If Grizzly with a StaticHttpHandler is running, and a request is made to a static file (example index.html), then that file becomes locked. That is, it is impossible to edit and save index.html while Grizzly is running.
There's any solution or workaround to be able to save currently served static resources?
A possible workaround is to disable the FileCache.
HttpServer server = HttpServer.createSimpleServer();
server.getNetworkListener("grizzly").getFileCache().setEnabled(false);
If that doesn't help, I would suggest you log an issue so we can try to address it.
I couldn't find the server.getNetworkListnener method in Grizzly 2.3.16, so it worked for me when I did:
HttpServer server = GrizzlyHttpServerFactory.createHttpServer(URI.create(baseUri), rc);
StaticHttpHandler staticHttpHandler = new StaticHttpHandler("docRoot");
staticHttpHandler.setFileCacheEnabled(false);
server.getServerConfiguration().addHttpHandler(staticHttpHandler);
I struggled with this for a while. The posts above work, but only if done after the server is started.
The server turns file caching back on when you start it, if you set it to false before it is running. Make sure to turn it off after you call server.start() as shown here.
It appears the Jersey 2.3.17 / Grizzly HttpServer turns caching on when you call
server.start();
despite setting it to false prior to starting it.
server.start(); // turns file cache back on
handler.setFileCacheEnabled(false); // turn it off again
// get every NetworkListener and set it to false (as these will also lock files)
for (NetworkListener l : server.getListeners()) {l.getFileCache().setEnabled(false); }

I have an ASP.NET Core MVC application hosted on Google Compute Engine, and when I check the logs, it seems that www.mysite.com/home/index is constantly being requested even though I am not searching that URL in my browser and nobody else knows the actual URL. Why is this? I am concerned that it may be interfering with some of my processes.
I am running the app on Windows Server 2016 and I often Remote Desktop into it. Could either of these be the reason behind the logs I am getting?

This seems to pretty much repeat itself endlessly.
Thanks

For this issue, it is caused by Health checking you configured in the GCP.
The issue I am facing, is occassionally, public static void
Main(string[] args) is re-entered without my instruction.
For this issue, it is usually caused by the application recycling. Exceptions in request would not make application recycling.
The code below works fine for me if I use an http URI, but fails for equivalent https alternative. It works fine when built and run on another machine or when I include it in another app.
GetStringAsync throws an exception: “Exception thrown at 0x770B5722 (KernelBase.dll) in .exe: 0x000006F4: A null reference pointer was passed to the stub. occurred”.
ThreadPool::RunAsync(ref new WorkItemHandler([this](IAsyncAction^ action)
{
HttpClient^ client = ref new HttpClient();
auto uri = ref new Uri(L"https://....");
auto t = create_task(client->GetStringAsync(uri));
t.then([](String^ response)
{
// response should be valid.
});
}));
Running netsh winsock reset to reset the network stack seems to fix the issue!
For me, network stack reset didn't help at all, even device reboot didn't help, but your own answer have pointed me in the right direction: it wasn't my code who suddendly went mad, it was Windows. So what actually helped in my case is starting app without debugger (that is, from Start menu) - after that app continues to work fine when started from Visual Studio. It have happened a few times now, and I can confirm that it always helps.
I'm struggling to run grizzly-websockets-chat. I've successfully compiled the sample. HttpServer.createSimpleServer is running and serving a test index.html on localhost:8080. WebSocketEngine.getEngine().register("/chat", chatApplication) executes without complaint. However, localhost:8080/chat returns "Resource identified by path '/chat', does not exist.". This is not under Glassfish - just standalone Grizzly/2.2.19.
Comments in some places suggest that websocket support is off by default - I'm unable to determine how to turn it on outside of Glassfish. I have only the test index.html in docroot.. is anything else required?
I'm not running anything special on the client side - no js, nothing. I've not seen any such thing in the sample. Surprisingly, I've not found a good doc or running example. Maybe is a user problem? ;/
Looks like websocket code may be being invoked:
$ java -jar ./tyrus-client-cli-1.1.jar ws://localhost:8080/chat
# Connecting to ws://localhost:8080/chat...
# Failed to connect to ws://localhost:8080/chat due to Handshake error
Any help much appreciated!
Change your request URI to ws://localhost:8080/grizzly-websockets-chat/chat.
The ChatApplication has the following defined for isApplicationRequest():
#Override
public boolean isApplicationRequest(HttpRequestPacket request) {
return "/grizzly-websockets-chat/chat".equals(request.getRequestURI());
}
I downloaded the red5-recorder (http://www.red5-recorder.com/) , which fails to allow me to start recording. After debugging I found that the netconnection, needed to record to a media server, created does not fire a NetStatusEvent event, so essentially it fails silently. I have implemented the connection with the following minimal working example:
trace("make net connection");
nc = new NetConnection();
nc.client = { onBWDone: function():void{ trace("bandwidth check done.") } };
trace("add event listener");
nc.addEventListener(NetStatusEvent.NET_STATUS, function(event:NetStatusEvent) {
trace("handle");
});
trace("connect!");
nc.connect("rtmp://localshost/oflaDemo/test/");
trace("connect done");
The output of this piece of code is:
make net connection
add event listener
connect!
connect done
The actionscript api states that the connect-call always fires such an event:
http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/net/NetConnection.html#includeExamplesSummary
Moreover, the netconnection is not 'connected' (a state of the NetConnection object) 10 seconds after the call. I also took a look at this: NetConnect fails silently in Flash when called from SilverLight But the fix suggested by the author, swapping rtmp and http in the connection uri, do not work. Also, I tested the uri and in fact the exact same code sniplet in a personal project, where it did work. I just can not seem to find why connecting to a media server fails silently in the red5-recorder project.
The awkward part is that if I pass some random string as a conenction uri, still nothing happens (no event, no exception, no crash). Also not setting nc.client becore nc.connect(), which caused exceptions in my experience, did not cause exceptions.
Any suggestions are welcome.
You are setting the address to localshost instead localhost.
nc.connect("rtmp://localshost/oflaDemo/test/");
Correct address:
nc.connect("rtmp://localhost/oflaDemo/test/");
It seems a like a pretty fundamental question, in a running Servlet hosted on Domino I want to access Domino resources that I have wisely protected using the the very fine security of IBM Notes and Domino.
I want the Servlet to be able to read and write data to Domino whilst keeping that data from the client that called the Servlet (or xAgent) and preventing the client from writing directly.
I'd be happy to be able to get a session that represented the signer of the application. I can get a session for a registered user by calling the Servlet using ?open&login and signing in. That's not practical.
I've looked here: How can you use SessionAsSigner in a Java Bean called from an XPage? where Mark Leusink (https://stackoverflow.com/users/1177870/mark-leusink) implies the use of ExtLib's getCurrentSessionAsSigner() could be used. I've tried it, having signed the whole application with a single user id and it doesn't return a session. The answer seems to lie in the Servlet's inability to get a FacesContext object.
This feels like the answer should be obvious but it isn't to me. Any ideas?
FacesContext is JSF stuff and can be used from XAgent (=XPage).
In a servlet you can do this:
Session session = NotesFactory.createSession(null, "user", "password");
Server ID usually has no password and doing this will use the server ID:
Session session = NotesFactory.createSession();
Check the source of the WebDav project on OpenNTF. It has all the code you need
There have been lots of good answers to the original question. Thanks very much.
The solution I propose to use is to port the code I have to OSGi plugins. It appears that java code/Servlets within the NSF context are subject to security controls that are relaxed when the same code runs within the OSGi context. The code:
try {
NotesThread.sinitThread();
Session s = NotesFactory.createSession("","<my username>","<my password>");
.....
session = null;
} catch (Exception e) {
} finally {
NotesThread.stermThread();
}
Runs fine in the OSGI context, but within in an NSF produc
com.ibm.domino.osgi.core.context.ContextInfo.getUserSession()
Jason - I assume you basically want the same functionality you would get running a Web Query Save agent if you didn't select run as Web User selected, in other words as the signer of the code.
You could try setting up a internet site rule to allow basic authentication for the specific application path you wanted to use - might be worth using a subdomain for this.
Then within the Servlet call this URL, whilst setting the Basic authorization parameters (username & password).
Something like this.
URL url = new URL(URL_TO_CALL);
String authStr = "USERNAME:PASSWORD";
String authEncoded = Base64.encodeBytes(authStr.getBytes());
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");
connection.setDoOutput(true);
connection.setRequestProperty("Authorization", "Basic " + authEncoded);
InputStream is = connection.getInputStream();
