The default look and feel of arrows of rich:inputNumberSlider in RichFaces is not very great (May be they did it intentionally for the users to customize it).

The following CSS styles have to be overridden.

rich-inslider-inc-horizontal, rich-inslider-inc-horizontal-selected

rich-inslider-dec-horizontal, rich-inslider-dec-horizontal-selected

rich-inslider-handler, rich-inslider-handler-selected

As an example, I have provided my styles below.

.rich-inslider-inc-horizontal,.rich-inslider-inc-horizontal-selected {
 background-image:url("/img/rightarrow.png");
}

.rich-inslider-dec-horizontal,.rich-inslider-dec-horizontal-selected{
 background-image:url("/img/leftarrow.png");
}

.rich-inslider-handler,.rich-inslider-handler-selected{
 background-image:url("/img/sliderpos.png");
 width:16px;
 height:16px;
}

I had Ubuntu 9.10 and upgraded to 10.4. The transition was almost smooth other than the following.

• NetBeans failed to start because only openjdk’s JRE was available and the JDK could not be found. So used the command sudo apt-get install openjdk-6-jdk to install openjdk’s JDK

My friend was using Tomcat and MySQL database. He had configured a datasource and as his web application was relatively new, users to his website were very less. As a result the connections were timed out after the default timeout period and exceptions were thrown.

One of the solution to avoid this scenario is to add attributes to validate the connection when borrowing.

<Context path="" reloadable="false" docBase="/home/pathtoapp">
 <Resource name="jdbc/TestDB" auth="Container" type="javax.sql.DataSource"
 maxActive="30" maxIdle="10" maxWait="4000"
 username="username" password="password" driverClassName="com.mysql.jdbc.Driver"
 url="jdbc:mysql://localhost:portnum/dbname" validationQuery="SELECT 1" testOnBorrow="true" />
 </Context>
