My code is compiled on OSX and it works fine(compiler version 1.6). But when I copy it to a remote ubuntu. I can not run it.
When I run
java TPCC.class
I got exception like this.(By the way TPCC.class is in default package)
Exception in thread "main" java.lang.NoClassDefFoundError: TPCC/class
Caused by: java.lang.ClassNotFoundException: TPCC.class
at java.net.URLClassLoader$1.run(URLClassLoader.java:202)

at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
at java.lang.ClassLoader.loadClass(ClassLoader.java:248)
Could not find the main class: TPCC.class. Program will exit.
And my java version on ubuntu:
java version "1.6.0_21"
Java(TM) SE Runtime Environment (build 1.6.0_21-b06)
Java HotSpot(TM) Client VM (build 17.0-b16, mixed mode, sharing)
It's also 1.6 and I think it fits the compiled binary. How can I fix this problem?
The problem is in the way you run the program. Compiled java called
ClassName.java
will be ClassName.class. You should run it like
"java ClassName"
. You shouldn't run it as
"java ClassName.class"
What happens here is this. When you run it as java ClassName.class, JVM try to look for ClassName called "class" in the package called "ClassName" that does not exist. So it will throw NoClassDefFoundError.
This is an invocation problem as the error shows: java should be used and not the filename of the class.
The error message tries to say you this by stating that "TPCC/class" is not found.
(sorry for first adding comment, used the wrong field)
Specify the classpath when invoking java:
java -cp <path-to-jar> TPCC

With or without the previous step, I added com.microsoft.z3.jar to Classpath, located at the Plugin.xml Runtime tab. In this case, the plugin is not finding the handler that is invoked after button press command.
!MESSAGE plugintest.handlers.SampleHandler cannot be found by

In fact, this approach worked for me a previous a installation (Dell, Intel, x64, Eclipse Mars (x64), Java 1.8 x64)!
Following the discussion in https://github.com/Z3Prover/z3/issues/1093, I configured Native Library Location of com.microsoft.z3.jar with the Z3 Build directory. Calling the Z3 Build from Eclipse plugin, the error reported is the same as in Approach 2, but calling it from a Java application, the error is more specific:

What is working is when you have a Java application under the Z3 build directory. Can anyone help how to use the Z3 build directory from a Java application, or from Eclipse plugin. By the way, I followed approach #2, was working fine until I try to replicate it (because my laptop crashed) and forced to use another laptop, then the same procedure is not working for me (I had luck, before). Right now, the new laptop has the following settings:

At runtime your code needs to find com.microsoft.z3.jar, libz3.dll/.so/.dylib, and libz3java.dll/.so/.dylib. Java takes care of the first one, but the operating system will have to find the other libraries, i.e., whatever environment your code runs in must be set up such that PATH (Windows), LD_LIBRARY_PATH (Linux), or DYLD_LIBRARY_PATH (OSX) point to the libraries. Also, make sure that your version of Z3 and your version of Java are both 32-bit or 64-bit, otherwise the error messages you get may not be very informative.
For some flavors of Java, it may also be necessary or helpful to provide the java.library.path setting to the JVM.
I upgraded to Java 8 from Java 6.
As per these instructions, in /Applications/IntelliJ IDEA 13 CE.app/Contents/Info.plist I changed
<key>JVMVersion</key>
<string>1.6*</string>
to
<key>JVMVersion</key>
<string>1.8*</string>
My environment variable JAVA_HOME is set to:
/Library/Java/JavaVirtualMachines/jdk1.8.0_05.jdk/Contents/Home
However, when I run the debugger in IntelliJ, it still wants to use Java 6:
/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/bin/java ...
Connected to the target VM, address: '127.0.0.1:60490', transport: 'socket'

at java.lang.ClassLoader.defineClass(ClassLoader.java:621)
What other settings do I need to change in order for IntelliJ to use the Java 8 JRE?
You changed the IDE's setting. Project setting can be changed here: File->ProjectStructure->Project SDK

I met an error when I running the sample of JProfiler7 offline on my windows PC , the code is from "jprofiler7\api\samples\offline\src\TestProgram.java" ,and got the message as thus:
JProfiler> A different instance of the native library has been
JProfiler> loaded. Please check the appropriate environment
JProfiler> variable. (PATH, LD_LIBRARY_PATH, DYLD_LIBRARY_PATH)
JProfiler> Exiting.
I'm sure there is no any JProfiler process running, and I've imported the referenced libraries by "agent.jar" and set my PATH of JProfiler：
C:\Users\user>echo %PATH%
C:\Program Files\Java\jdk1.6.0_33\bin;C:\Program Files\java\jdk1.6.0_33\jre\bin;C:\Program Files\jprofiler7\bin\windows-x64;C:\Program Files\jprofiler7\bin;
I wanna use the JProfiler API for remoting doing something ,could anybody know how to fix that?
JProfiler:7.2.3
Windows: Win7 Enterprise SP1
JDK:1.6.0_33
And if I use the arguments as following:
-agentlib:jprofilerti=offline,id=4321,config=C:\Program Files\jprofiler7\config\config.xml "-Xbootclasspath/a:C:\Program Files\jprofiler7\bin\agent.jar"
there will be another message:

I tried to run the demo of platform (jprofiler7\api\samples\platform\src-profiler\TestProfiler.java) , got the same message both without args and with args(-agentpath:C:\Program Files\jprofiler7\bin\windows\jprofilerti.dll=offline,id=112,config="C:\Program Files\jprofiler7\config\config.xml -Xbootclasspath/a:C:\Program Files\jprofiler7\bin\agent.jar):

JProfiler> loaded. Please check the appropriate environment
JProfiler> variable. (PATH, LD_LIBRARY_PATH, DYLD_LIBRARY_PATH)

solved that.
In my way, firstly, I start a Java application with VM args
"-agentpath:C:\Program Files\jprofiler7\bin\windows-x64\jprofilerti.dll=port=8849"
Then I run a JProfiler platfrom program with args :
-agentpath:C:\Program Files\jprofiler7\bin\windows\jprofilerti.dll=offline,id=112,config="C:\Program Files\jprofiler7\config\config.xml -Xbootclasspath/a:C:\Program Files\jprofiler7\bin\agent.jar
then I could catch some information , with null value.
Profiling data :
Memory data:
Exception in thread "main" java.lang.NullPointerException
at com.jprofiler.core.comm.d.a.getTotalHeapUsage(ejt:100)
at TestProfiler.dumpMemoryData(TestProfiler.java:82)
at TestProfiler.dumpProfilingData(TestProfiler.java:55)
at TestProfiler.main(TestProfiler.java:47)
In a word , it could run...so ending the question.
Replace the -agentlib VM parameter with
-agentpath:C:\Program Files\jprofiler7\bin\windows\jprofilerti.dll=offline,...
and remove the -Xbootclasspath VM parameter
I would like to run TestNG Suite from command line on Linux. I'm using eclipse to run test, but I have problem with command line. I know that I need to have testng.jar and I have it in /home/karcio/dev/testng-6.4.jar, location my suite xml is /home/karcio/git/java-test-automation/Automation/test-output/Default suite/TestSuite.xml . Commands what I tried,
set classpath /home/karcio/dev/testng-6.4.jar
cd /location to my suite xml file: java org.testing.TestNG TestSuite.xml
This is error what I see:
Exception in thread "main" java.lang.NoClassDefFoundError: org/testing/TestNG
Caused by: java.lang.ClassNotFoundException: org.testing.TestNG
I'm new in those path and classpath, I'm little bit confusing :(
Thank you
Little update,
I think I did all good, now when I put to terminal: java org.testng.TestNG Test.xml
I've got this error:
Exception in thread "main" org.testng.TestNGException: No sourcedir
was specified at org.testng.TestNG.checkConditions(TestNG.java:1170)
at org.testng.TestNG.privateMain(TestNG.java:1010) at
org.testng.TestNG.main(TestNG.java:997)
all path are exported, so maybe this is wrong version of testng.jar, tried with versions 5.5, 6.4, 6.5, 6.6, 6.7 but I think only version 5.5 is working,
There is a typo in the class package
org.testing.TestNG
should be
org.testng.TestNG
(There no i in the .testng. part)

Can anyone provide any suggestion why is it happening?
You have essentially compiled your code with JDK 1.6 but running it with Java 5 - Just ensure a Java 6 runtime.
Even I faced same problem. The problem is inappropriate class version, for ex. compiling with different jre.
Solution: IF you are using Eclipse or RAD, set change compiler setting as per your requirement and also change same setting to project configuration by clicking on "Configure Project specific setting". Windows->Preferences->Compiler-> click on link "Configure Project specific setting".
For me the fix was to set the JAVA_Home system variable to the correct path.
It is a compiler issue. Make sure all your modules are configured with java 1.5 as a compiler. Window-->preference--> Java --> Compiler. Make sure 1.5 is selected.
