Anybody knows how to solve this ?

You should add Microsoft JDBC Driver for SQL Server to your classpath. See:

Getting SSL and connection error with java function app in azure

I tried to deploy a Java and Maven function app to Microsoft Azure. The deployment goes well but when I try to run the program it gets all these errors. I start getting all these communication errors. Everything works locally but when published it doesn't. I don't know what info I should give here. But if someone has got the same problem it would be appreciated if someone could help. I can provide more info if asked but don't know what I should put here.

The answer was in the connection to MySQL. It used SSL=true but when changed to SSL=false it started working normally.

Sonar, Maven, Jenkins, MySQL - Cannot create JDBC driver of class 'com.mysql.jdbc.Driver'

Situation
We're running sonar with a MySQL database, jenkins and a build environment with maven.
Problem
When executing a jenkins job it is aborted with the message:
[ERROR] Failed to execute goal
org.codehaus.mojo:sonar-maven-plugin:2.0:sonar (default-cli) on
project playground_eb: Can not execute Sonar: Fail to connect to
database: Cannot create JDBC driver of class 'com.mysql.jdbc.Driver'
for connect URL 'http://192.168.1.220:3306': No suitable driver
Configuration
Servers
192.168.1.220 (Debian 6.0.6):
- runs Jenkins (# port 8080)
- Sonar (# port 9000)
- MySQL Database (# port 3306)
192.168.1.221 (Windows 7):
- runs Maven and the whole build environment
Configurations
The database was configured in the sonar.properties file - with localhost.
Sonar and its database were configured via the jenkins web interface - with the IP.
I guess this could cause errors but configuring the IP in the sonar.properties file causes sonar to not even start up anymore.

Just found the problem.
In Jenkins the Sonar database URL was set to
http://192.168.1.221:3306/sonar
Now I set it to the WHOLE JDBC-URL (including jdbc: ...) just like in the sonar.properties file
... and now it works.

Spring Batch - Connection Refused in some Unit Tests

If I run all(31) the unit test together, I get following connection error in 2 - 3 unit tests, however if I run those tests individually, the run successfully. Can you please guide me on this strange behaviour. I am using Spring 3.0.6, Spring batch 2.1.7 and Oracle XE database.

Something like this happened to me before. It was solved when I changed the IP of the database from 127.0.0.1 to 192.168.1.27 (the IP of my computer in my network, it can be found doing ip config in windows or ifconfig in linux). It might not be a permanent solution, but it dodges a bullet.
Just had the same issue:
Root cause:
All available connections spent
Solution:
Closing the connection after use.

Error during Sonar Configuration ( use Derby default DB )

I changed my Sonar DB from Oracle to Default Derby. I successfully configured the Sonar Server, however I have error during the integration with Hudson.

Error states that I can't found OracleDriver, Which I should not use anymore.
In my Hudson configuration, I have removed my oracle configuration and replaced it with these :
Any idea on what I configured wrongly?
fixed by changing the driver to "org.apache.derby.jdbc.ClientDriver". Turns out that the remarks "Do not set if you use default embedded" is a misleading.
