So i was trying to make my own Free Server so i watched a tutorial how to do that with Hamachi
so i tried then came this Error
i already tried to find where i can fix it or sth like that but i dont know yet.
Here is the link to the Tutorial i tried with .
https://www.youtube.com/watch?v=9RpA14YdEe0&t=154s
I´d be very happy if you can help me .

The CMS collector has been deprecated as of JDK9; you're on JDK16, and it's been entirely removed at this point. It is rather unlikely you want the CMS collector. That tutorial is rather hopelessly out of date if it is advising that you use it.
I suggest you use the Z Garbage Collector instead. It has similar properties (lots of very short collection cycles that don't freeze the entire VM), but is better. -XX:+UseZGC is how to turn it on.
It's that or downgrade to e.g. JDK8 which still has the old CMS.

I use translation to talk to you because I got tired of searching a lot in Arabic explanations and did not find a solution. I have a chat site programmed with "node.js" with a mysql database and there is a security vulnerability that some users do (check element > control panel) that puts this code "socket.emit('broadcasting', {cmd: 'send'});" is restarting the entire site. I want a solution to this problem. Is there a way to prevent users from placing this code in (check element > console)or any other solution? Thank you.
I tried obfuscating the code but it didn't work

I am not able to run the modified code, after modification still chrome is debugging older code. I can see the green color on the web page which denotes that its pointing to the local file saved in my system. But still not able to run the modified code. I am able to do so by using console to modify the js files.
I am really stuck for 3 days and now i am pretty confused whats going on. I searched on google but it seems not working.
Try the below steps-
• Clear the browser cache.
• In case you are using Visual Studio, clean and the rebuild the solution. Or do the equivalent if you are using any other IDE.

Display issues on website after selecting language [closed]

Our website has some display issues after selecting a language. Take This page for example. When we view the page in German, the following becomes clear:
The main slider is no longer able to slide
The language selector stops working
The middle section slider is half off the page and no longer able to slide.
I suspect a javascript issue after the language selection is made. Yet all files are loaded correctly. We do not know where to start looking for the issue.
I do not expect an immediate solution, but I hope that someone can point us in the right direction.
You should probably mention what technology you are using for the translations. Also the issue seems to be that you are using a sub-folder for each language. Ex: https://www.hollandmarineparts.nl works but https://www.hollandmarineparts.nl/nl doesn't.
It seems that the routes are broken for when you have a language other than default. (determined from the errors in the browser console)
EDIT: The route to yours plugins.js and scripts.js is breaking. It prints:
Uncaught SyntaxError: Unexpected token <
because it can't find them and it's returning index.html.

My website is http://hoopweb.com/. It suddenly loads so slowly. I know that it is because of a JavaScript file. Can someone help find the file? I can't experiment on all files due to some reasons.
You can open the developer tools and check in the network tab exactly which script is taking the longest time to load.
And as mayersdesign said, too many scripts = too many requests = longer page load time.
http://v2.zopim.com/bin/v/widget_v2.195.js is particularly slow, but in general you simply have too many scripts and too many loading in the head and not the footer.

I'm trying to get eBay suggested values for searching purposes against the given keyword. A prototype can be found here. Can anyone help me to figure out the problem in code?
The problem is due to the Same Origin Policy - you cannot make an AJAX call to any domain other than the current, unless the format of the request is JSONP.
The workaround is to use a server-side proxy on your domain (such as in this example) to get the XML file, and then have your jQuery load that.
