JBoss jbpm practice series (II)-configuration and use of the jbpm designer

This article undertakes the previous article "JBoss Jbpm Practice series (1) --- installation and configuration (Tomcat 6.0 + MySQL 5.1) Jbpm Configure and use the designer.

 

JBossJbpmDesigner official JBossJbpmYou can download the free Eclipse plug-in.JbpmKit (Jpdl suite), Which contains JBossJbpmAll components. The latest version is3.2.3,:

Http://www.jboss.org/jbossjbpm/jbpm_downloads/

 

Before you begin, prepare the following software products:

1.Jbpm-Jpdl-3.2.3. Zip

2. Eclipse3.3(Or3. 4) for J2EE developer

3. JDK 1.5 or later

 

 

1. Install JDK and eclipse. First download JDK and eclipse,

JDK: http://java.sun.com/

Eclipse: http://www.eclipse.org/downloads/download.php? File =/technology/EPP/downloads/release/Ganymede/R/eclipse-jee-ganymede-win32.zip

After JDK is installed, set the system environment variable java_home. For more information, see the official documentation. Eclipse can be used after decompression.

Note: By JBossJbpmOfficial Document, JBossJbpmDesigner requires eclipse3.3, Now eclipse3. 4 It has been around for more than half a month and can be found in eclipse3. 4. Eclipse is recommended.3.3. The local machine has been upgraded3. 4, so this article uses eclipse3. 4

 

2. Download jpdl suite3.2.3GetJbpm-Jpdl-3.2.3. ZIP file, decompress it. Here, we suppose to decompress it to: D :\Jbpm-Jpdl-3.2.3The main directory structure is as follows:

3. Install JBoss in eclipseJbpmDesigner plug-in

3. 1 install the plug-in

Start eclipse and go to help => Software Updates... => Select the "available soft ware" tab and click "add site ..." => Local... => Locate "D :\Jbpm-Jpdl-3.2.3\ Designer \ eclipse click OK and select Org.Jbpm. Gd, jpdl. feature "click" Install ", and the rest will not be awkward. After the installation is complete, let eclipse restart automatically.

 

3.2Configure plug-ins

View JBoss in window => preferencesJbpmItem, click expand, select rutime location, and click Add to locate D :\Jbpm-Jpdl-3.2.3The name can be obtained at will.Jbpm-Jpdl-3.2.3And then return to the runtime location to selectJbpm-Jpdl-3.2.3Click OK to complete the configuration.

 

 

4. Verify Installation

After completing the preceding operations, you can create a JBossJbpmProject. In eclipse, perform the following operations: file => New => the project has a "JBoss"Jbpm"Click to expand and select" process project "=> enter the project name (here: firstflow) => finish

 

Now you can start your JBossJbpmNow. The new project firstflow has provided a simple process definition example to open src/main/jpdl/simple/processdifinition. XML shows the graphic interface of the process definition in the editing area on the right. The designer is on the left. All GUI designers have the same usage. You can use them by dragging them. If you have done GUI development in JBuilder, this is very simple (there is no difficulty here ), you can also write code in source to define your process. GPD under src/main/jpdl/simple. XML is used to locate the layout of your graphic design component. You don't need to ignore it. In addition, select Show grid in the eclipse menu view, your designer will display the positioning grid, which will make the components more beautiful; processimage.jpg under src/main/jpdl/simple is the result image of the process definition you have drawn. As you can see, you only need to operate processdifinition. XML to define your process.

 

With examples, it is much easier. If we want to establish a process, right-click src/main/jpdl In the Eclipse project tree and choose new => Other => Find JBoss.JbpmAfter expansion, select process difinition => next => input process name (fisrtflow here) => finish. OK. Now you can define your own process.

 

After the process is defined, you can create a unit test in src/test to test your code. There are some examples available. After everything is done, you can deploy your process.

You can :\Jbpm-Jpdl-3.2.3\ Examples find various demos. These official examples are more authentic than other places. Please read:Jbpm-Jpdl-suite-3.2.3\Jbpm-Jpdl-3.2.3\ Examples \ readme.html.
