public static byte[]	readJarEntry(com.sun.midp.security.SecurityToken securityToken, java.lang.String jarFilePath, java.lang.String entryName) Returns the content of the given entry in the JAR file on the file system given by jarFilePath. param securityToken token with permission to install software param jarFilePath file pathname of the JAR file to read. May be a relative pathname. param entryName name of the entry to return. return the content of the given entry in a byte array or null if the entry was not found exception IOException if JAR is corrupt or not found exception IOException if the entry does not exist. exception SecurityException if the caller does not have permission to install software. if (securityToken == null) { MIDletStateHandler midletStateHandler = MIDletStateHandler.getMidletStateHandler(); MIDletSuite midletSuite = midletStateHandler.getMIDletSuite(); midletSuite.checkIfPermissionAllowed(Permissions.AMS); } else { securityToken.checkIfPermissionAllowed(Permissions.AMS); } if (entryName.charAt(0) == '/") { /* * Strip off the leading directory separator, or the * resource will not be found in the JAR. */ entryName = entryName.substring(1, entryName.length()); } return readJarEntry0(jarFilePath, entryName);
