Below is my project structure
Same project is working fine with Weblogic 11G

I was able to resolve issue.
For people having similar issue.
Add weblogic.xml with following content in tag.
<container-descriptor>
<prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>
This step will remove stackoverflow error.
Later you might get some dependency error which can be resolved as required.

keycloak: "Failed to read artifact descriptor" error

I'm using the Java-based Keycloak server and attempting to run the demo examples. I'm a bit of a Java hack, so please pardon my naiveté.
I'm getting the error shown below -- any help debugging and solving would be appreciated.
ERROR [org.keycloak.services.error.KeycloakErrorHandler] (default task-7) Uncaught server error: java.lang.RuntimeException: org.eclipse.aether.collection.DependencyCollectionException: Failed to read artifact descriptor for org.keycloak:photoz-authz-policy:jar:3.4.3.Final
I had some trouble getting M2_HOME set so that keycloak could locate artifacts. I seem to be past that problem and now, but I'm not sure where to go with the above error. I've included some system info below. And if someone's really eager, the dockerfile is available.
I'm running v3.5.3 of maven:

Any insight?

I was able to get the examples to run by copying the project files to the server and compiling on the server. That seems strange to me -- a fat WAR seems like it would make more sense. That is, I wouldn't expect to have to have supporting libraries compiled on a the server, but that strategy allowed me to move on. Here are the commands I ran on my wildfly server (Dockerfile commands):
# Build and install keycloak example libraries
WORKDIR /opt/jboss
USER jboss
COPY --chown=jboss:jboss _srv/keycloak-demo-3.4.3.Final ./_srv/keycloak-demo-3.4.3.Final
WORKDIR _srv/keycloak-demo-3.4.3.Final/examples
RUN mvn -U clean install
WORKDIR /opt/jboss

Sonar runner (ubuntu) execution failed: com.mysql.jdbc.Driver

I've recently installed SONAR on a Vagrant box running UBUNTU.
Sonar service run fine, but when I try to run the sonar-runner I get an error related to jdbc connector.
I configured sonar to run with mysql database by changing the file "sonar-runner.properties":
sonar.jdbc.url=jdbc:mysql://127.0.0.1:3306/sonar?seUnicode=true&characterEncoding=utf8
sonar.jdbc.username=sonar
sonar.jdbc.password=sonar
When trying to start sonar-runner i get the following output:

ERROR:
ERROR: Re-run SonarQube Runner using the -X switch to enable full debug logging.
From my undertanding the jdbc driver is not found. I thought that during initalisation sonar-runner will get the required jar (like it does for other libraries).
I tried to "sudo apt-get install libmysql-java" but still get the same error message.
If that's the right thing to do (which I doubt) I should maybe add the jar to my classpath, but I'm don't know where that jar is actually downloaded and how to add it to the classpath.
Any idea on how to get that solved?
Thanks!!

I was looking at the wrong place!
Issue was not comming from the runner but from SONAR itself. I had to change de sonar config file '/opt/sonar' and restart it. In the setting page I now can see that sonar is running on mysql.
I'm facing a other issue with the runner, but it is not related to the issue above.
So basicaly make sure both SONAR and SONAR-RUNNER are configured to work with mysql.

I had the same issue. Issue was that mysql JDBC connector was not in my bash_profile.
So i add on .bash_profile :
export jdbc mysql connector to classpath
export CLASSPATH=${HOME}/sonar/mysql-connector-java-5.1.23/mysql-connector-java-5.1.23-bin.jar:$CLASSPATH
Hope it could help

How to fix this issue? Thanks in advance!

The first recommendation is to NOT install Eclipse from any Linux package manager or software repository. Instead, just get it from http://www.eclipse.org/downloads/. The builds that linux distro's install are often modified (mangled, some would say).

see https://askubuntu.com/a/695401/407641 for full instructions, ...
Highlights:
Don't sudo apt-get eclipse, that version is old!
Do download and install from http://www.eclipse.org/downloads
Do create a ~/Desktop/eclipse.desktop file. Note, the full path to the Desktop folder will be dependent upon your version of ubuntu.
