[Building Sakai] How to Using POI library in Sakai project?

[baotram]

Hi Adrian!
 three jars file in my local maven repository:
  .m2/repository/poi/poi/3.7-20101029/poi-3.7-20101029.jar
 .m2/repository/poi/poi/ooxml-3.7-20101029/poi-ooxml-3.7-20101029.jar
.m2/repository/poi/poi/scratchpad-3.7-20101029/poi-scratchpad-3.7-20101029.jar

I add dependency in pom.xml  right or wrong??:

<dependency>
      <groupId>poi</groupId>
      <artifactId>poi</artifactId>
        <version>3.7-20101029</version>
</dependency>
 <dependency>
         <groupId>poi</groupId>
         <artifactId>poi</artifactId>
         <version>ooxml-3.7-20101029</version>
 </dependency>
 <dependency>
        <groupId>poi</groupId>
        <artifactId>poi</artifactId>
        <version>scratchpad-3.7-20101029</version>
 </dependency>

Please help me about that error.
Thanks for your helping!
BaoTram.
