AW: Tomcat -- IBM WebSphere Application Server 4.x
Thanks for your replay!
But that was not exactly what I was looking for ;)
Maybe my description wasn't clear enough!
So I'll try again:
1. I can create a WAR file using ANT (see Appendix: ANT)
2. I can deploy it in Tomcat
3. I can not deploy it in WebSphere!
Error message: missing DTD ~ deployment descriptor
Although I defined my web.xml correct (I think - see Appendix:
web.xml)
I searched the IBM website for a document which describes the process of
migrating a tomcat app 2 WebSphere, but I could not find any.
Again:
Has anyone done that before?
Or/And has anyone a HowTo which explains the process?
Thanks
Oliver

Out of the box, WAS wants an EAR file (Enterprise Application aRchive)
and
not a WAR file. You could create a new 'default' EAR project and add the
web
project to that ear. Then deolpy the EAR on WAS. Unfortunately, this
sounds
simplerer than it really is. Are you deploying on WAS from WSAD or do
you
use a standalone WAS server. The Admin tool should help you in the
latter
case.
I have heard people deploying WAR directly on WAD, but I don't know this
myself. Perhaps the IBM website can help you out.

Hi all,
I use the StrutsStudio (based on eclipse) to develop my Struts app.
The StrutsStudio uses Ant to build the WAR file. If I deploy my app
in Tomcat anything works fine, but I am not able to use my WAR file
within the WAServer from IBM. There I always get a massage that
this is not an enterprise WAR file ... ?!
Has anyone done that befor and can guide me with that?
Does any know a good how to or resource on the net?

I check if session expires for each action in the
application. If the session times out, I forward the
user to index.jsp so that the user can log on again.
How do I inform the user with a message that he/she is

If you are implementing connectionpool, the overhead is the time to return the connection to the pool and get it back. The iBATIS DAO splits the difference and makes transaction management part of the logical DAO API. So you can specify different connection mechanisms at instantiation, and the implementating code does not need to know the details. The DAO implementation can just call high-level methods like startTransaction, commitTransaction, or rollbackTrnasction. This strategy limits what the implementaton needs to know about the connection management, but still lets the business logic determine what constitutes a transaction (which is often a business decision). -Ted. -- Ted Husted, Junit in Action - http://www.manning.com/massol/, Struts in Action - http://husted.com/struts/book.html, JSP Site Design - http://www.amazon.com/exec/obidos/ISBN=1861005512. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] The information in this message is confidential and may be legally privileged.

Re: Keeping Actions clean - separating actions from business mode l from persistence
Allow maybe have a couple of generic actions that can save/retrieve and list these objects instead of having to write a action for each form. ie : instead of have to write a form bean/jsp page/edit action/search action/delete action etc.. you just create the xml sql object with some extra details like the search field/edit fields etc. and in you pageflows link the object to the correct type of action like edit/add/search and as these are standard action you do not need to code them?

Should the business Logic do connectionManagement (e.g. opening a connection (via a connection pool or otherwise)) or should that be the responsibility of the persistence layer. Doing it in the latter(PersistenceLayer) frees up the BusinessLayer of connection Mgt code. If you are implementing connectionpool, the overhead is the time to return the connection to the pool and get it back. The iBATIS DAO splits the difference and makes transaction management part of the logical DAO API. So you can specify different connection mechanisms at instantiation, and the implementating code does not need to know the details. The DAO implementation can just call high-level methods like startTransaction, commitTransaction, or rollbackTrnasction. This strategy limits what the implementaton needs to know about the connection management, but still lets the business logic determine what constitutes a transaction (which is often a business decision). -Ted. -- Ted Husted, Junit in Action - http://www.manning.com/massol/, Struts in Action - http://husted.com/struts/book.html, JSP Site Design - http://www.amazon.com/exec/obidos/ISBN=1861005512. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] The information in this message is confidential and may be legally privileged.

xml objects for forms and persistence
I will be working on porting a company framework (and hopefully open source it) from ASP/VB (yack!) to Java. The idea of the framework is quite simple. It is a framework for buiding administration screens like update/search edit user but it has some interesting features : The Business objects a described in xml ie : entity nameuser/name tableusr/table attributes namefirstname/name label EN labelFirst Name/label /EN . /attributes attributegroups attributegroup nameLabel/name attributes attributefirstname/attribute attributesurname/attribute /attributes /attributegroup attributegroup nameEdit/name attributes attributefirstname/attribute attributesurname/attribute /attributes /attributegroup etc.. /entity The Business Object xml descriptor has enough information for display it as well as updating it. AttributesGroups allow for list views and edit views of the object. Another component of the framework is the PageFlows that are made up of Actions that use these Business Objects to get the info for these views like Edit User. Most of the time you do not need to write code at all, we have also written a editor for the Business Objects and the Pages Flows. So at the end of the day the html of genernated by the framework from the xml descriptor and the persistence is also done from there. So doing administration screens are very quick. ie : days instead of weeks. The some code can be used for web front ends as well as guis. I was wondering it there is anything else out there like this or are there ways on doing some intergration of this with Struta and Hibernate and Cocoon? At the end the benefits are amazing taking minutes rather than hours to get stuff done I really mean radically, to do a search/edit/delete etc.. for a object takes minutes. And being frontend independent means that you can write web as well as swing stuff. Mike The information in this message is confidential and may be legally privileged.
