RESTful Java Patterns and Best Practices

Unless otherwise indicated, only the German, French, English, and Japanese versions of these applications are supported. OpenOffice 2. Native formats supported by third-party applications requires development of setup files specific for the application Windows only. Include necessary files into your development project. If you are creating a client application using Java, include the necessary JAR files.

If you are using web services, ensure that you include the proxy files. This method needs information about the document to convert, including the file extension. After the file is converted to a PDF document, you can retrieve the results. Setting connection properties. Include client JAR files, such as adobe-generatepdf-client. The log file typically contains error or warning messages generated by the conversion request.

Summary of steps. Create a Microsoft. Address object by using the System. EndpointAddress constructor. However, specify? Create a System. Binding field. Cast the return value to BasicHttpBinding. Set the System. This value ensures that MTOM is used. After you create the service client, you can invoke the appropriate PDF creation operation. This operation needs information about the document to be converted, including the path to the target document.

Create a GeneratePdfServiceClient object by using its constructor and passing a ServiceClientFactory object that contains connection properties. To obtain the newly created PDF document, perform the following actions:. Form elements are not converted. After you create the service client, you can invoke the PDF export operation. Save the converted file. This section explains how to add support for additional native file formats.

It provides an overview of the interactions between the Generate PDF service and the native applications that this service uses to convert native file formats into PDF. The Generate PDF service converts native file formats by invoking the application associated with the file format and then interacting with the application to print the document using the default printer. The default printer must be set up as the Adobe PDF printer. This illustration shows the components and drivers involved with native application support.

It also mentions the XML grammars that influence the interactions. This document uses the term native application to indicate the application used to produce a native file format, such as Microsoft Word. AppMon is an enterprise component that interacts with a native application in the same way a user would navigate through the dialog boxes presented by that application.

The XML grammars used by AppMon to instruct an application, such as Microsoft Word, to open and print a file involve these sequential tasks:. AppMon uses standard Win32 APIs to interact with third-party applications in order to transfer UI events such as key-strokes and mouse clicks, which is useful to control these applications to produce PDF files from them.

Due to a limitation with these Win32 APIs, AppMon is not able to dispatch these UI events to some specific kinds of windows, such as floating menu-bars found in some applications such as TextPad , and certain kind of dialogs whose contents cannot be retrieved using the Win32 APIs.

It is easy to visually identify a floating menu-bar; however it might not be possible to identify the special types of dialogs just by visual inspection.

If WinID is able to extract the dialog contents such as the text, sub-windows, window class ID, and so on, then AppMon would also be able to do the same. File type settings associate file name extensions with the corresponding native applications. File type settings also specify native application settings used to print native files.

To change settings for an already supported native application, the system administrator sets the File Type Settings in the administration console. To add support for a new native file format, you must manually edit the file.

See Adding or modifying support for a native file format. Specifies interactions between the Generate PDF service and a native application. Such interactions usually direct the application to print a file to the Adobe PDF driver. The script contains instructions that direct the native application to open specific dialog boxes and that supply specific responses to fields and buttons in those dialog boxes.

The Generate PDF service includes script files for all supported native applications. You can modify these files using an XML editing application. To add support for a new native application, you must create a new script file. See Creating or modifying an additional dialog XML file for a native application.

Specifies how to respond to dialog boxes that are common to multiple applications. Such dialog boxes are generated by operating systems, helper applications such as PDFMaker , and drivers. The file that contains this information is appmon.

To add dialog box instructions for a new native application, see Creating or modifying an additional dialog XML file for a native application. Specifies overrides and additions to application-specific dialog box instructions. The section presents an example of such information. An example is appmon. Files of this type can be created and modified using an XML editing application. Important : You must create additional application-specific dialog box instructions for each native application your server will support.

Script XML files direct the Generate PDF service to navigate through application dialog boxes in the same way a user would navigate through the application dialog boxes.

Script XML files also direct the Generate PDF service to respond to dialog boxes by performing actions such as pressing buttons, selecting or deselecting check boxes, or selecting menu items. This section and the next section use different terminology for dialog boxes and the components they contain, depending on the perspective being described. Dialog box components are items such as buttons, fields, and combo boxes.

When this section and the next section describe dialog boxes and their components from the perspective of a user, terms such as dialog box , button , field , and combo box are used. When this section and the next section describe dialog boxes and their components from the perspective of their internal representation, the term window element is used.

The internal representation of window elements is a hierarchy, where each window element instance is identified by labels.

The window element instance also describes its physical characteristics and behavior. From an internal representation perspective, no such issue of behavior exists. For example, the internal representation of a dialog box looks similar to that of the components it contains, with the exception that the components are nested within the dialog box. These elements have names such as the dialog element and the window element.

This document uses a monospaced font to distinguish XML elements. This diagram shows the hierarchy of script and dialog XML. A script XML file conforms to the script. Similarly, a dialog XML file conforms to the dialogs. A script XML file specifies a series of steps that direct the native application to navigate to certain window elements and then supply responses to those elements. Most responses are text or keystrokes that correspond to the input a user would provide to a field, combo box, or button in the corresponding dialog box.

The steps in a script XML file are executed in order, without any opportunity for branching. In addition to steps being sequential, the instructions within a step are also executed in order. You must ensure that the steps and instructions reflect the order in which a user would perform those same steps. If an unexpected dialog box appears while executing a script step, the Generate PDF service searches the dialog XML files as described in the next section.

Running native applications displays different dialog boxes, which appear regardless of whether the native applications are in a visible or invisible mode. The dialog boxes can be generated by the operating system or by the application itself. When native applications are running under control of the Generate PDF service, system and native application dialog boxes are displayed in an invisible window.

The dialog XML files allow the Generate PDF service to respond to unprompted dialog boxes in a way that facilitates the conversion process. When the system or native application displays a dialog box that is not handled by the currently executing script XML file, the Generate PDF service searches the dialog XML files in this order, stopping when it finds a match:.

If the Generate PDF service finds a match for the dialog box, it dismisses it by sending it the keystroke or other action specified for the dialog box.

If the instructions for the dialog box specify an abort message, the Generate PDF service terminates the currently executing job and generates an error message.

Such an abort message would be specified in the abortMessage element in the script XML grammar. The currently executing job eventually times out.

You can then use the information in the log file to compose new instructions in the additional dialog XML file for the native application. This section describes the tasks you must perform to support other native file formats or to modify support for an already supported native file format. The dialog and script XML files require you to identify the window element dialog box, field, or other dialog component to which your dialog or script element is responding.

For example, after a script invokes a menu for a native application, the script must identify the window element on that menu to which keystrokes or an action are to be applied. You can easily identify a dialog box by the caption it displays in its title bar. The lower-level window elements can be identified through a variety of attributes, which are not obvious.

Additionally, each native application may identify its window element differently.
