Hello Achim,
Thanks a lot for the reply. I modified my code to almost similar to your
test case. still i'm faced with the same error.
Please can you let me know if you have any suggestions.
arangoDriver.startBatchMode();;
for(String line : lines)
{
String[] data = line.split(",");
BaseDocument device = new BaseDocument();BaseDocument
phyAddress = new BaseDocument(); BaseDocument conn = new BaseDocument();
device.setDocumentKey(data[0]);device.addAttribute("device_id",data[0]);
phyAddress.addAttribute("address",data[1]);
conn.addAttribute("weight",0);
final DocumentEntity<BaseDocument> fromHandle =
arangoDriver.graphCreateVertex("testGraph", "DeviceId", device, null);
final DocumentEntity<BaseDocument> toHandle =
arangoDriver.graphCreateVertex("testGraph", "PhysicalLocation", phyAddress,
null);
arangoDriver.graphCreateEdge("testGraph",
"DeviceId_PhysicalLocation", null,fromHandle.getDocumentHandle(),
toHandle.getDocumentHandle(), null, null);
}
arangoDriver.executeBatch();
Thanks,
Praveen
