Description Shirly Radco 2018-02-18 08:25:03 UTC

Description of problem:
Talend is not working properly with dom4j - 2.0.0.
It give exception about DocumentToFlat.java

Currently we switched to using the dom4j provided by ovirt-engine-wildfly.
See patchs: https://gerrit.ovirt.org/#/c/87476/ and https://gerrit.ovirt.org/#/c/87451/.

This means that on a dwh machine separate from the engine, we needlessly pull all of wildfly (170MB uncompressed) to get a single 307KB file (dom4j).

Version-Release number of selected component (if applicable):
4.2.0

How reproducible:
100%

Steps to Reproduce:
1. Install dwh on a seperate machine
2. See that dom4j - 2.0.0 is installed without wildfly 
3. Check that DWH is running.

Actual results:
Works only with legacy dom4j 1.6.0.

Expected results:
DWH should use dom4j -2.0.0

Severity?
Why do we plan to fix it in 4.3.0?

Comment 3 Shirly Radco 2018-02-20 11:30:46 UTC

I open an upstream issue for this https://jira.talendforge.org/browse/TDI-40133

Comment 4 Lucie Leistnerova 2018-09-11 11:14:00 UTC

Package ovirt-engine-dwh has installed only dom4j-2.0.0-4.fc28.noarch (no wildfly package) and dwh installed and running.

verified in ovirt-engine-dwh-4.3.0-0.0.master.20180705143643.fc28.noarch
on Fedora release 28 (Twenty Eight)
