i encounter a problem when running client to access
an ejb deployed on jboss3.0.4-tomcat4.1.12. i test the
cmr one to one relationship via xdoclet.1.2-b3.
it issues window application error dialogue: "The
instruction at '0x6d3a1bea' referenced memory at
'0x0000000c'. The memory could not be 'read'." is
there any possible may cause such kind of error, or is
it a bug for java platform. (the sdk i use is version
j2sdk1.4.1_01)?
by the way, i try to run the client code on other
people's jvm, yet it still issues such kind of
problem.
i appricate any suggestions, sincerely.
thank you very mcuh.
client code looks like
