Struts & XML
Currently I'm calling a database subroutine (in an Action) that returns a
list of keys, and then using a DAO in a loop to build up a List of Java
objects that contain the data I need to display. That List gets put in
session scope and then it's off to the resolution.jsp to display it with a
<logic:iterate> tag.
*IF* I changed the database subroutine to return XML, what would I do with
it? I'd have something like this coming back:
<content>
<person>
<name>John Smith</name>
<birthdate>05/25/1965</birthdate>
<status>PP</status>
<address>
123 State Street
City, ST, 12345
</address>
<source>ALUM</source>
<reunion_class>ML1999</reunion_class>
<reunion_class>ME2002</reunion_class>
</person
</content>
(I'm unclear on how to format the address which has multiple lines.)
Anyway, would I put that String in session scope? And then... I'm just
reading about XSLT now. Can someone point me in the general direction of
which Struts (or other) taglibs I might need? I'm on Tomcat 4.1.12 & a
recent Struts nightly build with the -el tags.
Thanks in advance,

JSTL (in jakarta tag libs) X:transform tag will take a XML and XSLT it.

Indexed form Properties
Posted by "Virgilio Lustre Jr." <co...@yellowasp.com>.
Hello People,
I am quite new to struts. and right now i am using 1.1. I have questions
regarding creating indexed form elements...
I want to be able to have multiple updateable objects.
my jsp page...
<html:form action="/stockControlConfirm.do" method="POST">
<logic:iterate id="stock" name="stockSearch" scope="session"
offset="<%= pager.getOffset() %>" length="<%=
pager.getLength() %>" type="com.yellowasp.isolaconsign.Stock">
<html:text property="batch" size="8" maxlength="20" indexed="true"/>
<html:hidden property="id" size="8" maxlength="20" indexed="true"/>
</logic:iterate>
</html:form>
My questio0ns are:
1. How do I create the form beans with indexed type properties? Do I have to
create indexed field/getters/setters on my form bean?
2. How do i catch it with my action class?
Illustrations:
public ActionForward perform(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {}
Is the Action form in this template enough? or is there another variation
with the perform method?
tnx.

I made use of Digester the first time yesterday.
I was amazed at how easy and convienient it is to use - only took an hour to
learn enough to use it for what I wanted. (Reading some config data and
creating objects from it)
Very cool :-)
I Like!

Of course, the suggestions to check out STXX or the JSTL to use XSLT
to style your XML are perfectly good... and maybe that's why you
decided to change your subroutine to return XML... but if you want
to get things back into familiar object-land, you could pass the XML
to some routine which could produce a java Object for you from the
XML. Then you could use the object in Struts in all the usual ways.
There are whole frameworks for this (Betwixt, Zeus, Castor, others)
but if you only need to consume the XML and never need to write it
out in the same fashion from the object, you might want to check out
Jakarta Commons Digester (which is how Struts reads in all of its
configuration files.)
Once I learned how to use Digester, I never again had a moment's
pause over the question of whether it was "too much trouble" to use
an XML file to externalize some data -- it's really easy to use,
especially if you have the liberty of designing your own XML format,
in which case you can make things even easier. Basically, you can
assign an element name to an object and use attributes of that
element named exactly as the properties of that object, and you can
get Digester to construct and populate a bean for you in about three
lines of code.
See http://jakarta.apache.org/commons/digester/api/ for details;
there isn't a lot more documentation, but the Javadoc is pretty
complete.
One thing to note is that digesters aren't designed to be threadsafe;
if you are using digester in a servlet environment, you should keep
in mind the same considerations as when writing servlets.

Re: Struts & XML
Posted by Joe Germuska <Jo...@Germuska.com>.
Of course, the suggestions to check out STXX or the JSTL to use XSLT
to style your XML are perfectly good... and maybe that's why you
decided to change your subroutine to return XML... but if you want
to get things back into familiar object-land, you could pass the XML
to some routine which could produce a java Object for you from the
XML. Then you could use the object in Struts in all the usual ways.
There are whole frameworks for this (Betwixt, Zeus, Castor, others)
but if you only need to consume the XML and never need to write it
out in the same fashion from the object, you might want to check out
Jakarta Commons Digester (which is how Struts reads in all of its
configuration files.)
Once I learned how to use Digester, I never again had a moment's
pause over the question of whether it was "too much trouble" to use
an XML file to externalize some data -- it's really easy to use,
especially if you have the liberty of designing your own XML format,
in which case you can make things even easier. Basically, you can
assign an element name to an object and use attributes of that
element named exactly as the properties of that object, and you can
get Digester to construct and populate a bean for you in about three
lines of code.
See http://jakarta.apache.org/commons/digester/api/ for details;
there isn't a lot more documentation, but the Javadoc is pretty
complete.
One thing to note is that digesters aren't designed to be threadsafe;
if you are using digester in a servlet environment, you should keep
in mind the same considerations as when writing servlets.
