Hi,

After I have upgraded the selenium-java jar from 2.24.1 to 2.30.0, 
I am getting the following exception at run-time when my code is calling the FirefoxDriver
constructor:

driver = new FirefoxDriver(firefoxBinary, firefoxProfile);

What's your full classpath? Do you use selenium-server-standalone? Or maven? Or any
other way to build the classpath for selenium tests?

I found out that it is the apache poi-ooxml 3.9 jar that I'm using for processing xlsx
files which caused the issue.
When building using Maven, it is pulling in the xml-apis jar 1.0.b2 which is not compatible
with the new selenium version. 
My current work around is to exclude the xml-apis jars from the poi dependency.

Yes, selenium requires xml-apis-1.4.01.jar that is much newer.
Good to know you resolved the issue!

Thanks for providing this solution. I was also facing the same issue, now resolved with
including below dependencies to pom.xml:
            <dependency>
                <groupId>xml-apis</groupId>
                <artifactId>xml-apis</artifactId>
                <version>1.4.01</version>
            </dependency>

            <dependency>
                <groupId>org.apache.poi</groupId>
                <artifactId>poi-ooxml</artifactId>
                <version>3.9</version>
                <exclusions>
                    <exclusion>
                        <artifactId>xml-apis</artifactId>
                        <groupId>xml-apis</groupId>
                    </exclusion>        
                </exclusions>
            </dependency>

Seeing the same issue under maven, and looking at the dependency tree, unless I am missing
something, this seems to be a pb with the selenium-java and driver dependencies.
In the tree below notice that a) the firefox driver (which I am trying to instantiate)
doesn't declare a dependency on xml-apis and b) the selenium htmlunit driver declares
one on xml-apis version 1.3.04.

That version is on my classpath, but I still get the NoClassDefFoundError.
Adding an explicit dependency on xml-apis 1.4.01 solved the problem.

I am also encountering this issue. Though I have used the above work around and commented
out all the xml-api's in pom.xml still I am getting the above error. :(
