<h1>New Features</h1>
<p><a name="OpenEJB1.0Beta1-EJB2.0Localinterfacesupport"></a></p>
<h2>EJB 2.0 Local interface support</h2>
<p>OpenEJB now has support for EJB 2.0 Local Interfaces. This is very nice
for when OpenEJB is combined with Tomcat or embedded in another
application where Remote interfaces are not always needed. See the
"Moviefun" example in the source or binary distributions for how to use
them. Note that no other EJB 2.0 features (such as CMP 2 or MDBs)
are supported in the OpenEJB 1.x codebase.</p>
<p><a name="OpenEJB1.0Beta1-CollapsedEARsupport"></a></p>
<h2>Collapsed EAR support</h2>
<p><a href="collapsed-ear.html">Collapsed EAR</a>
s are an OpenEJB invention allowing you to combine your ejbs and servlets
in the same archive and classloader. This is essentially a new way to
embed OpenEJB into Tomcat so that OpenEJB and your EJBs are loaded only
into your webapp. Combine this with an embedded database and you have a
complete mini-J2EE environment that can be hosted in your Tomcat webapp
space.</p>
<p>See the "Moviefun" example in the distribution which will be online for
a short while here:</p>
<p><a href="http://demo1.openejb.org/moviefun">http://demo1.openejb.org/moviefun</a></p>
<p>(visit <a href="http://demo1.openejb.org/moviefun/setup.jsp">http://demo1.openejb.org/moviefun/setup.jsp</a>
to reset)</p>
<p><a name="OpenEJB1.0Beta1-UnpackedEJBJarsupport"></a></p>
<h2>Unpacked EJB Jar support</h2>
<p>It is now possible to deploy and run EJB apps that are not in a *.jar
archive. For example, for ejb app located at:</p>
<pre><code>/home/jsmith/myejbapp/META-INF/ejb-jar.xml
</code></pre>
<p>Simply add a Deployments declaration to the openejb.conf like the
following:</p>
<pre><code>&lt;Deployment dir="/home/jsmith/myejbapp" /&gt;
</code></pre>
<p><a name="OpenEJB1.0Beta1-AutoDeployforSimpleApps"></a></p>
<h2>Auto Deploy for Simple Apps</h2>
<p>In OpenEJB 1.0 beta1, the use of openejb-jar.xml is not required for
ejb-jar.xml files that do not contain CMP EntityBeans or ejbs with
multiple datasource references.</p>
<p><a name="OpenEJB1.0Beta1-MacOSXUsers"></a></p>
<h2>Mac OSX Users</h2>
<p>The speed of the Remote Server has been improved tremendously to
compensate for differing default parameters for TCP Socket creation and
closing in the Mac OSX Java VM. This makes sequential calls from a Remote
Client to the Server several times faster.</p>
<p><a name="OpenEJB1.0Beta1-UpgradeNotes"></a></p>
<h1>Upgrade Notes</h1>
<p><a name="OpenEJB1.0Beta1-CMPconfigchange"></a></p>
<h2>CMP config change</h2>
<p>In 0.9.2 and before, the JDO database was using the private JNDI namespace
of the very first CMP accessed to grab a datasource and hold onto it for
use on all requests into the CMP container. This was configured with
something like this:</p>
<pre><code>&lt;database name="Global_TX_Database" engine="instantdb"&gt;
&lt;jndi name="java:comp/env/jdbc/basic/entityDatabase" /&gt;
&lt;mapping href="conf/default.cmp_mapping.xml" /&gt;
&lt;/database&gt;
</code></pre>
<p>This was just wrong. We've switched it so that the "jndi" tag of a Castor
database.xml file can be set directly to the global JNDI name of a
Connector element declared in an openejb.conf file. </p>
<pre><code> &lt;database name="Global_TX_Database" engine="instantdb"&gt;
&lt;jndi name="java:openejb/connector/Default JDBC Database" /&gt;
&lt;mapping href="conf/default.cmp_mapping.xml" /&gt;
&lt;/database&gt;
</code></pre>
<p>This is still not so optimal as we do not want to people using OpenEJB's
internal jndi and encourage people to become dependent on it. Newer
releases of Castor allow for a completely programmatic way to configure a
JDO database. In future releases, these global and local database files
will go away all together! You will only need to specify your mapping.xml
and will be able to pack it in your ejb jar.</p>
<p><a name="OpenEJB1.0Beta1-ClassLoaderchange"></a></p>
<h2>ClassLoader change</h2>
<p>In 0.9.2 all EJBs were added to the same classloader as the Containers,
Server and all the other EJBs. In 1.0 beta1, all the EJBs are still in the
same classloader, but one that is a child of the Container and Server.
The code to keep each EJB jar in it's own classloader does exist, but
limitations in the way we configure the CMP container with Castor prevent
us from using it. When the CMP change made above is fixed, we will support
separate classloaders for each EJB jar as an option.</p>
