req help regarding HttpClient

Hi,

I am using HttpClient application in one of the applets.

I am using this for uploading a file.

I have a signed applet, the applet is trusted by my browser. 

The applet is able to access the file system in the host where the
applet is deployed.

But I am getting a Access Denied exception. 

Somewhere the applet is trying to read the log table of apache.

If Possible please help me in this regard.

I am pasting the stack trace here.

 

Java Plug-in 1.5.0_02

Using JRE version 1.5.0_02 Java HotSpot(TM) Client VM

User home directory = C:\Documents and Settings\Aparajith_Vangal

Aparajith,

Since this is a problem in Commons Logging, please ask on their mailing 
lists. I guess the solution is to setup commons logging 
programmatically, instead of relying on System properties, BEFORE making 
any calls to HttpClient.

Cheers

Ortwin

You have to sign all JARs, including commons-logging.
