<li>Access an existing Java bean Web archive (WAR) file that you want to use as a Web service. A Java bean in a Web container requires the following:
|
||
|
|
<ul>
|
||
|
|
<li>It must have a public default constructor.</li>
|
||
|
|
<li>It must have exposed public methods.</li>
|
||
|
|
<li>It must not save a client-specific state between method calls.</li>
|
||
|
|
<li>It must be a public, non-final, and non-abstract class.</li>
|
||
|
|
<li>It must not define a finalize() method.</li>
|
||
|
|
</ul></li>
