Jython or Jacl are the two scripting languages that you can use for the scripting syntax and that are supported by the wsadmin tool of the WebSphere® Application Server.

Jython

Jython is a general-purpose high-level programming language. It uses code indentation as block delimiters.

• The hash character (#) starts a comment that extends to the end of the line.
• By default, each line is interpreted as one statement.
• You can write multiple statements on one line by separating the statements with semicolons.
• Jython is case-sensitive.

# here is a comment
single_statement(with_arguments)
first_statement_in_line() ; second_statement()
outer statement [first inner] [second inner statement]

A variable can contain an object. In a statement, an object method starts with the object followed by a dot (.), the method name, and arguments that are passed to the method in parentheses ().

# variable 'Object' holds the object to invoke
# invoke the double argument version of the method
Object.method(arg1, arg2)

# and now the single argument version
Object.method(arg)

# there may be a version with three arguments
Object.method(arg1, arg2, arg3)

# invoke the single argument version
# the single argument is provided as a nested statement
# the nested statement invokes the double argument version
Object.method(Object.method(argInner1, argInner2)

Jacl

Jacl is an interpreted language without strong typing. It is a procedural language with some object-oriented concepts that are used by the scripting component.

• The number sign character (#) starts a comment that extends to the end of the line.
• By default, each line is interpreted as one statement.
• You can write multiple statements on one line by separating the statements with semicolons.
• You can nest statements by using brackets [] . The brackets are interpreted like back quotation marks in most AIX® HP-UX Linux™ Solaris shells. The statement within the brackets is run, and its result is substituted in place of the bracketed statement before the surrounding statement is interpreted.
• Jacl is case-sensitive.

# here is a comment
single statement with arguments
first statement in line ; second statement
outer statement [first inner] [second inner statement]

The value of a Jacl variable is accessed by placing a $ in front of the variable name. A variable can contain an object. An object method is started by using the object as the first part of a statement, followed by the method name, and any arguments that are passed to the method. Since there is no strong typing, a method can be overloaded only by varying the number of arguments.

# variable 'Object' holds the object to invoke
# invoke the double argument version of the method
$Object method arg1 arg2

# and now the single argument version
$Object method arg

# there may be a version with three arguments
$Object method arg1 arg2 arg3

# invoke the single argument version
# the single argument is provided as a nested statement
# the nested statement invokes the double argument version
$Object method [$Object method argInner1 argInner2]
