jetty - Facing java.lang.NoSuchMethodError: HttpServletRequest.getParts()Ljava/util/Collection -


i've seen many issues related exception here in , of them being solved adding "commons-file-upload" jar apache. tried use solution , i've added same version of jar projects, not seem fix problem, i'm still facing problem. know question has been asked, wonder if give me hand specific problem. stacktrace:

java.lang.nosuchmethoderror: javax.servlet.http.httpservletrequest.getparts()ljava/util/collection;     @ fr.synomia.v4.ws.remotelayer.ws.rest.restserver.getparameters(restserver.java:378)     @ fr.synomia.v4.ws.remotelayer.ws.rest.restserver.parseurlrequest(restserver.java:367)     @ fr.synomia.v4.ws.remotelayer.ws.rest.restserver.access$0(restserver.java:354)     @ fr.synomia.v4.ws.remotelayer.ws.rest.restserver$1.handle(restserver.java:67)     @ org.eclipse.jetty.server.handler.handlerwrapper.handle(handlerwrapper.java:110)     @ org.eclipse.jetty.server.server.handle(server.java:346)     @ org.eclipse.jetty.server.httpconnection.handlerequest(httpconnection.java:442)     @ org.eclipse.jetty.server.httpconnection$requesthandler.headercomplete(httpconnection.java:924)     @ org.eclipse.jetty.http.httpparser.parsenext(httpparser.java:582)     @ org.eclipse.jetty.http.httpparser.parseavailable(httpparser.java:218)     @ org.eclipse.jetty.server.asynchttpconnection.handle(asynchttpconnection.java:51)     @ org.eclipse.jetty.io.nio.selectchannelendpoint.handle(selectchannelendpoint.java:586)     @ org.eclipse.jetty.io.nio.selectchannelendpoint$1.run(selectchannelendpoint.java:44)     @ org.eclipse.jetty.util.thread.queuedthreadpool.runjob(queuedthreadpool.java:598)     @ org.eclipse.jetty.util.thread.queuedthreadpool$3.run(queuedthreadpool.java:533)     @ java.lang.thread.run(thread.java:662)

the exception thrown when invoke method getparts class restserver using httpservletrequest, i've been looking information , says version of jar used must same projects , did way, not working.

the piece of code invoking getparts() :

private map<string,object> getparameters(httpservletrequest request,boolean jsonp, string callback) {         map<string,object> lsparameteres = new hashmap<string, object>();                    collection<part> parts = null;             try {                 parts = request.getparts();//the exception begins here!

i grateful if me, time. best regards.

javax.servlet.http.httpservletrequest.getparts() available starting servlet api 3.0

things check:

  • be sure running jetty 9 (or newer)
  • make sure have web-inf/web.xml configured use servlet api 3.0 (or newer)
  • make sure build tool using servlet-api 3.1 (or newer) jars.
  • (optionally) make sure have same servlet api 3.1 jar in web-inf/lib directory.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
