Hi Satya,   I have never encountered such limit, but I truly do not recommend populating so many items in one HTML page (one reason is the out of memory error), another reason is the size of the resulting HTML page, think of a user with modem trying to view such page... too big.   I recommend to divide the data according to initial letter of the customer name, or according to addresses or even according to date they were added to your system (if it is relevant).   These divisions will make the HTML output much smaller, and the required heap memory to be smaller as well.   I would also recommend you to see if you can save HTML output by using CSS instead of HTML attributes, this way you will reduce the HTML output as well.     Hope that helps!

When a single user tries to access this web page it gives a 'Out of memory' exception. When the JVM heap memory is increased it worked fine. But it becomes very slow when running the loadrunner script. simulating multiple users. We are thinking of using some search criteria for fetching the customer names, thus reducing the no of records. Any suggestions are appreciated..   Also,is there any limit on the number of values populated in a combo box in html?   Regards, Satya          To change your JDJList options, please visit: http://www.sys-con.com/java/list.cfm To change your JDJList options, please visit: http://www.sys-con.com/java/list.cfm
