[jira] [Commented] (TAP5-1910) JPA and JBoss 7 datasources
[ https://issues.apache.org/jira/browse/TAP5-1910?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13272683#comment-13272683 ]
Miguel Figueiredo commented on TAP5-1910:
-----------------------------------------
Hi,
The documentation states that namespaces should follow this rule for unqualified relative names:
Unqualified relative names like "DefaultDS" or "jdbc/DefaultDS"
should be qualified relative to "java:comp/env", "java:module/env", or
"java:jboss/env", depending on the context.
(see also https://docs.jboss.org/author/display/AS7/How+do+I+migrate+my+application+from+AS5+or+AS6+to+AS7)
But in the configuration file (e.g. standalone.xml) I have to use either java:/ or java:jboss/: "JBAS010471: Jndi name have to start with java:/ or java:jboss/"
In order to use unqualified relative names I have to create the file webapp/WEB-INF/jboss-web.xml like this:
<jboss-web>
<resource-ref>
<res-ref-name>myDatasource</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<jndi-name>java:jboss/myDatasource</jndi-name>
</resource-ref>
</jboss-web>
and the persistence unit like this:
<persistence-unit name="my-pu"
transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<non-jta-data-source>myDatasource</non-jta-data-source>
(...)
</persistence-unit>
See also: https://community.jboss.org/message/632844
In conclusion I was able to use tapestry-jpa without any change.
Best resgards,
Miguel

> Key: TAP5-1910
> URL: https://issues.apache.org/jira/browse/TAP5-1910
> Project: Tapestry 5
> Issue Type: Bug
> Components: tapestry-jpa
> Affects Versions: 5.3.2
> Reporter: Miguel Figueiredo
>
> Hello,
> I am using tapestry 5.3.2 with JBoss 7, and I'm having some problems
> when using a JBoss datasource with JPA.
> My datasource configuration:
> <datasource jta="false"
> jndi-name="java:jboss/myDatasource" pool-name="mysqlDS" enabled="true"
> use-java-context="true" use-ccm="true">
> (...)
> </datasource>
> My persistence.xml configuration:
> <persistence-unit name="my-pu"
> transaction-type="RESOURCE_LOCAL">
> <provider>org.hibernate.ejb.HibernatePersistence</provider>
> <non-jta-data-source>java:jboss/myDatasource</non-jta-data-source>
> (...)
> </persistence-unit>
> Looking at the code in the PersistenceUnitInfoImpl of tapestry-jpa
> 5.3.2 I found the following:
> private DataSource lookupDataSource(final String name)
> {
> try
> {
> // TODO: Create InitialContext with environment properties?
> final Context initContext = new InitialContext();
> final Context envContext = (Context) initContext.lookup("java:comp/env");
> return (DataSource) envContext.lookup(name);
> } catch (final NamingException e)
> {
> throw new RuntimeException(e);
> }
> }
> In JBoss 7 the env context should be retrieved from java:jboss, e.g.:
> final Context initContext = new InitialContext();
> final Context envContext = (Context)initContext.lookup("java:jboss");
> return (DataSource) envContext.lookup("myDatasource");
> Maybe a datasource lookup class could be configured here.
> Best regards,
> Miguel
