jboss-as-7.1.1.Final and fop (classpath)

[schum-hacker]

Hello,

I use fop 0.95 and jsf 1.2. with netbeans 6.9.1 like ide.

The fop librairies are added in the WAR project but in the file, there are in the EAR not in the WAR.

On jboss 5, all is ok, fop works fine.

On jboss 7, i have a problem of classpath , the EAR is the same with jboss 5 or 7.

The stacktrace:

please help

Thanks !!!

Those are just warnings (AS7 is more pedantic). If you open up the jar files mentioned and clean out the classpath-entries in their manifest files, the warnings should go away.

[schum-hacker]

it's more than just warning.

When i call the servlet with fop:

line 122:   xslfoTransformer.transform(new StreamSource(xmlFile), res);

[nickarls]

I don't think it's related. What happens at GeneratePdf.java:122? What field is referenced?

[schum-hacker]

            File xmlFile;

            StreamSource transformSource;

               xmlFile = messageService.buildCC313AFile(ens);

               // creation of transform source

              transformSource = new StreamSource(Thread.currentThread().getContextClassLoader().getResourceAsStream("../../resources/xsl/PDFmcustoms_313.xsl"));

            // create an instance of fop factory

            FopFactory fopFactory = FopFactory.newInstance();

            // a user agent is needed for transformation

            FOUserAgent foUserAgent = fopFactory.newFOUserAgent();

            // to store output

            ByteArrayOutputStream outStream = new ByteArrayOutputStream();

            Transformer xslfoTransformer = getTransformer(transformSource);

            // Construct fop with desired output format

            Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF, foUserAgent, outStream);

            // Resulting SAX events (the generated FO) must be piped through to FOP

            Result res = new SAXResult(fop.getDefaultHandler());

            // Start XSLT transformation and FOP processing

            // everything will happen here.

            xslfoTransformer.transform(new StreamSource(xmlFile), res);

the pb is here:   xslfoTransformer.transform(new StreamSource(xmlFile), res);

can i have a pb with my url "../../resources/xsl/PDFmcustoms_313.xsl" but , it's works fine in jboss 5

[sfcoy]

JBoss 5 and earlier would allow you to get away with all sorts of classpath stuff that was not very spec compliant and therefore not very portable either.

Where exactly in your deployment have you been placing PDFmcustoms_313.xsl?

It looks like it's probably external to your deployment. If that's the case and you want to maintain that arrangement then have a look at How to put an external file in the classpath.

[schum-hacker]

in my project McustomsWeb\web\resources\xsl\PDFmcustoms_313.xsl

xsl url: http://localhost:8080/McustomsWeb/resources/xsl/PDFmcustoms_313.xsl

servlet url: http://localhost:8080/McustomsWeb/GeneratePdf

[sfcoy]

The correct way to access the XSL resource in this case is to use javax.servlet.ServletContext.getResourceAsStream(java.lang.String).

If you need a reference to pass around or stash then use javax.servlet.ServletContext.getResource(java.lang.String) and java.net.URL.openStream().

Alternatively, move it to WEB-INF/classes and access it using the TCCL as you were above (without the "../../").

[schum-hacker]

I use a string:

transformSource = new StreamSource(Thread.currentThread().getContextClassLoader().getResourceAsStream("../../resources/xsl/PDFmcustoms_313.xsl"));

so i'm a little confused on the way to follow to correct my pb ...

in my project McustomsWeb\src\java\fr\mgi\mcustomsweb\ics\servlet\GeneratePdf.java

i try absolute path:

transformSource = new StreamSource(Thread.currentThread().getContextClassLoader().getResourceAsStream("http://localhost:8080/McustomsWeb/resources/xsl/PDFmcustoms_313.xsl"));

same error

[sfcoy]

{code}McustomsWeb/resources/xsl/PDFmcustoms_313.xsl{code}

is not on any classpath. The fact that you could access it on the classpath in JBoss 5 was a happy accident that was never portable.

Therefore, you have two choices:

1. access it as a web resource from your servlet context
2. move it so that it's available on the classpath (into WEB-INF/classes) and access it the same way that you are now, but removing the "../../" from the path

[schum-hacker]

thanks

it works fine if:

i move PDFmcustoms_313.xsl in the directory McustomsWeb\src\java

transformSource = new StreamSource(Thread.currentThread().getContextClassLoader().getResourceAsStream("PDFmcustoms_313.xsl"));

I'd like to keep my file PDFmcustoms_313.xsl in

McustomsWeb\web\resources\xsl\PDFmcustoms_313.xsl

but in this case  in don't found the string to use in getResourceAsStream(?)

[sfcoy]

If you leave the file where it is then it will not be visible on any classpath. You have to use option 1 above. Click on the links in my original response to find out more.

Having said that, do you really want this XSL to be accessible from a web browser?

[schum-hacker]

i haven't this need .

So i stay like this.

thanks very much !!!!!!!
