Using Eclipse 3.1, and WTP 0.7.

If you have an existing war-file it's easy to import it as a Dynamic Web
Project. Just do File -> Import -> WAR-file and step through the wizard.
You may get duplicate entries in the library path for jar-files under
WEB-INF, but these are easy to remove in the resulting project's properties.
I've used this wizard successfully with various war-files such as the
OpenLaszlo-servlet and the Spring framework sample web applications.

That's good to know - thanks much...
It doesn't seem like it would be possible to coordinate the source changes
you make via the imported war (which you would have to package yourself
before the import) with the svn repository... or am I missing something?

Save Fredrik's response, I've not received any help on this. Am I right
to assume that this toolset can't be used to work with projects that are
created outside of WTP? Or does it require much tweaking of obscure
configuration files? It certainly isn't possible to do this through the
UI. Or is it?
Thanks in advance for you insight...

If I'm understanding you correctly, it is possible (and fairly easy) to
import a project created outside of Eclipse, but I don't think it's
possible (or at least not reasonable) to use both IDE's with the same
source directories. Once you import into Eclipse/WTP, you need to work
in there. When I did this, I left the original source folders on disk
untouched until I had everything working in Eclipse.
To run/debug in Eclipse on Tomcat, you need an installation of Tomcat on
your machine which you then set up as a server in Eclipse.
If that's not what you are asking, then please clarify exactly what you
are trying to do.

I could have a semantic problem here - why are you saying 'both IDEs'. I
(likely wrongly) consider Eclipse to be the IDE, and WTP to be an
extension to this IDE. Likewise, I think of Java, SVN, etc, to be
extensions to the IDE.

Is import the right term? I created a new Java project, pointed the
project to the 1st root project directory, and it nicely (and completely)
set everything up. It didn't change the checked-out directory structure,
which subsequently means I can easily update/commit changes to it. Import
is a completely different menu item from the UI point-of-view - or is it?
For this project then, how do I import it into Eclipse/WTP? Via packaging
it as a war (as suggested earlier)? That just doesn't feel right. (Heck,
I may be stumbling on countless semantic issues here and not even coming
close to asking the right sort of questions...)

That's really my goal here - WTP or not - I want to run/debug this open
source project under Tomcat within Eclipse. Was able to set up a Tomcat
server within Eclipse, but then have to tackle the issue of running this
project within it.

How did you create the project outside of eclipse? Whatever you used to
do that is what I mean by "the other IDE". If all you have is a bunch
of .java files you created with a text editor, then the import will be
no problem.

Yes, it is. Import is for pulling an already-existing java
program/project into an Eclipse workspace, so you can work on it in
eclipse instead of in whatever you used to create it previously. If you
got eclipse to recognize the project by just pointing it at an already-
existing java folder arrangment, then I guess you made "import"ing
unnecessary.

Once you have it showing up in the project explorer on the left side of
Eclipse, it's already there, and you don't need to import it. Creating
a .war is "Export"ing it. You don't need to package it as a war unless
you are going to move it to a different server, completely outside of
Eclipse, such as a production server (as opposed to your development
installation of tomcat).

You need to set up a "server" in your eclipse workspace. Go to "New |
Other | Server | Server" and let the wizard walk you through it. Then
you start the server with your project on it from the menus, or the
shortcut button.

This is an awful problem in WTP. I have several projects internally in
my company which I would like to work on in eclipse however we're forced
to use proprietary software as the only other solution is to hack away
at the .wtpmodule/.project files. I hope that for myself, the other
people like yourselves, and the success of the WTP that this issue will
get the attention it deserves.
I suppose the most annoying part is that one knows it's possible, the
functionality is there, but you just can't access it through the
interface. Adding a web project aspect to a current java project or even
a simple project is just not possible out of the box.
Grrrr :(

Do the developers of WTP acknowledge this (for me, brutal) shortcoming?
I'd love to know that they were aware of it and planned on doing something
about it.
Anyway... Is there anything around that describes hacking
wtpmodule/.project files? I did stumble on that while searching for an
answer, but the info was incredibly fragmented.

Just to acknowledge the frustration, yes, "the developers of WTP" do
acknowledge issues and have recently posted
http://www.eclipse.org/webtools/jst/components/j2ee/proposal s/WTPFlexibl=

Well ... to be honest, I'm not sure exactly what you and others have to =
"hack" in wtpmodules
and .project files, exactly, so be sure to open bugs/feature requests pe=
rhaps detailing
what you'd like to accomplish and what's preventing it -- if not address=
ed in proposal document.
My current best guess is not all your problems will be solved in the 1.0=
(Dec) time frame, but
hopefully progress will be made, and your continued feedback and 'use ca=
ses' will help
establish priorities.
Thanks,

I'm afraid if I suggested something it would be too vague. My specific
need, right at this moment, is to make changes/run/debug Xwiki via
Eclipse. I'd like the project setup to be nearly as simple as 'Create new
project based on existing source'. (Key word there is 'nearly' - these
sort of projects are more complex that a simple Java project.) And, if
that can't work, expose a UI that allows one to describe where various
resources are located. Finally, the organization of the project in the
filestem can't be tampered with as it needs to be updated/committed
against a remote repository.
Would 'checking out Xwiki, work with the project in Eclipse' be enough to
define at least one use case for your proposal?
As for editing .wtpmodule files - I'm clueless.

I've tried this earlier, and this was one of the reasons I finally came
over to this group to ask for help. It walks me through a dialog to
choose a Tomcat instance - no problem here. Next dialog shows an empty
list called 'Available Projects'. No clue on how to run this project
under the server I just set up.
One thing I'd love for someone to try - download the Xwiki project, and
try to do the following, and document the steps taken:
1) Setup a project for it in Eclipse
2) Preserve the existing project directory structure so changes made could
be synchronized with a repository.
3) Run/debug the project within Eclipse under Tomcat. I wouldn't expect
it to run great without the additional setup required (e.g. database), but
that's ok - just getting it starting up broken is enough for me.
I'm calling out Xwiki here because I'm using it in my current production
cycle, but it could be any servlet-based project not originally created in
Eclipse/WTP.

That's quite easy to do, once you know what to look for.
I have written a little howto on how to adapt a project to WTP.
Here is my setup for xWiki:
1) download a Xwiki source tarball (or get the source from a cvs
checkout)2) in Eclipse, define a new Java Project and select the folder where you
put the xWiki src as the project root, call your project xWiki3) eclipse imports your project, define your classpath, and import all
the libraries from the lib directory.4) go to the resource perspective and edit the .project file to read:
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-==-=-=-=-=-=-=-=-=-=-=-=-= -=-=-=-=-=
<?xml version="1.0" encoding="UTF-8"?>
<projectDescription>
<name>xWiki</name>
<comment></comment>
<projects>
</projects>
<buildSpec>

<nature>org.eclipse.wst.common.modulecore.ModuleCoreNature</nature >
</natures>
</projectDescription>
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-==-=-=-=-=-=-=-=-=-=-=-=-= -=-=-=-=-=
5) create a file named .wtpmodules which read:
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-==-=-=-=-=-=-=-=-=-=-=-=-= -=-=-=-=-=
<?xml version="1.0" encoding="UTF-8"?>
<project-modules id="moduleCoreId">
<wb-module deploy-name="xWiki">
<module-type module-type-id="jst.web">
<version>2.3</version>
<property name="context-root" value="xWiki"/>
<property name="java-output-path" value="/bin/"/>
</module-type>
<wb-resource source-path="src/main/java"
deploy-path="/WEB-INF/classes"/> <wb-resource source-path="src/main/web" deploy-path="/"/>
<dependent-module deploy-path="/WEB-INF/lib"
handle="module:/classpath/lib/lib/xmlrpc-1.2.jar"/> .......... [ copy the lib from .classpath and replace
{<classpathentry kind="lib" path="} by
{<dependent-module deploy-path="/WEB-INF/lib"
handle="module:/classpath/lib/} I dont' copy the 118 lines here, because they are all
the same, more over there is probably some not needed jars to run the web app in the lib folder]
</wb-module>
</project-modules>
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-==-=-=-=-=-=-=-=-=-=-=-=-= -=-=-=-=-=
6) The only missing bit is the web.xml file which has to be in the
WEB-INF folderfor xWiki, there is two of those in src/main, pick one of them and copy
it to src/main/webapp/WEB-INF
7) setup xWiki as you would normally do (edit your xWiki.cfg file qnd/or
setup your database)
8) you are now ready to start your webapp in Eclipse: right click on the
project and select "Run As..."->"Run On Server"as you would do for a standard dynamic project.
Hope this is clear enough.

For the team behind the WTP - what can be done to expose this

files? I think that there is an expectation that a project like this can
be setup with WTP - you can see it in some of the responses in this
thread. Perhaps someone could write a FAQ entry about this scenario?
That'd be great and would more than suffice while the implementation
details are worked out.
