[OT] Critical Reviews of Core J2EE Patterns 2nd Ed
I'm thinking of buying the new Edition of the Core J2EE Patterns book. I've had a look around the internet for reviews of the book and most of them are incredibly glowing with very few criticisms. I wondered if this was because the book is truly excellent or my googling skills aren't up to scratch. Has anyone read the book and have any comments, negative or otherwise? Does the book live up to the praise it seems to be getting? The only critical comment I found on it (http://www.programming-reviews.com/Core_J2EE_Patterns_Best_Practices_and_Design_Strategies_0130648841.html) was that the examples given were JSP focussed ( the Controller idea is presented by JSP code) and weren't in themselves bad practice code. Is this really the case? Thanks for your comments Mark C - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
[OT] Static variables are evil? (was Question about Servlets Threads)
Craig, Just wanted to pick up on the comment: It's fair to warn you, though, that object oriented purists will frown on anything like this, because static variables (similar to globals in PHP) are the root of all sorts of program bugs :-). Explicitly passing things around creates *much* safer code. What sorts of problems do static variables cause? Does this also mean that you should avoid GlobalConstants type classes as well? On a related note, what're some good sources for such info related how best to OO your code? Is it just a matter of sticking to design patterns like a glue? cheers MC Craig R.

One option to consider is to store the current request and response objects into a static variable of type java.lang.ThreadLocal (perhaps in a Filter, if you're using Servlet 2.3, or a customized RequestProcessor implementation that does this in its process() method before executing the standard processing).

Accessing the servlet property at Action instatiation time
I'm trying to do some initialisation in my constructor. It calls other
classes and tries to pass the class the Application context. However, at
this stage, the servlet property has not been initialised in the Action
yet. I assume it must be possible to get the ServletContext from somewhere,
but I have no Idea where.
Any help would be much appreciated.
MyAction()
{
super();
OtherClass.doStuff(servlet.getServletContext());
}
cheers

html:link without URL rewriting
I want to render an html:link or html:rewrite tag without the URL rewriting. Is it possible to optionally turn off URL rewriting? Basically, we want to open a new session when we open a new window, and the only way we found was to turn off cookies and use URL rewriting to maintain sessions. We could then force a new session without terminating the current one by opening up a page without the jsessionid appended. We could hardcode the link but wanted to know whether I would be possible using the anything from the Struts tag-libs.

New Window, New Session
HI all, Have a Q about sessions. We're just looking to figure out how things work in struts at the moment, I want to start up a new session when I open up a new window. What is the best way of doing this? Basically the behaviour I want is for the Window A to have a link that opens a new window. That window will then be completely independent of window A with its own session. We think this could be achieved by NOT using html:link / html:rewrite for the new window link and simply hard coding the anchor tag. But IMHO this isn't very neat and maybe a new session can be started using Action mappings somehow? Thanks in advance for any guidance.

RE: date format
Going for a neat solution, in our project, we tried extending sql.Date and overwriting the toString method to output a date formatted with SimpleDateFormat in dd/MM/ format, We then used this data type as our Date type in our data beans so that when you do a bean:write on it, it will output the date in the correct format Unfortunately, we were using scaffold StorageBaseBean findCollection to get our data and for some reason or another, it was having some casting issues. We had to resort to creating xxxString version of the dates in the data bean that converts the dats into their correct format before returning the string cheers MC Desmond [EMAIL PROTECTED]To: Struts Users Mailing List [EMAIL PROTECTED] t cc: Subject: RE: date format 19/02/2003 04:03 AM Please respond to Struts Users Mailing List Use the SimpleDateFormat to do it so.

RE: [OT] Modeling tools
whilst we're on the topic of Oz beer, you can not overlook the James Squires range. They make some very tasy drops indeed. Squires ale pilsner are especially suited to breakfast, lunch and dinner. IMHO the problem with US beer is that none of the mass produced commercially available beers are any good... You hear of great micro breweries but if you're just over there visiting with no contacts, it's kinda hard to hunt down a good one. Then again, we were in Tampa...

[OT] Which Object Relational mapping tool?
Howdy all, This is not about struts really... But I figured it could be relevant for some people. If you know a better forum for relatively unbiased opinion, please tell me I'll take it there! Just looking into O/R mappers and have looked at (Briefly): Hibernate 2.0 beta 2 Castor 0.9.4.2 OJB 0.9.8 Does anyone know which is better for what? Which is the most robust and mature development? Have any recommendations of any other ones? Had some success/problems? Hibernate SOUNDS impressive and looks quite professional but I haven't used any of them... Again, sorry for spamming the struts mailing list and will take it elsewhere if it bothers people.

Velocity Tiles
Just wondering, is it possible to use Tiles Velocity together? I guess the question could just be, does Velocity permit you to import JSP tag libraries? thanks MC - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
[OT] Open Source Q Mailing List
Hey all, I'm just wondering, what would be a good forum/mailing list for Qs on general open source things like below? like What should i use for ... sorta questions. I'm quite new to the whole open source things and the range of things possible seems mind boggling. It's usually pretty hard to see what's good / bad or which is better (eg. struts VS turbine) and which we could use. The possibilities are exciting but can be pretty overwhelming at times. A reference to a general mailing list where more experienced people could provide me with pointers would be much appreciated cheers Mark C Ashish Kulkarni kulkarni_ash1312To: Struts Users Mailing List [EMAIL PROTECTED] @yahoo.com cc: Subject: Re: what I can use to display a Chart? 29/01/2003 09:39 AM Please respond to Struts Users Mailing List try http://www.object-refinery.com/jfreechart/ or www.ve.com Ashish --- [EMAIL PROTECTED] wrote: Hello, does any one use Charts with Struts? what lib / product you can recommend? thank you.

ActionForms Dynamically Created forms
Howdy all, I was wondering if/how you can use action forms with forms that have fields dynamically created through JavaScript? Basically, we have an ASP based site that we want to port over to struts as a proof of concept. On one of the forms. it looks up a number field to see how many instances of Copies information it needs to create and then create them using DOM. In effect you have a variable number of fields named CopyID1, CopyID2, CopyName1, CopyName2 etc etc. Was wondering how this could be represented using an ActioForm many thanks MC -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
DynaFormValidator Javascript Problem with multiple forms
Hi all, I have 3 forms on my page each having a field that is required. The validation stores these fields in an that can be obtained by caliing by required(). Unfortunately, my 3 html:javascript formName=blah1/ html:javascript formName=blah2/ html:javascript formName=blah3/ produces 3 required() methods in 3 different java script blocks. What this means is that when required() is called, only the last value, that is, the field from the form blah3 is ever returned whcih in turns mean that other two form do not valudate. Is there a way around this? Has anyone lese encountered this problem? Thanks Mark C -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
