    Well the error seems to indicate that your java file is not named correctly. The other two is just warnings because you are using classes that might be removed in later versions of java.

    If you want to remove the warning, find another class to use.

    Try using a search for base64 to find out about it.

    Perhaps you can find a free class that will do Base64 coding.
