Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Download jperf
2. Read README: "run the following script : jperf.bat"

What is the expected output? What do you see instead?
Jperf should execute, however does not.

What version of the product are you using? On what operating system?
Jperf 2.0.2

Please provide any additional information below.
Jperf will run without issue if the jperf.bat file is edited (without
quotes) to look like this:
"start javaw -classpath
jperf.jar;forms-1.1.0.jar;jcommon-1.0.10.jar;jfreechart-1.0.6.jar;swingx-0.9.6.j
ar
net.nlanr.jperf.JPerf
exit"

I don't know that this is so much of a defect than it is a configuration issue 
that
should be known for Win users.

Downloaded JPref 2.0.2 for windows and jpref.bat is set as per the 
recommendation w/o
double quotes and in singe line except for 'exit'. Every time it says could not 
find
the main class and the program exits.

uploaded is my jpref.bat

Thanks,

csvenkata,

From looking at your batch file, there appears to be a couple of issues.

First you reference "jpref" in your batch file instead of "jperf".  You may 
want to 
change that and attempt again.  Also,  you still need to ensure that java is 
correctly set up within System Variables.

I have attached my jperf.bat for your reference as well.  Note that as I dont 
devlare with

Sorry about that...

As I was saying, I don't declare within the batch file directly to C:\ as I 
have 
these set up as system variables.  Also, to note in this configuration, I have 
jperf 
located in c:\jPerf\.

Let me know if you need more assistance with this.

I still receive error "Could not find main class".  I tried all variations as 
stated 
above.  I even use the C:\jperf directory.

I also have tried all the recommendations here, but still receiving the same 
error .."Could not find the main class. Program will exit!"

Any ideas?

Was trying it on my work desktop and wasn't working, so I tried it on a couple
laptops we have lying around and they worked fine.
Thought it might have been my desktops java so I've updated that still to no 
avail.

The batch file needs javaw.exe to be in the current Windows path.  Mine wasn't 
(on Win 
7).  So I found the latest javaw.exe on my system and modified the batch file 
as 
attached.  It worked!

You may have done what I did - used a windows utility like winzip to unzip the 
archive and did NOT select the "Use folder names" option.

To add some adaptability I re-wrote the script like this:

----- jperf.bat -----
@ECHO OFF
SETLOCAL ENABLEDELAYEDEXPANSION
SET Count=0
SET java_classpath=
ECHO java_classpath='%java_classpath%'
FOR /r . %%a IN (*.jar) DO (
  IF !Count! EQU 0 (
    SET java_classpath=%%a
  ) ELSE (
    SET java_classpath=!java_classpath!;%%a
  )
  SET /a Count+=1
)

@ECHO ON
START javaw -classpath "%java_classpath%" net.nlanr.jperf.JPerf

@ECHO OFF
SET Count=
SET java_classpath=
----- end jperf.bat -----

This assumes that javaw is in the Windows %PATH% environment variable.

Comment #10's bat file, just find your javaw on your system and edit his bat 
file. Replace the current path with yours. (Mine was C:\Program Files 
(x86)\Java\jre7\bin)

I copied the installation files to the JAVA directory and ran the batch file 
from there!

My Win7 JAVA directory -->  C:\Program Files (x86)\Java\jre1.6.0_05\bin

On Windows 8 solution 10 worked. Just change the path "Path=C:\Program Files 
(x86)\Java\jre7\bin;%Path%" to jre7 to accommodate the latest version of Java.
