Re: [Snippet] Creating on-demand PDF using iText

[Helge Staedtler]

I wrap these JAR's usually in a very primitive Framework.
i just create a folder which ends with ".framework" and some dirs inside of
it like this path shows and then throw the .jar inside of it.

 MyNameForThisFramework.framework/Resources/Java/iText.jar

and put the whole stuff into

 /Library/Frameworks/


I then add the Framework to my app as i do with all other frameworks. this
way I also know what to deliver for deployment. is this a valid solution,
too?

regards,
helge

Thanks for the example!

I would recommend /Library/WebObjects/Extensions as being generally  
a safer place for third party jars used with WebObjects.  Putting  
them in /Library/Java/Extensions can lead to class loader "issues"

Thx! Lesson learned and just moved the JAR!

Neither the online copy of the 5.2 or 5.3 docs, nor indeed my local

you've changed the order of the sentence.


You have:
1) Command line args
4) ~/WebObjects.properties
2) Application Properties file
3) Framework Properties file

however, the online doc states:
The application properties can come from four sources: the command  
line, the application's Properties file, the Properties files of any  
frameworks the application includes, and the file  
WebObjects.properties in the user's home directory.


Which is:
1) Command line args
2) Application Properties file
3) Framework Properties file
4) ~/WebObjects.properties

So how are the former conclusions being made? Has someone actually  
tested this?

Creating PDF output on demand

[Stefan Pantke]

I need to compose PDF output based on certain input,

- partly based on XML   
... and apply styles for PDF output
- partly based on images and Text
... and apply 'simple' composition rules for PDF output

I know of FOP, but just found iText

http://www.lowagie.com/iText/

iText seems to be well documented and feature rich. At least for my
second task, this might be a good solution to further evaluate options.

My PDFs need to be high-resolution to be printed on high-resolution
imaging/printing machine.

But: Do we have a PDF lib, which especially integrates well with WO?

Description: application/applefile







  com.webobjects.foundation 
	
	Class NSProperties 


	This class extends Java's properties
	mechanism to merges various
	properties from the application properties with the standard system
	properties so that they are all
	available using the java.lang.System.getProperties
	method. The application properties can come from four
	sources: argument parameters from
	the command line, the file
	WebObjects.properties in the user's home
	directory the application's Properties file,
	and the Properties
	files of any frameworks the application includes, in that order of precedence.and the file
	WebObjects.properties in the user's home
	directory


	This class has only static methods and cannot be instantiated.
	
This class would have benefitted from
inheriting key-value-coding for 'getProperty'.
The Properties File 

	The application and any
	framework can include a file named Properties in its
	Resources. The Properties file must be in the format
	specified by java.io.Properties.


	Boolean values, NSArrays, and NSDictionaries must be specified using
	the property list representation. See the
	NSPropertyListSerialization class description for more information
	on property lists.

Command Line Properties 

	The
	setPropertiesFromArgv method parses the cFor command line arguments
	and recognizes
	to be recognized as
	properties, they must fit the property formats listed
	in the table below.


	
		
			Format
		
		
		
		
			Example
		
	
	
		
			-Dkey=value
		
		
			 
		
		
			-DWOPort=4321
		
	
	
		
			-key value
		
		
			 
		
		
			-WOAutoOpenInBrowser NO
		
	


	Properties specified in
	these formats will be available as System properties after you
	invoke setPropertiesFromArgv.


Accessing the Properties 

To access the application
properties you first need to merge the application and command line
properties with the System properties. AThe application properties are
automatically merged with the System properties when a
WebObjects application starts
up. automatically
performs this step for you. You can then access the property
as a string, and convert the string to the property's actual data
type.


	To obtain the application
	properties and merge them with the System properties you have to
	invoke setPropertiesFromArgv.


	Every property is a key-value pair. For example, on Mac OS X, the property value for the key
	"java.vendor" is "Apple Computer, Inc.". To access a
	property corresponding to a particular key, use the
	java.lang.System.getProperty method. This method which returns the property as a string.


	If the property string represents a value other than
	java.lang.String, for example, "TRUE" for a boolean value, the String value, "("San Francisco", "New York",
	"Seoul", "London", "Seattle", "Shanghai")" for an NSArray, or
	the String value, "{ user = wshakesp; birth
	= 1564; death = 1616; }" for an NSDictionary, you can convert
	it to the appropriate data type using the
	NSPropertyListSerialization's booleanForString,
	arrayForString, or dictionaryForString
	method, respectively. NSPropertyListSerialization also provides an
	intForString method to simplify converting a property
	string to an integer.


More on the representation of non-String properties as strings can
be found in the document: "Property List Programming Guide for Cocoa".

TCPMonitor shows initial wsdl lookup but not invoke calls

[Cara MacNish]

Hi, I have a basic web service example working and am trying to use  
TCPMonitor to view the SOAP messages for the method invocations. With  
the help of a googled websphere document (the apple doc only gives  
instuctions for using it with D2WS and makes no sense otherwise) I  
worked out how it works. Its now catching messages that appear to  
contain the whole wsdl spec of all the methods and data types, but I  
cannot get it to catch an invoke call - ie the SOAP package of an  
actual method invocation - despite the fact that the methods are  
working fine.


The only conjecture I can think of is that, while I point the client  
to the TCPMonitor listen port, when it first looks up the wsdl, it  
passes through the TCPMonitor (the message I get) but that then  
rather than using the port I've pointed it to (the listen port) for  
subsequent requests, it gets the port published in the wsdl and uses  
that for all subsequent requests, thus bypassing the monitor. Does  
that make sense? If so, then I could get around this if I edited the  
wsdl, but I assume this only exists "in the server's memory" as I  
can't find any file for it.


Am I missing something?

Cheers
Cara

Re: what are the limitations of the JNDIAdapter?

[Benjamin J Doherty]

Friends,

I've pushed ahead with the JNDIAdapter and settled on a paradigm of  
mapping LDAP-style objects to Java-style objects. Some problems and  
questions still remain, especially with respect to relationships  
between JNDI objects and anything that involves reading or writing  
the relativeDistinguishedName attribute.


However, I believe I'm closer to my goal of being able to use  
auxiliary classes. Here's my method:


I created a set of base classes for every objectClass in the schemas  
on my LDAP server all in a single EOModel. The base of my searches is  
just the nameless root (""), so I also have needed to create  
additional EOModels for any functional instance of my EOF classes.  
All the base classes are functionally abstract in that they're never  
instantiated in my application, but I'm not declaring them abstract.  
What's important here is that I've implemented inheritance from Top  
down for each class. So almost every class has a parent. (A few  
auxiliary classes don't even inherit from Top.) I also start creating  
custom business logic for these classes, so for example inetOrgPerson  
has some special methods that automatically generate a cn attribute  
to be used in the relativeDistinguishedName, etc. Here's the  
description of my generic inetOrgPerson class:


className = "org.mygroup.directory.InetOrgPerson";
name = inetOrgPerson;
parent = OrganizationalPerson;

Then I create another EOModel for parts of the LDAP tree where I'm  
going to actually be creating entries. I named them after their RDN,  
but that's not important. Here my concrete instances of classes are  
just copied and pasted from the base model:


className = "org.mygroup.directory.Staff"; name = Staff;

It's important to know that org.mygroup.directory.Staff inherits from  
org.mygroup.directory.InetOrgPerson. I copied the inetOrgPerson  
entity from my base classes and pasted that into the new EOModel with  
a new name. You can't give the new class a parent, because EOF  
considers the two classes to be in separate "databases," so it can't  
do a deep fetch, so it complains and dies.


For me, all my Staff are inetOrgPerson-classed and posixAccount- 
classed. Because posixAccount is auxiliary, I've interpreted that as  
an interface. I got EOGenerator to give me a _posixAccount class  
which I modified into an interface named posixAccount. Now I can  
paste the grubby details from the _posixAccount class into my classes  
which implement the posixAccount interface. There's really nothing  
magical going on here. It's just a cheap and easy way to always get  
good methods for my interface by pasting the generated ones into my  
superclass.


This allows me to edit existing entries in the LDAP database. I can  
edit all the attributes for my Staff records, not just those from  
either inetOrgPerson or posixAccount classes.


How do I create records with both objectClasses inetOrgPerson and  
posixAccount? This is speculative now, and I will report more later.  
If you've got cautionary tales, please tell me so I don't repeat your  
mistakes. I've discovered that I can make the objectClass property in  
EOF visible to the server side. It's type also needs to be NSArray  
instead of String. What I can say is that THIS DOES NOT CAUSE MY APP  
TO CRASH. Yay! But now EOF won't generate the objectClass  
automatically, so I need to create it myself in the business logic.


What have I learned so far?

1.  When confronted with multiple inheritance, choose the parent  
class that will bring in the most custom logic.
2.  Just like in LDAP, you should build around structural classes.  
Map auxiliary LDAP classes onto java interfaces.
3.  It's not harmful to cast multi-valued LDAP attributes as NSArray,  
but then you need to deal with some special situations. I believe  
Chuck Hill posted some code about dealing with multi-valued  
attributes on the list a few years ago, and that's useful. Basically  
you need classes to handle actual multi-valued attributes and those  
multi-valued attributes that may only hold a single value in a  
particular instance and so EOF hands off a String instead of a NSArray.


What am I gonna do now? I must write a method which checks for the  
existence of the appropriate object classes (somewhere around  
awakeFromInsert probably) and sets them if necessary. If that works,  
I'll use inheritance to my advantage and make all superclasses  
provide their type.


If that doesn't work, I'm going to have to create some structural  
subclasses that inherit from multiple places. So MyorgStaff would  
inherit from inetOrgPerson and posixAccount. Not elegant but it will  
work.


Cheers,

Benjamin in Chicago

Re: Finding out client IP.

[Tanmoy Roy]

Hi Gennady,
Please find below a code piece that we use for getting the client IP.

public String getIpFromWOContext (WOContext iContext) {
String  aUserIP = null;

if (iContext != null) {
if (iContext.request() != null )
aUserIP = iContext.request().headerForKey("remote_addr");
}
return aUserIP;
}

Thanks,
Tanmoy

You have backtracked too far problem

[Peteris Krisjanis]

I have app, which stays on Main WOComponent all the time. I use  
WOConditionals to show additional partial WOComponents which are made  
to be 'plugged in' in page. I have one such big partial WOComponent  
which holds many small partial WOComponents. I activate it when user  
log ins (with WOConditional). However, after that when try to click  
on links which are binded to actions to turn on another WOConditional  
and show another partial WOComponent. These links where created in  
the begining


Before I put in big WO custom object, other partial WOComponents with  
WOConditionals showed up perfectly. But _now_ (with that big one  
active) when I click on link, I get "You have backtracked too far"  
message. As far as I debuged, links to actions seems to be 'too old'.  
How to create so they would fefreshed each time I change page this way?


How to deal with such situation?

Peter.

Re: Java Bridge for beginners

[Helge Staedtler]

Hi Alexandr,

there is some interesting example at www.wocode.com

http://WOCode.com/cgi-bin/WebObjects/WOCode.woa/wa/ShareCodeItem?itemId=430

which makes use of the objective-c classes/frameworks from apple through
native access via java. i tried it personally an also played a little with
the code to manipulate it in the one or the other direction. perhaps it
might be a starting point for you.

regards,
helge

p.s.: why do you cross-post this question to so many lists? people clicking
on "Anser to all..." won't have in every case rights to post to the other
lists. my response goes to the webobjects-dev-list only.

Java Bridge for beginners

[Alexander Kholodovitch]

Hello, All!
Excuse, who can help me? I write on Java. But I should cause the classes 
written on Objective-C (Objective-C++). Tried to read about Java Bridge. But 
could understand not all. Some materials have become outdated. For example, 
about Java Wrapper.


Somebody can send the reference to a simple example of use Objective-C of 
classes from Java (the best variant - source codes of the project)? Or on 
step-by-step instructions, for achievement of similar result.

Re: WOSession and setStoresIDsInCookies method

[Helge Staedtler]

I always use the simple way of wrapping a frame around the application which
loads the webobjects-urls inside of it.
this way users always have a valid url to bookmark. only in apps with
direct-actions as default-startup-situation I leave away the frame.

you can also popup a modal window via javascript, that way people do not see
any url at all AND whats even better they do not have any backbutton any
more. ;-)

using rewrites you can shorten the url cutting down the base-url i think,
but you will still have the "number.number.number" following the base-url
because thats how webobjects stores the state.

if there does exist something to eliminate even this part of the url through
cookies and rewrites I would be interested in it, too.

regards,
helge

WOSession and setStoresIDsInCookies method

[Peteris Krisjanis]

I want to store session and instance IDs in cookies, so I add two  
methods in my Session.java:


setStoresIDsInCookies(true);
setStoresIDsInURLs(false);

And I can browse my app without seeing rather large session ID.  And  
for example, my URL

looks like that:
http://dev-peteris.local:59359/cgi-bin/WebObjects/johaidi_server.woa/ 
wo/0.20.0


However, when I clean up url and go to
http://dev-peteris.local:59359/cgi-bin/WebObjects/ 
johaidi_server.woa/, session seems to be vanished.


What I should do that session id is left stored in cookies and I can  
still manipulate with URL?


Also is there any useful references (posts, emails) for "hiding"  
WebObjects url and creating good one? How url_rewrite works

with WebObjects sessions, etc?

Already thanks for any answers,
Peter.
