Look's like the aspectjrt.jar is missing in your classptah. Download & add it to your classpath.

How to set the classpath in Windows Command Line correctly

I have made many attempts to enter a command to run a JAR file correctly from the terminal, and I am 100% sure that all the JAR files and such are in the given paths, but I keep getting a ClassDefNotFoundException. Does it have anything to do with the way that I am entering the command?

Note that the class "org.jitsi.service.libjitsi.LibJitsi" really is in a JAR file whose real location is in the folder "C:\Users\Anna\Downloads\Windows64_Libjitsi", which is the class path for JAR files that I am attempting to specify on the command line.
You have add the JAR to the CLASSPATH, not the folder which contains this JAR. So the -cp argument should something be like this C:\Users\ANNA\Downloads\SimplifiedConnectionProvider.jar;C:\Users\ANNA\Downloads\Windows64_Libjitsi\the_name_of_the_JAR.jar.

Any help would be appreciated for the same. I have tried adding the common logging jars but no luck.
Hi there are quite a few third-party library's required for AWS to work. The ones below are the extras packaged with the SDK download. I seem to remember there being one missing though so let me know if this doesn't work and i'll check my dependencys.
All of these can be found in '\aws-java-sdk-1.9.1\third-party'
aspectj-1.6
commons-codec-1.6
commons-logging-1.1.3
freemarker-2.3.1.8
httpcomponents-client-4.3

Thank you in advance.
You miss the httpclient.jar in your classpath. Download it and add it to your classpath.

I have no clue what could be causing this.
You must install the troublesome program to a folder without spaces in the full name.
