RE: html:frame Problem, very Urgent!
Hi Andrew, we are trying to send objects instead of string variables,request.getParameter() fetch's only string variable. but my requirement is ,i need to retrieve ArrayList object from by using request.getAttribute().its possible by using html:frame??,i am using session.setAttribute() to pass ArrayList Object,but its cause performance problems(tomcat got freezeed,i think because of tomcat VM memory filled up,if restart tomcat its working fine for 3,4 complete executions of application ,then problem is reappearing) Thanks Mohan -Original Message- From: Andrew Hill [mailto:[EMAIL PROTECTED] Sent: Monday, October 20, 2003 12:23 PM To: Struts Users Mailing List Subject: RE: html:frame Problem, very Urgent!

data disappearing in jsp
Hi, In my jsp page I have 5 fields out of which 2 fields are required. When the jsp is submitted I am displaying the error messages for the required fields using Action Error in the form bean's validate method. When the jsp page is displayed with the error messages, the data for the remaining 3 fields is disappearing. Can anyone let me know why this is happening. In the reset method all the fields are made to null. Thanks, Krishna - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: data disappearing in jsp
Max, Thanks for your inputs. But all the fields are declared as properties in the form with setters and getters. These fields are resetted in the reset() method. I tried with commenting them in the reset() method, but this does not seem to solve the problem. Is this a struts default feature that on validation errors when the request goes to jsp page, it does not retain the values of the fields. This will be tedious for a user, that if one required field is missed, he has to retype for all other fields. I found by debug statements in my formbean that in the validate method, the values are available but when the jsp page is populated, the values are not available in the get methods. What can I do to get them back. Thanks, Krishna -Original Message- From: Max Cooper [mailto:[EMAIL PROTECTED] Sent: Tuesday, October 07, 2003 5:23 AM To: Struts Users Mailing List Subject: Re: data disappearing in jsp If the missing fields are display-only, you might need to add hidden fields to carry their values along in the request when the page is submitted so that they will be available on a validation error. reset() is called before the ActionForm is populated with the values from the request, so I don't think it matters what you do to them there. As long as they are in the request (and the names in the HTML form match your ActionForm), they should be populated in the ActionForm when a validation error occurs. -Max - Original Message - From: krishnamohan [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, October 06, 2003 6:10 AM Subject: data disappearing in jsp Hi, In my jsp page I have 5 fields out of which 2 fields are required.

dynamic properties in jsp
Hi, I am working on a page where the user will dynamically add new rows at runtime and there is no limit. This will be on a button 'Add New Option'. So I do not know what properties to create at compile time. If anybody has worked on this type of scenario in struts, pl. help me how to do this or with some code. I am using struts1.1 and tomcat.

Hi,
I am writing a small page based on struts guidelines for creating map-backed

declared a HashMap for collecting values of these fields. However, when I
submit the page, I am getting the error- javax.servlet.ServletException:
