Oracle® SOA 12c 12.2.1 Quick Start

Starting in 12(12.1.3), we can no longer download SOA extensions. We need to use a Quick Start distribution to obtain a version of JDeveloper pre-configured for either SOA Suite or Business Process Management Suite. This thread discusses the installation of Oracle SOA Suite Quick Start.


  • Navigate to URL to download the zip files for SOA Suite Quick Start. Download both the files. 
http://www.oracle.com/technetwork/middleware/soasuite/downloads/index.html

  • Extract the contents of both the files
  • Ensure that contents of both the zip files are in the same folder



  • JDK 1.8 is a minimum requirement for running the software. Please download and install JDK 1.8 or above. Set the JAVA_HOME environment variable.


  • Navigate to the unzipped folder for Disk 1 of 1 and give the command
java -jar fmw_12.2.1.0.0_soa_quickstart.jar


  • This will launch the SOA installer

Oracle® Fusion Middleware Weblogic 10.3.6: JPA client error

In a recent IoT project, MindTelligent team ran into an issue with connecting the JPA (Session Facade Client) with Session Beans when deployed on Weblogic 10.3.6 JDK 1.7 and client running on JDeveloper 11.1.1.7.

Following exception is thrown

java.io.InvalidClassException: org.eclipse.persistence.exceptions.ValidationException; local class incompatible: stream classdesc serialVersionUID = 8323218586942907354, local class serialVersionUID = 7573113798854854020

Issue:
The version of the Class org.eclipse.persistence.exceptions.ValidationException is different in JDeveloper and Weblogic instance on which the EJB 3.0 are running.

Solution:

FTP the  org.eclipse.persistence_1.2.0.0_2-3.jar from the Weblogic Instance where the deployed beans are running and include it in the CLASSPATH of the client as shown below. This should resolve the issue
