Java Mapping
Hi all,
I have written a java mapping program which wil take the input value as CSV and convert that into XML of the target structure.
The structure is like
Source
<Root>
<Number>1</Number>
</Root>
<Root>
<Number>2</Number>
</Root>
<Root> <Number>3</Number>
</Root>
The Source is a CSV with delimiter as ";" source file 1;2;3
The Target Structure is
<Node>
<Value>1</Value>
<Value>2</Value>
<Value>3</Value>
</Node>
The program i have written is as follows:
public class TMapping implements StreamTransformation {
private Map map;
public void setParameter (Map param){
map = param;
}
public void execute(InputStream in, OutputStream out) throws StreamTransformationException {
try {
out.write("<?xml version ='1.0' encoding='UTF-8'?>".getBytes());
out.write(" ".getBytes" target="_blank"> ".getBytes" target="_blank">http://www.infosys.com/sap/xi/projects/rt/n2">".getBytes());
out.write("<Node>".getBytes());
String line = null;
BufferedReader bin = new BufferedReader(new InputStreamReader(in));
while((line = bin.readLine())!= null) {
String value = null;
char[] str = new char[100];
str = line.toCharArray();
int s1 = 0;
int s2 = 0;
String[] Data = new String[10];
for(int i=0;i<line.length();i++)
{
if(str<i>==';')
{
Data[s1] = line.substring(s2,i);
s1=s1+1;
s2=i+1;
}
if(i== line.length()-1)
{
Data[s1] = line.substring(s2,i+1);
for(int j=0; j<3; j++) {
String data = Data[j];
out.write(("<Value>"data"</Value>").getBytes());
}
}
}
}
out.write("</Node>".getBytes());
out.write("</ns0:MT_MappingTest_Target>".getBytes());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
I have excluded the imports:
I tried it using the main method and it gives a perfect out.xml file
i imported the same into XI and the error which is its showing is
"does not implement the required interface com.sap.aii.mapping.api.StreamTransformation"
when i have implemented the StreamTransformation interface
Can any one tell me how to implement the same
Rgds
