Confused about Drop down lists (database generated)

Rate this Message:
All the drop down lists in my application need to be generated from the
database. Some of these lists will be needed for more than one JSP. So, in order to work with the <s:select> tag I am building an action for each list. I know this has to be wrong. Especially because some JSP's will need multiple drop down lists. What is the best way of doing this in struts 2.1.8? Here is an example create method that I am using and the JSP that feeds it. Should I be using a better way to get to create from a JSP? I want to be able to use the roles drop down in multiple JSP's. public String createUser() { User user = new User(); user.setUserName(userName); user.setPassword(password); user.setFirstName(firstName); user.setLastName(lastName); user.setPhone(phone); user.setEmail(email); service.createUser(user); String userId = service.getUserId(user.getUserName()); roleUser = new RoleUser(); roleUser.setRoleId(roleId); roleUser.setUserId(userId); service.createRoleUser(roleUser); roleUser = null; user = null; return SUCCESS; } <%@ page contentType="text/html; charset=UTF-8"%> <%@ taglib prefix="s" uri="/struts-tags"%> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <s:head /> <body> <font color="red"><html:errors /></font> <s:form action="createUserAction"> <div class="inputs"> <s:hidden name="id" /> <s:textfield label="User Name:" name="userName" /> <s:password label="Password:" name="password" /> <s:password label="Repeat Password" name="password2" /></div> <s:textfield label="First Name:" name="firstName"></s:textfield> <s:textfield label="Last Name:" name="lastName"/> <s:textfield label="Email:" name="email"/> <s:textfield label="Phone:" name="phone"/> <s:select label="Role:" name="roleId" list="roles" listKey="id" listValue="name"/> <s:submit></s:submit> </div> </s:form> </body> Elizabeth Sommers Build and Release Engineer Pragmatics, Inc. 703.761.4033 www.pragmatics.com Practical.

Just add something like the following to the methods that execute before JSP
processing. this.roles = service.getRoles(); You might also look into the Preparable interface, depending on application design. -Brian On Thu, Nov 12, 2009 at 8:02 AM, Sommers, Elizabeth <SommersE@... > wrote: > All the drop down lists in my application need to be generated from the > database.

You can use org.apache.struts2.util.ListEntry , a default object to hold key
value in Roles list box for JSP page dropdowns. <s:select label="Role:" name="roleId" list="roles" /> Regards, Raghuveer Vellanki -----Original Message----- From: Sommers, Elizabeth [mailto:SommersE@...] Sent: Thursday, November 12, 2009 7:32 PM To: Struts Users Mailing List Subject: Confused about Drop down lists (database generated) All the drop down lists in my application need to be generated from the database.
