<prereq><p>Before you can create an enterprise bean, you must:</p><ul> | |
<li>Define an EJB project to contain the enterprise bean. See <xref href="tecrtpro.dita"></xref>.</li> | |
<li>Install XDoclet annotation support and enable it. See <xref href="txdocletconf.dita"></xref>.</li> | |
</ul></prereq> | |
<context><p>To create a message-driven bean, complete the following steps:</p></context> | |
<steps> | |
<step><cmd>In the <tm tmclass="special" tmowner="Sun Microsystems, Inc." tmtype="tm" | |
trademark="Java">Java</tm> EE perspective, click <menucascade><uicontrol>File</uicontrol> | |
<uicontrol>New</uicontrol><uicontrol>Other</uicontrol></menucascade>. Select <menucascade> | |
<uicontrol>EJB</uicontrol><uicontrol>XDoclet Enterprise JavaBean</uicontrol> | |
</menucascade> and click <uicontrol>Next</uicontrol>.</cmd></step> | |
<step><cmd>Select the <uicontrol>Message Driven Bean</uicontrol> and click <uicontrol>Next</uicontrol>.</cmd> | |
</step> | |
<step><cmd>Select the <uicontrol>Project</uicontrol> that will contain the | |
new bean. </cmd></step> | |
<step><cmd>In the <uicontrol>Folder</uicontrol> field, select the folder for | |
the new bean. </cmd></step> | |
<step><cmd>In the <uicontrol>Java package</uicontrol> field, enter the package | |
name for the new bean. </cmd></step> | |
<step><cmd>In the <uicontrol>Class name</uicontrol> field, type a name for | |
the enterprise bean. By convention, bean names should begin with an uppercase | |
letter. </cmd><info><note>You can use Unicode characters for the bean name, | |
but Unicode characters are not supported for enterprise bean packages and | |
classes associated with enterprise beans.</note></info></step> | |
<step><cmd>Change the <uicontrol>Superclass</uicontrol> for the bean if you | |
want it to inherit from a class other than <codeph>java.lang.Object</codeph> and | |
click <uicontrol>Next</uicontrol>.</cmd></step> | |
<step><cmd>Provide an <uicontrol>EJB Name</uicontrol> for the bean. This is | |
the name of the enterprise bean class. </cmd></step> | |
<step><cmd>Provide an <uicontrol>Destination JNDI Name</uicontrol> for the | |
bean. This is a logical name used by the server to locate an enterprise bean | |
at runtime. </cmd></step> | |
<step><cmd>Provide an <uicontrol>Display Name</uicontrol> for the bean. This | |
is a short name for the enterprise bean that is used by tools. </cmd></step> | |
<step><cmd>Provide a text <uicontrol>Description</uicontrol> for the bean.</cmd> | |
</step> | |
<step><cmd>Select a <uicontrol>Destination</uicontrol> for the new bean: </cmd> | |
<info><ul> | |
<li><uicontrol>Queue</uicontrol> specifies that the point-to-point JMS messaging | |
model will be used. </li> | |
<li><uicontrol>Topic</uicontrol> specifies that the publish-and-subscribe | |
JMS messaging model will be used.</li> | |
</ul></info></step> | |
<step><cmd>Select a <uicontrol>Transaction Type</uicontrol> for the new bean:</cmd> | |
<info><ul> | |
<li><uicontrol>Container</uicontrol> specifies that the transaction demarcation | |
is performed by the container.</li> | |
<li><uicontrol>Bean</uicontrol> specifies that the transaction demarcation | |
is performed by the bean. </li> | |
</ul>Click <uicontrol>Next</uicontrol>.</info></step> | |
<step><cmd>Select the type of <uicontrol>Modifiers</uicontrol> to use for | |
the class.</cmd></step> | |
<step importance="optional"><cmd>Select the <uicontrol>Interfaces</uicontrol> you | |
want the bean to implement. Click <uicontrol>Add</uicontrol> to select interfaces | |
that you want to implement and click <uicontrol>Remove</uicontrol> to take | |
away interfaces that you no longer want to implement.</cmd></step> | |
<step><cmd>Select the method stubs that you want the wizard to create.</cmd> | |
</step> | |
<step><cmd>Click <uicontrol>Finish</uicontrol> to add the new bean to the | |
specified EJB project.</cmd></step> | |
