Hello everybody, I need to transfer a file using a byte array. How can I do this? I mean, the MBean has a method: public boolean fileUpload(byte[] bytes, String filename); And I want to invoke this using: boolean uploaded = (Boolean)(server.invoke(client, "fileUpload", params, sign)); Where params is a {byte[]}, how do I fill sign[]? Thank you! Andrea View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4128701#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
