Re: Installing a web change (was: importing a rpg orsqlrpg)

Joe,

Did your tone just get a little harsh or I am I reading something into it?

> How often is code ENTIRELY stable, Mark?  Be realistic. 

You made it sound as though this code is changing infrequently, for 
example, I consider JT400 to be "stable".  You get periodic new releases. 
If you are only changing your code once a month packaging it into a JAR is 
not a hardship.

Just talking about what I have observed.  I do not believe I passed myself 
off as an authority.  Please send me links to those white papers though. I 
do not believe it would be even remotely possible for the JIT process to 
be effected by JAR or no JAR.  I do think it could effect class loading 
however, which is also a performance consideration.

I may have been misunderstanding all along.  Are you saying you would like 
the .class files that are created for your JSP's to all be bundled in a 
JAR?  I am not aware of anything that would do that.  I am not sure it 
would even work if you did it manually, because the JSP compiler engine 
would probably just see the JSP as not having been compiled.  I could 
definitely be wrong on that though.

I follow an MVC approach to design.  I see the model as being the core API 
layer.  I develop this in its own project and package it as one or more 
JAR files that are updated on some kind of periodic basis.  We use these 
same JAR files in our Web application, our Eclipse plugins, and other 
Java-based UI.  My view layer is specific to the UI's I just mentioned, in 
the case of a web application it is JSP's that are used from Struts. These 
JSP's are logicless.  They just display the data they are given.  My 
controller layer in web applications is Struts.  This leads to a lot of 
little classes that go go out and get data from the model layer and 
present it in the view layer.  When I say loosely related, I mean that one 
of these classes does not interact directly with another similar class. 
They are only called by Struts and they only access our model and Struts. 
These are deployed as .class files under my WEB-INF/classes folder.

Hope this helps.
