onApplicationEvent

public void onApplicationEvent(org.springframework.context.ApplicationEvent event)

Specified by:

onApplicationEvent in interface org.springframework.context.ApplicationListener

main

public static void main(java.lang.String[] args)

The main routine for starting the deployment of a UIMA-AS instance. The args are either: 1 or more "paths" to Spring XML descriptors representing the information needed or some number of parameters, preceeded by a "-" sign. If the first arg doesn't start with a "-" it is presumed to be the first format. For the 2nd style, the arguments are: -saxonURL a-URL-to-the-saxon-jar usually starting with "file:", -xslt path-to-the-dd2spring.xsl file, -d path-to-UIMA-deployment-descriptor [-d path-to-another-dd ...] these arguments may be in any order) For the 3rd style, like #2 but with multiple dd-files following a single -dd Useful for calling from scripts.

Parameters:

args -
