[Wrapper-user] confused about waitForStartMain=TRUE

[Jan V. B. <jan...@gm...>]

Hi all,

I am trying to run tomcat-6.0.18 on linux (centos 5.4) with tanuki 
wrapper 3.2.3.

This all works very nice, but now I would like the 
"/etc/init.d/tomcat-tanuki start" command to return only after tomcat is 
fully started.

I thought the 
-Dorg.tanukisoftware.wrapper.WrapperSimpleApp.waitForStartMain=TRUE 
option to be what I am looking for, but I don't seem to get it to work 
as I expect it to be supposed to work.

What I did:

I am using the WrapperSimpleApp.

I start tomcat using "org.apache.catalina.startup.Bootstrap startd".

When I enable debug logging in the wrapper, I see this:

INFO: Server startup in 19484 ms
WrapperSimpleApp: main method completed

The first line is tomcat saying it has completed starting the server. 
The second line is the tanuki wrapper saying the main method has 
returned. So it seems this is OK.

But unfortunately when I run the tanuki wrapper as the /etc/init.d 
script does:

/usr/sbin/tanukiwrapper "/usr/local/tomcat6/conf/wrapper.conf" 
wrapper.syslog.ident=tomcat6 
wrapper.pidfile="/usr/local/tomcat6/tomcat6.pid" wrapper.daemonize=TRUE

This command returns immediately. Without "daemonize" it never returns.

I would like it to return when it says "main method completed". Is this 
possible?

Thanks in advance!

Kind regards,
Jan Van Besien

Forgot to say, but ofcourse I have this in my wrapper.conf file:

wrapper.java.additional.1=-Dorg.tanukisoftware.wrapper.WrapperSimpleApp.waitForStartMain=TRUE

I've also tried with

wrapper.java.additional.1=-Dorg.tanukisoftware.wrapper.WrapperSimpleApp.waitForStartMain=100

but it makes no difference.

Kind regards
Jan

I've done some more debugging (in the tanuki wrapper code) and looked at 
more logging. As far as I can see, all is good in de Java code, for 
example the logging ends with

jvm 1    | WrapperSimpleApp: main method completed
jvm 1    | WrapperSimpleApp: start(args) end.  Main Completed=true, 
exitCode=null
jvm 1    | WrapperListener.start runner thread stopped.
jvm 1    | returned from WrapperListener.start()


But still, the native script either returns immediately 
(wrapper.daemonize=TRUE) or not at all.

What am I doing wrong or misunderstanding here?

Thanks in advance,

Jan,
We have added some code to the 3.4.0 shell script so it will now wait
for an application to start up completely.   This was not being done
in earlier versions.

Could you please try this out again with 3.4.0 and let me know how it
works for you.

Cheers,
Leif
