My application starts of with an index.jsp page where the user inputs his name and email address, this call an action 'createCookie' where the details are stored in a cookie.
I need the details to be read from the cookie and displayed to the user the next time he opens the webpage.
The relevant code int index.jsp
<logic :-P resent cookie="cename"> <bean:cookie id="namecookie" name="cename"/> <bean:write name="namecookie" property="name"/> <bean:write name="namecookie" property="value"/> <html:text property="ename" size="50" maxlength="50" [B][I]value="<bean:write name="namecookie" property="value"/>"[/I][/B]/> </logic :-P resent>
The revelant code in createCookie.java
Cookie nameCookie = new Cookie("cename", briefingInfoForm.getEname()); nameCookie.setMaxAge(10000); Cookie emailCookie = new Cookie("ceemail", briefingInfoForm.getEemail()); emailCookie.setMaxAge(10000); response.addCookie(nameCookie); response.addCookie(emailCookie);
The code in bold italics in index.jsp in the text input box is where I am getting the error. If any one could point me the right way to do this, it will be great.
The error I get is "attribute nameCookie has no value", even though the line above that prints out the value of the nameCookie.
Thanks a bunch

Code, simply remove the "value" attribute. In a Struts <html:text> tag, the value comes from the property attribute, and the value attribute generally does not need to be specified.

In the above scenario, if we want to display the cookie value in a text-box (instead of read-only label), how do we display the same?
The below code doesnt display it in the text-box, even though until the previous line, the cookie value is coming... can someone point out my mistake?
<html:text name="logonForm" property="username" size="16" value='<bean:write name="unameCookie" property="value"/>' />
I think Merrill said something about
...the value comes from the property attribute..
Does that mean the cookie name & the text-box name must be same??
My jsp code is -
<logic :-P resent cookie="edm.unameCookie"> <bean:cookie id="unameCookie" name="edm.unameCookie"/> <bean:write name="unameCookie" property="value"/> <html:text name="logonForm" property="username" size="16" value='<bean:write name="unameCookie" property="value"/>' /> </logic :-P resent> <logic:notPresent cookie="edm.unameCookie"> <html:text name="logonForm" property="username" value="" size="16"/> </logic:notPresent>
