I'm new to struts, I'm trying to use the iterate tag with to retrieve data
from a db and display it. We have the functionality working with our java
classes and now I'm trying to incorporate it using struts. The following
code illustrates how we are doing it now.
<%
try {
sai.db.IRecordIterator it =
invoiceService.getStatusSummary();
while (it.next()!=null) {
aig.its.db.RecordInvoice rec =
(aig.its.db.RecordInvoice) it.current();
%>
<td class="ft"><%=rec.getGroupCount ()%></td>
<td class="ft">$<%=rec.getGroupSum
(aig.its.db.Tables.Invoice.InvoiceTotal).setScale(2,java.math.BigDecimal.ROU
ND_DOWN)%></td>
</tr><%
if (currentSwapColor==0) currentSwapColor=1; else
currentSwapColor=0;
}
}
catch (java.sql.SQLException E) {
%><%=E.toString()%><%
}
%>.
Now I'm trying to convert the above iteration using the iterate tag of
struts, what I've done is this
<%
try {
sai.db.IRecordIterator it =
invoiceService.getStatusSummary();
pageContext.setAttribute("it", it, PageContext.PAGE_SCOPE);
while (it.next()!=null) {
aig.its.db.RecordInvoice rec =
(aig.its.db.RecordInvoice) it.current();
pageContext.setAttribute("rec", rec,
PageContext.PAGE_SCOPE);
%>
<logic:iterate id="item" name="it" property="rec">
<tr bgcolor="<%=swapColor[currentSwapColor]%>">
<td align="left">
<bean:write name="rec" property="getGroupCount ()" filter="true"/>
</td>
<td align="left">
<bean:write name="rec" property="getGroupSum
(aig.its.db.Tables.Invoice.InvoiceTotal)" filter="true"/>
</td>
</tr>
</logic:iterate>
<%
if (currentSwapColor==0) currentSwapColor=1; else
currentSwapColor=0;
}
}
catch (java.sql.SQLException E) {
%><%=E.toString()%><%
}
%>
.
I'm getting the exception
javax.servlet.ServletException: No getter method for property rec of
bean it.
I have no idea where I'm going wrong, but I would appreciate if you could
help me sort this problem out.
Another problem that I'm facing is to convert the following to a struts
equivalent command, here I guess the jsp is called based on the multiple
params passed to it, I couldn't find anything similar in struts. Please
help.
<td class="ft"><a
href="invoice/list.jsp?numFields=1&wo0=eq&wf0=InvoiceStatus&wv0=<%=rec.getIn
voiceStatus()%>"><%=rec.getInvoiceStatusDescription ()%></a></td>

The Struts tags often throw exceptions, but I don't believe any write to
a log. They do record the Exception in the request context though, so it
can be reported elsewhere (e.g. an JSP error page). Here's an example
from interate:
else {
JspException e = new JspException
(messages.getMessage("iterate.iterator"));
RequestUtils.saveException(pageContext, e);
throw e;
}
The messages for the exceptions are in <
taglib\logic\LocalStrings.properties >.
Sorry I could help with committing the indexed tag, but I haven't had a
chance to use it myself.
