I am trying to build webservices from within Eclipse using Ant. For that I am using the weblogic 'servicegen' ant task. But I get the following error. ( I have included both weblogic.jar and webservices.jar in the ant path under windows>preferences>ant>runtime, but that doesn't work. The same build file however works from the command prompt). I have also included the build file and error message below.

Ant could not find the task or a class this task relies upon.
This is common and has a number of causes; the usual solutions are to read the manual pages then download and install needed JAR files, or fix the build file: - You have misspelt 'servicegen'. Fix: check your spelling. - The task needs an external JAR file to execute and this is not found at the right place in the classpath. Fix: check the documentation for dependencies. Fix: declare the task. - The task is an Ant optional task and the JAR file and/or libraries implementing the functionality were not found at the time you yourself built your installation of Ant from the Ant sources. Fix: Look in the ANT_HOME/lib for the 'ant-' JAR corresponding to the task and make sure it contains more than merely a META-INF/MANIFEST.MF. If all it contains is the manifest, then rebuild Ant with the needed libraries present in ${ant.home}/lib/optional/ , or alternatively, download a pre-built release version from apache.org - The build file was written for a later version of Ant Fix: upgrade to at least the latest release version of Ant - The task is not an Ant core or optional task and needs to be declared using <taskdef>. - You are attempting to use a task defined using <presetdef> or <macrodef> but have spelt wrong or not defined it at the point of use
Remember that for JAR files to be visible to Ant tasks implemented in ANT_HOME/lib, the files must be in the same directory or on the classpath
Please neither file bug reports on this problem, nor email the Ant mailing lists, until all of these causes have been explored, as this is not an Ant bug. Total time: 1 second
Go the solution to my problem.I added a taskdef to my build file. <taskdef name="servicegen" classname="weblogic.ant.taskdefs.webservices.servicegen.ServiceGenTask"/>
But the point that I still do not get is, how does the same build file ( without the taskdef) work from the command prompt ?
