一连好久用Jbuilder搞实体Bean ，，，数据库是用Mysql ，，或Jbuilder中的JDatastore,, 老是出现错！，，真是郁闷！！！！
出错提示:
"mysqlCMP.ejbgrpx": ERROR: Error from ejbc: Error while reading 'META-INF/weblogic-cmp-rdbms-jar.xml'. The error was:
"mysqlCMP.ejbgrpx": weblogic.ejb20.cmp.rdbms.finders.IllegalExpressionException:

到底怎么回事? 第一行中怎么说是读'META-INF/weblogic-cmp-rdbms-jar.xml'出错，，，但我看了，，也没有什么错呀！！！，奇怪，，
反正就是错在EJB-QL语句中了，，但是EJB-QL语句（在findByFrimaryKey中）是Jbuilder自动生成的呀！
