UPA NIProvider application throws java exception
Hi all,
My name is Sarun from ET 3rd level support. ET product is able to consume MarketByVolume rate from OMM feed. Therefore, ET bank normally writes their own application to feed MarketByVolume rate to ET.
This also applies to the client, the ET bank that implement their feed application based on NIProvider. The Bank (SB) usually mentions that when the application runs for a while, there is an error thrown from UPA.
Therefore, I need a consult from the community for a possible cause. Here is an error shown in the application log.

Hello @Sarun
The given exception message seems to be generated from the application source code, not the ETA API. The "com.sb.ec" package is not official UPA/ETA API package (ETA package is "com.thomsonreuters.upa").
Does the application use a modification of ETA open source code? Please confirm with the client.
Please note that the client can submit a ticket to Development team directly via GitHub issue page.
Hi All
My concern is my customer wouldn't want to reveal source code on that github page. Please advise the proper support channel where I can upload customer's source code.
regards,
Tor.
private void consumeWaitingItem(final T item, final int producerId) {
if (item == null) {
return;
}
try {
notifyListener(item, producerId);
}
catch (final Exception ex) {
LOG.error("Failed to consume item", ex);
}
}
MarketByVolume seems to be data from Matching Server so I guess that client currently uses MAPI or Matching API provided by transaction dev team and they do not use UPA API directly so you should contact MAPI support team instead.
