<h1>Configuration</h1><p>In order to use the same database in Java and .NET
application you will need to configure
<a href="../../implementation_strategies/aliases.html" class="wikiLink">Aliases</a>. This is necessary due to the
<a href="../../object_lifecycle/class_name_format_in_.net.html" class="wikiLink">difference in Java and .NET</a>
class name format (it can be also helpful if you do not want to give the same
names to the classes in different applications).</p>
<p>First of all you will need to alias the database itself:</p>
<span name="cs_wiki_filter" csw_filters="cs"><p>c#: </p>
<p><code>IConfiguration configuration =
Db4oFactory.NewConfiguration();</code></p>
<p><code>configuration.AddAlias(new TypeAlias("com.db4o.ext.Db4oDatabase","Db4objects.Db4o.Ext.Db4oDatabase,
Db4objects.Db4o"));</code></p>
</span>
<span name="cs_wiki_filter" csw_filters="vb"><p>VB: </p>
<p><code>Dim configuration As IConfiguration =
Db4oFactory.NewConfiguration()</code></p>
<p><code>configuration.AddAlias(new TypeAlias("com.db4o.ext.Db4oDatabase","Db4objects.Db4o.Ext.Db4oDatabase,
Db4objects.Db4o"));</code></p>
</span>
<p>Then you will need to alias the persisted classes. If your
class names match in Java and .NET, you can use a <a href="../../implementation_strategies/aliases/wildcardalias.html" class="wikiLink">WildcardAlias</a>,
which allows to alias all the classes in a package/namespace at once:</p>
<span name="cs_wiki_filter" csw_filters="cs"><p>c#: </p>
<p><code>configuration.AddAlias(new WildcardAlias(" com.db4odoc.aliases.*","
Db4objects.Db4odoc.Aliases.*, Db4objects.Db4odoc "));</code></p>
</span>
<span name="cs_wiki_filter" csw_filters="vb"><p>VB: </p>
<p><code>configuration.AddAlias(new WildcardAlias(" com.db4odoc.aliases.*","
Db4objects.Db4odoc.Aliases.*, Db4objects.Db4odoc "));</code></p>
</span>
<p>If you want to alias only specific classes you can use
<a href="../../implementation_strategies/aliases/typealias.html" class="wikiLink">TypeAlias</a>.</p>
<span name="cs_wiki_filter" csw_filters="cs"><p>c#: </p>
<p><code>configuration.AddAlias(new TypeAlias(" com.db4odoc.aliases.Pilot","
Db4objects.Db4odoc.Aliases.Pilot, Db4objects.Db4odoc "));</code></p>
</span>
<span name="cs_wiki_filter" csw_filters="vb"><p>VB: </p>
<p><code>configuration.AddAlias(new TypeAlias(" com.db4odoc.aliases.Pilot","
Db4objects.Db4odoc.Aliases.Pilot, Db4objects.Db4odoc "));</code></p>
</span>Remember that the configuration should be created and
supplied to the object container on opening.
