Re:
I take a look at one of my actual WAR project (converted via maven)
and the .classpath is somewhat different :
<?xml version="1.0" encoding="UTF-8"?>
<classpath>
<classpathentry kind="src" output="target/classes"
path="src/main/java"/>
<classpathentry kind="src" output="target/test-classes"
path="src/test/java"/>
<classpathentry excluding="**" kind="src" output="target/classes"
path="src/main/resources"/>
<classpathentry excluding="**" kind="src"
output="target/test-classes" path="src/test/resources"/>
<classpathentry kind="con"
path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/J2SE-1.5"/>
<classpathentry kind="con"
path="org.maven.ide.eclipse.MAVEN2_CLASSPATH_CONTAINER">
<attributes>
<attribute name="org.eclipse.jst.component.dependency"
value="/WEB-INF/lib"/>
</attributes>
</classpathentry>
<classpathentry kind="output" path="target/classes"/>
</classpath>
Could it be the problem, what's the correct .classpath/.project contents ?
