Oracle JDeveloper: Is this IDE dead? Are there new releases?

Some weeks ago i read the Java Magazine (http://www.javamagazine.mozaicreader.com)

 

They report from a survay taken place in 2018 about Java. One of the questions was which application server do you use in production:

This was not really amazing.
But the question about the IDE gave a really surprising result:

More developers use IntelliJ than Eclipse?

Not really surprising was the usage of Oracle's JDeveloper: Only 1% of the developers use this tool.

You have to keep in mind, that with using Oracle's SOA Suite / BPEL / ESB you are forced to use JDeveloper - which means this SOA stuff is not used by many people out there.

If you take a look on the Oracle homepage you will find:

The last version was released in august 2017 - this does look like living software.

For architects and consultants JDeveloper can be very useful because it has a very nice visualization of XSDs and XSLTs (Take a look here). So hopefully JDeveloper will stay alive...

Oracle SOA Suite 12c: How to deploy a BPEL onto a weblogic server

After you have created your BPEL inside Jdeveloper, you have to add an application server inside jdev:

 And here we go:

Then go to the applications view:

And after the deployment check via Application Server view, if the BPEL version was deployed:

Oracle SOA Suite 12c: Invoking a BPEL process via Jdeveloper

After you deployed a BPEL process to your application server open the application server view in Jdeveloper:

 Open the BPEL inside the Application Server view:

 Do a right click on the BPEL process and select "Test Web Service":

 This will open the HTTP Analyzer:

 Fill in your XML input and click "Send Request". After that you will see:

Very nice are the options via the tab at the bottom:

• SOAP Strucutre
• HTTP Content
• REST Structure
• Hex Content
• Raw Message

 Here as example the output of the option "Raw Message":

Oracle SOA Suite developer IDE: Creating a BPEL process (101HelloWorld)

After downloading and installing jdeveloper SOA Suite edition here a short 101 for building a BPEL process. (Nearly 10 years ago i posted the lost collaxa tutorials: 101.HelloWorld. All of these tutorials can be found here.)

First you have to start your jdeveloper (Middleware/Oracle_Home/jdeveloper/jdev/bin/jdev) and choose "All Features":

 

Then create a new application:

and choose SOA application:

and walk through the application wizard:

application wizard 2/3

application wizard 3/3

application wizard 3.1/3 (create BPEL process)

and here we are:

a right click onto the blue BPELProcess1 icon and "edit" opens the BPEL process:

On the right hand to this process you can find the components palette:

Now drag and drop the assign icon between the receiveInput and replyOutput node:

A right click to the Assign node and choosing "edit" will open up this dialog:

You can do this mapping via drag and drop:

and finished!

A nice feature of jdeveloper is the "History" tab, where you can compare changes within the XML:

Next posting i will show, how you can run this BPEL process within the jdeveloper builtin weblogic server.

Oracle BPM: How to use start and end events

For modelling a process you have to configure your Jdeveloper 11g like shown in this posting. Then you can create easliy a process like this one:

[The behaviour of the tool palette is a little bit weird, because you can not use drag&drop. You have to click an item and then move the mouse inside the graph. Then the item is beneath the mouse cursor and you can place it with a second click.]

The start event can be changed via right mouse click:

[The start event with the envelope is called "message start event"]

Here an excerpt from the official documentation about the start events:

The none start event is used when no instance trigger is defined. Process analysts can use the none start event as a placeholder when the necessary start event of a process is unknown or is defined and implemented later by process developers. None start events are also used to specify the beginning of a process where the process instance is created by another flow object. Although the none start event does not trigger the creation of a process instance, it is required when triggering a process instance using the following flow objects:

• Receive task. The receive task must have the Create Instance property set to true.
• User task implemented with the initiator pattern

The message start event triggers a process instance when a message is received. This message can be sent from another BPMN or BPEL process or from a service. Messages are types of data used for of exchanging information between processes. Just as data objects are used to define the data used within a project, messages are used to define the data used between processes or between a process and a service.
You can exposed a BPMN process as service which enables other processes and applications to invoke the process. To expose a process as a service, your process must begin with a message start event.

The signal start event is similar to a message start event in that it is based on communication from another process or service. However, the message start event responds to a message sent to a specific process. In contrast, the signal start event is a response to a signal broadcast to multiple processes. Signals can be broadcast from a BPMN process using the signal throw event. Using a combination of signal throw and signal start events, you can invoke multiple processes simultaneously.

The timer start event triggers the creation of a process instance based on a specific time condition. You can configure the timer start event to trigger a process instance based on the following:

• A specific date and time. For example, a process could be triggered on December 31, at 11:59 PM.
• A recurring interval. For example, a process could be triggered every 10 hours, 5 minutes, 32 seconds.

The following end events can be used:

• None end event
  like start event
  
• Error end event
  Errors end events are normally used with the error boundary event. The error
  boundary event is used to alter the process flow based on a specific error. This flow usually ends using an error end event.
  
• Message end event
  like start event
  
• Terminate end event
  The terminate end event is used to immediately terminate a process. When a terminate end event is reached, the process ends immediately. There is no error handling or additional clean up performed.
  

BPM on Linux...

Running jdeveloper on Linux is not really a problem. Just unzip the tarball (<11g) or run the installer (11g +) and start with ./jdev.
Jdeveloper 11g starts on Linux but after installing the BPM functionality i got:

With this error messages the bpm.modeler does not work...
Does anybody know, how to get around this problem? (On Windows there are no problems -> BPM-modellers do not use Linux?!)

Oracle BPM 11g: Missing BPM Studio Components in Jdeveloper 11g

Oracle announced Business Process Management Suite 11g on June 14th 2010:

• A component of Oracle Fusion Middleware 11g, Oracle Business Process Management Suite 11g is the industry’s most complete, open and integrated Business Process Management (BPM) solution.

• Oracle Business Process Management Suite 11g supports all types of processes with a new unified process foundation, user-centric design and social BPM capabilities.

• Oracle Business Process Management Suite 11g includes a native implementation of BPMN 2.0.

So let's take a look at BPM homepage. There you can find a link "getting started". But on the "getting started" page there is a link "Get started with BPM Suite 10g".
Ok - you want 11g you should start with 10g and no quick link how to start the studio...

Next try: Start with the BPM download page. This sounds better:

• JDeveloper: Download JDeveloper 11.1.1.3.0 (BPM Studio) from the FMW download page. Look for JDeveloper and Application Development Framework in the Required Addition Software section.

• SOA and BPM Extension for JDeveloper: Install the SOA and BPM Extension using the JDeveloper Update Center. From the JDeveloper menu choose Help > Check for Updates. In the Update Wizard, select Search Update Centers and ensure Oracle Fusion Middleware Products is checked ( screenshot). Then ensure that Oracle SOA Composite Editor is checked ( screenshot, your version may not match the screenshot exactly). The SOA and BPM Extension is approximately 200 MB each.

But the screenshots are a redirects to the BPM Homepage....

To save your time, here a quick start, how to get the BPM Studio.

First download JDeveloper 11g (11.1.1.3.0), unzip it and run jdeveloper:

Then open "Check for Updates" inside the "help" menu.

After that follow the Update Wizard like shown in the next pictures:

At this step you have to provide your Oracle account credentials.

Finished!!!

Now you can choose "New Appliation"

and here we go:

That's all...
