hi rajan,
check out ur xml-descriptor file...when u have have cmp there is no need of
findByPrimaryKey method in bean but in case u have BMP it is
required...check out if ur three xml-descriptor files are similar to the
descriptor giben in examples of enity bean provided with weblogic(hope u r
using Weblogic).
