TC 5.5 and commons-dbcp

[Robert Bateman <bo...@sequoiallc.com>]

I'm in the process of moving an application that is in production today
on a TC 4.1.30 deployment over to 5.5.

So far, everything has moved without too much trouble.  That is, until I
get to the use of commons-dbcp in the code.  The code uses
BasicDataSource to interface to commons-dbcp.

Under 4.1.30 (and I believe 5.0 as well...) I can do:

Context ctx = new InitialContext();
BasicDataSource ds = (BasicDataSource)ctx.lookup("jndi string");

And I would get a data source.  Under 5.5.7 and 5.5.9, ctx.lookup()
throws an Exception.  BUT, neither getMessage() nor getCause() return
anything legit (both return NULL).


My setup requires me to run TC with -security.  Using -verbose:class and
-Djava.security.debug=access,failure (THANKS Jon Wingfield!), I've
determined that TC 5.5.7 and 5.5.9 are loading everything and that I
have permission to access the various modules


[Opened /usr/java/Tomcat/common/endorsed/commons-dbcp-1.2.1.jar]
[Opened
/usr/java/Tomcat/common/endorsed/mysql-connector-java-3.0.12-production-bin.jar]
access: access allowed (java.io.FilePermission
/usr/java/Tomcat/common/endorsed/commons-dbcp-1.2.1.jar read)

access: access allowed (java.io.FilePermission
/usr/java/Tomcat/common/lib/naming-factory-dbcp.jar read)
[Loaded org.apache.tomcat.dbcp.dbcp.BasicDataSourceFactory]


But I don't get anything legit out of ctx.lookup()  :(

I'd like to see if I can debug this to isolate *where* things are going
a-stray...  Can anyone set my on the correct path?  A search of this
list hasn't revealed anything *other* than my JNDI string is incorrect
(I can deploy the same WAR to 4.1.30 and 5.0 and it works - so I suspect
my environment and possibly TC 5.5 and the -security setting...)


Thanks in advance!


Bob

Hi Robert,

the JNDI resource configuration has changed in 5.5. Check out the docs 
for an example: 
http://jakarta.apache.org/tomcat/tomcat-5.5-doc/jndi-datasource-examples-howto.html.

Also Tomcat 5.5 has changed the commons-dbcp-x.x.x.jar to 
naming-factory-dbcp.jar. And the org.apache.commons.dbcp.BasicDataSource 
is now moved to org.apache.tomcat.dbcp.dbcp.BasicDataSource.
