[xep-support] Packaging XEP into Ear file

[Alexander Peshkov]

Hello Raj,

XEP supports a special 'resource:' URL scheme that allows you to
search for files along the Java classpath. You can use this feature to
specify XEP configuration options as described in Section "3.3.XEP
Core Options" of "XEP 3.7 User Guide" (userguide.pdf). The 'resource:'
protocol will also allow you to address images packed into ear file
from XSL-FO.

In general, the simplest way to use XEP as a single JAR incudes three steps:

1. Wrap all XEP configuration files (contents of etc/, afm/, and
   hyphen/ subdirs in XEP installation) into a single jar, preserving
   the directory structure. You may want to add some top-level catalog
   as well, i.e. you can create xepresource.jar with a following structure:
   xep37/etc/
     license.txt
     fonts.xml
     ....
   xep37/afm/
     Courier.afm
     ...
   xep37/hyphen/
     hyphen.tex
     ...

2. Include xepresource.jar into the server classpath.

3. In your application set com.renderx.xep.ROOT="resource:/xep37/"
   In this case all the relative URLs used for other configuration
   options will refer to the objects inside xepresource.jar relative
   to its root directory 'xep37'.

Hope this helps.

Best regards,
Alexander Peshkov                             mailto:peshkov at renderx.com
