@autowired @qualifier("registerbean") public void setregisterbean(registerbean registerbean) { this.registerbean = registerbean; } i have followed below mentioned steps not solution. 1.added cglib-nodep-2.2.3.jar .it didn't solve issue. 2.found spring has org.springsource.net.sf.cglib contains enhancer class dont know why not taking that.
