If you are passing data by using one of the Java™ EE
Connector Architecture (JCA) record interfaces that the WebSphere® optimized local adapters (WOLA) support, you can generate the Record classes by
using the Rational® Application Developer CICS®/IMS
Java Data Binding wizard.
About this task
You can use the Rational Application Developer
CICS/IMS Java Data Binding wizard to generate a
javax.resource.cci.Record object that can replace the byte array that sends and receives data in the
IndexRecordImpl and MappedRecordImpl objects. To use the generated Record classes, you must set up
an extra library in the Liberty server
instance to enable the server instance to serialize and deserialize the data in the Record
object.
Procedure
- Copy the marshalling JAR file from Rational
Application Developer into a lib subdirectory underneath the server
configuration directory, which contains the server.xml file.
The
licensed, redistributable marshall.jar file is located in the
com.ibm.ccl.commonj.connector.metadata_version.timestamp plug-in
in the runtime folder. The exact name of the plug-in folder varies depending on
the Rational Application Developer version.
- In the server.xml file, create a
library element
that points to the new location of the marshalling JAR file, as shown in the following
example. Replace
marshall.jar with the actual name
of your marshalling JAR
file.
<!-- Library required by RAD generated application classes. -->
<library id="MarshallLib">
<file name="${server.config.dir}/lib/marshall.jar"/>
</library>
- In the server.xml file, add the new library to the application
definition that contains the generated Record class by specifying the library ID that you created on
a
classloader element. The following example adds the MarshallLib
library to the WolaApp
application.
<!-- Application installed in ${server.config.dir}/apps. -->
<application id="WolaApp" name="WolaApp" location="OLA.ear">
<classloader commonLibraryRef="MarshallLib"/>
</application>
