Version:: $Id: Config.java,v 1.14 2001/07/16 10:08:07 jaco Exp $ $Log: Config.java,v $ Revision 1.14 2001/07/16 10:08:07 jaco jaco: Moved all configuration stuff to MMBaseContext. If needed params not found or incorrect a ServletException with a description isthrown. It's now again possible to not redirect System.out and System.err to a file. Parameters are searched in the webapp (using context-param parameters) when started using a servlet. If htmlroot is not specified MMBaseContext will try to set it to the webapp root directory. Revision 1.13 2001/06/23 16:42:38 daniel changed init to MMBaseContect Revision 1.12 2001/03/06 16:17:35 pierre pierre: added logging Revision 1.11 2000/09/11 20:19:21 case cjr: Added processing of $MOD-Config-REPORT, which displays a report on the configuration, including error notifications, possibly with hints Revision 1.10 2000/08/27 22:30:02 daniel small change for mmdemo Revision 1.8 2000/08/10 21:06:46 case cjr: Added some badly needed comments Revision 1.7 2000/08/06 14:56:18 case cjr: Now tells if no dtd is defined - in this case no validation takes place and previously it was presented as if validation had been done successfully. Revision 1.6 2000/08/06 10:00:42 case cjr: very minor change TODO: - Add code for examples - Add code to check whether database configuration works - Add code for fault oriented results, rather than directory oriented results
Author:: cjr@dds.nl Config module This module analyses the MMBase XML configuration files. LIST functions are: - token=SHOW - type={builders,databases,modules} Returns an list of arrays: $ITEM1 = name of file $ITEM2 = DTD-based syntax check: false, nodtd, true and for builders and databases there is: $ITEM3 = whether the item is active: false, true REPLACE functions are: SHOW, CHECK and ANNOTATE where the next argument is the directory, e.g. 'builders' and the third the name of the file without the .xml extension. SHOW: return a string with syntax colored XML file CHECK: return 1 if validates ok, -1 if not ANNOTATE: return a string with the XML file with errors listed and pointed out visually. Example: $MOD-CONFIG-SHOW-builders-people Additional REPLACE function is: REPORT which has no arguments.

Config

public Config()

Config, a support module for servscan

Method Detail

builderIsActive

public boolean builderIsActive(java.lang.String path)

databaseIsActive

public boolean databaseIsActive(java.lang.String path)

Parameters:: path - Relative path to database mapping file
Returns:: Whether a database mapping file is for the active DBMS

init

public void init()

Description copied from class: Module

Initializes the module. Init can be overridden to read the environment variables it needs.
This method is called by Module.startModule(), which makes sure it is not called more than once. You should not call init() directly, call startModule() instead.

Overrides:: init in class ProcessorModule

reload

public void reload()

Overrides:: reload in class ProcessorModule

onload

public void onload()

Overrides:: onload in class ProcessorModule

unload

public void unload()

Overrides:: unload in class ProcessorModule

shutdown

public void shutdown()

Overrides:: shutdown in class ProcessorModule

getList

public java.util.Vector getList(scanpage sp,
                                StringTagger tagger,
                                java.lang.String value)
                         throws ParseException

Generate a list of values from a command to the processor

Overrides:: getList in class ProcessorModule

Following copied from class: org.mmbase.module.ProcessorModule

Parameters:: sp - the page context; params - contains the attributes for the list; command - the list command to execute.

listConfigDirectories

public java.util.Vector listConfigDirectories(java.lang.String path)

Parameters:: path - Path to root of configuration files
