Invoke Java code within BPM process

Hi,
I have a use case where I need to retrieve a property from database and set the value to a process variable. Is there a way I can achieve this?
Also, is there a way to invoke a piece of java code from the automatic activity within a BPM process?
Thanks,
Suren.

The best way to do this is to use the spring component. You will need your java code setup as a spring bean in the spring context file and then it can be exposed to the BPM process as an sca service.

Help with use of Java Stored Procedures to invoke Java Code within Applicat

Good afternoon everyone
Our development team is looking for some assistance/validation of a design strategy we are deploying for a client. Let me first layout the environment and then the design issue at hand:
Business User Workstation component: Oracle SQL*Developer 1.5.x
Reporting Tool: Actuate e.Spreadsheet A10
Application Web UI: J2EE application developed with Eclipse
Application Scripting: Application has a scripting component whereby business users can write Oracle PL/SQL to perform many of the functions that are available in the Web UI, but can be batched up or repeated several times.
Application Server WebLogic 9.2.3 (client constraint)
Database Serve: Oracle 11g, Release 11.1.0.7
Lots of other stuff included but irrelevant for this conversation.
Here's the scenario in question:
1.     Through the scripting solution, the application user must use PL/SQL to invoke functionality within the Web UI. All PL/SQL that the application user creates does not contain any SQL. Instead our security model mandates that “pre-defined” routines will perform all of the SQL operations against the database; the application user simply invokes the stored procedures of functions to perform activities in the database.
2.     There is a component of the scripting application that facilitates the creation of reports. In our application, we are using Actuate’s e.Spreadsheet Engine to create the report and format the report based on a template. The template is provided as input, as well as other data items, into Actuate for processing. The net result is the report is created by the Actuate e.Spreadsheet engine in pdf format and then sent back to the user for distribution to other users in the company.
3.     The Actuate e.Spreadsheet engine consists of one or more JAR files within the Application Server framework. The Web UI utilizes these JAR files as well to perform report generation and data manipulation activities. In the case of the reporting functionality, the pdf report that is generated by Actuate is returned into either the Web UI or into the scripting component for persistence in the database. The mechanism exists to create multi-step jobs that can create multiple reports in one run.
4.     So to facilitate the above, we are creating one or more Java Stored Procedures that will mediate the communication between the PL/SQL the user’s create and the Java components that are required for business processing. PL/SQL will invoke one or more Java Stored Procedures. Then the Java Stored Procedures invoke Actuate e.Spreadsheet, generate the report, saves the report in the database and returns control back to the invoking procedure.
So the question is: Is this a viable and correct use of Oracle Java Stored Procedures. What are the advantages/disadvantages of doing so? Any security issues or potholes that you can think of? Tuning issues for the JVMs? Any white papers that you can think of?
For any Oracle employees that respond, material such as Oracle Whitepapers, etc. would be great.
I can be contacted at (313) 227-4350 or at [email protected]
Thanks in advance.

So are you planning on loading the entire e.Spreadsheet engine into the database server's JVM?
If so, I would expect that to work, but I expect that you'd have some performance issues. I'd expect that the process of building these PDFs is going to be relatively expensive. Tuning the database server's JVM tends to be rather more challenging than tuning JVM's in an app server.
If not, I'm not sure how the Java stored procedure would invoke the e.Spreadsheet engine on the application server. It is possible to use Oracle AQ to send a JMS message, but I don't think you can use the standard J2EE JMS APIs-- I think you'd have to use Oracle's AQ interface.

Use of Java Code within the generated XML Forms Stylesheets

Hello,
is the use of Java-Code possible with the XSL-Files generated by XML-Forms, as possible in standard XSLs? I know that this would mean a modification.
kind regards,
Marco

Hi Marco,
I "executed" some java code within XSLs file. I have quoted the word executed because I didn't really run java code, but I used a simply trick that I describe you below.
Into your XSLs put an iframe which is hided (it has an height of 0 pixel). As src of the iframe put the address of a portal component which execute your code (in my case calculate some PCD URL of some pages into a defined role). As result of component execution, I use the response.write method in order to execute some jscript code, which is able to interact with the HTML generated by XSLs files, for example in my case response.write put the PCD URL into a drop down list placed into the "edit" form.
This works fine. I don't know if is suitable also for your case, anyway could be a hint, but pay attention to Roland's recommendations.
Ciao

NoSuchMethodError when invoking EJB Component From BPM Process

I created BPM process which contains global creation activity and user interactive activity and catalogued ejb component. In user interactive activity i wrote the Process Business Language to invoke Remote EJB deployed in weblogic server. When i tried to execute user interactive activity, i got the following exception.

what i noticed here is in Oracle BPM Studio there is weblogic jar file which contains Kernel status file. The KernelStatus file do not have "isThinIIOPClient method". But in wlclient jar file there is Kernel status class which contains "isThinIIOPClient" method.
How can I override the weblogic.jar and wlclient.jar for Oracle BPM?
Please help me to resolve this problem.

How to execute a custom java code from the process

Hi All,
I'm writing a process to generate the PDF and it works fine. Now, at the end or in the middle of the process, i would like to execute/write a java code then it will be invoked when the process running. Assume not using web service, is there another way? samples how to write custom code?
Thanks,

The Execute Script service allows you to execute java code on a particular step.
A more robust solution would be to create a custom component for your custom code.

How to access/invoke Web Service from BPM Process

The following steps required to attach and invoke web service method from process:
1) Add a module in the catalog for ex WebServiceMO
2) Add WebService Catalog component demoWebService in WebServiceMO
3) Put ur WSDL address in WSDL address field like "http://localhost:8080/test/test?wsdl"
4) Click next to introspect the web service it will import required files and setting from the url to your project
5) Now for invoking webservice just call the method for ex.
@return as String[]
getTestStringList(TestInterfaceService, out @return : @return)
logMessage "web service calll result >>"+length(@return)+">>>"+@return[0]
Here @ return is the return from webservice call.
this way u can access web service from BPM process.
Edited by: Anurag Yadav on Jul 17, 2009 2:19 PM

I have a web service which does not return any value but when I introspect the web service, I have an out parameter to it.. Not sure why?
For e.g.
TestServiceListener.addTestNotes(TestNotes : testNotes, out TestNoteResponse : testNoteResponse);
So here I see an out parameter, but my web-service has no out parameter...
Any idea why is this happening?

Call Java Method from BPM Process

Hi,
I have defined a java class with set of methods , and I want to know if there is any way to call those methods from a BPM process..
Thanks in Advance,,
Best Regards,,
Ola Essa..

Use the spring component context in soa suite instead of ejb. Look for documentation in soa suite developer guide. Only if you have existing ejbs then use ejb adapters.

Dynamic navigation from inside the java code within the project

I want to create dynamic navigation in my project.
On my first page I need to get to a second servlet page by the use of dynamic coding. In normal servlets I would use response.redirect() but I cant here in the creator world and I am stuck on this point.
Any ideas or directions on how to proceed?
I know how to use the navigation XML file and know how to modify the file in question.

Well I sort of worked out what had to be done, and the references that everyone gave me was amazing and I am thankful...

Calling simple Java Code from 11g BPM

Hi,
I know this has been round the houses but I cant find a satisfactory solution for my scenario. I would like to call some simple java code from BPM (11.1.1.6). I guess I need to expose it as a service but it seems overkill to be via soap so any advice you can give would be much appreciated. Creating a jar that I can call somehow would be perfect.
This is my scenario:
- I am creating a Security POC for BPM
- The BPM Process is exposed as a web service and authenticated using SAML
- I am testing by calling the WS from OSB
- I want to be able to get the WLS Principal and display the username and the roles for the launching user, from within the BPM process
- This is possible using some simple weblogic client api code shown below
- So all I want to do is call this code from BPM somehow
- Anyone point me in the right direction ?
cheers
Tony
subject = Security.getCurrentSubject();
for(Principal p: subject.getPrincipals()) {
if(p instanceof WLSGroupImpl) {
groupList.add(p.getName());
} else if (p instanceof WLSUser) {
principal = p.getName();
}

Should I do this with Java Code or Stored Procs ? (for best performance)

Hi All,
I need to decide where should I implement my business logic, in Java code or Stored procs.
Here is the requirement :
- One Order has 70 products (Order_Table )
- Can be duplicate products, so I have to do summarize / grouping by product
- For every product, I have to check, if it is entitled for a Bonus product, then I have to Insert one to Bonus_Table.
- This is done when/after the transaction is SAVED (COMMIT)
The question is, which one has better PERFORMANCE :
(1) Create a rowsetIterator on the Order details (70 products) and call a stored procedure to do the logic for every single product (so that the Insert to Bonus_Table done in stored proc). means the stored proc will be called 70 times.
OR
(2) After the transaction is COMMITted, call the stored procs ONCE to do the logic for all the products at once.
OR
(3) I do all the logic with Java Code within ADF
Given the requirement above, which approach is most efficient / best performance ?
Thank you very much,
xtanto

Problem with this is that you ask 100 people and you probably get 100 different answers. ;o)
Many would say that you push as much business logic into the database with your data; others might say you only put data in your database and your business logic is kept on the application server.
In reality your would probably have a mix of both and your decision would probably be influenced by your own background ...
Can't be more precise than that.

Hi Marco,
I "executed" some java code within XSLs file. I have quoted the word executed because I didn't really run java code, but I used a simply trick that I describe you below.
Into your XSLs put an iframe which is hided (it has an height of 0 pixel). As src of the iframe put the address of a portal component which execute your code (in my case calculate some PCD URL of some pages into a defined role). As result of component execution, I use the response.write method in order to execute some jscript code, which is able to interact with the HTML generated by XSLs files, for example in my case response.write put the PCD URL into a drop down list placed into the "edit" form.
This works fine. I don't know if is suitable also for your case, anyway could be a hint, but pay attention to Roland's recommendations.
Ciao
Roberto

Class Not found Exception for invoking BPEL process through the Java code

Hi.
The JDeveloper IDE raise the Exception From the invoking the BPEL process through the java code .Class Not Found Exception (Locator,ID.......).What is process of importing these classes from API.

In your code (.bpel file) import the library using the bpelx:exec tag. For example the adding the following entry in your .bpel file imports the com.oracle.bpel.client.util library.
<bpelx:exec import="com.oracle.bpel.client.util.*"/>

How : Invoke asynchronous BPM process with callback within loop?

Hi All,
I'm currently using the 11g suite to create 2 BPM processes (Validate and Review). Process Validate is asynchronous and has a callback facility. I intend to invoke Validate from Review as a subprocess. My question would be, is it possible to invoke an asynchronous process with a call back? Can this be done in a loop?
JDev : 111.1.1.4
Thanks,
PP.

Sai,
Which IDE are you using to build the client? (In fact it doesn't matter)
Just put the jar files path into the classpath as John told. In order to find which jar files you need in this process, you can use eclipse java - jar class finder (which works with NWDS as well). Give it the class name(in this case commons.bla.bla...) and your jar files' folder, it will show you which jar file you need to put into the classpath.
Just a little googling may help you with the class finder

String xml = "<ns1:HelloWorldProcessRequest><ns1:input>India</ns1:input></ns1:HelloWorldProcessRequest>" ;
Locator locator = new Locator("default","bpel");
IDeliveryService deliveryService = (IDeliveryService)locator.lookupService(IDeliveryService.SERVICE_NAME );
NormalizedMessage nm = new NormalizedMessage( );
nm.addPart("payload", xml);
NormalizedMessage res = deliveryService.request("HelloWorld", "process", nm);
Map payload = res.getPayload();
System.out.println("HelloWorld Service Response is:"+payload.get("payload"));
Could you figure out ,what might I missing over here..........
Please help me out !

Very-very thanks raphel,but still facing problem
I did following changes in my code
String xml = "<ns1:HelloWorldProcessRequest><ns1:input>India</ns1:input></ns1:HelloWorldProcessRequest>";
Properties props=new Properties();
props.setProperty("orabpel.platform","ias_10g");
props.setProperty("java.naming.factory.initial","com.evermind.server.rmi.RMIInitialContextFactory");
props.setProperty("java.naming.provider.url","opmn:ormi://localhost:9700/home/orabpel");
props.setProperty("java.naming.security.principal","oc4jadmin");
props.setProperty("java.naming.security.credentials","welcome1");
props.setProperty("dedicated.rmicontext", "true");
Locator locator = new Locator("default","bpel",props);
IDeliveryService deliveryService = (IDeliveryService)locator.lookupService(IDeliveryService.SERVICE_NAME );
NormalizedMessage nm = new NormalizedMessage( );
nm.addPart("payload", xml);
NormalizedMessage res = deliveryService.request("HelloWorld", "initiate", nm);
// deliveryService.post("HelloWorld", "initiate", nm);
Map payload = res.getPayload();
System.out.println("HelloWorld Service Response is:"+payload.get("payload"));
and response is herewith :
