JNDI Lookup is quite expensive and really there is no sense to search
data source
for each time. It is enough to find it once and save somewhere for
later reuse.
Singleton object is good for such task. For example:
-----
public class DataSourceWrapper{
private static DataSource ds;
public static getDataSource(){
if( DataSourceWrapper.ds == null ){
// well, it is not created yet, so create it here
}
return DataSourceWrapper.ds; // at this point data source will be
allready created and only once
}
}
-----
In hivemind you could create service that wraps data source and inject
it directly in your page... Read more
about it in hivemind docs. ( not a simple task :) )
I am using Tapestry 4 and 3, I have the 4 version installed in tomcat.
When you say that "making lookup each time", is it because the page is
refreshed?
How would I code this using hivemind?
