To learn more about WSDL, visit our WSDL Tutorial. WSDL is pronounced as 'wiz-dull' and spelled out as 'W-S-D-L'. WSDL is an integral part of UDDI, an XML-based worldwide business registry. WSDL is a language for describing how to interface with XML-based services. WSDL definition describes how to access a web service and what operations it will perform. WSDL is the standard format for describing a web service. WSDL is an XML based protocol for information exchange in decentralized and distributed environments. WSDL was developed jointly by Microsoft and IBM. WSDL stands for Web Services Description Language. WSDL is an XML-based language for describing web services and how to access them. To learn more about SOAP, visit our SOAP Tutorial. SOAP will be developed as a W3C standard. SOAP is designed to communicate via Internet. SOAP is for communication between applications. SOAP is an XML-based protocol for exchanging information between computers. To learn more about XML-RPC, visit our XML-RPC Tutorial. XML-RPC is the easiest way to get started with web services. XML-RPC allows diverse applications to communicate.Ī Java client can speak XML-RPC to a Perl server. XML responses are embedded in the body of the HTTP response. Requests are encoded in XML and sent via HTTP POST. XML-RPC is a simple protocol that uses XML messages to perform RPCs. This is the simplest XML-based protocol for exchanging information between computers. Complex to understand and develop ejb applications.Over the past few years, three primary technologies have emerged as worldwide standards that make up the core of today's web services technology.For other language client, you need to go for webservice. So EJB with web service will be better option. net, php etc, we need to go with webservices (SOAP or REST). If bean client need to be written in other language such as. In EJB, bean component and bean client both must be written in java language. RMI is built on the top of socket programming.ĮJB technology is built on the top of RMI. It is not required to be deployed on the server.ĮJB is a server-side component, it is required to be deployed on the server. In EJB, middleware services are provided by EJB Container automatically. In RMI, middleware services such as security, transaction management, object pooling etc. The differences between RMI and EJB are given below: RMI Difference between RMI and EJBīoth RMI and EJB, provides services to access an object running in another JVM (known as remote object) from another JVM. Now, it is replaced with JPA (Java Persistent API). It encapsulates the state that can be persisted in the database. Like Session Bean, it contains the business logic but it is invoked by passing message. Session bean contains business logic that can be invoked by local, remote or webservice client. There are 3 types of enterprise bean in java. EJB application is separated from presentation and persistent layer.
