[DTM] Exception during XLST transformation

[Mougenot Sylvain]

CONTEXT

    JDK 1.4.1

    Orion 1.5.4

    Maverick (root framework of the web-app)

    Xalan 2.4.1

    Xerces 2.2.0

 

TROUBLE

    When my XML input is relatively large (about 30Ko), sometimes,

    I've an exception (DTMException) fired by Xalan (sea end of the message ford etails).

    

    We used  some Templates to cache XSLT processing (there is the code below).

QUESTIONS
    Is there some limitation in the amount of datas allowed as xml input ?
    Do someone encounter this trouble ? (and, in this case, have you solved it?)
    Have I done something wrong ?

Where the go method is
---------------------------------------------------------------------------------------

public void go(Source input) throws IOException, ServletException{

Transformer trans;
try{
    trans = this.getCompiled().newTransformer(); [getCompiled() fired the loadTemplate method below]
}catch (TransformerConfigurationException ex){
    throw new ServletException(ex);
}

// Populate any params which might have been set
if (this.getTransformCtx().getParams() != null)
    populateParams(trans,< B>this.getTransformCtx().getParams());
Result res;
...
    res = new StreamResult(this.getNext().getResponse().getOutputStream());
...

try{
    trans.transform(input,r es);
}catch (TransformerExceptione x){
    throw new ServletException(ex);
}
...
}

---------------------------------------------------------------------------------------

(path is the xsl file path)
protected Templates loadTemplate(String path, ServletContext servletCtx) throws ConfigException{

TransformerFactory tFactory = TransformerFactory.newInstance();

if (this.uriResolver != null)
    tFactory.setURIResolver(this.uriResolver);

java.net.URL resURL = servletCtx.getResource(path);

if (resURL == null){
    log.fatal("Resource not found: " + path);
    throw new ConfigException("Resource not found: " + path);
}

log.debug("Template url is: " + resURL.toString());

return tFactory.newTemplates(new StreamSource(resURL.openStream(), resURL.toString()));
}
