Hello,

 

I was creating an ANT-task that is using derby.jar as jdbc driver.

I put derby.jar in the front of the classpath of my task.

But every time I tried to reload sth. into my derby database it failed: sth. like \
"JDBC driver not found"

 

Yesterday I found a workaround for my problem:

I moved derby.jar into the classpath of ANT.

And that worked.

 

My question is Why does it nor work with derby.jar in my tasks classpath, because \
this is the solution I prefer?

(As far as I know, ANT creates a new classloader for the new task. It seems that the \
derby stuff is only searched in ANTs parent classloader)

 

Yours

Jürgen
