using file-serializer --> [No error message provided.]

Hi,

I tried to copy a file specified with a URL from one location to the other, by using the URL generator and the File serializer.

here's my copy.xpl:

        <p:param name="data" type="output"/>
       
       
        <p:processor name="<b>oxf:url-generator">
                <p:input name="config">
                        <config>
                                <url>file:/c:/Temp/origin.xml</url>
                        </config>
                </p:input>
                <p:output name="data" id="<b>origin-data"/>
        </p:processor>
       
       
        <p:processor name="<b>oxf:file-serializer">
                <p:input name="config">
                        <config>
                                <directory>c:/Temp</directory>
                                <file>copy.xml</file>
                                <make-directories>true</make-directories>
                                <append>false</append>                       
                        </config>
                </p:input>
                <p:input name="data" href="<b>#origin-data"/>
                <p:output name="data" id="<b>sthToPreventError"  ref="data"/>
        </p:processor>

(As it maybe explicit I have added an extra output because "The processor output must be connected")

browing http://localhost:8080/newOrbeon/xforms-samplecopy/ according to <page path-info="/xforms-samplecopy/"  model="copy.xpl"/> , a java.lang.NullPointerException has Occurred with no messege.


Before this, I was refering logo.jpg & copy.jpg instead of origin.xml & copy.xml. As you may know, the error messege was "Invalid byte 1 of 1-byte UTF-8 sequence." .

So, what's wrong?!

Thanks in Advance.

If you specify the name of the file you are writing to, you don't want
to have an output declared in the file-serializer. You would use an
output only if you want the file serializer to write to a temporary
file, in which case you would get the URI of the temporary file in the
"data" output. In you case, the maybe the processor doesn't run at all
if you are not reading the "data" output of your pipeline.

Yes, I'd like to specify the name of the file I am writing to. as below:
copy.xpl:
        <p:processor name="oxf:url-generator"> 
                <p:input name="config"> 
                        <config> 
                                <url>file:/c:/Temp/origin.xml</url> 
                        </config> 
                </p:input> 
                <p:output name="data" id="origin-data" /> 
        </p:processor> 
       
         
        <p:processor name="oxf:file-serializer"> 
                <p:input name="config"> 
                        <config> 
                                <directory>c:/Temp</directory> 
                                <file>copy.xml</file> 
                                <make-directories>true</make-directories> 
                                <append>false</append> 
                        </config> 
                </p:input> 
                <p:input name="data" href="#origin-data"/> 
        </p:processor> 

but the result is : "The processor output must be connected"

>In you case, the maybe the processor doesn't run at all if you are not reading the "data" output of your >pipeline.

Then, is it a must to have "data" output in each pipeline?! Actually, I don't need it if I could configure file-serializer to write the file to the path I've specified.
Besides, I have just a page-flow.xml containing <page path-info="/xforms-samplecopy/"  model="copy.xpl"/>.  Did I forget something?


Thank you so much for the attention you pay :)

Good catch: this is a bug. It was introduced recently, with the
improvement to the file serializer to support temporary files. This is
now fixed, and you can find below the link to the bug for reference.
You can get this in the next nightly build. Let us know if it works
for you when you get a chance to test this.

Alex,

Here's what I've tested :

1:
origin.xml :
hi

error messege: "Root element must contain as xsi:type"
seems reasonable, but it creates an empty copy.xml too.

2.
origin.xml :
<document xsi:type="xs:string" xmlns:xs="http://www.w3.org/2001/XMLSchema" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
hi
</document>

copy.xml:
hi


3.
origin.xml:
<document xsi:type="xs:string" content-type="image/jpeg"  xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
/9j/4AAQSkZJRgABAQEBygHKAAD/2wBDAAQDAwQDAwQEBAQFBQQFBwsHBwYGBw4KCggLEA4R ...
KKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooA//2Q==
</document>

copy.xml:
/9j/4AAQSkZJRgABAQEBygHKAAD/2wBDAAQDAwQDAwQEBAQFBQQFBwsHBwYGBw4KCggLEA4R ...
KKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooAKKKKACiiigAooooA//2Q==


4.the good news :
adding <content-type>image/*</content-type> (or suprisingly other content-type in url-generator such as <content-type>application/msword</content-type>) , you can copy the .tmp file from server temporary folder to a .jpg file somewhere else. (assuming that you have uploaded a .jpg ;) )

5.
origin.xml:
<document xsi:type="xs:string" content-type="image/jpeg"  xmlns:xs="http://www.w3.org/2001/XMLSchema"

error messege: "unknown protocol: c"
and it makes an empty copy.jpg too. the difference between 5th test and the 3th one is that copy.xml has been changed to copy.jpg and whether applying <content-type> or not, the result would be the same.

Are you using the XML converter? The File serializer expects documents
in the binary or text format
(http://www.orbeon.com/ops/doc/reference-formats). So if you want to
write an XML document you need to serialize it first. Your XPL will
look something like this:

<p:processor name="oxf:url-generator">
    <p:input name="config">
        <config>
            <url>file:/Users/avernet/Desktop/gaga.xml</url>
        </config>
    </p:input>
    <p:output name="data" id="origin-data"/>
</p:processor>

<p:processor name="oxf:xml-converter">
    <p:input name="config">
        <config>
            <encoding>utf-8</encoding>
        </config>
    </p:input>
    <p:input name="data" href="#origin-data"/>
    <p:output name="data" id="converted"/>
</p:processor>

<!-- Write to another file -->
<p:processor name="oxf:file-serializer">
    <p:input name="config">
        <config>
            <directory>/Users/avernet/Desktop</directory>
            <file>copy.xml</file>
            <make-directories>true</make-directories>
            <append>false</append>
        </config>
    </p:input>
    <p:input name="data" href="#converted"/>
</p:processor>
