import os query

[nick3216 ()]

I have some Grinder 3.1 scripts which will be running on Windows XP2/CentOS 5 machines so I need to be able to normalise path names. I have the following directory structure on all machines, where on the XP machines '/' is equivalent to 'C:\'

/
|
+-Testdata
   |
   +-Certificates

I would normally normalise path names like this:

import os
...
    keystore = os.path.normpath("/TestData/Certificates/" + certificateName)
    grinder.SSLControl.setKeyStoreFile(keystore, certificatePassword, "pkcs12")

But in The Grinder that gives the following error:

14/05/09 16:57:09 (thread 0 run 0): Aborted run due to Jython exception: ImportError: no module named javaos [calling TestRunner]

In the error logs the error occurs at the line number where I invoke os.path.normpath I've looked in the jython.jar file which is in the Grinder lib directory and the os.class is there as part of org.python.modules. So I tried:

from org.python.modules import os 

which gives the same error, at the same point. Trying

import javaos

gives the same error but at the line where I do the import. Is there a way of importing either the os or javaos module which doesn't involve me installing Jython?

[Calum Fitzgerald]

have you tried doing a full install of jython?

or maybe try:

from os import path

keystore = path.normpath("/TestData/Certificates/" + certificateName)

That gives exactly the same javaos error:

javaos [calling TestRunner]

As the os.class is included in the jython.jar that comes with The Grinder I don't understand why I should need to do a Jython install when the class is already there in the lib directory.

If I include jython.jar in my classpath I can see it being processed when the agent starts, and annoyingly the path is being normalised by The Grinder. I say annoying because obviously The Grinder can do what I'm trying to do:

grinder.properties:

grinder.jvm.classpath = /grinder-3.1/lib/jython.jar

XP Console output when agent starts - jython.jar processed and path to it is normalised:

*sys-package-mgr*: processing new jar, 'C:\grinder-3.1\lib\jython.jar'

I was also trying to avoid installing Jython as I have a batch of machines acting as injectors and as well as updating them all I'd have to work around the differences between CentOS5 and Windows XP jython installations. Also at some point I might need to run my scripts from the Amazon EC2 and I don't want to have to bother about the configuration of the load injectors there.

Is there a way of importing the os.class in the jython.jar in The Grinder lib directory?

Alternatively as The Grinder is a java app is there no simple way of importing javaos? This would provide me with the same functionality.

[Calum Fitzgerald]

if there is a java class that provides what you need you can import
that and use it within Jython:

maybe:
java.io.File
or
java.net.URI

java.net.URI has a normalize method
(http://java.sun.com/j2se/1.5.0/docs/api/java/net/URI.html#normalize())

eg:

from java.net import URI

certificate = URI(/TestData/Certificates/" + certificateName)
certificate = certificate.normalize()

On the jython classes I always tend to do a full install of jython,
and I was able to get os.path.normpath working fine...which is not a
lot of help.

That normalizes URI's so keeps forward slashes as forward slashes

[Calum Fitzgerald]

I'm not sure why you are having trouble with importing the python os
class in the jython.jar

you should be able to import javaos java classes very simply. is it
part of the core java classes? if not just drop the jar into the
classpath and you should be able to import away.

There is no javaos module in Java - in fact having just checked it's deprecated by Sun. I don't see why if I could find a jar file for it I'd have any more success accessing the classes inside it than I do trying to import from jython.jar which I can see includes the class I'm after.

No neither am I. If I include jython.jar in my classpath I'd expect to be able to access the os class within it thusly:

from org.python.modules import os 

However this doesn't work:

19/05/09 14:44:06 (thread 0 run 0): Aborted run due to Jython exception: ImportError: no module named 
javaos [calling TestRunner]

Which is where we came in...

[Philip Aston-3]

1. Install a full version of Jython.
2. Use grinder.jvm.arguments to set the Python home appropriately. E.g.

  java -Dgrinder.jvm.arguments=-Dpython.home=/opt/jython/jython2.2.1/
net.grinder.Grinder

(can also be done in grinder.properties)

I have the SAME problem. Does anyone solve it ???
