Launching the eBay Java SDK API Calls Demo Sample Application from NetBeans 4.1

Building the Application

Select Build > Build Main Project, press F11, or right-click the project node and choose Build Project from the context menu.

Running the Application

Select Run > Run Main Project, press F6, or right-click the project node and choose Run Project from the context menu.

The project runs, however, you have to configure your account information every time you run the application, which can be quite tedious.

Let's fix that.

Create a Properties File to Hold Our Account Configuration Information

1. Select File > new File, press Ctrl + N, or right-click the project node and choose New > File/Folder...
2. Select Properties File from the Other Category and select Next.
3. Name the file keys and select Finish.
4. The key.prorties file opens in the editor. Add the following properties and update with your eBay credentials:

       devId = <enter you developer ID>
       appId = <enter your application ID>
       certId = <enter your certificate ID>
       token = <enter your token>
       apiServerUrl = https://api.sandbox.ebay.com/wsapi
       epsServerUrl = http://msa-e1.ebay.com/ws/eBayISAPI.dll?EpsBasicApp
                   

Read the Properties from the Application

1. Open FrameDemo.java
2. In the constructor, all the following code following the first line provided:

       ApiCredential cred = new ApiCredential();
   
       // Read properties file to load developer credentials
   Properties keys = new Properties();
       try {
           keys.load(new FileInputStream("keys.properties"));
       } catch (IOException e) {
           System.out.println(e);
       }
   
       cred.seteBayToken(keys.getProperty("token"));
       ApiAccount ac = cred.getApiAccount();
       ac.setDeveloper(keys.getProperty("devId"));
       ac.setApplication(keys.getProperty("appId"));
       ac.setCertificate(keys.getProperty("certId"));
                   

3. Press Alt + Shift + F to fix the missing imports.
4. Replace the hard-coded strings for API and EPS Server URLs with the following:

       this.apiContext.setApiServerUrl(keys.getProperty("apiServerUrl"));
       this.apiContext.setEpsServerUrl(keys.getProperty("epsServerUrl"));
                   

Build and Run the Application Again

Press F11 to build the application and F6 to run it. The API Account dialog is now properly configured. Select and API from the list box, such as GetSearchResults and press Run.

Note, if you are behind a corporate proxy and get a ConnectException, you can add the following two lines of code to the top of FrameDemo constructor:

System.setProperty("http.proxyHost", "<your proxy host>");
System.setProperty("http.proxyPort", "<your proxy port>");

Add a debug target to build.xml

1. Open build.xml
2. Scroll to the bottom of the file and add the following target:

    <target name="debug" depends="compile" description="Debug Project">
        <fail unless="netbeans.home">This target can only run inside the NetBeans IDE.</fail>
        <nbjpdastart name="Sample App" addressproperty="jpda.address" transport="dt_socket">
            <classpath refid="project.class.path"/>
            <sourcepath path="${src}"/>
        </nbjpdastart>
        <java fork="true" classname="apicallsdemo.ApiCallsDemo">
            <jvmarg value="-Xdebug"/>
            <jvmarg value="-Xrunjdwp:transport=dt_socket,address=${jpda.address}"/>
            <classpath refid="project.class.path"/>
        </java>
    </target>
            

Set a breakpint and Debug the Application

1. Click on the left margin on the FrameDemo.java to set a breakpoint.
2. Right-client the build.xml under the apiCallsDemo project node and run the debug target..
3. From here you can step though your application, viewing locale variables, setting watches, etc. See Debugging Applications for more information.
