I think the only solution is to re-write your uploader to avoid this: rename, extend to other names, or use the conflicting API. The only work-around would be to run Wowza Engine but not the Manager, which I think is where the conflict is.
Yeah, it looks like a hot topic. Today I faced the same issue.
I have a number of custom modules using Apache HttpClient 4.3.x and all of them are not working with Wowza 4 because it is packaged with wms-restlet-2.1.6.jar which has HttpClient 4.1.1 incorporated.
The problem is that HttpClient 4.1.x is rare thing, it is really hard to find, on the original site
http://hc.apache.org/ there is no information about this version. I even can't find the documentation for that.
The last version of
restlet.org is 2.2 and it uses httpclient 4.3.x.
Is it possible for Wowza Streaming Engine to migrate to restlet.org-2.2 ?
