When I am running qpid-server.bat, I am getting following error:

I am not running any code. I am just starting qpid-server.bat and getting above error.
I would be really thankful if anyone would suggest me the solution.
After downloading the code from Apache "qpid-java-6.1.0", I also had errors running the broker. I found that the broker folder I was using was incorrect. I was able to run the broker by setting the system variable QPID_HOME to "C:\qpid\qpid-java-6.1.0\systests\target\qpid-broker\6.1.0" and running the "qpid-server.bat" in that location. You can then log into the broker at "http://localhost:8080" with user = admin and password = admin. I am not sure what the "systests" folder is or why the bin and lib files are here, but it works. Navigate to that folder and look at the files there. Let me know if there is a better folder I am supposed to be in. I then create a connection factory with the URL "amqp://admin:admin#clientid/?brokerlist='tcp://localhost:5672" and it works.
I have seen this problem caused by an incorrect setting of the QPID_HOME environment variable.
With a normal installation QPID_HOME needs to refer to the immediate parent of the lib directory. The batch file tries to determine QPID_HOME if it is not set, but will use its current value otherwise. Check you have not set it erroneously.

Shutdown JBossEAP6.3.0 service [2015-05-29 09:58:27]
Try to start jBoss server as administrator by pressing right mouse key, it will permit jboss to create all folders and files .
Right click the installation directory of Jboss EA (mine is C:\program files\EAP6.1, then Properties, Security tab. Given everyone permissions on this folder (all users you can see just give full control). This should then be able to create logs etc files within the required folder.
This is just a workaround though only works for local installs.
I had the same issue, it worked after running it on root, maybe you are running it without the proper rights.
I had resolved this issue by creating log directory in the
C:\jboss-eap-6.3\standalone\
it's a problem due to permissions, the solution that worked for me is that i removed the home directory of jboss wildfly from C:\programmes to C:\
Starting Wildfly/Jboss from the administrator cmd worked!!
You are most likely getting this error because you either have the log file open in a text editor or you're already running that instance of JBoss.
I got the same exception
Try changing the path from c to another destination, that solved my issue and I am able to start the server
I setup a tomcat 6 server in Eclipse pointing to a local tomcat folder:
C:\Program Files (x86)\Apache\Tomcat
I setup a debug configuration to point to that tomcat server with the following settings:
Program arguments:
start
VM arguments:
-Dcatalina.base="C:\Program Files (x86)\Apache\Tomcat" -Dcatalina.home="C:\Program Files (x86)\Apache\Tomcat"
Classpath Bootstrap Entries:
JRE System Library [jdk]
Classpath User Entries:
bootstrap - C:\Program Files (x86)\Apache\Tomcat\bin\
tools.jar - C:\Program Files (x86)\Java\jdk\lib\
When attempting to start the debug configuration (and subsequently Tomcat), I instantly get this error in the Console:

I think somewhere the JVM is trying to parse a "Program Files" related path, failing on the space, and thinks that "Files" is a parameter. But I don't even know where to look to find whatever path it's referencing! Is there an argument I can pass that will be verbose about what it's doing?
Install Tomcat into a directory that does not have spaces in its full path.

I'm following this tutorial http://stilius.net/java/java_ssl.php to create simple SSLServer and client sockets. I've created the certificate using keytool but I've a problem executing this line from the above tutorial,
"java -Djavax.net.ssl.keyStore=mySrvKeystore -Djavax.net.ssl.keyStorePassword=123456 EchoServer".
Where should I put the certificate? in project directory?
how can I pass the parameters mentioned above?
I'm doing this and getting error;

Edit:
my problem is that I never run a project from command line so I don't know how to run this line from command line;
C:\Users\abc\workspace\VirtualElectionBoothServer\bin>java -Djavax.net.ssl.keyStore=mySrvKeystore -Djavax.net.ssl.keyStorePassword=123456 BoothServer
From which directory should i run it? I've more than one .java files. which one to run? one having main()?
It looks like you don't know how to run a Java application from the command line.
I'll just assume that your BoothServer class isn't in a package. If it is, use its full name (e.g. the.package.name.BoothServer).
I'll also assume that you've compiled this within eclipse and that the resulting class file is in the bin directory. (If you are using packages, you should have your file under bin\the\package\name\BoothServer.class. Replace the directory names with the actual package names if this is the case, of course.)
javax.net.ssl.SSLException: No available certificate or key
corresponds to the SSL cipher suites which are enabled
This is the typical error that happens when the keystore can't be found (amongst other reasons).
Make sure the path you're using with -Djavax.net.ssl.keyStore= points to the actual keystore you've generated. For example, -Djavax.net.ssl.keyStore=..\mySrvKeyStore if your file is under C:\Users\abc\workspace\VirtualElectionBoothServer.
I also suspect that Eclipse might clear the content of bin every time it recompiles (not sure), so bin would not necessarily be a good place to keep that keystore file.
I'm trying to create a simple Java Agent program before I implement the real thing. I cannot get it to run. Clearly I have some sort of configuration or class path problem. No amount of looking and trying has lead to me the problem.
If I run:
java -cp ./demoAgent.jar -javaagent:./demoAgent.jar com.kingtigerbooks.demoMod.Main
I get the following error:

I'm running this on my Mac. The jar file with the agent is in the current directory. The manifest for the jar file looks like this:
Manifest-Version: 1.0
Premain-class: com.kingtigerbooks.demoAgent.Agent
Can-Redefine-Classes: true
If smells like a class path problem, but as you can see I have included the jar on the class path. Any help would be appreciated. Its a very simple project.
Problem solved. I had a bad jar file. The agent jar file did not contain the agent class. By building the correct jar file and putting the fully qualified path to the jar on in the javaagent parameter it all works.
when you run an agent, you do not add the agent jar to the normal classpath.
as a side note, you can add -verbose:class to the command line to get info about the class loading process.

[shutdown output]
I've run the app with java -verbose:class, and according to that output, org.apache.log4j.Category is loaded from the log4j JAR in my /WEB-INF/lib, just before the first exception is thrown.
Now, the Java versions on the two machines are slightly different. Both the machines have Sun's java, the Linux machine has 1.6.0_10, while the Windows machine has 1.6.0_08, or maybe 07 or 06, I can't remember the exact number right now, and don't have the machine at hand. But even though the minor versions of the Javas are slightly different, the code shouldn't break like this. Does anyone understand what's wrong here?
You must understand that a classloader can't see everything; they can only see what a parent classloader has loaded or what they have loaded themselves. So if you have two classloaders, say one for Jetty and another for your webapp, your webapp can see log4j (since the JAR is the WEB-INF/lib) but Jetty's classloader can't.
If you manage to make a class available to Jetty (for example something in the DB layer) which uses log4j but which ends up running in the context (and classloader) of Jetty, you will get an error.
To debug this, set a breakpoint in org.springframework.web.util.Log4jWebConfigurer.initLogging(). If you can, copy the source of this class into your project (don't forget to delete it afterwards) and add this line:
ClassLoader cl = Thread.currentThread().getContextClassLoader();
Have a look at the cl object in your debugger. That should give you some information who created it. My guess is that this is the classloader from Jetty.
[EDIT] Note that you get in a different mess if you have log4j in both classloaders: In this case, you will have two classes with the same name which create objects which are not assignment compatible! So make sure there is only a single instance of this jar or that instances of log4j will never be passed between the two contexts (which is usually not possible).
This seems like a classic classloader problem. It could be due to another web app being loaded first which also uses log4j but a version that is different to the one used by the app you are testing. The classloader uses the first version of the class it finds. The server class loading policy can usually be changed in the config files. Sorry I am a bit rusty on this but maybe it can point you in the correct direction.
Make sure there are no other installed apps on the web server,
Make sure the log4j being loaded is the correct version,
Make sure you don't have a log4j lurking somewhere in the classpath of the server.
HTH
You're using the same WAR on both machines? Have you checked if the WAR files are identical (no transfer errors occured)?
Some random things to consider:
(1) Check if there are any other versions of log4j floating around on the linux instance, outside of the web-app directories?
(2) Is apache commons logging being used at all? You might want to consider SLF4J instead?
(3) Did the JAR/WAR become corrupt in some way - was it FTP'ed in ASCII or Binary?
(4) Print out the classloader hierarchy in each case, just to see if there are any discrepancies?
Even though the original problem was solved for the asker, I'll point out that a common source of problems when running the same code on Windows vs Linux (or Unix) is case-sensitivity issues. Windows ignores case while Linux or Unix is case-sensitive. This has bitten me more than once.
So if you specify a jar or directory on the classpath, but it isn't the right case then it will fail on Linux but succeed on Windows. This can also be the source of FileNotFoundExceptions.
Had the same problem and found an easy solution/workaround:
In Eclipse in Preferences > Java > Installed JREs, select the JRE > Edit and Add External JARs... and browse to your log4j.jar.
The other workaround is to add log4j.jar to every launch definition in Classpath tab.
