I install the petstore step by step according the installation instruction. Everything is OK before the last step. When I deploy the application, there has problem during the process.
...
Compling RMI-IIOP code...
Making client JARs...
Making server JARS...

Then the error occured. The information is:
There was a deployment error.java.rmi.ServerException:RemoteException occured in server thread; nested exception is:
java.rmi.RemoteException:Error while loading JAR D:\j2sdkee1.2.1\repository\java\application\peststore982722929617Server.jar
javax.naming.invalidNameException:JNDI name 'jdbc/EstoreDB' for resource reference 'jdbc/EstoreDataSource' is not valid

Thanks for reply
