I was getting the same error and nothing was wrong with my java files and packages  Later I noticed that the folder name WEB-INF was written like this  quot WEB INF quot   So correcting just the folder name solved the issue

Without further details  it sounds like an error in the import declaration of a class  Check  if all import declarations either import all classes from a package or a single class   import all classes from package    import only one type named MyClass    Edit  OK  after the edit  looks like it s a jsp problem    Edit 2  Here is another forum entry  the problem seems to have similarities and the victim solved it by reinstalling eclipse  I d try that one first - installing a second instance of eclipse with only the most necessary plugins  a new workspace  the project imported into that clean workspace  and hope for the best

I experienced this weird error too  after changing letter case in the name of a class  The file was not copied to a tomcat server as expected  I had to delete it manually and redeploy  Maybe because I use case insensitive operating system

You have to import something FROM the package  like a class  enum  or interfacee  like this   import some package SomeClass    or  import everything from the package  not recommended   import some package      edit  maybe I didn t read close enough  Where is the package you re trying to import from located on the filesystem  Is it under WEB-INF lib

I had a similar issue  In eclipse I compared my project with a sample project which is working fine  generated by a maven archetype   I found my project has missed 2 lines in   classpath file  I copied those 2 lines and it fixed the issue  It seems even though I set build path in project preferences  eclipse has not updated accordingly for some reasons    lt  xml version  1 0  encoding  UTF-8   gt   lt classpath gt       lt classpathentry kind  src  output  target classes  path  src main java   gt       lt classpathentry kind  src  output  target test-classes  path  src test java   gt           lt  classpath gt

This typically happens when mixing  in the same jsp page  static jsp import    lt   include file        with dynamic jsp import    lt jsp include page        and your type has been already imported by the  static imported  jsp  When the same type needs to be used  and then imported  by the  dynamically imported  jsp -  this generate the Exception   Only a type can be imported

I know it s kinda too late to reply to this post but since I don t see any clear answer i d do it anyway     you might wanna check out the MANIFEST MF in META-INF on your eclipse   then you might need to add the path of your class files like    Class-Path  WEB-INF classes

I had the same error message and my way to deal with it is as follows    First go check the file directory where your Tomcat is publishing your web application  e g  D  Java workspace metadata plugins org eclipse wst server core tmp1 wtpwebapps myDatatable WEB-INF classes  in which we normally put our classes  If this is not the place where you put your classes  then you have to find out where by default it is by right click your web application root name-- Build Path-- Configure Build Bath   -- Then check the  Source  Tab and find out the field value of  Default output folder   This shall be the place where Tomcat put your classes  You would see that XYZ class is not yet built  In order to build it  you could go to Menu  Project --  Clean    -- Select your web application to clean  After it s completed  try restart your tomcat server and go check the file directory again  Your class should be there  At least it works for me  Hope it helps

generate  class file separate and paste it into relevant package into the workspace  Refresh Project

If you spell the class name wrong or the class isn t on the classpath  the JSP processor will say it  resolves to a package  rather than that it doesn t exist  This was driving me crazy today as I kept not seeing a typo I d made

The tomcat folder structure has Webapps ROOT  inside where the WEB-INF folder has to be present  If you place your WEB-INF inside Webapps  tomcat is not locating the class files and jars

OK I just solved it  In the last import I added a     by copying other code examples  I guess it s the standard line ending that is required   So   lt    page import  java util      gt   lt    page import  org eresearch knowledgeportal dao CategoryDao    gt   lt    page import  org eresearch knowledgeportal model Category    gt    became    lt    page import  java util      gt    lt    page import  org eresearch knowledgeportal dao CategoryDao    gt    lt    page import  org eresearch knowledgeportal model Category     gt

Just adding yet another way of achieving this weird error To me what happened is that the classpath had a few jars from tomcat by using the TOMCAT HOME variable  I didn t have that variable set and never needed it in over a year working in my current job  But this specific project was expecting this variable in the classpath and Eclipse wouldn t tell me there was a classpath error going on

Are there more details   Is this in a JSP as in the linked webpage    If so  you can always just use the fully qualified class name  rather than    import foo bar    Baz myBaz    you can use  foo bar Baz myBaz

My bet is that you have a package called org ivec eresearch knowledgeportal model category  small c  and are running on a non-case sensitive filesystem like Windows or Mac  It seems that the compiler gets confused when a class and package exist   You can either renamed the class  Category  or the package  category  and this error will go away  Unfortunately I m not sure if this is a Tomcat or ECJ bug

I had this same issue when running from Eclipse  To fix the issue I went into the Configure Build Path and removed the src folder from the build path  Then closed and reopened the project  Then I added the src folder to the build path  The src folder contained the java class I was trying to access

If you are using Maven and packaging your Java classes as JAR  then make sure that JAR is up to date  Still assuming that JAR is in your classpath of course

So I had the same issue and just wanted to give my solution  Maybe someone faces the same problem   I had properly configured my artifact but somehow intellij mixed something up and deleted the WEB-INF folder in one of my artifacts   When I viewed the contents of my  war file every class was present in the correct folder structure  So I didn t think that anything was missing  But when I check the artifacts in Intellij and compared it to a working artifact then I realized  that the WEB-INF folder with the classes and libs were not present   Add them to the artifact and it should work   TLDR  Intellij deleted the WEB-INF Folder in my  war artifact  Just check if yours is missing aswell   Project Strucutre -  Artifacts

Well  you are not really providing enough details on your webapp but my guess is that you have a JSP with something like that    lt    page import  java util   x y Z   gt     And x y Z can t be found on the classpath  i e  is not present under WEB-INF classes nor in a JAR of WEB-INF lib    Double check that the WAR you deploy on Tomcat has the following structure   my-webapp  -- META-INF      -- MANIFEST MF  -- WEB-INF      -- classes          -- x              -- y                  -- Z class          -- another              -- packagename                  -- AnotherClass class      -- lib          -- ajar jar          -- bjar jar          -- zjar jar      -- web xml  -- a jsp  -- b jsp  -- index jsp   Or that the JAR that bundles x y Z class is present under WEB-INF lib

I got this error in Netbeans  As with most bizarre errors like this that appear out of nowhere  I resolve it by going to project properties  changing the Source Binary Format  doesn t matter to what  just something different   and doing a clean and build
