[Zope] Structured Text Question
Is there any way to have multiple lines of empty space between two sections of text in a Structured Text document? I looked on Google but did not find any answers to this question. However, I did notice that others had asked the question as well. Is this a shortcoming of Structured Text? Any help would be appreciated.

Re: [Zope] Re: Java vs Zope
Well, the class is simply a construct that Java uses to define an object. Also, the concept of object is well defined in Java which makes it easier for the programmer to know what can and cannot be done. In Python, it is not as explicit. Java is a programming language and hence cannot be compared directly to a scripting language such as Python or PHP. These 2 types are designed for different purposes. - Asad On Fri, 6 Jan 2006, bruno desthuilliers wrote: Rocky Burt wrote: David H wrote: Python is also object oriented. In python, x = 10 creates an object not a simple type - if I recall the same is true in Java. In fact this is not quite right. In java, int x = 10 produces a primitive type.

Java does have an Integer class but that is generally only used when an object is absolutely required (which is not often). Java 1.5 did introduce autoboxing on primitive types so that int's and Integer instances could be interchanged without knowing in method calls, etc ... but x is still not an object with methods. In fact I'd go as far as to say that Python seems *more* object-oriented than Java. s/seems/is/ Java is more class-oriented than object-oriented. It forces you to use classes for everything, but not everything is an object.

Re: [Zope] Re: Java vs Zope
Actually, that's not true. Languages such as Perl and Python were designed to write scripts, not to code entire applications. Python is an exception because it can be successfully used to code large applications, unlike some other scripting languages. So it's best to call Python a scripting programming language because it has this dual nature. All said and done, I prefer to use Java over Python for large applications simply because it's cleaner and has mechanisms in place that support reusability of components and extensibility. Also, OO concepts such as abstraction and inheritance are well defined in Java. Also, both compiled and interpreted languages have their advantages and disadvantages. - Asad On Fri, 6 Jan 2006, Lennart Regebro wrote: On 1/6/06, Asad Habib [EMAIL PROTECTED] wrote: Well, the class is simply a construct that Java uses to define an object.

Re: [Zope] Java vs Zope
From my experience, Java development has been a lot faster when applications have middle to high level complexity. Since Java is inherently object-oriented, reusability is much easier to achieve then when using Zope. Also, Java has mature development and debugging environments and well organized API's. Zope is seriously lacking in this regard. Zope is good for building simple interfaces but any application that does data processing and requires session management should be left for Java. The closest comparison to Zope that I can think of is PHP. Again, this is just my opinion based on my own experiences. - Asad On Tue, 3 Jan 2006, Jonathan Cyr wrote: I always found the bytecode aspect of Java annoying... having to compile without the advantages in speed of a compiled language.

I think my confusion lies in the idea that not everyone uses Java (though they may talk about it). I do not see everyone using Java. In fact I see very few large or successful companies using it. Even Sun and IBM develop their core components in C/C++. GNU, Linux, MySQL ... all C/C++. Ditto Oracle. In my market, we've been able to easily outpace and perform competitors going the J2EE route, and for a lot less money. In regards to web development, the list of technologies being implemented is overwhelming. It took extensive research to find and settle down to Zope. In my research, I found it took 57 complex files to develop a simple and ugly J2EE application to display a list of cars from a database (various Ant, xml, jar, war and other files). In Zope this can be done in 2 objects, and it integrates nicely with apps like Dreamweaver, so it looks and feels nice. We often find the need to integrate with other products and when we do, either the product's manufacturer a) is interested in market share, or b) they avoid change. For companies who are into market share they often use a greatest common denominator technology such as C, Perl, or HTTP. Java does not play nicely here. Companies who avoid change usually do so because they produce large-scale or small market systems, and change is too expensive and hard. In this case Java, again, does not play nicely. In Java it seems that not only do you have to figure how to interface with others, you have to figure out how to do it in Java as well (which is not trivial). Zope and Python seem better at translating thoughts into code, and doing so with the right balance of object orientation, and scalability. Zope provides a solid framework for development and scalability, while providing mechanisms to include and deploy very custom and specific features in a standardized way. -Original Message- From: Andreas Jung [mailto:[EMAIL PROTECTED] Sent: Sunday, January 01, 2006 4:03 PM To: David Johnson; zope@zope.org Subject: Re: [Zope] Java vs Zope --On 1.

[Zope] Passing Parameters to External Methods
Hello. I am trying to use the Python version of the PHP script written by Jason Rust called 'HTML_ToPDF.php'. I have represented this script using an External Method since it uses functions, such as open, which cannot be used in Zope Python scripts for security reasons. The python code for the script consists of a class definition and so I have had to create a python function which instantiates an object of this class. However, I am having toruble passing parameters to this function which are needed by the class constructor to instantiate an object of this class. Can parameters be passed to external methods? Whenever I try to pass parameters to function 'createHtmlToPdf', Zope returns an error stating that no such function exists. Other on the hand, if I pass no parameters this call is successful but the init function fails complaining that three parameters are expected. I have provided a snippet of my code below. Any help would be greatly appreciated.

[Zope] Session Variable Error
I have a session variable called 'undergraduateProjectsDirected' that I
declare using the following syntax:

When I try to append items to this list variable, I get the following
error:
AttributeError: 'NoneType' object has no attribute 'append'
I know for a fact that this variable exists since flushing the SESSION
attribute of the REQUEST variable using dtml-var REQUEST.SESSION
yields its name and shows that it is initially empty.
I am using the following statement to append items:
dtml-call
(REQUEST.SESSION.get('undergraduateProjectsDirected')).append([student_name,
description])
The strange thing is that when I change the name of this variable to
'undergradProjectsDirected', the error does not occur anymore.
Has anyone experienced something similar? I think a variable with the same
name exists (perhaps I created one in another one of my intranet
applications) and Zope is referring to the old copy instead of the newly
created one. I tried flushing the transient object container as well but
it did not make a difference.
Any help would be greatly appreciated. Thank you.

[Zope-dev] Changing the Appearance of the Contents of a Local File System Object
Hello. I have a folder that I have created at the root level and inside this folder I have placed one Local File System object. The Local File System object contains two File objects. When I view the Local File System object by clicking on the 'View' option provided by the management interface, I can see that it contains two File objects. What I would like to do is to change the way that these File objects are displayed. Specifically, I would like to show only certain attributes that these File objects have and hide others. Right now, the following attributes are shown: type, icon, size, and last modified time(mtime). I would like to hide the size and last modified time(mtime) attributes. I want these attributes to be set but I do not want their values to show. FYI, I am using the Local File System Product. Any help would be greatly appreciated.

Does anyone know how to create a Zope Product? One example would be the Local File System Object that I am using. If you could point me to some resources that would be great.

[Zope-dev] Testing a value returned from a Zope Python Script
Hello. I am trying to test a value returned from a Python script using the following syntax: dtml-if expr=dtml-call expr=checkRowLength(fileObject_index, rowLength) == 0 /dtml-if checkRowLength is the name of the script. Apparently Zope flags me with an error saying that this is an invalid attribute tag for a dtml-if. Is there any other way of achieving this? Any help would be appreciated. -Asad __ Do you Yahoo!?

[Zope-dev] Creating a variable in a DTML method that may be modified
Hello. Does anyone know how to create a variable in a DTML method which may be updated by a Python script? I am currently using the set method of the REQUEST object to create a variable. However, creating a variable in this fashion renders it permanent. Any help would be appreciated. Thanks. -Asad __ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.

[Zope-dev] Running Python Scripts via the Management Interface
Hello. Does anyone know why the following script stalls when I run it in Zope's Management Interface using the 'Test' command? context.manage_addProperty(propertyId, propertyValue, propertyType) All it does is add a property to a folder. The script does function properly and doesn't stall when I access it from a DTML method. However, it stalls when I run it directly. Any help would be appreciated. Thanks. -Asad __ Do you Yahoo!?

[Zope-dev] Adding Properties to Folder Objects via a Zope Python Script
Hi. I was wondering whether any of you know if it is possible to create properties for Folder objects using a Zope Python script that can then be invoked from a DTML method. I know that this is possible using Zope's management interface, but this procedure is not scalable. Any input would be appreciated. Thanks. -Asad __ Do you Yahoo!? Yahoo! Mail Plus - Powerful.
