java.lang.IllegalStateException: CDATA tags may not nest

Question

I\'ve got a problem with an ajax request in a JSF page. When I click on the button, I get this exception:

SEVERE: Servlet.service() for servlet Faces Servlet         


        

Answer 1

My experience to get rid of a simliar execption in Tomcat 7 is: if you are calling a method in jsf, you will have to add (), even if it does not have a parameter.

This exception but will not appear, if you are using jetty

EDIT: Even though this exception was eliminated, it gave another exception:

java.lang.NoSuchMethodError: javax.el.ELResolver.invoke(Ljavax/el/ELContext;Ljava/lang/Object;Ljava/lang/Object;[Ljava/lang/Class;[Ljava/lang/Object;)Ljava/lang/Object;

After researching I found the Tomcat 7 brings EL dependency by itself, thus any other dependency in the pom.xml like

    javax.el
    el-api
    2.2
    provided

shoud be removed to avoid the mixing.

After that, you have to start the tomcat7 by Run as - tomcat7:run in Eclipse, instead of tomcat:run which starts by default the tomcat 6.

My enviroment:

• Eclipse Kepler
• JDK 1.7.0_45
• Maven 3.1.1
