Perforce JViews Gantt Sample: Activity Chart and XML

Description

JViews Gantt provides the ilog.views.gantt.xml package. It is designed to serialize scheduling data contained in Gantt models into SDXL (Schedule Data eXchange Language) files. This sample shows how to use this package to serialize Gantt models associated with a Gantt Chart into SDXL files.

How to Use the Sample

To save the current Gantt data model to XML:
1. Select Save As in the File menu. The Save dialog box opens automatically in a directory containing sdxl.dtd.
2. Type the name of the file in the File Name text box.
3. clickSave.
To open an XML file and display its Gantt data model.
1. Select Open in the File menu.
2. Select a .sdxl file.
3. ClickOpen.

How to Run the Sample as an Application

This sample can be run as an application. The installation directory contains an executable JAR file, xml-gantt.jar, that allows you to execute the sample with a double click from a file browser. Note that if you are using Internet Explorer, you can open the installation directory and execute the JAR file from the browser. This technique may not work in other Web browsers.

Alternatively, you can run the sample application from the command line. First check that the Ant utility is properly configured. If not, see the instructions on how to configure Ant for Perforce JViews.

Then, go to the installation directory of the sample and type:

ant run

Topics Covered

Using the Gantt model XML readers and writers

Detailed Description

This sample shows how to use the default Gantt model readers and writers in the ilog.views.gantt.xml package. It uses the IlvGanttDocumentReader, IlvGanttDocumentWriter, and IlvGanttStreamWriter classes. All three classes are high-level, ready-to-use readers or writers.
This sample extends the Gantt Chart sample, found in the <installdir>/samples/ganttChart directory. It adds a File menu that allows you to:

Save the current Gantt model in an XML file.
Open an existing XML file and load the serialized Gantt model into memory.

A DTD file, sdxl.dtd, is used by this sample to define the XML file format. Please ensure that when you save a Gantt model to an XML file, this file is present in the directory where you create the XML file.
