InetAddress UnknownHostException
Hello,
InetAddress.getLocalHost() is throwing a UnknownHostException when i'm running an app from within another app using Runtime.exec() and the command string "cmd /k appname". However it returns the hostname fine when the app is run from the command prompt!
I'm guessing it's a environment veraiable or another configuration problem but have not been able to figure of what to missing so far.
Any help would be appreicated
Fixed the problem,
requires SystemRoot to be set

InetAddress.getLocalHost().getHostName() throwing unknownHostException
When i am executing this statement from a simple java program its working fine. But when I call the statement from JSP or servlet, its throwing UnknownhostException.
I am using tomcat3.3.1 as web server running on Sun Solaris.
Is there problem with setting of tomcat ???
Please help me out.I tried nslookup at the shell prompt. It was showing unknown host for the ip address. I contacted our network people and came to know that the server is on internet and thats why it was not showing the local ip address host name in nslookup. Then I tried the internet ip address and host name of the server in the stetement and it worked out. Hope i am clear to u. Now the statement is running fine.
Actually I was trying to send mail using Smtp class and while dong that it was throwing UnknownHostException. Then i found out the Intaddress.getLocalHost() was the stmt throwing this error. Now as I am giving the internet address for constructor of new SmtpClient() method, it is not giving this error and my mail is getting delivered. But it processis taking lot of time. It takes @ 15 minutes to send a mail.
Can u help me out in this????
Thanx for help....... -
I need help using Inet address to make a internet usage log viewer. I have found a program to change IP addresses to a site URL. However it is not working correctly. help to rectify this problem will be greatly appreciated.
Below is the code that i have thus far.
import java.net.*;
class Url001{
public static void main(String[] args){
try{
System.out.println(
"Get and display IP address of URL by name");
InetAddress address = InetAddress.getByName(
"www.hotmail.com");
System.out.println(address);
System.out.println(
"Do reverse lookup on the IP address");
//Extract the IP address from the string to the right
// of the /. Then provide the IP address as a string
// to the getByName() method.
int temp = address.toString().indexOf('/');
address = InetAddress.getByName(
address.toString().substring(temp+1));
System.out.println(address);
System.out.println(
"Get and display current IP address of LocalHost");
address = InetAddress.getLocalHost();
System.out.println(address);
System.out.println(
"Do reverse lookup on current " +
"IP address of LocalHost");
temp = address.toString().indexOf('/');
address = InetAddress.getByName(
address.toString().substring(temp+1));
System.out.println(address);
System.out.println(
"Get and display current name of LocalHost");
System.out.println(address.getHostName());
System.out.println(
"Get and display current IP address of LocalHost");
//Get IP address as an array of bytes.
byte[] bytes = address.getAddress();
//Convert IP address bytes to unsigned values
// and display separated by spaces.
for(int cnt = 0; cnt < bytes.length; cnt++){
int uByte =
bytes[cnt] < 0 ? bytes[cnt] + 256 : bytes[cnt];
System.out.print(uByte + " ");
}//end for loop
System.out.println();
}catch(UnknownHostException e){
System.out.println(e);
System.out.println("Must be online to run properly.");
}//end catch
}//end main
}//end class Url001 and this is the Expected output

InetAddress.getLocalHost retrieving 127.0.0.1, not the actual IP Address
I am using the following code :
try{
InetAddress iaddr = InetAddress.getLocalHost();
String ipaddr = iaddr.getHostAddress();
System.out.println("IP= "+ipaddr);
}catch(UnknownHostException ex){
ex.getMessage();
to get the IP address of the server on which this code is running.
We are actually trying to set up different machines (other than the Production machine) for Failover of the Application. So, we need to get the IP address of the machine on which the application is running in the code.
For one machine, the above code works perfectly OK.
But, for the three Production machines, the IP address that we are retrieving using the getLocalHost function is fetching the localhost and not the IP address of the machine. That is instead of fetching the IP � a.b.c.d (I am not writing the actual IP in this mail :) ) ... it is fetching the localhost 127.0.0.1 .
So we need to find out a way to fetch the actual IP address so that failover can work.
FYI, all of the machines are Solaris machines.

Getting a netative value from InetAddress...
I have an IP address that I am trying to convert to an InetAddress so I can pick out pieces of it. Unfortunately, when I use the following code, the first region of the IP address is a negative number... Am I doing something incorrectly? (I put in a dummy IP just for the sake of this post, BTW)
InetAddress address = null;
try {
address = InetAddress.getByName("131.255.255.255");
} catch (UnknownHostException uhe) {
System.out.println("Unknown Host " + ip);
System.out.println("address: " + address);
System.out.println("address.getAddress()[0]: " + (address.getAddress()[0]));
System.out.println("address.getAddress()[1]: " + (address.getAddress()[1]));
System.out.println("address.getAddress()[2]: " + (address.getAddress()[2]));
System.out.println("address.getAddress()[3]: " + (address.getAddress()[3]));
This is the output:
address: 131.255.255.255/131.255.255.255
address.getAddress()[0]: -125
address.getAddress()[1]: 255
address.getAddress()[2]: 255
address.getAddress()[3]: 255
Why is this showing up as -125 and not 131?0000 .... 1000 0011 = 131 int
cut to byte
1000 0011 = -125
prolly recast to int to get the right value...sorry, you know what I mean, not cast, since that'd keep the sign, put the 0's back -
UnknownHostException during OBPM Enterprise Setup
Hi,
when trying to configure the OBPM Enterprise while doing the WLST Script I get an UnknownHostException even though I can connect via WebLogic Scripting Console using the same host, port, username and password. Do I need something special for OBPM here?
I tried to use the hostname and the IP. Nslookup shows the correct domain resolution.

To correct the connection edited the t3 parts in:
<domain_home>/init-info/startscript.xml
Took off the alias for the host and set "localhost" instead.
Hope this helps. -

[weblogic.xml]Hi All,
I didn't have proxy client on my machine. That was causing this exception.
I installed proxy client and now, the web application deploys fine.

Unknownhostexception while connecting to webservice
Hi,
We have an application which connects to a webservice on a different box. If the webservice URL is accessed from the box itself, it works fine. But when we try to hit it from the application, it gives the following error:

The URL says as63alyn, but the error says unknownhostexception : stg-wlms3.genworth.net
I checked out and found that it might be a cache forever problem, so disabled the caching forever by changing the java.security file to have the value set to 0 instead of -1 and have the manage servers and the admin server restarted, but still the same problem.
Can you please suggest why it might be picking up the wrong name and giving me the unknownhostexception.
Let me know if any more information is required.
Regards,
Prashant Kale.I'm sure someone will reply to one of your two OTHER nearly identical threads.

InetAddress posting Unknown Host Exception
Hello,
I am relatively new to java and I am running into an Unknown Host Exception when attempting to return the IP's for valid host names. The strange part is that the first host name returns an address however every entry after the first returns the Unkown Host Exception. Here is the snippet of code that the problem is occuring in.
Inet address as declared earlier in the code:
private InetAddress Address = null;Code reporting errors:
StringBuffer sb0 = new StringBuffer();
int chr;
// Read until the end of the stream
while ((chr = inputStream0.read()) != -1)
sb0.append((char) chr);
String display = sb0.toString();
String temp = display.replace("Giant ", "g0");
String[] words = temp.split("\\|");
StringBuffer db = new StringBuffer();
for (int i=0; i < words.length; i++)
String many = (words[i] +"wu1");
try
Address = InetAddress.getByName(many);
db.append(words[i] + "wu1|" + Address);
catch(NullPointerException e)
db.append(words[i] + "wu1 - Null Pointer - ");
catch(UnknownHostException e)
db.append(words[i] + "wu1 - Unknown Host - ");
String yay = db.toString();
log.append(yay);
catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
catch (IOException e)
// TODO Auto-generated catch block
e.printStackTrace();
}I have attempted setting Address back to null after the address was appended but it didn't make any difference.
Edited by: mudbuggle on Aug 4, 2008 7:19 PMI made the adjustments however I am still experiencing the same problem.
www.yahoo.com returns an ip address but the rest return Unknown Host Exceptions.

Hi all
When compiling my program
Following errors getted:-
1.unreported exception java.net.UnknownHostException; must be caught or declared to be thrown
InetAddress inet = InetAddress.getByName("www.davidreilly.com");
2.exception java.net.MalformedURLException is never thrown in body of corresponding try statement
catch (MalformedURLException e){}
This is the part of my code in which errors occur
try {
InetAddress inet = InetAddress.getByName("www.davidreilly.com");
System.out.println ("IP : " + inet.getHostAddress());
catch (MalformedURLException e){}Please help me to correct and why unreported exception java.net.UnknownHostException; must be caught or declared to be thrown if I dont use try and catch statements
Thanks in advance.why unreported exception java.net.UnknownHostException must be caught or declared to be thrownBecause it's a rule of Java.
if I dont use try and catch statementsBut you do 'use try and catch statements'. There's one of each in your code.
You're just catching the wrong exception. Nothing in your code throws MalformedURLException yet you have a catch block for it, and InetAddress.getByName() throws UnknownHostException and you don't have a catch block for it.
You also have an empty catch block, which is very poor practice. At least print something out in the catch block ... -
Iam trying to figure out how to quicken the processing of InetAddress.
It takes abt 8 seconds to determine that there is no hostname corresponding to input ip and below 1 second for an ip which has hostname. All I want is just wait for 2 seconds in the non-existing case. Can this be achieved using a seperate timer thread, if so how?I'm bored, so why not...
public class InetAddressFetcher extends Thread {
private String name;
private InetAddress address;
public InetAddressFetcher(String name) {
this.name = name;
public InetAddress getAddress() {
return address;
public void run() {
address = InetAddress.getByName(name);
// Convenience method
public static InetAddress fetch(String name, int timeout) throws UnknownHostException {
InetAddressFetcher fetcher = new InetAddressFetcher(name);
fetcher.start();
// Wait to see if it finishes. If it does, join() will return before the timeout.
try {
fetcher.join(timeout);
} catch (InterruptedException e) {
throw new UnknownHostException("Thread interrupted while looking up host " + name);
// See if it actually got something in the allocated time.
if (fetcher.getAddress() == null) {
throw new UnknownHostException("Lookup for host " + name + " timed out");
} else {
return fetcher.getAddress();
}Then you'd just call InetAddressFetcher.fetch("hostname", 2000) to use a 2 second timeout. If it times out, you get an UnknownHostException just like the normal methods would give you. -
// Demonstrate InetAddress.
import java.net.*;
public class InetAddressTest
public static void main(String args[]) throws UnknownHostException
InetAddress Address = InetAddress.getLocalHost();
System.out.println(Address);
Address = InetAddress.getByName("osborne.com");
System.out.println(Address);
InetAddress SW[] = InetAddress.getAllByName("www.nba.com");
for(int i = 0; i<SW.length; i++)
System.out.println(SW);
// I tried to run above program on my Ubuntu 10.11 in eclipse but got following errors
//The method getLocalHost() is undefined for the type InetAddress
//The method getByName(String) is undefined for the type InetAddress
//The method getAllByName(String) is undefined for the type InetAddress
//please tell me where i am wrong .I suspect you have a class of your own called InetAddress.

InetAddress.isReachable() is acting strange
I have three machines. One server running Linux, one PC inside our firewall running XP and one PC outside our firewall running XP. The PC outside our network is connected through a VPN to our network.
I have a little java application running on both XP machines that check to see if the Linux box is reachable.
import java.io.*;
import java.net.*;
public class Reachable
public static void main(String args[])
while (true)
try
InetAddress address = InetAddress.getByName("tux.xyz.com");
System.out.println("Name: " + address.getHostName());
System.out.println("Addr: " + address.getHostAddress());
System.out.println("Reach: " + address.isReachable(3000));
catch (UnknownHostException e)
System.err.println("Unable to lookup tux.xyz.com");
catch (IOException e)
System.err.println("Unable to reach tux.xyz.com");
try
Thread.sleep(1000);
catch (Exception e)
}The XP box that inside the firewall says that the Linux box IS reachable, but the XP box that is outside the firewall says that the Linux box IS NOT reachable.
We have checked our firewall and both XP boxes are getting through on port 7. The Linux box is getting the requests on port 7 also as I can see them using Ethereal.
Any ideas why InetAddress.isReachable() would be returning FALSE?
FYI, if I turn on the echo server on Linux, which uses port 7, the XP machine outside the firewall NOW says that the server is reachable...
Much thanks.
-JeffYeah, did notice that reply, but what is weird is that I am not getting a connection refused. I am not getting anything...
The Linux server is visible from both the inside XP machine and outside XP machine via ping. What I thought was weird was that the inside XP machine was able to get to the Linux box, but the only way the outside machine was able to get to the Linux box was when I turned on the Echo service on port 7. That is what is weird. So turning on the Echo service made sense, but did not at the same time... -
InetAddress.getByName failing for valid domains
On some machines, domains starting with the hyphen (and other non-alphabetic characters) are not resolved by InetAddress.getByName()
nslookup does resolve the domains, so they seem to be valid - perhaps not by the RFC, but it seems that other common tools do consider the domain to be valid.
here are some domains that fail:
----thomiiii.hi5.com
*.letsgodigital.es
*.chordie.comI found the org.xbill.DNS package that resolves these domains.
Wondering why the InetAddress class does not. I tried looking at the source, but it led me to a native implemention:
static native InetAddress getHostByNameImpl(String name, boolean preferIPv6Address) throws UnknownHostException;
but i couldn't find the source for this native implementation.
Here is a bit of code that runs the two functions together. After it hits the exception with the InetAddress function, it retries with the Address function (from the org.xbill.DNS package, which works)
import java.net.InetAddress;
import org.xbill.DNS.Address;
public class MemLimitCheck {
public static void main(String[] args) {
try {
InetAddress ia = InetAddress.getByName(args[0]);
byte[] addr = ia.getAddress();
String host = ia.getHostAddress();
System.out.println(host);
} catch (Exception e){
System.err.println(e.getMessage());
e.printStackTrace();
try {
InetAddress ia = Address.getByName(args[0]);
byte[] addr = ia.getAddress();
String host = ia.getHostAddress();
System.out.println(host);
} catch (Exception t) {
System.err.println(t.getMessage());
t.printStackTrace();

A very deliberately invalid domain name. I suspect that one needs to come to the attention of the police. In any case the intention is clearly to fail hostname checks, so you would probably be doing yourself and everybody else a favour by letting that happen. Unless perchance you are the police.
*.letsgodigital.es
*.chordie.comThese are just synonyms for letsgodigital.com and chordie.com respectively. I can't browse to either of them, although nslookup returns an IP address, same as for without the star/dot in each case.
I do wonder what this is all about.
