I found the solution...Just to be useful for others who research on this topic - currently it is not possible to customise mail template for task reminder or assignment.. We just have to go with task-reminder or task-assign template in jbpm.mail.templates.xml This has been raised as a feature request in JBPM forum and is not expected until release of JBPM4..so not anytime now!!
