I think i solved it because I put a <logic:present> tag and now it works:
I wrote this:
logic:present name="userList"logic:iterate id="users" name="usersList"
scope="request" type="com.genausal.entity.Users"/
/
/tr>a
href="consultuseradmin.do?passport_id"=bean:writename="users"property="passport_id"/>"bean:write
name="users" property="passport_id"/a/trtrbean:write name="users"
property="first_name"//trtrbean:write name="users"
property="country"/trlogic:iterate/logic:present
I write them here without < > because it's the unic way to see them

Asunto: Re: javax.servlet.ServletException: Cannot find bean usersList in scope
request
Ok ... your email client is weird in how it put's html in, but that's a
different subject. The stack trace indicates that logic:iterate can't
find the collection you stored in "usersList". You could wrap the whole
table in logic:present tag and then have some error message in a
logic:notPresent tag to better diagnose what's going on. Are you sure
your action is being executed?
