drools - Reading Excel Sheet in Guvnor Rule -


i have take decision in guvnor rule based on value in excel sheet. possible in guvnor rule? let me explain simple example of want exactly:

rule: read average salary in particular country person. based on avg. salary compute other calculations in rule.

i person's country in input. have take country , check in excel sheet average salary , perform calculations based on it.

excel content:

country salary

ind $2000

usa $3000

chn $1900

now if input person country ind. how can read excel in guvnor?

is better read excel in guvnor or read in java code before calling rule , adding value 1 of pojo field.

any appreciated.

i parse xls file externally , insert data facts (or globals if wish). you can write rules like:

when     person($country: country)     avgsalary(country == $country, $salary: salary)  //this fact comes xls.     ... end

another option encapsulate parsing of xls file , provide mechanism extract particular salary particular country. in case, can provide mechanism using global , write rules one:

global xlsparser;   // parser class  rule "..." when     person($country: country)     $salary: double() xlsparser.getavgsalary($country)     ... end

hope helps,

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
