Hi!
I want to read values from a jsp page that contains something like this:
<form name="selectForm" action="connectRolesToUser.do">
<form:text property="userName"/>
<select name="availableRoles" size="14">
<OPTION VALUE="1">role1
<OPTION VALUE="2">role2
<OPTION VALUE="3">role3
</select>
<html:submit value="Save"/>
</form>
I want the values to appear in an ActionForm so I can store them in a
database in a corresponding Action.
My action-mapping looks something like this:
<action path="/connectRolesToUser"
type="com.mypackage.ConnectRoleToUserAction"
name="connectRoleToUserForm"
scope="request"
input="connectUserRole.jsp">
<forward name="success" path="success.jsp"/>
</action>
The form has been mapped properly in the form-beans section in
struts-config.xml.
My goal now is to read all the rows in the 'availableRoles' above and make
sure they can be found in the form 'connectRoleToUserForm'. The select
'connectRoleToUserForm' has been populated using a java script and another
select box to read stuff from.
The gui look something like this:
|----------| |----------|
| Role1 | | Role3 |
| Role2 | -> | |
| | <- | |
| | | |
|----------| |----------|
I.e. two boxes where the values are moved between them. This logic works
with a simple java script. My problem is that I have spent a day looking for
examples where somebody reads the values from a html:select and access them
in a ActionForm without finding any example clear enough so I can understand
it.
I have seen a lot of half examples on DynaActions, but I assume that it
should be possible to use a ActionForm, and if so, how should the form be
written? I assume something like this:
public class ConnectRoleToUserForm extends ActionForm
{
private String userName = null;
private String[] connectedRoles = null;
// with appropriate setters and getters. But I'm not sure how to write
them
// Should the String[] be initiated in the constructor, and if so, how
do I know what size to set it to?
}
Anyone got any good suggestions or tip to offer?
