You shouldn't have to "convert" the value unless you are generating it in
the first place, which I don't think you are doing.
I just went through this exercise, and (in our case, at least) __VIEWSTATE
is only necessary when posting a secondary form after you are already logged
in, not in the original login form. And when posting a secondary form, you
must use the __VIEWSTATE that is already encoded in the form source. You
should not be generating a new one.
Check out http://wiki.apache.org/jakarta-httpclient/ForAbsoluteBeginners for
instructions on how to post a form with HttpClient. I think IIS always
redirects after a login, so read
http://jakarta.apache.org/commons/httpclient/redirects.html as well.

Subject: Re: PostMethod - parameter in BASE64String

import org.apache.commons.codec.binary.Base64;
byte[] bytes = "I love my byte array".getBytes();
byte[] base64Bytes = Base64.encodeBase64( bytes );
System.out.println( new String( base64Bytes ) );
Outputs:

Good luck! Like Roland said, "commons-codec.jar" is already on your
classpath. The Base64 class is available for you to use.

Hello Marcelo,
it is not the same encoding used in URLs.
HttpClient does not have a Base64 encoder,
but it uses commons-codec for this purpose.
hope that helps,
