<div>
try using a CachedRowSetImpl instead of a ResultSet<br />
<br />
you will need to download the rowset.jar file downloaded from <br />
<br />
<a href="http://sourceforge.net/project/showfiles.php?group_id=27749" rel="ugc">http://sourceforge.net/project/showfiles.php?group_id=27749</a><br />
<br />
you will need to include this file under <br />
web-inf/lib/rowset.jar<br />
<br />
also you will need to include this line<br />
<br />
&lt;%@ page import=&quot;com.sun.rowset.*&quot; %&gt;<br />
<br />
to the top of your jsp<br />
Hope that helps,<br />

my web application running on Tomcat and Oracle has encountered some problems that when user constantly update, they will get lock out and I have re-start the web server to let them start the application again. But, this constantly happened. so, I check the log from Tomcat and see this error, I wonder if anyone could offer advice about how to fix this problem? Is this related to Oracle? thanks.

JavaServer Pages (JSP) allow the development of dynamically generated web pages. It uses the Java programming language; JSP pages are translated into servlets at runtime, with each servlet being cached and reused until the JSP is modified. JSP allows Java code to be interleaved with static web markup content, so the resulting page can be compiled and executed on the server to deliver the content.
