Does jython require the write permission on jython.jar and library modules? We are using Jython 2.1 in WebSphere Application Server version 6.1. The jython.jar is located in WebSphere/AppServer/optionalLibraries/jython directory. The user is not able to run jython script (import sys) using WebSphere wsadmin tool when the permission is set R/O (readonly) on /optionalLibraries/jython folder and subfolders. The user got the error from BSFManager: unable to load language: jython WASX7022E: Problem running command "import sys" -- exception information: com.ibm.bsf.BSFException: unable to load language: jython It works fine after changed the permission from R/O to RW. The WebSphere is installed on z/Linux in a shared-binary environment and all the binaries common to WebSphere including jython.jar (and other open source binaries such as jacl.jar) are mounted on a separate disk in a read only fashion. They are not able to run jython command (Jacl is fine) until they change the jython.jar folder to RW. We know that jython 2.1 needs to create the cachedir (write *pkc files for each jar it loads) in python.home during initialization. We have redirected python.cachedir to a writable /temp directory, so cachedir will not be created on /optionalLibraries/jython folder. However, it doesn't help and user is still seeing the same error with R/O permission. We wonder that jython needs write access to jython.jar in addition to create cachedir (*pkc files) in python.home. Another example: We import a jython library module such as javaos (jython library modules are located in python.home/Lib directory) and execute os function in wsadmin tool. We see javaos$py.class is created from python compilation at the same location of javaos.py on /optionalLibraries/jython/Lib. If we like to set jython library module folder to RX only, is there any way (option or fix) that we can redirect the compiled class file to be generated in other writable location? We like to change all WebSphere binaries to RX instead of RWX to avoid any exposure and we like to know if jython code requires to write something on jython.jar and if this is a bug in Jython 2.1. |

Unfortunately we just don't support 2.1 any longer (it's about 8 years old and even 2.2 support is pretty much over at this point). Your best bet would be to upgrade Jython, or possibly contact IBM about the issue |
