Pentaho: Generate a report first and then serve it in different formats -


i've created report using pentaho report designer , saved .prpt file. i've included file in java ee application , using pentaho api's display report in different formats i.e. html, pdf, excel, etc.

is there way can generate report once , serve in different formats i.e. have sql run once. having set way huge performance improvement.

take @ report caching. new feature since platform version 4.5 - user reports can cached, on per user per session basis. if you're not maintaining session data wont cached?

it may need tweak cache configuration.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
