Reading text from Docx File using Docx4j

Hi I am trying to read data from one Docx file using Docx4j, so I can insert it into another file. My code is as follows:

public void getTextFromOtherFile() throws Docx4JException, JAXBException {
    File doc = new File("D:\\helloWorld.docx");
    WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage.load(doc);
    MainDocumentPart mainDocumentPart = wordMLPackage.getMainDocumentPart();
    System.out.println(mainDocumentPart.getXML());
}

The code works fine. But as soon as I insert following line in the end of above stated method, the method started generating exception:

List<Object> jAXBNodesViaXPath = mainDocumentPart.getJAXBNodesViaXPath("//w:t", true);

The exception which I am facing is as follows:

SEVERE: Servlet.service() for servlet [jsp] in context with path [/osses] threw exception [javax.servlet.ServletException: java.lang.NoSuchMethodError: org.apache.xml.utils.DefaultErrorHandler.<init>(Z)V] with root cause

My word file contains two lines which are as follows: Hello My name is abcd. I love my work. I am stuck at this point from previous 7 days but unable to resolve this problem. I also included different jar files (Xalan, xml-apis-1.3.04, serializer-2.7.2) but no luck. I am using docx4j-6.0.1.jar for my work. Can anybody please guide me for this problem. Thanks in advance.

Solution

Works for me (docx4j 6.0.1, Xalan 2.7.2, serializer 2.7.2)

I guess your classpath doesn't contain the jars you think it does.

org.apache.xml.utils.DefaultErrorHandler is in Xalan 2.7.2.

Also, the line numbers in your stack trace:

    java.lang.NoSuchMethodError: org.apache.xml.utils.DefaultErrorHandler.(Z)V 
at org.docx4j.org.apache.xalan.transformer.TransformerIdentityImpl.(TransformerIdentityImpl.java:1459) 
at org.docx4j.org.apache.xalan.transformer.TransformerIdentityImpl.(TransformerIdentityImpl.java:96)

don't match the docx4j source code, so that's strange.
