在jbuilder里面怎么调试socket程序？

将client和server端的程序都放在一个工程里面，thinging in java里面的例子，先启动server端main函数，当运行到Socket socket = s.accept();服务器端程序就会阻塞，然后启动client端main函数，当调试到String str = in.readLine();时，jbuilder里面显示运行位置的状态条就没有了，往下也不知道该怎么调试了。下面是client和server端的源程序。

client:

package test9;

//: JabberClient.java
// Very simple client that just sends
// lines to the server and reads lines
// that the server sends.
import java.net.*;
import java.io.*;

public class JabberClient {
public static void main(String[] args)
throws IOException {
// Passing null to getByName() produces the
// special "Local Loopback" IP address, for
// testing on one machine w/o a network:
InetAddress addr =
InetAddress.getByName(null);
// Alternatively, you can use
// the address or name:
// InetAddress addr =
// InetAddress.getByName("127.0.0.1");
// InetAddress addr =
// InetAddress.getByName("localhost");
System.out.println("addr = " + addr);
Socket socket =
new Socket(addr, JabberServer.PORT);
// Guard everything in a try-finally to make
// sure that the socket is closed:
try {
System.out.println("socket = " + socket);
BufferedReader in =
new BufferedReader(
new InputStreamReader(
socket.getInputStream()));
// Output is automatically flushed
// by PrintWriter:
PrintWriter out =
new PrintWriter(
new BufferedWriter(
new OutputStreamWriter(
socket.getOutputStream())),true);
for(int i = 0; i < 10; i ++) {
out.println("howdy " + i);
String str = in.readLine();
System.out.println(str);
}
out.println("END");
} finally {
System.out.println("closing...");
socket.close();
}
}
} ///:~

server:

package test9;

//: JabberServer.java
// Very simple server that just
// echoes whatever the client sends.
import java.io.*;
import java.net.*;

public class JabberServer {
// Choose a port outside of the range 1-1024:
public static final int PORT = 8080;
public static void main(String[] args)
throws IOException {
ServerSocket s = new ServerSocket(PORT);
System.out.println("Started: " + s);
try {
// Blocks until a connection occurs:
Socket socket = s.accept();
try {
System.out.println(
"Connection accepted: "+ socket);
BufferedReader in =
new BufferedReader(
new InputStreamReader(
socket.getInputStream()));
// Output is automatically flushed
// by PrintWriter:
PrintWriter out =
new PrintWriter(
new BufferedWriter(
new OutputStreamWriter(
socket.getOutputStream())),true);
while (true) {
String str = in.readLine();
if (str.equals("END")) break;
System.out.println("Echoing: " + str);
out.println(str);
}
// Always close the two sockets...
} finally {
System.out.println("closing...");
socket.close();
}
} finally {
s.close();
}
}
} ///:~
