Hi,
I am facing a problem while running my Service Assembly on Servicemix
running on Jboss. Entire Servicemix hangs when I send request to this
component (through a queue).
The component that is causing problem is a SE that we have developed. This
SE (com-jms-bulk-se service engine) is written similar to servicemix-jms
Service engine. This component listens for a jms message and then sends it
to an EIP component.
In the log file it is seems like it is getting stuck at
channel.sendSync(exchange) method call. All the subsequent requests are
getting stuck at the same place.
The strange this is that this code has been working perfectly in standalone
servicemix component for about a month. But when we deploy it on SM running
on Jboss we get this issue. The same SA has an http endpoint. Even the
requests sent to that endpoint doesn't return. That request also gets stuck
at "[org.apache.servicemix.jbi.nmr.flow.seda.SedaFlow] Called Flow send"
line. I have provided the log below.
Can someone pls help us in identifying this issue.
Here is the code snippet from where it is invoked
<code>
public void onMessage(final String messages) {
try {
if (log.isDebugEnabled()) {
log.debug("Received jms messages " + messages);
}
MessageExchange exchange = toNMS(messages);
if (!channel.sendSync(exchange)) {
throw new IllegalStateException("Exchange has
been aborted");
}
if (exchange.getStatus() == ExchangeStatus.ACTIVE) {
log.debug("Channel still active. Setting status
to DONE");
exchange.setStatus(ExchangeStatus.DONE);
channel.send(exchange);
log.debug("Channel status set to DONE");
}
} catch (Throwable e) {
log.error("Error while handling jms message", e);
}
log.debug("Exiting onMessage");
}
</code>
Following is the debug log -
