Error with servlet reload

[Rafael Angarita]

   Hi,

   I configured my tomcat server to reload classes automatically on 
changes, however when I update the .class file I get this error  when 
try to access the page again:

HTTP Status 503 - Servlet
org.apache.catalina.INVOKER.NewContact is currently
unavailable
type Status report

message Servlet org.apache.catalina.INVOKER.NewContact
is currently unavailable
description The requested service (Servlet
org.apache.catalina.INVOKER.NewContact is currently
unavailable) is not currently available.
Apache Tomcat/4.1.27-LE-jdk14
   The catalina.log file indicates that the .class has been modified 
but the server can not  process the page...
   The environment:
   - Linux RedHat (2.4)
   - Java 1.4
   - Tomcat 4.1.27
   - The server.xml file is configured to make the Context "reloadable".

   Any suggestions?

   Thanks in advance,

Re: Error during Tomcat 3.3 startup

[Rafael Angarita]

There's another process listening on port 8007.
Check your tomcat configuration and check you are not running 2 tomcat
instances listening on the same port.

PID is process id.
Denise, if you are under Solaris try lsof (I'm not sure if the sources
are available to compile it under another platform)

Run:
# lsof -i -n -C | grep 443
it should returns the process that is using the port 443
(use -C option if you are under Solaris 5.8)

JkMount question

[Rafael Angarita]

   Hi,

   Does anybody knows if it's important the order of JkMount 
directives?, for example:

   I have two tomcat instances T1 and T2,  
   - The loadbalancer should handle all the requests to the entire site 
(and do a load balance between  T1 and T2) except for /app1 context
   - T2 should handle all the requests to /app1 context

   What's the right order of JkMount directives in my .conf file? does 
it matters?

Logs and stdout

Is there any known issue about use stdout to send  application

My programmers use to send all the messages debug and information

Problem with classNotFound and multiples contexts

[Rafael Angarita]

Hi!

I have a tomcat 3.3.1 server with two contexts, root (default) and 
c1, both of them have its own WEB-INF/lib directory. The file  j0.jar 
 is copied in each WEB-INF/lib directory but when the server starts  the 
 server indicates a ClassNotFoundException but  the class in in  j0 .jar
If I set the classpath explicitly with the j0.jar,  everything works 
fine.
It's not supposed  all the .jar  in the lib directory are included 
in the classpath for that context?

Any suggestions?, thanks in advance

Problem shutting down tomcat

process keeps alive (I have to force to finish with shutdown.sh -force 
or sending a SIGKILL)
The output from tomcat.sh

Tomcat performance problems after a while

[Rafael Angarita]

My webserver is stopping  answering requests or answers too slowly 
after a while running.
If  a http request is sent  to tomcat directly it's answered quickly 
but the same request to apache takes a lot of time to be answered 
(request a .jsp file).
If  the tomcat process is  stopped and started again (the apache is 
not stopped), the requests to apache are answered quickly.
It looks like something is happening inside the java process that 
produces a poor performance after a while, but I have no clue, how to 
look inside the java, it could be a configuration issue or  an 
application issue  but all  I  can see  is not helpful to establish the 
main reason
Any suggestion?  

The environment:
- Solaris 8
- Apache 1.3.26
- tomcat 3.2.4
- java 1.2
- TheadPool Max = 600

Thanks is advance,

Hi, I'm having a problem with tomcat and apache,  the main symptom 
is  apache  gets too slow and  the website   does not respond almost any 
request. It looks like tomcat is not responding fast enough the  apache 
requests or  tomcat  is not closing the sockets (that's why they appear 
in  IDLE state)

What I see:
- Apache gets its MaxClients  number
- A lot of sockets between  apache and tomcat  are in "IDLE" state. 
The socket between the http process and the client is closed
- The number of threads  in  tomcat are increasing  reaching 
sometimes the max configured (it's two times the MaxClients in apache)
- The java's heap is not reaching its  upper limit
- There's no memory need (scan rate keeps under 50)
- There's not CPU problem (run queue keeps under 1)
- If I increase the number of apache MaxClients, the number of http 
process reach that limit  and  most of them  turns into IDLE state.

The environment:
- Apache 1.3.26
- Tomcat 3.2.4  (using ajp12 I switched to ajp13 and it was no changes)
- Solaris 8

  Any suggestion will be  appreciated,
