[jdom-interest] Please Help!

[Ian Lea]

I created an XML file for your data, stuck it on my local file system,
hardcoded the full path into your source files, added a couple of
System.out.println() calls to display xmlUrl and passedId in
listData(), compiled your source and tried TestClass and the servlet
in Tomcat and after some messing around to get the right data in the
XML file it works. XML file attached.


A couple of suggestions as to why it isn't working for you:

  Are you sure the servlet and TestClass are using the same
  version of scheduler_config.xml?  I hard-coded the path
  as /tmp/scheduler_config.xml.

  In your source you refer to both ftp.la.viacom.com and
  ftp.dc.viacom.com.  I added both to the XML file.

  I'm using Tomcat on linux, you are using Allaire JRun on MSWin.



I don't think these are related to your problem but I might make a few
other suggestions too:

  . Lose the quotes and/or java.net.URLEncoder.encode() the
    data in your redirect URL query string.

  . Be consistent in naming - pollingfrequency or pollfreq or ???

  . listData seems to stick data in a Vector if is present in
    the XML file, and its caller then takes stuff out of the
    Vector by position.  Looks dodgy unless you can be 100%
    confident that the XML will always contain all elements.
    I might use a HashMap, or pass back the matching JDOM Element
    and extract the values directly.  Or something.


Good luck.
