Spring Boot, Connection abort (socket)

1. Existing Spring Boot v2.2 0 application. Java 1.8 / Windows 10. Netbeans 8.2. 2. Configurable TCP server and clients with routing between them and a yml configuration file. 3. Mostly working but breaks occasionally when TCP clients disconnect, then reconnect and send commands. SecondaryConnectionHandler Error writing data: java.net.SocketException: Software caused connection abort: socket write error 4. My guess is that the Spring application is not correctly releasing the socket / port when an external client disconnects and another external client reconnects to the same or a different port and sends commands, but this is a guess. Spring seems prone to these issues. 5. Needs stress testing to determine why issues occur and then a fix (must not break, must recover itself if a socket error occurs). 6. Also significantly loading / slowing the PC on which it is running, especially when errors occur, even with only one or two connections. 7. Please only show an interest in this work if you have considerable experience working with Spring, Java, TCP sockets and Clients / Servers.

Java program - installer

I have a Java program that implements a simple proxy server. It consists of one class file (some more may come to it later) and embedded JRE. I need to pack it into a standard windows installer. It should install the programs as a windows service. The service should be done the standard way that allows Windows to communicate with the service standardly, showing its status, starting and stopping the service. Some piece of code and a library may need to be added to the program. The installer should be able to install and uninstall the service correctly so that the uninstallation works the standard way, triggered from the Windows Applications window. The whole thing must be reasonably configurable so that I can add: app name, company name & logo, installation path, source code. Work on windows & windows server.

Conversion of Excel Spreadsheet to interactive PDF

I have a new project that we have been given by a client and they are looking at a couple of options for making it work. The basis of the project is a large XL spreadsheet, the front page (tab) is laid out and by carrying out a search in the top field, it pulls data from across the spreadsheet tabs to populate various other fields. The XL Sheet has 6 tabs, the two main tabs that it searches have 20+ columns and almost 10k rows of data. Our agency here in the UK would provide the XL sheet and the designed PDF (with fields to match those in the XL file). The aim would be to produce a PDF for iPads which replicates page 1 fields (in terms of interaction), looks pretty, but essentially pulls down from the same large spreadsheet data set. Please let me know a) is this possible in PDF format, b) how much the build might cost and c) how long you think the build might take to complete. I cannot attach the XL sheet at this time as the data is sensitive. If we get to the point of going ahead, I will try to ensure that the client thoroughly signs off the design before it comes to you, but as is the norm with these things, it would be good to also show a price for re-applying the build if a revised PDF is sent through (very likely). Please forgive me, I would guess that the £1000 fixed price was super appealing - I had not intended that as the price I would pay, but rather my upper limit. I would not expect a Java script coder a solid week of work, do let me know your competitive price for this job.

MITM Forward Proxy

We need you to create a proxy service that my browsers will use to connect through. This proxy service will route some of the requests to a real proxy server or some of them will be directly served, based on a hardcoded list of keywords. For example, for the keyword "test", we will forward to the real proxy requests like https://www.example.com/?test but not proxy requests like https://www.example.com The only way to achieve this is by intercepting SSL requests. So your app will use a self-generated SSL key that will be trusted by the browser. The proxy server that you create will also be able to authenticate to the real proxy provider. Preferably to be written in Java, but I am also open to Python or NodeJs. Parameters: - Local port - Upstream proxy hostname - Upstream proxy port - Upstream proxy username (HTTP basic auth) - Upstream proxy password - Paths to key and crt Please private message me with the turnaround time and the total cost for this, including tests.
