Question

I understand this question couldn’t be more beginner, but I am having a hard time to grasp why it is not working. The Apache Xerces-J comes with a binary distribution that I am sure many of us uses. Within it, there are all the library jars and sample jars dom.Writer being one of it I am trying to run:

LICENSE                         NOTICE                      resolver.jar
LICENSE-SAX.html                NOTICE.resolver.txt         samples/
LICENSE.DOM-documentation.html  NOTICE.serializer.txt       serializer.jar
LICENSE.DOM-software.html       Readme.html                 xercesImpl.jar
LICENSE.resolver.txt            data/                       xercesSamples.jar
LICENSE.serializer.txt          docs/                       xml-apis.jar

My understanding is that Java’s default class path will search current direcotry first, so if I run

java dom.Writer

in that directory, then it should work … shouldn’t it? but no, and then I tried a bunch of different ways of giving the classpath, including java6’s wildcard, nothing works.

so I know xercesSamples.jar contains dom.Writer, but I couldn’t figure out how to run it .. silly, huh? Someone please enlighten me.

The error message is like:

Exception in thread "main" java.lang.NoClassDefFoundError: dom/Writer
Caused by: java.lang.ClassNotFoundException: dom.Writer

Include xercesSamples.jar in your classpath. Jars have to explicitly specified in classpath.

java -cp xercesSamples.jar:. dom.Writer
