Reloading ACL Applications
During the development and testing phase, you can make changes to ACL applications and then issue an Arbortext Publishing Engine HTTP request specifying f=init or click Reload Subprocesses on the Arbortext Publishing Engine web page to reload them from the PE_HOME\custom\init directory.
If there is a syntax error in your custom application, the error is returned in an HTML page in response to the first Arbortext PE sub-process request to perform work (usually from a request containing a f=java, f=javascript, f=vbscript, or f=acl function).
