How to set all locale settings in Ubuntu

- by Christian Schneider

A remote installed application has some encoding problems and on my local machine it is running fine. What is the best way to "copy" my locales to the remote machine? The locales on my personal machine are configured like this: $ locale LANG=de_DE.UTF-8 LANGUAGE=de_DE:en LC_CTYPE="de_DE.UTF-8" LC_NUMERIC=en_US.UTF-8 LC_TIME=en_US.UTF-8 LC_COLLATE="de_DE.UTF-8" LC_MONETARY=en_US.UTF-8 LC_MESSAGES="de_DE.UTF-8" LC_PAPER=en_US.UTF-8 LC_NAME=en_US.UTF-8 LC_ADDRESS=en_US.UTF-8 LC_TELEPHONE=en_US.UTF-8 LC_MEASUREMENT=en_US.UTF-8 LC_IDENTIFICATION=en_US.UTF-8 LC_ALL=

SüdLeasing reduziert mit e-Lease auf SOA-Basis Verwaltungskosten um über 1,5 Mio. Euro

- by franziska.schneider(at)oracle.com

Mit dem SüdLeasing Projekt e-Lease (electronic leasing process) wurde laut Dr. Buchacker eine maßgeschneiderte, exzellent ausbaufähige „Zukunftsplattform" geschaffen. Die Geschäftsprozesse des Unternehmens wurden gemeinsam mit Oracle und dem langjährigen Oracle Partner PROMATIS auf der neuen Plattform einheitlich abgebildet und verschlankt. Dabei wurden auch bestehende Legacy-Systeme einbezogen. Heute werden auf dieser Oracle basierten service-orientierten Architektur (SOA) die betrieblichen Abläufe automatisiert, optimiert und flexibel weiterentwickelt. Zunächst stand das Finanzdienstleistungsunternehmen vor der Herausforderung unternehmensweit die Durchlaufzeiten, die Kooperation und den Service durch Business Process Streamlining zu verbessern. Neben Einsparungen bei Aktenordnern, Ablagematerialien und bei der Archivierung sollten vor allem die Abteilungen „Markt" und „Marktfolge" mittels einer durchgängigen IT-Unterstützung der Arbeitsabläufe besser ineinander greifen. Parallel dazu beabsichtigte man durch sukzessive Entlastung der Mitarbeiter in den drei Haupt- und Bearbeitungsstandorten sowie in den 19 Vertriebsniederlassungen zusätzliche Kapazitäten zu gewinnen. Bereits kurz nach der Einführung von e-Lease in 2008 hatten sich die Verwaltungskosten in der SüdLeasing Zentrale um rund 1,5 Mio. Euro reduziert. Link zur kompletten Kundenreferenz Oracle und PROMATIS haben mit den im Projekt eingesetzten Oracle Produkten, dem Know-how und Engagement der Berater maßgeblich zum Erfolg von e-Lease beigetragen." - Dr. Ullrich Buchacker, Direktor und Abteilungsleiter IT/Organisation, SüdLeasing GmbH.

Finding the XPath with the node name

- by julien.schneider(at)oracle.com

A function that i find missing is to get the Xpath expression of a node. For example, suppose i only know the node name <theNode>, i'd like to get its complete path /Where/is/theNode. Using this rather simple Xquery you can easily get the path to your node. declare namespace orcl = "http://www.oracle.com/weblogic_soa_and_more"; declare function orcl:findXpath($path as element()*) as xs:string { if(local-name($path/..)='') then local-name($path) else concat(orcl:findXpath($path/..),'/',local-name($path)) }; declare function orcl:PathFinder($inputRecord as element(), $path as element()) as element(*) { { for $index in $inputRecord//*[local-name()=$path/text()] return orcl:findXpath($index) } }; declare variable $inputRecord as element() external; declare variable $path as element() external; orcl:PathFinder($inputRecord, $path) With a path <myNode>nodeName</myNode> and a message <node1><node2><nodeName>test</nodeName></node2></node1> the result will be node1/node2/nodeName This is particularly useful when you use the Validate action of OSB because Validate only returns the xml node which is in error and not the full location itself. The following OSB project reuses this Xquery to reformat the result of the Validate Action. Just send an invalid xml like <myElem http://blogs.oracle.com/weblogic_soa_and_more"http://blogs.oracle.com/weblogic_soa_and_more"> <mySubElem> </mySubElem></myElem> you'll get as nice <MessageIsNotValid> <ErrorDetail nbr="1"> <dataElementhPath>Body/myElem/mySubElem</dataElementhPath> <message> Expected element 'Subelem1@http://blogs.oracle.com/weblogic_soa_and_more' before the end of the content in element mySubElem@http://blogs.oracle.com/weblogic_soa_and_more </message> </ErrorDetail> </MessageIsNotValid> Download the OSB project : sbconfig_xpath.jar Enjoy.

The service bus console allows you to view the content that you reported. To report data you simply use the Report action in your proxy. The action itself is rather straightforward. You specify the content to report ($body for example), an optional key for easier search (for example the id of the record) and that's it. Sometimes though, what you want to is a bit more complicated. I recently had a case where the key was built from the message type (XML) and the id of the message. Seems quite simple but the id could be any element anywhere in the message depending on its type. This could be handled by 'if' statement but adding new cases would mean changing the proxy service and if you have lots of message types this can get boring so I wanted the solution to be as dynamic as possible (read "just change a configuration file and that's it"). The following entry details how you can make this dynamic in your proxy by using XQuery/XSLT. First step the XQuery We're going to use an XQuery to make the mapping between the XML message type and the location of the identifier in it. We assume here that the message type is the first node of the input XML and use a rather simple Xpath to find the identifier. The XQuery looks like this for two messages : <reportmapping> <row> <logical>messageType1</logical> <type>MT1</type> <reportingreferencelocation>//customID</reportingreferencelocation> </row> <row> <logical>messageType2</logical> <type>MT2</type> <reportingreferencelocation>//theOtherIDLocation</reportingreferencelocation> </row> </reportmapping> Second step the XSLT To get the identifier value of the dynamic path, we're going to use an XSLT transformation. This XSLT takes an XML parameter as input which contains our xpath (coming from the previous XQuery). The XSLT looks like this : <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xalan="http://xml.apache.org/xalan"> <xsl:param name="PathToNode"/> <xsl:template match="/"> <IDVALUE> <xsl:value-of select="xalan:evaluate($PathToNode/reportingreferencelocation)"/> </ IDVALUE > </xsl:template> </xsl:stylesheet> (note the use of a xalan function here. Xalan is the XSLT processor used in weblogic server) Last step, the proxy service We're now going to wire everything in the proxy service. First we assign the XQuery to a variable. We then get the entry in the XQuery corresponding to the record we're treating. We're then extracting the id of the message using the XSLT transformation Final assign is to built the final variable that will be used as the reporting key. The report action is then called with this variable. Everything is setup. We're now ready to test. Testing the solution Using the test console, we're sending our first XML ... <messageType1> <sender>test console 1</sender> <customID>ID12345</customID > <content> <field1>value of field 1</field1> </content> </messageType1> ... and a second one of another supported type <messageType2> <header> <theOtherIDLocation >ID67890</theOtherIDLocation > </header> <body> <data>Test data</data> </body> </messageType2> Reporting result is : Conclusion Report is done as expected. Now if a new message type must be supported we only have to modify the XQuery and nothing at the proxy service level. Sample project attached to this entry.sbconfig-dynamicReport.jar

When to write an explicit return statement in Groovy?

- by Roland Schneider

At the moment I am working on a Groovy/Grails project (which I'm quite new in) and I wonder whether it is good practice to omit the return keyword in Groovy methods. As far as I know you have to explicitly insert the keyword i.e. for guard clauses, so should one use it also everywhere else? In my opinion the additional return keyword increases readability. Or is it something you just have to get used to? What is your experience with that topic? Some examples: def foo(boolean bar) { // Not consistent if (bar) { return positiveBar() } negativeBar() } def foo2() { // Special Grails example def entitiy = new Entity(foo: 'Foo', bar: 'Bar') entity.save flush: true // Looks strange to me this way entity }

Aw, Snap! in Google Chrome [on hold]

- by D. S. Schneider

Just wondering if anyone else's experiencing the "Aw, Snap!" bug in Google Chrome. I'm developing a brand new engine which occasionaly triggers this bug and as far as I know, there's nothing one can do to find out what actually triggered the issue. I've also tested my engine with Firefox, which runs just fine. Anyway, just wanted to know if someone else is facing this while developing games for Google Chrome and has a clue about what can be done to avoid it. I'm using plain JavaScript and the audio and canvas elements from HTML5. Thanks!

[ADF tip #1] Working around some clientListener limitation

- by julien.schneider(at)oracle.com

As i occasionally work on Oracle ADF, i've decided to write tips on this Framework. Previous version of adf (10g) had a <afh:body> component to represent the body of your page which allowed to specify javascript events like onload or onunload. In ADF RC, the body (as well as html and head) is geneated by a single <af:document>. To implement the onXXXXX events you embed an <af:clientListener> within this <af:document> and specify property type="load" with the method to trigger. Problem is that onunload property is not supported by th af:clientListener. So how do i do ? Well, a solution is to add this event during page load. First step : Embed in your <af:document> the following : <af:clientListener type="load" method="addOnUnload()"/> Second step : Add your unload event using this kind of script : <af:document> <f:facet name="metaContainer"> <f:verbatim> <script type="text/javascript"> function addOnUnload(evt) { window.onunload=function() { alert('Goodbye Word'); } } </script> </f:verbatim> When closing browser your event will be triggered as expected.

Playing repeated sound in Java

- by Diogo Schneider

I'm trying to play sounds in a Java game with the following code: AudioStream audioStream = new AudioStream(stream); AudioPlayer.player.start(audioStream); The stream variable is just an InputStream to the resource. By the first time this code is called, the sound is played as expected, but by the second time the program just hangs, not even an exception is thrown. I don't know what's going on or how to prevent this. If I try closing either stream or audioStream after the above code, the program doesn't hang, but no sound is ever played at all. Any tips are welcome, thanks.

List of eCommerce sites that use end-to-end SSL?

- by Jon Schneider

My development team is considering implementing an eCommerce site using end-to-end SSL -- that is, every page on the site is accessed via an https:// URL -- rather than the more traditional "mixed mode" where most pages are accessed via http:// and only "secure" pages such as login and credit card entry are redirected to https://. Pros of doing such a "pure SSL" approach include avoidance of some session-hijacking attacks such as Firesheep; cons include performance considerations. My question is: Is anyone aware of a list of eCommerce websites (especially USA-based sites), or even specific websites, that use this end-to-end SSL approach? I'm especially interested in "regular" eCommerce sites rather than banks or other "financial" sites.

How to filter a character stream from an application using PowerShell?

- by Christian

A powershell question: I want to extract each line in a character stream produced by an application that matches a certain pattern which in pseudo-code would be something like this: PS <a_ps_command> <the_application_command_for_outputting_the_text_stream> | <my_filter > output_file.txt In my case the application is a CM-tool that outputs the change history of a source file and the (psuedo)pattern should be something like: <a couple of numbers><a name><a time stamp><a line of characters> Cheers, Christian

PHP extension causes symbol lookup error

- by Christian

Dear, I installed - or better tried to - the NMCryptGate Extension for PHP on my Debian 5.0.8 server. I did this by compiling the sources which came up with no error message. Calling phpinfo() I can see the extension as enabled. BUT, whenever I try calling a method from this extension I get an error logged to the apache error log: /usr/sbin/apache2: symbol lookup error: /usr/lib/php5/20060613+lfs/nmcryptgate.so: undefined symbol: nmlistalloc What is missing? I got two packages from the software company: the php module sources and some files which should - according to their path inside the tar - go to /usr/local/bin|doc|include|lib. I moved them there without any effect. Each of these two packages has its own config file almost looking the same: \# libnmcryptgate.la - a libtool library file \# Generated by ltmain.sh - GNU libtool 1.3.4 (1.385.2.196 1999/12/07 21:47:57) \# \# Please DO NOT delete this file \# It is necessary for linking the library \# The name that we can dlopen(3) dlname='' \# Names of this library library_names='libnmcryptgate.so.1 libnmcryptgate.so libnmcryptgate.so' \# The name of the static archive old_library='' \# Libraries that this one depends upon dependency_libs=' -L. -L/usr/ssl/lib -L/usr/local/ssl/lib -L/usr/local/lib -lssl -lcrypto' \# Version information for libnmcryptgate current=1 age=0 revision=29 \# Is this an already installed library installed=yes \# Directory that this library needs to be installed in libdir='/usr/local/lib' I tried several ways to get it right: moving files, symlinking, changing configurations - always followed by restarting apache - no success. I guess I just have to move the files to the correct location or change the libdir inside the config files but meanwhile I'm totally confused by the two packages: do I need both, which config rules what, do I have to use the libdir variable? And for what? ... Anybody out there hinting me to my source of failure? Thank you in advance, regards, Christian

Hi, I created a WPF application in Visual Studio 2010 Express (C#) and added the text below to the Application.Resources in App.xaml. I see the style applied to the window in the designer, but when I run the application, the window background is white. Running in Windows XP on BootCamp on a MacBook Pro if that is a factor. Thanks in advance, Christian <Style TargetType="{x:Type Window}"> <Setter Property="Background"> <Setter.Value> <LinearGradientBrush StartPoint="0,0" EndPoint="0,1"> <GradientStop Offset="0" Color="WhiteSmoke" /> <GradientStop Offset="1" Color="Silver" /> </LinearGradientBrush> </Setter.Value> </Setter> <Setter Property="Padding" Value="20" /> </Style>

manipulate objects outside svg with javascript-function inside the svg

- by Christian Benke

Hello! I'm embedding a svg-graphic on my website and i'd like to manipulate the rest of the website with javascript-commands which are in the svg - though i'm not sure if this is possible. Let me elaborate: I've got a worldmap in svg, i want to click on a country and this click should run an ajax-call and load relevant information of this country into a div in the html site where the svg is embedded. "onclick="location.href='xxx'"" redirects to the respective site which is fine, but i'd prefer to run a js-function that fetches the site with ajax - but running a javascript-function in the svg only seems to work for functions and elements defined in the svg, not outside of it. Is it basically possible to manipulate anything outside the svg through a js-function in the svg? How? Regards Christian

MS SQL and .NET Typed Dataset AllowDBNull Metadata

- by Christian Pena

Good afternoon, I am generating a typed dataset from a stored procedure. The stored procedure may contain something like: select t1.colA, t2.colA AS t2colA from t1 inner join t2 on t1.key = t2.key When I generate the typed dataset, the dataset knows whether t1.colA allows NULLs, but it always puts FALSE in AllowDBNull for t2.colA even if t2.colA allows NULL. Is this because the column is aliased? Is there any way, from SQL, to hint to VS that the column allows NULL? We currently have to go in and update the column's AllowDBNull if we regenerate the table. Thanks in advance. Christian

Get Angle to Tangent that Intersects Point

- by Christian Stewart

I have a circle around a given point, call this point (x1, y1). I know the radius of the circle around this point. I also have a second point (x2, y2), that is a distance away, outside the radius of the circle. I need a algebraic way through code to calculate the heading (angle from vertical) needed to intersect the circle at 90* to the center point (I.E. get the angle of the tangent intersecting line 2) around the point (x1, y1) from the second point (x2, y2) A bit of background: Essentially the two points are GPS coordinates on a 2D map, I need to know the target heading to intersect the circle in order to follow its path around the center point. Thanks! Christian

Why are perfectly legitamate pages on my website registering in google Webmasters as 404?

- by christian

I have seen this question asked several times here, but never clearly answered. I suspect it has something to do with my .htaccess file: # BEGIN WordPress <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> # END WordPress <IfModule mod_rewrite.c> RewriteEngine On RewriteRule ^moreinfo/(.*)$ http://www.kgstiles.com/moreinfo$1 [R=301] RewriteRule ^healthsolutions/(.*)$ http://www.kgstiles.com/healthsolutions$1 [R=301] RewriteRule ^(.*)\.html$ $1/ [R=301] RewriteRule ^(.*)\.htm$ $1/ [R=301] </IfModule> when I check the url without a forward slash at the end, it registers as 404 (even though it renders fine in a browser), but when I write it without the forward slash at the end, it renders 200 OK, but if I try to take off the forward slash with the htaccess file, the browser gives me a 310 error (too many redirects) you can see the 404 and 310 with this url: http://www.kgstiles.com/pureplantessentials.html which redirects to http://www.kgstiles.com/pureplantessentials/ (which is a 404), so what is a solution and why might this be registering as a 404? Any Help is appreciated! (I'm using wordpress btw)

Using Oracle ADF Data Visualization Tools (DVT) Line Graphs to Display Weather Information

- by Christian David Straub

OverviewA guest post by Jeanne Waldman.I have a simple JDeveloper Fusion application that retrieves weather data. I wanted to compare the week's temperatures of different locations in a graph. I decided to check out the dvt:lineGraph component, and it took me a few minutes to add it to my jspx page and supply it with data.Drag and Drop the dvt:lineGraph onto your pageI opened my .jspx page in design modeIn the Component Palette, I selected ADF Data Visualization.Then I dragged 'Line' onto my page.A dialog popped up giving me options of the type of line graph. I chose the default.A lineGraph displayed with some default data. Hook up your weather dataNow I wanted to hook up my own data. I browsed the tagdoc, and I found the tabularData attribute.Attribute: tabularDataType: java.util.ListTagDoc:Specifies a list of data that the graph uses to create a grid and populate itself. The List consists of a three-member Object array for each data value to be passed to the graph. The members of each array must be organized as follows: The first member (index 0) is the column label, in the grid, of the data value. This is generally a String. If the graph has a time axis, then this should be a Java Date. Column labels typically identify groups in the graph. The second member (index 1) is the row label, in the grid, of the data value. This is generally a String. Row labels appear as series labels in the graph (usually in the legend). The third member (index 2) is the data value, which is usually a Double.The first member is the column label of the data value. This would be the day of the week.The second member is the row label of the data value. This would be the location name.The third member is the data value, usually a Double. This would be the temperature. I already had all this information, I just needed to put it in a List with a three-member Object array for each data value. /** * This is used for the lineGraph to show the data for each location. */ public List<Object[]> getTabularData() { List<Object[]> tabularData = new ArrayList<Object []>(); List<WeatherForecast> weatherForecastList = getWeatherForecastList(); // loop through the list and build up the tabular data. Then cache it. for(WeatherForecast wf : weatherForecastList) { List<ForecastDay> forecastDayList = wf.getForecastDayList(); String location = wf.getLocation(); for (ForecastDay fday : forecastDayList) { String day = fday.getPrettyDate(); String highTemp = fday.getHighF(); tabularData.add(new Object[]{day, location, Double.valueOf(highTemp)}); } } return tabularData; } Now I bound the lineGraph to this method by setting tabularData to#{weatherForAllLocationsBean.tabularData}weatherForAllLocationsBean is my bean that is defined in faces-config.xml. Adding a barGraphIn about 30 seconds, I added a barGraph with the same data. I dragged and dropped a bar graph onto the page, used the same tabularData as I did in the line graph. The page looks like this: ConclusionI was very happy how fast it was to hook up my weather data to these graphs. They look great, and they have built in functionality. For instance, I can hide/show a location by clicking on the name of the location in the legend.
