JProfiler UnsatisfiedLinkError when starting

I just downloaded and installed a trial JProfiler version from jprofiler_linux_7_0_1.sh. The strange fact is that there's no prompt for inputting license information in the installing process. But everything seems to be fine, until I try to run the profiler:

# sh ./bin/jprofiler -c

(The -c is to run jprofiler in console. I have read somewhere on Internet, but not sure that's true. Anyway, the result is still the same.)

Here's the results I get:

Exception in thread "main" java.lang.UnsatisfiedLinkError: /opt/jdk1.6.0_26/jre/lib/amd64/xawt/libmawt.so: libXext.so.6: cannot open shared object file: No such file or directory

I have come to /opt/jdk1.6.0_26/jre/lib/amd64/xawt; it does have libmawt.so, but no libXext.so.6. I tried to uninstall jprofiler and install it again, but the same error occurs.

Does anyone have a clue what's happening here?

Check that you have got libxtst in your operation system. To install it, you can do something like this: "sudo apt-get install libxtst6:

PS: You could also try to use YourKit Java Profiler with evaluation license.

You cannot run the JProfiler GUI in console mode. The argument -c is only for running the installer in console mode.

To set up profiling on a headless machine, run

bin/jpintegrate

To control a profiled process that does not have a JProfiler GUI attached ("offline profiling") run

bin/jpcontroller
