james,
thanks for your response.
do you know if your tag lib works w/ Weblogic? if i get a
NullPointerException error does this mean i have a problem w/ my syntax or
am i not configuring the tag on the server correctly?
i basically copied the Jar file to my "lib" directory that's in my startup
path. what else do i need to do? (sorry for such a basic question but this
is the first time for me to try a custom tag outside of what this group is
already using and i'm new to weblogic sever config issues.)
here's my syntax so far:
***********************************************************************
<%@ taglib uri="lib/pager-taglib-1.0.jar" prefix="pg" %>
...other import stuff
<!-- es: prepare sql and process -->
<es:preparedstatement id="ps" sql="<%=sSQL%>" pool="portal">
<%
//query: execute
java.sql.ResultSet rs = ps.executeQuery();
//query: get column count
ResultSetMetaData metadata = rs.getMetaData();
int cols = metadata.getColumnCount();
int row = 1;
%>
...other query stuff
<%
//pager tag: build table index
%>
<table border="1" width="90%">
<!-- pager tag: prepare page table -->
<pg:pager >
<!-- pager index tag: -->
<pg:index>
<!-- html: tags -->
<center>
<table>
<tr align=center valign=top>
<td valign=top>
Result Page:
</td>
<!-- pager prev tag: -->
<pg:prev ifnull="true">
<% if (pageUrl!=null){%>
<td> <a
href="<%=pageUrl%>">Previous</a></td>
<%}else{%>
<td>Previous</td>
<%}%>
</pg:prev><!-- end pager prev tag
-->
</tr>
</table>
</center>
....other pager tag stuff
</pg:index><!-- end pager index tag -->
</pg:pager><!-- end pager tag -->
<%
...other jsp stuff
%>
</es:preparedstatement>

I've used it. :-)
By looping data source I mean any loop construct (JSP Tag or Java based)
that can be used to generate data. In the examples, the tag
<ex:searchresults></ex:searchresults> would evaluate the body content
of the tag for each search result that it contains.
The loop can also be any Java loop construct (for, while, do). The
following
is the loop code for the pager demo.
<table width="90%" cellspacing="4" cellpadding="4">
<% for (int i = 0; i < webPalette.length; i++) { %>
<pg:item>
<tr><th bgcolor="<%= webPalette[i][0] %>"><font color="<%=
webPalette[i][1] %>">
<%= i + 1 %></font></th></tr>
</pg:item>
<% } %>
</table>
Here is very simple loop:
<% for (int i = 0; i < 100; i++) { %>
<pg:item><%= i %></pg:item>
<% } %>
Also, David's explanation is exactly right.
