Pass Files As Arguments

Question

I have several files and want to pass them as arguments to a Helper class for further processing. I put the public static void main (String arg[]) {} class and the Helper class in a package.
I got error messages "cannot resolve symbol" for:
1. variable XSLTransformHelper for if (!XSLTransformHelper.transform(xmlin, xslin, htmlout))
2. method close() for xmlin.close();
3. method close() for xslin.close();
4. method close() for htmlout.close();
I cannot spot the problems and my code can be seen below:
=====================================
package Transform;
import java.io.*;
public class XSLTransform {
public static void main(String[] args) throws Exception {
//Create a file object with the file name in the argument:
File xmlin = new File("c:/javaprj/RSS.xml");
File xslin = new File("c:/javaprj/RSS.xsl");
File htmlout = new File("c:/javaprj/RSS.html");
if (!XSLTransformHelper.transform(xmlin, xslin, htmlout))
System.err.println("Transformation failed");
else
try {
xmlin.close();
xslin.close();
htmlout.close();
catch(IOException e)
{System.out.println("closing file exception");}
=======================================================
=======================================================
package Transform;
import javax.xml.transform.*;
import javax.xml.transform.stream.StreamResult;
import javax.xml.transform.stream.StreamSource;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
public class XSLTransformHelper {
public static boolean transform(String xmlFilename, String xslFilename, String resultFilename) {
try {
TransformerFactory factory = TransformerFactory.newInstance();
Source xmlSource = new StreamSource(new FileInputStream(xmlFilename));
Source xslSource = new StreamSource(new FileInputStream(xslFilename));
Transformer transformer = factory.newTransformer(xslSource);
Result result = new StreamResult(new FileOutputStream(resultFilename));
transformer.transform(xmlSource, result);
return true;
} catch (TransformerFactoryConfigurationError transformerFactoryConfigurationError) {
transformerFactoryConfigurationError.printStackTrace();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (TransformerException e) {
e.printStackTrace();
return false;

I have several files and want to pass them as
arguments to a Helper class for further processing. I
put the public static void main (String arg[]) {}
class and the Helper class in a package.
I got error messages "cannot resolve symbol" for:
1. variable XSLTransformHelper for if
(!XSLTransformHelper.transform(xmlin, xslin,
htmlout))
2. method close() for xmlin.close();
3. method close() for xslin.close();
4. method close() for htmlout.close();
I cannot spot the problems and my code can be seen
below:
=====================================
package Transform;
import java.io.*;
public class XSLTransform {
public static void main(String[] args) throws
ws Exception {
//Create a file object with the file name in the
n the argument:
File xmlin = new File("c:/javaprj/RSS.xml");
File xslin = new File("c:/javaprj/RSS.xsl");
File htmlout = new File("c:/javaprj/RSS.html");
if (!XSLTransformHelper.transform(xmlin, xslin,
slin, htmlout))
System.err.println("Transformation failed");
else
try {
xmlin.close();
xslin.close();
htmlout.close();
catch(IOException e)
{System.out.println("closing file
losing file exception");}
=======================================================
=======================================================
package Transform;
import javax.xml.transform.*;
import javax.xml.transform.stream.StreamResult;
import javax.xml.transform.stream.StreamSource;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
public class XSLTransformHelper {
public static boolean transform(String
ing xmlFilename, String xslFilename, String
resultFilename) {
try {
TransformerFactory factory =
y factory = TransformerFactory.newInstance();
Source xmlSource = new StreamSource(new
mSource(new FileInputStream(xmlFilename));
Source xslSource = new StreamSource(new
mSource(new FileInputStream(xslFilename));
Transformer transformer =
ansformer = factory.newTransformer(xslSource);
Result result = new StreamResult(new
mResult(new FileOutputStream(resultFilename));
transformer.transform(xmlSource, result);
return true;
} catch (TransformerFactoryConfigurationError
onError transformerFactoryConfigurationError) {
transformerFactoryConfigurationError.printStackTrace()
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (TransformerException e) {
e.printStackTrace();
return false;
======================================================I observe that you pass Files as arguments of the method transform while this method is expecting Strings!!!!
