Hi All,

I need to import many files sequentially , should I create a new graph for each file? or I can use the same graph ? please I need details.  
thanks,

// create Graph + Node + 2 connections (edges)  
TransformationGraph graph = new TransformationGraph();  
Edge inEdge=new Edge(“InEdge”,metadataIn);  
Edge outEdge=new Edge(“OutEdge”,metadataIn);

Node nodeRead=new DataReader(“DataParser”,arg[DATA\_FILE\_PROPERTY\_INDEX]);  
String sortKeys=arg[KEY\_PROPERTY\_INDEX].split(“,”);  
Node nodeSort=new ExtSort(“Sorter”,sortKeys, true);  
Node nodeWrite=new DataWriter(“DataWriter”,arg[OUTPUT\_FILE\_PROPERTY\_INDEX],“UTF-8”,false);

// assign ports (input & output)  
nodeRead.addOutputPort(0,inEdge);  
nodeSort.addInputPort(0,inEdge);  
nodeSort.addOutputPort(0,outEdge);  
nodeWrite.addInputPort(0,outEdge);

// add Edges & Nodes & Phases to graph  
try {  
graph.addPhase(\_PHASE\_1);  
\_PHASE\_1.addNode(nodeRead);  
\_PHASE\_1.addNode(nodeSort);  
graph.addPhase(\_PHASE\_2);  
\_PHASE\_2.addNode(nodeWrite);  
graph.addEdge(inEdge);  
graph.addEdge(outEdge);  
}catch (GraphConfigurationException ex){  
ex.printStackTrace();  
}

//prepare runtime parameters - JMX is turned off  
GraphRuntimeContext runtimeContext = new GraphRuntimeContext();  
runtimeContext.setUseJMX(false);

Future result;  
try{  
result = runGraph.executeGraph(graph, runtimeContext);  
while (result.isDone()) {;}  
if (!result.get().equals(Result.FINISHED\_OK)){  
System.out.println(“Failed graph execution!\n”);  
return;  
}  
}catch (Exception e) {  
System.out.println(“Failed graph execution!\n” + e.getMessage());  
return;  
}

Hello,  
you can use wild cards in the file name for reading different files. See [fileURL](http://wiki.cloveretl.org/doku.php?id=components:readers#fileurl) for full information.
