Oracle BPM Solution ArchitectureHow should we develop BPM Processes???

One Application

One Project One Process

One Project

SeveralApplications

OR

Each process isdeployed isolated

All processes aredeployed together

Several Process

JDeveloperperformance issues

Easier to structure byBusiness Area

Oracle BPM Solution ArchitectureHow should we initiate BPM Processes???One Main Process for all Processes Middle Solution

Business Area X

One Main Process Per Business Area

Business Area X

Business Area Y

Harder to maintain inputparameters for all processes

More dynamic solution More flexible… but…

• Multi device application

• Responsive user interfaces

• Faster development cycle

• Integrated with- Oracle BPM- Oracle SOA- Oracle Webcenter Content

Why Link BPM Framework??


• Real Time Indicators

• Quick Instant Actions

• Easy Data Access

Lessons Learned

Use Case

Exception occurred when binding was invoked. Exception occurred during invocation of JCA binding:

"JCA Binding execute of Reference operation ‘setDBData' failed due to: Interaction processing error. Error while processing the execution of the SCHEMA.DATABASE_OPERATION API. Cause: java.lang.NullPointerException

Check to ensure that the XML containing parameter data matches the parameter definitions in the XSD. This exception is considered retriable, likely due to a modelling mistake. The invoked JCA adapter raised a resource exception. Please examine the above error message carefully to determine a resolution.

Lesson #2Use Case

oracle.jdeveloper.webservices.model.WebServiceException:

[ERROR] only one globalBindings customizations is allowed in a whole compilation line 7 of wsdlhttp://127.0.0.1:7101/integration/services/TaskService/TaskServicePort?XSD=TaskCommand.xsd

Lesson #2Solution

JDeveloper 11.1.2.3

JDeveloper 11.1.2.4

Was not a option for project

Lesson #3Use Case

parsing WSDL…

[ERROR] “wsdlhttp://127.0.0.1:7101/soa-infra/services/default/myProcess/myXSD.xsd” is not part if this compilation. Is this a mistake for “wsdlhttp://127.0.0.1:7101/soa-infra/services/default/myProcess.Service?WSDL#types?schema1”?

Line 2 of “wsdlfile:/c:/Users/M730B~1.ELB/AppData/Local/Temp/JDev.JaxBinding.5510295535565202477.xml”

JDeveloper11.1.2.3

Lesson #3Workarround

1. Copy WSDL to your File System

2. Run the wizard

3. Select WSDL from file system

4. Specify• Override Default Root Package• Override Default Types Root Package

JDeveloper 12.2.1 works fine
