Hi. I'm new to JBoss and have installed version 4.2.3.GA on my WinXP Pro system to match our server. The Java servlet needs to write an uploaded file to a folder on my machine. The app's is located in this folder: C:\jboss\jboss-4.2.3.GA\server\default\deploy\premupload.war Its structure is like this: ...\premupload.war | \uploads\ | \WEB-INF\ | upload.jsp The upload folder (which is off the root of the app) is defined in the web.xml file as this: <context-param> | <param-name>UploadDirectory</param-name> | <param-value>/uploads/</param-value> | </context-param> I try to fetch the upload folder using this line in the servlet: String uploadDirectory = this.getServletContext().getInitParameter("UploadDirectory"); The app blows up with the following error referring to the above line: java.lang.NullPointerException | org.unctv.fileupload.UploadHandler.doPost(UploadHandler.java:47) | javax.servlet.http.HttpServlet.service(HttpServlet.java:710) | javax.servlet.http.HttpServlet.service(HttpServlet.java:803) | org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) How do I refer to the upload directory? Does it need to be outside of the premupload.war folder? Your guidance is much appreciated. Thanks. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4214947#...
