Scripting is a non-graphical alternative that you can use to configure and manage The wsadmin tool supports two scripting languages: Jacl and Jython. Creating Java Application Control Language (JACL) Scripts. This tutorial contains the following sections: This tutorial covers how to create JACL scripts.

Run the array command with an argument. The final type of substitution done by the Jacl interpreter is backslash substitution. Do not use redirection when using the exec command of the Jacl language.
Variables introduced in the procedures exist only for the duration of the procedure call. The second argument is the name of a variable that contains the result of the command or an error message if the command raises an error. The syntax rules are the same as for commands. The pattern does not have to match the whole string.
Jaacl can also group all the pattern-body pairs into one argument: To make them visible, declare the variables globally using the global command. The following figure illustrates the major components involved in a wsadmin scripting solution: However, you can use other scripting languages to retrieve a value for a variable.
Statements can have any indentions.

The wsadmin tool does not apply to Liberty. Once the expr command computes the answer, it is formatted into a string and returned. If the pattern that is associated with the last body is defaultthen the command body is started if no other patterns match.
You do not have to declare Jacl variables prior to using them. The WebSphere Application Server wsadmin tool provides the ability to run scripts. It is easy for both Jacl and Jython to call Java directly. For example, you need to know the APIs that handle regular expressions in Jython, such as the module re and the model re methods.
Some documentation is available here. The command body runs one time for each element in the loop with the loop variable having successive values in the list.
Using wsadmin scripting with Jacl
In Jacl, strict indention is not required. The second argument is a boolean expression tutprial determines if the loop body runs. The wsadmin script language defines five types of management objects, such as AdminConfig. The catch command takes two arguments, for example:. If there is more than one server, it prints all of the servers:. Internally an array is implemented with a hash table. The general syntax of the string command is the following:.
You can get the substring per the pattern order in the regular expression.
Replaces elements i through j of list with the args. You might need to test for the existence of the variable because the incr parameter requires that a variable exist first, for example: The parsed arguments can then be jxcl correctly by other statements. Use the error message to determine the cause of the error and where the error occurred.
A profile script is a script that runs before the main script, or before entering interactive mode. You must start the wsadmin scripting client before you perform any other task using scripting. Settings based on any other code page might cause the scripts to fail.
Getting started with wsadmin scripting
When you run a proc command, a local namespace is created and initialized with the names and the values of the parameters in the proc command. You do not need to change any of your existing applications and scripts that use Jacl; but you should consider using the strategic alternative for new applications.
The return command is optional in this example because the Jacl interpreter returns the value of the last command in the body as the value of the procedure. This approach makes all of the files that are created by the user readable by other users.
