Archiva 2.2.0. is up and running on a VM (CentOS 6.6).
The VM can access the internet behind a proxy.
For example, GET repo1.maven.org works well:
...
<body>
<div id="top"></div>
<div id="container">
<p>Browsing for this directory has been disabled.</p>
<p>View this directory's contents on http://search.maven.org instead.</p>
<p>Find out more about The Central Repository.</p>
<div id="footer-spacer"></div>
</div>
<div id="footer">
About Central | Terms of Service
</div>
</body>
...
Two remote repositories are configured, both with the same proxy.
But unfortunately, I always get the same connection timeout exception. See below the exception for one of the configured remote repository (Central).

Am I missing something?
Thanks!
You need to configure https://repo.maven.apache.org/maven2
and setup an https proxy.
Because even if you http://repo.maven.apache.org/maven2 there is a redirection https protocol.
That should work.

With the update to Android 11 this wonderful captive portal solution stopped working: https://github.com/ConnectBox/simple-offline-captive-portal
The problem is that on my Pixel3 with Android 11 the captive portal page will not close after clicking the OK button. It just remains open and the wifi is not accepted.
After looking into the requests I am really lost why that happens as I do not see any difference between Android 10 and Android 11:
Android 10
"POST /generate_204 HTTP/1.1" 200 7520 "http://connectivitycheck.gstatic.com/generate_204" "Mozilla/5.0 (Linux; Android 10; Pixel 3 Build/QP1A.190711.020.C3; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/78.0.3904.90 Mobile Safari/537.36"
"GET /generate_204 HTTP/1.1" 204 0 "-" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.32 Safari/537.36"
...(several GET requests) ...
"GET /generate_204 HTTP/1.1" 204 0 "-" "Dalvik/2.1.0 (Linux; U; Android 10; Pixel 3 Build/QP1A.190711.020.C3)"
....
Android 11
"POST /generate_204 HTTP/1.1" 200 7584 "http://connectivitycheck.gstatic.com/generate_204" "Mozilla/5.0 (Linux; Android 11; Pixel 3 Build/RP1A.201005.004; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/86.0.4240.75 Mobile Safari/537.36"
"GET /generate_204 HTTP/1.1" 204 0 "-" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.32 Safari/537.36"
"GET /gen_204 HTTP/1.1" 204 0 "-" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.32 Safari/537.36"
Android 10 works like a charm - Android 11 stopped working after the OK button.
Any help - experience how to get captive portals with Android 11 working - ideas how to debug this are welcome.
I already tried logging HTTP and DNS traffic on the raspberry the captive portal is running on but nothing that seems to be leading to that error.
I think the Problem is the App Android System WebView.
For me it was needed to update after the Systemupdate, because there were many Apps which crashed, including the Captive Portal.
I'm new to go-micro, tried to have micro server running as another service in my docker-compose setup however my first micro-service is not getting show in Micro Web (the Go Micro dashboard). If I run micro server outside docker-compose I can see several go-micro-related micro-services in the dashboard, but inside docker-compose none is displayed.
I have put together an example code that reproduces what I experience, I generated the service using micro new and changed nothing in it, the docker-compose.yml reflects how I have it setup in my project where I began experiencing this:
https://github.com/shackra/go-micro-docker-compose-bug
What am I doing wrong and how do I get the Micro dashboard to work as expected inside docker-compose?
EDIT
I have added a network in docker compose without any luck, also made my example service compilable inside docker.
EDIT 2
if I restart the service micro complains about it:

I don't really get it, why would it report no services nor clients were found but still being able to connect with my service?
it seems that despite micro's dashboard showing nothing, if I issue micro list services my example service is listed
I then removed the network from the docker-compose.yml, stopped docker-compose and put it up again, issued micro list services again and my example service was included in the listing. So, this seems to be a bug with the dashboard itself.
I'm running http4s WS example from:
https://github.com/http4s/http4s/blob/master/examples/blaze/src/main/scala/com/example/http4s/blaze/BlazeWebSocketExample.scala
And I'm trying to connect to it from google chrome console:
var ws = new WebSocket("ws://localhost:8080/http4s/wsecho")
ws.send("Hi")
But actually I see no messages. In console log I see
Uncaught DOMException: Failed to execute 'send' on 'WebSocket': Still in CONNECTING state.
at <anonymous>:1:4
(anonymous) # VM204:1
VM186:1 WebSocket connection to 'ws://localhost:8080/http4s/wsecho' failed: Connection closed before receiving a handshake response
And server logs contain no errors:

What do I miss?
You simply aren't waiting until the websocket connection is actually open. Try this instead:
var ws = new WebSocket("ws://localhost:8080/http4s/wsecho")
ws.onopen = function(e) { ws.send("Hi") }
If you want, you can change the WebSocketBuilder definition to this so that you have some more visibility of what's being sent:
WebSocketBuilder[F].build(d.observe1(wsf => F.delay{print(wsf)}), e)

I am trying to make a simple web application that adds a user to a database. I am using GWT-RPC with Hibernate, MySQL, and Eclipse IDE, all on Windows 7. I learnt through a tutorial how to save/add/delete values in a database using Hibernate, as well as how to do GWT-RPC from a GWT tutorial. Now, I'm trying to merge the two in a very simple program.
When starting the application through Eclipse, I get the following errors:
[WARN] Server class 'org.hibernate.Session' could not be found in the web app, but was found on the system classpath
[WARN] Adding classpath entry 'file:/D:/enterprize/MyFirstHibernateApp/lib/hibernate3.jar' to the web app classpath for this session

From the last part of the stack trace, it appears that SLF4J library is somehow not visible. However, I clearly have the library in my path:
\lib\antlr-2.7.6.jar
\lib\commons-collections-3.1.jar
\lib\dom4j-1.6.1.jar
\lib\hibernate3.jar
\lib\hibernate-cglib-repack-2.1_3.jar
\lib\hibernate-entitymanager-4.0.0.CR5.jar
\lib\javassist-3.4.GA.jar
\lib\jta-1.1.jar
\lib\mysql-connector-java-5.1.18-bin.jar
\lib\slf4j-api-1.6.4.jar
\lib\slf4j-simple-1.6.4.jar
Make sure to put all the libraries in war/WEB-INF/lib. If you have them elsewhere, remove them from the classpath first, move them, then re-add them to the classpath.
