<?xml version="1.0" encoding="utf-8"?>  <mule xmlns="http://www.mulesoft.org/schema/mule/core" xmlns:file="http://www.mulesoft.org/schema/mule/file" xmlns:jdbc-ee="http://www.mulesoft.org/schema/mule/ee/jdbc" xmlns:doc="http://www.mulesoft.org/schema/mule/documentation" xmlns:spring="http://www.springframework.org/schema/beans" xmlns:core="http://www.mulesoft.org/schema/mule/core" version="ee-3.4.0" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xsi:schemalocation="http://www.mulesoft.org/schema/mule/file http://www.mulesoft.org/schema/mule/file/current/mule-file.xsd http://www.mulesoft.org/schema/mule/ee/jdbc http://www.mulesoft.org/schema/mule/ee/jdbc/current/mule-jdbc-ee.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-current.xsd http://www.mulesoft.org/schema/mule/core http://www.mulesoft.org/schema/mule/core/current/mule.xsd">     <jdbc-ee:mssql-data-source name="ms_sql_data_source" user="username" password="passcode" url="jdbc:sqlserver://domain\sqlexpress:65183;databasename=muletest" transactionisolation="unspecified" doc:name="ms sql data source"/>     <jdbc-ee:connector name="database" datasource-ref="ms_sql_data_source" validateconnections="true" querytimeout="-1" pollingfrequency="0" doc:name="database">         <jdbc-ee:query key="insertrecord" value="insert databaseupdate(buyerordernumber, orderissuedate) values (#[xpath('//buyerordernumber').text], #[xpath('//orderissuedate').text])"/>     </jdbc-ee:connector>     <flow name="write_xml_file_to_databaseflow1" doc:name="write_xml_file_to_databaseflow1">         <file:inbound-endpoint path="c:\mule" responsetimeout="10000" doc:name="file"/>         <byte-array-to-string-transformer doc:name="byte array string"/>         <splitter evaluator="xpath" expression="/order/orderheader/ordernumber|/order/orderheader" doc:name="splitter"/>         <jdbc-ee:outbound-endpoint exchange-pattern="one-way" querykey="insertrecord" querytimeout="-1" connector-ref="database" doc:name="destination"/>     </flow> </mule>

i nullpointerexception. confusion lies in xpath queries, how hardcode multiple expression paths, , associate xpath query using insert? thanks.

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!
