The sample fails on the server-side because
somehow the EMF does not get initialized.
I've imported the sample into Eclipse 3.6 on
Windows 7 and running the LoadExpensesDB
module via Debug As menu item of Eclipse
Property Context Menu.
Can anybody please shed some light on how to
initialize the server-side DB and services?
The exception is:
[ERROR] javax.servlet.ServletContext log:
Exception while dispatching incoming RPC call
com.google.gwt.user.server.rpc.UnexpectedException:

com.google.gwt.sample.expenses.client.DataGenerationService.getCounts()'

Esfand,
You need the RC1 version of the Google Plugin for Eclipse also. You
can download it here:
http://code.google.com/webtoolkit/download_2_1_rc1.html
Please post back if you're still having problems.

Hi David. Thanks for your reply.
I am already using GPE 1.4.rc1-201010102248 with Eclipse 3.6
I am not using any of the jar files download by maven, instead I'm
using GAE/J 1.3.8-prerelease and GWT.2.1.0.RC1 distributed
via thezip-file ( http://code.google.com/webtoolkit/download_2_1_rc1.html
)
I tried GAE/J 1.3.7 with the same result.
I created the eclipse project files using mvn eclipse:eclipse to
make sure DataNeucleus gets a chance to do its enhance magic.
When I select "Debug As" to launch the app, a dialog box pops-up
containing the following two lines:
An error has occurred. See error log for more details.
Argument cannot be null
Regardless, the server starts and the browser displays the
buttons, etc.
Thanks again and please let me know if you need more info
for trouble-shooting.

Hi Esfand,
At present, you also need to run mvn package to ensure that
DataNucleus enhancement (attached to compile goal in the pom) runs and
that the static webapp files are moved into place under the target
directory. This will be addressed in the release version of the
plugin. Does that resolve the issue for you?
Thank you,

In fact I did run 'mvn package' before 'mvn eclipse:eclipse'
based on your advice I read on this forum a few days ago.
I just ran the sample using 'mvn gwt:run' directly
(after running 'mvn pakage') In other words no Eclipse in
the way and interestingly the same error happened.
I'm using maven 3. I doubt it, but can it be the reason?

I forgot to mention that when running 'mvn gwt:run', I see a bunch
of errors and warnings such as the following:

Esfand,
I'm able to mvn gwt:run the Expenses sample with the following POM
changes:
Change DataNucleus version back to 1.1.5
<datanucleus.version>1.1.5</datanucleus.version>
Upgrade gwt-maven-plugin to version 1.3.2.google (resolves the ASM
error below):
<artifactId>gwt-maven-plugin</artifactId>
<version>1.3.2.google</version>
Add xalan dependency:
<dependency>
<groupId>xalan</groupId>
<artifactId>xalan</artifactId>
<version>2.7.1</version>
</dependency>
Change maven-gae-plugin version to 0.7.2 (latest)
Add Google snapshot repo to pick GWT 2.1RC:
<repository>
<id>google-maven-snapshot-repository</id>
<name>Google Maven Snapshot Repository</name>
<url>https://oss.sonatype.org/content/repositories/google-snapshots/
</url>
<snapshots>
<enabled>true</enabled>
</snapshots>
</repository>
In expenses dir, copy files needed by the data
expenses> cp src/main/webapp *.txt .
expenses> mvn clean package
expenses> mvn gwt:run
You should then be able to browse to LoadExpensesDB.html to generate
sample data, then to Expenses.html to use the app.
I'm using Maven 2.2.1, FYI.
It is not yet possible to run from Eclipse, at least not easily, but
changes to Google Plugin for Eclipse for 2.1 GA should fix that.
Thanks for your patience!

Apparently the gwt-maven-plugin 1.3.2 has a dependency on

Hi Esfand,
Do you mind trying again? Once upon a time, Maven would sometimes time
out waiting for plexus jars from central and running it again a few
minutes later would resolve... Failing that, could you try it with
Maven 2.2.1 just to rule out any issues related to Maven 3?
Thank you,

Not at all! I appreciate if you post the exact XML snippet for
adding the dependency. I'm not sure if I have the right info
especially the version of the package..
Thanks for your help.

Hi David,
I ran 'mvn clean package' with maven3 a couple of more tomes.
Same result happened.
Then I used Maven 2.2.1 same error (printed in a different
format happened) plus a couple of more warnings and errors.
Below are excerpts containing all the errors from the
printout. It seems that DataNeucleus expects to see the
resources folder under main with the log configuration file
in it. The other plugin needs XmlStreamReader class. I
had a quick web-search for XmlStreamReader. It is
apparently obsolete, but then there is another routine with
the same exact name under javax package.
Regards,
ES.

The Expenses pom.xml has been updated in trunk:
http://code.google.com/p/google-web-toolkit/source/browse/trunk/samples/expenses/pom.xml
You should now be able to run "mvn gwt:run" to run in hosted mode or
"mvn package gae:run" to run in production mode. Hit
LoadExpensesDB.html first to load sample data, then Expenses.html to
use the app.
The project will import into Eclipse using m2eclipse or "mvn
eclipse:eclipse". To run from Eclipse with Run as | Web Application,
there's still a GPE fix coming...

Thnaks! This is going to be a very useful pom.xml file.
So long, greeting (sample.).
Just a reminder, the three .txt files from src/main/webapp
folder still needs to be moved to the project's root folder
in order for the sample to work.
By some minor change it even works with newly released
appengine-1.3.8 and Roo-1.1-RC1.
It can even work with the gwt-2.1.0-SNAPSHT form the
maven central. I just wonder how often this snapshot is
going to be updated. Hopefully with every GWT build of
the Hudson CI server.

Hi CoderInAbstract,
I had this problem because the DataNucleus plugin
wasn't able to enhance the classes. It's very likely
that this is your problem too.
If that's the case:
1) Are you using the latest pom.xme from the trunk?
(The one David posted about)
2) Did you wiped-out your local maven repository before
running 'mvn clean package' ?
3) Did you copy the three text files to your project's root
folder? (where the pom.xml is)
4) Are you using the latest Google Plugin for Eclipse RC1?
(It's version is 1.4.0.rc1-201010102248)
By the way which OS are you using?

Thanks...it works now outside eclipse in terminal...os used macosX
10.6
however when run mvn eclipse:eclipse command and import as
project...cant get it to run.
any steps as above from would be great to help..thanks in
advance....seems like after mvn gwt:run in command line, the same
project having mvn eclipse:eclipse doesn't work afer importing as
project in eclipse and running as webapplication, must be more to it.
Again..thank you

Now the (almost) final GWT 2.1 version of the pom.xml
file is on the GWT SVN trunk ( http://bit.ly/pom-xml ). and
the instructions to import the sample to Eclipse and
running it is here ( http://bit.ly/pom-ins ). It is still points
to GAE 1.3.7 and Roo M2, but you can change them to
the latest and it works..
Regarding the import to Eclipse, don't use
'gwt eclipse:eclipse', instead import the pom.xml file
directly into Eclipse. For this, select
File / Import / Maven / Existing Maven Project
in Eclipse, This will create the .project, .classpath
and .settings for you.
The good news is that now, like normal Eclipse
development, we can use 'Run As' or 'Debug As' to run
the sample and it works (I mean GPE works now)
Cheers, /es

I think I forgot to mention that in order to use the pom.xml
file from the trunk, you need to change the line
<gwt.version>2.1.0</gwt.version>
to:
<gwt.version>2.1-SNAPSHOT</gwt.version>
because the GWT 2.1.0 release is not in the repository yet.

Thanks...
After import as maven project...does not recognize automatically as
gwt project. Need to go to project properties and set it up on Eclipse
3.6.
WebToolkit and GAE setup needs to be manually setup.
Also, war file location needs to be adjusted...got it to run with src
\main\webapp or target and unchecked launch and deploye from
directory. Seems like almost there (Don't know if this is related to
Eclipse 3.6, but have not tried with Eclips 3.5). Any thoughts would
be appreciated..thank you.

A new version of Google Plugin for Eclipse will ship with GWT 2.1
which will fix the Maven integration issues you're seeing. Until then,
you can run the Expenses sample with "mvn gwt:run"

Hi CoderInAbstract,
I'm also using Eclipse 3.6. I use Maven 3.0 but Maven 2.2.1
worked too. I did the same changes that you described too.
In addition, I ran 'clean package' using 'Run as maven build'
from within Eclipse before 'Run as WebApp'. I didn't get
any error and I'm able to set breakpoints and step through
the code. So, there must be a difference between
Windows and Mac in this respect.
Bad news is that, after reading David's post (just before
this one), I went ahead and changed some code and
then tried to run the program again, at that time Eclipse
totally hanged while DataNucleus was running. So, it is
possible to debug code as long as after any code
change, we run 'maven package' again.
Regards, /ES

Thank you ....that worked!!..the only change from my comments above is
to have to set the Google webapp path in project properties to target/
expenses-0.1.0.BUILD-SNAPSHOT and check the launch and deploy from
this directory check box.
Again..thanks for all the tips on this subject in making this work.
