In FireFox I load my web application which has a Source Map. The Source Map seems to be loaded correctly, as the Debugger tab shows the original source files.
However, the Console tab contains only links to the compiled code, instead of the Source Map code.
Is a Source mapping done in FireFox Console?
Do I have to enable anything?
Update: I also tried it in chrome and there the console shows the original location of the event, BUT: only the first time after starting chrome AND only, if I first load the page and then open the developer tools. Exactly same behaviour in opera (same engine...)
Update 2:
As of Firefox bug 670002 Web console does still not support source mapping.
In chrome the source mapping works more than once if I directly embed the source mapping instead of using an URL.
For chrome developer tools, the answer was covered in this issue:
https://bugs.chromium.org/p/chromium/issues/detail?id=633549
In some cases, developer tools requested the source map file when no connection was alive anymore. It tried to open a new connection, which failed silently because of an invalid ssl certificate.
You may run into this, when:
You serve using https
You do not have a valid ssl certificate (which may happen often when you just run a quick local node.js https server)
Your https server closes the connection fast or immediately
Especially when your https server sends connection:close in the response headers you may run into this.
The biggest issue is, that this request is not shown in the network tap nor in the console, it is just silent.

I want to perform load test of ios mobile app using Jmeter but I am facing issues in configuring my mobile phone. I have installed Jmeter and added recording template in it and set the port no of HTTP Test script recorder to 8888. I have also installed and trusted the certificate in my mobile device and set the proxy settings of my device by giving IP and port no. But after setting proxy I am unable to access the internet. Apps as well as other websites on chrome etc stops working due to loss of internet and when I remove proxy it starts working fine.
It's hard to say what is wrong without seeing jmeter.log file preferably with debug logging enabled for the proxy components, it can be done by adding the next line to log4j2.xml file (it's located in JMeter's "bin" folder)
<Logger name="org.apache.jmeter.protocol.http.proxy" level="debug" />
A "blind shot": in order to provide Internet access to the iOS device JMeter must have Internet access itself. Try adding a Thread Group and a HTTP Request sampler manually pointing to some site in the Internet which works for sure, i.e. http://example.com may be a good choice. Then add a View Results Tree listener and run the test. If the test fails it means that JMeter cannot access internet and most probably you need to configure it to use your corporate or ISP proxy
If the test is successful - look into the log files for JMeter and iOS and try to figure out the cause of the problem from them. If you fail to do this yourself - either update this thread with your configuration details and log files or ask a new question
Is it possible to view the network traffic (http requests, raw http etc.) similar to chrome dev tools (network tab) generated by an application (nodejs if it makes any difference) via vscode?
This functionality is already present, but it doesn't show the requests and responses of the application running.
The developer tools are connected to the running instance of Code and not the application you are executing. Currently it is not possible to view network traffic for the application you are launching from Code.
You can try to start from mbehr1.vsc-webshark plugin and use WireShark tools for catching your app network i/o.
It would be great a more detailed post about configuring launching Rust app (server) in debug mode, wireshark with VSCode integrated UI, and maybe internal browser in a single launch.json action, but I can't point anything close to it.
I am developing a Telco application (Dyanamic Web application project to send and receive sms) using Eclipse & tomcate version 7
When I try to run it on
http://localhost:8080/SMS1
It gives an error message HTTP-ERROR-CODE:302
What should I do to resolve this error
This is the link to Application and video tutorial what I am following
https://drive.google.com/file/d/0B3VmCeqDC7SDcFZaWVZhRUNmaTQ/edit?usp=sharing
HTTP code 302 is a standard "redirect" message--that is, it tells your web browser that the page was moved and where the new page can be found. I'm guessing whatever you're using as a web browser (Eclipse?) just doesn't handle that type of redirect. Try using a standard web browser like Chrome or Mozilla to see if that helps...
Also a guess, but the redirect may be trying to move you to HTTPS instead of HTTP, and your certificates may not be set up properly, or the port isn't enabled, or there may be some other problem with your HTTPS configuration. If the app is supposed to work over HTTPS, try going directly to the HTTPS version of the link to see if that's the real issue.
A third guess is the app may be trying to redirect you to a login page if you're not logged in, and maybe it can't find it. I'd need to know a lot more about the built product and I really don't want to mess with some guy's shared Eclipse project. Tell them to use a build tool!
I have deployed my GWT application on a JBoss server, which is located on a virtual machine. If I open Safari/Firefox/Chrome, clear the cache and then navigate to my app: the app fails to load! I just see a blank screen (the title is loaded).
I use SmartGWT and when I just httpfox to examine the traffic, I can see that most resources (images, javascript) is downloaded, but some SmartGWT js files seems to be hanging.
In the screenshot, ISC_core.js and ISC_Foundation.js has not been completely downloaded, and they never are. (It is not always these two files, it can also be different ones, and it changes everytime I retry).
Now, if I reload the browser my app loads perfectly and when I look in httpfox, the files that were not completely downloaded before, is now fetched from the browser cache.
If I clear the browser cache and try again: blank page and same issue.
Does anyone have a clue about what is causing this behaviour and where I should look to fix it?
Note: this only happens when I deploy on my remote virtual machine. If I deploy locally in the same JBoss server setup, I have no problem and cannot reproduce the above issue. Also no problems when I debug in Eclipse and use the Jetty server.
May be this is an Known issue ..Which is posted on Google groups .
As a side note enable gzip on your jboss also..please refer to this link to do that
i am only start learning GWT by following their tutorial on https://developers.google.com/web-toolkit/doc/2.1/tutorial/create
On that page, when i reach the heading Running the development mode code server (from Eclipse), i copied the generated url http://127.0.0.1:8888/StockWatcher.html?gwt.codesvr=127.0.0.1:9997 to my browser.
It eventually times out, says page not loading...the plugin page did not show up initially, so i manually installed the plugin...but it still times out...
On the screen, it says...
===============================================================================
The connection was reset
The site could be temporarily unavailable or too busy. Try again in a few moments.
If you are unable to load any pages, check your computer's network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web
==============================================================================
Am i missing any configurations etc?
Thanks very much in advance
It still looks like your browser is missing the GWT developer plugin. Try a different browser (preferably Chrome). You can also check the instalation of GWT in Eclipse. Look into Windows/Preferences and under Google/WebToolkit you should see checked GWT SDK. Also you can check if a jetty server runs on port 8888, when you type "netstat -na" on the command line.
