Looking for a way to dynamically update a webpage without requiring an external request. I have a JavaScript method that updates the page, and a Java UDP server receiving parameters from clients. Is it possible to call this JavaScript method from Java source code? Any suggestions or pointers would be greatly appreciated!
Thank you in advance!
To interpret JavaScript output, a browser runtime is necessary as far as I know (JavaScript results cannot be obtained through a raw socket). It is essential to integrate a browser (perhaps JTextPane) into your UDP server in order to achieve this.
Although DWR is often the solution, it appears stagnant with no recent advancements. It may not be possible to invoke JavaScript methods directly from Java without utilizing Ajax for asynchronous calls.
The concept of altering website content dynamically without initiating a request remains unclear to me.
Our objective was clear: - Transmit location data from an android device to a server - Display these coordinates on a map in a web browser
The challenge we faced was the need for a bridge between the server handling android data and the client displaying Google Maps.
Despite attempting to implement ActiveMQ initially, we encountered difficulties and had to pivot due to time constraints. The solution we ultimately arrived at may not be elegant, but it gets the job done.
Our current setup involves a FIFO queue on the server where coordinates are stored. The same server hosts the web page with the map. When a button is clicked, an HTTP request is sent to the server. In response, a coordinate is dequeued and returned, which is then plotted on the map using the Google Maps API.
