Java class doesn't load correctly under windows
by Josef Meile 24 Aug '04

24 Aug '04

Hi, I'm trying to programatically load a java class file to a folder on the Zope DB called 'JMFiles' during the initialization of a Product called JMColorPicker. It works under linux, but on windows 2000 the applet isn't showed and I got an error on the java console which says: Error loading class: ColorPicker java.lang.ClassFormatError Then I tried to manually load the applet class file on the ZMI and it worked. Printing the filesystem path reveals that it is correctly separated with "\". But, some how, manage_addFile corrupts the file on Windows. The code is attached to the message. Does somebody knows what the error could be? Thanks in advanced, Josef __doc__="""Misc utilities""" __version__ ='$Revision: 0.1 $'[11:-2] #File: Misc.py located on Products/JMUtils DATA_BASE_PATH='/JMFiles' def _createFileInFolder(context, filePath, fileName, zopePath, title=''): """Creates a the folder <zopePath> and puts the file <filePath>/<fileName> on it """ pathLen=len(zopePath) #Remove leading slash if (zopePath[-1]=='/') and (pathLen>1): zopePath=zopePath[0:pathLen-1] if zopePath[0]!='/': #The product will only work with relative paths #if the instances can adquire them. log('The path "%s" is relative.' %zopePath, severity=WARNING,detail='For better results use absolute paths.', product='createFileInFolder') zopePath='/'+zopePath pathParts=os.path.split(zopePath) basePath=pathParts[0] folder=pathParts[1] #This only happens when no slash is given at #the beginning of the path, so the root will #be assumed fileContainer=context.unrestrictedTraverse(basePath,None) if fileContainer==None: log('The path "%s" doesn\'t exist on the Zope DB.' %basePath, severity=PROBLEM,detail='Create it first.', product='createFileInFolder') return fileFolder=fileContainer #If the given path wasn't the zope root if folder!='': try: manage_addFolder(fileContainer,folder,'JMFiles') except: #The Folder already exists pass fileFolder=getattr(fileContainer,folder) absolutePath=os.path.join(filePath,fileName) data=file(absolutePath) try: manage_addFile(fileFolder,fileName,file=data, title=title) except: #The file was already created on a previous session pass I called it on the __init__.py of my Product: __doc__="""JMColorPicker initialization module.""" __version__ ='$Revision: 0.1 $'[11:-2] #File __init__.py located on Products/JMColorPicker from JMColorPicker import JMColorPicker, manage_addJMColorPickerForm, \ manage_addJMColorPicker from Products.JMUtils import Misc import Globals, os PRODUCT_HOME=Globals.package_home(globals()) def initialize(context): try: context.registerClass(JMColorPicker, constructors=( manage_addJMColorPickerForm, manage_addJMColorPicker, ), icon='images/icon.gif', ) context.registerHelp() #The applet is under "PRODUCT_HOME/java" absolutePath=os.path.join(PRODUCT_HOME,'java') appContext=context._ProductContext__app Misc._createFileInFolder(appContext,absolutePath,'ColorPicker.class', Misc.DATA_BASE_PATH,title='ColorPicker Applet') except: from sys import exc_info, stderr from traceback import format_exception from string import join type,val,tb=exc_info() stderr.write(join(format_exception(type, val, tb),'')) del type,val,tb

Developement and Production Site synchronization
by Jerome R. Westrick 23 Aug '04

23 Aug '04

Yo zopistas... How do you all manage your code? The Zope versioning thingy is not good! If got a backup site, I need to keep in sync was thinking of using it as developement, and then releaseing to production by tar /opt/zope and untaring into the zope directory... Is this a good Idea? Are there better ways? any Ideas will be gratefully read! Jerry

IOError: [Errno 9] Bad file descriptor
by Erik Myllymaki 23 Aug '04

23 Aug '04

I have an external method that uses reportlab to make The method takes one argument, a Databse key, does a lookup of the database record for that key and then makes a PDF file using reportlab and writes it to the local HD of the zope server. The method works well outside of Zope, but called from Zope, it only works every second time (exactly). The first call will work, but the second will fail with: Error Type: IOError Error Value: [Errno 9] Bad file descriptor then the third call work work, etc. - any ideas? - Zope 2.7.0 on windows 2000 Server.

Debugging Script (Python) - where is the traceback?
by Dave Kuhlman 23 Aug '04

23 Aug '04

I'm embarrassed to ask such a simple question, but I've done searches and I've looked through the Zope Book and the Zope Wiki, but still cannot find this. I have a Script (Python). When I call it from DTML, I get the following: Error Type: RuntimeError Error Value: Script (Python) get_size has errors. Where does Zope write the traceback to? I have "debug-mode on" in my etc/zope.conf, but that does not seem to make a difference. Or does it, and I just do not know where to look? Thanks for help.
