Hmm... I think maybe you are in a bit of fog about all this :-) Calling 'super.init( config )' within a servlet's init method has nothing to do with database connections. Anyway, if you are prepared to post the *exact* bean code that is not working for you, I am prepared to look at it and try to help you. Posting snippets of code is not good enough.

RE: Question on debuggin JNDI/prepared statement in a bean
Not exactly...it is not the same! I have it working with a connection pool, mySQL and JNDI. To keep my reply short it goes like this within the bean: getDBConnection(); // get the connection prepareStatement(); // prepare the statement rs = pstmt.executeQuery(); // execute the query and of course after that I "get" my parameters. In a servlet you have an init() statement that executes only once which you get your db connection in, also you need to call super.init(config), where you don't have to do this in a bean, because it is implicit. (By the way, if someone wants an example, I will post it, but you'll then be my wife.) Next challenge is I have a blob that I set and get, but when I get the blob on my results page, it comes up with something like this @1eb2473 which I assume is an address. Anyone know what know how to get, what's in the address. Maybe open a "stream"?

Exactly the same way as you would anywhere else, so if you have some code working in a servlet, copy it.

Re: Question on debuggin JNDI/prepared statement in a bean
Hey Tom,
When I said your thread was off-topic I didn't mean to imply you couldn't
post your question! Sorry if that's how it came across. Just thought you
should mark it [OT] as Yoav pointed out. It appears I was wrong anyways; I
missed the part about it working in Resin and not in Tomcat.
As for your question, what is it exactly that goes wrong with your app now
that its running under Tomcat and not Resin? Trouble getting the data to
your jsp? Is it not starting up? The code you posted doesn't actually DO
anything so I'm guessing that's just an example you put together to
illustrate what you're trying to do?
Could you post the parts of your Context regarding the jndi resource you are
configuring?

Harry,
Yes the ClassifiedAd and UniqueDateId are two parameters taken
from an html form, the values of ClassifiedAd and UniqueDateId are used
in a prepared statement for substitution of ? and ? the results are then
forwarded to a results jsp, which used the getXXX() to retrieve the
values from the bean.
I have this code working in another form as a Servlet using JNDI
and prepared statements. In the servlet the JNDI connection is made in
the init(blah, blah) and calls the super.init(config) which I
super.init(config) is implicit from reading the Tomcat docs.
The bottom line on this, is how do you set up a JNDI connection
in a bean, use a prepared statement (in a bean), retrieve a resultset
and forward the result for the results jsp to retrieve the value from
the bean.
Finally, I apologize to those who feel this is off topic. I have similar
code working in Resin but for the life of me, I can't get it working
with Tomcat 5 :-( I searched all the archives and can't find a good
example for doing this.

RE: Question on debuggin JNDI/prepared statement in a bean
Harry,
Yes the ClassifiedAd and UniqueDateId are two parameters taken
from an html form, the values of ClassifiedAd and UniqueDateId are used
in a prepared statement for substitution of ? and ? the results are then
forwarded to a results jsp, which used the getXXX() to retrieve the
values from the bean.
I have this code working in another form as a Servlet using JNDI
and prepared statements. In the servlet the JNDI connection is made in
the init(blah, blah) and calls the super.init(config) which I
super.init(config) is implicit from reading the Tomcat docs.
The bottom line on this, is how do you set up a JNDI connection
in a bean, use a prepared statement (in a bean), retrieve a resultset
and forward the result for the results jsp to retrieve the value from
the bean.
Finally, I apologize to those who feel this is off topic. I have similar
code working in Resin but for the life of me, I can't get it working
with Tomcat 5 :-( I searched all the archives and can't find a good
example for doing this.
TIA Tom K.

Question on debuggin JNDI/prepared statement in a bean
I am frustrated trying to debug a prepared statement within a bean; what
am I doing wrong?; ANY clues appreciated…
It is not throwing any exceptions yet I methodically went over the code;
granted this is the first time I used beans versus servlets.
Can anyone point me to a good example (JNDI, JSP, JavaBean, Resultset)
Code within bean:
private void prepareStatement(){
try{
Context env = (Context) new
