visual studio code java debugger failed to attach

You need to provide the debugger with the access to the server via a specific port which would be another potential security hole for bad actors. The debugging mode slows down the server since it disables some JVM optimizations that otherwise provide the significant performance boost.Īlso, the debugging mode can be a potential security risk.

On the other hand, you wouldn’t want to always keep the production server running with debugging configuration enabled, as it could affect the performance, and definitely weaken security. This means that the configuration steps should be taken in advance. Caveatsįirst off, if you try to connect to a remote running Java server which you did not specifically configure for debugging, you’d most likely fail. In this article, you’ll discover how to configure a running web server and debug your application using standard facilities provided by the Java platform. Sometimes it involves debugging the application code directly on the server.īut the production servers are usually run in a strict environment, where not all convenient developer tools are available. Troubleshooting a problem on a remote server, especially in production, is not an easy task.
