    The first command (Install for load) failed with status 6985 (conditions of use not satisfied)
    Did you check if your application is only importing packages that are available on the target platform you're trying to load into?

    Java Card is a software technology that allows Java-based applications to run securely on smart cards and similar small memory footprint devices. Java Card is a Java platforms targeted for embedded devices. 

    The send command for Java Card applet call by sendBytes() method to send out data. If the data is in an internal buffer, the applet invokes the sendByteLong() command.
