Configure a shared library using scripting

 

You can use scripting to configure a shared library for appservers. Before starting this task, the wsadmin tool must be running. See the Start the wsadmin scripting client article for more information.

 

Overview

Perform the following steps to configure an appserver to use a shared library.

 

Procedure

1. Identify the server and assign it to the server variable. For example:

   Use Jacl:

   set serv [$AdminConfig getid /Cell:mycell/Node:mynode/Server:server1/]
   

   • Use Jython:

     serv = AdminConfig.getid('/Cell:mycell/Node:mynode/Server:server1/') print serv
     

   where:

   set	Jacl command
   serv	variable name
   $	Jacl operator for substituting a variable name with its value
   AdminConfig	object that represents the WebSphere Application Server configuration
   getid	AdminConfig command
   Cell	attribute
   mycell	value of the attribute
   Node	attribute
   mynode	value of the attribute
   Server	attribute
   server1	value of the attribute

   Example output:

   server1(cells/mycell/nodes/mynode/servers/server1|server.xml#Server_1)
   

2. Create the shared library in the server. For example:

   Use Jacl:

   $AdminConfig create Library $serv {{name mySharedLibrary} {classPath c:/mySharedLibraryClasspath}}
   

   Use Jython:

   print AdminConfig.create('Library', serv, [['name', 'mySharedLibrary'], ['classPath',  
   'c:/mySharedLibraryClasspath']])
   
   

   where:

   $	Jacl operator for substituting a variable name with its value
   AdminConfig	object that represents the WebSphere Application Server configuration
   create	AdminConfig command
   Library	attribute
   serv	evaluates the ID of the server that is specified in step number 1
   name	attribute
   mySharedLibrary	value of the name attribute
   classPath	attribute
   /mySharedLibraryClasspath	value of the classpath attribute
   print	Jython command

   Example output:

   MysharedLibrary(cells/mycell/nodes/mynode/servers/server1|libraries.xml#Library_1)
   

3. Identify the appserver from the server and assign it to the appServer variable. For example:

   Use Jacl:

   set appServer [$AdminConfig list ApplicationServer $serv]
   

   • Use Jython:

     appServer = AdminConfig.list('ApplicationServer', serv) print appServer
     

   where:

   set	Jacl command
   appServer	variable name
   $	Jacl operator for substituting a variable name with its value
   AdminConfig	object that represents the WebSphere Application Server configuration
   list	AdminConfig command
   ApplicationServer	attribute
   serv	evaluates the ID of the server that is specified in step number 1
   print	Jython command

   Example output:

   server1(cells/mycell/nodes/mynode/servers/server1|server.xml#ApplicationServer_1
   

4. Identify the class loader in the appserver and assign it to the classLoader variable. For example:

   • To use the existing class loader that is associated with the server, the following commands use the first class loader:

     Use Jacl:

     set classLoad [$AdminConfig showAttribute $appServer classloaders] set classLoader1 [lindex $classLoad 0]
     

     • Use Jython:

       classLoad = AdminConfig.showAttribute(appServer, 'classloaders') cleanClassLoaders = classLoad[1:len(classLoad)-1] classLoader1 = cleanClassLoaders.split(' ')[0]
       

     where:

     set	Jacl command
     classLoad, classLoader1	variable name
     $	Jacl operator for substituting a variable name with its value
     AdminConfig	object that represents the WebSphere Application Server configuration
     showAttribute	AdminConfig command
     appServer	evaluates the ID of the appserver that is specified in step number 3
     classloaders	attribute
     print	Jython command

   • To create a new class loader,...

     Use Jacl:

     set classLoader1 [$AdminConfig create Classloader $appServer {{mode PARENT_FIRST}}]
     

     • Use Jython:

       classLoader1 = AdminConfig.create('Classloader', appServer, [['mode',  'PARENT_FIRST']])
       

   where:

   set	Jacl command
   classLoader1	variable name
   $	Jacl operator for substituting a variable name with its value
   AdminConfig	object that represents the WebSphere Application Server configuration
   create	AdminConfig command
   Classloader	attribute
   appServer	evaluates the ID of the appserver that is specified in step number 3
   mode	attribute
   PARENT_FIRST	value of the attribute
   print	Jython command

   Example output:

   (cells/mycell/nodes/mynode/servers/server1|server.xml#Classloader_1)
   

5. Associate the shared library that you created with the appserver through the class loader. For example:

   Use Jacl:

   $AdminConfig create LibraryRef $classLoader1 {{libraryName MyshareLibrary} {sharedClassloader true}}
   

   • Use Jython:

     print AdminConfig.create('LibraryRef', classLoader1, [['libraryName', 'MyshareLibrary'],  
     ['sharedClassloader', 'true']])
     

   where:

   $	Jacl operator for substituting a variable name with its value
   AdminConfig	object that represents the WebSphere Application Server configuration
   create	AdminConfig command
   LibraryRef	attribute
   classLoader1	evaluates the ID of the class loader that is specified in step number 4
   libraryName	attribute
   MyshareLibrary	value of the attribute
   sharedClassloader	attribute
   true	value of the attribute
   print	Jython command

   Example output:

   (cells/mycell/nodes/mynode/servers/server1|server.xml#LibraryRef_1)
   

6. Save the configuration changes. See the Saving configuration changes with the wsadmin tool article for more information.

7. In a network deployment environment only, synchronize the node. See the Synchronizing nodes with the wsadmin tool article for more information.
