Subject Re: New Task and Classpath
Date Thu, 28 Aug 2003 20:08:50 GMT
I used org.apache.tools.ant.taskdefs because I intend to put this task
like standard ant task. But this is not a problem.

The problem is I call a java class into the new ant task. If you look the
execute() method it call iniciarGeracao() that instantiate
GeradorRelatorio() class. In this case, during the execution the jars
files is not found. In spite of I have set the classpath.
