What is it for?

Joget Workflow provided Bean Shell implementation as several Plugin Types. Please refer to usages section.
BeanShell is a small, embeddable Java source interpreter with object scripting language features written in Java.
BeanShell dynamically executes standard Java syntax in runtime.
By using BeanShell Plugin, you can type in valid Java codes in plugin configuration and the statements will be executed when the plugin is triggered.
No compilation cycle is needed.

What is the code syntax?

Java syntax supported by the version of JDK used
Usage of all libraries that Joget used. For details please refer to NOTICE.txt in the release installer/bundle.
Usage of all Joget Workflow Utility and Service Methods.
Usage of Hash Variable.

Use as Userview Permission

Injected Variables:

- user - User object of current logged in user (org.joget.directory.model.User)
- requestParams - Request parameters map of current HTTP Request (java.util.Map)

Expected Return Object:

- A boolean value to indicate the user is authorized.

Samples:

Check the user is in a group and is an admin user.

Best Practices

1. Only import classes that are needed

Do not use wildcard in import statement. It giving a very bad performance in Bean Shell interpreter to search the whole package and loads it in memory.

Don't:

Code Block

language	java

import java.util.*;

Do:

Code Block

language	java

import java.util.Collection;

2. Do not need to mention the type of element of a collections

Bean Shell interpreter cannot recognise the element type syntax of collections class like Collection, Map, List, Set and etc.

Don't:

Code Block

language	java

Map<String, String> map = new HashMap<String, String>();

Do:

Code Block

language	java

Map map = new HashMap();

3. Indents your script nicely and follows the Java Code Conventions

It will make yours and others life easier to maintain and review the script whenever necessary as Joget Workflow provided flexibility to adapt change quickly.

4. Write your script in functions

If your script is pretty long and some parts of the script are reusable, please make use of function to write your script. It provided better reading and performance.

5. Remember to write some comments

It will helps you and others to understand what is the purpose for the script quickly.

6. Catch the exceptions and give a meaningful message in log.

If you are using a lot of Bean Shell Scripting in your app, a meaningful log message can help you to locate your issue quickly.

Don't

Code Block
try { //do something } catch (Exception e) { LogUtil.error("BeanShell", e, "Error executing script"); }

Do:

Code Block

language	java

try {
    //do something
} catch (Exception e) {
    LogUtil.error("CRM app - Backend userview", e, "Error retrieving user department in Report category permission");
}

7. Consider to make it as a plugin instead of using Bean Shell

If your script need to reuse for multiple times in an app or can be used by others app in future development, please consider to make your Bean Shell script as a plugin instead of copy and paste it multiple times across your app. Bean Shell script is harder to maintain in this case. Imagine that you want to make a change, you will have to update all the places that are using the same script as well. Beside that, a normal plugin implementation will have better performance than a script running by a Bean Shell interpreter.

8. Reuse existing plugins in your code to make it cleaner and easy to maintain

If partial of your script can be done by existing plugins in Joget Workflow, you can reuse the plugin in stead of writting it again.

To reuse a plugin, you can retrieve the plugin using PluginManager, then set it properties and execute it.
