ERROR in server

[Pedro Barco Bernal <pb...@ceh.junta-andalucia.es>]

Hi all!

    My question is very simple, i want to create a pdf file from a xml file
and a xsl file.
    My code is placed in a JSP and i do not know why it doesn´t run fine.
    The error i get is: "org.apache.fop.apps.FOPException: Bad file
descriptor" but i´m sure that the xml and xsl are well-formed...
    Please, if you know the solution to my problem, answer my question.
    Thanks.

This is my code:
    /*
     * xmlparam,xslparam,pdfparam are the routes of the files placed in my
server-->/u01/oracle/..../xml.xml, xsl.xsl,
    */
    File xmlf = new File(xmlparam);
    File xslf = new File(xslparam);
    File writefile = new File(pdfparam);
    writefile.createNewFile();
    Driver driver = new Driver();
    driver.setRenderer(Driver.RENDER_PDF);
    InputHandler inputHandler = new XSLTInputHandler(xmlf, xslf);
    XMLReader parser = inputHandler.getParser();
    InputSource inputSource = inputHandler.getInputSource();
    driver.setOutputStream(new FileOutputStream(writefile));
    driver.render(parser, inputSource);

This is my xml (named xml.xml)

<timesheet>
<employee>
<first_name>John</first_name>
<last_name>Doe</last_name>
<dept>5130</dept>
<location>B27</location>
<ext>2819</ext>
<type>XPT</type>
</employee>
</timesheet>

This is my xsl (named xsl.xsl)
