I'm developing an application using MyBatis and I'm facing a real strange problem.
This already happened a few days ago but by uncommenting the following property on the dao-context2.xml I was able to solve
ANSWER
Answered 2021-Mar-02 at 11:32Ok, it seems that it was an error by my side.
At least to my understanding, it seems that MyBatis loads the *Mapper.xml files not when the application is loaded, but when the first query is executed.
In this case, this exception

QUESTION
I have this problem in my website: if I click on the $("#new-comment") button, jquery shows an input tag where I can write a comment, then I press enter and the new comment is added. But I have this problem: if I want to insert another comment immediately after the last insertion (without uploading the page, if I press f5 this doesn't happen), when I click on the button, jquery shows two input tags, each one appended after the other. If after having added a second comment, I want to write a third one, jquery shows three tags and so on... I think that the problem is when I use the append function on the third line, but I don't know how to solve this. (NOTE: I have written this line $newReview.remove(): because otherwise, after the enter pressing, jquery showed me another input tag with the same text I have written immediately after the new comment; this is also a problem).
...ANSWER
Answered 2020-Sep-08 at 13:57Just replace $("#new-comment").on('click', write_review);
with $("#new-comment").one('click', write_review);
QUESTION
Qt Quick WebGL Streaming is a technology by which any Qt Quick ("QML") application can display its user interface to a user connecting via a web browser. All you have to do is to start the application like this on the host:
...ANSWER
Answered 2020-Aug-20 at 12:25Here is a solution that uses the load balancer Pen to make a Qt application accessible via WebGL streaming to multiple users at the same time. It forwards an incoming connection to one of multiple Qt processes running on the same host, each of which running its own embedded web server. This kind of forwarding is exactly the job of a load balancer, just that it usually distributes connections to multiple hosts.
Caveat: In my tests, WebGL streaming in Qt 5.12.3 is fast enough for real use only in the local network, not over Internet. So you can't use it to "convert a Qt application into a web application on the cheap".
InstructionsThese instructions apply to Ubuntu 19.10, 20.04 and other Debian based distributions.
Install the Qt application on your web host.
Install the Qt WebGL platform plugin on your web host. It is not contained in the Ubuntu 19.10 distribution, for example. In such a case, you'd have to compile and install it yourself. Under Ubuntu Linux, the result should be the following file:
QUESTION
I'm new to these languages and I have a simple question, but I can't figure out how to solve it. In my jQuery file I use two spans (the name of who has written a comment and the comment itself); these two spans are in the same
(I have copied the jQuery code necessary for this question, so some variables may not have been initialized here, but the code itself is correct).
EDIT
I've also uploaded my css, but now it inserts the second name immediately after the first comment (on the same line).
