I am using JSF with JDeveloper 11.
After changing any of my Java classes, everytime I have to re run whole project to make changes work.
Is there any way to build only the modified Class and continue work without stoping / starting the project?
I have no much experience in both JSF and JDeveloper and just have to make changes in project.
Well if you are just changing the JSF file you can just save and reload the browser. If you are changing other files you will need to re-run. A work around is here: http://technology.amis.nl/2009/06/26/fast-swap-in-weblogic-103-and-jdeveloper-11g-redeploy-after-compile-in-running-application/
However if you upgrade to 11.1.2.4 or 12c those versions support hot-swap and you can just save and compile all and reload with no need to re-run even when you change multiple files.
