thanks, zaht works. another rpoblem is that i have to call a perl-script like this:

C:\Monitoring>check_jboss.pl -H localhost -T "ServerInfo" -J "jboss.system" -a "
ActiveThreadCount" -w 300: -c 250: -f

but this tells my that data is missing. this is the code fragment where twiddle statement is build:

# prepare command line that will be called and list of attributes hash array
my $twcall=$twiddle;
$twcall .= " -s $o_host" if defined($o_host);
$twcall .= " get " . $o_jmxmbean;
$twcall .= ":type=" . $o_datatype if $o_datatype;
$twcall .= ":service=" . $o_servicetype if $o_servicetype;
for ($i=0;$i<scalar(@o_jmxattrL);$i++) {
 $twcall .= " $o_jmxattrL[$i]";
 $dataresults{$o_jmxattrL[$i]} = ["check", undef];
}
for ($i=0;$i<scalar(@o_perfattrL);$i++) {
 $twcall .= " $o_perfattrL[$i]" if !defined($dataresults{$o_perfattrL[$i]});
 $dataresults{$o_perfattrL[$i]} = ["perf", undef];
}

ahhh, i got it. here is the complete script if someone want to use it under windows servers (script is originaly from w.leibzon!):

#
# ============================= SETUP NOTES ==================================
#
# This is a nagios plugin to check JBOSS server attributes. It requires
# local JBOSS provided twiddle utility to be available and will call it
# (and consequently JAVA process) to actually connect to JBOSS server.
# Therefore keep in mind that this plugin requires rather heavy processing
# and you're lot better off doing this through NRPE.
#
# For setup make sure to adjust path to twiddle which is rather non-standard
# in this plugin by default (/opt/jboss/bin/twiddle) and make sure you have
# either utils.pm in the directory specified with "use lib" or comment it out
# uncomment 'my %ERRORS' and 'my $TIMEOUT'.
#
# The attributes are data attributes of JBOSS bean which you must
# specify with '-J'; specifying type with '-T' is also required by
# twiddle, please see documentation for JBOSS and twiddle.
#
# For each attribute you specify in '-a' you must also specify warning
# and critical values in the same order in '-w' and '-c' (see below)
# Using '-f' would cause all attribute values to also be available
# for Nagios performance processing and with '-A' you can specify
# list of that attributes even if they are not otherwise listed in
# '-a' (you can also do '-A *' to just get all the atributes).
#
# Warning and critical levels are specified with '-w' and '-c' and each
# one must have exact same number of values (separated by ',') as number
# of attribute names specified with '-a'. Any values you dont want
# to compare you specify as ~ (or just not specify a value, i.e. ',,').
# There are also number of other one-letter modifiers that can be used
# before actual data value to direct how data is to be checked.
# These are as follows:
# > : issue alert if data is above this value (default for numeric value)
# < : issue alert if data is below this value (must be followed by number)
# = : issue alert if data is equal to this value (default for non-numeric)
# ! : issue alert if data is NOT equal to this value
# A special modifier '^' can also be used to disable checking that warn
# values are less then (or greater then) critical values (it is rarely
# needed). A quick example of specialized use is '--warn=^<100 --crit=>200'
# which will cause warning alert if value is < 100 and critical alert
# if its greater then 200.
#
# =================================== TODO ===================================
#
# 1. [0.3 DONE] Update to my latest format & code for parsing warning & critical
# parameters so they can be of the form "<value", ">value" as well
# as "~". Note that in this version the "<value" is specified as
# "-value" as with check_jboss plugin - but this will be going away!
# 2. Add support for storing values in some file so as to allow to check
# on rate of change rather then just actual value
# 3. As an option instead of using "twiddle" the data is retrieved
# from JBoss HTTP status/config data.
# 4. Add full "help" output in the "check_help" function
# 5. [0.2 DONE] Need to change how twiddle its called so that pid of the remote
# 6. [0.31 DONE] Added -S parameter to specify JMX service instead of type
# shell is kept and that process can be killed during timeout (otherise
# it maybe left hanging and become a zombie).
