couldn't run the TestProgram of JProfiler offline sample - api

Question

all
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):

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.

Answer 1

Replace the -agentlib VM parameter with
-agentpath:C:\Program Files\jprofiler7\bin\windows\jprofilerti.dll=offline,...
and remove the -Xbootclasspath VM parameter
