Hi,

While using a external partition class to partition node, i am getting this error.

java.lang.RuntimeException: Can’t create object of type PARTITION with reason: PARTITION:PARTITION0:Can’t find specified partition function class: PARTITION0

I have created seperate jar file for this partition class and added to build path in eclipse. But still it is throwing this exception.

Hi, are you running graph from command line or from GUI? You only need to have your class in classpath.

Hi,

I found the problem. Problem is in clover.etl source code.

In partition.java, instead of creating partition function class using XML\_PARTITIONCLASS\_ATTRIBUTE it is creating using XML\_ID\_ATTRIBUTE in fromXML method.

if (xattribs.exists(XML\_PARTITIONCLASS\_ATTRIBUTE)) {//load class with partition function  
try {  
//TODO move creating function to init method  
partitionFce = **(PartitionFunction)Class.forName(xattribs.getString(XML\_ID\_ATTRIBUTE)).newInstance();**
