How to set a tabbarcontroller as rootview controller of UISplitViewController

When I try to do this, 8 tabitems are displaying without "More" button. so its overlapping items title. And it will display More button if more than 8 tab items.
As it is using width 320, How to set only 5 tabs visible at a time.


I have posted this question in stackoverflaw.com http://stackoverflow.com/questions/4459634/how-to-set-a-tabbarcontroller-as-rootview-controller-of-uisplitviewcontroller

its still an open question. So I think its better to use tabbar instead of tabbarcontroller. But this will change my whole design. :(

How to change Tomcat default character encoding

We faced an issue last week on linux machine,

In a tomcat deployed server, The non-english characters getting from web services are not displaying correctly.

We write a main program in java and retrieved the data through web-service. its parsed well and correctly displayed the non-english character.

So the issue is with tomcat, after investigation we found this.

In the catalina.bat (catalina.sh) add the java args...

set JAVA_OPTS=-Djavax.servlet.request.encoding=UTF-8 -Dfile.encoding=UTF-8

then all encodings seem to come across as UTF-8 by default.. 

This resolved the problem.

Configuring Tomcat's URI encoding

By default, Tomcat uses ISO-8859-1 character encoding when decoding URLs received from a browser. This can cause problems when Confluence's encoding is UTF-8, and you are using international characters in attachment or page names.

1. Edit conf/server.xml and find the line where the Coyote HTTP Connector is defined. It will look something like this, possibly with more parameters:

   <Connector port="8080"/>

2. Add a URIEncoding="UTF-8" property to the connector:

   <Connector port="8080" URIEncoding="UTF-8"/>

3. Restart Tomcat
