how to move code from jsp to bean when I am using html:select
HI there
I can run my code on jsp page to show data one <html:select> tab, However, I just cannot my it run properly when I move this code in to bean. Below are my jsp code and bean code, could anyone tell me how to convert them please?
Jsp page:
<%@page
import="java.util.*,com.SurveyMaker.ejb.entity.UserCredentialsEntity,com.SurveyMaker.ejb.session.UserCredentialsBean,com.SurveyMaker.ejb.session.UserCredentialsHandler,javax.naming.InitialContext;"%>
<%@taglib uri="/WEB-INF/tld/struts-html.tld" prefix="html"%>
<%@taglib uri="/WEB-INF/tld/struts-bean.tld" prefix="bean"%>
<jsp:useBean id="userCredentials"
class="com.SurveyMaker.userManagement.UserCredentials" scope="session" />
<%
UserCredentialsHandler userCredentialsHandler = null;
try {
InitialContext ctx = new InitialContext();
userCredentialsHandler = (UserCredentialsHandler) ctx
.lookup(UserCredentialsBean.LocalJNDIName);
} catch (Exception e) {
e.printStackTrace();
}
Collection users = userCredentialsHandler.getUsers();
ArrayList list1 = new ArrayList();
for (Iterator iter = users.iterator(); iter.hasNext();) {
UserCredentialsEntity user = (UserCredentialsEntity) iter
.next();
list1.add(new com.SurveyMaker.userManagement.UserCredentials(
user.getId(), user.getFirstName(), user.getLastName(),
user.getUsername(), user.getPassword(), user
.getPrivilage()));
}
pageContext.setAttribute("credentials", list1);
%>
<html>
<head>
<title>Manage User Account</title>
</head>
<body>
<html:form action="manageAccount.do">
<!-- because there are more then one bean, i need to use name to define with bean I am going to use, also need to define it's id at the top -->
<html:select name="userCredentials" property="id">
<html:option value="">Select One</html:option>
<html:options collection="credentials" property="id"
labelProperty="firstName" />
</html:select>
</html:form>
</body>
</html>
