taskdef class ... not found

["Huang, Daniel" <dh...@InterAdNet.com>]

Hi there,

I just installed Ant1.2 under JDK1.3, JAXP 1.0.1, and Window NT 4.0. I
created my own taskdef with Ant_sqlj.java. I could not run ant when I put my
java class in a package: com.myDomain.myAntTask. I have error:

E:\tmp\build.xml:4: taskdef class com.myDomain.myAntTask.Ant_sqlj cannot be
found

I could see the class when I run

	javap com.myDomain.myAntTask.Ant_sqlj 

However, when I removed the package name, I could run ant.

Any help appreciated.

What happens if you enter javap org.apache.tools.ant.Task?
How are you starting your Ant?
And how do you define you task (cut the <taskdef..>-part from your build.xml
and post it here)

Looks like for some reason Ant has problems with your classpath...
