MATLAB / Datafeed compiled code with Bloomberg APIv3 / Java library: Java Exception -

am trying compile matlab code employs bloomberg's apiv3 via datafeed toolbox. code runs fine within matlab. compiler works fine on code without java. javaclasspath references api via:

dynamic java path  c:\blpv3\api\apiv3\javaapi\v3.7.1.1\lib\blpapi3.jar 

i several compilation errors relating java (stacktrace below) on compilation :

mcc -m -r -startmsg -r -completemsg -v my_prog.m 

i suppose need tell mcc link blpapi3.jar more explicitly, how? need set static java path?

any appreciated!

after more browsing , lots of trials, have resolved issue. answers in several posts on site already. anyway, there several issues...

1

it appears

java exception occurred: java.lang.noclassdeffounderror

is runtime error, not compile error. fix updated classpath.txt in both compiler , mcr, located at,

$matlabroot\toolbox\local\classpath.txt

to this

javaclasspath

    static java path  c:\program files\matlab\r2012a\java\patch                                                        c:\blpv3\api\apiv3\javaapi\v3.7.1.1\lib\blpapi3.jar        

alternatively, blpapi3.jar can copied

$matlabroot/java/jarext

alongside other jar files.

also, removed dynamic java path, works matlab ide.

2

i have disabled addpath in startup.m clause such as

if ~isdeployed && ~ismcc addpath d:\matlab ... end

3

arguments mcc must include directories in source files located, i.e.

mcc -m -i 'source_file_dir' -v top_level_function.m

4

when handling files within code, reference relative $matlabroot, e.g.

if isdeployed sfile_path = fullfile(matlabroot,'..','input',sfile_name); else sfile_path = which(sfile_name); end

5

notice $matlabroot of mcr different $matlabroot of matlab ide.
