RE: Quick Iterate Question - DefaultTableModel
I've just tried using a DefaultTableModel and succeeded nesting the iterate
tag.
JSP is as follows:
<%-- Generate table data by nesting the iterate tag --%>
The property 'model' is a DefaultTableModel in my ActionForm
'jobMonitorForm' with getter as follows
public DefaultTableModel getModel()
{
return model;
}

Subject: Quick Iterate Question - DefaultTableModel
Here's a quick one - anyone use or modify iterate to support iterations
through a DefaultTableModel. Since it's just a vector of vectors we tried
nesting iterate tags, but to no avail. Anyone already done this or do I need
to code it myself if I want it (hehe)? :)

RE: How do you use indexed properties with html:input?
Turgay,
I've just tried that but get the following exception:
javax.servlet.jsp.JspException: Cannot find bean contributorEditForm in
scope session
I've removed all useBean tags from my jsp and have added the following in my
action class:
ContributorEditForm contributorEditForm =
(ContributorEditForm)session.getAttribute( "contributorEditForm" );
if ( contributorEditForm == null )
{
contributorEditForm = new ContributorEditForm();
session.setAttribute("contributorEditForm", contributorEditForm );
}
My JSP contains code like:
Have I done something wrong?
As for debugging, I haven't really been able to so far, I've just been
putting System.out's in my Action class. I'm about to install JBuilder
Enterprise (I normally use the Foundation version ) as this supports JSP
debugging, so I'll let you know if it's any good.

Subject: RE: How do you use indexed properties with html:input?
Richard,
I put my bean in session scope when I create it in an action class:
OracleConnBean dbconn=null;
dbconn = (OracleConnBean)session.getAttribute("dbconnection");
if(dbconn == null) {
dbconn = new OracleConnBean();
session.setAttribute("dbconnection", dbconn);
}
Then, I can access the object from my jsp pages without using jsp:useBean.
I am not exactly sure because I am not very much experienced with
jsp/servlets, but this may be the reason for those 3 beans created. By the
way, how did you find that out? How do you debug? (This may be a more
general question as what is the best way to debug jsp/servlets? I don't
debug yet, but I want to. I am using Forte CE. I heard about debugging in
Tomcat using IBM VAJ, do I need to get that?)
When you don't use jsp:useBean, you better use the "type" attribute in your
iterate tag, to get the correct object type:
HTH,

Hi,
I made the following changes in my Action class and got my save to work.
HttpSession session = request.getSession();
TestGridForm testGridForm = (TestGridForm)session.getAttribute(
"testGridForm" );
However, while trying to debug my problem I found I get 3 ActionForm Beans
created when I only expected 1.
In my jsp I have the following:
I have added scope="session to the logic:iterate tag e.g.
On the page where I display the results I also have:
I expected all the above to refer to the session scoped bean "testGridForm",
so why are 3 beans created?

Subject: RE: How do you use indexed properties with html:input?
Turgay,
Thanks for your help, I've tried something similar to your example, but I'm
still having some trouble. I've probably missed something obvious as I'm
new to struts & JSP.
In my jsp I've got the following:
<%@ page import="com.qspgroup.utc.TestGridForm" errorPage="fcerror.jsp" %>
<%@ taglib uri="/WEB-INF/utctags/fcutc.tld" prefix="fcutc" %>
<%@ taglib uri="/WEB-INF/lib/struts/struts-bean.tld" prefix="struts_bean" %>
<%@ taglib uri="/WEB-INF/lib/struts/struts-html.tld" prefix="struts_html" %>
<%@ taglib uri="/WEB-INF/lib/struts/struts-logic.tld" prefix="struts_logic"
%>
<% int i=0; %>
" size="10"
value="">
<% i++; %>
My action class is as follows:
public ActionForward perform( ActionMapping mapping, ActionForm form,
HttpServletRequest request,
HttpServletResponse response ) throws
IOException, ServletException
{
if ( form == null )
{
form = new TestGridForm();
}
TestGridForm testGridForm = ( TestGridForm )form;
for ( int i = 0; i < testGridForm.getData().length; i++ )
{
if ( request.getParameter( "data" + i ) != null )
{
testGridForm.setData( i, request.getParameter( "data" + i )
);
}
}
return ( mapping.findForward( "success" ));
}
As you can see It doesn't do a lot. My ActionForm class creates dummy data
and contains and contains get/set methods as shown below:
public class TestGridForm extends ActionForm
{
String[] data = { "Rail", "Fridges", "Hay", "1", "2", "3", "4", "5",
"6", "7", "8", "9", "10", "11", "12", "13" };
public String[] getData()
{
return data;
}
public String getData( int i )
{
return data[i];
}
public void setData( String[] data )
{
this.data = data;
}
public void setData( int i, String d )
{
data[i] = d;
}
My data gets displayed OK. On success I go to testgrid.jsp but this keeps
displaying the original data. I've checked the tomcat log files and the new
data is being sent as request parameter so I don't understand why the new
data isn't saved in my bean.
e.g. 2001-05-10 09:21:20 -Request Params:
2001-05-10 09:21:20 -data2 = 30
2001-05-10 09:21:20 -data1 = 20
TestGrid.jsp is as follows:
<%@ page import="com.qspgroup.utc.DataCaptureDemo" errorPage="fcerror.jsp"
%>
Test JSP
Test JSP Page
<%
out.println( "data in 1st cell is "+ testGridForm.getData( 0 )
);
out.println( "data in 2st cell is "+ testGridForm.getData( 1 )
);
out.println( "data in 3rd cell is "+ testGridForm.getData( 2 )
);
%>
Sorry to swamp you with info, I can't seem to figure this out, although I'm
sure I've missed something obvious here.
Thanks.
Richard.

the struts tags if possible

out.println( "" );
}
else if ( element.equals( "false" ) )

If anyone knows how to do this using the struts logic tags then let me know.
