Calling an from my own applocation

[Klaus <kl...@vommond.de>]

Hi,

 

I have a problem calling ant from my own application. As lonag as I just
call the standard ant task, there is no problem. But if I want to use some
external tasks, like jaxb etc. ant craches while execution. The entire
application is packed into one single jar file. This jar-file contains the
necessary libs. If a check the properties of the ant project in my code, I
see that "java.class.path" is set to myApplication.jar. If tried to change
this properties, but it did'nt change anything!

 

Here is my code:

 

Project ant = new Project();

ProjectHelper helper = new ProjectHelperImpl();

ant.init();

helper.parse(ant, new File("build.xml")); 

ant.executeTarget("generate-hybrid-config");
