Hi,
I use JSTL sql tag library to generate a result set (flst) based on the
following
SQL query:
select group_name from user_groups as c where c.login_id like 'xxx' order by
c.group_name
I use the following displaytag table to display result.
<display:table name="${flst.rows}" pagesize="25" defaultsort="1"
defaultorder="ascending" export="true">
<display:column property="group_name" title="Group Name"
sortable="true"/>
</display:table>
I'd like to add one more column after group_name that displays a HTML link based
on the group_name. I changed the table code into:
<display:table name="${flst.rows}" pagesize="25" defaultsort="1"
defaultorder="ascending" export="true"
decorator="org.displaytag.customize.Wrapper">
<display:column property="group_name" title="Group Name"
sortable="true"/>
<display:column property="groupFiles" title="Group Name" />
</display:table>
Below is the code I wrote for the wrapper.java program.
package org.displaytag.customize;
import org.displaytag.decorator.TableDecorator;
public class Wrapper
extends TableDecorator
{
public String group_name;
public String getGroupFiles()
{
Wrapper object = (Wrapper)getCurrentRowObject();
String groupName = object.getGroup_name();
return "<a href=\cfor.jsp?groupName=" + groupName +"\>Files
Owned</a>";
}
public String getGroup_name ()
{
return group_name;
}
public void setGroup_name (String value)
{
group_name = value;
}
}
I am getting the following errors:
javax.servlet.ServletException: Error looking up property "groupFiles" in object
type "org.displaytag.customize.Wrapper".
org.apache.jasper.runtime.PageContextImpl.doHandlePageException(PageContextImpl
.java:848)

org.apache.jasper.servlet.JspServlet.service(JspServlet.java:241)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
Obviously, I am kind of new to the Java and displaytag library. Can anyone here
point out what I did wrong?
Thanks,
