Body
I have three Jar files.All jar files contain Same class TestServicesImpl And Same Method displayWeLcomeMessage() But having different messages(output) of displayWeLcomeMessage(). Example : <pre><code>public void displayWeLcomeMessage() { System.out.println("wecome msg of JAR version first"); } public void displayWeLcomeMessage() { System.out.println("wecome msg of JAR version two"); } public void displayWeLcomeMessage() { System.out.println("wecome msg of JAR version third"); } </code></pre> I have One main application and it contains jars included. My main application calls displayWeLcomeMessage() method. first JAR is added in classpath and second JAR is loaded with custom classloader and invoke method displayWeLcomeMessage(). <pre><code> File file = new File("C:/Users/amitk/Desktop/Test_1.0.2.jar"); @SuppressWarnings("deprecation") URL url = file.toURL(); URL[] urls = new URL[]{url}; URLClassLoader loader = new URLClassLoader(urls); Class classS = loader.loadClass("com.amit.servicesImpl.TestServicesImpl"); Object object = classS.newInstance(); Method getmsg = classS.getMethod("displayWeLcomeMessage"); getmsg.invoke(object); </code></pre> but it displays the same message as in method of JAR first. In my third JAR, i have changed the package name. that is com.amit.servicesImpl.TestServicesImpl is changed to com.amit.servicesImpl2.TestServicesImpl and this time it works properly that is message of method of JAR 3 is displayed here. so let me know the main issue behind this.and solution for this.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
