iteration of users database in struts-example
Hello everyone, I am trying to modify the struts example to display a list of users at the end of the registration form when someone selects edit registration from the main menu. I have three users in database.xml and this is code i've added to registration.jsp: table logic:iterate id=user name=database tr td align=left test /td /tr /logic:iterate /table This works fine, at the end of the edit registration form, right after the table of subscriptions i get a table of three rows (because i have three users in the database) and each row displays the word test. However, when i try the following code i get an error: logic:iterate id=user name=database tr td align=left bean:write name=user property=username/ /td /tr /logic:iterate I presume i am doing something really wrong, since the current user ca display its username at the beginning of the form. Is there something additional i need to do to get this working besides the registration.jsp changes ?

Re: iteration of users database in struts-example
My guess is that database is a hashmap of some sort, so what you need is bean:write name=user property=value.username/ see http://jakarta.apache.org/struts/struts-logic.html#iterate --m - Original Message - From: Corneliu Rachieru [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Thursday, June 21, 2001 2:46 PM Subject: iteration of users database in struts-example Hello everyone, I am trying to modify the struts example to display a list of users at the end of the registration form when someone selects edit registration from the main menu.
