works fine now:
@Resource
private javax.ejb.SessionContext sessionContext;
// here i can remove interceptor now :)
public void create(String name, String value, Company company, boolean visible, boolean readonly) {
Parameter p = new Parameter(name, value, company, visible, readonly);
// call Proxy here to raise interception
ParameterServiceLocal ps = this.sessionContext.getBusinessObject(ParameterServiceLocal.class);
ps.create(p);
}
thank you!
