Hi all,
I'm in need of some help with getting my application moved to AWS RHEL and
particularly to Apache 2.4. We have been on Unix and Apache 2.2 for many
years but are being required to make the move. I've read a number of
things (
https://wiki.wocommunity.org/display/documentation/Installing+a+deployment+environment+on+RedHat,+CentOS+or+Amazon+Linux
and others) about configuration for Apache 2.4 and WO but I continue to
have issues even after trying many different things. I believe that I have
a WOAdaptor that is built correctly for Linux and Apache 2.4. It seems to
load properly when I start Apache based on the log file:
Debug: init_adaptor(): ac_init succeeded
Debug: init_adaptor(): transaction_init() succeeded
Info: Reading configuration from
http://10-118-140-236.ebiz.verizon.com:1085/WebObjects/wotaskd.woa/wa/woconfig
Info: attempting to connect to 10-118-140-236.ebiz.verizon.com on port 1085
Info: Preparing to read config for host: 10-118-140-236.ebiz.verizon.com
Info: New response: HTTP/1.0 200 Apple WebObjects
Debug: Header read: last-modified: Thu, 25 Jan 2018 13:08:31 GMT
Debug: Header read: x-webobjects-loadaverage: 0
Debug: Header read: content-type: text/xml
Debug: Header read: content-length: 192
Info: content-length was set expl.: 192
Info: ac_newInstance(): added JavaMonitor:-33000 (33000)
Info: WebObjects_post_config(): WebObjects adaptor initialization succeeded.
I can access the application from WOMonitor and start instances but if I
try to access the application the way we have with Apache 2.2 I get errors
about "This page can't be displayed". If I do a direct access to my
application it runs so I'm pretty sure it's not an application issue. One
other thing I have noticed recently is that I can't get the WOAdaptor page
to display like I can on our Apache 2.2 installations. If I try something
like
https://10-118-140-236.ebiz.verizon.com/woapp/WebObjects/WOAdaptorInfo?user+password
I get "The webpage cannot be found". Where if I use a similar URL on
another server with Apache 2.2 (
https://evaltest.vzbi.com/woapp/WebObjects/WOAdaptorInfo?user+password) I
get the Server Adaptor page.
I've tried to setup my httpd.conf and webobjects.conf (apache.conf in most
documents) based on all the documentation I have read. I'm sure it must be
something pretty simple that I am missing but I just can't seem to find it.
Does anyone have documentation with steps on how to setup WO, Apache 2.4,
and AWS/Linux with configuration details, other than the link I listed
above, that I might be able to try?
Thanks,
*Terry Soles*
