That was my expectation too. But it just isn't working that way for me
with AJP.
Apache httpd is listening on port 8888 and forwarding application
requests (/rs-test/*) to TomEE via AJP. TomEE is listening on ports 8080
for HTTP and 8009 for AJP requests. If the UriInfo matched the request
info, then the port number given should be 8080 when loading an app from
TomEE directly, and 8888 when using httpd to load the app via AJP.
When I request http://servername:8080/rs-test/ to get content directly
from TomEE via HTTP, the UriInfo methods match the request info, which
also matches the server.xml host name and HTTP connector port (8080).
But when I request http://servername:8888/rs-test/ to get content from
TomEE over AJP, UriInfo still lists the HTTP connector port (8080)
instead of the request port (8888). The HttpServletRequest and
HttpHeaders objects do return the request port, but UriInfo does not.
What I tried:
1. Set up the environment
1. export TESTDIR=/tmp/test
2. mkdir -p $TESTDIR
3. export JDK_HOME=/opt/java/jdk1.7.0_11
4. export PATH=$JDK_HOME/bin:$PATH
2. Download, build, and install Apache httpd
1. Download and unpack httpd-2.2.23.tar.bz2
2. cd httpd-2.2.23
3. ./configure --prefix=$TESTDIR/httpd
4. make && make install
3. Download, build, and install mod_jk
1. Download and unpack tomcat-connectors-1.2.37-src.tar.gz
2. cd tomcat-connectors-1.2.37-src/native
3. ./configure --with-apxs=$TESTDIR/httpd/bin/apxs
4. make && cp apache-2.0/mod_jk.so $TESTDIR/httpd/modules/
4. Download and unpack apache-tomee-1.5.1-jaxrs.tar.gz
5. Configure Apache httpd
1. Edit $TESTDIR/httpd/conf/httpd.conf
1. Change Listen setting to port 8888 on public IP
2. Append the following to load and configure mod_jk:
LoadModule jk_module modules/mod_jk.so
JkWorkersFile $TESTDIR/httpd/conf/workers.properties
JkShmFile $TESTDIR/httpd/logs/mod_jk.shm
JkLogFile $TESTDIR/httpd/logs/mod_jk.log
JkLogLevel info
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
JkMount /rs-test/* worker1
2. Create $TESTDIR/httpd/conf/workers.properties with the
following content:
worker.list=worker1
worker.worker1.type=ajp13
worker.worker1.host=localhost
worker.worker1.port=8009
6. Configure TomEE and create test app
1. Edit conf/server.xml:
1. Add jvmRoute="worker1" to engine configuration
2. Change Engine "defaultHost" and Host "name" values to
external host name
2. Create test application
1. Create webapps/rs-test/WEB-INF/classes/test directory.
2. Create webapps/rs-test/WEB-INF/classes/test/TestRS.java with
the following content:
package test;
import java.net.URI;
import javax.servlet.http.HttpServletRequest;
import javax.ws.rs.*;
import javax.ws.rs.core.*;
@Path("")
public class TestRS {
@GET
@Produces({MediaType.TEXT_PLAIN})
public String defaultPage(@Context UriInfo uriInfo,
@Context HttpHeaders hh, @Context
HttpServletRequest httpServletRequest) {
String response =
"uriInfo.getAbsolutePath(): "
+ uriInfo.getAbsolutePath() + "\n"
+ "uriInfo.getBaseUri(): "
+ uriInfo.getBaseUri() + "\n"
+ "uriInfo.getRequestUri(): "
+ uriInfo.getRequestUri() + "\n"
+ "httpServletRequest.getLocalAddr(): "
+ httpServletRequest.getLocalAddr() + "\n"
+ "httpServletRequest.getLocalName(): "
+ httpServletRequest.getLocalName() + "\n"
+ "httpServletRequest.getLocalPort(): "
+ httpServletRequest.getLocalPort() + "\n"
+ "httpServletRequest.getServerName(): "
+ httpServletRequest.getServerName() + "\n"
+ "httpServletRequest.getServerPort(): "
+ httpServletRequest.getServerPort() + "\n\n";
for (String header : hh.getRequestHeaders().keySet()) {
response += header + ":\n";
for (String value :
hh.getRequestHeaders().get(header)) {
response += "\t" + value + "\n";
}
}
return response;
}
}
3. Compile test class with javac -classpath
lib/javaee-api-6.0-4-tomcat.jar:lib/servlet-api.jar
webapps/rs-test/WEB-INF/classes/test/TestRS.java
7. Start services
1. Run apache-tomee-jaxrs-1.5.1/bin/startup.sh to start TomEE
2. Run httpd/bin/apachectl start to start httpd.
