I have tried several solution around the web and issue still persists.

Your JSP is too large / too complicated. You need to refactor it.

The problem is that there is a hard limit imposed by the Java Virtual Machine Specification (JVMS) on the number of bytes of bytecode in a compiled Java method. Specifically, the classfile format uses a 16 bit number as the size of the method's code array.)

Java compilers are not able to automatically split a method that is too large into sub-methods. You have to do it yourself at the source code level.

With JSPs, the JSP compiler translates each JSP into a class with a single (large) Java method, unless you can refactor it by either moving some of logic into separate methods, classes or ... JSPs using "dynamic includes"; see https://stackoverflow.com/a/5484509/139985.)

We tried refactoring but its not working are there any alternate solutions?

No. There are no alternative solutions. (As far as I know.)

When I try to use dynamic include instead of include directive it is throwing a ClassNotFoundException.

That means that you made a mistake in your refactoring ... not that refactoring won't work. (You have apparently introduced a reference to a Java class with the wrong name, package or something. Or you haven't included it in class libraries that the JSP compiler has been told about.)

I faced a similar issue when I had to import a large js file onto my jsp file. I resolved the issue by adding the following lines in web.xml file of my project:

<servlet>
    <servlet-name>jsp</servlet-name>
    <servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
    <init-param>
    <param-name>fork</param-name>
    <param-value>false</param-value>
    </init-param>
    <init-param>
    <param-name>xpoweredBy</param-name>
    <param-value>false</param-value> 
    </init-param>
    <init-param> 
    <param-name>mappedfile</param-name>
    <param-value>false</param-value>
    </init-param>
    <load-on-startup>3</load-on-startup>
</servlet>

This problem can be solved by following the below approach

In your tomcat server, locate the web.xml configuration file (path : tomcat_home/conf/web.xml)

Then search for "JspServlet" block

Now add the below mentioned "<init-param>" value

<init-param>
     <param-name>mappedfile</param-name>
     <param-value>false</param-value>
</init-param>

After this change your "JspServlet" block will look like this

<servlet>
    <servlet-name>jsp</servlet-name>
    <servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
    <init-param>
        <param-name>fork</param-name>
        <param-value>false</param-value>
    </init-param>
    <init-param>
        <param-name>xpoweredBy</param-name>
        <param-value>false</param-value>
    </init-param>
    <init-param>
        <param-name>mappedfile</param-name>
        <param-value>false</param-value>
    </init-param> 
    <load-on-startup>3</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>jsp</servlet-name>
    <url-pattern>*.jsp</url-pattern>
    <url-pattern>*.jspx</url-pattern>
</servlet-mapping>

Save the file and restart the Tomcat server
