Apache mod_jk and Tomcat
Dear list, we use Apache 1.3, Tomcat 4.1 and mod_jk The first request to my jsp-page shows an Internal Server Error The second Request and all following requests are handled corretly. Is there a possibility to set a timeout for mod_jk? I tried some configurations with Apache.Timeout and Tomcat.Connector.timeout - but with no success. somebody an idea? regards Carsten - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: help with tomcat 5 - mod_jk2 - apache 2
Hi,
perhaps it is only a typo, but
stickSession=1 is wrong should be
stickySession=1
Another thing is naming of jvmRoute=localhost:1009. We didn't include port here.
The jk2.properties file is empty in our configuration.
hope this helps a bit.

Hey there,
I've been searching for a long time know and can't seem to find a
solution. I'm settin up a new production server (pIV 4 gig mem) and wanted
to run 1 apache in front of several tomcat instances.
I've set the whole thing up and it works almost, only the stickySession
attribute isn't getting picked up right or something. If I try to access
our application I get switched between the 2 instances.
here is my workers2.properties file:
[shm]
info=Scoreboard. Required for reconfiguration and status with multiprocess
serversfile=/tmp/jk2.shm
size=100
[lb:lb_01]
info=Default load balancer.
debug=0
stickSession=1

tomcatId=localhost:11009
lb_factor=100
group=lb_01
[channel.socket:localhost:12009]
tomcatId=localhost:12009
lb_factor=100
group=lb_01
[status:status]

one tomcat instance
jk2.properties
## COMMENTS WILL BE _LOST_
## DOCUMENTATION OF THE FORMAT IN JkMain javadoc.
# Set the desired handler list
# handler.list=apr,request,channelJni
#
# Override the default port for the socketChannel
channelSocket.port=11009
# Default:
# channelUnix.file=${jkHome}/work/jk2.socket
# Just to check if the the config is working
# shm.file=${jkHome}/work/jk2.shm
# In order to enable jni use any channelJni directive
# channelJni.disabled = 0
# And one of the following directives:
# apr.jniModeSo=/opt/apache2/modules/mod_jk2.so
# If set to inprocess the mod_jk2 will Register natives itself
# This will enable the starting of the Tomcat from mod_jk2
# apr.jniModeSo=inprocess
server.xml (what is off importance)
Engine name=Standalone defaultHost=localhost debug=0
jvmRoute=localhost:11009
Connector port=11009
enableLookups=false redirectPort=8443 debug=0
protocol=AJP/1.3 /
1 thing what's not totaly clear to me is why you have an jk2.properties
file and still have to configure the AJP connector. I initialy thought
this was because the AJP connector worked with TCP and the jk2.properties
was for the UNIX sockets but I think I messed that one up. :)
I'm running tomcat5 latest release and the apache 2 from debian testing.
It is the worker version. I checked it with apache2 -l and i got this
core.c
mod_access.c
mod_auth.c
mod_log_config.c
mod_logio.c
mod_env.c
mod_setenvif.c
worker.c
http_core.c
mod_mime.c
mod_status.c
mod_autoindex.c
mod_negotiation.c
mod_dir.c
mod_userdir.c
mod_alias.c
mod_so.c
this is correct no?
these mods are enabled:
cgi.load cgid.conf cgid.load jk2.load ssl.conf ssl.load usertrack.load
Has anybody had this problem before? I already spent a few houres on
google and rewrote my properties file several times but always the same
result.
some last info:
Apache/2.0.49 (Debian GNU/Linux) mod_jk2/2.0.4 mod_ssl/2.0.49
OpenSSL/0.9.7d Server at 10.0.0.192 Port 80
thank you

Problem with ServletFilter
Hello, I have a Problem with ServletFilters. I am using a CacheFilter originally from Jason Falkner. This CacheFilter wraps ServletWrapper and writes outpustream to a ByteArrayStream and finally this bytearraystream is written to disk. Installing has been very easy and FIlter is working. But: every page I tested (page size from 14k to 150k) is truncated. Truncation is already in the ByteArray. The JSP-Page originally contained include directives which I evetually removed but same result. I am using tomcat 4.1.29 and mod_jk and Apache 2.0 (same result with Apache 1.3) so any idea or any suggestion? -- Mit freundlichen Grüßen Dipl.Inform.

Re: problem passing a param to a servlet
Hi Kieran, use java.net.URLEncoder.encode(tic=3,tac-4,toe=8,UTF-8); to encode your parameters before writing to HTML when you receive Parameter then you have to use java.net.URLDecoder.decode(request.getParameter(strgame),UTF-8) Carsten Kieran Buckley (AT/LMI) wrote: Hi, I am trying to pass a parameter string of structure , tic=3,tac-4,toe=8 into a servlet like as follows: a href=/myservlet?strgame=tic=3,tac=4,toe=8 I had this working on a windowns platform before I realised I should have escaped the equals sign some way.Solaris platform tomcat threw a null pointer exception in handling this value for the parameter strhgame.Is there a way for the subsequent equals to be escaped so they can be seen as part of the value?

Re: Problem with ServletFilter
Hi Jake,
flushing the writer solved the problem.
thanks a lot

Truncation is already in the ByteArray.
Are you flushing the writer in the wrapper? Hmm... Dont' have time
to go into details. I'll just past a useful working wrapper and
helper class here...

private int contentLength = 0;
private String contentType;

super(response);
output = new ByteArrayOutputStream();
}
public byte[] toByteArray() {
if (writer != null) writer.flush();
return output.toByteArray();
}
public String toString() {
if (writer != null) writer.flush();
return output.toString();
}
public ServletOutputStream getOutputStream() {
return new FilterServletOutputStream(output);
}
public PrintWriter getWriter() {
writer = new PrintWriter(getOutputStream(), true);
return writer;
}
public void sendError(int sc) throws IOException {
super.sendError(sc);
this.origStatus = sc;
}

super.sendError(sc, message);

}

return this.origStatus;
}
public void setContentLength(int length) {
this.contentLength = length;
super.setContentLength(length);
}
public int getContentLength() {
return this.contentLength;
}
public void setContentType(String type) {
this.contentType = type;
super.setContentType(type);
}

}

Re: HTTPRequest object returns null for getRemoteHost()
Hi, by default enableLookups is enabled (==true) You can add the parameter enableLookups=true to a Connector, then getRemoteHost() gives you the desired information Carsten Surendra Kumar wrote: Hi Everyone I am using Tomcat 4.1.29 and the getRemoteHost() call from HttpServletRequest is returning null.

Problems with Virtual Hosts
Hi, I installed Apache 2.0.49 and Tomcat 5.0.24. JK-Version is 2.04 My Problem is as follows: if I enter www.test.de:8080 then everything is working fine. But when I try www.test.de then tomcat invokes the default-Host (localhost). So for me it seems Apache doesn't pass the domain-name to tomcat. Has somebody an idea? thx Carsten - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
