Hi. I have written my own datasource and SourceStream, and placed them in teh correct directories (javax/media/protocol/steveSourceStream). I have run the applet under win32 jdk1.1.8 and JMF1.1 (win32 optimised), and the applet finds the datasource class, and does the job. However, when ported to linux (jdk 1.1.7, JMF 1.1 all-platforms), the applet returns with a NoDataSourceException. I have then tried running jdk1.1.8 and JMF1.1 (all-platforms) on Windows, and that comes up with the same NoDataSourceExcption. Help! I need the linux version to stream the media!!! The samples in teh JMF work ok with all versions (playing back AU files). Thanks. Steve. ---------------------------------------------------------------------- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
