Error opening socket

[Alexandre Gomes <al...@gmail.com>]

I'm trying to use Derby with a web application running on Tomcat. The
Tomcat process is running as root user. I'm using the derbyclient.jar
driver. What should be the cause of my problem?

Exception: org.apache.derby.client.am.DisconnectException:
java.security.PrivilegedActionException : Error opening socket to
server localhost on port 1527 with message : nullError Code: -4499

thank you,
Alexandre

Hi Alexandre -
There may be other causes of this but this is the message when the 
client attempts to connect but the Network Server has not been started.  
Can you ping the Network Server?  Do the messages in the console window 
show that it has started properly?

I am just now working on this bug so that the underlying error can be 
revealed :(  It is not actually a security exception; it is that an 
exception was encountered when running in a privileged block.  The 
underlying exception's message is "null" but we can't tell (until I fix 
this bug) what the underlying exception class is.

Are you sure that you are running a network server on port 1527?
