Antwort: Re: administration web, struts-config.xml

Hi

I just found out that I can't change the forward "Roles List Setup"
directly to listRoles.jsp because the form bean 'rolesForm' is not set yet.
I have to change the UsersTreeBuilder.java to get rid of the additional
Forwarding. It's not necessary to forward afterwards again to listRoles
("Roles List Setup") because the form bean 'rolesForm' is already
instantianted.

I've just changed the forward request parameter.

TreeControlNode groups = new TreeControlNode
            ("Global Administer Groups",
             "Groups.gif",
             resources.getMessage("users.treeBuilder.groupsNode"),
             "users/listGroups.do?databaseName=" +
             URLEncoder.encode(databaseName) +
             "&forward=" +
             URLEncoder.encode("Groups List"),
             "content",
             false);
        TreeControlNode roles = new TreeControlNode
            ("Global Administer Roles",
             "Roles.gif",
             resources.getMessage("users.treeBuilder.rolesNode"),
             "users/listRoles.do?databaseName=" +
             URLEncoder.encode(databaseName) +
             "&forward=" +
             URLEncoder.encode("Roles List"),
             "content",
             false);
        TreeControlNode users = new TreeControlNode
            ("Global Administer Users",
             "Users.gif",
             resources.getMessage("users.treeBuilder.usersNode"),
             "users/listUsers.do?databaseName=" +
             URLEncoder.encode(databaseName) +
             "&forward=" +
             URLEncoder.encode("Users List"),
             "content",
             false);

This is the same as the above "Roles List Setup" definition since
listRoles.do?forward=Roles+List calls listRoles.jsp.  So it doesn't
matter whether you use forward "Roles List" or to call directly
listRoles.jsp since "Roles List" forwards to listRoles.jsp.
