Adding maven into eclipse resolved this error.

From the error it looks like there is no method configure for Configuration object. Check the javadocs https://docs.oracle.com/javase/9/docs/api/index.html?javax/security/auth/login/Configuration.html
I have followed exact instructions from the link eclipse-jcde, and now I have all JCDE features in my eclipse (I'm using eclipse ver 4.3.1). I made a new java card project and added new applet file to it, but when I try to run the project it shows below error:
Error occurred during initialization of VM
java/lang/NoClassDefFoundError: java/lang/String
and this is my (empty!) code:
package myPackage;
import javacard.framework.APDU;
import javacard.framework.Applet;
import javacard.framework.ISOException;
public class MyApplet extends Applet {
private MyApplet() {
}
public static void install(byte bArray[], short bOffset, byte bLength)
throws ISOException {
new MyApplet().register();
}
public void process(APDU arg0) throws ISOException {
// TODO Auto-generated method stub
}
}
what should I do?

i have simple added the class of this example in my app and i create a new PsTable in my gwt client class.
GWT Incubator's latest release is only compatible with GWT 2.1, and you're apparently using GWT 2.3 or later (the Could not find an exact match rule. Using 'closest' rule… was added in 2.3 to support IE9). Add to that that GWT 2.2 breaks binary compatibility of generators (they have to be recompiled against GWT 2.2 or later) and you have a good reason for a failure.
From the GWT Incubator homepage, you should be able to replace PaagingScrollTable uses with GWT 2.4's DataGrid. It's admittedly a much different approach (cells vs. widgets) but it's the way to go nowadays: GWT Incubator is deprecated (for good reasons) and you really shouldn't use it, move away from it if your project used it, and absolutely do not start using it in new projects.
BTW, the article you link to is 3 years old. You can't expect anything good from such ancient code snippets.
I am new to ANT and JUnit. As per the requirement i created 'JUnitTestCase' in Eclipse and call the requested test classes as per proper annotation.
While running the 'build.xml' file through 'Ant Build', it throws error as:

Buildfile: D:\ecllipse\eclipse\JunitTestProject\build.xml
setClassPath:

While looking back to JUnitTEstCase, i have imported the annotations like (import org.junit.After;import org.junit.Before and import org.junit.Test;). I, also, set build path for 'junit.jar'. I tried lot but couldn't figure it out. i am also attaching JUnitTest project as:
package jnuittestPckg;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
public class HelloWorldTest {
private HelloWorld hlwrd;
#Before
public void setUp() throws Exception {
hlwrd = new HelloWorld();
System.out.println("I am in Before");
}
#After
public void tearDown() throws Exception {
System.out.println("I am in After");
}
#Test
public void testClass1() {
hlwrd.Class1(null);
}
#Test
public void testClass2() {
hlwrd.Class2(null);
}
}
Please help me out.
You test.classpath property does not include the junit.jar.
Add it to the classpath and this issue will be resolved.
