Hello
in our web site developement project we r using the
followings as development environment

1. JDK 1.3.1_02
2. Tomcat 4.1.29
3. Struts 1.1(frame work)
4. Postgresql 7.4 & pg74.213.jdbc3.jar as JDBC driver
5. Red Hat linux 8 as OS

we have faced a unique problem. in the above JDK
version JDBC driver was not working properly, its not
able to connect to database. If we use JDK 1.4.2 then
the above driver working properly but in this case
STRUTS (mainly iterate tag) was not responsing
properly.

i shall be obliged if u give some guidence regarding
the above problem.

Thanks & Regards

Debashis Dutta

Can you give us more information. What errors are you seeing, the driver
shouldn't be that picky about which jdk (within reason) you use.

If you want to use JDK1.3 you need the jdbc2 version of the driver.

jdbc1 => jdk1.1
jdbc2 => jdk1.2,jdk1.3
jdbc3 => jdk1.4

You have selected a mismatched jvm and jar file.  JDBC 3 requires the 1.4
jvm, for the 1.3 jvm you should use the jdbc 2 jar file.

For your issue with the jdbc 3 driver not working correctly with the 1.4
jvm you have not provided enough information to receive help.  What is the
expected behavior and what are you seeing?  What does the iterate tag do,
and how does that relate to an actual jdbc call?
