JSP : Getting "javax.el.ELException". Working in GlassFish, but not in Apache Tomcat

Question

First look at the following code:

<c:choose>
   <c:when test="${type != 'h'}">
      <input type="password" disabled="true" id="plainText" name="plainText"  value="<%=key%>"/>

The above code is a part of JSP that I have created. Variable type is initialized using:

pageContext.setAttribute("type", type);

This JSP is working perfectly fine when deployed and used GlassFish Server but showing javax.el.ELException: Cannot convert h of type class java.lang.String to class java.lang.Long exception when deployed on Apache Tomcat Server.

I had deployed on GlassFish server using Netbeans automatically, while deployed on Tomcat server manually using WAR file.

What exactly is the problem?

so of what type is `type` in your source code? – home Oct 02 '16 at 16:30 — home, Oct 02 '16 at 16:30

Maybe your glassfish uses an different EL version than Tomcat...

For more details: JSP comparison operator behaviour

Also make sure that 'type' in pageContext.setAttribute("type", type) is a string and not an INT or LONG value.

EL version in Tomcat is v3.0. I am not able to get EL version in GlassFish. Secondly, `type` is of character type. – Kush Grover Oct 03 '16 at 13:26
Found the solution..Comparing characters is to be done wih `.charAt(0)`. Thanks for the help. – Kush Grover Oct 03 '16 at 13:39

Found the solution, As type is a character. The following code: <c:when test="${type != 'h'}"> should be written as <c:when test="${type != 'h'.charAt(0)}">

Now it's working.
