Simon RichardsSubject: SQL Table to XML Convert error when running Java code

I wonder if anyone can help me with the following.

I'm new to Stylus Studio and I'm trying to export a SQL Server database table to XML using a style sheet and an XML schema to define the XML output.

The export works fine within the Stylus Studio IDE, but I have generated the Java code, tried to run it and I'm getting an error.

When I step through the Java code, it appears as though the code is looking for a [file?] called:

ConverterResolver.java

It cannot find this and pops up a "Browse For Folder" dialogue box.

The Java code it's trying failing with is as follows:
************************************************************

package SimonPackage;

import com.ddtek.xmlconverter.ConverterFactory;
import com.ddtek.xmlconverter.ConverterResolver;
import java.io.IOException;
import java.io.InputStream;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.stream.StreamResult;
import javax.xml.transform.stream.StreamSource;

/** Run an XSLT
* This class requires the following items in the classpath.
* C:/TMP
* C:/Program Files/Stylus Studio 2007 XML Enterprise Suite Release 2/bin/XMLConverters.jar
*/

public class TestStyleSheet {

public static void main(String[] args) throws Exception {

ConverterResolver resolver = new ConverterFactory().newResolver();

String inputUrl = "xquery:///jdbc:xquery:sqlserver://testdev;schema=dbo;table=address;user=testdevbatch;password=0433356545345A1855;xmlforest=true;DatabaseName=testdev;urltype=.xml";
InputStream inStream = null;
String outputUrl = "file:///c:/TMP/OutputAddressTest.xml";
String xsltUrl = "file:///c:/TMP/TestStyleSheet.xsl";


try {
TransformerFactory tFactory = TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer(new StreamSource(xsltUrl));
transformer.setURIResolver(resolver);

StreamSource source = (StreamSource)resolver.resolve(inputUrl, null);
if (source==null) throw new IOException("Unable to resolve " + inputUrl);
inStream = source.getInputStream();

System.out.println();
System.out.println("XSLT starting.");
transformer.transform(source,
new StreamResult(outputUrl));
System.out.println("XSLT finished.");
inStream.close();
} finally {
if (inStream!=null) inStream.close();
}
}
}
************************************************************


The error that is being produced is as follows:
*************************************************************
C:\Program Files\Java\jre1.6.0_03\bin\java.exe -classpath C:\TMP;C:\PROGRA~1\STYLUS~1\bin\XMLCON~1.JAR SimonPackage.TestStyleSheet
Exception in thread "main" java.io.IOException: Unable to resolve xquery:///jdbc:xquery:sqlserver://testdev;schema=dbo;table=address;user=testdevbatch;password=0433356545345A1855;xmlforest=true;DatabaseName=testdev;urltype=.xml
at SimonPackage.TestStyleSheet.main(TestStyleSheet.java:37)
*************************************************************

Within the Stylus Studio environment, I have added the following ClassPaths:

* C:/TMP
* C:/Program Files/Stylus Studio 2007 XML Enterprise Suite Release 2/bin/XMLConverters.jar


I have attached my java files which may be of help to someone more technically minded than me.

Can anyone please help me shed any light on this problem?

With thanks

Hi Simon,

Support for xquery: has been discontinued, you will need to switch to XQuery using the DataDirect XQuery processor in order to export SQL to XML.

Hope this helps

Thanks for your reply.

The default installation of Stylus Studio appears to be set to use DataDirectXQuery Processor (Tools | Options | XQuery Processor Settings). I certainly have not changed this.

I have just installed the latest build of the software - 894m. This has not solved the problem. Instead it has made it worse. I am now getting the following error message when trying to compile the Java code:

Classpath:"C:\TMP";"C:\Program Files\Stylus Studio 2007 XML Enterprise Suite Release 2\bin\XMLConverters.jar"
Compiling...
TestStyleSheet.java
c:\TMP\AddressPackage\TestStyleSheet.java:6: cannot access java.io.IOException
bad class file: C:\Program Files\Java\jre1.6.0_03\lib\rt.jar(java/io/IOException.class)
class file has wrong version 49.0, should be 48.0
Please remove or make sure it appears in the correct subdirectory of the classpath.
import java.io.IOException;

I would be most grateful if you could advise as to the best way to proceed with this.

Much appreciated.

Hi Simon,
which JDK are you using to compile? Could you post a screen shot of the Java Virtual Machine page that is in the Tools | Option dialog?

Thanks,
Alberto

Hi Simon,

You have inconsistent version of JRE and JDK. Select the JRE 1.4.x then re-start Stylus Studio.

Hope this helps

Thanks for your second reply.

I've now changed the JRE version to 1.4 and it has compiled correctly.

Unfortunately I am still left with the original problem (on the basis that I haven't actually changed anything yet).

at AddressPackage.TestStyleSheet.main(TestStyleSheet.java:37)
Exception in thread "main"
******************************************************

I refer to your previous answer:
"Support for xquery: has been discontinued, you will need to switch to XQuery using the DataDirect XQuery processor in order to export SQL to XML", but it would appear as though I am using the DataDirect XQuery processor as you suggest.

I have attached a screen shot of the options settings. I would be most grateful if you could cast your eye over these and see if anything looks wrong.

Many thanks in advance.

Simon,

When I said "switch to XQuery" what I meant was that you will need to translate your XSLT "file:///c:/TMP/TestStyleSheet.xsl" into XQuery.

What you have done was simpling changing the default XQuery processor.

If you like you can send TestStyleSheet.xsl to stylus-field-report@progress.com and we will help you to convert it to XQuery.

DataDirect XQuery is far more powerful to manipulate relational data.
see the video tutorial at http://www.xquery.com/videos/datadirectxquery/ddxq1a.html


Hope this helps

Thanks for your prompt response.

I will indeed take a look at the on-line tutorial video and send a message to support if required.

Thanks for your assistance.
