I am not an expert on this, but it sounds like an old el lib is still
lingering around, have you cleaned out all lib dirs tomcat has (lib and
commons/lib) of pending el jars?

Hi!
I am trying to use el-api-2.2.jar with myfaces 2.0.
as i read here:http://wiki.apache.org/myfaces/HowToEnableEl22
I even added the parameter:
<context-param>
<param-name>org.apache.myfaces.EXPRESSION_FACTORY</param-name>
<param-value>com.sun.el.ExpressionFactoryImpl</param-value>
</context-param>
However, I get this exception:
org.apache.jasper.JasperException: /root.jsp(13,2) The function library must
be used with a prefix when a default namespace is not specified
at
org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:40)
at
org.apache.jasper.compiler.ErrorDispatcher.dispatch(ErrorDispatcher.java:407)
at
org.apache.jasper.compiler.ErrorDispatcher.jspError(ErrorDispatcher.java:148)
at
org.apache.jasper.compiler.Validator$ValidateVisitor$1FVVisitor.visit(Validator.java:1478)
When I try to execute:
<h:outputText value="#{libraryBean.library('yes')}"></h:outputText>
and in my bean I have:
public String getLibrary(String type){
return type;
}
public String getLibrary(){
return "hllo";
}
when I remove the variable ('yes') - it works and returns hllo.
I tried to remove jasper-el.jar from tomcat, but i got an exception.
My jars at tomcat:
annotation-api.jar
catalina.jar
catalina-ant.jar
catalina-ha.jar
catalina-tribes.jar
el-api2.2.jar
el-impl2.2.jar
jasper.jar
jasper-jdt.jar
jsp-api.jar
servlet-api.jar
tomcat-coyote.jar
tomcat-dbcp.jar
tomcat-i18n-es.jar
tomcat-i18n-fr.jar
tomcat-i18n-ja.jar
and at the application i have:
myfaces-2.0
what am I missing?
