I created a new J2EE web app project. I added JSF support from MyEclipse menu. I created a new JSF JSP page. I did not add anything to the default page. I ran the build routine. Below is the JSP page content. I get 2 errors during the build:
1. package com.sun.faces.taglib.jsf_core does not exist: com.sun.faces.taglib.jsf_core.ViewTag _jspx_th_f_view_0 = (com.sun.faces.taglib.jsf_core.ViewTag) _jspx_tagPool_f_view.get(com.sun.faces.taglib.jsf_core.ViewTag.class);
2. package com.sun.faces.taglib.jsf_core does not exist: com.sun.faces.taglib.jsf_core.LoadBundleTag _jspx_th_f_loadBundle_0 = (com.sun.faces.taglib.jsf_core.LoadBundleTag) _jspx_tagPool_f_loadBundle_var_basename_nobody.get(com.sun.faces.taglib.jsf_core.LoadBundleTag.class);

/WEB-INF/x.tldYou need to add the remaining JARs that provide the JSF implementation to your build path… while they are in your lib directory (which is good for running them) it doesn’t allow Eclipse to resolve the classes at compile time (in this case JSP validation time).
MyEclipse has a setting that defaults to “true” where it will automatically add any JARs in WEB-INF/lib to your build path, so it might be turned off or maybe you manually removed these JAR files from your build path?
Sure,
To add/remove JAR files from your project’s build path you would do the following:1) Right click on your project root node
2) Select “Properties” at th bottom.
3) Click in the left pane “Java Build Path”
4) Click in the right pane the “Java Libraries” tab
5) Here you have a few choices:-
a) Click “Add JARs” to add a JAR from your project ONLY (this is what you want to do)
b) Click “Add External JARs” to add a reference to a JAR that is anywhere on your computer
c) Click “Add Library” to add a reference to a User Library or a J2EE Library Set that MyEclipse ships with.
e) the other two buttons you can use if necessary, I don’t use them though.In our case we want to click “Add JARs” then navigate to our WEB-INF/lib directory, and add all the JAR files listed. NOTE: Eclipse will only show you JAR files that HAVE NOT already been added to your Build Path, so you don’t need to worry about adding duplicates.
Once you’ve added these libraries to your build path, go ahead and go up to the Projects menu and select “Clean”, select your project, then hit OK and Eclipse should clean and rebuild your project for you (including the JSP pages).
If you were asking about how to turn that auotmatic feature back on, it is located at: Window > Preferences > MyEclipse > J2EE Project > Web Project Deployment > “Web Project Build Path Policy”, select the first option. Now whenever JARs are added to your WEB-INF/lib dir, they will automatically be added to your build path for you.
This was the most outstanding tech support I think I’ve ever had. The turn around was unbelievable, and the simple, yet detailed explaination was so good I can hardly believe it. Thank you very very much!!!!!
