HTMLLayout enhancement

Thu, 06 Nov 2003 21:25:25 -0800

I’m posting this in the hopes that someone will find this useful and possibly get checked in.  It was necessary for me to change the some of the colors of the HTMLLayout class.  Instead of keeping them hard-coded, I made some of them configurable as in PatternLayout.  Here are the diffs:

>     Background color of the title bar of the table.

>   */

>   private String tableTitleBarColor = "#336699";

>

>   /**

>     Background color of the row beneath the title bar.

>   */

>   private String tableTitleColor = "#FFFFFF";

>

>   /**

>     Background of the color of the error displayed.

>   */

>   private String tableErrorContentsColor = "#993300";

>

>   /**

>     Font color of the error being displayed.

>   */

>   private String tableErrorFontColor = "White";

>

>   /**

>     Font size of the error being displayed.

>   */

>   private String tableErrorFontSize = "xx-small";

>

>   /**

113a141,216

>   void setTableTitleColor(String tableTitleColor) {

>     this.tableTitleColor = tableTitleColor;

>   }

Here is a snippet of a working log4j.xml:

 

        <appender name="mail" class="org.apache.log4j.net.SMTPAppender">

                <param name="Threshold" value="ERROR"/>

                <param name="BufferSize" value="1"/>

                <param name="From" value="[EMAIL PROTECTED]"/>

                <param name="SMTPHost" value="mesgterm.dr.avaya.com"/>

                <param name="Subject" value="Tomcat Error Notification"/>

                <param name="To" value="[EMAIL PROTECTED]"/>

                <layout class="org.apache.log4j.HTMLLayout">

                     <param name="TableTitleColor" value="#336699"/>

                     <param name="TableTitleColor" value="#FFFFFF"/>

                     <param name="TableErrorContentsColor" value="#FFFFFF"/>

                     <param name="TableErrorFontColor" value="Black"/>

                     <param name="TableErrorFontSize" value="x-small"/>

                </layout>

        </appender>

 

All the above values have default values, so that:

 

<layout class="org.apache.log4j.HTMLLayout"/>

 

will also work.

 

I’d be happy to pass along the source.
