Desperate - need help getting Ear project to deploy
Fred,
Thanks for responding. I
understand about supporting RAD. Would you have any suggestions on
downgrading the Project Facets?
By “downgrading”, I mean
I need to change “Dynamic Web Module” to 2.4, “WebSphere Web (Co-existence)”
to 6.1, “WebSphere Web (Extended)” to 6.1 and the Runtime to “WebSphere
Application Server v6.1”. To strip things down to the simplest scenario,
I’m following the example from https://www.ibm.com/developerworks/wikis/download/attachments/113607155/RAD_m2e-Nov.pdf?version=1
(the section “Creating Maven web project”). When I use the webapp-jee5
archetype, I get saddled with WAS 8.0 and Dynamic Web Module 2.5. Since
I’m not supposed to change the Project Facets outside of the pom, I’m
confused about how I’m supposed to go about doing this. This is
the “no-no” I referenced in my original post.
I’ve tried to do this using
the maven-eclipse-plugin:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-eclipse-plugin</artifactId>
<version>2.9</version>
<configuration>
<warContextRoot>SomeContextRoot</warContextRoot>
<additionalProjectFacets>
<jst.web>2.4</jst.web>
<com.ibm.websphere.extended.web>6.1</com.ibm.websphere.extended.web>
<com.ibm.websphere.coexistence.web>6.1</com.ibm.websphere.coexistence.web>
</additionalProjectFacets>
<jeeversion>1.4</jeeversion>
<wtpdefaultserver>WebSphere
Application Server v6.1</wtpdefaultserver>
</configuration>
</plugin>
…but the plug-in never seems
to show up in the Maven Console’s output when the project is building.
The Facets don’t change. I’ve looked at examples on the web,
but no one ever binds this plugin to a goal. They just use the default
bindings.

I can't provide help on RAD per se but the first thing you need to look at is the diff between a maven built ear and what's deployed by WTP.
FYI, m2e-wtp ignores the maven created target/appname folders. All that is published is defined under projectname/.settings/*.component.

I did another RAD
Clean then Republish. Now I’m back to app bootstrap only complaining

This makes no sense
whatsoever. Even if I get the .jar project’s class to be recognized,
the bizarre behavior between Clean/Republish vs. Run As… Maven install/Republish
is troubling.

Whoops. Let
me clarify that I have
<generateApplicationXml>false</generateApplicationXml>
In my .ear’s pom.xml
Interestingly enough, if
I do Project-> Clean… and then select all 4 projects that constitue
the multi-module project, the next Publish to WAS results in an app bootstrap
that only complains about the Dao from the .jar project missing. It
also complained about the MyFaces listener…seems kind of random. MyFaces
did initialize successfully though, so whatever.
Am I supposed to do a Clean
via RAD and let the workspace build automatically, or am I supposed to
use Run As… Maven install? Am I supposed to even touch Run As…
Maven install within RAD?

Hi,
I’ve been battling m2e and RAD
for a long time now in an attempt to convert an existing, working
project to a multi-module Maven project. I’ve managed to convert
the app and successfully deploy and run the app within a workspace. A
major problem was discovered when checking the project out into a second
workspace. I wanted to see what another developer would have to go
through upon checking the project out. Everything compiled just fine.
The problem was deploying the compiled .ear app to WebSphere via
wtp (Publish) from within the second workspace. I get stack traces
all over the place complaining about ClassNotFoundException’s. The
deployed .war can’t even find classes defined within its own web.xml (the
bootstrap class, listeners, servlets, etc.).
Looking back to the work I did
in the 1st workspace, I know that I was messing with wtp-related
settings (Deployment Assembly, Build Path, etc.)…essentially all “no-no’s”.
So, I have no clue how the heck that app is working and running within
the 1st workspace. I had jumped into the conversion before
I had stumbled upon this:
https://www.ibm.com/developerworks/wikis/download/attachments/113607155/RAD_m2e-Nov.pdf?version=1
(*note this is June 2012. I had stumbled upon the Nov. 2011 version.
I’ve been attempting this Maven conversion since May). I
just discovered this new version while typing this, but I’m not seeing
anything that will resolve this problem.
I can build the project via mvn
install in the command line or through RAD (Run As… -> Maven install)
and manually deploying either the .ear or .war via Admin Console to WebSphere
works (the app starts with no errors and I can actually navigate to and
use the app). So, I know that the issue lies with the .ear generated
by m2e within /target in my workspace. I’m thinking that the problem
has to be the way I’ve configured the maven-ear-plugin and the maven-war-plugin.
Then again, while typing this,
I was able to get the app bootstrapping without ClassNotFoundException’s
for classes within the .war (everything listed in web.xml). It only
griped about not finding a Dao object in my .jar project dependency that
app bootstrap class uses to initialize Hibernate. After I added the
.jar as a dependency to the .ear project, as an experiment which failed
to solve the ClassNotFoundException’s, removed the .jar dependency from
the .ear project, removed the app from WAS, cleaned WAS, and then added
the app back, I get ClassNotFoundException’s for everything again. Wth?
Can someone please help me sort
this out and get this to successfully deploy from within RAD to the test
WAS 6.1? With the situation described in the last paragraph occurring,
I am extremely confused as to what the heck is going on here.
I have to be able to do deploy
from within RAD to the built-in test WAS 6.1 via wtp (Publish). I’m
not the only developer, but I’m the only true Java/web guy here…so this
stuff has to be as simple as possible. This is also holding up me
implementing a Maven Repo and CI setup. I’ve been pampered by using
Maven in combination with NetBeans + Tomcat 7, so this m2e experience has
been beyond frustrating. I’ve been using RAD + WAS 6.0/6.1 for the
past 3 years, and it’s been a dream of mine to get my apps at work converted
to Maven projects.
Specifics:
RAD – v8.0.4.1
WebSphere – v6.1.43
M2e – 1.1.0
M2e-wtp – 0.15.2
I don’t use the embedded Maven
that comes with m2e. Via RAD’s preferences, I use my external Maven
3.0.4 installation.
I’ve taken advantage of some of
the features introduced in m2e-wtp 0.14 and 0.15:
1.) RAD -> preferences… ->Maven -> WTP integration: unchecking “Maven Archiver generates files under the build directory” specifically for my .war project and then all projects as directed. This allows me to republish to WAS via wtp via “Run server with resources within the workspace”, which allows me to avoid having to manually remove the app from WAS every time I wish to republish. MANIFEST.MF and pom.properties are then put within src/main/webapp/META-INF, which I exclude from SCM.
2.) The defaultRootSource tag for the src/main/webapp wb-resource entry within org.eclipse.wst.common.component.
3.)
My .ear project
requires a <finalName>, under the <build> section of the pom,
that matches the Ear project’s name within the workspace. This allows
me to right-click on the ear project and open the WebSphere Application
Server Deployment.
I need to switch the CLASSLOADER
policy to PARENT_LAST due to us being stuck with JSF 1.2, specifically
MyFaces. IBM packages JSF 1.1, specifically Sun-RI (pre-Mojarra)
into WAS 6.1 (argh). I’m looking forward to WAS 8. I deleted
the wtp-generated application.xml. pom.xml is generating the application.xml
by default.
I am not using skinny wars…for
now. I tried a skinny war setup and had the same ClassNotFoundException
problem. I want to get something simpler working first.
Here’s the build portion of my
.war’s pom:
<build>
<!-- Changes

<finalName>SomeApp</finalName>

</archive>
</configuration>
</plugin>
</plugins>
</build>
The build portion of my .ear’s
pom:
<build>
<!-- The

<finalName>SomeAppEar</finalName>
<plugins>
<plugin>

<!--
<archive>
<manifest>
<addClasspath>true</addClasspath>
</manifest>
</archive> -->
</configuration>
</plugin>
</plugins>
</build>
Here’s the .war dependency as
listed within the .ear’s pom:
<dependency>
<groupId>com.some.group.id</groupId>
<artifactId>SomeAppWar</artifactId>
<version>2.0.0-Final</version>
<type>war</type>
<scope>compile</scope>
</dependency>
Sorry for the novel…just trying
to describe everything necessary to understand the situation.
