GetLocalhost() always throws UnknownHostException
Hi,
On my computer the method InetAddress.getLocalHost() always throws an UnknownHostException (JRE: jre-1_5_0_05-windows-i586-p.exe).
I found a topic for this trouble (http://forum.java.sun.com/thread.jspa?forumID=11&threadID=495321) but it doesn't help me.
I think there is a problem in my network configuration. Can you help me?
My OS is XP service pack 2.

AucunThank you!
Just a guess, but try setting "Suffixe DNS propre � la connexion"
On my machine, I bring up the window Local Area Connection Status, then click on Properties, that brings up the Local Area Connection Properties window. Then I click on Internet Protocol (TCP/IP) in the list, then click the Properties button. That brings up the Internet Protocol (TCP/IP) Properties window; in there click Advanced button. That brings up the Advanced TCP/IP Settings window. In it click on the DNS tab. Down near the bottom is a box labeled "DNS suffix for this connection" and in it I have the suffix for my domain (berkeley.edu). I've never understood what the two boxes below are for/what they do.
This is just a stab in the dark; I have no idea if it will help.

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????

GetLocalHost throws UnknownHostException
We have a situation where #getLocalHost will intermittently throw an UnknownHostException. I've checked etc/hosts and everything is normal, additionally, the machine is not using DNS.
The exception is a little odd in that the local host name is listed twice:
Caused by: java.net.UnknownHostException: myhost: myhost
at java.net.InetAddress.getLocalHost(InetAddress.java:1191)If I look at the source, it seems that the actual exception is being thrown from #getAddressFromNameService on this line:
byte_array = nameService.lookupAllHostAddr(host);Anyone run into this? What's odd is that it is intermittent, not predictable.
R.Everyone gets annoyed at this one (especially when developing on a laptop). Here's a snippet of code I often use when testing code locally
* Best attempt to get the local hostname, with or without the existence of a DNS entry.
* @author [email protected]
* @return Short version of the local hostname.
* @throws UnknownHostException There is a problem with the DNS entry for this host and/or this JVM implementation
* does not return the standard error string.
public static String getLocalHostName() throws UnknownHostException {
try {
return (InetAddress.getLocalHost()).getHostName();
} catch ( UnknownHostException uhe ) {
String host = uhe.getMessage(); // host = "hostname: hostname"
if ( host!=null ) {
int colon = host.indexOf(':');
if ( colon>0 ) {
return host.substring(0, colon); // Dangerous, this is JVM dependant code.
throw uhe;

URLStream.readBytes always throw out of memory exception (errorID=1000)
When I try to load a file as 180MBytes by using URLStream.readBytes().
In some PCs, it's OK.
But in some PCs, there are always [out of memory] exception (errorID=1000) even such PC still had enough memory.
For example:
Total memory is 2G, current used is 1.43G, but URLStream.readBytes() still throw such exception.
For file with little size such as 30M, there isn't such problem.
Could any body give some suggestion?
Best regards,
Sourcecode is very simple like:
var myStream:URLStream;
var inputBytes: ByteArray = new ByteArray();
... do load ...

// for example first 500KBytes was read.

Is Sender File Adapter always throws error when there is no file?
Hi,
I have a simple question but can't find a straight answer to it. I have a Sender File adapter that configured to pick up file XXX* from FTP server every 1 hour. But a file can come every 2, 3, or 7 hours- no certain time.When there is no file I got "File not found " error. As we use alerts, this behaviour is not acceptable.
Does this error comes always if there is no file? Any possible way to avoid this error ?
Thanks for help.
NataliyaHi Ravi,
I can see the error in Runtime Workbench under CC monitoring. To be precise it says:
An error occurred while connecting to the FTP server '1X.1XX.XX.XX:21'. The FTP server returned the following error message: 'com.sap.aii.adapter.file.ftp.FTPEx: 552 RMS-E-FNF, file not found, ES4_SAP*'. For details, contact your FTP server vendor.
My ftp server has the following set up:
Server: xx.xxx.xx.xx
Port:21
Dataconnection:Active
Timeout:120
Connection secuirity: None
User name .... etc set up.
Connect mode: Per file transfer
Transfer mode:Text
QoS:EO
Pollinterval: 120 (for test purposes)
Processing Mode: delete
Can it be that its a ftp server generates error and sends back to XI?
Thanks,

Running Composite with test client always throws ContentTypeException

BPMAuthorizationService Object always throws up null
Hi All,
I'm trying to retrieve BPMUser using oracle worklist api. Here's a piece of my code:
try {
IWorkflowServiceClient wfSvcClient = WorkflowServiceClientFactory.getWorkflowServiceClient(WorkflowServiceClientFactory.SOAP_CLIENT);
IWorkflowContext wfCtx = wfSvcClient.getTaskQueryService().authenticate("bpeladmin", "welcome1", "jazn.com",null);
BPMAuthorizationService bpmAuthSvc = wfSvcClient.getAuthorizationService(wfCtx.getIdentityContext());
BPMUser bpmUser = bpmAuthSvc.lookupUser("bpeladmin");
} catch (Exception e) {
e.printStackTrace();
The jars/directories i have included in my project are:
bpm-infra.jar
bpm-services.jar
j2ee_1.3.01.jar
jazncore.jar
oc4jclient.jar
orabpel.jar
orabpel-common.jar
orabpel-thirdparty.jar
orasaaj.jar
soap.jar
wsclient_extended.jar
xml.jar
xmlparserv2.jar
config
schema
My problem is BPMAuthorizationService object is always null. On the other hand i have no problems retrieving tasks, updating payload or approving tasks.
Any help would be greatly appreciated.
Thanks.No offense taken. It does look a little rough.. but for what I'm doing and how I'm doing it I don't think it is going to get much cleaner.
Thanks for the reply, but I had two problems... one I wasn't thinking hashmap and was just looking at each entry.. never checked the next value for each entry...
The other problem that was causing my jsp further down the line to crash when it tried to load the so I thought nonexistent form PTEN was a naming problem.
I was putting the correct object into session and then naming it PTEN... later on I was pulling it from session looking for the name PTENForm. So when I corrected the "Form" it works correctly. -
JSObject.getWindow(applet) always throws JSException with no message.
I am looking for any possible reasons for this failure. We have an applet that runs fine in Microsoft VM on IE. As soon as we upgrade to use Java Plugin 1.4 and up, it stopped working because of the JSException being thrown when call is made to JSObject.getWindow(Applet).
MAYSCRIPT parameter is set, applet is signed. Everything compiles fine.
I also tried converting our HTML using HTMLConverter. But that didn't help.
I spent last two days trying everything suggested on this forum regarding this problem, with no success.
Does it matter where the call to getWindow is made? In our case, we pass our Applet as a constructor parameter of another Java class.
eg. in method actionPerformed() of my Applet class I have:
MyJavaScript myJs = new MyJavaScript(this);
myJs.callScript();
And MyJavaScript looks like this:
public MyJavaScript(Applet applet)
this.applet = applet;
public void callScript()
JSObject win = JSObject.getWindow(applet); // this line allways throws JSException when using Java Plugin, but works fine with MS VM.
// rest of the code....
Thanks in advance!OK, I think I know what our problem was. We overwrite our Applet's getAppletContext() method. And JSObject.getWindow(applet) calls this method internally.
If I return super.getAppletContext(), everything works fine.
Still, don't understand why it works in IE's Microsoft VM.
Thanks. -
WPF IDataErrorInfo - Validation not always throwing error
Hi,
In my project I have implemented IDataErrorInfo and ViewModelBase (from MvvmLight).
I have added validation for two properties, 'TaskNumber' and 'Address'.
The validation for TaskNumber checks if the given TaskNumber exists and if not, should throw an error.
However, the only way I can get any of the 2 properties to be validated is by first typing a
valid TaskNumber in the textbox, and it is from then that the validation works and outlines the textbox in red when invalid TaskNumbers are typed.
You can see my code here: http://1drv.ms/1Ch4n9r
Refer to JobViewModel.cs and NewJobView.xaml
ThanksThe validation will fail whenever the indexer of the IDataError interface returns something else than NULL or an empty string for the given property. In your case this means that the GetValidationError method should return a non-empty string whenever you
want to display the red border (or however your error template looks like) around the TextBox in the view:
string IDataErrorInfo.this[string propertyName]
get
return GetValidationError(propertyName);
If it the indexer returns a string when the view is initially loaded, you should see the red border.
Obviously you need to upload a complete reproducable and runnable sample of your issue if you want anyone to be able to point out any error in your specific code. Just posting some uncompilable code is not enough for anyone to be able to reproduce your issue.
Please remember to close your threads by marking helpful posts as answer and then start a new thread if you have a new question. -
Why getString always throw exception
Hello,
I got not too much experience particularly on JDBC. Is there someone could help?
I don't know why this piece code always catch exception?
if (!(rs.getString("survey_report").equals("0000-00-00")))
just so simple, I comment it, the whole jsp runs fine.
the 'survey_report' is a column retrieved from a previous SQL statement, not null. DB is MySQL, datatype is Date.
My platform is Tomcat 5.0.28 with MySQL 5.
More confusing to me is the same code run on JRun 2, no problem.
Will you have any idea on how I should fix it?
Regards, dovebcss02 wrote:
thanks for all of you the kindly help in advance.
it's embarrassed that I can catch the full error message, not sure if i've missed something.
here's my code.
catch(Exception b)
out.println("content error");
b.printStackTrace();
1) I can identify the part of code catch exception just the part I attached previously.
2) whilst the exception is caught, i can only print out "content error" but the printStackTrace().
Any further instruction on working the message out is welcome.
rgds, doveprintStackTrace() prints to STDOUT by default. You seemed to have defined your own "out" PrintStream, rather than using System, so the place where you're seeing your "content error" is not the same place that printStackTrace produces it's output, but it will produce it. Try
catch(Exception b)
out.println("content error");
b.printStackTrace(out);
}Also, if you don't even know what Exception was thrown, how do you know it was that statement you originally posted that threw the exception?
I absolutely refuse to believe that you have every rs.whatever statement wrapped in a try/catch block. And even if you do, using such general "error" messages as "content error", probably means that you have that same message in about 100 different places, which brings us back to the question about how you "know" that it was that statement that threw the exception? -

HDD: 1TB (5400rpm)
Graphics: Intel HD Graphics 4000Not sure if you have tried adding 8.8.8.8 to the DNS servers yet or if your messages app is a problem as well. for me the only fix was as follows:
Back up all data.
Triple-click anywhere in the line below on this page to select it:
~/Library/IdentityServices
Right-click or control-click the line and select
Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with an item selected. Move the selected item to the Trash. Log out or restart the computer, empty the Trash, and test.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
Basically drag the items in the identityservices folder to trash log out, log back in, empty trash, start messages or facetime!!

QAjmsSession.createReceiver(queue) Always Throws NullPointerException
I am trying to get the aqjmsdemo01 sample code to work, but I consistently get a null pointer error when it tries to get a receiver from the session.
The queue setup was as follows:
begin
DBMS_AQADM.CREATE_NP_QUEUE CACHE_INVALIDATION_QUEUE',false,'My Cache Invalidation Queue');
DBMS_AQADM.START_QUEUE('CACHE_INVALIDATION_QUEUE', TRUE, TRUE);
end;
The code (where it fails is like this:
System.out.println("Get the Queue") ;
/* Get the Queue */
/* Queue JMSMAPQ is created in aqjmsdemo02 */
queue = ((AQjmsSession)qsess).getQueue("FLT", "CACHE_INVALIDATION_QUEUE") ;
System.out.println("Create Receiver...") ;
/* Create a queue receiever */
qrecv = qsess.createReceiver(queue, "JMSCorrelationID='BLUE'") ; // <---- Fails Here
Any ideas ?I am seeing a similar behavior only with createSubscriber.
What is interesting to me is that it thinks that it is durable when the topic was created with the following:
dbms_aqadm.create_np_queue (
queue_name => 'px_jmx_lf_con_evt',
multiple_consumers => true);
Here is the stack trace.

Report Generation MS-Word always give error
Hi
I am using LV 2012 and MS Office 2010.
I am using report generation toolkit to have a customised output report.
When I specify output format as excel, I am able to get the desired result but when I specify output format as word, it always throws an error. I checked running the NI examples meant to give output in word but they all fail while the excel reports are perfect.
Please find attached an error code for one of the example Sample Report(word).vi
Please suggest the solution.
Regards,
Manbir

error_doc.JPG 20 KBWe need to see the code in order to say "Here is the error" or "Try doing it this way". It also gives us something to try, ourselves. Do you know how to make "snippets", which are .PNG "pictures" of your code that you can simply put into the message using Insert Image? We can then drag this image into a LabVIEW Block Diagram, and voilà, working code!
