PM73446: USING A THIRD-PARTY SCA RUNTIME WITHIN A WEB APPLICATION MAY FAIL TO INSTALL DUE TO CONFLICTS WITH THE WEBSPHERE NATIVE SCA

8.5.0.2: WebSphere Application Server V8.5 Fix Pack 2

APAR status

• Closed as program error.

Error description

• Web Applications which embed a third-party Service Component
  Architecture (SCA) Runtime, for example the Apache Tuscany SCA
  runtime, may fail to install when the WebSphere Application
  Server native SCA support attempts to validate that the SCA
  artifacts within the Web Application comply with the WebSphere
  Application Server SCA requirements which may be different
  from the requirements of the third-party runtime.
  
  Examples of error message that may be produced in this
  situation are:
  
  CWSAM0114E: SCA Binding was not found configured on service
  {0}. Only SCA Binding is supported for services in WAR
  composites.
  
  CWSAM0113W: Multiple bindings were found in service {0}. Only
  SCA Binding is supported for services in WAR composites
  
  CWSAM0108E: The {0} step ended with an exception. The
  Application Serverfound the META-INF/sca-contribution.xml file
  within the Web archive (WAR) file, which is not supported.
  
  CWSAM0109E: The {0} step ended with an exception. The
  Application Server found multiple composites in the
  META-INF/sca-deployables directory under the Web archive (WAR)
  file. For the Service Component Architecture (SCA) WAR file,
  the product supports only a single composite in the
  META-INF/sca-deployables directory
  

Local fix

• add a new system property that disables WebSphere's inbuilt
  SCA WebApp support. That will be global to the server though so
  they wont be able to run a mix of Tuscany and WebSphere SCA
  WebApps. If that is acceptable then the system property seems
  the best approach.

Problem conclusion

• A new system property has been added to disable WebSphere
  Application Server native SCA support in Java EE Applications.
  Setting the system property
  'com.ibm.ws.soa.sca.admin.osoa.scawar' with a value of
  'disabled' will cause Application Server native SCA support to
  ignore the SCA artifacts within the application.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.5.0.2.  Please refer to the Recommended Updates
