yes, clearly a context file for each web app is a better / wiser choice, thanks for the advice ! - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Great, that's always good to hear. Also consider providing your own context xml for each app with the war file, might save you some time in server restarts. Unless you changed server.xml through the administrative interface. On Wed, 21 Jul 2004 10:24:21 +0800, Koon Yue Lam [EMAIL PROTECTED] wrote: Tthanks for the help for all of u !

Re: Datasource problem again..
Good point.
I've done the same, ie setup a DefaultContext within the Host of
server.xml, and defined my data-source there.
I've still got a context.xml, but it's now down to just a couple of lines
ie to specify docBase, path and a logger.
It looks like this now:
?xml version='1.0' encoding='utf-8'?
Context docBase=/webapps/isurvey path=/isurvey reloadable=true
swallowOutput=true
Logger className=org.apache.catalina.logger.FileLogger
prefix=isurvey_log. suffix=.txt timestamp=true/
/Context
Just to make it clear what this is all about, you don't need to define a
Context in your server.xml.
In my case, my app is called 'isurvey', so I defined a file called
'isurvey.xml' containing the Context above.
I placed this file in {tomcat home}/conf/Catalina/localhost/ , and tomcat
was able to automatically detect the app.

John

Re: Datasource problem again..
I tried using the datasources tags in struts-config.xml, couldnt get it work so I modified the server.xml in tomcat/conf directly. Just add a context element as follows in your server.xml This is my configuration: Context path=/wrap docBase=C:\tomcat5\webapps\wrap reloadable=true Resource name=jdbc/WrapDB auth=Container type=javax.sql.DataSource/ ResourceParams name=jdbc/WrapDB parameter namefactory/name valueorg.apache.commons.dbcp.BasicDataSourceFactory/value /parameter !-- Maximum number of dB connections in pool. Make sure you configure your mysqld max_connections large enough to handle all of your db connections. Set to 0 for no limit. -- parameter namemaxActive/name value200/value /parameter !-- Maximum number of idle dB connections to retain in pool. Set to 0 for no limit. -- parameter namemaxIdle/name value10/value /parameter !-- Maximum time to wait for a dB connection to become available in ms, in this example 10 seconds. An Exception is thrown if this timeout is exceeded. Set to -1 to wait indefinitely. -- parameter namemaxWait/name value20/value /parameter !-- dB username and password for dB connections -- parameter nameusername/name value(*place your username here) /value /parameter parameter namepassword/name value(*place your password here)/value /parameter !-- Class name for oracle JDBC driver -- parameter namedriverClassName/name valuecom.microsoft.jdbc.sqlserver.SQLServerDriver/value /parameter parameter nameurl/name valuejdbc:microsoft:sqlserver://(***place your URL here)/value /parameter /ResourceParams /Context Hope this helps. -Asif - Original Message - From: Koon Yue Lam [EMAIL PROTECTED] To: Struts Users Mailing List [EMAIL PROTECTED] Sent: Monday, July 19, 2004 12:46 PM Subject: Datasource problem again..

Re: Datasource problem again..
I recall reading about a month ago that setting up of data-sources in struts-config was purely for some backwards-compatability issue, and was no longer advised. I haven't bothered to do it. I set up my data source in a server.xml context, and it works fine. Like you I'd prefer to have server-wide scope on the data-source rather than context scope, but I haven't spent any time on it yet. One option may be to configure the data-source as part of the DefaultContext. I believe all other contexts inherit from a DefaultContext if one is configured - but like I said, I haven't tried it yet.

Re: Datasource problem again..
If you're auto-deploying and can get the DefaultContext to work for you, then that's what I'd do. (I'm not auto-deploying, so my case isn't so straight-forward). You always have the fall-back of configuring Context datasources if you run into trouble. There's an example of configuring a DefaultContext with a datasource here: http://jakarta.apache.org/tomcat/tomcat-4.1-doc/config/defaultcontext.html This is how I've configured my data-source: Context docBase=/webapps/isurvey path=/isurvey reloadable=true Resource name=jdbc/as400 auth=Container type=javax.sql.DataSource/ ResourceParams name=jdbc/as400 parameter namemaxWait/name value5000/value /parameter parameter namemaxActive/name value4/value /parameter parameter namepassword/name value**/value /parameter parameter nameurl/name valuejdbc:as400://localhost;naming=system/value /parameter parameter namedriverClassName/name valuecom.ibm.as400.access.AS400JDBCDriver/value /parameter parameter namemaxIdle/name value2/value /parameter parameter nameusername/name value**/value /parameter /ResourceParams /Context And this is how I use the data-source in java: Context ctx = new InitialContext(); Context envCtx = (Context) ctx.lookup(java:comp/env); DataSource ds = (DataSource) envCtx.lookup(jdbc/as400); I'd be interested to know how you get on with this.

Re: Datasource problem again..
You can still have a context regardless of whether you auto deploy or not. See that snippet that jthopmson sent? You can deploy that with your war file, I think the name of the xml has to match the war file name if I'm not mistaken. Then you will have a context properly setup with the datasource.
