<div style="font-family:Arial, sans-serif; font-size:10pt;">I have used JSP with oracle . so i prefer to use JSP with
postgresql.I <br />have configured the JDBC driver for oracle .Is it ok if i use the same <br />for POSTGRESQL or
shouldi use configure, download and install a <br />seperate JDBC drive for that?? If so which drive should i use??iam
using<br />postgresql 8.1.4. The already configured jdbc is jdk 1.5. which JDBC <br />driver version should i use for
this.howdo i install, configure it and <br />use the driver. should i also include tomcat configuration with this? <br
/>howdo i change the postgresql.conf file.<br />   We have netbeans IDE to work with java . oracle. can the same IDE be
<br/>used for postgresql.<br />   your answer will be really helpful<br /> <br /> Thanks and regards<br /> subha.N <br
