How can I invoke BPEL process to run ?

Hi,
after deploying the bpel process, which way I can invoke it without BPEl console ?
Can I invoke it from inside of my stored procedure
or creating (and invoking then) concurrent-process in OEBS ?

Clemen,
Thanks for the response.
Assuming that I created right xml(+ namespaces) in the stored procedure, put it into varchar2 parameter, and invoked BPEL WS. My question is how I can parse it?
Advise please. I'm a rookie on the XML.
I also tried to pass delimited string from plsql and then parse it using orcl:create-nodeset-from-delimited-string. Unfortunately I didn't figure out what I have to put as a QName parameter of that function. The documentation is insufficient. There is no any sample with that function. Another guy is also was struggling with it: create-nodeset-from-delimited-string
Maybe you can clarify it?
Thank you in advance.
Sergey.

How can I watch the process is running in program?

In my program, I fork some processes, and I must watch them timing, how can I know that these processes is running?

<pre>
There could be many way for to see what process is doing.
Easiest is to use "truss" on the process or the program.
Please see the man page of truss.
You can do :
truss -f -p pid_of_process
or
truss -f -o /tmp/out -p pid_of_process &
tail -f /tmp/out
or
truss -f program_exe
Otherwise you can use dbx, run the process in dbx and set
breakpoints at various levels.
Thanks

How can I find how many instances of BPEL process is in running state ? Any code/API ? help ? Thanks

Check the class com.oracle.bpel.client.Locator...

How can one invoke a WebLogic EJB from a BPEL Server hosted on OC4J?

How can one invoke a WebLogic EJB from a BPEL Server hosted on OC4J?
Reason I ask is I keep getting this error:
javax.naming.NoInitialContextException: Cannot instantiate cla
ss: weblogic.jndi.WLInitialContextFactory [Root exception is java.lang.ClassNotF
oundException: weblogic.jndi.WLInitialContextFactory]
Note: I am using <bpelx:exec> as a way to execute some java program.
Essentially my java client (essentially an EJB client hosted on Oc4J) needs access to wlclient.jar since it needs access to weblogic.jndi.WLInitialContextFactory. I have a EJB client running on BPEL server hosted on Oc4J that needs to access some EJBs hosted on weblogic.
Where do I place this wlclient.jar so that BPEL PM can start peacefully and at runtime discover the InitialContextFactory classes?
Placing it in the j2ee/home/applib doesn't solve the problem. The server fails to start up if I do this
I tried placing it in BPEL-INF\lib directory ...
I still get the same exception...see below for exception dump
I verified the BPEL suitcase, and it in fact does contain the jar file wlclient.jar
integration\orabpel\domains\default\deploy contains the bpel_BPELProcess2_1.0.jar file and snapshot of that is as follows:
<PRE>
│ bpel.xml
│ BPELProcess2.bpel
│ BPELProcess2.jpr
│ BPELProcess2.wsdl
│ bpel_BPELProcess2_1.0.jar
│ build.xml
│ buildxml.copy
│ graphics.xml
│
├───BPEL-INF
│ └───lib
│ myEJB.jar
│ wlclient.jar
│
├───META-INF
│ MANIFEST.MF
│
└───output
bpel_BPELProcess2_1.0.jar
</PRE>
I tried using the BPEL-INF\jar directory...Is this something the obant automatically detects? or do I have to modify the build.xml? I created this directory and let Jdev deploy to local BPEL server->default domain handle it
#####################3
I even tried copying the wlclient.jar to
integration\orabpel\system\classes but this doesn't help since the BPEL PM fails to start if I explode this jar into this directory.
In short,where do I place the wlclient.jar so that this exception can be contained.
I edited the build.xml to point to the jar, that too didn't work, unless I made some mistake in the file
<bpelc classpath="${basedir}/BPEL-INF/classes;${home}/system/classes;${home}/lib/j2ee_1.3.01.jar;${basedir}/BPEL-INF/jar/wlclient.jar" input="${basedir}/bpel.xml" rev="${rev}" deploy="${deploy}" />
</target>

with the bpelx all I have is two lines of code that creates a java object and calls a method on it.
The method does this:
    private String initialContextFactory = "weblogic.jndi.WLInitialContextFactory";
    private String providerUrl = "t3://localhost:7001";
    private String urlPkgPrefixes = "";
    private String mapEjbJndiName = "ejb/mycompany/Redlands";
    public String getDefaultMapName() {
      try {
          Hashtable env = new Hashtable();
          env.put(Context.INITIAL_CONTEXT_FACTORY, getInitialContextFactory());
          env.put(Context.PROVIDER_URL, getProviderUrl());
          if (getUrlPkgPrefixes() != null && !getUrlPkgPrefixes().equals(""))
              env.put(Context.URL_PKG_PREFIXES, getUrlPkgPrefixes());
          System.out.println("    " + getInitialContextFactory());
          System.out.println("    " + getProviderUrl());
          System.out.println("    " + getUrlPkgPrefixes());
          System.out.println("    " + getEjbName());
          // Get a naming context
          context = new InitialContext(env);
           Object ms = context.lookup(getEjbName());
          MyEJBHome home = (MyEJBHome ) PortableRemoteObject.narrow(ms, MyEJBHome.class);
          myEjb = home.create();
          return myEjb.getDefaultName();
      } catch (RemoteException re){
          System.out.println(re.getCause().getMessage());
      catch (Exception ex) {
          ex.printStackTrace();
      return null; //if unable to resolve the context factory etc...
    }

I did exactly as you suggested. I edited the application.xml and added this
<library path="C:\ArcGIS\test\bea\wlclient.jar"/>
I didn't add weblogic because the needed classes were all in wlclient.jar
I also edited the BASE_OB_CLASSPATH to include this jar.
Here is the result when I just start BPEL PM Server. Somehow BPEL PM doesn't like to have wlclient.jar in its classpath during startup.

Invoking BPEL process: how to decide it's two way or one way operation

Hi,
I'm using IDeliveryService to invoke BPEL process. Is there API available that allows me to check whether the operation is two way so I call IDeliveryService.request() or is one way so I call IDeliveryService.post()?
Thanks,
Qian

hi,
By observing WSDL of the BPEL process you can identify that whether its
two way operation or one way. If operation has two variables - both input & output
then its way operation and if the opration has only one variable - input variable then
its one way operation.
OR are you asking how to check it at runtime without looking at the WSDL...?

don't see any invoke in your client against the intiate operation.. - which creates the correlation
only 2 of them
<invoke name="Invoke_1" partnerLink="PartnerLink_1" portType="ns1:CorrelatedBPELProcess" operation="receive1" inputVariable="Invoke_1_receive1_InputVariable"/>
<invoke name="Invoke_2" partnerLink="PartnerLink_1" portType="ns1:CorrelatedBPELProcess" operation="receive2" inputVariable="Invoke_2_receive2_InputVariable"/>
compared to this def of the process
<portType name="CorrelatedBPELProcess">
<operation name="initiate">
<input message="client:CorrelatedBPELProcessRequestMessage"/>
</operation>
<operation name="receive1">
<input message="client:CorrelatedBPELProcessRequestMessage"/>
</operation>
<operation name="receive2">
<input message="client:CorrelatedBPELProcessRequestMessage"/>
</operation>

How to invoke BPEL process from database?

Who can get an advice: what technology is better to use for invoking BPEL process, that is deployed to remote server, from database? What LIBs should I load into this database?
History: after successful trying Oracle RMI-example whith JDeveloper, I repeated the same had loaded my .jar and all listed in project Oracle .jar's into the database and received error "..class not resolved..".
Thank you.

How to know BPEL process is running

Hi,
I have BPEL process which is triggerred by FileAdapter. File Adapter polls for every 120seconds and if any file exists, it reads and BPEL process is initiated.
As BPEL proccess is big and sometimes it executes more than 120seconds and it depends on environment with less load process faster and more load its takes more time.
Due to this is there a way to know BPEL process is running before fetching new file or before starting actual BPEL process.
JDev: 11.1.1.6.0
Thanks,
Bhaskar

Can a singleton bpel will resolve your problem ?
At a time only one bpel process will be running there wont be any parallel instances for that bpel. In that way there wont be any second instance created until the first instance has done with its job.

hey mgrovr..
how to ensure that my jsps are under orabpel. i m getting a javax.naming.NameNotFoundException: ejb/collaxa/system/DomainManagerBean not found exception wile invoking bpel process from jsp. I have created the jsps in Jdeveloper and i'm running it from there only.
Can u tell me a way to keep me application under orabpel

Invoking BPEL process on startup

Hi there,
Does anyone have suggestions as to how i can run a BPEL process automatically when BPEL PM starts up? I would prefer not to use external tools. I tried using the OC4J startup classes invoking it via java, but the BPEL engine has not started the processes yet.
I'm using 10.1.3.3.0
Thanks

Hi,
Your current usecase:
Step 1.java app polls db-->jms topic1 written to that jmsbroker/consumers consume
Step 2.jms broker receives msgs from topic1-->invokes http post
Question: It is unclear whether you will have other consumers to this jms msg or not and hence two options.
Here are the ways to use BPEL with this:
Option 1:
If you dont want the current JMS broker but want a JMS provider so other consumers can consume the msg
1.java app polls db, gets xml msg, puts msgs into Oracle JMS.
2. Within a bpel process, the jms adapter listens for arrival of msgs on a q/topic and calls http post (inline java exec or http binding)
For bpel process doing http post refer: for inline java call<bpelhome>/samples/references/javaexec) and "702Bindings" for http binding.
Application specific JMS headers will be set by the enqueuing client (your java app in this case). In general getting and setting of JMS headers is possible within bpel.
Option 2:
If you dont want the current JMS broker and dont care about other msg consumers either
1. java app polls db, gets xml msg, invokes bpel process thro bpel java api
Ref: 102.InvokingProcesses
2. Within the bpel process, the steps are : a) receive msg frm client b) do http post
Again, if you directly have access to the underlying tables, refer to Option 1 in the previous post.
Wrt "Also, is there a way that I can make my existing java application to be initialized by a bpel process",
yes within bpel you can write inline java or do wsif binding to invoke java code.

Invoke BPEL process with the webservice interface

I'm using Oracle BPEL PM 10.1.2.x.
Follow the example comes with the BPEL PM, i can invoke the BPEL process in a J2EE project (with the webservice interface). The example named "UseStockReviewSheet".
Then i tried to invoke the BPEL process i designed with Eclipse BPEL Designer. The version of BPEL designer for Eclipse is 0.9.13.
I failed and got following errors:

I can invoke my BPEL process in BPEL console, not in J2EE project. bpws:getVariableData('input','payload','/tns:CreditFlowRequest/tns:input')" is null.
The error message contains some Chineses word. I'm new to BPEL, hope someone can give me a hint on how to solve this problem.
Thanks a billion!

Problem invoking BPEL process via SOAP

Hi,
I have a BPEL process which runs perfectly when invoked from the BPEL console. Now I try to invoke the BPEL process from another (Java) program and get some strange error message in the client. After enabling debug logging I can see a NullPointerException in the BPEL server log (it's Oracle BPEL server 2.1.2 build 1226).
Here the output from the console:

Any suggestion?
Thanks in advance...

This sounds very similar to how my BPEL process behaves. I'm unable to post XML input into the "XML Source" region of the initiate screen unless the input is properly wrapped in the respective message type element.
Make sure your invoking client code is wrapping the input properly with the message type XML elements.

Invoking bpel process from java in oracle soa/bpm 11g

Hi,
We have some java code to invoke bpel process in oracle BPM 10g following the instructions in http://download-east.oracle.com/docs/cd/B14099_19/integrate.1012/b14448/invoke.htm.
Basically the steps are:
1) get a Locator (com.oracle.bpel.client.Locator)
2) get IDeliveryService (com.oracle.bpel.client.delivery.IDeliveryService) reference from locator
3) call IDeliveryService method request or post with input message and get the response back.
Recently we want to migrated from oracle bpm 10g to oracle soa/bpm 11g. But I can not find the similar API in 11g. It seems now some adapter/binding need to be added in exposed service lane in soa composite view, for example, ADF-BC, direct binding etc, in order to allow java to invoke a bpel process. Here are two very useful links from Edwin about the detail how this is implemented.
http://biemond.blogspot.com/2009/11/invoking-soa-suite-11g-service-from.html
http://biemond.blogspot.com/2009/11/calling-soa-suite-direct-binding.html?showComment=1285198033913#comment-c1055322845511794252
My question is:
1) what are the choices and the official/best way to invoke a bpel process in oracle soa/bpm 11g from java?
2) does user need to add an adapter/binding in exposed service lane in order to let the bpel service be called in java?
3) what is the real difference between a bpm application and soa application in 11g?
I will really appreciate any expert's opinion.
Thanks,
Bin

Thanks for your reply and confirmation, really appreciate it.
Yes, I found the difference of the invoking process API and was able to invoke bpel process using direct and ADF-BC binding by following Edwin's blog. But I have not found any official reference to compare this API difference between 10g and 11g ( I will mark this question as answered if anyone can find an official source from oracle, need to prove it to the team). The API to work with human task workflow seems pretty much the same between 10g and 11g.

How can I invoke BPEL process to run ?
