  • Is there a way to launch an aggressive and complete garbage collection in Java?

    - by Gnoupi
    For memory optimization reasons, I'm launching myself the garbage collector during profiling, to check if objects are correctly cleaned after disposing of them. The call to garbage collector is not enough, though, and it seems that there is no guarantee of what it will clean. Is there a way to call it, to be sure it will recover as much as it can, in profiling conditions (this would have no point in production, of course)? Or is "calling it several times" the only way to be "almost sure"? Or did I simply misunderstand something about the Garbage Collector?

  • Grails web flow: Possible to include the state name in the url?

    - by Kimble
    I'm playing around with Google Analytics goals / funnels. I would like to use this to track a checkout process, but the web flow urls are formated in a way that makes this very hard. Would it be possible to change: http://localhost:8080/checkout/checkout?execution=e1s2 .. into something more like this: http://localhost:8080/checkout/checkout/shipping?execution=e1s2 or any thing else that would make them more trackable with Google Analytics?

  • Apache HTTPD as a proxy

    - by markovuksanovic
    I need to redirect all the requests from localhost:8080/app1/ to localhost/app1. which is the best way to do it. The only requirement is that the user must never be aware that he is accessing the application at port 80. i guess I need to set up Apache HTTPD proxying - I'm just not sure which is the best way to do it. Thanks in advance.

  • Getting the right result of mouse click event

    - by Jessy
    Hello, I'm curious why I got the "right" BUT "wrong"number of result when I click the mouse. I supposed to print on the console mouseClicked once everytimes the mouse is clicked. However I got many of them printed out everytimes I clicked the mouse ...sometimes 5 e.g. mouseClicked mouseClicked mouseClicked mouseClicked mouseClicked Instead of just mouseClicked Why? public void mouseClicked(MouseEvent arg0) { System.out.println("mouseClicked"); }

  • Java replace slow?

    - by cpf
    Hi StackOverflow, I have a Java application that makes heavy use of a large file, to read, process and give through to SolrEmbeddedServer (http://lucene.apache.org/solr/). One of the functions does basic HTML escaping: private String htmlEscape(String input) { return input.replace("&", "&amp;").replace(">", "&gt;").replace("<", "&lt;") .replace("'", "&apos;").replaceAll("\"", "&quot;"); } While profiling the application, the program spends roughly 58% of the time in this function, a total of 47% in replace, and 11% in replaceAll. Now, is the Java replace that slow, or am I on the right path and should I consider the program efficient enough to have its bottleneck in Java and not in my code? (Or am I replacing wrong?) Thanks in advance!

  • Rearrange array

    - by bradenkeith
    Array starts like this: Array ( [SMART Board] => Array ( [0] => sb1 [1] => sb2 [2] => sb3 ) [Projector] => Array ( [0] => pr1 [1] => pr2 [2] => pr3 ) [Speakers] => Array ( [0] => sp1 [1] => sp2 [2] => sp3 ) [Splitter] => Array ( [0] => spl1 [1] => spl2 [2] => spl3 ) [Wireless Slate] => Array ( [0] => ws1 [1] => ws2 [2] => ws3 ) ) The keys are used as my table columns titles. Their individual arrays are to carry the column information. I have split it up even further with array_slice and array_merge_recursive to look pretty as 2 arrays - 1 holds the column names, the other looks like this: Array ( [0] => sb1 [1] => sb2 [2] => sb3 [3] => pr1 [4] => pr2 [5] => pr3 [6] => sp1 [7] => sp2 [8] => sp3 [9] => spl1 [10] => spl2 [11] => spl3 [12] => ws1 [13] => ws2 [14] => ws3 ) However, when trying to write the table I'm getting keys 0, 1, 2 as the column data, then row break then 3, 4, 5 then row break... etc. I need it to be 0, 3, 6, 9, 12 row break 1, 4, 7, 10, 13 row break etc... How can I either rearrange my array to allow for this, or rewrite how the data goes into the table so that the correct information lines up with the appropriate column? foreach(unserialize($dl->data) as $data){ //first 3 are specialinstructions, system, and room $uniques = array_slice($data,0,3); $rows = array_slice($data,3); $rows2 = array_merge_recursive($rows2, $rows); //get the specialinstructions, system, and room foreach($uniques as $unique){ echo $unique."<br/>"; }///foreach uniques echo "<br>"; }///foreach unserialized $numberofrooms = count($rows2[key($rows2)]); $numberofproducts = count($rows2); print_r($rows2); unset($rows); //write the individual rows foreach($rows2 as $header=>$rowset){ $headers[] = $header; foreach($rowset as $row){ $rows[] = $row; }//foreach rowset }//foreach rows2 echo "<p>"; print_r($rows); echo '<table class="data-table"> <caption>DL</caption> <thead><tr>'; foreach($headers as $header){ echo "<th>".$header."</th>"; } echo '</tr></thead>'; echo '<tbody>'; $i = 0; foreach($rows as $row){ if($i == 3 || $i == 0){ echo "<tr>"; $i = 1; } echo '<td>'.$row.'</td>'; if($i == 2){ echo "</tr>"; } $i++; } echo '</tbody></table>';

Update: On reading this question on Experts-Exchange, tried gpresults. Output extract follows: COMPUTER SETTINGS The following GPOs were not applied because they were filtered out XADistribution Filtering: Denied (Security) Default Domain Policy Filtering: Denied (Security)

  • How to save webpage to string with cookies support (httpWebRequest)

    - by Maciej
    I need to read webpage and store its content in string for further processing. Sounds simply but I have problem with cookies support. Opened page says I need browser supporting cookies (or turned on). I've made method trying do that via httpWebRequest - which normally works to me but I've come to a standstill with those unfortunate cookies... Any idea how to make it working? Here is my method: string ReadHtml (string address, string encoding) { Uri url = new Uri(address); CookieContainer cookieContainer = new CookieContainer(); HttpWebRequest httpWebRequest = (HttpWebRequest)HttpWebRequest.Create(url); httpWebRequest.AllowAutoRedirect = true; httpWebRequest.KeepAlive = true; httpWebRequest.CookieContainer = cookieContainer; httpWebRequest.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727)"; httpWebRequest.Method = "GET"; HttpWebResponse webResponse = (HttpWebResponse)httpWebRequest.GetResponse(); // Code Page Encoding enc = Encoding.GetEncoding(encoding); // Read content StreamReader loResponseStream = new StreamReader(webResponse.GetResponseStream(),enc); string lcHtml = loResponseStream.ReadToEnd(); webResponse.Close(); loResponseStream.Close(); return lcHtml; }

  • IE6 https security message appearing after closing jQuery colorbox overlay

    - by RyanP13
    I am working on a secure site, https. I am using the colorbox jquery plugin to iframe another page from the same site over the current content. In IE6 when i close the colorbox overlay i get the following message: "This page contains both secure and nonsecure items. Do you want to display the nonsecure items?" Any ideas why this is happening? Can it be prevented? Assume i would have to make the whole site http rather than https but this is not possible as we have online payments.

  • Cloning java ArrayList and preventing it from modifications

    - by user222164
    I have a data structure like a database Rowset, which has got Rows and Rows have Columns. I need to initialize a Columns with null values, current code is to loop thru each column for a row and initialize values to NULL. Which is very inefficient if you have 100s or rows and 10s of column. So instead I am keeping a initialized ArrayList of columns are RowSet level, and then doing a clone of this Arraylist for individual rows, as I believe clone() is faster than looping thru each element. row.columnsValues = rowsset.NullArrayList.clone() Problem with this is NullArrayList can be accidentally modified after being cloned, thus sacrificing the integrity of ArrayList at RowSet level, to prevent I am doing 3 things 1) Delcaring ArrayList as final 2) Any elements I insert are final or null 3) Methods thurough this arrayList are passed to other arrays are declared a final. Sounds like a plan, do you see any holes ?

  • Virtualised Sharepoint Backup Strategies

    - by dunxd
    I have a Sharepoint (OSS 2007) farm running on three virtual machines in VMWare ESX, plus a SQL Server backend on physical hardware. During a recent Business Continuity Planning event I tried restoring the sharepoint farm with only the config and content databases, and failed to get things working. My plan was to build a new sharepoint server, then attach this to a restoration config database and install the Central Management site on this server, then reattach the content databases. This failed at the Central Management part of the plan. So I am back to the drawing board on the best strategy for backup and recovery, with reducing the time and complexity of the restore job the main objective. I haven't been able to find much in the way of discussion of backup/restore strategies for Sharepoint in a VMWare environment, so I figured I'd see if anyone on server fault has any ideas or experience.

  • Mac OS X bypass proxy for certain domains

    - by Brian
    In college I'm behind a proxy. When I try to visit one of my local Apache virtual hosts behind the proxy, then my college DNS attempts to resolve the host, thus bypassing my local host file. In the advanced setting for proxies you seem to be able to enter values into "Bypass proxy settings for these Hosts & Domains". I added the last 2 to the end - "*.local, 169.254/16, *.dev, *.sb". But it doesn't work. Is there a solution?
