I stripped down my dependencies to just only a few, and if I omit the

I use the simple Ant script, no Eclipse, no Maven in this setup. And within 
my Ant script, I print the current classpath, which results in:

I recently upgraded to GWT 2.8.2 (from the old version 2.6.0) I ran into 
the same problem 
("org.apache.xerces.parsers.XIncludeAwareParserConfiguration cannot be cast 
to org.apache.xerces.xni.parser.XMLParserConfiguration").

What I would like to understand is, is the Xerces version packaged with GWT 
2.8.2 (gwt-dev.jar) incompatible? The fix with 

-Djavax.xml.parsers.DocumentBuilderFactory=com.sun.org.apache.xerces.
internal.jaxp.DocumentBuilderFactoryImpl
-Djavax.xml.parsers.SAXParserFactory=com.sun.org.apache.xerces.internal.jaxp
.SAXParserFactoryImpl

seems to work.

So are we talking about a kind of dependency-problem with GWT (2.8.0+)?

I found the solution for my problem with this exception, according to 
Javadoc and databasesandlife.com 

 I 
have used two system properties and problem was gone, because our code was 
written to use JDK xerces

-Djavax.xml.parsers.DocumentBuilderFactory=com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl
-Djavax.xml.parsers.SAXParserFactory=com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl

Re: GWT2.8 : org.apache.xerces.parsers.XIncludeAwareParserConfiguration cannot be cast to org.apache.xerces.xni.parser.XMLParserConfiguration

2016-12-15 Thread Adam Gerbert 
Ran into the same issue after upgrading to 2.8 from 2.7. Only happened in 
super dev mode, as the xerces dependency was coming from gwt-dev.jar. I 
fixed it in the same manner as Ian Whyman (thanks!), by including the 
dependency explicitly.

Re: GWT2.8 : org.apache.xerces.parsers.XIncludeAwareParserConfiguration cannot be cast to org.apache.xerces.xni.parser.XMLParserConfiguration

2016-12-05 Thread Peter Petranik 
Thx guys for quick response, but my problem was only in some Eclipse 
related file. I am using Eclipse SDK 4.6.1 with GWT Eclipse Plugin 
. After I have switched 
from GWT 2.7 to GWT 2.8 I missed in $PROJECT_DIR/.settings / 
com.gwtplugins.gwt.eclipse.core.prefs the additional line 

*filesCopiedToWebInfLib=gwt-servlet.jar* 

.. this should be added by GWT Eclipse Plugin, I have just removed it by 
mistake. With this line everything works without any problem in EclipseIDE. 
For production build, we use mojo gwt-maven-plugin and there we also do not 
have a problem.

Re: GWT2.8 : org.apache.xerces.parsers.XIncludeAwareParserConfiguration cannot be cast to org.apache.xerces.xni.parser.XMLParserConfiguration

2016-12-02 Thread Peter Petranik 
Hi, I have a same problem after I updated my application from GWT 2.7 to 2.8

That is the code that raises the exception:
DocumentBuilderFactory.newInstance().newDocumentBuilder()

And that is the exception: 
java.lang.ClassCastException: 
org.apache.xerces.parsers.XIncludeAwareParserConfiguration cannot be cast 
to org.apache.xerces.xni.parser.XMLParserConfiguration
at org.apache.xerces.parsers.DOMParser.(Unknown Source)
at org.apache.xerces.parsers.DOMParser.(Unknown Source)
at org.apache.xerces.jaxp.DocumentBuilderImpl.(Unknown Source)
at 
org.apache.xerces.jaxp.DocumentBuilderFactoryImpl.newDocumentBuilder(Unknown 
Source)
...

Has somebody already found some solution how to fix that ?

Hi Ian,

Yes, we are still seeing the problem. I've put it aside for the moment, 
hoping to revisit once we upgrade to a new GWT Release Candidate.
Glad to know I'm not the only one suffering from this :)

GWT2.8 : org.apache.xerces.parsers.XIncludeAwareParserConfiguration cannot be cast to org.apache.xerces.xni.parser.XMLParserConfiguration

2016-10-06 Thread Darren Smith 
Hi,

I am developing a  that contains within it
  - a vanilla HttpServlet
  - a GWT RPC Service implementation (RemoteServiceServlet) 

I am currently using [GWT2.8rc1].

Both servlets manipulate XML documents, and hence make calls to the 
following code
DocumentBuilderFactory docfactory = DocumentBuilderFactory.newInstance();
docfactory.setNamespaceAware(true); 

DocumentBuilder builder = docfactory.newDocumentBuilder();   // * problem 
here *

When I launch the application in Eclipse, using the embedded 
Jetty container, the vanilla HttpServlet will fail at the line
DocumentBuilder builder = docfactory.newDocumentBuilder();   // * problem 
here *

The error message is 
  java.lang.ClassCastException: 
org.apache.xerces.parsers.XIncludeAwareParserConfiguration cannot be cast 
to org.apache.xerces.xni.parser.XMLParserConfiguration

Having done some research, this exception is typically raised when there 
are several Xerces implementations found on the classpath.
(I can only see Xerces implementations in gwt-dev and in Eclipse as a 
plugin).


For the GWT RPC Service implementation, launched as part of the same 
, the XML document processing works fine - i.e. no exception 
raised.

If I comment out in the web.xml file the GWT-RPC servlet defintion, then 
the vanilla HttpServlet will perform the XML document processing without an 
exception.


Has anyone encountered similar problems?

Darren Smith.
