I have this old Pdf generation service which was written for cq 5.5. The service is based on a servlet written for 5.5. The issue is the servlet bundle seems to be active. on 6.2 But i am not able to invoke the servlet. i have no experience working on CQ 5.5.
I think the servlet needs to be rewritten completely. below is the servlet header. In 5.5 the servlet path is actually under the /apps folder.
Also the source code is loaded in the apps folder and the transformation xsl is referenced from the /apps/src folder. The servlet is also bundled in a jar with the name - com.pdfservice.PDFService.
