it was working fine with fesapi2.4

I have also build the fetpapi(master) using same fesapi 2.6 but it is giving me the error of

session.getProtocolException not found.

Our main purpose is use these api with ETP server for reading Blob (grid zvalues )

thanks in advance

Hi,

From [FESAPI2.5](https://github.com/F2I-Consulting/fesapi/releases/tag/v2.5.0.0) : “make integer arrays named as in C++11”. Integer names in C++11 are named `intX` or `uintX` where `X` is the size of the integer in bits.  
For instance a previous UIntArray should now be named UInt32Array.  
For instance a previous IntArray should now be named Int32Array.

FETPAPI is not released yet and still in developement. You might expect some methods to appear and disappear.  
Furthermore, latest FETPAPI version is now based on FESAPI 2.7 (not 2.6).  
Endly, session.getProtocolException does no more exist, Please override CoreHandlers.on\_ProtocolException if you want to catch the server exceptions.
