I am new to Java Card Programming (with netbeans). I did everything in the Java Card Development Quick Start page page and I created a classic card applet and tried simulate it. But when I try to simulate and send a command on device console, it sends an error
"Connection refused: connect".
I didn't understand, what is wrong.
any suggestions?
here it's screen shot:

Java Card technology provides an architecture for open application development for smart cards, using the Java programming language. The technology can also be used to develop applications for other devices that have extremely small memory, such as subscriber identity module (SIM) cards for wireless phones.
Java Card technology is used in a wide range of smart card applications, including: Smart ID badges for logical and physical access to enterprise resources. Subscriber Identity Modules used in mobile phones on wireless networks. Machine Identity Modules used in M2M and IoT.
Technical overview of SIM appletsApplets are based on Java Card, a limited subset of Java language. The SIM cards operating system (OS) is similarly written in Java Card. The OS is the first and most important SIM Applet.
Java Card gives the user the ability to program the devices and make them application specific. It is widely used in different markets: wireless telecommunications within SIM cards and embedded SIM, payment within banking cards and NFC mobile payment and for identity cards, healthcare cards, and passports.
