This repository is based on the original extremecomponents 1.x java code, imported from https://code.google.com/archive/p/extremetable/source/default/source
This is a minimal port of the original extremecomponents 1.0.1 code to the latest dependencies.
It is almost entirely untested, except for the minimal unit tests provided in the original codebase, and a very small use of PDF and Excel file generation.
OpenNMS has some ancient code using the original extremecomponents-1.0.1.jar to create PDFs or Excel files of one particular component.
In theory, JMesa is a substitute, but it has veered pretty far from this original API, and it seemed easier to uplift the original code to the latest dependencies rather than port our code to JMesa.
First of all, I updated most of the dependencies to the latest (or at least non-CVE-laden) versions, most notably Fop and Apache POI.
Additionally, I did a few refactorings recommended by Sonar, although there's a ton more that could be done. These changes should mostly be transparent to you other than the adaptation of some methods and classes to now support generics.
Finally, I put it under org.opennms.extremecomponents so I can publish it to Maven Central without conflicting with existing stuff.
No.
(lol)
But really, this is here mostly to solve a specific need to clean up some security issues in dependencies without breaking existing functionality. I have no intention of keeping this up-to-date unless a transient dependency becomes problematic, or we find a regression from how things used to work.
Use at your own risk.
No really, do not use this. Please. I beg of you.
