Configure a shared library using scripting

 

Procedure

1. Start wsadmin

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

   • Jacl:

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

   • Jython

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

   where:

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

   Example output:

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

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

   • Jacl:

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

   • Jython:

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

   where:

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

   Example output:

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

4. Identify the application server from the server and assign it to the appServer variable. For example:

   • Jacl:

     set appServer [$AdminConfig list ApplicationServer $serv]
     

   • Jython

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

   where:

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

   Example output:

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

5. Identify the class loader in the application server 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:

     • Jacl:

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

     • Jython

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

     where:

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

   • To create a new class loader, issue the following command:

     • Jacl:

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

     • Jython

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

   where:

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

   Example output:

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

6. Associate the shared library that you created with the application server through the class loader. For example:

   • Jacl:

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

   • Jython

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

   where:

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

   Example output:

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

7. In a network deployment environment only, synchronize the node.
