Exception while executing integration tests in maven

Question

Getting following exception while executing integration tests using mvn verify against my webapp. The integration tests just loads the server url using HtmlUnit and checks for the status code 200. Not sure what I am missing here. It looks like the resource filtering is not working as expected here. Please guide.

Answer 1

Found the solution to the filtering problem with test resources.

Replaced

 <resources>
        <resource>
            <directory>src/test/resources</directory>
            <filtering>true</filtering>
        </resource>
    </resources>

with

<testResources>
    <testResource>
        <directory>src/test/resources</directory>
        <filtering>true</filtering>
    </testResource>
</testResources>
