which sets the execution context for all operations executed within a local scope.
CDocBuilderValue	Used by ONLYOFFICE Document Builder for getting the results of called JS commands. It represents a wrapper for a JS object.

JDK 8 and above is supported.

Example

Java

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 document = 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);

        document.call("InsertContent", content);

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

        CDocBuilder.dispose();
    }
}

.docbuilder

builder.SetTmpFolder("DocBuilderTemp")
builder.CreateFile("docx")
const oDocument = Api.GetDocument()
const oParagraph1 = Api.CreateParagraph()
oParagraph1.SetSpacingAfter(1000, false)
oParagraph1.AddText("Hello from Java!")
const oParagraph2 = Api.CreateParagraph()
oParagraph2.AddText("Goodbye!")
const aParagraphs = [oParagraph1, oParagraph2]
oDocument.InsertContent(aParagraphs)
builder.SaveFile("docx", "result.docx")
builder.CloseFile()
