java - JNLP + proxy + downloading file via stream problem -

-

i'm writing application downloading csv file web , inserting data table in database. problem need setup proxy via system.setproperty("http.proxyhost", "http-proxy.domain.com"); , on. application works fine when i'm running on local system, problem when launch jnlp. @ first have had problems signing jars (i've managed it, somehow) , i'm facing problem, application running, not connect web - throws exception message "connection timeout: connect".

jnlp file looks this:

<?xml version="1.0" encoding="utf-8" standalone="no"?> <jnlp href="launch.jnlp" spec="1.0+">     <information>         <title>testimporter</title>         <vendor>hol</vendor>         <homepage href=""/>         <description>testimporter</description>         <description kind="short">testimporter</description>         </information>     <update check="always"/>     <security>         <all-permissions/>     </security>     <resources>         <j2se version="1.6+"/>         <jar href="testimporter.jar" main="true"/>             <jar href="lib/ojdbc14.jar"/>         <jar href="lib/mail.jar"/>     </resources>     <application-desc main-class="cz.test.importer">     </application-desc> </jnlp>

i'm connecting file code:

urlconnection yc = cnb.openconnection(); bufferedreader in = new bufferedreader(                     new inputstreamreader(                     yc.getinputstream()));

thanks in advance help!

you can try wrap code in doprivileged block. check 1 out:

if after implementing it, code still fails, maybe make sense paste logs java console.

-
i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines.
