Is there any easy way to. do this ..I tried exploring the options in here https://javabeat.net/how-to-debug-jsp/ But when i load the page which eventually calls this jsp ..its failing with 500 error. 

Caused by: org.apache.sling.api.scripting.ScriptEvaluationException: org.apache.sling.scripting.jsp.jasper.JasperException: Unable to compile class for JSP:

That might be syntax error

can you please provide the asp code here.

Look any jsp files in arm OOB for reference.

 

"text":"<%= jsp_variable%>"

You can do any of the following

  1. To print on page, use JSP expression <%= variableName %>
  2. To print in log file, use JSP scriptlet <% log.info(variableName) %>. Must include global.jsp and you can only print String values
  3. To print in server console, do System.out.println(variableName). Start instance using start.bat
