4 years ago Hello,
I have cloned the PMQ and unzipped the zip file, opened a terminal window in Ubuntu, just copied and executed javac statement from cmdcompile. You may receive a warning, it is okay, then try the next line (java statement). I did the above steps and it works without using eclipse. If you have eclipse, it could be helpful to open the whole project and trace it step-by-step.
Best, Hassan

Hello， I have read your paper 'Achieving Privacy-Preserving Multi Dot-Product Query in Fog Computing-Enhanced IoT' , and similarly ,I faced a problem when running code PMQGUI.java. I used cmd to compile the code PMQGUI in the way which is included in the cmdcompile.txt. That is 'javac -classpath ".:jpbc-plaf-2.0.0.jar:jpbc-api-2.0.0.jar" PMQGUI.java -Xlint'. But I did not compile successfully. So I choosed a software named eclipse and I have configured JPBC on it. And I put file named '.classpath' and '.project' in my package in eclipse. I could run the code BGN.java successfully but could not run the code PMQGUI.java. The error showed 'java.lang.NullPointerException'. I could not solve it after I tried several methods. So I tried to seek your help again. It will help me a lot if you can give me some help when you are free. Best wishes for you!
