使用eclipse 开发 j2ee应用的教程

au.com.tusc.session.StoreAccess. </B></P>
<P><B>This will generate required methods for you in your SessionCMPClient class 
and you only have to invoke loginUser, getCustomerData, getManagerData (Manager 
Bean was developed as part of an exercise in the previous chapter) and 
getOutOfStockItems as shown below.</B></P>
<P><B>Now, the last step is to write the code for your client.</B></P>
<P><B>In order to access out of stock items we need an Iterator and an ArrayList 
for items. So, declare two variables of these respective types, and import the 
packages for these types (which are java.util.ArrayList and java.util.Iterator).

<P>Now, here is an exercise for you. In order to proceed further, implement 
Supplier as a CMP Entity Bean. The tasks are given below:</P>

  package au.com.tusc.cmp. </FONT></P>

  signature is find&lt;cmp attribute&gt; instead of findByPrimaryKey, because
