I need to give some background info before I ask the Velocity
question...
I've changed my code to use class resources instead of absolute or
relative pathnames. In other words, I changed this:
Image myImage = new Image(display, "bin/gov/noaa/ohrfc/resources/
rvf.icon.png");
to this:
Image myImage = new Image(display,
this.getClass().getResource("resources/rvf.icon.png").getFile());
This is less direct, but has several advantages, including that
getResource uses the class location (bin/gov/noaa/ohrfc) to complete
the full pathname of "resource/rvf.icon.png". The getFile() method
will return the full pathname of the file (which is: /home/oper/
workspace/GIFTS/bin/gov/noaa/ohrfc/resources/rvf.icon.png). This
makes it more portable, and makes it more compatible with using Java
Web Start for this application. Using getResource(), my code
doesn't break if I move my classes somewhere else besides "bin/gov/
noaa/ohrfc".
The problem comes in with Velocity's mergeTemplate() method which
chokes when an absolute pathname is used. It also chokes when I use
a pathname that is relative to the class location. Rather, it
requires something in between whereby I have to specify the class
location *and* the relative path to the template file, namely, I
need to specify "bin/gov/noaa/ohrfc/resources/SHEF.template",
whereas I want to specify "resources/SHEF.template" or give it the
full absolute pathname.
I am using version 1.6.1-dep. Does a later version fix this
problem? Or is there another work-around where I can either: 1)
avoid giving the class location (bin/gov/noaa/ohrfc)' or 2) give the
entire absolute path location [which can be determined on-the-fly
using getResource().getFile()]?
Could you do something like so with your absolute paths:
file.resource.loader.path = /
There may be security considerations, but you could also set the
resource loader path to something more reasonable, and within a
wrapper method around templateMerge you could remove any base
directory from the merge path.
