open the /etc/network/interfaces file.
sudo vi /etc/network/interfaces
If you are using DHCP for your primary network card which is usually eth0, you will see the following lines
auto eth0
iface eth0 inet dhcp
As you can see, it’s using DHCP right now. We are going to change dhcp to static, and then there are a number of options that should add and here is the example and you can change these settings according to your network settings.
auto eth0
iface eth0 inet static
address 192.168.1.100
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1
Change DNS server address
sudo vi /etc/resolv.conf
name server 203.192.133.3
Restart the neworking service using the following command
sudo /etc/init.d/networking restart

Install JSDK on Ubuntu 6.0
Now go to Sun's website http://java.sun.com and select the java jdk or jre that you want. In my case I needed 1.4.2 so I downloaded j2sdk-1_4_2_09-linux-i586.bin.
Then run the following commands from the terminal:
First install the required packages:
sudo apt-get install fakeroot java-package java-common
Create the Deb file for the install:
fakeroot make-jpkg jre-1_5_0_05-linux-i586.bin
Install The deb file
sudo dpkg -i sun-j2re1.5_1.5.0+update05_i386.deb
Now make Sun's java the default by running this command and selecting it.
sudo update-alternatives --config java
Then run the following commands from the terminal:

sudo dpkg -i sun-j2re1.5_1.5.0+update05_i386.deb
Now make Sun's java the default by running this command and selecting it.
sudo update-alternatives --config java
hsqldb_stratup_usage
Usage: java org.hsqldb.Server [options]
The server looks for a 'server.properties' file in the current directory and
loads properties from it if it exists.
Here is an example 'server.properties' file:
server.port=1234
#mounts a file-based (persistent) database with alias 'filetest'
#database connection url would be 'jdbc:hsqldb:hsql://host:1234/filetest'
#but '/filetest' can be omitted because database.0 is the default
server.database.0=file:/mydatbasedir/test
server.dbname.0=filetest
#mounts a 'file_in_jar' database with alias 'restest'
#database connection url would be 'jdbc:hsqldb:hsql://host:1234/restest'
server.database.1=res:/mypackage/test
server.dbname.1=restest
#mounts a 100% in-memory (transient) database with alias 'memtest'
#database connection url would be 'jdbc:hsqldb:hsql://host:1234/memtest'
server.database.2=mem:test
server.dbname.2=memtest
...
server.database.n=...
server.dbname.n=...
server.silent=true
#end of 'server.properties' file
Command line options override those loaded from the 'server.properties' file.
The default port is 9001 if tls is false and 544 if it is true.
When omitted, the value of tls is true iff the system property:
javax.net.ssl.keyStore
is defined. An example command line invocation requesting TLS might look like:
java -Djavax.net.ssl.keyStore=x -Djavax.net.ssl.keyStorePassword=y org.hsqldb.Server [options]
HSQLDB server model startup example:
| OPTION | TYPE | DEFAULT | DESCRIPTION |
| -? | -- | -- | prints this message |
| -address | name|number | any | server inet address |
| -port | number | 9001/544 | port at which server listens |
| -database.i | [type]spec | 0=test | name of database i |
| -dbname.i | alias | -- | url alias for database i |
| -silent | true|false | true | false => display all queries |
| -trace | true|false | false | display JDBC trace messages |
| -tls | true|false | false | TLS/SSL (secure) sockets |
| -no_system_exit | true|false | false | do not issue System.exit() |
