I am trying to Convert XML to PDF using groovy through inputstream and aspose.jar following below:
below is my code:
def document = new Document("...dir/template.docx");
PdfSaveOptions saveOptions = new PdfSaveOptions();
ByteArrayOutputStream out = new ByteArrayOutputStream();
document.Save(out, saveOptions);
getting below error:
No signature of method: com.aspose.words.Document.Save() is applicable for argument types: (java.io.ByteArrayOutputStream, com.aspose.words.PdfSaveOptions) values: [, com.aspose.words.PdfSaveOptions@6194ebd6]
Any help would be really helpful and appreciated.
Thanks,
@Smita_Ahuja,
looks like your post is about Aspose.Words.
I’ll move your post to the appropriate category.
@Smita_Ahuja,
Could you please attach your problematic input document here for testing? We will check the issue and provide you more information.
Sure, please find attached templatetemplate.docx (11.8 KB)
Basically I am trying to convert below .Net code to java(groovy):
XmlDocument xmlDoc = JsonConvert.DeserializeXmlNode(applicationJson, XmlRootElementName);
XmlNodeReader xmlReader = new XmlNodeReader(xmlDoc);
DataSet ds = new DataSet();
ds.ReadXml(xmlReader, XmlReadMode.Auto);
string template = new Uri(Path.Combine(Path.GetDirectoryName(typeof(PdfDocumentGenerator).Assembly.CodeBase), TemplatesFolder, templateName)).AbsolutePath;
_logger.LogInformation(string.Format(@"Path to load RoT template : {0}", template));
if (!File.Exists(template))
{
throw new Exception(string.Format(@"Template {0} does not exist.", templateName));
}
var document = new Aspose.Words.Document(template);
document.MailMerge.CleanupOptions = MailMergeCleanupOptions.RemoveEmptyParagraphs
| MailMergeCleanupOptions.RemoveContainingFields
| MailMergeCleanupOptions.RemoveUnusedRegions
| MailMergeCleanupOptions.RemoveUnusedFields;
document.MailMerge.ExecuteWithRegions(ds);
PdfSaveOptions saveOptions = new PdfSaveOptions
{
Compliance = PdfCompliance.PdfA1a
};
using (Stream stream = new MemoryStream())
{
document.Save(stream, saveOptions);
int size = (int)stream.Length;
byte[] resultData = new byte[size];
stream.Seek(0, SeekOrigin.Begin);
stream.Read(resultData, 0, size);
return Convert.ToBase64String(resultData);
}
Something like:
for (int i = 0; i < dataContext.getDataCount(); i++)
{
InputStream is = dataContext.getStream(i);
Properties props = dataContext.getProperties(i);
SAXParser saxParser = factory.newSAXParser();
XMLReader xmlReader = saxParser.getXMLReader();
InputSource source = new InputSource(is);
xmlReader.parse(source);
DataSet customersDs = new DataSet();
customersDs.ReadXml(xmlReader);
}
But getting:
No signature of method: com.aspose.words.net.System.Data.DataSet.ReadXml() is applicable for argument types: (com.sun.org.apache.xerces.internal.jaxp.SAXParserImpl$JAXPSAXParser) values: [com.sun.org.apache.xerces.internal.jaxp.SAXParserImpl$JAXPSAXParser@10331559]
Sample xml is:
<?xml version="1.0" encoding="utf-8"?>
<customers>
<customer Name="John Ben Jan" ID="1" Domain="History" City="Boston"/>
<customer Name="Lisa Lane" ID="2" Domain="Chemistry" City="LA"/>
<customer Name="Dagomir Zits" ID="3" Domain="Heraldry" City="Milwaukee"/>
<customer Name="Sara Careira Santy" ID="4" Domain="IT" City="Miami"/>
</customers>
I also tried with DOM DocumentBuilderFactory also, below is my code:
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
for (int i = 0; i < dataContext.getDataCount(); i++)
{
InputStream is = dataContext.getStream(i);
Properties props = dataContext.getProperties(i);
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(is);
DOMSource domSource = new DOMSource(doc);
StringWriter writer = new StringWriter();
StreamResult result = new StreamResult(writer);
TransformerFactory tf = TransformerFactory.newInstance();
Transformer transformer = tf.newTransformer();
transformer.transform(domSource, result);
logger.info("XML IN String format is: \n" + writer.toString());
DataSet ds = new DataSet();
ds.ReadXml(writer.toString());
dataContext.storeStream(is, props);
}
but getting below error:
signature of method: com.aspose.words.net.System.Data.DataSet.ReadXml() is applicable for argument types: (java.lang.String) values: [
<?xml version="1.0" encoding="utf-8" standalone="no"?>
<customers>

<customer Name="Dagomir Zits" ID="3" Domain="Heraldry" City="Milwaukee"/>
<customer Name="Sara Careira Santy" ID="4" Domain="IT" City="Miami"/>
</customers>
@Smita_Ahuja You can simply read XML from stream into DataSet. Please see the following code:
// You can use other type of input stream.
InputStream xmlIs = new FileInputStream("C:\\Temp\\in.xml");
// Read data set from stream
DataSet ds = new DataSet();
ds.readXml(xmlIs);
DataSet.readXml method accepts as parameter either path to XML file or input stream with XML data.
Hi @alexey.noskov Thanks for your reply, I am trying from Dell Boomi grovy script
If I pass inputstream , I am getting:
for (int i = 0; i < dataContext.getDataCount(); i++)
{
InputStream is = dataContext.getStream(i);
Properties props = dataContext.getProperties(i);
DataSet ds = new DataSet();
ds.ReadXml(is);
}
Caused by: com.boomi.process.ProcessException: No signature of method: com.aspose.words.net.System.Data.DataSet.ReadXml() is applicable for argument types: (com.boomi.util.io.FastByteArrayInputStream) values: [com.boomi.util.io.FastByteArrayInputStream@9ebe7ac]
@Smita_Ahuja Could you please try with java.io.ByteArrayInputStream:
java.io.ByteArrayInputStream byteStream = new java.io.ByteArrayInputStream(bytes);
DataSet ds = new DataSet();
ds.readXml(byteStream);
Now getting:
Caused by: com.boomi.process.ProcessException: No signature of method: com.aspose.words.net.System.Data.DataSet.ReadXml() is applicable for argument types: (java.io.ByteArrayInputStream) values: [java.io.ByteArrayInputStream@28a1d103]
Possible solutions: readXml(com.aspose.words.internal.zzYzy), readXml(com.aspose.words.internal.zzZoc), readXml(java.io.InputStream), readXml(java.lang.String), readXml(java.io.InputStream, com.aspose.words.net.System.Data.XmlReadMode), readXml(java.lang.String, com.aspose.words.net.System.Data.XmlReadMode) (in groovy2 script)

Below is my code:
for (int i = 0; i < dataContext.getDataCount(); i++)
{
InputStream is = dataContext.getStream(i);
Properties props = dataContext.getProperties(i);
byte[] buff = new byte[8000];
int bytesRead = 0;
ByteArrayOutputStream bao = new ByteArrayOutputStream();
while ((bytesRead = is.read(buff)) != -1)
{
bao.write(buff, 0, bytesRead);
}
byte[] data = bao.toByteArray();
ByteArrayInputStream bin = new ByteArrayInputStream(data);
DataSet ds = new DataSet();
ds.ReadXml(bin);
dataContext.storeStream(is, props);
}
@Smita_Ahuja It is odd, because even in the suggested solution there is readXml(java.io.InputStream) overload. Have you tried to explicitly cast the stream to java.io.InputStream?
ds.ReadXml((java.io.InputStream)bin);
with:
ds.ReadXml((java.io.InputStream)bin);
still same error:

@Smita_Ahuja,
actually looks like a simple typo. In Java (Groovy), use
document.save(out, saveOptions)
instead of
document.Save(out, saveOptions)
So the first code snippet you sent will look like this:
def document = new Document("...dir/template.docx");
PdfSaveOptions saveOptions = new PdfSaveOptions();
ByteArrayOutputStream out = new ByteArrayOutputStream();
document.save(out, saveOptions);
Similar to Data.DataSet.readXml() etc. You can read more about the Aspose.Words for Java syntax in the Developer Guide.
