<h1>Validate the deployment artifacts</h1>
<p>The deployment tool starts the deployment process by examining the deployable artifact and determining which modules are Web services enabled by looking for a webservices.xml deployment descriptor file contained within the module. Deployment of services occurs before resolution of service references. This is done to allow deployment to update the WSDL port addresses before the service references to them are processed.</p>
<p>Validation of the artifact packaging is performed to ensure that:</p>
<ul>
<li>Every port in every WSDL defined in the Web services deployment descriptor has a corresponding port-component element.</li>
<li>If the Service Implementation Bean is an EJB, the transaction attributes for the methods defined by the SEI do not include Mandatory.</li>
<li>JAX-RPC service components are only packaged within a WAR file.</li>
<li>Stateless session bean Web services are only packaged within an EJB-JAR file.</li>
<li>The WSDL bindings used by the WSDL ports are supported by the Web Services for J2EE runtime. Bindings that are not supported may be declared within the WSDL if no port uses them.</li>
</ul>

<h1>Server side Implementation</h1>
<p>The Server side implementation is based on generating EJB/Java class that is realized by the Service implementation Bean. Then a web service is generated to receive the SOAP request and sending the request to the EJB/Java Class. The EWS is a tool which will accept a WAR/JAR/EAR file as given by the Usage Scenario�s documentation and generated above explained Web Service and EJB.<p>
<p>Two cases are explaied below</p>
<h2>JAR/WAR file, Java Class based implementation</h2>
<ol>
<li>parse the webservice.xml file</li>
<li>if wsdl file and jaxrpc mapping file does not exsits create them using the SEI</li>
<li>generate axis skelton for axis using the "wsdl file"</li>
<li>generate the wrapper webservice file</li>
<li>generate the one jar file which has all information to deploy the service.
(this is not done yet)</li>
</ol>
<h2>JAR/EAR file,EJB based implementation</h2>
<ol>
<li>parse the webservice.xml file</li>
<li>if wsdl file and jaxrpc mapping file does not exsits create them using the SEI</li>
<li>generate axis skelton for axis using the "wsdl file"</li>
<li>generate ejb remote/local and home interface files.</li>
<li>generate the wrapper webservice file</li>
<li>generate the container DD if required</li>
<li>if the ejb-jar.xml file has security entry add security handler to axis wsdd file </li>
<li>generate the one jar file which has all information to deploy the service.</li>
</ol>
<p>This is how it looks like when the Wraper Web service is generated and deployed in the JAX-RPC runtime</p>
<h2>Architecture Diagram</h2>
<img src="../images/server.gif"/>
<br>
<h2>Sequance Diagram</h2>
<ol>
<img src="../images/seq.png"/>
<li>The WS client will send the SOAP request to axis.</li>
<li>Axis will parse the SOAP request.</li>
<li>Axis will call the request message handlers associated with the web service. (they will take care of the security and transaction mapping of the WS).</li>
<li>Axis will create the wrapper ws instance. (At this point the axis will call the Geronimo and get a reference to the serviceImplBean of ejb. This may be serviceImplBean itself or a indirect reference.) This will most likely to be taken from a Bean pool.</li>
<li>When the webserive method is called in the wrapper Ws the corresponding method in the reference to the service Impl bean will be called.</li>
<li>If result exists it will be given to the axis.</li>
<li>Axis will call the response handlers associated with the WS.</li>
<li>The result is marshaled and sent to the Client as SOAP.</li>
</ol>
<h2>Class Diagram</h2>
<img src="../images/class.png"/>
<p>The tool will generate dummy Remote(Local) interface and dummy Home(LocalHome) interface.
they are for deploy the ejb in the continer and is transparet from the deployer ews user.</p>
<p>There are three ways the Web Service can accsess the ejb.</p>
<ol>

<h1>Convert the Web services into standard J2EE artifacts</h1>
<h2>Web component</h2>
<p>If the implementation is a JAX-RPC Service Endpoint, a servlet is generated to handle parsing the incoming SOAP request and dispatch it to an instance of the JAX-RPC service component. The generated servlet class is dependent on threading model of the JAX-RPC Service Endpoint. The web.xml deployment descriptor is updated to replace the JAX-RPC Service Endpoint class with the generated servlet class. If the JAX-RPC
Service Endpoint was specified without a corresponding servlet-mapping, the deployment tool generates one. The WSDL port address for the Port component is the combination of the web app context-root and servlet url-pattern.</p>
<h2>Stateless Bean Component</h2>
<p>If the implementation is a stateless session bean, the deployment tool has a variety of options available to it. In general, the deployment tool generates a servlet to handle parsing the incoming SOAP request; the servlet obtains a reference to an instance of an appropriate EJBObject and dispatches the request to the stateless session EJB. How the request is dispatched to the Service Implementation Bean is dependent on the deployment tool and deploys time binding information supplied by the deployer.</p>
