Re: WebLogic 10 Compatibility Issue - StackOverflowError

[Ilan Rabinovitch <il...@fonz.net>]

In testing Solr 1.4 today with Weblogic it looks like the filters issue 
still exists.  Adding the appropriate entries in weblogic.xml still 
resolves it.

On first look, the header.jsp changes dont appear to be required anymore.

Would it make sense to include a weblogic.xml in the distribution to 
disable the filters or should this be an exercise for 
users/administrators who chose to deploy this under weblogic?

Ilan: It's been a long time since i tried using weblogic ... when you 
talk about adding a weblogic.xml file to prevent this bug, were any other 
changes to the web.xml file required?  (I was under the impression that 
you had to remove the Servlet Filter mapping from web.xml and use weblogic 
specific options when declaring it in weblogic.xml ... but your 
description makes me think i completley missunderstood before)

If it's possible to have a simple weblogic.xml file that can be droped 
into the solr.war and will make solr work on weblogic out of the box 
(without adversely affecting any other servlet containers) then by all 
means please open a bug and attach a patch containing the weblogic.xml 
file and mark "fix for 1.4" since this seems like an easy thing to get 
inot the 1.4 release -- assuming you're willing to help test it.
