Thanks so much!  Can you tell me where I can get the org.displaytag.sample files?  I only had the code for the wrapper because someone posted it on a help forum I had read.  I really appreciate your help.  I find the displaytag website documentation completely useless.  The code that I do have working (to display the table) is nothing like their examples - I can't get anything from their examples to work - I always have to get online help from users to get anywhere.  

I am using Resin instead of tomcat (my hosting company provides that).

I currently have the following jar files in my WEB-INF/lib directory:

commons-beanutils-bean-collections.jar
commons-beanutils.jar
commons-collections-3.2.jar
commons-lang-2.2.jar
commons-logging-1.1.jar
displaytag-1.1.jar
displaytag-export-poi-1.1.jsr
itext-1.4.jar

I tried adding import org.displaytag.sample.*;
to my Wrapper.java class, but I get the following error message:

500 Servlet Exception

Note: sun.tools.javac.Main has been deprecated.
/home/teska/public_html/sandbox1/WEB-INF/classes/teska/displaytag/Wrapper.java:22:

Resin 2.1.16 (built Tue Feb 15 11:12:27 PST 2005)

I'm assuming this is because I don't have the right jar loaded in my WEb-INF/lib directory.  Ideally I could copy the files into my own package so I can modify them if needed - like I did to the Wrapper.java class.  

Also, do you know if there is any documentation on the classes in the sample package?  I haven't even seen where I can get the package let alone what is in it.

Thanks,

Thanks - I've finally found the sample code.

I took a look at the ListObject class that was re fenced in the dynamic link table decorator example, but it appears I misunderstood the example.  I thought the ListObject was a class that pulled in data from my displaytag table - I guess from the documentation it just randomly genereates data to put into a link - not very helpful.  

Do you know if there is any way within my Wrapper function to access the sfdid value row by row from my displaytag table based on my RowSetDynaClass called new_ncs?  The sfdid value is the first value in my RowSetDynaClass.  What I was hoping to do was access that value and then use it to query my database to get yet another value and append the sfdid and the new value to the link in my table.  I've tried posting 2 questions like this to the displaytag forum and one other question here, but no one seems to have any idea how to do this - I never get any answers from anyone on the displaytag forum - really frustrating!

Thanks,
Courtenay

I've been doing more searching on the displaytag forums to try and figure out what I'm supposed to be doing.  I've modified my Wrapper Class, but I'm still having problems.  Here is my latest code:

JSP Code:

<%
                                RowSetDynaClass new_ncs = ActionViewTables.newNCTableSC(sdid_string);
                             
%>      
                                <% request.setAttribute("new_ncs_sc", new_ncs); %>

                                <display:table name="requestScope.new_ncs_sc.rows" id="row" decorator="teska.displaytag.Wrapper">
                                    <display:column property="sfdid" title="ID" sortable="true"/>
                                    <display:column property="level" title="Level" sortable="true"/>
                                    <display:column property="form_name" title="Form Name" sortable="true"/>
                                    <display:column property="last_name" title="System Coordinator" sortable="true"/>
                                    <display:column property="date_submitted" title="Date Submitted" sortable="true" decorator="teska.displaytag.LongDateWrapper"/>                                                                      
                                    <display:column property="scNcViewLink" title="View" />                                    
                                </display:table>

According to the error message it appears the error is in the nc_lists.jsp code, but if I use the following code in the jsp (removing references to the Wrapper class), the table displays with no problem:

<%
                                RowSetDynaClass new_ncs = ActionViewTables.newNCTableSC(sdid_string);
                             
%>      
                                <% request.setAttribute("new_ncs_sc", new_ncs); %>

                                <display:table name="requestScope.new_ncs_sc.rows" id="row">
                                    <display:column property="sfdid" title="ID" sortable="true"/>
                                    <display:column property="level" title="Level" sortable="true"/>
                                    <display:column property="form_name" title="Form Name" sortable="true"/>
                                    <display:column property="last_name" title="System Coordinator" sortable="true"/>
                                    <display:column property="date_submitted" title="Date Submitted" sortable="true" decorator="teska.displaytag.LongDateWrapper"/>                                                                      
                                                                     
                                </display:table>

Hi,

Thanks for the ideas. I tried changing the sfdid get and set methods to int instead of String.  The level and last_name and form_name are var_chars in my database (which pull out as Strings normally) and date_submitted is a timestamp with time zone.   I assume date_submitted is still a String, at least I've pulled it into the database that way in the past.  Unfortunately I still received the same error message as I did previously.  


 Here is my code for LongDateWrapper:
