Your applet needs permission to read properties. You can give it permission by signing the jar file or by making changes to the local JRE's .java.policy file.

Signed the jar ( i get a prompt do i want to trust this program cuz it signiture could not be verified) and still get this

Files on server are read/execute chmod 755 (+write for admin)

I keep the classes on the server in folders - when i try to connect by clicking on a button there is a prompt ( something about that soe components are not signed) if i click yes i get some loading problem (Class.forName Exception) and if i click no then it is loaded but i get an exception about the acces reading. How to add that jar in a good way ? IM tearing my hair out .... I tried adding a lib katalog and copying the jar into it and addigng is as a refference to an internal jar ... But still nothing :/.

For testing you could change the local .java.policy file to give all codebases permission to read properties.
Use the policytool program and make any entry something like this:

permission java.util.PropertyPermission "*", "read";
