Migrating from jboss 4.2.3 to jboss 5.1.0 getting spring related errors -

getting below error while migrating through jboss 4.2.3 jboss 5.1.0. jboss 5.1.0 not able load spring configuration files. additionally have removed below errors creating object explicitly using new keyword in java class instead of using spring dependency injection “viewchactionhelper'”.

and able resolve errors getting @ time of server startup. able see login page when click on login button calls action i.e. loginaction in creating object of service class through setter getter dependency injection in case throwing nullpointerexception.

i believe there problem in loading spring configurations.

any appreciated.
