Read, Write and create files from java applet.
Dear All,
I have created a two files. One is applet and one application file. I am creating a instance of application file in applet. Application file is used for reading, writing and creating files. When I invoke applet from broser it dipslays error wrt file access permission. From the forum search I know that we need to sign the applet / edit the java policy to run the code locally. Final delivery of my code should execute on different system. Its not web. I have created a html page on submitting the form it invokes applet to read the form values from param and needs to update the values in xml file located locally. Please help me on how I can proceed with this fix.
Thanks in advance.

Sorry if I have not stated the problem clearly. I need to update content to files hosted in local system using java applets.
I belive there are two ways to achive that.One with jar signer and one with modifying the java policy file. But this application needs to be installed in different system locally as I have created a application with webpage as useinterface and need to update the content in local files on submission. Not sure on how to modify the java.policy files in each end user system and whats the value we need to update in java policy file. Please help me on the steps to be followed

Or ask the administrator of your users (if there is any) to install the jre
correctly using a company's java.policy where special privileges can be
given by an administrator.
