Class ClassLoaderUtil

java.lang.Object
org.apache.commons.jxpath.util.ClassLoaderUtil
public final class ClassLoaderUtil extends Object
Port of class loading methods from org.apache.commons.lang3.ClassUtils from the Apache Commons Lang Component. Some adjustments made to remove dependency on org.apache.commons.lang3.StringUtils. Also modified to fall back on the current class loader when an attempt to load a class with the context class loader results in a java.lang.ClassNotFoundException. See org.apache.commons.lang3.ClassUtils
Since:
1.4.0
