  • Difference between classpath and endorsed directory

    - by Henrik
    Does anyone know what the difference is between adding an appropriate JAR-file (eg. Apache XALAN) to a JRE's endorsed directory and adding it to the application's classpath? Is it possible to take a jar-file that can be added to the endorsed lib and instead add it to the classpath?

  • Client for restful web service

    - by Ish
    I'd like to create a http-centric client for a restful web service created using CXF. To that end: Does any one know the (maven) dependencies for ONLY the CXF clients (Proxy & HTTP)? Is there any advantage to using CXF's built-in clients over say, Apache HttpClient?

  • Where can I find a web-project "security checklist?"

    - by iaagty
    I'm looking for a complete list of security guidelines for programming and deploying PHP web sites and applications on an Apache (Linux) server. Basically, a "security check list" to run through before finishing a project. I.e., Cross Site Scripting Cross Site Request Forgery Sanitize form data that goes into database Disable register globals and error reporting in custom php.ini Upload files below web root ...(the list goes on) I did some searching on the internet and in this forum, but couldn't find a comprehensive, succinct, and complete list of guidelines. Thanks in advance.

  • How to test unescaped &nbsps; as a whitespace

    - by gleery
    I use apache common lang to unescape a block of html text which contains &nbsp;, I want to filter out blocks that contains only whitespaces. But I can't test the   as a whitespace. It's not in the normal whitespace list(http://en.wikipedia.org/wiki/Whitespace_character), and I try to print its Hex form by calling Character.getNumericValue which return -1. &nbsp should be a whitespace,isn't? But How can I test it?

  • Nesting arbitrary objects in Java

    - by user1502381
    I am having trouble solving a particular problem in Java (which I did not find by search). I do not know how to create a nested lists of objects - with a different type of object/primitive type at the end. For example: *Note: only an example. I am actually doing this below with something other than Employee, but it serves as simple example. I have an array of an object Employee. It contains information on the Employee. public class Employee { int age int salary int yearsWorking public Employee () { // constructor... } // Accessors } What I need to do is organize the Employees by quantiles/percentiles. I have done so by the following: import org.apache.commons.math.stat.descriptive.rank.Percentile; public class EmployeeSort { public void main(String args[]) { Percentile p = new Percentile(); Employee[] employeeArray = new Employee(100); // filled employeeArray double[] ageArray new double[100]; // filled ageArray with ages from employeeArray int q = 25; // Percentile cutoff for (int i = 1; i*q < 100; i++) { // assign percentile cutoff to some array to contain the values } } } Now, the problem I have is that I need to organize the Employees first by the percentiles of age, then percentiles of yearsWorking, and finally by percentiles of salary. My Java knowledge is inadequate right now to solve this problem, but the project I was handed was in Java. I am primarily a python guy, so this problem would have been a lot easier in that language. No such luck.

  • Why does Python sometimes upgrade a string to unicode and sometimes not?

    - by samtregar
    I'm confused. Consider this code working the way I expect: >>> foo = u'Émilie and Juañ are turncoats.' >>> bar = "foo is %s" % foo >>> bar u'foo is \xc3\x89milie and Jua\xc3\xb1 are turncoats.' And this code not at all working the way I expect: >>> try: ... raise Exception(foo) ... except Exception as e: ... foo2 = e ... >>> bar = "foo2 is %s" % foo2 ------------------------------------------------------------ Traceback (most recent call last): File "<ipython console>", line 1, in <module> UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-1: ordinal not in range(128) Can someone explain what's going on here? Why does it matter whether the unicode data is in a plain unicode string or stored in an Exception object? And why does this fix it: >>> bar = u"foo2 is %s" % foo2 >>> bar u'foo2 is \xc3\x89milie and Jua\xc3\xb1 are turncoats.' I am quite confused! Thanks for the help! UPDATE: My coding buddy Randall has added to my confusion in an attempt to help me! Send in the reinforcements to explain how this is supposed to make sense: >>> class A: ... def __str__(self): return "string" ... def __unicode__(self): return "unicode" ... >>> "%s %s" % (u'niño', A()) u'ni\xc3\xb1o unicode' >>> "%s %s" % (A(), u'niño') u'string ni\xc3\xb1o' Note that the order of the arguments here determines which method is called!

  • What causes MSSQL to return the message 'The statement has been terminated'?

    - by Wally Lawless
    I have a very simple INSERT statement being executed from a PHP script running on a Linux Apache web server. I can run the query fine from within SQL Management Studio and it normally runs fine from PHP as well. However, every once in awhile I get an error message from my PHP script that the query failed and the mssql_get_last_message() function returns 'The statement has been terminated'. What sources can cause this message to be returned from MSSQL?

  • Programming texts and reference material for my Kindle DX, creating the ultimate reference device?

    - by mwilliams
    (Revisiting this topic with the release of the Kindle DX) Having owned both generation Kindle readers and now getting a Kindle DX; I'm very excited for true PDF handling on an e-ink device! An image of _Why's book on my Kindle (from my iPhone). This gives me a device capable of storing hundreds of thousands of pages that are full text search capable in the form factor of a magazine. What references (preferably PDF to preserve things such as code samples) would you recommend? Ultimately I would like reference material for every modern and applicable programming language (C, C++, Objective-C, Python, Ruby, Java, .NET (C#, Visual Basic, ASP.NET), Erlang, SQL references) as well as general programming texts and frameworks (algorithms, design patterns, theory, Rails, Django, Cocoa, ORMs, etc) and anything else that could be thought of. With so many developers here using such a wide array of languages, as a professional in your particular field, what books or references would you recommend to me for my Kindle? Creative Commons material a plus (translate that to free) as well as the material being in the PDF file format. File size is not an issue. If this turns out to be a success, I will update with a follow-up with a compiled list generated from all of the answers. Thanks for the assistance and contributing! UPDATE I have been using the Kindle DX a lot now for technical books. Check out this blog post I did for high resolution photos of different material: http://www.matthewdavidwilliams.com/2009/06/12/technical-document-pdfs-on-the-kindle-dx/

  • can i use hadoop cloudera without root access?

    - by in_the_cloud
    a bit of a binary question (okay, not excatly) - but was wondering if one is able to configure cloudera / hadoop to run at the nodes without root shell access to the node computers (although i can setup ssh passwordless login)? appears from their instructions that root access is needed, at yet i found a hadoop wiki which suggest root access might not be needed ? http://wiki.apache.org/nutch/NutchHadoopTutorial

  • Best practice for managing changes to 3rd party open source libraries?

    - by Jeff Knecht
    On a recent project, I had to modify an open source library to address a functional deficiency. I followed the SVN best practice of creating a "vendor source" repository and made my changes there. I also submitted the patch to the mailing list of that project. Unfortunately, the project only has a couple of maintainers and they are very slow to commit updates. At some point, I expect the library to be updated, and I expect that my project will want to use the upgraded library. But now I have a potential problem... I don't know whether my patch will have been applied to this future release of the 3rd party library. I also don't know whether my patch will even still be compatible with the internal implementation of the upgraded components. And in all likelihood, someone else will be maintaining my project by that point. Should I name the library in a special way so it is clear that we made special modifications (eg. commons-lang-2.x-for-my-project.jar)? Should I just document the patch and reference the SVN location and a link to the mailing list item in a README? No option that I can think of seems to be fool-proof in an upgrade scenario. What is the best practice for this?

  • Passwordless SSH using cgi-perl script

    - by AV
    Hello, This is my first shot at trying out cgi-perl scripts. I have SSH keys set up between my (root user) local machine and a remote machine. I'm trying to run a command on the remote box and display the output on a webpage hosted from my local machine. The script runs fine from command line however, it throws SSH key error when called from the webpage because the user running the script is apache and not root. Is there a way to get around this issue?

  • user specifc maven settings in repository

    - by Samuel
    http://maven.apache.org/settings.html As per documentation the user specific settings can be either copied to the .m2 folder or under the maven installation. If a developer changes a machine or gets a new user id, such properties have to be copied manually to these newer machines. Would it be possible to store user specific setting information in the repository itself (say SVN) and somehow have the mvn scripts load it on startup.
