Hello to all, I have been trying to test the new clients. I have downloaded Par's installer for the 2.0.19 but when I try to send a mail I get to the 82% upload then the server and the client take a long pause, then both start to transmit at the same time. They end up by polling and just going back and forth until I abort. Next I tried to run the newer version 2.0.22 and I get this error when I try to start it: glenn@glenn:~$ java -jar jPSKmail-2.0.22.jar Configuration.xml jPSKmail ends here... Exception in thread "main" java.lang.NoClassDefFoundError: gnu/io/SerialPortEventListener at javapskmail.Main.handlegps(Main.java:1932) at javapskmail.Main.main(Main.java:373) Caused by: java.lang.ClassNotFoundException: gnu.io.SerialPortEventListener at java.net.URLClassLoader$1.run(URLClassLoader.java:217) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:205) at java.lang.ClassLoader.loadClass(ClassLoader.java:321) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:294) at java.lang.ClassLoader.loadClass(ClassLoader.java:266) ... 2 more Any help with these matters will be greatly appreciated. Very 73 to all PSKmailers de Glenn WB2LMV
