how to access data directly in webapplication?

[ma qiang <ma...@gmail.com>]

Hi all,
    I have developed a web application using Tomcat. In my app, a
client submit a request, and the server read data from HBase then
return these data as a response. But now I can only use shell and
eclipse plugin to invoke program on Hadoop. Who can tell me how to
access data in Hbase directly in java program such as sevlet when
tomcat process a request from client?
     Thank you very much!
