Error deploying EAR that is a Webservice

Question

In the SAP NetWeaver Developer Studio, when I select the option "Deploy to J2EE engine" on my EAR file, I get the following error:
                     java.rmi.RemoteException: Cannot deploy application sap.com/LDAPManagerEAR..
                     Reason: Incorrect application sap.com/LDAPManagerEAR:
                     Bean EB_bindBean: Remote home interface com.upc.ldap.ejb.EB_bindHome must be a valid RMI-IIOP remote interface.
                     Bean EB_bindBean: the return type for a create<METHOD> method of the session bean local home interface must be the session bean local interface type. EJB specification 7.10.8.
                     Error in the remote interface com.upc.ldap.ejb.EB_bind of bean EB_bindBean: No corresponding business method in the bean class com.upc.ldap.ejb.EB_bindBean was found for method bindLDAP.
                     Error in the local interface com.upc.ldap.ejb.EB_bindLocal of bean EB_bindBean: No corresponding business method in the bean class was found for method bindLDAP.; nested exception is:
                          com.sap.engine.services.deploy.container.DeploymentException: <--Localization failed: ResourceBundle='com.sap.engine.services.deploy.DeployResourceBundle', ID='com.sap.engine.services.ejb.exceptions.deployment.EJBDeploymentException: Incorrect application sap.com/LDAPManagerEAR:
Anybody can help me ? Thanks

I?ve seen the code.
You need to synchronize the interfaces and the business method. For instance, on the interface you have declared:
public String bindLDAP(String username, String password)throws RemoteException;
And then you attempt to implement:
public String bindLDAP(String username, String password) throws NamingException
Therefore the error:
Error in the remote interface com.upc.ldap.ejb.EB_bind of bean EB_bindBean: No corresponding business method in the bean class com.upc.ldap.ejb.EB_bindBean was found for method bindLDAP.
Also, you must be consisten with local-remote-home interfaces. You've declared the EB_bindLocalHome as LocalHome, but don't use it as return parameter on the EB_bindHome interface. Try the following:
package com.upc.ldap.ejb;
import javax.ejb.EJBHome;
import java.rmi.RemoteException;
import javax.ejb.CreateException;
public interface EB_bindHome extends EJBHome {
      * Create Method.
     public  EB_bindLocalHome create() throws CreateException;
You might want to use an EJB generator as on SAP Developer Studio to automate all these tasks and avoid revisiting the code.
I hope it helps
