Trouble makeing all included jars work properly

I am trying to make a JAX-RPC client application GUI deploy over web start. If the program does not attempt to make the connection then the client works. When the client tries to connect I get this error:

access denied (java.util.PropertyPermission com.sun.xml.rpc.client.ContentNegotiation read)

I don't know what it means or how to fix this error. Any help would be appreciated.

I needed to add in the lines <security><all-permissions/></security>into each jnlp file so all of the jars could have complete access to the client machine
