Establishing custom adapters for federated repositories
Out of the box adapters for federated repositories provide File, LDAP, and Database adapter for your use. These adapters implement the com.ibm.wsspi.wim.Repository software programming interface (SPI). Custom adapters for federated repositories need to implement the same SPI.
Refer to the Repository SPI implementation information in the related references for information about the custom adapters for federated repositories SPI.
Refer to the sample custom adapter code that is available in the vmmsampleadapter.jar file. The JAR file contains the sample customer adapter code in the src/ directory. The vmmsampleadapter.jar can be downloaded at this location: http://www.ibm.com/developerworks/websphere/library/samples/vmmsampleadapter.html
- The sample provided is intended to familiarize you with the features of custom adapters for federated repositories and the handling of various types of dataobjects. Do not use this sample in an actual production environment.
- Copy the AbstractAdapterImpl class and rename it before making changes. Make sure that the new name is appropriate for your adapter.
Custom adapters for federated repositories must not depend on any WAS components, such as data sources and enterprise beans. These WAS components require that security is initialized and enabled prior to startup. If your implementation of the virtual member manager custom adapter needs to use data sources to connect to a database, use Java database connectivity (JDBC) to make the connection during server startup. Then, at a later time, switch to using the data sources when the data source is available.
Procedure
- Build your implementation.
EMF JAR files contain version number in their names, such as v200607270021. Make sure to change the version number to reflect your installation. To compile your code, you need the following JAR files in the classpath:
- WAS_HOME/plugins/com.ibm.ws.runtime_6.1.0.jar
- WAS_HOME/plugins/org.eclipse.emf.commonj.sdo_2.1.0.v200607270021.jar
- WAS_HOME/plugins/org.eclipse.emf.ecore_2.2.1.v200607270021.jar
- WAS_HOME/plugins/org.eclipse.emf.common_2.2.1.v200607270021.jar
- WAS_HOME/plugins/org.eclipse.emf.ecore.xmi_2.2.0.v200607270021.jar
- WAS_HOME/plugins/org.eclipse.emf.ecore.sdo_2.2.0.v200607270021.jar
Here is an example:
WAS_HOME/java/bin/javac -classpath WAS_HOME/plugins/com.ibm.ws.runtime_6.1.0.jar; WAS_HOME/plugins/org.eclipse.emf.commonj.sdo_2.1.0. v200607270021.jar; WAS_HOME /plugins/org.eclipse.emf.ecore_2.2.1.v200607270021.jar; WAS_HOME/plugins/org.eclipse.emf.common_2.2.1. v200607270021.jar; WAS_HOME/plugins/org. eclipse.emf.ecore.xmi_2.2.0.v200607270021.jar; WAS_HOME/plugins/org.eclipse.emf.ecore.sdo_2.2.0.v200607270021.jar your_implementation_file.java- Copy the generated class files or the packaged JAR file to the product classpath. The preferred location is the WAS_HOME/lib/ext directory. This should be copied to the classpaths of all the product processes (cell and all NodeAgents).
- Configure your custom adapter by following the steps in Configure custom adapters for federated repositories using wsadmin.
- Test your custom adapter by following the steps in Use custom adapters for federated repositories
