-code for document Level 
Document.setOpenAction(JavascriptAction)
-code for Page Level 
document.getPages().get_Item(2).getActions().setOnOpen(JavascriptAction)
document.getPages().get_Item(2).getActions().setOnClose(JavascriptAction)


Code Snippet for DOM, examples to insert JavaScript into different place:

String path = "D:\\";
		String fileOut = path+ "JavaScript.pdf";
	        IDocument document = null;
	        try 
	        {
	            document = new Document();
	            document.getPages().add();
	            document.getPages().add();
	            
//Adding JavaScript at Document Level
//Instantiate JavascriptAction with desried JavaScript statement
	          JavascriptAction javaScript=new JavascriptAction("this.print({bUI:true,bSilent:false,bShrinkToFit:true});");

//Assigne JavascriptAction object to desired action of Document
	          document.setOpenAction(javaScript);
	          document.setOpenAction(new JavascriptAction("app.alert('Hello PDF')"));
	          
//Adding JavaScript at Page Level
	          document.getActions().setBeforeClosing(new JavascriptAction("app.alert('document is closing')"));
	          
	          document.getPages().get_Item(1).getActions().setOnOpen(new JavascriptAction("app.alert('page 1 is opened')"));	          
	          document.getPages().get_Item(2).getActions().setOnOpen(new JavascriptAction("app.alert('page 2 is opened')"));
	          document.getPages().get_Item(2).getActions().setOnClose(new JavascriptAction("app.alert('page 2 is closed')"));
	          
//after printing
	          document.getActions().setAfterPrinting(new JavascriptAction("app.alert('File was printed')"));
//after saving
	          document.getActions().setAfterSaving(new JavascriptAction("app.alert('File was Saved')"));
	            document.save(fileOut);
	        }
	        finally { if (document != null) document.dispose(); document = null;}

Code Snippet for old generator:

String path = "D:\\";
		//Instantiate a PDF Object
		Pdf pdf = new Pdf();
		pdf.setJavaScripts(new JavaScripts());

		//Call the Add method and JavaScript statement as an argument, to show alert
		pdf.getJavaScripts().add("app.alert(\"hello world\");");

		FileOutputStream out = new FileOutputStream(new File(path+"test.pdf"));

		//Save Pdf Document
		pdf.save(out);

Example to add formating code and value validation:

		initLicense();
		String path = "D:\\Temp\\";	
		Document doc = new Document(path+"PdfWithAcroForm.pdf");
		TextBoxField text = (TextBoxField)doc.getForm().get_Item("textField");
		text.getActions().setOnFormat (new JavascriptAction("AFNumber_Format(2, 0, 0, \"\", true);"));
		text.getActions().setOnModifyCharacter ( new JavascriptAction("AFNumber_Keystroke(2, 0, 0, \"\", true);"));
		text.getActions().setOnValidate ( new JavascriptAction("AFRange_Validate(true, 1, true, 100);"));
		text.setValue  ("100");
		doc.save(path+"formatted.pdf");

PDFNEWJAVA-34337 Memory leak issue

If the client has completed the work with our library and wants to clear the memory from different static instances,
to make free the maximum memory for other processes, the following line should be executed: 
com.aspose.pdf.MemoryCleaner.clear ();PDFNEWJAVA-34065 HTML to PDF - Add a setting to not pull down remote resources

Realizing ResurseLoadingStrategi object at its discretion can perform different actions with remote resources. 
For example, to ignore the resources specific addresses:

    String inHtml = "D:\\Temp\\simple.html";
    String outPdf = "D:\\Temp\\output.pdf";
    
    HtmlLoadOptions options = new HtmlLoadOptions();
    options.setUseNewConversionEngine (true);
    options.CustomLoaderOfExternalResources = new ResourceLoadingStrategy() 
    {	
	    
	    public ResourceLoadingResult invoke(String resourceURI) 
	    {
		//Creating clear template resource for replacing: 
		LoadOptions.ResourceLoadingResult res = new LoadOptions.ResourceLoadingResult(new byte[] {});

	        // return empty byte array in case i.imgur.com server
	        if (resourceURI.contains("i.imgur.com"))
	        {
	            return res;
	        }
	        else
	        {
	            // process resources with default resource loader
	            res.LoadingCancelled = true;
	            return res;
	        }
	    }
    	};
    	
    // Do conversion    
    Document pdfDocument = new Document(inHtml, options);
    pdfDocument.save(outPdf);
