multiple rows of editable data
Hi,
I have a master detail form where the detail section has multiple rows
which have one field to be updated per row. There is one submit button
at the end of the form which will allow the data in the form to be
updated in to the data store. How do I make the field represent a
unique number, putting the detail row id?
Thanks
Amin
Re: Log4J and Struts
Posted by Mahesh Joshi <jo...@comcast.net>.
Hi,
Unfortunately this does not work for Tomcat 4.1.24
When I put log4j-1.2.8 in the jak*/common/lib or jak*/shared/lib I dont get
the results desired.
In the former, tomcat doesnt startup and in the latter struts does not
initialize.
Looks like I am missing something in the relationship between
commons-logging and Log4J.
Thanks!
Mahesh

Hi,
I am moving my current web application to struts and I am facing a problem.
We use Log4J for our logging (Log4J version 1.2.8)
If I have the log4j-1.2.8.jar in my WEB-INF/lib directory, the Action
servlet does not initialize
Tomcat log file says:
javax.servlet.ServletException: Error instantiating servlet class

If I remove the log4J.jar from WEB-INF/lib, the ActionServlet
initializes(but then my app. cant log).
I searched the archive and implemented the solution provided by Sgarlata
Matt
http://www.mail-archive.com/struts-user@jakarta.apache.org/msg79448.html
Howeve, putting the commons-logging.properties in the WEB-INF/classes/
folder didnt help either.
(note that our log4J config file has been kept in the WEB-INF folder. Even
if I keep the commons-logging.properties in the WEB-INF folder, it doesnt
work).
Please help!

Re: multiple rows of editable data
Posted by Abhijeet Mahalkar <Ab...@indussoft.com>.
Yes If you are having ur data in the Xml then generate one tag srlNo aong with other tags and add this tag for each row and id of each tag in the row has to be the same as well as it has to be row id. Then u can retireve this activelement.getAttribute("id") ; and get the TR of the table depends on this "id" value then retrieve cell value of this row.. this way you can retireve the values as well as you can maintain uniqeness in each row of the table..
if you do not understand pls tell me i will forward a sample code for you..
