RE: Cannot find message resources underkeyorg.apache.struts.action.MESSAGE
I have not of experience with struts, but I installed struts 1.1b3 so I could try out the message-resources as well. I had a lot of trouble with my vm crashing on the struts <bean:resource> and <bean:message> tags, but I suspect that could have been caused by some incompatibility with the new tags and JBuilder 4.0.
One thing I did notice was that even though you didn't specify the _en suffix in the property name file in struts-config.xml it still used it to access the properties file. I assume it uses the default locale. I have 2 properties files from 2 locales (properties_en.properties and properties_fr.properties). Also I set Locale to "true" in web.xml under the Action Servlet configuration.

That looks right. It still doesn't work?

You should have a struts "default" bundle. You should have (using your
example) a "properties.properties", then "properties_en.properties" for
messages specific to English users and "properties_fr.properties" for
messages specific to Frech speaking users.
This allows you to deploy your application on any server in the world
(where the default locale on the actual server may not be "_en")
So, if you want the "default" language for your application to be
English, then rename "properties_en.properties" to
"properties.properties" and it will work fine everywhere.

Re: Design Question Regarding Connection Pooling
Posted by Vic Cekvenich <vc...@basebeans.com>.
Oh god.
DataSource has little to do with Struts.
Containers and app servers provide connection pooling.
PostgreSQL is great! and it's JDBC 3.0 compliant, and provides a
PooledDataSource as do most other JDBC drivers and DB's out there
(mySQL, Oracle, MSSQL, etc.)
So a good practice is to create a connection pool in Tomcat, etc.
Working example server.xml for tomcat (also same place has example for
Orion and Resin & working example of J2EE security:
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/basicportal/bP/WEB-INF/doco/server.xml.tomcat4
Just modify it.
Connections in action? Maybe connection in DAO.
Ex:
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/basicportal/bP/WEB-INF/src/war/org/apache/scaffoldingLib/base/DAOIBaseHelper.java
See how I have a static grab on to a data source?
JNDI done once, application wide.
Conn.close()? I don't.
It is a good idea to use one of many DAO implementations out there. I
use iBatis.com db layer(becasue it is SQL based), others use Hibreante,
OJB, etc. Pick one.
One should not be coding applications at that low JDBC level anymore.
For one DAO's provide caching, and transctions and .... they just easy
to talk to db.
Let the DAO worry about all the low level stuff, like connection
release, transactions, flushing the data cache when CRUD, etc.
