wrapper-user — User issues for Wrapper. (Support questions, etc.)

[Wrapper-user] mapped network drives

[Philip M. <phi...@sw...>]

i am having problems with orion and the java service wrapper with 
network drives...

basically, if i start orion from the console my web-app is ok....if i 
run it as a service it cannot see the drives...

i am logged in as administrator when i run the service and i have even 
tried to set the user that the service uses to administrator...

no matter what i do (been through the docs here and on web) i can't 
seem to get the network drive to be seen by my web-app....

i can only think that it is some king of local network issue...????

any ideas...?

Re: [Wrapper-user] System.out deadlock

[Leif M. <le...@ta...>]

Andreas,
    Actually that is correct.   The problem was that up through version 
3.0.5, if a user
overrode the System.out or System.err print streams with their own and 
that code had
problems which lead to a dead lock or some other problem then the 
Wrapper was
being restarted in a way that made it look like a Wrapper bug.

    Another issue was that if the user redirected the streams then the 
Wrapper debug
output would be sent off to that other location as well as the user 
output.   If you are
trying to debug the Wrapper itself, you really want to keep all of the 
wrapper output
going to the wrapper.log file so that it can all be analyzed together.

    I modified the WrapperManager in version 3.1.0 so that it now 
remembers the
original System.out and System.err print streams and always uses that to 
output
its own output.

    If the user code hangs up, the Wrapper will still be able to 
successfully log its
own debug output, thus making it possible to track down the cause of the
problem.

    The way that test works is to enable debug output, then start the 
application.
Once the test app is up and running, I press the new "Poll Users" 
button. You will
start seeing user information interspersed with the debug output.  When 
you then
press "System.out Deadlock" button, the user information should stop because
it is using the user System.out object.  But the Wrapper's debug output 
should
still continue without any problems.  When you try to stop the 
application, this
will cause some output to go to the user System.out which is 
deadlocked.  This
will result in the application never shutting down cleanly so the 
Wrapper will
have to kill it.

    I'll have to add something about this to the docs...

Cheers,
Leif

[Wrapper-user] System.out deadlock

[Andreas W. <and...@em...>]

Leif,

when running the testwrapper, clicking on the "System.out deadlock" 
button causes the JVM to hang without the wrapper recognizing it (at 
least on MacOSX, OSF1, and Irix).
What should really happen?
And what is the purpose of this test? It is not explained in the manual.

Cheers,
Andreas

Re: [Wrapper-user] wrapper.jar interchangeable?

OK, thanx for the info.
I'm using 1.4.x all the way, so it won't be a problem. :)

Re: [Wrapper-user] wrapper.jar interchangeable?

[Leif M. <le...@ta...>]

Jacques,
    The wrapper.jar file is technically the same for all platforms.  It 
is built for each
distribution on the various platforms.  I have a few people help me out 
with the
releases , so the builds are made with slightly different JDK versions.  
This results
in the jar file having a slightly different size depending on where it 
was built.

     All in all this shouldn't matter to you.   The exception is that I 
have found that
it you build the jar with JDK 1.4.1 or above then you will get errors 
when running
under a 1.2.x JVM.   I usually do Windows releases using the 1.3.1 JDK 
so this
is not an issue.  But this is not true for other releases.  If you are 
going to be using
the 1.2.x JVM, I would make use of the jar from the Windows release.
    This shouldn't matter, even though the compiler is told to build a 
1.2 version of
class files, it seems to screw things up.  Seems like a Java bug, but 
not much that
can be done about it.  Not many people are using 1.2.x anymore so it is 
probably
not much of an issue.

Cheers,
Leif

Re: [Wrapper-user] Newbie question regarding multiple main classes in the same jar file

[Leif M. <le...@ta...>]

Bjorn,
    The Wrapper is only capable of launching a single application (main 
class) per
wrapper.conf and per Wrapper invocation.   If you want to run multiple 
main files
you could easily make a "wrapper" main class which simply called all of 
your other
applications' main methods.  Main methods are simply static methods and 
can be
called like any other method.

    If you want to run them all in separate JVMs, you can easily do so 
by creating
multiple conf files.

Cheers,
Leif

Yes.  I go to great effort to make sure that all wrapper.conf files are

Hi there,=20
What is the best way to configure a wrapper for a system where there is =

that need to managed. Should I use multiple conf files, cascading conf =
files or can I do the configuration in one configuration file.

Re: [Wrapper-user] access denied when trying to start a service

[Leif M. <le...@ta...>]

Marcelo,
    When are you seeing this problem?   When you try to install the 
Wrapper as a
service or when you try to start it?

    If it is when you try to start it, what the message you get when you run
c:\myapp\bin> net start myapp
from the command prompt.

    Are you setting an account to run the service as using the
wrapper.ntservice.account property?

    Also there were a couple service related problems with 3.0.5.  This 
does not
sound like one of them, but you might want to give 3.1.0 a try.

Cheers,
Leif

    This is possible as of 3.1.0 using the new wrapper.working.dir 
property.  Be sure
to read the docs on this property before trying it out.  There are some 
interactions
that you need to be aware of to avoid problems.

[Wrapper-user] Java Service Wrapper 3.1.0 released.

[Leif M. <le...@ta...>]

Hi all,
Tanuki Software, Inc. is proud to announce the 3.1.0 release of the Java
Service Wrapper.

This release has been long in coming, but contains a number of new
features as well as several performance improvements and bug fixes.

The Wrapper website has been redesigned with a new look. Users who
register with the site now have the ability to help improve the
documentation by adding comments directly to the site.
http://wrapper.tanukisoftware.org

There have been several enhancements to the Windows version so it is now
possible to display a console when running as a service, change the
title of the console where the Wrapper is running, and access
information about the user running the Wrapper as well as the user who
is currently logged in.

One major improvement is the additional of a new Tick based timer which
makes the Wrapper handle much better when running on heavily loaded
systems. This new timer also solves problems with the system time
changing. It is beta for this release and is thus disabled by default,
but we urge you to try it out and give us some feedback so it can be
enabled for the next release. See the documentation for the
wrapper.use_system_time property.

There were many many other changes and improvements as well, so please
visit the new web site and look over the release notes.
http://wrapper.tanukisoftware.org/doc/english/release-notes.html

Be sure to let me know if you find any problems.
Happy downloading.

Cheers,
Leif

Re: [Wrapper-user] scripts on mac os x

[Dan W. <dw...@ne...>]

I double-checked the script file again on the Mac. It has unix line 
termination. It is not a binary file, I can open it with VIM or bbedit.

I can also run the mac version of the wrapper executable, as you did 
below, and also the realpath executable.

I'm stumped. I can get it to work by copying the contents of the file 
and pasting into a new file, but not by doing a save-as on the file 
that doesn't work. This is probably a weird problem with my particular 
script, maybe it has a bad byte in it or something...

  I was hoping to use the same script file for all my target platforms - 
windows, linux, solaris, and Mac.

I guess I'll take the file that works on the mac now and see if it 
works on the other platforms.

thanks.

I just realized that if I try to execute the binary wrapper executable 
rather than the shell script I get the same message you saw:

Is it possible you accidently copied the binary file instead of the 
shell script and you are now trying to execute the binary file rather 
than the shell script?

Re: [Wrapper-user] scripts on mac os x

[Andy B. <aba...@ca...>]

I use the service wrapper on Linux, Solaris, and Mac OS X.

My first thought is that it is a line-terminator issue.  I use VIM for 
editing from the terminal.  If I open a working shell script and issue 
the command ":set fileformat?" and it shows "unix", then I know the 
script will work.

% ./test-unix.sh
Hello World

However, if the fileformat is reported as "dos", then executing the 
script produces this message:

% ./test-dos.sh
tcsh: ./test-dos.sh: Command not found.

In bash I get a different error message:

bash-2.05b$ ./test-dos.sh
: bad interpreter: No such file or directory

In the case of scripts with a fileformat of "dos", I just edit them 
with VIM and issue the command "set fileformat=unix" and then save the 
file.  After that it works.

Re: [Wrapper-user] stopping wrapped java app on linux (rh9) SOLVE D

[Leif M. <le...@ta...>]

Hohan,
    Yes, that would do it.  I have seen this problem in the past as 
well.  Its not a
Wrapper related issue.  But Java does not always behave very nicely when the
jar files it is reading from are swapped out from underneath it.  A good 
thing
to avoid when possible.  I occasionally forget and run "ant deploy" 
before stopping
my app and will get this or other problems on shutdown.

Re: [Wrapper-user] scripts on mac os x

[Leif M. <le...@ta...>]

Dan,
    I have seen similar problems on Linux when the shell script is 
transferred from a
Windows machine with incorrect line feeds.  Are you sure that the line 
feeds are
correct for the Mac OS X platform?
    The Mac OS X distribution is currently shipping with standard LF (UNIX)
line feeds.  Is this correct for OS X?  I don't have any OSX systems to 
play with
myself.  I know that old Mac systems used CR line feeds??

Cheers
Leif

[Wrapper-user] scripts on mac os x

[Dan W. <dw...@ne...>]

I've used the service wrapper to deploy the same java app on windows, 
linux, and solaris. I am now moving it over to Mac OS X. I'm having a 
problem with the startup script that resides in the bin directory of 
the service wrapper deployment hierarchy. From a terminal window in OS 
X (Panther 10.3.3) , trying to start the script gets an error:

-bash: ./taskserver: cannot execute binary file

This is the exact same script that I use on all the other platforms. 
The strange thing is that if I copy the contents of the script into a 
fresh text file and save it, then I can run the copied script just 
fine. So that makes me think that the contents of the script file are 
fine, but there is something missing or wrong about the metadata for 
the script file.

Has anyone else run into this?

thanks.

RE: [Wrapper-user] stopping wrapped java app on linux (rh9) SOLVE D

[Stuijt, J. <JS...@gt...>]

Hello Leigh,

Thanks for your quick response.
As soon as you mentioned the start/stop script, I realized what the cause
was. 

I have extended the script so that all needed jar-files and other resources
for the service would be copied to a lib-run subdirectory in the bin
directory. I could then recompile without disturbing the running service.

In the script, the resources were copied before the application would really
start, but also before the application would stop! So the running JVM got
its jar-files refreshed just before stopping, and this caused the strange
error message.

Changing the script to only copy the resources in case of a start solved the
problem rightaway!

Greetings,
johan

Johan,
    From the output, I am not clear where exactly that message is coming 
from.
The Wrapper or your JVM?  I am pretty sure it is the JVM because you still
get output after the dump from the Wrapper.

    Could you enable debug output using wrapper.debug=true and then post the
resulting wrapper.log file.  Don't include output from previous runs.

    Is this happening every time?   How are you asking the Wrapper to quit?
Are you using the Wrapper scripts?

    Was there a core dump from the JVM in the directory containing the 
wrapper
binary?  It might give you more info as well.

Cheers,
Leif
