I have Tomcat 8.0.28 running on CentOS Linux 7.2.1511 behind Apache 2.4.6
I'm using AJP 1.3 for communication between Apache and Tomcat
Its all powered by Java 1.8
I'm having a problem with international characters when I send them as the
request *URI* (which is used by GET requests and this is a GET request).
Let's say I get the string AOËL
mod_jk log logs the bytes with the message
"ajp_connection_tcp_send_message::jk_ajp_common.c (1208): sending to ajp13
pos=4 len=1411 max=8192" (at
ajp_connection_tcp_send_message::jk_ajp_common.c) shows them to be:
41 4f c3 8b 4c
AFAIK this means the correct bytes are being sent to AJP. Is that correct?
Running remote debugging via Spring Tool Suite to hook up to my code shows
me I receive:
41 4f c3 c3 83 c2 c2 8b 4c
I have verified the incorrect bytes appear as early in the call stack as
when CoyoteAdapter.process() is invoked
I have UTF-8 specified as URIEncoding in ajp <Connector> and it has had no
Ive also specified useBodyEncodingForURI as true with no effect.
Conventional wisdom says the data is getting inadvertently as ISO-8859-1
somewhere along the line. Since the data is correct (per mod_jk.log)
heading into AJP and incorrect once CoyoteAdapter.java starts handling it
somehow, something is going wrong when the data is interpreted after being
read from the AJP port.
Is that correct?
I am at a loss as to how to correct this. The only 2 things the docs say
are to use URIEnocding="UTF-8" and useBodyEncodingForURI="true". I'm
doing that and its not working.
I am at a loss about what else to try or where to look.
If you were faced with this, what would you try? Any advice or suggestions
will be greatly appreciated.
