Script Compilation

Depending on the ScriptEngine of your choice you have various options to compile a script

• transforming the script into an AST (abstract syntax tree) on the fly
• compiling the script into Java bytecode on the fly thereby creating a Java class dynamically
• precompile the script to Java bytecode thereby creating a Java class file

Script Management

The scripts are managesd by the Fulcrum ResourcManager Service. This gives you the locator functionality, optional decryption and location transparency

Locator

The locator gives you easy customization of scripts. Let's say you would like to invoke the script 'foo.js' for a customer 'BAR' using the following script layout

        
scripts
  -- foo.js
  -- BAR
     -- foo.js
        
      

In the case of invoking 'foo.js' the script 'foo.js' would be executed. In the case of invoking 'BAR/foo.js' the script 'BAR/foo.js' would be executed. In the case of invoking 'FOO/foo.js' the locator is looking for 'FOO/foo.js'. Since it isn't found it steps up a directory to execute 'foo.js'. The trick was taken from the Fulcrum XSLT service which uses a simlilar fallback mechanism.
