java.lang.NullPointerException while using Aspose.Word jdk14

emartis · March 25, 2014, 1:30am

I am using Aspose.Words.jdk14

I am coming across an error

java.lang.NullPointerException: stream

when i try to save the pdf to an output stream

I am using doc.save(stream, SaveFormat.PDF);

If i give a local path, the pdf is generated at the given path.

if (pageContext.getParameter("submit") != null)
    DataObject fileUploadData = (DataObject)pageContext.getNamedDataObject("MessageFileUpload");

ByteArrayOutputStream stream = null;
stream = new ByteArrayOutputStream();
String fileName = (String)fileUploadData.selectValue(null, "UPLOAD_FILE_NAME");
BlobDomain uploadedByteStream = (BlobDomain)fileUploadData.selectValue(null, fileName);
byte[] in = uploadedByteStream.toByteArray();
ByteArrayInputStream inStream = new ByteArrayInputStream(in);
doc.save(stream, SaveFormat.PDF);

here the code breaks and an exception is thrown

catch (Exception ex)
{
    throw new OAException(ex.toString(), OAException.ERROR);
}

My reqt is to save the pdf in the database…So it is necessary for me to store the generated pdf in the output stream

I am able to execute the same code on R12 JDeveloper tool (version 10.1.3.3.0.3).

Issue is that my client uses on Java 1.4 11i Jdeveloper (version 9.3.3.0) and i face the above error in the lower version.

If the problem still remains, please attach your input Word document here for testing? I will investigate the issue on my side and provide you more information.

Could you please execute the following code snippet at your end and share your finding with us?

Document doc = new Document(MyDir + "in.docx");

doc.save(dstStream, SaveFormat.PDF);

I have tried using the jar you have provided. I come across the three errors on compilation :

Error: cannot access class com.aspose.words.ë61; file com\aspose\words\ë61.class not foundError: cannot access class com.aspose.words.ë61; file com\aspose\words\ë61.class not found
Error: cannot access class com.aspose.words.ë5L; file com\aspose\words\ë5L.class not foundError: cannot access class com.aspose.words.ë5L; file com\aspose\words\ë5L.class not found

On using the existing jar and the code provided by you above I get :

ByteArrayOutputStream stream = null;
stream = new ByteArrayOutputStream();
Document doc1 = new Document("C:\\Elvina\\test.docx"); 
doc1.save(stream, SaveFormat.PDF);

Error as below :

com.aspose.words.FileCorruptedException: The document appears to be corrupted and cannot be loaded

Hi,

1.Using Aspose.words-jdk16-7.0.0.jar & java version 1.6.0_20 and any other MS Word (Except 2013) my requirments are fulfilled.
The error on using above is :
com.aspose.words.FileCorruptedException: The document appears to be corrupted and cannot be loaded.

If I use the one which you have provided latest version (v14.2.0)latest version (v14.2.0) then i get compilation error on a simple java application.
Error: ë61 not found in class com.aspose.words.CompositeNode in class com.aspose.words.DocumentBase in class com.aspose.words.Document
Error: ë5L not found in class com.aspose.words.Document
Error(15,13): ë4M not found in class test.Class1.

My questions :

Why does my system only support Aspose.words-jdk16-7.0.0.jar and not Aspose version (v14.2.0).
Why does Aspose.words-jdk16-7.0.0.jar not support .docx ( MS office 2013).

Hi Elvina,

Thanks for your inquiry.

emartis:

1. Why does my system only support Aspose.words-jdk16-7.0.0.jar and not Aspose version (v14.2.0).

Aspose.Words for Java is available for Java 1.4, 1.5, 1.6 and 1.7 and will run in any place where Java is installed. Please read the system requirements from here:

https://docs.aspose.com/words/java/system-requirements/

Perhaps there is some issue at your side. As you are using JDK 1.6, please use the Aspose.Words.14.2.jdk16.jar Jar in your project.

Please remove all jar files from your application and include the latest Jar file of Aspose.Words for Java 14.2.0 (Aspose.Words.14.2.jdk16.jar). Hope this helps you.

Could you please create separate simple application which only loads the document at some different system and share your finding with us? I have successfully loaded the document into Aspose.Words DOM. Please check the attached image for detail.

emartis:

2. Why does Aspose.words-jdk16-7.0.0.jar not support .docx ( MS office 2013).

You are using very old version of Aspose.Words. The old version of Aspose.Words does not fully support MS Word 2013 documents.
