Generate Document for each Business Process Diagram in Project using Open API

Doc. Composer is a build-in document builder in Visual Paradigm which allows user create professional looks document with fully customizable XML templates. With the Build from Scratch mode user can create customized XML template and drag & drop it into document editor for rendering documents. This process can be automated using Open API. In this document we will demonstrate how create plugin to automatic publish all business process diagrams in your project to Word document using your specified XML template.

Since the implementation of user interface of the sample plugin is not focus in this topic, therefore they will not be explained in details. We will focus on the section related to generating documents.

Prepare Default Content Block

First we have to prepare the default content block for holding the template we going to use.

// Retrieve default content block
public static IRDOOTemplate getBpdReportTemplate() {
  // Retrieve Doc. Composer in project
  IReportDiagramUIModel lReportDiagram = getBpdReport();
  if (lReportDiagram == null) {
    return null;
  IProject lProject = ApplicationManager.instance().getProjectManager().getProject();
  IReportDiagramDetails lDetails = (IReportDiagramDetails) lProject.getModelElementByAddress(lReportDiagram.getGenericXMLElementAddress());
  return lDetails.getRDOOTemplateByName(TEMPLATE_NAME);

If it not exist then we create one.

// Create content block
private boolean prepareReportTemplate() {

  IBusinessProcessDiagramUIModel[] lBpds = BpdsReportGenerator.collectBpds();
  if (lBpds.length == 0) {
        "Please open the project contains your BPD(s).", 
        "BPD not found", 
    return false;
  // Create document template model form user specified template XML
  BpdsReportGenerator.createBpdReportTemplate(_templateXmlField.getText(), lBpds, BpdReportTemplateDialog.this.getComponent());
  IRDOOTemplate lTemplate = BpdsReportGenerator.getBpdReportTemplate();
    if (lTemplate != null) {
  return lTemplate != null;

Specify Template for Content Block

Once the default content block is ready we can then set user specified template to content block.

//Use user specified template in content block

Generate Document for each BPD

Finally we walk through all BPDs in project to set the diagram ID into content block, and then output it to Word files.

  for (String lBpdId : lBpdIds) {
    _progressBar.setString("Generating... ("+lIndex+" of "+lBpdIds.length+")");
      // Retrieve the template model user specified, and specify the diagram ID into template
      IRDOOTemplate lTemplate = BpdsReportGenerator.getBpdReportTemplate();
    // Generate document to Word file.
    File lOutputFile = new File(lOutputDir, lBpdNames[lIndex]+".docx");
    lDocumentationManager.generateDocComposerWord(lReportDiagram, lOutputFile, BpdReportTemplateDialog.this._panel);
        "["+new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date())+"] " + 
            "Generated: " + lOutputFile.getAbsolutePath(), 
    _progressBar.setString("Generating... ("+(lIndex+1)+" of "+lBpdIds.length+")");
