Subject [jira] Commented: (DERBY-3870) Concurrent Inserts of rows with XML data results in an exception
Date Wed, 10 Sep 2008 02:45:44 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3870?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12629685#action_12629685
] 

Bryan Pendleton commented on DERBY-3870:
----------------------------------------

What sort of errors are in your derby.log file? Can you attach it?

Also, can you try extracting as much information as possible from
the client-side exception by using the techniques described at
http://wiki.apache.org/db-derby/UnwindExceptionChain
then posting that information?

What JDK and XML parser are you using?

>             Project: Derby
>          Issue Type: Bug
>          Components: SQL
>    Affects Versions: 10.4.1.3
>         Environment: System: MS windows server 2003 standard edition service pack 2.
Derby is run as a server on port 1527.

>            Priority: Critical

> We insert rows into a table using the following prepared statement (through JDBC):
> INSERT INTO USER1.PSTORE values(?,?, XMLPARSE(document CAST (? AS CLOB) preserve whitespace))
> where each of the ?'s are replaced with a string.
> One thread runs fine. Two or more result in the following exception: 
> org.apache.derby.client.am.SqlException: Java exception: 'FWK005 parse may not be called
while parsing.: org.xml.sax.SAXException'.
> 	at org.apache.derby.client.am.SqlException.<init>(Unknown Source)
> 	at org.apache.derby.client.am.SqlException.<init>(Unknown Source)
> We believe that this comes from the dBuilder.parse(InputSource) method.
