thanks Peter , u r the one who has replied for almost all my questions so far .. :) finally i got the problem solved .. when JBOSS integrates with Netbeans 6.0 , it automatically detects the settings to be conformed with J2EE 1.4 specs.not J2EE 5...so il try with JBOSS 5.0 later.. so i had to edit the configuration files as well , and had to use JNDI as well. but the same application is working in Glassfish server , without the need of any modification of config files , and without using JNDI lookups.. here , iam deploying the application client's jar also to the deploy directory , and after that clicks on RUN in Netbeans , so no classpath is involving here.Im that couldnt i use the @Local interface instead of the @Remote one ? another question , what s the use of @EJB annotations ? are those only for local clients ? won't that be supports for Local clients ? also , what is the use of the local interface (@Local) .. i couldnt find any example code which uses that interface..i tried even to use it..but it failed.so i gave that up..so please , if u have any simple example code which uses the @Local interface please send me ( through this or my mail sajhak(a)hotmail.com ) so that i can get a thorough idea of EJB ..
