Subject [jira] Commented: (JCR-1907) ClassCastException when using OracleFileSystem with JBoss JNDI
Date Tue, 03 Aug 2010 18:48:16 GMT

    [ https://issues.apache.org/jira/browse/JCR-1907?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12894988#action_12894988
] 

Tihomir Surdilovic commented on JCR-1907:
-----------------------------------------

I know this is very old but still wanted to confirm with devs that this is no longer an issue
in 2.1 as now the code uses ConnectionFactory.unwrap() and does not directly pass the java.sql.Connection
when creating blobs:
http://svn.apache.org/viewvc/jackrabbit/tags/2.1.0/jackrabbit-core/src/main/java/org/apache/jackrabbit/core/util/db/Oracle10R1ConnectionHelper.java?revision=934953&view=co

 private Blob createTemporaryBlob(Connection con, InputStream in) throws Exception {
        /*
         * BLOB blob = BLOB.createTemporary(con, false, BLOB.DURATION_SESSION);
         * blob.open(BLOB.MODE_READWRITE); OutputStream out = blob.getBinaryOutputStream();
... out.flush();
         * out.close(); blob.close(); return blob;
         */
        Method createTemporary =
            blobClass.getMethod("createTemporary", new Class[]{Connection.class, Boolean.TYPE,
Integer.TYPE});
        Object blob =
            createTemporary.invoke(null, new Object[]{ConnectionFactory.unwrap(con), Boolean.FALSE,
                    durationSessionConstant});
        Method open = blobClass.getMethod("open", new Class[]{Integer.TYPE});
        ....
Can anyone please comment?

Thanks.

>             Project: Jackrabbit Content Repository
>          Issue Type: Bug
>          Components: jackrabbit-core
>    Affects Versions: 1.5.0
>         Environment: - WindowsXP, JBoss AS 4.2.0.GA, JackRabbit 1.5.0, Oracle Driver
: ojdbc14_10g.jar
>            Reporter: Eduardo Andrade
>            Priority: Minor

> When using OracleFilesystem with JNDI connection on JBOSS, the JBoss gives a org.jboss.resource.adapter.jdbc.WrappedConnection
instance and oracle driver code expects a oracle.jdbc.OracleConnection instance.
> To avoid the exception : java.lang.ClassCastException: org.jboss.resource.adapter.jdbc.WrappedConnection
cannot be cast to oracle.jdbc.OracleConnection,
> couldn't it be done something like this ? :
> public static Connection getConnection(Connection conn) {
>   if (conn instanceof WrappedConnection) {
>     return ((WrappedConnection) conn).getUnderlyingConnection();
>   }
>   return conn;
> }
> Here are the relevant repository.xml config and the Exception thrown :
> 	<FileSystem class="org.apache.jackrabbit.core.fs.db.OracleFileSystem">
> 		<param name="driver" value="javax.naming.InitialContext" />
> 		<param name="url" value="java:jdbc/SiagRepo" />
> 		<param name="schema" value="oracle" />
> 		<param name="tableSpace" value="USERS" />
