Dell,
I compared these to our server startup logs and they are almost identical so no issues there.
One test I did try was to copy the default bilaunchpad.properties file into the custom folder and then make changes to it, instead of creating a new one from scratch.
Looking at the BI 4 Admin guide section 17.2 advises against making any modifications to the default file so make sure your default file is the original state with no changes.
As always restart Tomcat after any chages and wait for the server startup entry in stderr.log before testing. Also try clearing browser cache or try from a different client machine/browser to make sure its not loading the old settings.
Regds,
Ryan
