Hello Andrew T. the program must access local files, if I launch it using webstart, should i use JNLP API to accomplish this? so i also need to modify the original source code? in addition ,how can i config the "codebase="http://.." if the jnlp file is in current directory? the only way i know is like: codebase="file:///D:\...", but it's a absolute path, ^ ^"Thanks. > > > > > I receive an Exception when excute a jar that compiled from jdk > > > > > 1.5.0_08: > > > > > "do not use gui.GUI.add(), use gui.GUI.getContentPane().add instead" on > > > > > jvm 1.4.2_08 > > > > > However, i don't want to change the source code :).

A webstart application can access local files at least two ways. 1) unstrusted app. using the JLNP API FileService, but if you do not want to alter the code, the other option is to .. 2) sign it, and request either all-permissions or j2ee-client-application-premissions in the JNLP launch file. >..so i also need to modify the > original source code?

Open a command prompt pointing to the directory of the JNLP file, then type (something like).. javaws -codebase file:. file:./thejnlp.jnlp ..that should load the WebStart manager, replacing the codebase in 'thejnlp.jnlp' with the current directory. (Note the codebase in the JNLP file can be a complete lie, the launch file does not need to exist on the net, for this to work) HTH Andrew T. > > > > > > I receive an Exception when excute a jar that compiled from jdk > > > > > > 1.5.0_08: [quoted text clipped - 45 lines] > > Andrew T. Thanks a lot Andrew T I'll select Option 2). ^ ^ i hope i can accomplish this problem according to your help. But I found i realy can't distinguish the "file:", "file:." , and "file:///" :'( I write a jnlp test file below and they are all ok <jnlp codebase="file:." href="file:D:\c14\jnlp\filechooser.jnlp"> <jnlp codebase="file:" href="file:///D:\c14\jnlp\filechooser.jnlp"> <jnlp codebase="file:." href="file:\filechooser.jnlp"> <jnlp codebase="file:" href="file:\filechooser.jnlp"> Free MagazinesGet these publications absolutely FREE for up to 12 months.
