Directories with random numbers as foldername being created that contain .ser files

问题

So in our weblogic 10.3 server there are folders being generated with random names (such as "7nxxd", "tpy16q"). Inside each of these is the same subdirectory structure:

<randomfilename>/.tld_cache/WEB-INF/tld/
                                        c.tld/
                                        fn.tld/
                                        spring-form.tld/
                                        fmt.tld/
                                        spring.tld/
                                        tiles-jsp.tld/

Each of these directories has 2 files: crc.ser and des.ser.

Why are these files being created? Is there a way to specify the directory that they get written to besides the random name?

回答1:

JavaEE servers will frequently generate temporary working directories to hold various items, such as cahced descriptors, compiled JSPs, etc.

You can probably influence where it puts them, but that's server-specific. You'll need to read up on your server and find out how to do that.
