• 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 #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
