The Solution Rating System
|
||
With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.
Your Input Matters If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support. Thank you! |

This is the code where exactly I am getting this error:
public byte[] transform(InputStream htmlStream) throws TransformerException {
try {
if(htmlStream == null)
throw new IllegalArgumentException("Unable to transform: NULL html input stream specifed");
TransformerFactory tFactory = TransformerFactory.newInstance();
// ready xsl
if(xslFile == null) {
String contextPath = ResourceBundle.getBundle("presynct").getString("deploy.dir");
if (contextPath == null) {
throw new Exception("Unable to obtain presynct context path.");
}
String xslFilename = contextPath + File.separator + "xsl" + File.separator + "html2pdf.xsl";
xslFile = new File(xslFilename);
}
if(xslFile == null || !xslFile.exists())
throw new Exception("Unable to find html2pdf.xsl file");
StreamSource xslSrc = new StreamSource(xslFile);
xslSrc.setSystemId(xslFile);
Transformer transformer = tFactory.newTransformer(xslSrc);
if(basePath == null) {
basePath =
ResourceBundle.getBundle("presynct").getString("server.url")
+ "/"
+ ResourceBundle.getBundle("presynct").getString("context.root")
+ "/";
}
if(basePath != null && basePath.length() > 0)
transformer.setParameter("basePath", basePath);
// ready input
StreamSource ssrc = new StreamSource(htmlStream);
// ready output
ByteArrayOutputStream baos = new ByteArrayOutputStream();
StreamResult sresult = new StreamResult(baos);
// transform
//log.debug("Html2PdfTransformer.transform() transforming to bigfaceless-compliant XML input...");
transformer.transform(ssrc, sresult);
byte[] rval = baos.toByteArray();
baos.close();
return rval;
}
catch(TransformerException te) {
te.printStackTrace();
throw te;
}
catch(Exception e) {
throw new TransformerException("Html2PdfTransformer.transform() EXCEPTION",e);
}
}
