Jar working jnlp not working

I have created a java SE application that uses the mysql database using mysql java connector.I have hosted the apache and mysql server on ubuntu.

I have my .jar file on the apache server and also the jnlp,

When I simply download the jar file and run it, it seems to work, but, when I am trying to use it through jnlp the first view comes up then when I enter my username and password and click the login button it just stops there

Here is my JNLP file

Please let me know what it the error. On the server I have 80 8080 and 3306 ports as public ports. I am not the root user though.

as I said I can update the database using the jarfile that I downloaded from the server but when I try to run the file through JNLP I freezes.

I saw the exception in java console it says

Exception in thread "AWT-EventQueue-0" java.lang.ExceptionInInitializerError at com.mysql.jdbc.NonRegisteringDriver.connect( at java.sql.DriverManager.getConnection(Unknown Source) at java.sql.DriverManager.getConnection(Unknown Source) at MyProject.database.connect(

Caused by: access denied ("java.util.PropertyPermission" "file.encoding" "read")
at Source)

I cant figure out what the problem is? do I need some port open for JNLP or anything.

Any help appreciated.

I would be looking into the access denied error, but as I have never used JNLP (only just found out what it stands for) I can't be anymore help.
