I'm having a problem in running my process in a Java Application

Hi I'm having errors/warnings with my Java app. Any help would be appreciated.

Here is my code in Netbeans:
RepositoryLocation pLoc = new RepositoryLocation(process);
ProcessEntry pEntry = (ProcessEntry) pLoc.locateEntry();
String processXML = pEntry.retrieveXML();
com.rapidminer.Process myProcess = new com.rapidminer.Process(processXML);
myProcess.setProcessLocation(new RepositoryProcessLocation(pLoc));

Operator myOperator = myProcess.getOperator("Read Excel - New Data");
RepositoryLocation loc = new RepositoryLocation(upload);
IOObjectEntry entry = (IOObjectEntry) loc.locateEntry();
IOObject myIOObject;
myIOObject= entry.retrieveData(null);
myOperator.setParameter(RepositorySource.PARAMETER_REPOSITORY_ENTRY, upload);

IOContainer ioInput = new IOContainer(new IOObject[] {myIOObject});
IOContainer ioResult = myProcess.run(ioInput);

if (ioResult.getElementAt(0) instanceof IOObject) {
ExampleSet resultSet = (ExampleSet)ioResult.getElementAt(0);
jLabelStatus.setText(resultSet.toString());
Here is the XML of my process in RapidMiner:
