parsing the jndi datasources source code
hi all, I'm looking for the source code/class where the configured jndi datasources are parsed and registred. I'm using Tomcat 4.18 and dbcp I need to understand two features. 1) how a resource is registred in JNDI. 2)how a datasource is instanciated and registred as a jndi resource. thanks in advance. ___ NATEXIS ASSET MANAGEMENT Meissa SAKHO 01 58 19 45 71. . . . . . . . . . . .

JNDI DataSources
I want to use one JDBC connection pool in my tomcat (4.1) instance for all contexts; therefore I configure the DataSource in GlobalNamingResources. In each context I put a ResourceLink so I can obtain the DataSource in my applications. But now I have the problem that I had to execute some SQL statements (e.g. a set role statement or some calls to stored procedures...) on the connection before it will passed to the application. This statements are different from context to context. My current solution is: I wrote a resource factory class, which is configured in every context. It does a JDNI lookup to the global connection pool, gets the DataSource and put it in a wrapper class, which exectures the SQL statetments before getConnection() deliveres the connection to the application. The SQL statements a read in before as resource parameters. This works fine except that global connection pool must be declared in the context with ResourceLink. So the application can also use this DataSource. I want to prohibit that the application can use the original DataSource! Is there a way to use a global resource only in a (context local) resource factory class and prohibit the application to use this global resource? Or do you have a better solution to solve this problem? Thanks, Gernot - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
War Development w/ JNDI Datasources
Hi All,
We are currently developing an application and using CVS to manage our
source code. Our goal is to be able to pull down the project off of CVS and
with a single Ant target, get the application up and running on a local
install of Tomcat.
The problem that has risen is that our DataSources are specified in JNDI
(the server.xml in the {CATALINA_HOME}/conf) and is not something that we
can feasibly park in CVS.
Is there a way to get the DataSources specified without modifying the
server.xml? Or, should we be making an ANT target that loads a second
instance of tomcat using a project specific server.xml, much like what
Cactus describes?
Many Thanks,
Jacob

RE: War Development w/ JNDI Datasources
Howdy,
One idea that leaps to mind is to have ant tokens in your server.xml and
values for those tokens in your build.properties file. Have ant copy
the master server.xml to your local install and fill in the tokens for
your JNDI datasources.
The cactus approach is similar to this and not too bad either.

Re: War Development w/ JNDI Datasources
You can always specify it in a separate context configuration file. Keep
the server.xml generic and put application specifics in context
configuration files.

RE: War Development w/ JNDI Datasources
Howdy,
If you're packing a war, it's META-INF/context.xml. Or you can put
appname.xml in $CATALINA_HOME/webapps as the manager and admin webapps
do.

Re: War Development w/ JNDI Datasources
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/config/context.html
Anything in Context/Context can go in a file outside server.xml, in
the Host's appBase. Tomcat will pick it up automatically.
You name the file app.xml, so if your webapp is myApp, you would put a
file called myApp.xml in the Host's appBase, and the contents of that
file would be the Context element.
The admin and manager Contexts/apps use this method, so every Tomcat
install has an example.

JNDI DataSources
I configured Jakarta-Tomcat-4.1.27 to supply connections of my Oracle Database Server through JNDI Datasource as described in http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jndi-datasource-examples-howto.html All accomplished the tests of JNDI Datasource HOW-TO and everything perfectly worked. Later, reading a magazine of ORACLE finds an article on Six JDBC Tips goes Enterprise Web Application (Setember/October 2002), more specifically with an example on Datasources according to code below: ... Context ctx = new InitialContext(); DataSource ds = (DataSource) ctx.lookup(java:comp/env/jdbc/pequi); conn = ds.getConnection(CELIN,1951174); conn.setTransactionIsolation(Connection.TRANSACTION_SERIALIZABLE); ... My question is if I can pass the user and connection password to the servant of database in the way that is being done above, because in all of the examples of JNDI Datasource HOW-TO user's name and the password are so much defined in server.xml, together with the configuration. When executing the code I am receiving the error message java.lang.UnsupportedOperationException at datasource.OracleDataSource.conecta_datasource(OracleDataSource.java:18) The line 18 of the code is exactly the same in that step the user and the respective password.
