how to increase the length of the read user memory bank

Hi everyone,
In the project, I use FX9600 and Fx7500 devices. I use:
Zebra-FXSeries-Embedded-SDK-Java-Windows_V1.0.0 and API3 libraries.
In my code to read the user's memory bank, I use the following method: .getTag (). GetMemoryBankData (). Currently, the maximum length I can read is 128 bits. How could I increase this value to memory bank tags that have 512 bits or more?
Thanks for any tips :)

Java not found error occurred while running java application in FX9600 reader


I am trying to run a java application (.jar file) in FX9600 RFID Reader through telnet but I am getting error as "java not found".
But, as far as my knowledge, FX9600 reader comes with java pre-installed.
Java was working in RFID reader 2-3 before.

Please if somebody already faced this issue, I would greatly appreciate the help!.
