    Are both your jar and the joda.jar files in the same directory? How are you running the jar?

    I am running the jar with the command

    java -jar client.jar

    Here is how I am exporting it in eclipse.

    It's being exported as a jar file, not a runnable jar.

    Forget the IDE for the moment. Go into the bin directory and use the command line to jar the files (with the appropriate manifest file). Then place this jar in a directory alongside your other libraries and try to run. I mention this because my foggy memory recalls something about Eclipse packaging jar's in a strange way...trying it by hand will support this and let you know your manifest is technically correct. If so, I remember my workaround being an ANT script (you could also try to export as runnable jar)

    I am unsure of how to compile from the command line with my setup. I have 3 packages and I don't know how to include them with the javac command.

    The jar command is used to build a jar file, not the javac command.
    Here's a sample batch file I use to build a jar file:
    REM Make InstantPP.jar file 
    %DEV_DRIVE%
    SET JarName=%DEV_HOME%\JavaDevelopment\NormsDev\InstantPP\InstantPP.jar
     
    cd %DEV_HOME%\JavaDevelopment\NormsDev\InstantPP
    jar -cmf InstantPP.mnf %JarName% *.class Icons\*.png ButtonImages\*.png *.properties
     
    @REM Now pick up the Tools it needs:
     
    cd %DEV_HOME%\JavaDevelopment\
    jar -uf %JarName%   NormsTools\Bitmap*.class NormsTools\FindOurHome*.class NormsTools\SaveStdOut*.class
    @ECHO   ---- Created: %JarName% ----
    MORE

    Ok, I will run the jar command. I was running the javac command on my java files to create the class files, but I can just use the ones that eclipse generated. I need to package the client and packet packages, as well as the external jar. I will report back with my attempt.

    --- Update ---

    It indeed did work. I was able to make the jar with the jar command and putting in the packages and the jar file together into the same file. It doesn't throw the error anymore. I also exported it as a runnable jar, and it worked. Thank you
