<p>I guess I need to know what I need in the classpath (what jar) in order to execute WebSphere 6.1 ant tasks. If someone can provide an example that would be perfect.</p>

The Actual Websphere Ant tasks are defined in
```
wsanttasks.jar
```
.
A possible path for linux Systems is
```
/opt/IBM/WebSphere/AppServer/lib/wsanttasks.jar
```
However I doubt that you will be successfull just by including that, as I do remember trying it once and it failed because of dependecies.
However, it is not impossible to do it as
```
ws_ant
```
is just a wrapper script which adds
all the required classpaths and calls the inbuilt ant
. So if you have time to look into the
```
ws_ant
```
script you will be able to get all the required classpath's.
By the way is there any special reason why you want to avoid
```
ws_ant
```
, that will surely make your life simple.
