excel - Jasper iReport custom date and custom time -


in excel, have date format yyyy.mm.dd hh:mm , time format hh:mm. set source ireport database.

for date set custom date format in ireport, same in excel. set class="java.util.date".

for time, class should choose? i've tried many, none working.

i think, problem is, cannot set custom date format, ireport not recognise it.

thank help.

it quite harder solve new case old 1 described in excel datasource in jasperreports/ireport: unable value field 'date' of class 'java.sql.date' post.

solution

datasource, data

the xls file (flights.xls) contains data this:

enter image description here

the cells in departure , duration columns have text format (without patterns).

datasource, configuration

the excel datasource have configuration (in ireport, can same java code):

enter image description here

the date format set yyyy.mm.dd hh:mm reading data departure column of excel file.

it impossible declare several fields of java.util.date excel datasource contains date data different patterns.
behavior determined implementation net.sf.jasperreports.engine.data.jrxlsdatasource.getfieldvalue(jrfield) method. can see source code of class , can change behavior.

template

the fields in report be:

<field name="flight" class="java.lang.string"/> <field name="departure" class="java.util.date"/> <field name="duration" class="java.lang.string"/>

note duration field has java.lang.string type.

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!
