I am using Glassfish-bundled Eclipse IDE. I wrote a simple EJB application. but it doesn't work. <pre><code>@Stateless @Remote(CalculatorRemote.class) @Local(CalculatorLocal.class) public class Calculator implements CalculatorRemote, CalculatorLocal { @Override public String sayHello(String name) { System.out.println("ejb:"+name); return null; } } ---- @Remote public interface CalculatorRemote { public String sayHello(String name); } ------- @Local public interface CalculatorLocal { public String sayHello(String name); } </code></pre> I wrote a standalone client to test, but failed. can't find JNDI. <pre><code>public class Main { public static void main(String[] args) throws Exception { InitialContext ctx = new InitialContext(); CalculatorRemote bean = (CalculatorRemote) ctx.lookup("java:global/TestEAR/TEjb/Calculator!com.CalculatorRemote"); bean.sayHello("Billy Bob"); } } </code></pre> In the server log, it said <pre><code>INFO: Portable JNDI names for EJB Calculator : [java:global/TestEAR/TEjb/Calculator!com.CalculatorRemote, java:global/TestEAR/TEjb/Calculator!com.CalculatorLocal] INFO: Glassfish-specific (Non-portable) JNDI names for EJB Calculator : [com.CalculatorRemote, com.CalculatorRemote#com.CalculatorRemote] </code></pre> Also, I have tried <pre><code>ctx.lookup("com.CalculatorRemote") </code></pre> still doesn't work. error message is <pre><code>java.lang.NullPointerException at com.sun.enterprise.naming.impl.SerialContext.getRemoteProvider(SerialContext.java:297) at com.sun.enterprise.naming.impl.SerialContext.getProvider(SerialContext.java:271) at com.sun.enterprise.naming.impl.SerialContext.lookup(SerialContext.java:430) at javax.naming.InitialContext.lookup(InitialContext.java:392) at com.Main.main(Main.java:9) Exception in thread "main" javax.naming.NamingException: Lookup failed for 'java:global/TestEAR/TEjb/Calculator!com.CalculatorRemote' in SerialContext [Root exception is javax.naming.NamingException: Unable to acquire SerialContextProvider for SerialContext [Root exception is java.lang.NullPointerException]] at com.sun.enterprise.naming.impl.SerialContext.lookup(SerialContext.java:442) at javax.naming.InitialContext.lookup(InitialContext.java:392) at com.Main.main(Main.java:9) Caused by: javax.naming.NamingException: Unable to acquire SerialContextProvider for SerialContext [Root exception is java.lang.NullPointerException] at com.sun.enterprise.naming.impl.SerialContext.getProvider(SerialContext.java:276) at com.sun.enterprise.naming.impl.SerialContext.lookup(SerialContext.java:430) ... 2 more Caused by: java.lang.NullPointerException at com.sun.enterprise.naming.impl.SerialContext.getRemoteProvider(SerialContext.java:297) at com.sun.enterprise.naming.impl.SerialContext.getProvider(SerialContext.java:271) ... 3 more </code></pre> Please help me.

Guidance

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.
