this code display image directly. want path. can display wherever want. there other ways display image in dynamic web page?

the path depends on how servlet mapped in web.xml (as don't see annotations in code). other - rather discouraged - way use data uri. see i want retrieve image mysql database using servlet , show image along user details in table
