I have migrated a Web Application from MyEclipse to Eclipse WTP, and I am now in the middle of the first major upgrade to the code base and web pages after the migration, and it is frankly driving me mad that saving a JSP page causes a redeployment of the WHOLE application, as it takes time and that my backend connection does not survive the serialization-deserialization of the session object (which is non-trivial to fix). In addition to that the JSP-editor is insanely slow so I frequently have to pause to let the editor catch up to be certain where my edits go in a small JSP using JavaServer Faces. Disabling validation did not help.

The Eclipse Dynamic Web Project depends on several library eclipse projects so I cannot just tell e.g. Jetty to use the WebRoot folder, as several dependencies are then missing from the classpath.

The question is:

  • Is there a way of working – ANY way of working – with the Eclipse WTP system that does NOT imply redeploying everything every time any file is saved?

I can use Tomcat 5.5 or Jetty 6 as servers.

EDIT: Having the JSP-editor being able to keep up would be really nice too…

EDIT: The JSP-pages in question contain JSF-tags (myfaces 1.1.4, tomahawk 1.1.9), if that makes a difference?

    I’ll throw-in another suggestion, which is more of a workaround.

    You can use the FileSync plugin to synchronize your bin and webroot directories with your servlet-container. You will have to use the original installation, and not workspace metadata this way. Then, after starting the server in debug mode, everything is hot-deployed.

    I have successfully used this approach with glassfish 2.

    Another thing is to check the configuration options of the server in your Servers project (it should have a folder there). It might be the case that some debug or hot-deploy option is switched off.

    As for the speed of the JSP editor – well, disabling validation is the first thing to do, and you’ve done it. Honestly, my jsp pages (containing jsf tags, and actually using facelets) don’t have any major problems with speed. Perhaps use a fresh installation?
