java - Problem with result handler -

-

i trying run java client through php sends xml server. typically takes 10 - 30 seconds receive response. when run php can tell there no load time thinking rest of code executes before response received. attempting have return response displayed in browser , written xml in same directory. none of happens. new xml created, empty.

$output = shell_exec("java soapclient4xg http://turbolink.turbo-marketing.net:8180    getlist.xml"); sleep(30); echo $output;  $filename = "getlistresult"; $filename .= ".xml"; $fp = fopen($filename, 'w'); fwrite($fp, $output); fclose($fp);

i added sleep(30) give java chance finish before passing value $output doesn't help. command java soapclient4xg http://turbolink.turbo-marketing.net:8180 getlist.xml" works. have used in soap ui , through putty running in directory. output receive this, in xml / soap format:

<?xml version="1.0" encoding="utf-8" ?> <env:envelope xmlns:xsd="http://www.w3.org/2001/xmlschema" xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance">   <env:body> <n1:getlistsresponse xmlns:n1="urn:turbolink"     env:encodingstyle="http://schemas.xmlsoap.org/soap/encoding/">   <getlistsresult xsi:type="n1:getlistsresult">     <responsemessages n2:arraytype="n1:responsemessage[1]"         xmlns:n2="http://schemas.xmlsoap.org/soap/encoding/"         xsi:type="n2:array">       <responsemessage>         <code xsi:type="xsd:string">0</code>         <message xsi:type="xsd:string">no error</message>       </responsemessage>     </responsemessages>     <datalists xmlns:n3="http://schemas.xmlsoap.org/soap/encoding/"         xsi:type="n3:array"         n3:arraytype="n1:datalist[5]">       <datalist>         <listid xsi:type="xsd:string">cvplus  </listid>         <listdescription xsi:type="xsd:string">consumervision plus</listdescription>         <listversion xsi:type="xsd:integer">94</listversion>       </datalist>       <datalist>         <listid xsi:type="xsd:string">morthot </listid>         <listdescription xsi:type="xsd:string">mortgage hotlines</listdescription>         <listversion xsi:type="xsd:integer">206</listversion>       </datalist>       <datalist>         <listid xsi:type="xsd:string">mrtgbase</listid>         <listdescription xsi:type="xsd:string">mortgage base</listdescription>         <listversion xsi:type="xsd:integer">94</listversion>       </datalist>       <datalist>         <listid xsi:type="xsd:string">supernew</listid>         <listdescription xsi:type="xsd:string">american new movers plus</listdescription>         <listversion xsi:type="xsd:integer">171</listversion>       </datalist>       <datalist>         <listid xsi:type="xsd:string">tsebus  </listid>         <listdescription xsi:type="xsd:string">tse business file</listdescription>         <listversion xsi:type="xsd:integer">38</listversion>       </datalist>     </datalists>   </getlistsresult> </n1:getlistsresponse>

is there way can wait until $output has value before moving on? when put isset($output) conditional can see variable never set. tried calling shell_exec() again inside conditional still nothing.

*edit: server has ip restrictions trying run code on machine not work same. / should error response though.

i had put java file in server env path. also, making absolute path /jdk1.6.0_14/bin/java soapclient4xg http://...... worked well.

actionscript 3 - TweenLite does not work with object -

-
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.
