Re: car-maven-plugin and GEP

Hi bongosdude, yes you make a good point. I suppose my answer would depend on what exactly you're trying to accomplish. If you want to import existing J2EE artifacts into Eclipse my previous instructions obviously apply and will work. However, if you want to establish your development environment such that your J2EE artifacts will build successfully in both maven and Eclipse you might consider an approach that is somewhat similar to what we do for the GEP development. For the GEP we maintain both our maven files (e.g., pom.xml) and the Eclipse files (i.e., .classpath, .project files) in our SVN repository. This allows us to import our development projects into our Eclipse workspace and thus we operate directly on the artifacts/files (as they were extracted) from SVN. Some of these techniques are documented on our website here:
-----> http://geronimo.apache.org/development-tools.html#DevelopmentTools-DevelopingGEPandGeronimo 


These work very well for us, but I'm sure there are other alternatives that might 
work for you possibly using the maven Eclipse plugin that you mention, or maybe 
the m2eclipse plugin which seems to be heavily used. Does this help ??

Tim,

I have verified that those steps you laid out work perfectly. However, my
question is: there are two environments here that we have to manage: maven
and GEP. Why does not the command: maven -Dwtpversion=1.5 eclipse:eclipse
work here? When team members copy/paste sources into imported EAR projects,
the team lose the synchronization with SVN repository. Or I am missing
something here?

Thanks.

Tim,

I got the latest source from geronimo svn trunk and step 4 works now. I
successfully deployed calculator using GEP as you described in step 4.

Thanks

Yes, this is what I am trying to do. 


- Your step 4: what method should I use to test deploy of calculator.ear
to my local geronimo-2.2-snapshot? It seems that GEP fails to know how to
deploy to geronimo-2.2-snapshot runtime.

Thanks

Hi bongosdude, here are the steps I used to accomplish this for the

"calculator" 
sample:


1.  Ensure that you have a Geronimo server defined in Eclipse (Trunk for
example)

2.  Build the 2.1.2 samples in maven


3.  In Eclipse, import the resulting EAR file from Step #2 (i.e., 
calculator-ear-2.1.2.ear) and be sure the runtime defined in Step #1 is
specified 
  as the target runtime. This will create three projects in Eclipse for
you: 
calculator-ear-2.1.2, calculator-ejb-2.1.2, calculator-war-2.1.2.


4.  Just to ensure that everything is working fine up to this point I

would go 
ahead and deploy the EAR file imported from Step #3 to your Geronimo
server 
defined in Step #1. Ensure that it deploys and then invoke the WAR file:


        -----> http://localhost:8080/calculator-war-2.1.2/

5. Undeploy the EAR file deployed in Step #4, and stop the server


6. Copy/Paste the three java files in SVN (i.e., in 
\samples\tags\samples-parent-2.1.2\samples\calculator\calculator-ejb\src\main\java\org\apache\geronimo\samples\slsb\calculator) 
into the Eclipse package org.apache.geronimo.samples.slsb.calculator for
the 
calculator-ejb-2.1.2 project. This package should have been created for
you 
during the import in Step #3; if not, go ahead and create it yourself
prior to 
the Copy/Paste.



7.  For the calculator-war-2.1.2 project create this package: 
org.apache.geronimo.samples.calculator



8.  Copy/Paste the single java file in SVN (i.e., 
\samples\tags\samples-parent-2.1.2\samples\calculator\calculator-war\src\main\java\org\apache\geronimo\samples\calculator\

CalculatorServlet.java) into the package created in Step #7

9.  In Eclipse, add the calculator-ejb-2.1.2 project to the build path

for the 
calculator-war-2.1.2 project to ensure that everything builds


10.  To demonstrate that you can debug the source code, set a breakpoint

on line 
56 of the CalculatorServlet.java source file


11.  Start the Geronimo server in "debug mode"

12.  Redeploy the calculator-ear-2.1.2 to Geronimo server

13.  Ensure that it deploys and then invoke the WAR file again:

        -----> http://localhost:8080/calculator-war-2.1.2/

14.  Finally, click the "add" or "multiple" Operation button on

resulting web 
page and the Eclipse debugger should stop at the breakpoint you set in

Step #10

That's it !! Is this the information you're looking for though ?? If

not, please 
let me know. Thanks much and good luck !!

Tim,

I would like to rephrase my question: How can I do to import the
samples

calculator into eclipse IDE and use GEP to debug, deploy and test? 
(repository at

https://svn.apache.org/repos/asf/geronimo/samples/tags/samples-parent-2.1.2)?

I can use maven outside eclipse to build, install the sample to local
repository and deploy from console or from gshell. But I still do not
know
how I can import samples / projects that are set up with
car-maven-plugin
into eclipse?

Thanks

Hi Tim,

I setup my project using maven car-maven-plugin (i.e. I looked at the
sample calculator). To create eclipse plugin I ran the command

mvn -Dwtpversion=1.5 eclipse:eclipse

and then import the newly created eclipse project into eclipse IDE.
However, it seems that my eclipse GEP does not know how that those
projects are geronimo J2EE projects.

Can you start from the geronimo  sample (bank, calculator...) and show
us
how to import those sample into eclipse IDE, run a debug with WTP
local
server....

Thanks

Hi bongosdude, in the Trunk and 2.1.4 versions of the GEP there has
been

a lot to 
work to support Geronimo server plugins and custom assembles. Some of
these 
capabilities have been documented below. You should be able to do all
your 
development in the GEP and not have to maintain dual environments.

From

the GEP 
you'll be able to create custom server assemblies and export your

Eclipse

J2EE 
projects as Geronimo plugins. Could you read the following and

comment on

whether 
this meets your needs ?? If not, we need to determine what doesn't

meet

your 
needs and analyze according. Thanks again.

I have learned quite a lot for the last two weeks about Geronimo.
Developing
J2EE applications has so many aspects and setting up environment for
development, QA and deployment are 3 main areas that really concerns
any
J2EE developers. I have followed steps by steps of many GEP samples
and
tutorials through GEP eclipse plugin. Then I just learned last week
from
this forum on how to setup J2EE projects with Maven using
car-maven-plugin.
I felt very confident toward Geronimo as my next J2EE platform.
Today I
would hope that someone can give me some guidance again on how to
make
GEP
works with car-maven-plugin

1. I have successfully setup my J2EE projects by mimicking and
looking
at
geronimo sample calculator. I have successfully deployed my project
tomcat
plugin to my local geronimo server. I love maven and its dependency
management.

2. However, now GEP does not know that my project is targeted for
geronimo
local server. I can go to each of my sub project (war, ejb) and turn
on
its
project facets and runtime settings for geronimo. But it is quite
tedious
and that also means that I have to take care of two environments:
GEP
vs.
car-maven-plugin

So my question is: "While it is good to setup maven J2EE using
car-maven-plugin which is quite helpful for more real J2EE projects,
developer would still love to use eclipse IDE to develop, test
through
GEP?
Can car-maven-plugin be able to generate eclipse metadata to target
its
sub
projects for geronimo runtime?"



Thanks again for any helps.
