2. jbpm6 environment configuration 2.1. Down

Jbpm-distribution-6.1.0.CR1-installer-full.zip (403 m)

 

Include

Dashboard-builder-6.1.0.CR1.war 18 m

Jbpm-console-6.1.0.CR1.war (196 m)

Jboss-as-7.1.1.Final.zip 130 m

Jbpm-6.1.0.CR1-bin.zip 42 m

Org.drools.updatesite-6.1.0.CR1.zip 20 m

 

Jbpm-console is a web version. You can choose not to use the... dashboard-builder. It seems to be a Form builder... install Li Yizhen and install Ma 'an... give up ..

Eclipse 4.3

 

2.2. Install eclipse jbpm plugin

 

U: \ jbpm-installer \ liborg.drools.updatesite-6.1.0.CR1.zip (19 m)

Install by archi.zip

0. After restarting, you will find one more parameter in eclipse preference: jbpm. For example, it indicates that you have succeeded.

 

2.3. Set jbpm6_runtimes

U: \ jbpm-installer \ Lib \ jbpm-6.1.0.CR1-bin (41 m)

Open eclipse-> preferences. A dialog box is displayed, and "jbpm" is found in the text box ".

3. step 3 configure the installed jbpm runtimes path, click open, click the "add" button, name write: "jbpm6_runtimes", path: browse to the "jbpm-6.0.1.Final-bin" path, that is, it was just released to disk D.

 

3. Configure the sequential execution process 3.1. cretae demo prj run the automatically generated test code

 

Open eclipse, right-click the new jbpm Project, and enter a project name in the project name, for example, "testjbpm6". Then, finish the project (the runtime environment we configured will be used ).

It will automatically generate an instance for us. The processtest. Java file can run the sample. BPMN process file. Run the process. Java class directly, right-click Run as-> JUnit test, then the console will enter the "Hello World" Text

 

 

3.2. Create a new process BPMN File

New> jbpm> pbmn process> pkg1 package> New File bpmnati. BPMN...

 

Drag start, script task, and end nodes to connect them with squ flow lines...

 

 

 

3.3. Add the start and end controls 3.4. Add a script task control... process Desgin... opoen BPMN, then open prodesginer...

Like follow ..

 

3.5. Set the execution Java statement of the script task control ..

Note> rit key> property {panel},> can see action properry... enter Java statement ..

 

 

Set the action attribute system. Out. println ("Hello World attilax22") of the task node ");

3.6. Set the ID attribute of process: process2

 

3.7. Call the execution process function

The execution process requires two parameters: the path of the BPMN file and the ID of the process...

You need to create a knowledge base that contains the process definition.

You need to create a session to communicate with the process engine and the startup process.

Runtimemanager makes it easier for you to access ksession and task services.

 

Public static void main (string [] ARGs ){

Kiehelper = new kiehelper ();

Kiebase = kiehelper. addresource (

Resourcefactory. newclasspathresource ("pkg1/bpmnati. BPMN "))

. Build ();

Kiesession ksession = kiebase. newkiesession ();

Processinstance = ksession. startprocess ("process2 ");

4. Configure the if else branch structure of jbpm 4.1. Java code

If (task0 ())

Task1 ()

Else task2 ();

 

4.2. Add the Start Control and script task control task04.3. create a global variable (within the scope of the process file)

Task0> property> action> globale ::

// Define your globals here: e.g. Global java. util. List mylist

Global integer task0result

 

4.4. Set the return variable value of the task0 Control

 

Task0result = 3; // jeig haosyeo bcyi zayon... only a task can use... bnen cross task...

 

// Kcontext. setvariable ("task0result", 1 );

Kcontext. getknowledgeruntime (). setglobal ("task0result", new COM. sample. tif (). task0rztmeth ());

// Jeig nen cross task...

 

4.5. Add an if else Branch Control: Gateway diverge

Then configure the conditions... jump ..

Type: XOR

Constraints: To node1: Return task0result = 1;

To node2: Return task0result = 2;

 

4.6. Add two script task controls to execute task1 () & task2 (); 4.7. Add a gateway converge control pointing to the end control...

 

 

5. jbpm loop structure. Configuration 6. Other concept 6.1. Java and mvel

Jbpm currently supports two dialects: Java and mvel. Java actions should be effective Java code. Mvel actions can be expressed in the business scripting language mvel. Mvel accepts any valid Java code, but also provides support for nested parameter access (for example, person. Name, rather than person. getname (), and many other script improvements. Therefore, mvel expressions are more convenient for commercial users. For example, for an action, the name of the process variable of the printed person in the "requester" looks like this:

// Java Dialect System. Out. println (person. getname ());   // Mvel Dialect System. Out. println (person. Name );

 

6.2. jpdl is one of the Process Languages built on the jbpm framework.

. In jpdl, tasks, wait states, timers, and automatic processing are provided )... And intuitively describe the business process through graphic process definitions.

Jpdl can be deployed in any Java application environment, including javase application (swing/SWT) and javaee application (Application Server ).

 

 

 

 

6.3. Java Rule Engine-drools

Drools is a Java-based rule engine. It is open-source and can free complicated and variable rules from hard coding and store them in files as Rule scripts, this allows changes to rules to take effect immediately online without having to correct the code and restart the machine.
