Usage

From source file:org.ebayopensource.turmeric.eclipse.utils.io.IOUtil.java

/**
 * In the normal jar URLs usage in Windows Java puts a lock on it. And the
 * SOA Tool Handler will create a non locking URL by setting the caching
 * off. There is obviously a performance compromise made here by disabling
 * the cache.// w  w w.  j av  a 2 s. co m
 *
 * @param jarFileUrl the jar file url
 * @param jarEntryPath the jar entry path
 * @return the non locking url
 * @throws IOException Signals that an I/O exception has occurred.
