I believe the id accessors don t match the bean naming conventions and that s why the exception is thrown  They should be as follows   public Integer getId     return id        public void setId Integer i   id  i

javax el PropertyNotFoundException  Property  foo  not found on type com example Bean  This literally means that the mentioned class com example Bean doesn t have a public  non-static   getter method for the mentioned property foo  Note that the field itself is irrelevant here  The public getter method name must start with get  followed by the property name which is capitalized at only the first letter of the property name as in Foo  public Foo getFoo         return foo     You thus need to make sure that there is a getter method matching exactly the property name  and that the method is public  non-static  and that the method does not take any arguments and that it returns non-void  If you have one and it still doesn t work  then chances are that you were busy editing code forth and back without firmly cleaning the build  rebuilding the code and redeploying restarting the application  You need to make sure that you have done so  For boolean  not Boolean   properties  the getter method name must start with is instead of get  public boolean isFoo         return foo     Regardless of the type  the presence of the foo field itself is thus not relevant  It can have a different name  or be completely absent  or even be static  All of below should still be accessible by   bean foo   public Foo getFoo         return bar      public Foo getFoo         return new Foo  quot foo quot        public Foo getFoo         return FOO CONSTANT     You see  the field is not what counts  but the getter method itself  Note that the property name itself should not be capitalized in EL  In other words    bean Foo  won t ever work  it should be   bean foo   See also   javax el PropertyNotFoundException  Property   39 foo  39  not readable on type java lang Boolean How does Java expression language resolve boolean attributes   in JSF 1 2  Identifying and solving javax el PropertyNotFoundException  Target Unreachable Outcommented Facelets code still invokes EL expressions like   bean action    and causes javax el PropertyNotFoundException on   bean action

EL interprets   class name  as described  - the name becomes getName   on the assumption you are using explicit or implicit methods of generating getter setters  You can override this behavior by explicitly identifying the name as a function    class name     This calls the function name   directly without modification

I get the same error on my JSP and the bad rated answer was correct  I had the folowing line       lt c forEach var  agent  items     userList   varStatus  rowCounter      and get the folowing error      javax el PropertyNotFoundException  Property  agent  not found on type   java lang String   deleting the space before   userList  solved my problem  If some have the same problem  he will find quickly this post and does not waste 3 days in googeling to find help

I was facing the similar type of issue  Code Snippet      lt c forEach items    orderList   var  xx  gt           xx id   lt br gt   lt  c forEach gt   There was a space after orderlist like this      orderList    because of which the xx variable was getting coverted into String and was not able to call xx id   So make sure about space  They play crucial role sometimes   p

Check the items in forEach       lt c forEach items    pools   var  pool  gt              pool name        lt  c forEach gt    Some times items    pools   has an extra space or it acts like string  retyping it should solve the issue
