I have jpos.xml generated, but I have no idea where to put it into the project..

Answer 1

the file can be place any where but the root is the best place to start. /* If you want to place the jpos.xml file elsewhere on your local file system then uncomment the following line and specify the full path to jpos.xml.

 If you want to place the jpos.xml file on a webserver for access over the internet then uncomment
 the second System.setProperty line below and specify the full URL to jpos.xml.
 */

System.setProperty( JposPropertiesConst.JPOS_POPULATOR_FILE_PROP_NAME, "jpos.xml");

System.setProperty(JposPropertiesConst.JPOS_POPULATOR_FILE_URL_PROP_NAME, "http://some-where-remote.com/jpos.xml");

error try adding this

  System.setProperty("jpos.loader.serviceManagerClass", "jpos.loader.simple.SimpleServiceManager");
  System.setProperty("jpos.config.populatorFile", "jposxml.cfg");
  System.setProperty("jpos.util.tracing.TurnOnNamedTracers", "JposServiceLoader,SimpleEntryRegistry,SimpleRegPopulator,XercesRegPopulator");
  System.setProperty("jpos.util.tracing.TurnOnAllNamedTracers", "ON");
