[teiid-issues] [JBoss JIRA] (TEIID-2786) ModeShape ExecutionFactory.getMetadata fails with java.sql.SQLFeatureNotSupportedException

[Van Halbert (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-2786?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12934786#comment-12934786 ] 

Van Halbert commented on TEIID-2786:
------------------------------------

Here are some initial observations that may require more work on the Modeshape side:

-  we know ModeShape doesn't support certain methods (i.e., getTypeInfo(..), getIndexes) which some are going to be done in the future
-  in the ModeShape metadata, an UNDEFINED type is being created and causing an issue.   The value of the type is java.lang.Integer, but the jcr PropertyType's dosn't have an Integer.   And because its UNDEFINED,  when DatabaseMetaData.getColumns(..) is called, an error occurs in addColumns(…) method, row:    int type = columns.getInt(5);
-  In the same addColumns(..) method, row:  column.setNullType(NullType.values()[columns.getShort(11)]);
fails because getShort(..) isn't implemented.   But I'm not sure this is ModeShape issue, cause the dataType of the column is  int.

After making some adjustments, more UNDEFINED types were seen.   So a lot more has to be done here, but no time at the moment.  I'll return to this at a later date.

> My guess is the local modeshape jdbc driver hasn't been fully vetted in this area, as the remote JDBC version has been the one used when using the Modeshape eclipse plugin for importing the metadata.
