    [ https://issues.jboss.org/browse/TEIID-5610?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13717213#comment-13717213 ] 

Steven Hawkins commented on TEIID-5610:
---------------------------------------

If I'm reading this correctly it appears that your json contains 0xb and the jsontoxml function is passing that into the resulting xml.  Is that correct?  This would require a change to the jsontoxml function as the default Java logic in XMLEventFactory is not handling the character escaping.

>             Project: Teiid
>          Issue Type: Bug
>          Components: VDB
>    Affects Versions: 10.2
>         Environment: Create teiid VDB containing 1 Oracle source and 1 REST service source. Define REST service like this:
> CREATE VIRTUAL PROCEDURE WS_PROCEDURE(SEARCH_INPUT varchar) RETURNS (
> FILE_ID varchar,
> FILE_NAME string
> )
> AS
> SELECT
> A.FILE_ID, A.FILE_NAME
> FROM
> (
> EXEC MY_WS.INVOKEHTTP(
> ...
> )
> ) AS F,
> XMLTABLE(
> '/myxml/response/docs' PASSING JSONTOXML('myxml', F.RESULT) COLUMNS
> FILE_ID string PATH 'fileid',
> FILE_NAME string PATH 'filename'
> )
> AS A;
> CREATE VIEW WS_VIEW AS SELECT * FROM REST_WS.WS_PROCEDURE;

> After TEIID-5294 has been fixed, we are still facing issues after an update to v10.2. Error message "TEIID30151 Error building Source for context item" when calling SQL statement on VDB connected to REST service:
