I am using velocity to generate HTML template based content for the email which is to be sent, and Java Mail API with Spring's MimeMessageHelper to send emails. The problem i am facing is that while rendering, HTML template is thrown to catalina.out which is making the file grow in size and that is not desirable.
I have a separate application log file where the logs are generated. Is there any way so that I can redirect this rendering to my application log file? Or may be I can stop this to be thrown at catalina.out.
Below is the details which gets written while sending email
