Struts Search/Results/Display Help (includes link to Example to help me with)
http:// www ! moosejaw ! org /java/help.zip
Here is a zip file to demonstrate the problem I am having. I just hacked
this together, but it shows what I have been talking about.
1. Unzip this and put the helpv1.war in your webapps folder
2. Start servlet container
3. Goto http://localhost:8888/helpv1
This should take you to index.do which is fine. Click "Search" which takes
you top search.do. Type "1" for the Item Id and select "Lable 2" for the
Utem Type and click "Search". Do you see how the values are lost? How can
I mantain those values? Should I just have 1 Action class that handles both
the search form and the search results? If so, how do I set this up?
Thanks for your help!
Matt

For your steps 2 to 4:
in your struts-config:
<form-bean name="myForm" type="com.my.form.MyForm"/>
...
<action path="/pageWithForm" type="com.my.action.PreparePageAction">
<forward name="showForm" path="/form.jsp">
</action>
<action path="/formDestination"
type="com.my.action.PreparePageAction"
name="myForm"
input="/form.jsp">
... <!-- show page for step 4 -->
</action>
in your jsp:
<html:form action="/formDestination">
<html:text property="someMyFormProperty"/>
<html:text property="otherMyFormProperty"/>
<html:submit/>
</html:form>
<%-- also use the struts tags to display error messages --%>
In your case, you may need to use input="/pageWithForm.do" since you need to
prep
the form, but there are other ways to do that, like placing your <SELECT>'s
options collection in session or app scope. However, I *have* used this
approach
before and it worked for me.

Re: JSP to static html...
Posted by Jacob Wilson <st...@yahoo.com>.
Actually, this is therequirement... One jsp page(contains scriptlets, dynamic values. etal) in the current application generates a report. Now, I need to present with a button at the end of the page.
When I click on that button, this page should be converted into a static html and then
ftp this html page to one of the servers...
I know uploading could be done without probs... But, the only question I have is how do I convert that page into an html???

RE: JSP to static html...
Posted by Wiebe de Jong <wi...@shaw.ca>.
David,
I have had this situation come up before and it is quite valid.
I once wrote a catalog web app for a client with only a couple of templates
but hundreds of items in the database. They wanted a static cdrom version of
the catalog for customers so I used a tool (can't remember the name now but
it started with an 'x') to spider through the site, make an html copy of all
the pages, and fix the links appropriately.
The only tools I can think of now are:
Zylox: http://www.zylox.com/tasks/dynamic2static.shtm
Teleport Pro: http://www.tenmax.com/teleport/pro/home.htm

Re: JSP to static html...
Posted by Max Cooper <ma...@maxcooper.com>.
Jacob,
It sounds like your requirements preclude doing this at build time. I assume
having the button to ftp a static HTML version of the report to a server
somewhere means that the report has some parameters to customize the report,
or at least that the report should be run at the time the user clicks the
button (even if there is no configuration of the report itself).
In that case, it seems like you could have the server make a request to
itself and then save the response (HTML generated by executing the JSP) in a
file or just stream it directly to the ftp server that is waiting to receive
it. I don't have any magic tips about converting JSP to HTML -- I would just
let the server execute the JSP to convert it to HTML. If you need to strip
things out (JavaScript, etc.) you may need to create a new JSP or manipulate
the response to remove that stuff.

RE: Struts Search/Results/Display Help (includes link to Example to help me with)
Posted by "Matthew J. Vincent" <vi...@cs.usm.maine.edu>.
Hubert...thanks!
Now, how do I then clear the fields out if the want to do a new search?
Currently, the user types in http://localhost:8888/helpv1/search.do , the
values that they filled in are still there. I only want those values to
"persist" if there is an error of some sort...otherwise reset back to
original. Another way to think of it is when the user links to the search
page it should be "fresh", but on error it is "dirty". I tried changing the
scope to session, but that didn't help. Is there a trick to the reset
method in the form that I should use?
Matt

Like in my two previous emails, it worked when I took out the "name" and
"type"
attributes in your html form:
<%--
<html-el:form action="searchResults"
name="itemSearch"
type="SearchForm">
--%>
<html-el:form action="searchResults">
