Hi,
1) I have a problem with an applet but couldnt find the solution
I have an applet which reads data written by LabVIEW(Instrument
software) at
particular port and have a java program to read that data and display as
chart
now the problem is, the applet is displaying the chart(written in java)
by reading the data when I am using appletviewer at DOS prompt, but if I
use browsers IE or netscape it is givng problems.
IE says class not found(though the class is there)
Netscape gives (com/ms/security/SecurityExceptionEx)
could you please suggest me what I should do to overcome this problems.
I am reading the data using DataInputStream.

2) In the same applet I am trying to write the data which I am getting
from LabVIEW into a file
but I get an exception which I cant handle
it says
java.security.AccessControlException: access
denied(java.io.FilePermission filename.tmp write)
could you suggest how to overcome this exception

I appreciate you help
thankz
Rashie
