tomcat - EMMA failed to dump coverage data: java.io.FileNotFoundException: coverage.ec (Permission denied) -

-

i have done following steps.

  1. copied emma.jar classpath
  2. instrumented code , got coverage.em
  3. restarted server , checked tomcat log(no suggestion of emma collecting coverage data)
  4. started doing tests on application
  5. stopped tomcat, below when stopped tomcat.


java.io.filenotfoundexception: coverage.ec (permission denied)        @ java.io.randomaccessfile.open(native method)        @ java.io.randomaccessfile.<init>(randomaccessfile.java:236)        @ com.vladium.emma.data.datafactory.persist(datafactory.java:656)        @ com.vladium.emma.data.datafactory.persist(datafactory.java:86)        @ com.vladium.emma.rt.rtcoveragedatapersister.dumpcoveragedata(rtcoveragedatapersister.java:54)        @ com.vladium.emma.rt.rtexithook.run(rtexithook.java:32)        @ java.lang.thread.run(thread.java:701)  exception in thread "emma shutdown handler thread" java.lang.runtimeexception: emma failed dump coverage data: java.io.filenotfoundexception: coverage.ec (permission de        @ com.vladium.emma.rt.rtcoveragedatapersister.dumpcoveragedata(rtcoveragedatapersister.java:71)        @ com.vladium.emma.rt.rtexithook.run(rtexithook        @ java.lang.thread.run(thread.java:701)

does know step missing. appreciate if out.

thanks,

this error:

java.io.filenotfoundexception: coverage.ec (permission denied)

generally means don't have permission read file. verify user running application has permissions read coverage.ec, , file exists.

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
