[Wrapper-user] Wrapper and Java 1.4.X

[<PB...@ba...>]

Hey

Has anyone successful used the wrapper on a Sun J2SE 1.4.X JVM ?
I'm trying to use the wrapper to start a 1.4.2beta JVM but I can't make it
work !

I'm using the 2.2.8 version of the wrapper.

This is a past form the logfile:
STATUS | wrapper  | 2003/05/21 09:34:48 | Launching a JVM...
INFO   | jvm 4    | 2003/05/21 09:34:49 | Wrapper (Version 2.2.8)
INFO   | jvm 4    | 2003/05/21 09:34:49 |
ERROR  | wrapper  | 2003/05/21 09:35:10 | Startup failed: Timed out waiting
for signal from JVM.
ERROR  | wrapper  | 2003/05/21 09:35:10 | Java Virtual Machine did not exit
on request, terminated
FATAL  | wrapper  | 2003/05/21 09:35:10 | There were 5 failed launches in a
row, each lasting less than 300 seconds.  Giving up.
FATAL  | wrapper  | 2003/05/21 09:35:10 |   There may be a configuration
problem: please check the logs.
STATUS | wrapper  | 2003/05/21 09:35:11 | <-- Wrapper Stopped



Any suggestions ?

Peer,
I would start by upgrading to version 3.0.3 and then rereading the new
integration guide.  It was not very clear in the version you are trying to
use.  There have been a lot of other improvements as well that would
make it worth your while.

Start with this page.  These docs assume you are at least at version 3.0.0.
The package names were changed as of 3.0.0 and the current docs only
refer to the new package names.  The old ones are still supported but
are now deprecated.
http://wrapper.tanukisoftware.org/doc/english/integrate.html

It is really hard to tell what the exact cause is without debug output
enabled.  But I would guess that you have integrated by using the
method of extending the WrapperListener method and that your
start method is not returning.  The WrapperManager expects that
it returns and will give the exact error you are seeing if it does not.

Do take a look at the docs though, most likely you will be able to
use one of the two helper classes and completely avoid the need
to do any Wrapper related coding.

If you found this useful, please think about supporting the project:

Cheers,
Leif.

In answer to the original question though, I use wrapper with all versions
of 1.4.1 (depends on what the developer has on their machine :-).

Not tried the 1.4.2 stuff yet (I'm surprised to see a cutting edge JVM, but
not a cutting edge Wrapper).

Oh, I missed that. My brain stopped at 1.4.x I have not yet tested the
Wrapper with the 1.4.2 JVM. I'll have to give that a try.
