Claus Ibsen commented on CAMEL-6025:
------------------------------------
Chris, this is a good idea, to keep the modification date as just the long
which we get from the java file API.
> NumberFormatException when using File over JMS

> Key: CAMEL-6025
> URL: https://issues.apache.org/jira/browse/CAMEL-6025
> Project: Camel
> Issue Type: Bug
> Components: camel-core
> Affects Versions: 2.10.2
> Reporter: Chris Watts
> Assignee: Claus Ibsen
>
> When using the FileConsumer to send a file to a JMS queue which is then
> consumed by the FileProducer I get the following error:
> {noformat}
> 11:03:22,778 DEBUG [Camel (camel) thread #1 - JmsConsumer[queue1]]
> (MarkerIgnoringBase.java:72) - Failed delivery for (MessageId:
> queue_queue1_ID_xxxxxxxxx-1911-1359590595842-3_4_1_1_1 on ExchangeId:
> ID-xxxxxxxxx-1910-1359590595467-0-10). On delivery attempt: 0 caught:
> org.apache.camel.TypeConversionException: Error during type conversion from
> type: java.lang.String to the required type: java.lang.Long with value Thu
> Jan 31 11:03:22 EST 2013 due java.lang.NumberFormatException: For input
> string: "Thu Jan 31 11:03:22 EST 2013"{noformat}
> This is due to a Date being converted to a String when sending over JMS.
> Propose that the following line in Generic file be changed from:
> {code} if (getLastModified() > 0) {
> message.setHeader(Exchange.FILE_LAST_MODIFIED, new
> Date(getLastModified()));
> }{code}
> To:{code} if (getLastModified() > 0) {
> message.setHeader(Exchange.FILE_LAST_MODIFIED,
> getLastModified());
> }{code}
> As FileOperations can use it:
> {code} private void keepLastModified(Exchange exchange, File file) {
> if (endpoint.isKeepLastModified()) {
> Long last;
> Date date =
> exchange.getIn().getHeader(Exchange.FILE_LAST_MODIFIED, Date.class);
> if (date != null) {
> last = date.getTime();
> } else {
> // fallback and try a long
> last =
> exchange.getIn().getHeader(Exchange.FILE_LAST_MODIFIED, Long.class);
> }
> if (last != null) {
> boolean result = file.setLastModified(last);
> if (LOG.isTraceEnabled()) {
> LOG.trace("Keeping last modified timestamp: {} on file:
> {} with result: {}", new Object[]{last, file, result});
> }
> }
> }
> }{code}
> Sample route:
> {code:xml}
> <route>
> <from uri="file:/tmp/input/"/>
> <to uri="activemq:queue:test"/>
> </route>
> <route>
> <from uri="activemq:queue:test"/>
> <to uri="file:/tmp/output/?keepLastModified=true"/>
> </route>
> {code}
