Trapping an Error from a web service

[Patrick]

I'm trying to figure out the best way to trap for specific errors when
making calls to a web service. For instance, if the web service
returns an "invalid login" error, I want to be able to trap the error
and take the user to a login page. All of the errors return from my
web services come back as RemoteException objects. Is there a way to
trap for specific web service errors without parsing the error
message? Thanks.

I get this msg when I try to run an applet in IE6 under win2K SP 4:
"Java runtime envir. can't be loaded from <\bin\hotspot\jvm.dll>"

C:\>java -version
java version "1.4.2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2-b28)
Java HotSpot(TM) Client VM (build 1.4.2-b28, mixed mode)

On the plug-in ctrl panel, which is version 1.3.1_03, I first enabled the
plug-in for 1.4 then the default. Should it not show 'Help' buttons? it
does in the online docs for 1.4.2. I'm also missing ControlPanel.html in my
JDK.

I also disabled a setting in IE6 > tools > i'net > advanced > JIT compiler
for virtual machines enabled.

Hope you can help,
Peter

UPDATE:

I should have mentioned that the CLASSPATH includes:
C:\Jdk1.4.2\lib;
C:\Jdk1.4.2\jre\lib\rt.jar;
C:\Jdk1.4.2\lib\tools.jar;

I really would appreciate some help with this.

'bye,
Peter.
