Hi Gerald,

It's not possible as you flex functions runs on Front end as Java Classes runs on Web/Application server, So if you need to make any such calls you need to call it using the remote calls in Flex.

hi Amit i am trying to open notepad from java.
i have done it in jsp with java i is working.
but when i call from flex to jsp notepad is not opened.
i used HttpService
give me some idea Amit.

Thanks&Regards,
Gerald A

Hi Gerald,

If you open a notepad using your JSP, and call that JSP from your Flex application using httpservice then eventually it shud open the notepad on server machine as JSP will run on server machine and will open the applications on server machine. To interact with the system application on client machine you need to do it in Flex only.

Though I am not able to understand your requirement properly, can you elaborate it.

i used blaze ds to call java method.
but i got the following error please give me solution friends

[MessagingError message='Destination 'CreatingRpc' either does not exist or the destination has no channels defined (and the application does not define any default channels.)']

[AMIT PANDEY]

You this error is saying that you have not define the channel in the remoting-config.xml or that channel you defined is not available in the given package. It would be gr8 if you can share your project source, That will help us to understand the problem.
