Consecutive log prints - only the first printed (no visible error)

I have this code fragment in my java class:
catch (AuthenticationFailedException afe) {
IlientConf.logger.error("[" + accountID + "," + emailConf.getIncomingUser() + "#" + emailConf.getIncomingMailServer() + "] " + "E-Mail " + protocol + encStr + " login failed on " + emailConf.getIncomingUser() + "#" + emailConf.getIncomingMailServer());
IlientConf.logger.error("[" + accountID + "," + emailConf.getIncomingUser() + "#" + emailConf.getIncomingMailServer() + "] " + afe.getMessage());
IlientConf.logger.debug("Email integration AuthenticationFailedException", afe);
return false;
}
IlientConf.logger is a log4j logger.
The actual log that is printed contains only the first line. This is it:
[someuser,sapunlock#someuser.com#outlook.office365.com] E-Mail pop3
(SSL) login failed on sapunlock#someuser.com#outlook.office365.com
The second and the third log statements are lost somehow.
I really need the stack trace of the error, but I can't get it.
No other related error is shown in the log.
Please help me understand what the reason for this is.
P.S.: Of course I can change the log statements to show this better, but this is deployed at a customers environment and needs to be solved before the next version.

How to set the multiple attributes of objectClass for UnboundID & OpenLDAP via Java 7

I'm not sure how to properly pass the multiple attributes needed for an OpenLDAP insert via UnboundID. I have omitted the objectClass attributes & received a "no objectClass" error. I have also tried comma-separated & the bracket/array route like below & received the "value #0 invalid per syntax" error.
String[] ldifLines = {"dn: ou=users,dc=sub,dc=domain,dc=com", "cn: " + uid, "userPassword: " + pw, "description: user", "uidNumber: " + lclDT, "gidNumber: 504", "uid: " + uid, "homeDirectory: " + File.separator + "home" + File.separator + this.getStrippedUser(), "objectClass: {posixAccount, top}"};
LDAPResult ldapResult = lclLC.add(new AddRequest(ldifLines));
So, the question is, how do I successfully pass these objectClass attributes in the string array included above? Again, I have tried: "objectClass: top, posixAccount" as well. Thanks in advance!

It uses an LDIF representation, so if an attribute has multiple values, then the attribute appears multiple times. Like:
String[] ldifLines =
{
"dn: ou=users,dc=sub,dc=domain,dc=com",
"objectClass: top",
"objectClass: posixAccount"
"cn: " + uid,
"userPassword: " + pw,
"description: user",
"uidNumber: " + lclDT,
"gidNumber: 504",
"uid: " + uid,
"homeDirectory: " + File.separator + "home" +
File.separator + this.getStrippedUser(),
};
LDAPResult ldapResult = lclLC.add(new AddRequest(ldifLines));
Also, the LDAP SDK allows you to use a shortcut and just do it in a single call without the need to create the array or the AddRequest object, like:
LDAPResult ldapResult = lclLC.add(
"dn: ou=users,dc=sub,dc=domain,dc=com",
"objectClass: top",
"objectClass: posixAccount"
"cn: " + uid,
"userPassword: " + pw,
"description: user",
"uidNumber: " + lclDT,
"gidNumber: 504",
"uid: " + uid,
"homeDirectory: " + File.separator + "home" +
File.separator + this.getStrippedUser());

`rtserver-id` turns to `rtserver - id` in java string

I have this code:
public void foo (){
String script =
"var aLocation = {};" +
"var aOffer = {};" +
"var aAdData = " +
"{ " +
"location: aLocation, " +
"offer: aOffer " +
" };" +
"var aClientEnv = " +
" { " +
" sessionid: \"\", " +
" cookie: \"\", " +
" rtserver-id: 1, " +
" lon: 34.847, " +
" lat: 32.123, " +
" venue: \"\", " +
" venue_context: \"\", " +
" source: \"\"," + // One of the following (string) values: ADS_PIN_INFO,
// ADS_0SPEED_INFO, ADS_LINE_SEARCH_INFO,
// ADS_ARROW_NEARBY_INFO, ADS_CATEGORY_AUTOCOMPLETE_INFO,
// ADS_HISTORY_LIST_INFO
// (this field is also called "channel")
" locale: \"\"" + // ISO639-1 language code (2-5 characters), supported formats:
" };" +
"W.setOffer(aAdData, aClientEnv);";
javascriptExecutor.executeScript(script);
}
I have two q:
when I debug and copy script value I see a member rtserver - id instead of rtserver-id
how can it be? the code throws an exception because of this.
Even if i remove this rtserver-id member (and there is not exception thrown)
I evaluate aLocation in this browser console and get "variable not defined". How can this be?

rtserver-id isn't a valid identifier - so if you want it as a field/property name, you need to quote it. You can see this in a Chrome Javascript console, with no need for any Java involved:
> var aClientEnv = { sessionId: "", rtserver-id: 1 };
Uncaught SyntaxError: Unexpected token -
> var aClientEnv = { sessionId: "", "rtserver-id": 1 };
undefined
> aClientEnv
Object {sessionId: "", rtserver-id: 1}
Basically I don't think anything's adding spaces - you've just got an invalid script. You can easily add the quotes in your Java code:
" \"rtserver-id\": 1, " +

Is Runtime.getRuntime().Exec() environment diffrent from cmd env?

I tried to run a jar from my code with the runtime command.The jar connects to another host through RMI.It throughs an exception and exits.
But when I open the jar from cmd it works fine.
The jar gets 5 arguments.
Code :
String runCommand = "java -jar WhiteboardStudent.jar "
+ "192.168.0.3" + " "
+ "2000" + " "
+ "2001" + " "
+ "test" + " 0" ;
final Process proc = Runtime
.getRuntime()
.exec(runCommand,null,new File("util/"));
Command Prompt :
java -jar WhiteboardStudent.jar 192.168.0.3 2000 2001 test 0
The code where the exception is thrown is here :
Object proxy = registry.lookup("RWD");
Whiteboard whiteboard = (Whiteboard)proxy;
I'm just stumped.any ideas?
The function that throws the exception :
Registry registry = LocateRegistry.getRegistry(
hostname, Integer.parseInt(whiteboardPort)
);
String serviceName = "RemoteWhiteboard" + sessionID;
Object proxy = registry.lookup(serviceName);
Whiteboard whiteboard = (Whiteboard)proxy;
int userid = whiteboard.userRegistry(userName, "");
Main mainFrame = new Main(sessions, sessionID,
whiteboard,userid,"");

My suggestion is try the absolute path in your code:
String runCommand = "java -jar /c/users/xxx/WhiteboardStudent.jar "
+ "192.168.0.3" + " "
+ "2000" + " "
+ "2001" + " "
+ "test" + " 0" ;

Java vs. Net HTTP Client Performance

We call a webservice from our C# app which takes about 300ms using WCF (BasicHttpBinding). We noticed that the same SOAP call does only take about 30ms when sending it from SOAP UI.
Now we also implemented a test accessing the webservice via a basic WebClient in order to make sure that the DeSer-part of the WCf is not the reason for this additional delay. When using the WebClient class the call takes about 300ms as well.
Any ideas on why Java compared to C# is about 10x faster in this regard? Is there some kind of tweaking possible on the .NET side of things?
private void Button_Click(object sender, RoutedEventArgs e)
{
executeTest(() =>
{
var resultObj = client.getNextSeqNr(new WcfClient()
{
domain = "?",
hostname = "?",
ipaddress = "?",
loginVersion = "?",
processId = "?",
program = "?",
userId = "?",
userIdPw = "?",
userName = "?"
}, "?", "?");
});
}
private void Button_Click_1(object sender, RoutedEventArgs e)
{
WebClient webClient = new WebClient();
executeTest(()=>
{
webClient.Proxy = null;
webClient.CachePolicy = new System.Net.Cache.RequestCachePolicy(System.Net.Cache.RequestCacheLevel.NoCacheNoStore);
webClient.Headers.Add("Content-Type", "application/xml");
webClient.Encoding = Encoding.UTF8;
var data = "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:ser=\"SomeNamespace\">" +
" <soapenv:Header/>" +
" <soapenv:Body>" +
" <ser:getNextSeqNr>" +
" <!--Optional:-->" +

" </ser:getNextSeqNr>" +
" </soapenv:Body>" +
"</soapenv:Envelope>";
string result = webClient.UploadString("http://server:8080/service", "POST", data);
});
}
Am I missing something here? Any idea would be helpful... ;-)
Kind regards,
Sebastian

I just found the reason for this.
It's the 100-Expect Continue HTTP Header and the corresponding implementation in .NET. The .NET client wait 350ms as default on the server. This causes the delays. Java seems to have other default values here...
Just add the following line of code very early in your code:
System.Net.ServicePointManager.Expect100Continue = false;
Cheers!
