So, you could do something like this: bean:define name=temp type=java.lang.String/collaborator.do?mode=editcode=%=code%/bean:define html:link page=%=temp%Edit/html:link or better yet this instead html:link action=collaborator.do?mode=editcode=%=code%Edit/html:link To pass parameters to URLs built from the action attribute, you can use paramId, paramName, paramProperty, and paramScope to pass a single parameter, or name (and optionally property) to identify a Map whose keys are parameter names and whose values are corresponding parameter values. See http://jakarta.apache.org/struts/userGuide/struts-html.html#link for details. Actually, you can use these to pass parameters to any url, but if you use the action attribute, this is the only way to do it. For what you define above, you may prefer to establish the mode=edit state by using a different ActionMapping. Something like: action path=/CollaboratorEdit parameter=edit type=com.example.CollaboratorAction ... / action path=/CollaboratorView parameter=view type=com.example.CollaboratorAction ... / Your action class can use mapping.getParameter() to find out whether it's in edit or view mode just as easily as it could consult the mode property of an ActionForm (or the mode request parameter). In my opinion, this is more elegant, and it saves the hassle of appending multiple parameters in html:link using a Map. The c:url tag in the JSTL supports a c:param subtag for adding an arbitrary number of parameters to a URL. Of course, it doesn't know how to dereference an action path. There's been some talk about adding a similar tag in Struts, but no one has been motivated to write it yet.

Re: html:link question (for a relative newbie)
A quick hack you can do is:
%java.util.HashMap ha = new java.util.HashMap(); ha.put(mode,edit);
ha.put(code, code); pageContext.setAttribute(linkParams,ha);%
html:link href=collaborator.do name=linkParamsEdit/html:link
I usually build my link hashmap in the setup action for the jsp, but you can
do this.

I cannot seem to get this to work
html:link
page=/collaborator.do?mode=editcode=%=code%Edit/html:link
or better yet this instead
html:link
action=collaborator.do?mode=editcode=%=code%Edit/html:link
but the %=code% is not picking up the value of code, instead it is
putting %=code% in its place. That all makes sense why, but is there
a
way I can get at a expression using Struts tags like I can using the code
below with a hard coded HREF ('cuse it works fine there but is not what I
want).
A href=logon.jsp?task=deletecode=%=code%Delete/A
All else works fine, I realize that I could be chaining actions or some
other do not do but I am under a bit of a time crunch (as always... :).
TIA, Steve

RE: html:link question (for a relative newbie)
If you are not opposed to using the JSTL standard library
I personally have a difficult time keeping track of the parameters
and values using the other syntax.
c:url value='/collaborator.do' var='collaboratorURL'
c:param name='mode' value='edit'/
c:param name='code' value='${code}'/
/c:url
html-el:link href='${collaboratorURL}'
Edit
/html-el:link
