java - UnsatisfiedLinkError: gnu.io.RXTXPort.nativeSetLowLatency() -


i trying set low latency when using rxtx library, error getting while running under ubuntu/linux is:

unsatisfiedlinkerror: gnu.io.rxtxport.nativesetlowlatency()z

it seems problem missing library seems me in place (all files (librxtxi2c.so, librxtxparallel.so, librxtxraw.so, librxtxserial.so) in jre/lib , jar in jre/lib/ext - rxtxcomm.jar)

any idea problem here?

instead of putting libraries directly jre, i'd recommend setting classpath , native library directory explicitly @ runtime. can with:

java -djava.library.path=<path-to-so-files> -classpath <your-jarfile>   mainclass

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!
