Trying the developer list...

Hi,

I´ve tried answering the following question via the user-list twice and
I have not yet received the solution that I am looking for.  I´ve been
on this for quite some time now and cannot get it to work!

Basically, I want to pass ActionMessages to my JSP using the methods and
classes provided by struts.

Here is the code in my Action:

ActionMessages messages = new ActionMessages();
ActionMessage newMessage = new
ActionMessage("from.my.resourcebundle.text");
messages.add("key.I.pass.to.jsp", newMessage);
saveMessages(request, messages);

// I also tried saving it directly
//request.setAttribute(Action.MESSAGE_KEY, messages);


Now in my JSP I would have the following:

<html:messages id="message" message="true">
    <bean:write name="message"/> <!-- Can I set the property I want?
i.e. property="key.I.pass.to.jsp" -->
</html:messages>

Whenever I put this code into my JSP however, I get the error:

java.lang.NullPointerException
at java.util.Hashtable.put(Hashtable.java:386)
at
org.apache.jasper.runtime.PageContextImpl.setAttribute(PageContextImpl.j
ava:229) at
org.apache.struts.taglib.html.MessagesTag.doStartTag(MessagesTag.java:25
3)

Any help on this matter would be very much appreciated because I really
need to get this working!

Regards,


Michael

Hi,

thanks for your reply.  I just wanted to add that I haven’t actually
tried adding the property attribute to the bean:write tag yet, so the
problem still remains...

Regards,

Michael

No you can't do that with bean:write. If you want a specific property,
specify the property in the html:messages tag and only messages with
that
key will be itereated over.
