Hi,
check the struts doc for html-tags:
To pass a single dynamic parameter, specify the parameter's name using the paramId
attribute. You can then specify the name of the JavaBean holding the value using the
paramName attribute, and a particular property using paramProperty.
So, a tag like
<html:link paramID="target"
paramName="linkParams"
paramProperty="target"
paramScope="request"
>detail.html</html:link>
this is from
http://jakarta.apache.org/struts/api-1.0/org/apache/struts/taglib/html/package-summary.html#doc.Other.hyperlinking
in this way you can add one parameter to the querystring. there is also
a way to add more than one parm...
hope this helps
Alexander

Subject: rtexprvalue not working in <html:link> tag!!! --- REVISITED
OK, this is weird. The <html:link> page attribute doesn't work as expected
when you append a query string to a scriptlet, as in <html:link page="
<%=somepage%>?color=green" >. Here sample code that highlights the
discrepancy. Can someone explain??
------------------------------------------------- SCENARIO ONE - no
queryString - this works Yay!
--------------------------------------------------------------------------
**************JSP PAGE:**************
<% String somepage= "/crazylink.do"; %>
<html:link page="<%=somepage%>" >click</html:link>
**************JAVA CREATED FROM JSP:**************
String somepage = "crazylink.do";
org.apache.struts.taglib.html.LinkTag _jspx_th_html_link_0 = new
org.apache.struts.taglib.html.LinkTag();
.... code ....
_jspx_th_html_link_0.setPage(somepage);
************** LINK CREATED ****************
http://localhost:8080/myapp/crazylink.do
--------------------------------------- SCENARIO TWO - using a queryString
- this does NOT WORK. BOO!
------------------------------------------------
**************JSP PAGE:**************
<% String somepage= "/crazylink.do"; %>
<html:link page="<%=somepage%>?color=green" >click</html:link>
**************JAVA CREATED FROM JSP:**************
String somepage = "crazylink.do";
org.apache.struts.taglib.html.LinkTag _jspx_th_html_link_0 = new
org.apache.struts.taglib.html.LinkTag();
.... code ....
_jspx_th_html_link_0.setPage("<%=somepage%>?color=green");
************** LINK CREATED ****************
http://localhost:8080/myapp/<%=somepage%>?color=green
***Note: I realize one can just append the query string like so:
<% String somepage= "/crazylink.do?color=green"; %>
But this does me no good since the link "/crazy.do" will be used throughout
the page with different queryStrings for each.

<html:link> tag!!!
PM
Please respond to
struts-user
Anyone know why my scriptlet in the following <html:link> tag is not being
evaluated?
******************************************************************************
<%
String somepage= "index.jsp";
%>
<html:link page="<%=somepage%>">Click Here</html:link>
******************************************************************************
The value showing up is not the evaluted scriptlet, but the scriptlet
itself, as in "http://localhost:8080/myapp/<%=somepage%>"
I'm using Tomcat4.0 & Struts1.0
Scriptlets are evaluated in other custom tags I have used so I don't think
it's a jasper issue... I don't htink it has to do w/ the taglib either...
What's up???
Thanks,
-Craig
To be sure, the page attribute accepts a rtexprvalue:
<attribute>
<name>page</name>
<required>false</required>
<rtexprvalue>true</rtexprvalue>
</attribute>
