System.exit()

十二月 27, 2015

Exit code is 0 when execution went fine; 1 , -1 , whatever != 0 when some error occurred, you can use different values for different kind of errors. If I'm correct exit codes used to be just positive numbers (I mean in UNIX) and according to range: 1-127 are user defined codes (so generated by calling exit(n) ) 128-255 are codes generated by termination due to different unix signals like SIGSEGV or SIGTERM The following codes are from http://www.opensource.apple.com/source/Libc/Libc-320/include/sysexits.h.

Using setInfoWindowStyle("MVInfoWindowStyle2",...) in Oracle Mapviewer, setInfoWindowTitle() is invalid.

十二月 07, 2015

There is an issue in oraclemaps.js of Oracle Fusion Middleware MapViewer Version 11g ps6 (11.1.1.7.1). When the value of the parameter style is "MVInfoWindowStyle2" in the function MVThemeBasedFOI.setInfoWindowStyle(style, styleParameters), the function MVThemeBasedFOI.setInfoWindowTitle does not work. So must re-write the part of oraclemaps.js, the codes are the following MVThemeBasedFOI.prototype.setInfoWindowTitle = function (x90) { this._f320 = x90; MVInfoWindowStyle2.Title=x90; } MVInfoWindowStyle2.addContent = function (x5) { try{ if(this.Title!=undefined){ x5.childNodes[0].childNodes[0].childNodes[0].childNodes[0].childNodes[1].childNodes[0].childNodes[0].childNodes[0].innerHTML=this.Title; } }catch(e){ try{ x5.childNodes[0].childNodes[0].childNodes[0].childNodes[0].childNodes[0].childNodes[0].childNodes[0].childNodes[0].innerHTML=this.Title; }catch(e){} } x5.style.left = MVUtil._f26(55); x5.style.top

Showing a XML

十月 27, 2015

The following has 2 ways for indenting to show the xml. 1. using the class TransformerFactory's setAttribute("indent-number", new Integer(20)); 2. using the class Transformer's setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "2"); This way is higher priority than the first way. // Requires Java SE 1.7.0 TransformerFactory tf = TransformerFactory.newInstance(); //1. set the indented format of the additional whitespace when outputting the result tree; tf.setAttribute("indent-number", new Integer(20)); // It works. Transformer transformer = tf.newTransformer(); //2. set the indented format of the additional whitespace when outputting the result tree; This way is higher priority than the 1. transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "2"); //OutputKeys.INDENT, indent specifies whether the Transformer may a

Blocked plug-ins & Chrome

八月 27, 2015

Blocked plug-ins Google Chrome blocks plug-ins that are outdated or those that are not widely used because they can occasionally be a security risk. Plug-ins help browsers process special types of web content, like Flash or Windows Media files. Some plug-ins, such as Flash, are used by many websites on the Internet. Other plug-ins are only used by a small number of sites. Examples of plug-ins that Chrome blocks: Java RealPlayer QuickTime Shockwave Windows Media Player Adobe Reader prior to Adobe Reader X Unity Google Update VLC Run blocked plug-ins You can run some plug-ins even if they are blocked by Chrome. Chrome will ask you for permission to run a plug-in and you should only run plug-ins on sites that you trust. To let the plug-in run on the site, follow these steps: To run the plug-in just this once, click Run this time . The plug-in will run, but if you visit the site later, you'll be asked for permission to run the plug-in again. To always allow

Underscore.js Backbone.js

八月 27, 2015

Underscore is a JavaScript library that provides a whole mess of useful functional programming helpers without extending any built-in objects. It’s the answer to the question: “If I sit down in front of a blank HTML page, and want to start being productive immediately, what do I need?” … and the tie to go along with jQuery 's tux and Backbone 's suspenders. http://underscorejs.org/ Backbone.js gives structure to web applications by providing models with key-value binding and custom events, collections with a rich API of enumerable functions, views with declarative event handling, and connects it all to your existing API over a RESTful JSON interface. http://backbonejs.org http://www.quora.com/What-JavaScript-framework-does-Flow-use-for-its-web-frontend - jQuery for DOM manipulation - Underscore.js for awesome, rock solid, and progressive utility - A heavily modified Backbone.js for the model

Using JConsole

五月 29, 2015

JConsole (Java™ Monitoring and Management Console) is a graphical tool which allows the user to monitor and manage the behavior of Java applications. JConsole is a Swing application. You might find that running JConsole on the same workstation as the Java application you want to monitor affects the performance of your Java application. You can use JConsole to connect to a JVM running on a remote workstation to reduce the affect of running JConsole on the application performance. http://www-01.ibm.com/support/knowledgecenter/SSYKE2_8.0.0/com.ibm.java.zos.80.doc/diag/tools/JConsole.html

Double.NaN Float.NaN

五月 25, 2015

Double.NaN Float.NaN double i = 0.0/0.0; double i = Double.NaN; equals http://docs.oracle.com/javase/7/docs/api/java/lang/Double.html public boolean equals( Object obj) Compares this object against the specified object. The result is true if and only if the argument is not null and is a Double object that represents a double that has the same value as the double represented by this object. For this purpose, two double values are considered to be the same if and only if the method doubleToLongBits(double) returns the identical long value when applied to each. Note that in most cases, for two instances of class Double , d1 and d2 , the value of d1.equals(d2) is true if and only if d1.doubleValue() == d2.doubleValue() also has the value true . However, there are two exceptions: If d1 and d2 both represent Double.NaN , then the equals method returns true , even though Double.NaN==Double.NaN has the value false . If d1

the tips of the bar chart in wijmo 3

1. Hide the label on each bar var _chartLabels = $("#wijbarchartPro").wijbarchart().data().fields.chartElements.chartLabels; $.each(_chartLabels, function (index, elem) { if((index%2)==1){elem.attr('text', '');} }); 2. rotation label on bar chartLabelStyle: {rotation: 90}, 3. You can get the path element of the axis using the following properties : xaxis = $(“#wijbarchart”).wijbarchart().data().wijbarchart.axisEles[0].attrs.path[0]; yaxis = $(“#wijbarchart”).wijbarchart().data().wijbarchart.axisEles[0].attrs.path[1]; 4. The chartLabels[index].attrs.x and chartLabels[index].attrs.y return the positiong of the label. For instance, to get the position of first label upi may use the following js : var x = $(“#wijbarchart”).wijbarchart().data().fields.chartElements.chartLabels[0].attrs.x; var y = $(“#wijbarchart”).wijbarchart().data().fields.chartElements.chartLabels[0].attrs.y; 5.Change Bar Color mou
