Description
Defines the JSR-223 "Scripting for the Java Platform" Script engine/context initializers.
It's mostly referenced by the Script element.
Its sub-elements are:
ScriptCache
Defines the script file cache configuration.
Its attributes are:
| Attribute | Type | Description |
|---|---|---|
| base-path | optional | Base path for script files access. Default to $GV_HOME/scripts. |
ScriptEngines
Defines the engine/context initializers.
ScriptEngine
Script Engine initializer. Usable script engine must at least have MULTITHREADED capability. If the script engine implements Compilable interface and the script DESN'T USE placeholders, the script itself is precompiled and reused for better performances. Script Engines dependency libraries must be prensent into GreenVulcano® ESB classpath.
Its attributes are:
| Attribute | Type | Description |
|---|---|---|
| type | fixed | script-engine. |
| lang | required | Script Engine language. |
| default-context | optional | If defined, refers to an included BaseContext to be used as default context initialized for the given language scripts. |
Its sub-elements are:
- Description
- BaseContext
BaseContext
Basic Context initializer. A given context can contains pre-configured set of objects/functions, to be used in specific script executions.
Its attributes are:
| Attribute | Type | Description |
|---|---|---|
| name | required | Initializer name. |
| file | optional | This attribute is the name of a file containing the script to parse/execute for initializing the context. The file path must be relative to $GV_HOME/scripts. |
Follow an examples configuration of multiple scripting engines/context:
<GVScriptConfig name="SCRIPT" type="module">
<ScriptCache base-path="sp{{gv.app.home}}/scripts"/>
<ScriptEngines>
<ScriptEngine lang="ognl" type="script-engine"/>
<ScriptEngine lang="groovy" type="script-engine"/>
<ScriptEngine default-context="gvesb" lang="jruby" type="script-engine">
<BaseContext name="basic"/>
<BaseContext file="jruby/initscope.rb" name="gvesb"/>
</ScriptEngine>
<ScriptEngine default-context="gvesb" lang="js" type="script-engine">
<BaseContext file="js/initscope.js" name="gvesb"/>
<BaseContext name="basic"/>
<BaseContext file="js/initscope.js" name="JavaScriptRetriever"/>
</ScriptEngine>
</ScriptEngines>
</GVScriptConfig>
