Open up Applications->Accessories->Passwords and Encryption Keys
Right click Passwords:login and unlock it.
You should be able to expand the tree and find a listing for vino. Right click and delete it.
Close Passwords and Encryption Keys.
Open gconf-editor as and navigate to /desktop/gnome/remote_access
Enter in your BASE64 encoded password into the vnc_password key.
Save the config and close the editor.
Reboot and you can now use your VNC client to connect to your machine without being first prompted with the keyring.

Enable apache public_html in 9.10

sudo a2enmod userdir

Moreover, need to chmod the user dir to be 755.

Ubuntu 9.10 server installed

Just new-installed the Ubuntu 9.10 in T43, for server usage testing.

The booting time is damn short.

Ubuntu-tomcat-GWT

近來在試 Google Web Toolkit (GWT)，為了這個要裝 Tomcat 。數天前說過，Ubuntu 可以 apt-get Tomcat 。但後來發現，那個 Tomcat 跑不到 GWT Sample 的 war 。

後來，到 Apache 官網下載 Tomcat 去跑，跑 war 卻 ok 。

tomcat

起初，我還以為 tomcat 是需要 Apache 才能跑。原來這兩個東東可以是完全沒有關係。

Ubuntu apt-get 提供了 tomcat 。但奇怪的是， Ubuntu 的 wiki page 卻叫你去官網下載。另外， Ubuntu tomcat 在安裝時，會告訴你依靠 gcj ，這點也叫人不安。

不過，其實使用 Ubuntu-tomcat ，其實不是想像中那麼可怕。

要注意的是，只要修改 xml 檔，就能使 tomcat 使用 sun-java 。
