Trying to log info from jsp file to console

[AEMnewbie]

A little new to these jsp files .. I see a jsp file which has a variable .. I am trying to find out what the variable value is ,by logging it to the console .. 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
