Re: Unit testing a struts application
Cactus works great with Struts. Just go to there web page http://jakarta.apache.org/cactus/index.html and check out the documentation examples. Join their user list, check the archives and if you still have questions ask the Cactus user group. You will also need to know all about JUnit - http://junit.org/index.htm Jim From: Daniel H.

One of greatest things i've found is XP. I liked it very much. One of XP rules is about unit testing. So follows my question : How can i unit test a struts app? I heard about Cactus (another Jakarta project). Does someone here have experience using it? All kind of use cases would be a plus. Best regards, Daniel. __ Do you Yahoo!?

Re: Distinct case in validate() with a form used in several page
Couldn't you create your actionFormBean and then create sub-classes for each different type of validation? Might give you a cleaner solution. Jim From: Vincent Berruchon [EMAIL PROTECTED] Reply-To: Struts Users Mailing List [EMAIL PROTECTED] To: Struts Users Mailing List [EMAIL PROTECTED] Subject: Distinct case in validate() with a form used in several page Date: Thu, 26 Sep 2002 16:35:06 +0200 I'd like to use an actionFormBean with a few JSP form page. But I'll have to treat different cases in the validate of my actionFormBean... So in validate(), I was thinking about looking at the name of the input JSP with ActionMapping.getInput() ( or perhaps the name of the current action to choose the right case, /w getType() ). Is it an acceptable way to do that? I coulds also use an property of the formBean perhaps...

RE: Struts and high performance sites
We have a couple Struts applications in production. Using Struts as the front end, all transaction go through a Delegator level (session control) to stateless session EJBs, then passed to transaction processors and finally to different legacy backend systems. Before we could go into production we needed to stress test from the Delegator back to the legacy systems against the old C++ application. Using JUnit and JUnitPerf we simulated 286 concurrent users, 45 transactions a second for 15 minutes. The averages where; Delegator 48 milliseconds, EJBs 1 millisecond and transaction processor 54 milliseconds. This blew away the old C++ application. EJBs are definitely not a performance problem. Back to the original question, all though we have a lot less concurrent users then you will have, performance using Struts has not been an issue at all. The Struts front-end is a lot faster then the old home grown one and was easier faster to develop. We are now in the process of developing our 3rd and 4th Struts applications. These will even be faster to develop because we are basically just creating new JSPs (different brands) and reusing 80%-90% of the existing data forms actions.

Should fit on a single medium box (if not a laptop) if you do it right. You have to worry about creating objects if you write your own framework (you can put beans in session or requests, and request is better mostly), and then you have 2 projects, your app and a framework, and you won't do better than the Struts team and what about framework bugs? Also, with Struts, my clients are able to write several modules(pages) per day per developers, how's that for productivity or beating the schedule? Some of the Struts sites are 50 times more concurrent users I have worked on, no problem. The slow part is DAO in J2EE (and ADO in .NET). Avoid any EJB, they do not scale. Some good choices is RowSet(I do metadata w/ reflection to auto gen SQL updates - RowSet also avoids BO/DTO/VO mapping and GC), Resin, pgSQL, Eclipse or CodeGuide IDE, Linux/KDE and J:Rockit VM or IBM VM (Sun VM and Sun Inc. have issues).

We are going to use J2EE as the ground platform. I am now considering some design choices where using Struts is one of them. However I have some questions regarding the performance of Struts. I know this issue has been up many times before but I have never been able to find any satisfying answers, so... What, if any, overhead does the Struts controller generate? This question must of course be seen in the context of writing your own controller or using any other framework. However, what is Struts overhead? What overhead does the use of form beans generate (in the sense of objects created, memory use, the use of reflection, speed) Custom tags (Struts' or other). Would they be applicable in a case like this? Wouldn't there be a massive creation of objects for every request? Please help me out here! I really want your knowledge on this!

You can load your property files into a table (generic schema is provided) and with this extension, by only modifying message-resources in the struts-config.xml your application will run WITHOUT ANY code changes. (See the readme.txt file included) This extension uses OJB (http://jakarta.apache.org/ojb) O/R mapping for database configuration and connection pool management. I have included a modified version of the (1.1b2) struts-example to demonstrate. I have tested this with Struts 1.1b2, and I'm sure it will work with 1.1b1 (If anyone requires a 1.0.x compatible, I can look at that also) I will get this project available as soon as I work through some cvs issues on sf.net: If anyone is REALLY itching to get their hands on it sooner, send me a email.
