Tell me the classpath that you gave at the command prompt. Also list out the
jar files that you have in lib folder of Ant, so that I can suggest you what
jar file to remove from where.

RE: java.lang.LinkageError: loader constraints violated when linking org/w3c/dom/Document class
Posted by Lee Gwun Wai <gw...@pacific.net.sg>.
I have the following in my classpath:
jaxp-api.jar
dom.jar
sax.jar
xalan.jar
xercesImpl.jar
xsltc.jar
And I have these in the lib folder of Ant:
ant.jar
junit.jar
optional.jar
xercesImpl.jar
xml-apis.jar
I tried removing dom.jar from my classpath in my build.xml, since that the
Document.class is in both dom.jar (classpath) and xml-apis.jar (Ant\lib),
but I get this error:

loader constraints violated when linking org/xml/sax/EntityResolver class
So I looked in the jars, and found that EntityResolver is in both sax.jar
(classpath) and xml-apis.jar (Ant\lib), so I removed sax.jar from my
classpath, but now I get a lot of cannot resolve symbols during javac at
lines where I import stuff like
import org.xml.sax.ErrorHandler;
import org.xml.sax.ContentHandler;
This seems to be a jar packaging problem, and I'm not that willing to
re-package the jars. Is there any way around this?

Tell me the classpath that you gave at the command prompt. Also list out the
jar files that you have in lib folder of Ant, so that I can suggest you what
