JBoss AS7 では理解できない非常に奇妙なエラーが発生します。基本的に、Web アプリケーションは、データを大きな POST として受け取り、データベースに格納し、格納されたデータを JAX-RS を使用して XML として応答でユーザーに返す REST アプリケーションです。これが何千回も繰り返されます。データが保存され、クライアントは完全な応答を受け取ります。
JBoss サーバーのログに次の警告/エラーが表示される以外、問題はありません。Web アプリケーションとクライアントの両方がエラーを報告せず、正常に動作します。
プロセスを開始するとすぐに、次の警告が表示されます。

調べてみると、応答が大きすぎるとこのエラーが発生する可能性があるようです。少なくともこの REST 呼び出しでは、バッファー サイズをより大きなサイズに設定したいと思います。
バッファが問題であると考えるのは正しいですか? 応答は数百キロバイト (~650 kB) になる場合があります。その場合、JBoss AS7 で応答のバッファ サイズを変更するにはどうすればよいですか? そうでない場合、他に何がありますか？
他のアイデアは大歓迎です。
編集：詳細。これは、クライアントが会話を突然中断した場合に発生する問題のようです。私はJAX-RSを使用してxmlをクライアントにマーシャリングしています
// Marshal the created message transition run to xml and return it
response = Response.status(201).entity(messageTransactionRunDomain).location(uriBuilder.build()).lastModified(new Date()).build();
クライアントは次を使用してxmlを受信しています
// Build the resource URL to get the first type . Also set the mime type.
long temptime = System.currentTimeMillis();
ClientResponse response =
webResource.type("application/vnd.neoninc.cds.processedmessage-v1.0+xml")
.post(ClientResponse.class, processedMsgIngest);
// Get the saved message transition run, so you can get the new id
if (response.getStatus() == 201) {
long endtime = System.currentTimeMillis();
log.debug("Time for " + readouts.size() + " readout values batching (seconds): " + (endtime-temptime)/1000.);
CDSRESTDataIngest.postValsTotalTime = CDSRESTDataIngest.postValsTotalTime + (endtime-temptime);
return true;
} else {
log.error("POST failed and returned a status of " + response.getStatus());
log.error(response.getEntity(String.class));
}
私が混乱しているのは、これはブラウザの会話ではないということです。クライアントはキャンセルまたはバックを押しておらず、応答ですべてが返されています...
