java - How I can change default timeout for web services call on Google app engine? -


my google app engine application use web service, web service pretty slow respond , application crashes :

java.net.sockettimeoutexception: timeout while fetching url: http://...

to call web service, use classes generated wsimport (java tool parse existing wsdl file , generate required files).

i need change default deadline (5 seconds) either call or globally app url fetches.

app engine docs :

you can set deadline request, amount of time service wait response. default, deadline fetch 5 seconds. maximum deadline 60 seconds http requests , 10 minutes task queue , cron job requests. when using urlconnection interface, service uses connection timeout (setconnecttimeout()) plus read timeout (setreadtimeout()) deadline.

source : https://developers.google.com/appengine/docs/java/urlfetch/#java_making_requests

i tried add lines (in strong below) in code change deadline did'nt work :

url urlconnection = new url(url);

urlconnection connection = urlconnection.openconnection();

connection.setconnecttimeout(180000); // 3 minutes

connection.setreadtimeout(180000); // 3 minutes

sws webservice = new sws(urlconnection, new qname("http://...", "sws"));

note : sws main class generated wsimport wsdl

posted here min ago, there no accepted answer: can globally set timeout of http connections?

for app engine jax-ws have set request context (tested today sdk 1.9.15). normal machines cannot go higher 60s , have switch bigger machines (bx) better use task queue.

for local testing use bindingproviderproperties.connect_timeout , bindingproviderproperties.request_timeout, not on app engine jre white list , code inspection might warn that. equivalent strings can used though:

com.sun.xml.internal.ws.connect.timeout com.sun.xml.internal.ws.connect.timeout

for deployment app engine:

com.sun.xml.ws.connect.timeout com.sun.xml.ws.request.timeout

a full example how apply auto-generated code jax-ws 2.x, values have provided in milliseconds:

@webendpoint(name = "your.randomserviceport") public yourserviceinterface getyourrandomserviceport() {     yourrandomserviceinterface port = super.getport(yourrandomservice_qname_port, yourrandomserviceinterface.class);     map<string, object> requestcontext = ((bindingprovider)port).getrequestcontext();     requestcontext.put("com.sun.xml.ws.connect.timeout", 10000);     requestcontext.put("com.sun.xml.ws.request.timeout", 10000);     return port; }

html - Sizing a high-res image (~8MB) to display entirely in a small div (circular, diameter 100px) -

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .

identifier - Is it possible for an html5 document to have two ids? -

i wondering if html5 element can have 2 ids, this: <button id="thing1" id="thing2" name="button1" onclick="change()">click here</button> or this: <button id="thing1, thing2" name="button1" onclick="change()">click here</button> also, if 1 of ids said 1 thing, , other id said thing, 1 used? tl;dr : no. in versions of html, each element can have 1 id. see the spec : the id attribute specifies element's unique identifier (id). [dom] the value must unique amongst ids in element's home subtree , must contain @ least 1 character. the value must not contain space characters. note: there no other restrictions on form id can take; in particular, ids can consist of digits, start digit, start underscore, consist of punctuation , etc. note: element's unique identifier can used variety of purposes, notably way link specific parts of document usin
