Originally booking example in jee5 directory was for interoperability with Glassfish, WAS, Weblogic AS etc. Seam is now deployed into JBoss AS 5, which is JEE5 certified, so there is a question if it is still required to have both jee5/booking and booking examples in distribution.

I understand the concept, but it is quite confusing for the end user: - There is a "booking" sample that is dedicated to JBoss. Fine. I will not change/commit anything there. (The readme shoud state that this sample is taylored for JBoss and if the user as another AS it should look at the je55/booking sample instead

- there is a jee5/booking sample which is supposed to be AS "agnostic", but in fact it's not

(eg. the build process included specific JBoss libs,

there are specific lines for OC4J at various places etc..)

- the jpa sample took another approach, ie a resource-per-AS directoy + abuild file per AS... On your advice, I could describe what to do to get the booking/"agnostic-like" app to build and run on WAS, but IMHO as an end user discovering seam, it is much easier and faster to run a script that builds the ear file ready-to-be deployed and then inspect what's in the ear to mimic/adapt their own projects.

If not, i would have to describe the content of two files for the user to create by hand (copy/paste from the PDF which is tedious and error prone) and to describe the changes in half a dozen files the user haas to change by hand (build.xml, persistence.xml etc, component.xml, web.xml etc...) and also that the content of some files is not optimal for WAS (eg the ejb-ref in ejb-jar.xml is not necessary for WAS depending on how you configure JNDI for seam etc.., nor the ones in web.xml etc....-or i could just say "remove those lines-). The procedure will be a list of "add this line to that file", "remove those set of lines from those files" etc...

Also should I put the WAS specific lines in the files themself (has it has been partially done for OC4J and GF) ? in this case the todo list would be something like : "uncomment those lines" instead of "add those lines" but we will still have the "remove those lines" tasks..

As a compromise, maybe we could have a specific build.xml file per AS (that's includes all the required lib per AS) and a place to put artifact (files specific for an AS) that the end-user could copy itself by hand at the right place before building...but that is very close to have a full resource-websphere7 + build-websphere7.xml files...

Another point, the je55/booking/build.xml is not up to date (missing slf4j and still includes cglib, asm etc..) and the content of the META-INF directory should be split in two: the thing that goes at build time in the ear file and the files that goes into the ejb- jpa.jar file.

(eg. the build process included specific JBoss libs, Like? jboss-common-core.jar and concurrent.jar

Well, I would suggest including instructions for getting it working with minimal changes in the readme. You can add a comment to the specifc file like <!-- Not required in WAS 7 -->, and write in the ref guide that you don't need these (but they don't hurt) etc. But as this sample is likely the application people start with, IMHO it would be better to have an application that shows the "best way to run Seam on your AS". eg, in the doc I will describe three ways to configure the application to let Seam smoothy find the beans in the JNDI WAS namespace. If I give instructions to modify the sample app "with minimal changes" (see your comment below) to run on WAS, it will use the worse way (IMO) to do it (ie maintain the ejb3 ref in the config files) and people will build their apps on this without any real sample app that will use the best approach. If you are OK with it, for WAS, I will give instructions to build the booking application and get the "best way to run Seam on WAS v7", this will include a few extra steps (like remove the ejb-ref etc..)

Yes, I personally prefer this approach. What do others think? While I think the instructions are important, because they emphasize the changes that have to be made, I wish there was a build that would automate the modifications so that we lower the barrier to getting hands on. And yes, now that JBoss AS 5 is out, the jee5 app should be the first example any newcomer to Seam tries. Is there a place where we asterisk the default example? If so, we should asterisk the jee5 one. OK.. What I could do as an example for the jee5/booking sample: - commit the build-websphere7.xml file and resource-websphere7 directory like for the jpa sample (with tailored web.xml, persistence.xml, ejb-jar.xml file etc...) AND explain in the doc what to do if you want to do it by hand, starting from the "vanilla" resource/build files to get to the WAS v7 tailored files This could be done also for JBoss5, GFv2 and OC4J as this sample is mainly target for those AS and the bookingsample could then be deprecated...

WDYT? Two other ideas: 1) I would like that the general sample build proc look first for files in the resource-<as specific> dir THEN in the resource genral dir (ie copy the general resource dir in a temp place then override with specific files from theresource-<as specific> dir) . With that, we could only put in the resource-<as specific> dir, files that are really different from the base and not all the files as for now. The end user would directly see whant files have been changes (eg pages.xml, faces-config.xml,application.xml etc....never change )

2) I also would like to get 3 sub dirs in the "resource" folder: "META-IINF" for files that goes in the ear (ie application.xml), WEB- INF for the web module and JPA for file that go into the jpa-ejb jar

Again - I need to play more with this, but a few months ago it was still a problem (i.e. the IDE just become a fancy notepad :)

BTW, if m2eclipse imports an existing web project, it will set the web content folder according to maven settings. If you don't set warSourceDirectory to maven-war-plugin, the web content folder will be /src/main/webapp (the maven default web folder).

Here's the closes bug report I found: https://bugs.eclipse.org/bugs/show_bug.cgi?id=156417 I added my piece of mind to the issue report. I think that you are referring to the wrong bug. The user wanted to change the web content folder in the existing web project using a project property. That's really all I could find. Do you think we should just create a new issue?

> Can't the JBT wizard simply offer a better default when the project is being setup? I thought you wanted to configure a default web content folder for new projects. Right, that's what I mean. BTW, if m2eclipse imports an existing web project, it will set the web content folder according to maven settings. If you don't set warSourceDirectory to maven-war-plugin, the web content folder will be /src/main/webapp (the maven default web folder). Yep. But I figure without Maven 2, it should still offer a way to configure the location, as we have already mentioned elsewhere in the discussion.

I completely agree, but please report it to eclipse WTP please ;) note: it's always been configurable.

note: it's always been configurable. Just not through the UI. The Maven 2 eclipse:eclipse plugin sets it to src/main/webapp, so clearly it works by tweaking the .settings file.

Max, If you agree, I can add the following functionalities: - a project property page to change the web content folder of an existing project

- an Eclipse preference page to set the default web content folder

- saving the default web content folder if the user changes it within the Seam Web Project wizard (the new value would be available for the Seam Web Project wizard and for the Dynamic Web Project wizard)

What I don't understand--and please bear with my naivety about Eclipse plugin development--is why we can't offer some sort of "smart" editor that is aware of the properties defined in the pom.xml file and can resolve them when it needs a value (such as the JTA data source name). That is what I would like to do where we can - but will only work for our editors and projects. We don't control all of the IDE - sorry ;) Anyway, the editor is just *one* part of this - then there is the whole set of framework specific models in place, i.e. JSF and JPA provided by WTP has their own little model which expects things to be in a specific place and is not in any way extendable in this area (afaik). btw. jta datasource name is an example of something we don't really need to resolve since it only exists at runtime.... what we want to control is that when you want to do Hibernate queries from the IDE you use a persistence.xml that is configured to run in J2SE; but when deploying it should use the datasource name one - and this is not controllable with a mere property replacement because of how persistence.xml's are structured.

But I'll leave one statement/inquiry here. So you are saying that Eclipse basically has no native support for property substitutions of any kind in project files? I just don't see how the Eclipse developers missed this absolutely critical requirement for an IDE. For as long as anyone has been developing Java EE web applications, system administrators have been using all sorts of voodoo magic property replacement to get any deployable build artifact. Variations are just a huge fact of life. The IDE has to be able to deal with that reality and stop living in it's own ideal world that every value in a file is concrete. I'm saying *all* IDE's I know does not have property replacements support - not even intellij. If they have I missed it and would really like to get pointed to an example/docs anything. Please note there are two problems here: property replacement/understanding in editor/model and editors not being too much dependent on location of the file. Putting my problem solving hat back on, the best way I have found to deal with this situation, from many years of having to get the IDE to operate in the real world, is to have an environment switcher. It tears through the project and replaces configuration files intended for one app server with configuration files for another. Then, you can edit them...but of course when you are all done tweaking them (with permanent changes), you have to copy the files back to their source to check them in. Otherwise, the changes are just temporary for your immediate development needs. yes, that is what I've been doing too - or simply not depend on the IDE :) anyway, having such a environment switcher is "more or less" what the maven profile support does (except the destionation is always in the build result, anyone know if that can be changed/customzied?). What would be nice is to (for those locations where it is possible) to do the "inverse operation" by simply comparing the src and destination and just do an intelligent merge ;) Am I missing some obvious way to work? Put Maven completely aside for a moment and just focus on how to deal with different settings for different environment in any Java EE project. How is the problem solved? That is where we need to start when we discuss a solution. The problem is unfortunately normally solved with what I normally refer to as Ant voodoo ;) but yes, this is something better done face-2-face since its solution very much depend on what kind of 'property replacement' and what type of file you do it on.
