Hello,
Question regarding Tomcat 5.5.7 and the JNDI Datasource:
It seems like either the web documentation for Tomcat 5.5 or the
implementation is incorrect regarding the use of JNDI Datasources.
In this page:
<http://jakarta.apache.org/tomcat/tomcat-5.5-doc/jndi-datasource-examples-howto.html>
the "Resource" element configuring the DataSource is put inside the "Context"
element.
However, I have tried to set up a DataSourceRealm that is configured
using said "Resource"

Out of luck? Bugs related to other Tomcat versions helped out:
<http://issues.apache.org/bugzilla/show_bug.cgi?id=24723>
<http://issues.apache.org/bugzilla/show_bug.cgi?id=24836>
I put the "Resource" element inside the "GlobalNamingResources" element,
described here:
<http://jakarta.apache.org/tomcat/tomcat-5.5-doc/config/globalresources.html>
...and it worked!
Maybe the documentation should tell people to set up the "Resources" in the
"GlobalNamingResources"? Probably not though -- there might be some other
reason why
it didn't work. I tried "useNaming=true" for the "Context" according to
<http://jakarta.apache.org/tomcat/tomcat-5.5-doc/config/context.html> but
no go :-((
Additionally:
The 'factory' attribute of the 'Resource' element is mentioned nowhere... o_O
which is **BAD** because w/o the factory value the Realm Authentication seems to
reduce to 'Access All Areas' - you don't get no error in the catalina log
either.
