[Babeldoc-devel] Modification to com.babeldoc.sql.config.SqlConfigService

[<ek...@ba...>]

In addition, I will be attempting to have my class utilize a database 
connection pool from Weblogic ... which I believe is accessible via JNDI 
... rather than the straight database connection.  Additionally, I will 
need to clear the cache whenever a database update occurs ... so I will be 
calling com.babeldoc.core.config.ConfigService.clearCache( ) upon 
successful execution of 
com.babeldoc.sql.config.SqlConfigService.saveConfig( ).

Uh oh ... I just realized a problem ... clearCache( ) is only going to 
clear the cache on the Weblogic instance that did the update ... in a 
clustered environment, any other WL servers would not have their cache 
cleared.  This will not work for me.  I need to have this "cache" sitting 
in a centralized location ... such as an entry in a common JNDI tree ... 
that is read by each WL Server instance whenever it needs information ... 
when a database update occurs, the clearCache( ) method would need to 
destroy the JNDI tree object ... ughhh.

Any better ideas?

Subject:        Modification to com.babeldoc.sql.config.SqlConfigService

Gents,

I have a few requirements that are going to cause me to diverge from the 
codebase with regard to the SQL Configuration Service.  My needs are very 
specific to my environment and should not be applied to the babeldoc 
codebase.

That being said, I will be either Modifying or Extending 
com.babeldoc.sql.config.SqlConfigService.  My preference is to extend it. 
I will be calling the new class 
com.bankofny.iecc.alt.sql.config.SqlConfigService.

I am attempting to place in my new class only those things that will 
change from the base class (obviously).  I have encountered two things 
that will cause me a little grief, and I'm wondering if we can modify them 
in the babeldoc codebase.

1. The instance variables "dbName", "dbPasswd", dbDriver", and "dbUrl" are 
all package-friendly.  Is it possible for us to make these Protected, so 
my subclass can access them?
2. The method "setString" is package-friendly.  Is there any reason this 
cannot be made Protected (or even Public)?

If you have no objections, I will make the modifications to the class and 
check it in with CVS to sourceforge.  Please advise.

Just so you know, I plan to override the following methods in my new 
class:
-- getConfig(String name)
-- setString(String name, String value)
-- saveConfig(String name, IConfig config)
