Module Development

In a script module, I expose a class “test”.
Works fin with static methods.

Into the test class, I would like to access to GatewayContext.getTagManager,
in order to read/write SqlTags.
How to manage it ?

	public void initializeScriptManager(ScriptManager manager) {
		manager.addScriptModule("com.test1", test.class);
