Passing Files in Web Services

[feda alshahwan]

I would like to implement a web service that reads two files one in xml and other in xslt and do the transformation then output a third transformed file How can I do that ? My problem is how to pass files and output it?

[Ulf Dittmer]

Tranferring files over SOAP WS is done by the "SOAP with Attachments" API, a.k.a SAAJ. Start by reading Transferring files over a web service and Sending SOAP attachments using SAAJ.

What is the method required to pass an xml file and xslt then the output willl be xhtml using Eclipse platform my code is as follows but it is not working

   package chap5;
import java.io.*;
 
public class XSLTTransform 
{
	public static OutputStream xslttransform(File xmlFileName, File xslFileName)
	{
		File xmlFile = xmlFileName;
        File xsltFile =xslFileName;
        javax.xml.transform.Source xmlSource =
            new javax.xml.transform.stream.StreamSource(xmlFile);
    javax.xml.transform.Source xsltSource =
            new javax.xml.transform.stream.StreamSource(xsltFile);
    javax.xml.transform.Result result =
            new javax.xml.transform.stream.StreamResult(System.out);

    // create an instance of TransformerFactory
    javax.xml.transform.TransformerFactory transFact =
            javax.xml.transform.TransformerFactory.newInstance(  );

    javax.xml.transform.Transformer trans =
            transFact.newTransformer(xsltSource);

    trans.transform(xmlSource, result);
    return result;
	}
}

it is not working

What does this mean? Are there any error messages? if so, post the stack traces.

I am getting the following error:

Why are you doing this:

 /XSLTTransform/WEB-INF/classes/chap5/XSLTTransform.java   

Java is not a scripting language, it requires a compiled class.

Get something working OUTSIDE the server environment first, debugging is hard enough without complications.

A URI isn't useful unless the service can retrieve the files itself - which in many cases it can't unless special arrangements have been made (e.g. file is stored on an anonymously accessible FTP site). So sending the files to the web service is the usual solution.

The web service "reading" the files isn't practical - you are going to have to pass them to it - that is provide the content of the files in the web service request. Both the data XML and the XSLT file are pure XML - the output of an XSLT transformation could be anything text based. Now when transferring the content of arbitrary types of files usually some kind of attachment technology is involved as Ulf has already mentioned. Another more recent but not that widely supported standard is MTOM (JAX-WS: Binary Attachments (MTOM)) - however no standard is universally supported, so sometimes it makes sense to do the encoding/decoding yourself (Send binary data without using attachments).

However in your case the complexity of attachments isn't necessary as the both inputs are XML and the output is plain text. Plain SOAP can handle XML and plain text.

What is the method required to pass an xml file and xslt then the output will be xhtml

This means that we can constrain the solution even further because the output is also XML.

A "simple" example of a JAX-WS (as included in the plain JDK 1.6) service that can handle that is shown below:

        try {

            /* root element is replaced by transformResponse Document's
               output element - so wrap original root in order to preserve it
             */
            result = domUtil.wrapDocumentRootElement( resultDoc,"","resultRoot" );
          
        } catch (DomUtilException due) {
            // log due.printStackTrace();
            throw new Xslt2XmlServiceFault( "Transformation failed" );
        }

        return (Object) result;

    private void initialize() {
        if(domUtil != null) return;
          
        domUtil = new DomUtil();
    }
}

(This service will not work if the XSLT transform doesn't produce well-formed XML)

The one thing that is peculiar about the WebMethod is that it accepts java.lang.Object parameters. A web method cannot accept org.w3c.dom.Document objects because the RequestWrapper is always one single XML document. So multiple "XML Documents" can only be wrapped into a single XML Document by transferring each document's "document root org.w3c.dom.Element" into the wrapping document. JAX-WS strips off the transformRequest RequestWrapper and simply hands you the org.w3c.dom.Element objects that correspond to your method parameters. Now JAXB can't handle org.w3c.dom.Element because it can only marshal and unmarshal classes, not interfaces. However if you hand it the org.w3c.dom.Element objects as java.lang.Object objects it "goes that the extra mile" and figures out that it can simply use the raw XML. You still need a class to do the DOM related grunt work.

Something still has to run the web service

package com.coderanch.jaxws.passxml.provider;

import javax.xml.ws.Endpoint;

class Main {
    public static void main(String[] args) {

        Endpoint.publish(
            "http://localhost:8080/wsdemo/xslt2xml",
             new Xslt2XmlImpl()
        );
    }

}

Now you have enough for your web service. Compile it:
javac -d . DomUtil.java
javac -d . Xslt2XmlImpl.java
javac -d . Main.java
wsgen -cp . -s src com.coderanch.jaxws.passxml.provider.Xslt2XmlImpl

Run it:
java com.coderanch.jaxws.passxml.provider.Main

You should now be able to access the following URIs with your browser:
http://localhost:8080/wsdemo/xslt2xml?wsdl
http://localhost:8080/wsdemo/xslt2xml?xsd=1
http://localhost:8080/wsdemo/xslt2xml?xsd=2

There is a feature in the schema that deserves some attention. For example:
<xs:element name="data" type="xs:anyType" minOccurs="0"/>

{http://www.w3.org/2001/XMLSchema}anyType allows any well-formed XML fragment at that point in the XML document. In this particular case "data" is the XML fragment that holds the XML data for your transformation. However the root element that you hand JAX-WS will become the "data" element in the transformRequest RequestWrapper. In this case we want to preserve the original element root so we have to wrap the original root in another element that can then become the "data" element in transformRequest. On the provider side we receive the "data" element which then has to be stripped off to expose the original root element. The same applies to the "style" element of the transformRequest RequestWrapper and the "output" element of the transformResponse ResponseWrapper.

Now it's time to generate the consumer side artifacts (while the service is running):
wsimport -p com.coderanch.jaxws.passxml.consumer -s src http://localhost:8080/wsdemo/xslt2xml?wsdl

Once those are generated we can use them in the consumer:

package com.coderanch.jaxws.passxml.consumer;

Dump the IDE - it is not helping you, it is setting up barriers against you.

Put the files into a single directory and work from the console command line ...

The "required commands" are given in between the source code listings.

Apparently not to the point that you can diagnose and correct any problems that the IDE environment or application server "magic" may introduce.
IDEs are great tools to automate tedious and mundane activities and tasks for developers who already know and understand the intricacies of the development and deployment process (and have a good knowledge of the IDEs configuration options). However all too often people take the attitude that "if the IDE can do it, I don't need to know how it works" which will ultimately get them into trouble because there will always be situations where the generic "IDE logic/scripting" isn't quite up to the task and will fail. When learning new technologies it's usually best to remove any variables that introduce technological complexities - and IDEs and application servers introduce technological complexities. Dropping down to the command line and command line tools gives you full control and it also forces you to understand what is going on.

The above example simply works with the com.sun.net.httpserver.HttpServer that ships with the 1.6 JDK - not even a servlet container. Once you get that working you may want to find out how to get JAX-WS working on a plain Tomcat installation
JAX-WS 2.0 Samples on Tomcat 5.5.x
Running JAX-WS Samples with Tomcat 6.x
preferably by setting it up manually. Then try to get the Xslt2Xml service running on Tomcat - again, preferably by setting it up manually.
After that you may want to contemplate trying it on an IDE (after you have convinced yourself that it can actually work with your previous experiments). Always start simply and introduce elements with complexities (even if this complexity occurs behind the scenes) gradually and in small increments.

Do you have JDK/JRE 1.6 installed? That is, try:
>java -version
java version "1.6.0_11"
Java(TM) SE Runtime Environment (build 1.6.0_11-b03)
Java HotSpot(TM) Client VM (build 11.0-b16, mixed mode, sharing)


Do you have the JAVA_HOME environment variable set? Example:
>set java_home
java_home=C:\opt\Java\jdk1.6.0_11


You seem to have "a" java version in your PATH environment variable. Example:
>set PATH
Path=C:\opt\Java\jdk1.6.0_11\bin;C:\opt\maven2\bin;C:\Windows\system32;... blah blah blah


Do you have your CLASSPATH environment variable set? Example:
>set CLASSPATH
CLASSPATH=.;C:\opt\log\lib\log4j-1.2.15.jar;C:\opt\log\lib\slf4j-api-1.5.6.jar;C:\opt\log\lib\slf4j-log4j12-1.5.6.jar

(the C:\opt\log\lib\ jar archives aren't necessary but serve as examples of additional, non-JDK libraries)

This is because I am using Eclipse I didnot set the Dos for web services How can I do that?

[Ulf Dittmer]

So you have two JREs installed, one for Java 5 and one for Java 6. You need to use Java 6 for the javax.jws.* classes.

I'd start by changing the JAVA_HOME and PATH variables to use the Java 6 installation.

What are the class files doing under the src directory? Do you mean source files?

create C:\Documents and Settings\Welcome\workspace\transform\src\com\coderanch\jaxws\passxml\DomUtil.java

create C:\Documents and Settings\Welcome\workspace\transform\src\com\coderanch\jaxws\passxml\provider\Xslt2XmlImpl.java

create C:\Documents and Settings\Welcome\workspace\transform\src\com\coderanch\jaxws\passxml\provider\Main.java

Now on the command line start by changing to the correct directory:
cd "C:\Documents and Settings\Welcome\workspace\transform"
javac -d . src\com\coderanch\jaxws\passxml\DomUtil.java
javac -d . src\com\coderanch\jaxws\passxml\provider\Xslt2XmlImpl.java
javac -d . src\com\coderanch\jaxws\passxml\provider\Main.java
wsgen -cp . -s src com.coderanch.jaxws.passxml.provider.Xslt2XmlImpl

javac will create the following class files:
C:\Documents and Settings\Welcome\workspace\transform\com\coderanch\jaxws\passxml\DomUtil.class
C:\Documents and Settings\Welcome\workspace\transform\com\coderanch\jaxws\passxml\DomUtil$DomUtilException.class

C:\Documents and Settings\Welcome\workspace\transform\com\coderanch\jaxws\passxml\provider\Main.class

wsgen will create the following source files
C:\Documents and Settings\Welcome\workspace\transform\src\com\coderanch\jaxws\passxml\provider\TransformRequest.java
C:\Documents and Settings\Welcome\workspace\transform\src\com\coderanch\jaxws\passxml\provider\TransformResponse.java

C:\Documents and Settings\Welcome\workspace\transform\com\coderanch\jaxws\passxml\provider\TransformRequest.class
C:\Documents and Settings\Welcome\workspace\transform\com\coderanch\jaxws\passxml\provider\TransformResponse.class

Now you should be able to run the service:
cd "C:\Documents and Settings\Welcome\workspace\transform"
java com.coderanch.jaxws.passxml.provider.Main


Once the service is running (and you successfully accessed its WSDL and XSDs) run
cd "C:\Documents and Settings\Welcome\workspace\transform"
wsimport -p com.coderanch.jaxws.passxml.consumer -s src http://localhost:8080/wsdemo/xslt2xml?wsdl

Compile the consumer:

cd "C:\Documents and Settings\Welcome\workspace\transform"
java -cp . com.coderanch.jaxws.passxml.consumer.Xslt2XmlSoapClient cdcatalog.xml cdcatalog.xsl

That means its working i.e. the com.sun.net.httpserver.HttpServer is hosting your web service.
At this point you should be able to see the WSDL and XSD in a browser.
To proceed with the consumer you will have to open a second command line console window.

To eventually terminate the com.sun.net.httpserver.HttpServer in the first window use Ctrl-C and respond with 'Y'.

[feda alshahwan]

i cannot see the wsdl in a browser , Do I have to start tomcat before or it is automatically started like eclipse.

java com.coderanch.jaxws.passxml.provider.Main is running com.sun.net.httpserver.HttpServer

That XSLT does'nt produce well formed XML - so the service fails as I remarked above. A more general version would return a String result not an XML Document.

The XSLT identity transform works:

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    version="1.0">

   </xsl:template>
</xsl:stylesheet> 

[Peer Reynders]

[Fatal Error] xsltFile.xsl:8:6: The processing instruction target matching "[xX][mM][lL]" is not allowed.

Also, you are getting that error because you have whitespace in front of the <?xml version="1.0" encoding="ISO-8859-1"?> XML prolog.
Get rid of the whitespace - otherwise the XSLT and XML file isn't a well formed XML document.
