[Wrapper-user] Re: Environment variables and console out and err output

[Geetha <ge...@ho...>]

Leif,

1. The first piece of set commands executed in a batch file, creates a =
unique file name to be used for logging purposes. The current date and =
time is taken and the special characters like / - : . and space are =
replaced and then used. This is not critical if the wrapper doesnt =
support this.

2. If I can redirect the console err and out output to different files, =
that would be great. This is critical since we need to monitor the =
system and debug any issues using the files. Would be glad if we could =
get this feature.=20

Thanks
Geetha

 Great, I'm glad you are finding it useful.

 I'll plead ignorant to this.  What are you expecting those various =
commands
 to do?  The only kind of variable expansion that the wrapper currently =
knows
 how to do is to expand an environment variable with the exact name =
between
 the '%' characters.   So it is going through each of your commands and=20
 looking
 for the specified environment variable.  When a variable can not be=20
 found, the
 Wrapper leaves the string as is.
=20
 So in this case, the last thing it does is look for an environment=20
 variable called
 "TS: =3D" which does not exist, so the TS variable gets the final =
string=20
 unmodified.
=20
 If you could explain what you are expecting to have happen here, and=20
 point me
 to some online docs describing the functionality, this may be something =

 could be
 a feature in a future release.  I am a bit curious.

=20
 Currently this is not possible with the Wrapper.  It takes all output=20
 from the
 JVM, err and out and merges them into a single output stream.  out =
messages
 are logged at level INFO and err at level ERROR.
=20
 As things are implemented right now, it would be difficult to get this=20
 working
 without breaking things compatibility wise for existing users.  I have=20
 one idea,
 but I'll have to look into a bit.  At the best, it would be a little =

 kludgey to
 configure however. :-/
