Hi Brian,
I just applied the patch you made according to the following steps:
cd apache-oodt-0.4-src/pushpull
patch -p0 < OODT-476.2012-07-25.txt
mvn clean
mvn install
cp target/cas-pushpull-0.4.jar ~/oodt/cas-pushpull/lib/
After I got a new cas-pushpull-0.4.jar,
yhkang@yunhee-kisti:~/oodt/cas-pushpull/lib$ ls -l cas-pushpull-0.4.jar
-rw-r--r-- 1 yhkang yhkang 422602 2012-07-26 16:58 cas-pushpull-0.4.jar
I ran the script pushpull.
But the same error message was generated:
INFO: Successfully connected to ftp://l4ftl01.larc.nasa.gov with
protocol 'org.apache.oodt.cas.protocol.ftp.CommonsNetFtpProtocol' and
username 'anonymous'

Could you check a class name for handling ftp protocol ?
I used "CommonsNetFtpProtocolFactory.class" in the jar named
"cas-protocol-ftp-0.4.jar".
The class file was described in the file ProtocolFactoryInfo.xml as follows:
<protocol type="ftp">
....
<!-- cas-protocol-ftp-0.4.jar -->
<!--protocolFactory
class="org.apache.oodt.cas.protocol.ftp.CommonsNetFtpClientFactory"/-->
<protocolFactory
class="org.apache.oodt.cas.protocol.ftp.CommonsNetFtpProtocolFactory"/>
</protocol>
Thanks,
Yunhee
