Shreedhar Ganapathy suggested me to post my issue here, to the Web
Container team.
Can someone help me? Not sure whether this is a bug of GF3.1 or I
missed some configurations steps (I used
glassfish-3.1-b33-12_10_2010.zip)
I followed instructions as per this blog:
http://blogs.sun.com/arungupta/entry/totd_67_how_to_front (Apache and
mod_jk have been installed and configured in a Ubuntu machine and
worker.properties contains two ajp ports which points to instances of a
GF server cluster in another Ubuntu machine);
but when I deploy an app on my instances (e.g. clusterjsp), I get:
SEVERE|glassfish3.1|javax.enterprise.system.core.com.sun.enterprise.v3.
server|_ThreadID=16;_ThreadName=Thread-1;|Cannot start container web
java.lang.NullPointerException at
com.sun.enterprise.web.connector.coyote.PECoyoteConnector.configureJKPr
operties(PECoyoteConnector.java:974)
at
com.sun.enterprise.web.WebContainer.createJKConnector(WebContainer.java
:937)
at
com.sun.enterprise.web.WebContainer.postConstruct(WebContainer.java:551
)
...
And it looks like ajp ports are not exposed at all.
I had a look on the WebContainer source code; It looks like "listener"
is null @PECoyoteConnector.java:974:
File propertiesFile = new File(listener.getJkConfigurationFile());
This is what happened, I guess:
@ WebContainer.java
public void postConstruct() {
...
// Configure HTTP listeners
NetworkListeners networkListeners =
networkConfig.getNetworkListeners();
if (networkListeners != null) {
List<NetworkListener> listeners =
networkListeners.getNetworkListener();
for (NetworkListener listener : listeners) {
if
(ConfigBeansUtilities.toBoolean(listener.getJkEnabled())) {
createJKConnector(listener, httpService);
} else {
createHttpListener(listener, httpService);
}
}
}
createJKConnector(null, httpService);
...
}
I think only the second "createJKConnector" is called, passing "null"
as first attribute (listener), therefore:
protected WebConnector createJKConnector(NetworkListener listener,
HttpService httpService) {
int port = 8009;
boolean isSecure = false;
String address = null;
if (listener == null) {
String portString =
System.getProperty("com.sun.enterprise.web.connector.enableJK");
if (portString == null) {
// do not create JK Connector if property is not set
return null;
} else {
try {
port = Integer.parseInt(portString);
} catch (NumberFormatException ex) {
// use default port 8009
port = 8009;
}
}
} else {
port = Integer.parseInt(listener.getPort());
isSecure =
Boolean.valueOf(listener.findHttpProtocol().getSecurityEnabled());
address = listener.getAddress();
}
if (isSecure && defaultRedirectPort == -1) {
defaultRedirectPort = port;
}
if ("any".equals(address) || "ANY".equals(address)
|| "INADDR_ANY".equals(address)) {
address = null;
/*
* Setting 'address' to NULL will cause Tomcat to pass a
* NULL InetAddress argument to the java.net.ServerSocket
* constructor, meaning that the server socket will accept
* connections on any/all local addresses.
*/
}
jkConnector = (WebConnector) _embedded.createConnector(address,
port, "ajp");
jkConnector.configureJKProperties(listener);
...
...
}
When jkConnector.configureJKProperties is called, "listener" is still
null.
This creates an NullPointerException in the "configureJKProperties"
method (in PECoyoteConnector.java)
Besides of setting GF as suggested in the Arun Gupta's blog,
asadmin create-jvm-options --target diluzio
"-DjvmRoute=\${AJP_INSTANCE_NAME}"
asadmin create-jvm-options --target diluzio
"-Dcom.sun.enterprise.web.connector.enableJK=\${AJP_PORT}"
asadmin create-system-properties --target mila
AJP_INSTANCE_NAME=mila
asadmin create-system-properties --target mila AJP_PORT=8012
asadmin create-system-properties --target luca
AJP_INSTANCE_NAME=luca
asadmin create-system-properties --target luca AJP_PORT=8013
I also created a glassfish-jk.properties file as suggested in another
blog
(
http://weblogs.java.net/blog/amyroh/archive/2006/08/glassfish_suppo.ht
ml) and run following command:
asadmin create-jvm-options --target diluzio
"-Dcom.sun.enterprise.web.connector.enableJK.propertyFile=/root/tools/g
lassfish3/glassfish/nodes/localhost-domain1/mila/config/glassfish-jk.pr
operties"
but that didn't help at all.
Commands like this are not working:
./asadmin set --host localhost
configs.config.server-config.network-config.network-listeners.network-l
istener.jk-connector.jk-enabled=true
because configs.config.server-config.network-... does not exist
and I don't even know whether I can apply commands like this one:
asadmin create-http-listener --listenerport 8012 --listeneraddress
0.0.0.0 --defaultvs server jk-connector
because I have more than one ajp ports in my cluster
