Hi Vinod Kumar Akurathi,

This is a very generic error and could be caused by a number of issues. The first thing I would suggest is to see if you can access the Web Services through the URL (Should be able to locate it within the Web Intelligence Rich Client). If you can access the Web Service through your browser, I don't suspect it's an issue with your Tomcat server.

If you can't access it, stop the Tomcat server, clear out the cache directory ($CATALINA_HOME\work\Catalina\localhost), and start the Tomcat server. Try to access it again. If you're still unable to, check to see if it's a network issue, as it could be that you're unable to connect to the various servers.

The next place to look is to see if multiple people are receiving the same error. It could be a network issue from the individuals desktop to the server, or it could be report related. This way, you can narrow down the issue as if it's everyone, then more than likely it might be a connection issue between the desktop & server. If it's just one or two people, chances are it's a desktop related issue.

If all else fails, see if you can use Fiddler or WireShark or some form of HTTP trace to see where the connection is being dropped. This will help you identify the issue a bit more.

Let me know if this works or not or if there is a new error. Thanks,

-Victor

Hi Vinod,

1. Once check with the host file in your system in the below mentioned path whether your server details has been entered in it.

path: C:\Windows\System32\drivers\etc\hosts.

If it is not done, then enter your "server IP address" space "server name" and finally save the file.

After doing it, reopen the dashboard and check whether you are getting the error.

2. Check whether the available "Dashboard Processing Servers" are up in the Central Management console(CMC).

Hi Sapnesh,

All the four pages is getting the same error message. And i think the web services(4) which i have created is causing the problem.

Thanks,

Vinod.

hi

even try to check the crossdomain file on server ::> from C:\Programme\Business Objects\Tomcat6\webapps\ROOT\

it should contain below code:

<?xml version="1.0"?>

<!DOCTYPE cross-domain-policy SYSTEM

"http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd ">

<cross-domain-policy>

<allow-http-request-headers-from domain="*" headers="*" secure="false" />

<allow-access-from domain="*" secure="false" />

</cross-domain-policy>

The reason you are getting that error is It is unable to contact the server. Try to restart the server.
