Using the files in setup.zip and the following instructions for use normally resolves the interop issues. 1) Put HTTPClient.jar in the following directory - C:\Program Files\Java\jre1.6.0/lib/ext 2) Put .Java.policy in home directory. (ex.C:\Documents and Settings\"username") 3) Select [Control Panel]- [Java], Select [General}-[Temporary Internet Files]-[Settings...]bottom De-select(uncheck the checkbox) [Keep temporary files on my computer]
