sorry but what does xpathAPI is? plz tell me so that i can add it — Divya, May 01 '14 at 10:44
@mark o'connor this is not duplicate(i already added xalan-2.7.1.jar but issue not resolved) — Divya, May 02 '14 at 05:17
Clearly it's not in the classpath. Xalan contains this class, see: http://search.maven.org/#search|ga|1|fc%3A%22org.apache.xpath.XPathAPI%22%20AND%20v%3A%222.7.1%22 — Mark O'Connor, May 02 '14 at 10:13

The missing class is contained in xalan-2.7.0 (See Maven central). So I think the problem is how your classpath has been set.

Considering that this appears to be an error reported by the xmltask task, does this mean the error is being thrown by ANT?

Google found the following example which might be the answer to your problems:

https://wiki.nci.nih.gov/display/NBIA/Migration+to+Java+7

Add the xalan jar to the classpath of your taskdef:

<taskdef name="xmltask" classname="com.oopsconsultancy.xmltask.ant.XmlTask">
  <classpath>
    <pathelement path="${common.lib.dir}/xmltask-1.15.1.jar" />
    <pathelement path="${common.lib.dir}/xalan-2.7.1.jar"/>
  </classpath>
</taskdef>

I already have these entries in classpath, wondering what is wrong here — Divya, May 02 '14 at 05:16

if using maven add this to your dependencies section:

<dependency>
    <groupId>xalan</groupId>
    <artifactId>xalan</artifactId>
    <version>2.7.0</version>
</dependency>

It already have xalan-2.7.0.jar – Divya May 01 '14 at 10:44
i think version matters – Akash kumar May 01 '14 at 10:50
I agree but here I don't think so(with all due respect) – Divya May 01 '14 at 20:32

Add xpath to your classpath and try the deploy again. If you are not sure which xpath jar you need search in the tomcat libraries folder for xpathapi jar

Xpathapi is a jar used for evaluating xpaths (related to xml) in java. if you are not sure which version you need, google for it and fetch the latest xpath api jar .

In Build.xml, change the java version to 1.7 and classpath XMLTask from 1.15.1 to 1.16.1.. It works

This is how I solved this, inlcuding Xalan and Serializer

Download xalan-j2-2.7.0.jar & serializer-2.7.0.jar

Update build.xml to include these jars in path

<taskdef name="xmltask" classname="com.oopsconsultancy.xmltask.ant.XmlTask">
    <classpath>
        <pathelement location="../xmltask-v1.14.jar"/>
        <pathelement path="../xalan-j2-2.7.0.jar"/>
        <pathelement path="../serializer-2.7.0.jar"/>
    </classpath>
</taskdef>

This should get it running.

You should remove import org.apache.xpath.operations.String;.
