Is it possible to call BPMN process through java.

HI All,
Is it possible to call a BPMN process through a java. Please share your thoughts on this.
Thanks
Parker.

Check this API:
http://download.oracle.com/docs/cd/E17904_01/apirefs.1111/e10659/oracle/soa/management/facade/package-summary.html
Check mostly the class Composite, you can access a process with it (and even its instances).

How to call BPM process from Java

Hi All,
Can anybody help how to call a BPMN process from java.Please give any sample exaple on this.
Thanks,
Ganesh

For 11g BPM please look at this post. Re: Getting while running the BPEL process from java
It references an ATeam example app that can start processes from a web client. But the Java APIs are described too.

Implement callback for an asynchronous BPEL process through Java

Hi ,
I am trying to implement a callback functionality for an asynchronous BPEL process through java.
I found the code in the samples folder of SOA suite installation folder .
<SOA_HOME>\bpel\samples\tutorials\102.InvokingProcesses\rmi\com\otn\samples\async.
There is an AsyncInstanceWatchdog object which registers a callback object(in this case an object of AsyncCallbackImpl class) for a specific CONVERSATION_ID.
String convId = GUIDGenerator.generateGUID();
nm.setProperty(NormalizedMessage.CONVERSATION_ID, convId);
deliveryService.post(proc_name, "initiate", nm);
// register the callback
watchdog.registerAsyncCallback(convId, testAsyncHandler,
locator.getDomainAuth());
// start it
watchdog.start();
There is no problem till the last line. But once the BPEL process returns the control( does a callback), it throws the following error.
May 25, 2010 3:36:06 PM oracle.j2ee.rmi.RMIMessages EXCEPTION_ORIGINATES_FROM_THE_REMOTE_SERVER
WARNING: Exception returned by remote server: {0}
ORABPEL-02118
Variant not found.
The variant "output" has not been declared in the current scope. All variants must be declared in the scope before being accessed.
Please check that the variant "output" is properly declared; otherwise there may be a misspelling in the name of the variant.
at com.collaxa.cube.engine.core.Scope.getVariantRV(Scope.java:535)
at com.collaxa.cube.engine.CubeEngine.getFieldValue(CubeEngine.java:2668)
For your reference the variable output is declared in the definition of AsyncCallbackImpl (which implements the IAsyncInstanceCallback interface).
There are 2 methods defined in the AsyncCallbackImpl class.
public void onResult(Map pResultMessage) {
System.out.println("called back! ");
Iterator iTest = pResultMessage.keySet().iterator();
while (iTest.hasNext()) {
String key = (String)iTest.next();
System.out.println(XMLHelper.elementToString((Element)pResultMessage.get(key)));
public String getVariableName() {
return "output";
The variable name is same given in the sample code. And the BPEL process returns variable named output. So the name should not be a problem.
Is it because of the scope of the variable.. If so, how do I change it.
Any help would be appreciated.

Solved it by some googling .... :)
Here is the link:-
[http://abhishek-soablog.blogspot.com/2008/09/orabpel-02118.html]
or
[http://beautifulwaste.blogspot.com/2008/04/calling-asynchronous-bpel-process.html]
Both gives the same solution..
In pre 10.1.3.3 release the default behaviour were to keep global variable information along with the instance information for completed BPEL processes.
In 10.1.3.3 or later, this behaviour changed for performance reasons so that the default behaviour is now, not to keep any global variables for a BPEL process once the BPEL process has completed.
You can configure this behaviour on a process level basis by using the parameter keepGlobalVariables in the bpel.xml file for the specific process:
<BPELSuitcase>
<BPELProcess src=".........." id="...........">
<configurations>
<property name="keepGlobalVariables">true</property>
</configurations>
</BPELProcess>
</BPELSuitcase>

There are 2 options for things like this:
1) Use Runtime.exec() to execute some command or application and parse the input from it.
2) Write some native code and use JNI to call it.

What is the best way to call SSH commands through Java technologies

What is the best way to call SSH commands through Java technologies

I don't think you can specify the password at the prompt using ssh. Plink has the -pw command option for passwords. What I did was except ssh to ask me and write the password programmatically through the outputStream I obtained from my Process object. I looked for "password: ", and then wrote the password with a trailing newline.
Both plink and ssh will also ask if you trust the host if it is the first time you are connecting to it. So before just writing the password, check if the program wants verification from you: normally supplying "y" or "n". This should only have to happen the first time the client connects. It looks like thisPLINK:
The server's host key is not cached in the registry. You
have no guarantee that the server is the computer you
think it is.
The server's key fingerprint is:
1024 f8:43:61:4c:a2:5b:77:be:5b:a7:bb:1f:f7:79:b3:b7
If you trust this host, enter "y" to add the key to
PuTTY's cache and carry on connecting.
If you want to carry on connecting just once, without
adding the key to the cache, enter "n".
If you do not trust this host, press Return to abandon the
connection.
Store key in cache? (y/n)
SSH:
The authenticity of host '127.0.0.1 (127.0.0.1)' can't be established.
RSA key fingerprint is e1:02:13:c8:52:c2:23:41:9b:5b:58:2c:18:e6:59:af.
Are you sure you want to continue connecting (yes/no)?What I did was read character by character from the inputStream until I found things of interest ... like "password: ". You only need to search for this in your method which will launch the ssh or plink Process. Once you have verifyed yourself, you can just pass commands to the Process, which is an ssh connection.
My suggestion is to read() each byte from the Process's inputStream and write it to stdout. Look and see what you need to be looking for so you can interactive with the program correctly. You can't use readLine here becuase when the ssh asks for the password it does not print a newline. I do know for sure, that ssh will simply print, "passowrd: ". Plink will print this as well if the -pw option is not supplied.

Usually the way to make something else run on your computer outside your JVM is to use the Runtime.exec() method.

Call Bpel process through HTTP get or post method

I need to call BPEL process from Mobile.
In mobile we are using HTTP get or post methods. so can anybody tell me how to invoke BPEL(how to pass input to BPEL) by using HTTP get or post method.

I got the soluntion
we just need to change the binding in WSDL file from Soap to HTTP.
First of all add three namespaces in wsdl file
xmlns:mime="http://schemas.xmlsoap.org/wsdl/mime/"
xmlns:http="http://schemas.xmlsoap.org/wsdl/http/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
Then change the Request msg from element type to string type like below
<message name="UserLoggOffRequestMessage">
<part name="UserId" type="xsd:string"/> (add this one))
(remove this one)
</message>
Then change the binding
<binding name="UserLoggOffBinding" type="client:UserLoggOff">
<http:binding verb="GET"/>
<operation name="process">
<http:operation location="/process"/>
<http:urlEncoded/>
<output>
<mime:mimeString part="Body"/>
</output>
</operation>
</binding>
Then do some changes in service tag . we need to do the changes in location only.
we need to remove orabpel from location and add httpbinding
http://infva04718.vshodc.lntinfotech.com:8888/*orabpel*/MobileApplication/UserLoggOff/1.0
http://infva04718.vshodc.lntinfotech.com:8888/*httpbinding*/MobileApplication/UserLoggOff/1.0
do like following
<service name="UserLoggOff">
<port name="UserLoggOffPort" binding="client:UserLoggOffBinding">
<http:address location="http://infva04718.vshodc.lntinfotech.com:8888/httpbinding/MobileApplication/UserLoggOff/1.0"/>
</port>
</service>
Then deploy the process then u can invoke this
http://infva04718.vshodc.lntinfotech.com:8888/httpbinding/MobileApplication/UserLoggOff/process?UserId=a1
here process is name of process u want to invoke

Getting the final result of BPEL Process through Java

I am trying to invoke BPEL Process from Java code as follows:
NormalizedMessage res=deliveryService.request("BPELProcess1", "process", nm);
Map payload = res.getPayload();
System.out.println("size=="+payload.size());
Element e = (Element)payload.get("payload");
Node node = e.getFirstChild();
NodeList list = e.getChildNodes();
for(int k=0;k<list.getLength();k++){
Node n= list.item(k);
System.out.println("Node-->"+n.getNodeName());
The node names getting printed are :
Node-->#text
Node-->result
Node-->#text
When i retrieve value from these nodes using getNodeValue(), it is showing null for result. However through the BPEL Console, when i see the instance, it shows the result as 5 :
<outputVariable>
<part xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" name="payload">
<BPELProcess1ProcessResponse xmlns="http://xmlns.oracle.com/BPELProcess1">
<result>5</result>
</BPELProcess1ProcessResponse>
</part>
</outputVariable>
Any comments on this will help a lot. Thanks

this implies to be in the same initial context then the bpel engine, whicuh you cannot be as long as you are not either part of the ejb code of orabpel or a child of it. and if you are you can use the Locator API without the jndi properties.

end;Also tried the api itself - can execute mapping fine but problem with process flow says task not found/check type name and location
tried
works
DBMS_OUTPUT.PUT_LINE('Result: ' || TO_CHAR(owbsys.wb_rt_api_exec.run_task(

Any ideas?
