Needed help on the Xalan jar..

[Vivek Routhu]

Hi Team,

Currently I am using the below 3 jars for XML reading , writing and 
transferring XSLT to HTML conversion.

  *   xalan.jar
  *   xerces.jar
  *   xercesImpl.jar


In the code I have added the below XMLConstants.

TransformerFactory tf = TransformerFactory.newInstance();
               tf.setAttribute(XMLConstants.ACCESS_EXTERNAL_DTD, "");
              tf.setAttribute(XMLConstants.ACCESS_EXTERNAL_STYLESHEET, "");

After adding I am facing below error.

              Exception in thread "main" java.lang.IllegalArgumentException: 
Not supported: http://javax.xml.XMLConstants/property/accessExternalDTD
              at 
org.apache.xalan.processor.TransformerFactoryImpl.setAttribute(TransformerFactoryImpl.java:571)

Case 1:
So I have gone through the internet and updated xerces.jar,xercesImpl.jar with 
xerces-xercesImpl-2.11.jar
Now I have these below jars in my project.


  *   xerces-xercesImpl-2.11
  *   xalan.jar

Again I have run the same code I am getting same error. If I remove the 
xalan.jar from the lib it is working fine.

Case 2:
And if I update the xalan-2.7.2.jar also I am getting same error like above.


  *   xerces-xercesImpl-2.11
  *   xalan-2.7.2

Could you please clarify on the below


  1.  Is there any relation between xerces-xercesImpl -2.11 and xalan jars?


  1.  I am using java_8.0_202 version is there anything referring in the java?


  1.  can I remove the xalan jar from the whole project?

Any help will be much appreciated. Thanks  in advance.

Please let me know if you need any further inputs.

Thanks & Regards,
Vivek.
