java - jmap dump not working -


no exception thrown still cant find dump.bin file in desktop folder, path wrong?

 public static void dumpheap()         {             system.out.println("dumping data");              string name = managementfactory.getruntimemxbean().getname();             system.out.println("name :" + name);             string pid = name.substring(0, name.indexof("@"));             system.out.println("pid :" + pid);              string[] cmd = { "jmap", "-dump:file=/users/myname/desktop/dump.bin", pid };             process p;             try {                 p = runtime.getruntime().exec(cmd);             } catch (ioexception e) {                 e.printstacktrace();             }

i had force using -f

public static void dumpheap()      {         system.out.println("dumping data");          string name = managementfactory.getruntimemxbean().getname();         system.out.println("name :" + name);         string pid = name.substring(0, name.indexof("@"));         system.out.println("pid :" + pid);          string[] cmd = { "jmap", "-dump:file=/users/myname/desktop/dump.bin", "-f", pid };         process p;         try {             p = runtime.getruntime().exec(cmd);         } catch (ioexception e) {             e.printstacktrace();         }

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!
