Ctrl + F4 doesn't close current tab on Firefox in KDE

Hi all,

This is a common problem for KDE newcomers. This is because of default value in KDE Global Keyboard Shortcuts. By default "Ctrl + F4" keyboard shortcut assign to "Switch to Desktop 4" action in KDE Global Keyboard Shortcuts and then if you have 4 virtual desktop (or more) in your KDE desktop, "Ctrl + F4" bring you to 4th desktop and if not it does not do anything !

To solve this problem (if it is a real problem for you like me), you have to assign another keyboard shortcut to "Switch to Desktop 4" action:

1. Open KDE Global Keyboard Shortcuts program.
2. From KDE component combo box select "KWin".
3. In the search text box type "switch to desktop".
4. Finally, in the search result lest, reassign another keyboard shortcut to "Switch to Desktop 4" action.

KDE Plasma and Applications 4.9 is very stable

Hi all,

I have installed several Linux distributions based on KDE on my machines, but i always had problem with KDE bugs (and also the ugly window which want to report the bug :-D).

I upgraded my Kubuntu 12.04 to KDE Plasma and Applications 4.9. It is one of the best KDE i have ever seen. I have not seen any bug yet and its performance is better that past.
Congratulation to KDE team for this fantastic release.

How to download NetBeans plugins manually !

Hi,

Sometimes you want to download NetBeans plugins from outside of NetBeans IDE for example for offline installation. for this purpose :

1. From menu, go to Tools -> Plugins.
2. In the last tab (setting), you will see a update centers list (on left side) e.g. "Certified Plugins"
3. You have to know your desire plugin is located in which update center.
4. select that update center from list (e.g. Certified Plugins) and then from right side click on the "Edit" button.
5. from the shown dialogue, copy text in URL text box (do not copy last part of URL, in this case "catalog.xml.gz", only copy the address of  xxx.gz file e.g. "http://updates.netbeans.org/netbeans/updates/7.2/uc/final/certified")
6. Now you can paste the URL in your browser and find your plugin in folders.

have a nice time.

Generate WSDL file and Web Service Client with jaxws-maven-plugin

Hi,

In this post i want to describe:

1. how to generate a WSDL file from the JAX-WS annotated class using jaxws-maven-plugin (jaxws:wsgen)
2. how to generate the Java client class files from the generated WSDL file using jaxws-maven-plugin (jaxws:wsimport)
    

Firstly you have to generate your WSDL file from JAX-WS annotated class (class that annotated with @WebService), for this purpose you can use jaxws-maven-plugin, this maven plugin has a goal with name "wsgen", you can configure your maven project so that generate WSDL file during build process:

    
        
                                .
                                .
                                .
            
                org.jvnet.jax-ws-commons
                jaxws-maven-plugin
                2.2
                
                    
                        SimpleWS
                        
                            wsgen
                        
                        
                            com.saeed.NewWebService
                            true
                            UTF-8
                            true
                            true
                        
                    
                    
                    
                        TestWS
                        
                            wsgen
                        
                        
                            com.saeed.TestWebService
                            true
                            UTF-8
                            true
                            true
                        
                    

                

                
                    
                        org.glassfish.extras
                        glassfish-embedded-all
                        3.1.1
                                        
                  
                    
                        com.sun.xml.ws
                        jaxws-tools
                        2.2.5
                    
                
            

        
    

Note that you have to repeat "execution" tag for each jax-ws class with different id. The WSDL file will generate in "target/generated-sources/wsdl" directory (you can see other configuration tag from this).

Then you have to use generated WSDL file to generate Java client class files . for this purpose you can use "wsimport" goal :

    
        
            
                org.codehaus.mojo
                jaxws-maven-plugin
                1.10
                
                    
                        
                            wsimport
                        
                        
                            
                                ../saeed-web/target/generated-sources/wsdl
                            
                            
                                NewWebService.wsdl
                            
                            http://saeed-linux:8080/saeed-web/NewWebService?wsdl
                        
                        wsimport-generate-NewWebService
                        generate-sources
                    
                
                
                    
                        javax.xml
                        webservices-api
                        1.4
                    
                
                
                    ${project.build.directory}/generated-sources/jaxws-wsimport
                    false
                    true
                    true
                
            
        
    
    
        
            com.sun.xml.ws
            webservices-rt
            1.4
            provided
        
        
            junit
            junit
            3.8.1
            test
        
    

Now you can use codes which are generated into "sourceDestDir" to call web service method in your client application.

Sample chat application using NIO

Hi,
Programming with NIO API is very hard and complicate than traditional blocking IO (streams) in java.  I found a good sample in the web that easily demonstrate java NIO features using a chat application.
