我将一个Ejb对象（ConverEjb）部署成功了。然后我写了一个测试该Ejb对象的junit类。我在junit类的setup方法中创建Ejb对象的调用，但运行junit测试时报错。我的junit类的文件名为EjbTest.java内容如下：
import junit.framework.*;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.rmi.PortableRemoteObject;
import java.math.BigDecimal;

public class EjbTest extends TestCase {

protected BigDecimal ExpectedValue;
protected BigDecimal param;
protected BigDecimal AMount;

public EjbTest(String name) {
super(name);
}

public void TestMyEjb() {

}

protected void setUp() {
ExpectedValue = new BigDecimal ("1216.00");
param = new BigDecimal ("10.00");
AMount = new BigDecimal ("10.00");
try {
Context initial = new InitialContext();
Context myEnv = (Context)initial.lookup("java:comp/env");
Object objref = myEnv.lookup("ejb/SimpleConverter");
ConverterHome home = (ConverterHome)PortableRemoteObject.narrow(objref, ConverterHome.class);
Converter currencyConverter = home.create();
AMount=currencyConverter.dollarToYen(param);
} catch (Exception ex) {
System.err.println("Caught an unexpected exception!");
ex.printStackTrace();
}
}

protected void tearDown() {
System.exit(0);
}

public boolean equals(BigDecimal Excepted,BigDecimal Value2) {
return true ;
}

public static Test suite() {
//return new TestSuite(EjbTest.class);

TestSuite suite= new TestSuite();
suite.addTest(new EjbTest("testdollarToYen"));
return suite;

}

public void testdollarToYen() {
assertEquals(ExpectedValue, AMount);
}
}

报错内容为：

Posted by: charleszq Posted on: 2003-10-14 14:54 As my point of view, this is nothing to do with JUnit. Please check the JNDI name of your bean. BTW, the method in your TestCase 'TestMyEjb' is not correct, you should rename the name to testMyEjb.

Posted by: floater Posted on: 2003-10-16 22:38 There are two ways to set up your data: 1. Use ANT in conjunction with JUNIT (You really should use catcus for EJB ). Check the book, java extreme tool. 2. Use TestSetup class in JUNIT, check JUNIT doc. It will run once and only once during the entire test run.
