I tried connecting to an embedded server to a location in the
D:\DATABASE\CAD_DB using this policy file
Filename dbViewSecurityPolicy.policy
grant codeBase "file://D:/DEVELOPMENT_ECLIPSE_XITH_LIBRARY/B1711/derby.jar" {
permission java.lang.RuntimePermission "createClassLoader";
permission java.util.PropertyPermission "derby.*", "read";
permission java.io.FilePermission "${CadEngine.system.home}","read";
permission java.io.FilePermission
"${CadEngine.system.home}${/}*","read,write,delete";
permission java.io.FilePermission
"${CadEngine.system.home}${/}CAD_DB${/}-", "read,write,delete";
permission java.util.PropertyPermission "derby.storage.jvmInstanceId","write";
};
grant codeBase "file://D:/DEVELOPMENT_ECLIPSE_XITH_LIBRARY/B1711/derbynet.jar" {
permission java.lang.RuntimePermission "createClassLoader";
permission java.util.PropertyPermission "derby.*", "read";
permission java.io.FilePermission "${CadEngine.system.home}","read";
permission java.io.FilePermission
"${CadEngine.system.home}${/}*","read,write,delete";
permission java.io.FilePermission
"${CadEngine.system.home}${/}CAD_DB${/}-", "read,write,delete";
permission java.util.PropertyPermission "derby.storage.jvmInstanceId","write";
};
protected void waitForStart() throws Exception {
org.apache.derby.drda.NetworkServerControl SERVER = null;
SERVER = new
NetworkServerControl(InetAddress.getByName("localhost"), 1527 );
System.out.println("Testing if Embedded Server is up and
running!");
for (int i = 0; i < 10; i++) {
try {
Thread.currentThread().sleep(5000);
SERVER.ping();
} catch (Exception e) {
System.out.println("Try #" + i + " " +
e.toString());
if (i == 9) {
System.out.println("Giving up trying to
connect to Embedded
Network Server!");
throw e;
}
}
}
System.out.println("Derby Embedded Network Server now running");
}
To execute this
java
-DCadEngine.system.home=D:\Database;-Djava.security.manager=D:\DEVELOPMENT_2010_XITH_2\PROJECT_AREA\ECLIPSE_XITH\gcDbView\src\dbViewSecurityPolicy.policy;
test
But everytime I did this I get the following error

Could somebody point me step by step on how to solve this. Is over 2
weeks I'm stuck on this. The application has also a Connection to a
another embedded database located at D:\DATABASE\SETTINGS. This is
working well.
