Exception in thread "main" java.lang.ExceptionInInitializerError caused by java.lang.RuntimeException: Unable to instance KieServices

I am trying to get started with Drools 6x, and in eclipse, I have created a Drools project, which creates the boilerplate code to run a simple drl.
I have the drools runtime installed via Eclipse.
I have drools libraries, drools-core-5.0.1.jar,kie-api-6.0.0.beta4.jar,kie-internal-6.0.0.beta2.jar as External jars in my project.
Yet, when I try to run the following, I get the following error:

If you downloaded the zip of Jars from http://www.drools.org/, you're going to want to include every jar from /binaries in your project. Even the ones that seem like you won't use.
I had this same problem too because I assumed I only needed to use a few Jars, but it turns out they all depend on classes from the other jars in that zip folder.

I had this problem because I had both kie-api and kie-ci as dependencies in my pom file. I removed the kie-ci dependency and I'm not getting this issue any more.

I got this error while upgrading the Cucumber version in my Maven based project.
Turn out that I updated <artifactId>cucumber-java</artifactId> version from 1.1.5 to 1.2.4, but I didn't update <artifactId>cucumber-junit</artifactId> - it was still on 1.1.5.
On the moment I updated both to the same version, this error was gone.

Class file that your code depends on and it is present at compile time but not found at runtime. Look for differences in your build time and runtime classpaths.

Update cucumber-core,cucumber-java and cucumber-junit to the same version ( i have used 1.1.5 version ).The issue is resolved for me.

You have a missing classes in this package : com.jcraft.jsch.
If this package come from a third part library, then make sure that the jar contais this package inside a lib folder at the same level of your executable jar.
[Edit]
First: to add a third part jars in eclipse:
Right click on your project
Select properties -> Java Build Path -> Libraries tap.
Select Add External JARs
Navigate to your jars and press OK
Second: to generate an executable Jar file:
Right click on your project
Select Export -> Java -> Runnable JAR File.
This should work just fine.

ClassNotFoundException for TestApp when I start hazelcast/bin/run.bat

I started exploring hazelcast today I downloaded hazelcast-2.0 from the site, and following the ScreenCast provided in their site. I went to the bin directory and started run.bat from the command prompt.
I am getting the ClassNotFoundException. Can somebody please let me know what would have went wrong?
Caused by: java.lang.ClassNotFoundException: com.hazelcast.examples.TestApp

As noted in duffymo's comment, there is a problem in the .bat file as it adds the following to the classpath ../lib/hazelcast-${project.version}.jar.
Just replace ${project.version} with the version number you downloaded, or check the correct jar name from the lib directory and everything should work properly.
