java - How to access as JsonNode from session | ${user.get()} -


i'm creating simple session object (jsonnode)

jsonnode me = mapper.readvalue(result, jsonnode.class);  httpsession session = request.getsession(true); session.setattribute("user", me);

the trying access this.

${user} // works print {"id":8,"name":"jones"..} ${user.id} // trows error "property 'id' not found on type org.codehaus.jackson.node.objectnode" ${user.get(0)} // nothing printed out. ${user.size()} // return 4, id,name,username,token

how re factor code fix problem, or selector?

the version @mindas suggested should work, unless using tomcat 7. seems tomcat 7 has bug when calling overloaded methods jsp el (see issue here). using tomcat 7?

the ${user.get(0)} isn't printing because method accessing value of specified element of array node. yours not array node , if use ${user.get("id")} should value id field, unless on tomcat 7 error cannot convert id of type class java.lang.string int.

you try quick , dirty test ${user.findvalue("id")} , see if @ least result, if don't mind me saying, think better if not expose raw object jsonnode jsp sort of user pojo getters , setters id, name, username , token instead. use ${user.id} in jsp , have no issue tomcat.

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!
