Hi Rick, Thank you for the tips. My problem was solved ( I used the fastest solution, -noSecurityManager).
Sadly to say that Netbeans does not allow me to pass arguments for the Database and I have to use the console, and beside this, I used Squirrel to connect at my network server started using the .sh script. I have created a database using ij, but Squirrel ( actually Apache Derby Driver) complained about having an empty password/username ( How can this <https://wso2.org/jira/browse/DS-136> defect be fixed ? ). Thanks again for helping me with this.
