データファイルを受け入れてサーバーに保存するサーブレットが1つしかない単純なWebアプリがあります。「 apachecommonsFileUpload」ライブラリを使用しています。ファイルのアップロードはローカルサーバーで正常に機能します（DevおよびProdサーバーにGlassfishを使用しています）。任意のサイズのファイルをアップロードできます。これが私の記憶情報です：
-XX:MaxPermSize=512m
-Xmx1024m
これが私のサーブレットのコードです：
...
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
log.info("Let's try to do something with your request");
getMultipartRequestFile(request);
}
// Handling uploaded file with commons-fileupload library
private void getMultipartRequestFile(HttpServletRequest request){
if(!ServletFileUpload.isMultipartContent(request)) // if not is multi part then exit this function
return;
FileItemFactory factory = new DiskFileItemFactory(); // Create a factory for file items
ServletFileUpload upload = new ServletFileUpload(factory); // Create a new file upload handler
//Create a progress listener
ProgressListener progressListener = new ProgressListener(){
private long megaBytes = -1;
public void update(long pBytesRead, long pContentLength, int pItems) {
long mBytes = pBytesRead / 1000000;
if (megaBytes == mBytes) {
return;
}
megaBytes = mBytes;
if (pContentLength == -1) {
log.info("So far, " + dec.format(pBytesRead/1024.0/1024.0) + " have been read.");
} else {
log.info("So far, " + dec.format(pBytesRead/1024.0/1024.0) + "\tof " + dec.format(pContentLength/1024.0/1024.0));
}
}
};
upload.setProgressListener(progressListener);
// Parse the request
try {
List items = upload.parseRequest(request);
// Process the uploaded items
Iterator iter = items.iterator();
while (iter.hasNext()) {
FileItem item = (FileItem) iter.next();
if (item.isFormField()) {
processFormField(item);
} else {
processUploadedFile(item);
}
}
}
catch (FileUploadException e) {
e.printStackTrace();
}
}
// this is where all magic with the file will happen
private void processUploadedFile(FileItem item){
if (!item.isFormField()) {
String fieldName = item.getFieldName();
String fileName = item.getName();
String contentType = item.getContentType();
boolean isInMemory = item.isInMemory();
long sizeInBytes = item.getSize();
log.info("Field name: " + fieldName + "\nFile Name: " + fileName + "\nContent type: " +contentType+ "\nSize: " + dec.format(sizeInBytes/1024.0/1024.0));
// write uploaded file to hdd
File uploadedFile = new File(FILES_FOLDER + fileName);
try {
item.write(uploadedFile);
log.info("File location: " + FILES_FOLDER + fileName);
} catch (Exception e) {
log.warning("File cannot be writtet to the disc");
e.printStackTrace();
}
}
}

そして、これはエラーで出力されます：

これが私がdomain.xmlに追加しようとしたものです：
<http-listener acceptor-threads="1" address="0.0.0.0" blocking-enabled="false" default-virtual-server="server" enabled="true" family="inet" id="http-listener-1" port="8080" security-enabled="false" server-name="" xpowered-by="true">
<property name="maxPostSize" value="0"/> <!-- 0 means no max -->
<property name="proxiedProtocols" value="ws/tcp"/>
</http-listener>
なぜこれが起こっているのか考えてください
