Instantiating and executing the JLI

The following sample code shows how to instantiate and execute the Jython Line Interface (JLI):

01 #!/usr/bin/env jython
02 import bladelogic.cli.CLI as blcli
03 jli = blcli.CLI()
04 jli.setServiceProfileName("defaultProfile")
05 jli.setRoleName("BLAdmins")
06 jli.connect()
07 cmd = [NameSpace,blcliCmd,Arg1,…,ArgN]
08 returnObject = jli.run(cmd)
09 # returnObject has various methods and properties.
10 # The following 'if' statement demonstrates the important three
11 if(returnObject.success()):
12     print returnObject.returnValue
13 else:
14     print returnObject.getError()

Here is a brief analysis of the preceding lines. See Basic Jython programming principles for more information about underlying concepts.

Line 1: Specify the Jython interpreter.
Line 2: Import the CLI class from the bladelogic.cli module.
Line 3: Create an instance of the CLI class named jli.
Line 4 & 5: Set the profile and role for a BLCLI connection to the application server. This connection is used by the script until it finishes running.
Line 6: Call the jli.connect function to establish a connection to the application server using the credentials acquired using blcred for making CLI calls.
Line 7: The JLI accepts BLCLI commands as arrays (lists). This line demonstrates a pseudo-command in the JLI.
Line 8: The jli.run(cmd) statement accepts the array variable cmd and returns a BLCLI return object to the returnObject variable.
Line 9 & 10: Comments.
Line 11: Test for the successful execution of the JLI command processor. If the command executed successfully, returnObject.success() returns 1; if unsuccessful, returnObject.success() returns 0.
Line 12: If .success() equals 1, this line executes, printing the return value of the executed command.
Line 13: If .success() equals 0, this line begins the else suite of the if…else clause.
Line 14: If .success() equals 0, executing the else suite, this line prints the error retrieved from the unsuccessful execution of the JLI processor.
