Hi everyone,
Bringing the woes of jk2+JNI again here with the dreaded "Can't find child
xx in scoreboard", since I haven't found
a satisfactory answer by anyone.
Using TC5 with Apache 2.0.x under Linux, I can get jk2 to work using
sockets. However the fun begins when
I try to use JNI.
Looking at the source from mod_jk2, I have the following snippet:
workerEnv->childId = find_child_by_pid(&proc);
if (workerEnv->childId == -1) {
int max_daemons_limit;
ap_mpm_query(AP_MPMQ_MAX_DAEMONS, &max_daemons_limit);
if (max_daemons_limit == 0) {
workerEnv->childId = 0;
env->l->jkLog(env, env->l, JK_LOG_INFO,
"jk2_init() Found child %d in scoreboard slot %d\n",
proc.pid, workerEnv->childId);
}
else {
env->l->jkLog(env, env->l, JK_LOG_ERROR,
"jk2_init() Can't find child %d in scoreboard\n",
proc.pid);
workerEnv->childId = -2;
}
} else {
env->l->jkLog(env, env->l, JK_LOG_INFO,
"jk2_init() Found child %d in scoreboard slot %d\n",
proc.pid, workerEnv->childId);
Now, the first line is the line that tries to locate the childId of the
worker in the running
server threads (if I am not mistaken). find_child_by_pid will loop through
all the active servers
trying to find the pid passed as an argument, if it fails to do so it
returns -1.
I am hazarding a guess, by saying that it must be something in my
configuration, within workers2.properties.
Is there anyone out there who can provide the definitive configuration file
and/or guidelines for workers2.properties?
The documentation on jk2 at the mo is a pile of poo (sorry guys).
Have a nice day,
Yiannis
