Re: problem launch simple app
I am just starting with Apache Isis and Eclipse as well, and I ran into
the same error.
From the error, it was apparent that Eclipse did not have one (or more)
jars in it's classpath. Since this whole thing is controlled by maven
(ugh), I guessed that something was missing from the pom.xml. I opened
the pom.xml located in the quickstart-webapp project in Eclipse, browsed
around, and found a couple of sections with the tag "<profile>" that
referenced "intellij" and "eclipse-m2e".
I noticed that the intellij profile had the following, but the
eclipse-m2e profile did not:
<dependencies>
<dependency>
<groupId>org.apache.isis.core</groupId>
<artifactId>isis-core-webserver</artifactId>
</dependency>
</dependencies>
I copied/pasted that xml from the intellij profile section to the
eclipse profile section (between the "</activation>" and "<build>"
tags). I then had (Eclipse had complained) to select the project in
Eclipse, right-click and select Maven -> Update Project... -> <OK>.
Once that completed, I was able to successfully able to right-click ->
Run As... on the SimpleAp-SERVER.launch.

Actually, I see that I applied the exact same fix to the pom.xml about 10
days ago...

Hi Maury,
and welcome to the mailing list.
Thanks for digging into this, and for providing a solution. I'll update
the archetype accordingly (you are also always welcome to raise a PR [1]).
Cheers
