DataSource defined on webApp context are accessed by similar url :
java:comp/env/jdbc/dataSourceName.
Now.
Is't possible use with a url datasource that are only defined in
GlobalNamingResources (in server.xml) using the name ???

Then you might want to incorporate your own DBCP pool and a brief
config page in your webapp.
- Store config data in a properties file inside WEB-INF or somewhere
else.
- Use a ServletContextListener to initialize the DataSource and store
it in the ServletContext.
- Implement a secured jsp or servlet to configure DBCP at runtime and
store the result in the config file
- On change have the jsp or servlet close down the existing DBCP and
replace it with a new one.
- Update all the other jsps and servlets to get their DataSource from
the ServletContext
That's what I'd do at least.

I have a particular application who make select query and show results.
The dataSource are dinamic and defined by the administrator, not know
at develop time.
I want to be able to use the tomcat dataSource to use the pool...

I don't think you can just define a global datasource and not make a
reference to it in the context.xml file.

Hi all,
i use Tomcat *5.5.17 *my question is quite simple: it's possible to
use a dataSource that are not defined on webApp context???
I define the dataSource on server.xml as follow:
<Resource auth="Container" driverClassName="DriverClassName"
validationQuery="select count(*) from table"
maxActive="100" maxIdle="30" maxWait="10000"
name="jdbc/DataSourceName"
password="pass" type="javax.sql.DataSource"
url="jdbc:DBMS://ServerName:Port/dbName" username="user"/>
After, i want to be able use this dataSource on java program...
Normally this is the java code to get the dataSource:
InitialContext initialContext = new InitialContext();
DataSource ds = (DataSource)
initialContext.lookup("jdbc:DBMS://ServerName:Port/DbName");
conn = ds.getConnection();
If the dataSource is not defined on context (<ResourceLink
name="jdbc/DataSourceName" global="jdbc/DataSourceName"
type="javax.sql.DataSource"/>) the code return an exception:
Name DataSourceName is not bound in this Context.
Any Suggestions????
Robert.
