POCreate a playlist in iTunes with COM and Java
text
Body
copied!<p>How do I create a playlist in iTunes from Java, using COM (on windows i.e. no AppleScript)?</p> <p>I have found a library <a href="http://dot-totally.co.uk/software/itunescon/" rel="nofollow noreferrer">here</a> that does most of what I need, and I have added some code to ITPlaylist.java, to call the "AddTrack" method (mentioned <a href="http://developer.apple.com/sdk/" rel="nofollow noreferrer">in the docs</a>) on the iTunes object ITPlaylist :</p> <pre><code> public void addTrack(ITTrack track) { ITPlaylistKind k = getKind(); if (k == ITPlaylistKindUser) { Dispatch.put(object, "AddTrack", track); } else throw new UnsupportedOperationException("can only add track to user playlists - kind : " + k); } </code></pre> <p>But I get an error :</p> <pre><code># A fatal error has been detected by the Java Runtime Environment: # # EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x1000e150, pid=3184, tid=3896 # # JRE version: 6.0_15-b03 # Java VM: Java HotSpot(TM) Client VM (14.1-b02 mixed mode, sharing windows-x86) # Problematic frame: # C [jacob-1.14.3-x86.dll+0xe150] # # An error report file with more information is saved as: # Z:\\hs_err_pid3184.log # # If you would like to submit a bug report, please visit: # http://java.sun.com/webapps/bugreport/crash.jsp # The crash happened outside the Java Virtual Machine in native code. # See problematic frame for where to report the bug. </code></pre> <p>when I try and call this method. The log file contains:</p> <pre><code># # A fatal error has been detected by the Java Runtime Environment: # # EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x1000e150, pid=3040, tid=3756 # # JRE
