I just wanted the data. Sure I could have have just put in bogus values for them on the command line, but it just cluttered it up. One problem i have is with returned data that's a number with a decimal in it (like 'OK - Attribute get 'java.lang:type=OperatingSystem' - ProcessCpuLoad = 0.009808796275369524'). It returned a Bad Response because $num was null. I tried a different regex for it, but i'm not very good with regex. :D I ended up just doing a "split ' = ', $content" to get the number. -Tony > --------------------------------------------------------------------- > To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org > For additional commands, e-mail: users-h...@tomcat.apache.org > >
