Dear javaranch members,

I have a small problem, in which i am struck for few days now.

Here is my Get Restful code, in this i use Pathparam to pass parameter via the web-browser.

As it can be seen from above code i pass the parameter using PAthParam to the python file But when i enter the parameter value (i.e) name1=USB0::0x164E::0x13EC::TW00008555; which is the id of my instrument connected and command=*IDN?, which is SCPI command to get the name of the instrumnet, in the browser window i get an error: Command result NULL, but in reality i should get either 0 or 1.

But am kinda confused if the values i am passing in the browser window is actually passed in or not?

If not what i could do to pass this values? I have attached the image of the error,
Is my code correct? or am i missing something in it?

Any help would be very much appreciated. Thanks a ton in advance.!
