Use HttpClient to simulate the browser login site, and then you can do things, such as publishing information, etc.First step : Get the actual post URL (without considering the complexity of the case) 1, need to use the Httpfox plug-in to Firefox, Httpfox clear a bit, and then start to capture2, switch back to the page login page, start to enter their own account password login, log in successfully after the cut back to Httpfox stop, see the recent P
In the Java Web development process, especially in the background development often need to see the browser debugging network items: Today in the development of online preview system using the Flexpaper plug-in, This plugin will call flexpaperviewer.swf this software (let's say so), this software processing is. swf file,The content-type that should be configured in the Tomcat Web. xml file is Application/x-
Look directly at the code:Method One:
Copy Code code as follows:
Runtime.getruntime (). EXEC ("rundll32 Url.dll,fileprotocolhandler http://www.jb51.net");
Method Two:
Copy Code code as follows:
Determine if the current system supports Java AWT Desktop extensions
if (java.awt.Desktop.isDesktopSupported ()) {
