| |
| <P>You can configure data sources from within your test case (avoiding the need for an openejb.xml entirely) like so:</P> |
| |
| <DIV class="code panel" style="border-width: 1px;"><DIV class="codeContent panelContent"> |
| <PRE class="code-java"> |
| Properties p = <SPAN class="code-keyword">new</SPAN> Properties(); |
| p.put(Context.INITIAL_CONTEXT_FACTORY, <SPAN class="code-quote">"org.apache.openejb.client.LocalInitialContextFactory"</SPAN>); |
| |
| p.put(<SPAN class="code-quote">"myDataSource"</SPAN>, <SPAN class="code-quote">"<SPAN class="code-keyword">new</SPAN>:<SPAN class="code-comment">//Resource?type=DataSource"</SPAN>); |
| </SPAN>p.put(<SPAN class="code-quote">"myDataSource.JdbcDriver"</SPAN>, <SPAN class="code-quote">"org.apache.derby.jdbc.EmbeddedDriver"</SPAN>); |
| p.put(<SPAN class="code-quote">"myDataSource.JdbcUrl"</SPAN>, <SPAN class="code-quote">"jdbc:derby:derbyDB;create=<SPAN class="code-keyword">true</SPAN>"</SPAN>); |
| p.put(<SPAN class="code-quote">"myDataSource.JtaManaged"</SPAN>, <SPAN class="code-quote">"<SPAN class="code-keyword">true</SPAN>"</SPAN>); |
| |
| Context context = <SPAN class="code-keyword">new</SPAN> InitialContext(p); |
| </PRE> |
| </DIV></DIV> |
| |
| <P>See <A href="embedded-configuration.html" title="Embedded Configuration">Embedded Configuration</A> for details on properties and overrides.</P> |
| |
| <P>See <A href="containers-and-resources.html" title="Containers and Resources">Containers and Resources</A> for a full list of supported Resource types and their properties.</P> |
| |
| <H2><A name="ConfiguringDataSourcesinTests-Noteon%3Cjtadatasource%3Eand%3Cnonjtadatasource%3E"></A>Note on <jta-data-source> and <non-jta-data-source></H2> |
| |
| <P>When configuring DataSources to be used by persistence.xml files, the DataSource supplied for <jta-data-source> is typically identical to the <non-jta-data-source>, but with the JtaManaged property set differently. Keeping with our philosophy to free you up from redundant configuration, we will happily auto-create a missing jta-data-source or non-jta-data-source based upon the supplied DataSource.</P> |
| |
| <P>In the example above, a new DataSource would be generated as an exact copy but with the name "myDataSourceUnmanaged" and its JtaManaged flag set to false. If the supplied DataSource was not JtaManaged, then the generated DataSource would be called "myDataSourceJta" and have its JtaManaged flag set to true.</P> |
| |
| <P>When relying on this functionality it is not necessary to specify the name of the generated DataSource in the persistence.xml file.</P> |
