Re: [Wrapper-user] Unable use wrapper linux in RHEL 4

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

Cyrene,
    Your main method is correct, but the testfile class is not public.
Change
class testfile {
to
public class testfile{

    I was able to reproduce this with a class in the root package as you 
are doing, but
it appears to work fine as a public class even if the public token is 
omitted when the
class is located in a package...  That seems wrong.
    If I attempt to run the class from java directly then it works in 
both cases... Anyone
know about any documentation where this is described.

Cheers,
Leif

Re: [Wrapper-user] Unable use wrapper linux in RHEL 4

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

Cyrene,
    It looks like you are setting everything up on the Wrapper side 
correctly.  But
I am guessing that the problem is with your testfile class.  Does it have a
public static main method?  The error is saying that the class is found 
and loaded
but that the main method could not be found.

Cheers,
Leif

Cyrene,

What method of integration are you using, 1 2 or 3. Having a copy of your
testfile.java might help identify the problem.

Many thanks,

Re: [Wrapper-user] Windows 64-bit Support

Shibu,
    I would love to support it, but as you have observed...  A user got 
it working a couple
months ago, but I was not able to get any feedback trying to get the 
makefiles set up.
The build for 3.2.0 is set up to support 64 bit builds, but the 
Makefiles do not yet work
correctly.  I would love any help.

[Wrapper-user] Windows 64-bit Support

[Shibu V. <sva...@gm...>]

All,

I see from the supported platforms information on the "Java Service Wrapper=
"
website that Windows 64-bit is not yet supported.
Secondly, I have noticed from the archives that Leif does not have access t=
o
64-bit Windows machines.

My questions are:
1) Leif: Is there any plans to support 64-bit Windows machines ?
2) Has anybody else with access to 64-bit machines successfully built the
wrapper executables ?


Thanks,
Shibu.

[Wrapper-user] Re: NetBeans

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

Yaniv,
    Please post questions to the wrapper-user mailing list in the future 
rather than
sending them to me directly.

    The bin and lib directories are only an example.  You can place the 
files
wherever you like but you will need to modify the wrapper.conf and bat files
to match your specific directory structure.  All paths in the 
wrapper.conf are
relative to the location of the wrapper.exe.   That location becomes the 
current
directory when the wrapper and jvm are launched.

Cheers,
Leif

RE: [Wrapper-user] Limit on started JVMs under NT Service

[Christian C. <car...@ap...>]

Hi Leif,

My problem seems effectively related to resource limitation.
But my PC has 1GB RAM, and the behavior is the same on a 2GB RAM host. I
also tried to reduce the JVM max memory amount, by setting the
wrapper.java.maxmemory parameter, but nothing changed.

With all JVM running, my system memory usage is around 830 MB (which is
relatively high). I tried running the processes in console, and this works
fine. So the problem really deals with the NT Service execution.

When the system refuses to start the 17th JVM, I get no error. The JVM
stdout/stderr are redirected to files. These files are empty. I had a look
in the system event loggger, and I get an error like "Service did not
respond to start command within time". I guess this error is raised because
the Wrapper detected a JVM have been killed before (as the time out
mentionned value is 30s, and the JVM are killed immediately after being
started), and did not acknowledge its startup within time.

I'm now having a look on the Apache launcher, as I noticed Tomcat process
(also started as a child of one of my NT Services, built with Java Service
Wrapper) appears to be detached from the Wrapper process.

Cheers
Christian

Re: [Wrapper-user] Limit on started JVMs under NT Service

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

Todd,
    The problem that you are seeing is unrelated to Christian's.

    Windows sends a USER_LOGGED_OUT event to all processes whenever a
user logs out.  The Wrapper protects its JVM from this signal, but the 
child JVM
that you launched was not being protected.  The default behavior of the 
JVM is
to exit when it gets this signal.

    You can disable this by adding the -Xrs jvm argument when launching 
the JVM.
Do not set this for the JVM controlled by the Wrapper as it will break some
features and is not needed anyway.

    A better option may be to launch the second JVM as its own service 
under its
own Wrapper.  Depending on what you are doing though, this may not make
sense.

    Be aware as well.  That if the JVM launched by the Wrapper crashes, the
Wrapper will restart it.  But the child JVM of the original JVM will 
still be left
running.  If the restarted JVM also launches a new child, you could run into
problems.

Cheers,
Leif

Re: [Wrapper-user] Limit on started JVMs under NT Service

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

Christian,
Another user had been running into a similar problem last year.
The Wrapper does not contain anything which should be limiting the number
of JVMs.  I have run tests with 32 JVMs, each running under their own 
Wrapper
without any problems on an XP Home edition system.  I have not tried it with
child process as you are doing however.

Are you sure it is not a resource related problem?  What is your system 
memory
usage?

Have you tried running all of these applications in console mode rather 
than as
services?

When the system refuses to start a 17th JVM, what is the exact error you are
getting.

Are you able to start a 17th JVM from a console?  How about without the
wrapper?

Cheers,
Leif

Re: [Wrapper-user] Limit on started JVMs under NT Service

[Todd W. <to...@sc...>]

This may or may not help, but we encountered an issue related to
spawning a separate VM that may provide insight.

When our app starts up it spawns a separate Java process for its
database (resulting in two processes).  We spawn the second process
using the Ant (http://ant.apache.org/) API (which I'd recommend instead
of using Runtime, by the way).  The problem we encountered was that when
the user that spawned our application logged out of Windows it killed
the database (second) process; however, the original process stayed
alive.  After experimenting for a bit we finally threw our hands in the
air and resolved it by launching the database within the same process as
the main app, so that we only had one process.

If anyone has insight into the issue I'd love to hear it.  Otherwise,
our workaround is working fine.

Kind regards,

Todd Wilson

[Wrapper-user] Limit on started JVMs under NT Service

[Christian C. <car...@ap...>]

Hi everyone,

I tried to install several NT services using the Java Service Wrapper.
Each of these services executes a JAVA program, spanning a couple of JVMs
(using basically the exec method from Runtime class).

Let say:
Service NT_SVC1 : A java application, starting 8 children JVMs
Service NT_SVC2 : A java application, starting 5 children JVMs
Service NT_SVC3 : A java application, starting 5 children JVMs


The problem I encounter is that the system refuses to start more than 16
JVMs. The 17th is killed as soon as it has been started
No matter the Wrapper started first, I'm always getting 16 JVM started.

In my example : starting NT_SVC1, then NT_SVC2, then NT_SVC3, only 3 JVMs
from NT_SVC3 are started.
If I kill 1 JVM from NT_SVC1 and I restart NT_SVC3, I notice 1 more JVM is
started from NT_SVC3.

Is there any limitation in Java Service Wrapper, or in NT services that I
reached ?

Any help would be appreciated.

Best regards,
Christian Cardinale

Re: [Wrapper-user] JWS support for OSX with Intel processor?

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

Dave,
Ok.  I think I got it all working.  But I am not a big mac user so I 
would appreciate it if
you could download the snapshot build and give it a try.  It has been 
tested on other
UNIX platforms so if it starts, I don't expect any problems.  It was 
built on a ppc system.

RE: [Wrapper-user] JWS support for OSX with Intel processor?

[Dave H. <DH...@xr...>]

Leif,

I do understand regarding the schedule.  However I just want to make a
plug for getting this into the next release.

We are working on moving an existing application using JWS on Windows to
OSX.  We thought we were all set (no PowerPC native logic) until I
thought of the JWS piece.  Having this in the next release would be
great for us.

If you cannot, we would have to make the universal binary ourselves if
we use JWS (really want to).  Is the source of this available if we have
to go down this route?  I have only used the binary usage of JWS.  By
the way, is it just a compile issue here or is there some logic changes
required to support the new Intel processor?

Re: [Wrapper-user] Mapping network drive issue..

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

Anil,
You aren't going to like my answer.  Windows places restrictions on what 
a service is
allowed to do.   By default, the wrapper runs using a SYSTEM user.  This 
user is fairly
powerful within the current machine.  But it is not allowed to access 
network files or
printers.  It is however, allowed to become interactive and thus access 
the desktop.
http://wrapper.tanukisoftware.org/doc/english/prop-ntservice-interactive.html

In order to be able to access the network as a service, you need to 
configure a
specific account to run the service as.   That account is set up to be 
able to access
the network devices you want to access before the service is started.
http://wrapper.tanukisoftware.org/doc/english/prop-ntservice-account.html
http://wrapper.tanukisoftware.org/doc/english/prop-ntservice-password.html

Unfortunately, if you have configured a non-SYSTEM account to run the 
service
as, it is no longer possible for your service to interact with the 
desktop.  This
means that your service is able to access network drives OR display a GUI,
but not both.

This is a restriction placed on the service API by the Windows OS.  It 
doesn't
make a whole lot of sense why the interactive feature would be disabled.  At
least not if the logged in user is the same as the service user.  I have 
not yet
figured out a way to work around this other than to break out the network or
GUI features into a second service and then run them both.

Most non-java services seem to handle this by having a service which is 
installed
and always running.  Then they register another non-service application 
to start
when a user logs in.  This second app creates a tray icon and or 
displays the GUI
while the service does much of the work behind the scenes.

If you or anyone else has any other ideas on how to solve this, it would be
a great improvement.  Also if you have examples of other services where 
this is
possible, it may give me hints on how to get working.  As far as I know 
though,
it isn't possible.

Cheers,
Leif

[Wrapper-user] Mapping network drive issue..

[Anil N. J. <aju...@ho...>]

Hi,
I am launching an application using the JSW and everything seems to be
working fine. However, once the GUI is launched for my application, when I
use the Java 'file browser' and try to navigate to a folder on the
'network', I am unable to do so.
If I launch the application from the JSW console, I am able to navigate to
the 'network' drive, but the same through for the application through the
windows nt service, it is unable to point to any network drive.
Suggestion/ solutions would be welcome...

Regarding this thread:

appears as though a resolution was never reached.  Does anyone have

Hi Max,

Just to clarify things, the service does start when
any user logs in. It is just the UI that is not being
displayed. You can verify this through the Service
Wrapper log and the services.msc.

Any other ideas?

It seems you were right - the window is causing this :-(
I'm attaching 2 log files - one is with a hidden window, and one wo GUI. 
The first shuts down on logout, while the second continues.

RE: [Wrapper-user] Win Server 2003 and GUI

[Max S. <MSt...@li...>]

Ajmal and Leif,

  I had the same issue before, when I worked with previous versions of the
wrapper, and from what I was able to figure out is that some of you issue
may actually be account related. I believe that when your service is
installed and started through the RDC, it is actually being installed for a
default SYSTEM user and not for you. That's why you don't see the UI and the
service my not be working for you; when you log in through RDC windows does
not know that it has to start your service since it is under a different
user. I might be wrong on some of the details, since I did this 2 years ago,
and much has change in Wrapper project since then, but I believe this was
the case then. If you or Leif determine that this is a different issue,
please let me know, otherwise this is a good place to start.
