This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
I have an javaapplet program that will use java IO to read and write local file. I know I need to grant rights to the client from "java.policy" file in order to bypass this( java.security.AccessControlException: access denied (java.io.FilePermission c:\item.txt write)) exception. I am currently using IBM WSAD 5.1.2 to write my applet code. I put the following code inside java.policy file(s), where BookStore folder contains all of my java files, and I would like to have to access right to read and write to the client's local files.
since IBM WSAD has a few java.policy files, and I am currently using their base_v5 library, so i modified all the java.policy under "$IBMWSAD"\eclipse\jre\lib\security\java.policy", "$IBMWSAD\runtimes\base_v5\java\jre\lib\security\java.policy" and also create ".java.policy" using command "policytool".
However, what I did is vain and the applet from the "sun java console" still gives me java.security.AccessControlException: access denied (java.io.FilePermission c:\item.txt write) when I try to write some data to the file. why? what's wrong with my work? I really feel fraustured at it and I hope I can get help from you guys
Those two paths look like they have something to do with WSAD, which may not be the same JVM that is being used to run applets. (I would imagine that WSAD likes to use an IBM JVM, while your posts talks about the "Sun Java console".)
Check the Java Plugin control panel for which JVM is used for applets, and put the policy file in its repective directory.
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
