Properties object help

Hi,
I have a properties object which has two keys. Those keys values are properties objects.
I need to put all those values into a hashtable...is there any good way of rolling through a properties object to get the values of other properties?
Thanks
Craig

A Properties object is a Hashtable. So if you have a method that takes a Hashtable, just give it the Properties object directly.
If you want to copy the values, there is a propertyNames() method that returns an Enumeration.

Help explain Properties object

Hi,
can someone explain properties objects, or link me to a tutorial? I wanna understand what to do with one when i get it, etc....
i mean if i get a properties object, should i put it into another data structure (enumeration , hashtable?)??
thanks.

How do I get the object help text into my document (report)?

I want to display the object help text (the "description" field in the object properties in the universe) in my report, but I can not find any function for that? Anyone who knows? BO version is 5.1.

All information about the classes and objects in a universe are stored in the repository database (universe domain). To get that information in your report you need to create a query on the repository database.
For an overview of all objectnames and descriptions that would be:
SELECT WA_UNV_OBJECT.OBJ_NAME, WA_OBJECT_HELP.OBJ_DATAVALUEFROM (WA_UNV_OBJECT RIGHT OUTER JOIN WA_OBJECT_HELP ON (WA_OBJECT_HELP.OBJECT_ID=WA_UNV_OBJECT.OBJECT_ID AND WA_OBJECT_HELP.UNIVERSE_ID=WA_UNV_OBJECT.UNIVERSE_ID) )
Note: this if from BO6.5 using SQL server 2000 for the repository database.

Problem loading PipedInputStream in Properties object

Hi there!
Well, I'm having some problems trying to load a PipedInputStream into a Properties object.
First of all I read a file with FileInputStream and BufferReader and every time I find a special token it's opened a new Thread to save this piece of the whole file into a PipedInputStream/PipedOutputStream. The thing is once I have the PipedInputStream I want to load this stream into a Properties object (Properites.load(PipedInputStream pis))
I mean....
I have a file like this
OBJECT = CLIENT
NAME = JOE
EMAIL = [email protected]
END OBJECT = CLIENT
END
OBJECT = CLIENT
NAME = ANGELINA
EMAIL = [email protected]
END OBJECT = CLIENT
END
and I want to save each CLIENT OBJECT into a Properties object. That's why every time I find the token "END" I open a new Thread and write to an PipedOutPutStream. The problem is that once the PipedInputStream is available I try to load it into the Properties but it doesn't load anything at all.I dont get any Exception, when I debug, after loading the PipedInputStream the Properties object still remain void but when I echo the stream to the console It works fine so it might not be a problem of the PipedInputStream but of Propreties.load()
Thanks for your help!!!!!

Comment out these lines of code and see what happens:// Making sure that the PipedInputStream
// has some content inside
    String line = null;
    BufferedReader read = new BufferedReader(new InputStreamReader(_pin));
    while((line=read.readLine()) != null){
        System.out.println(line);
    }Streams tend to be readable only once and by using the reader you have read through to the end of the stream so that there is nothing left for the properties object to read. Some streams will support 'mark' so that you can 'rewind' but you're not using that here.

Properties object from GET

I don't know which MQ component is requesting these three files. Are they intended for public use?
com/sun/messaging/Destination_defaults.properties
" Destination_types.properties
" Destination_labels.properties
Most importantly, how does one build a Properties object from a file fetched with GET??
Thanks.

Some classes look for certain property files for defaults
and if they are not there, then some built in hard coded
defaults are used instead.
I'm not sure what 'features' you are adding to the mqapplet
demo but any MQ developer (ie programmers at large) do
not need to dissect imq.jar in the manner you appear to be
doing - unless I am misunderstanding what you are trying to
do.
MQ developers only need to include the jar files that we
distribute as part of the product in CLASSPATH (the docs should
point out which ones are relevant). The various files inside these
jars and their dependencies should not be a concern of the
MQ developer. For example, the fact that various defaults/labels
are kept in some .properties files in imq.jar is something that
you don't need to know or care about to make your application
work.
hope this helps,

Persisting a properties object across the whole of my program.

Hello all,
As per usual, sorry for any idiocy on my part and thanks for any guidance.
I have written a wrapper class for the Properties class.
I have an MDI which creates a properties object and loads it at start up, and I have tried to use the same object again (to save any property changes) when the app terminates. However, I get a nullPointerException when I try and use it when the program closes. Below is what I hope are the relevant pieces of code. I don't include it all as it a couple of hundred lines long - but can easily do so if you think it will help. Many thanks once again:
Here is the load properties method:
private void yLoadProperties(){
        String workingDirectory = System.getProperty("user.dir");
        File yFile = new File(workingDirectory + "\\KTProperties.ini");
        YPorperties yProperties = new YPorperties(yFile);
        yProperties.yLoadProperties();
        // Retrieve application name - no conversion required
        yApplicationName = yProperties.yGetProperty("ApplicationName");
}and here is the exit program method with the call the the save properties method
private void yExitApplication(){
        // Save properties back to disk
        yProperties.ySaveProperties();
        // Exit
        System.exit(0);
    }I have also declared the yProperties variable thus:
private YPorperties yProperties;
I was hoping to use the yProperties object anywhere within my program to adjust properties as required. Any help, gratefully received.
Steve

That's just the way Java works. I'm sure someone is able to quote chapter and verse of the Java Language Specification that spells it out, but the basic distinction is this:
A variable declaration has the form: <Type> <variableName> [= <value expression>];.
A variable assignment (which assigns a value to an existing variable) has the form: <variableName> = <value expression>;
When you specify the type of a variable, Java assumes you are declaring a new variable in the current scope, regardless of whether the name of the variable already existing in a enveloping scope. When you don't specify the type, Java will look for an existing variable with that name in the current scope and any enveloping scopes.
In my mind, when I explicitly declared yProperties, thus:> private YPorperties yProperties;> I was making it available to the whole program.With that line you declared a member variable of type YPorperties (shouldn't that be YProperties, by the way?), which means a separate yProperties variable is available as a member of each instance of your class. Note that you already specify the type of the variable yProperties in that line, so there is no need to specify that type again when using the variable further on in your application.
But yes, you are correct in saying that this variable would be available anywhere inside that one instance of your class. However, it is possible in Java to declare a variable with the same name in a different, narrower scope (as you have seen).
Java looks for variables from the narrowest scope outward, so in this case it sees the local variable yProperties before it sees the member variable yProperties.
(BTW for future reference, note that a class or an instance of a class is not a "program" as such. So declaring a private member variable does not make it available to your "program", it makes it available to an instance of a class. The fact that you use that class to start your application is irrelevant)

Custom component - how to store java Properties object in ucm environment

Hi Experts,
I am developing a custom component.
my custom component code is reading a properties file and load in Properties object. Everytime this custom Service is called, properties file is read from file system and new Properties Object is created.
Is there any way to load the Properties object once and store somewhere in UCM context ? (just like we do in JSP using application object"
thanks!!
Edited by: user4884609 on Jul 12, 2010 3:01 PM

I'd say there are quite a few ways how to do it, but many of them have nothing in common with UCM.
- I'd opt for the only "UCM" way I' aware of: as a part of custom component you can create your own properties file (it's also called environment variables) as a part of your custom component. You can, then, easily read (and write?) properties from/to the file.
- The first option could have disadvantage, if there are too many properties. In this case you could use Java serialization - it should be UCM independent
- Another option is to create your properties in the database - it is a bit similar to the first option, but it's more robust. Plus, you may use features of the database if you want to have some additional logic in you properties.
- Note that you can also create a static object, which could be initialized e.g during class load

The two property files need further process and filter out some values. The two configuration files come from different application. I want to use java.util.logging.LogManager.readConfigure(InputStream).For the last time, you've made it clear how you want to solve some as-of-yet undescribed problem. What you haven't made clear is what problem you're trying to solve. From the class you mention, it sounds like you want to read in two logging configurations (since that's what a LogManager is for) from separate applications and "filter out some values". Those are mysterious requirements at best, and if you're intending to use LogManager to process some arbitrary properties files, you're headed down the wrong path entirely. There are [much better solutions readily available|http://commons.apache.org/configuration/].

How to save a properties object to a file / how to create a properties file

hi,
i am writing an application in which all the database and user information is stored in a properties object and is later retreived from it when a database connection or login etc is required.
i wanna know how can i save this object / write it to a file i.e. how do i create a properties file.
so that every time the application is run to create a new dbase etc the entire info regarding that will be stored in a new property file.

Load:
Properties p = new Properties();
FileInputStream in = new FileInputStream("db.properties");
p.load(p);
String username = p.getProperty("username");
String password = p.getProperty("password");
// ...Save:
String username = "user";
String password = "pw";
Properties p = new Properties();
p.setProperty("username", username);
p.setProperty("password", password);
FileOutputStream out = new FileOutputStream("db.properties");
p.store(out, null); // null or a String header as second argumentThe file will look something like
username=user
password=pw

Adobe Bridge CS6 undefined in not an object Help Please

I am so sick and tired of getting this error message when I try to create a pdf contact sheet - undefined is not an object. Can someone help me?
What frustrates me the is there is no log file telling me what image has the problem which Bridge does not like.
This example is of brand new eps files that were created in the last month
I also have the same undefined object is not an object using AI files but none are shown in this example.
If there is no solution to tell me what eps or ai file(s) bridge does not like - is there a setting I can change so Bridge skips the file it does not like? Sorta silly skipping a file for a contact sheet but if that is a workaround to make it bridge work that would be a huge improvement versus the program not working at all, LOL...
1. I have tried using another program to rename all my files to be sequential numbers too, so that is taking more time and I am losing the ability to find my files by name and I still get the undefined is not an object.
2. I am to the point of using other programs to create jpeg images of AI and EPS files and then using bridge to make contact sheets and doing that takes a ton more time and is just silly to do so now I am to the point of asking for help.
3. Operating system is Wondows 7 - I use CS6 - Adobe Bridge for making contact sheets - screen shoot is attached - all CS6 items are up to date with updates.
4. Yes, I have searched the internet for help and searched adobe for help --- seems like no one has posted a solution.

I am having this same issue. I'm attempting to make a pdf in Bridge but am getting the error message "undefined is not an object." A log or a report of some kind would be very useful here to find out which object is the offender. Looking at my files they appear to be in order but obviously something is amiss....

/* The encryption begins */
byte[] textBytesEncrypted = ciph.doFinal(textBytes);
String text= new String(textBytesEncrypted);
pw.write(text);
in.close();
pw.close();
Any help would be greatly appreciated.

You have not really supplied enough code to say exactly what is wrong BUT I would bet it is because you are treating files as containing chars and lines instead of just bytes.
My suggestion - read the input files as bytes and encrypt/decrypt using CipherInputStream.

You define vertexFanObj in a for loop. then try to access it from outside that for loop. (in another for loop)

myLL2[ i] = new LinkedList();
vertexFanObj = new vertexFan(); //I MOVED THIS LINE

Hi,
The error message means that the BPDU class doesn't have an empty constructor. You must pass the in needed arguments to the BPDU constuctor.

Array of cfc object help

I just picked up coldfusion about a month ago, so my
coldfusion lingo sucks. I have been programming in C++ for over 5
years now and will be using a lot of C++ terminology to help avoid
any confusion. I am writing a cfc function that preforms web
servicing. This function needs to return an object/class that is
defined in another coldfusion function. I can do this without a
problem if I only need to return one instance of this object.
However, I cannot seem to return an array of this object (I need to
return multiple instances of this object, kind of like a query, but
for programming purposes it needs to stay as an object).
It seems that the webservicing function hates my return type.
If I try to make an array of the object, it does not like array or
the object as the return type. However, when I take this function
out of the cfc, and make it a cfm, it gets the array of objects
just fine. So, I think I am having issues with the return type on
the <cffunction> tag. So I came up with the idea of creating
another object which will hold an array of the first object and
using the second object as the return type. Here is some psuedo
code of the function I am working on:
<cffunction name="SelectGames" access="remote"
returntype="ArrayOfGames" output="false">


<cfobject component = "myArray" name>
<cfobject component="games" name="test">
<cfset counter = 0>
<cfloop query="getevents">
<cfset counter = counter + 1>
<cfset test.Game_id = event_id>
<cfset test.gameDate = eventdate>
<cfset test.Starttime = starttime>
<cfset test.Place = place>
<cfset test.Level = level>
<cfset test.Sport = sport>
<cfset test.Gender = division>
<cfset test.Opponent = opponent_id>
<cfset test.Type = type>
<cfset test.Link = spec_name>
<cfset myArray.gamesArray[counter] = test>
</cfloop>
<cfreturn myArray>
</cffunction>
It keeps telling me that it does not recognize the return
type.
Here are examples of the two objects I am using from the 2
dif. cfc files:
<cfcomponent>
<cfproperty name="gamesArray" type="array">
</cfcomponent>
<cfcomponent>
<cfproperty name="Game_id" type="numeric">
<cfproperty name="gameDate" type="date">
<cfproperty name="Starttime" type="string">
<cfproperty name="Place" type="string">
<cfproperty name="Level" type="string">
<cfproperty name="Sport" type="string">
<cfproperty name="Gender" type="string">
<cfproperty name="Opponent" type="string">
<cfproperty name="Type" type="string">
<cfproperty name="Link" type="string">
</cfcomponent>
Feel free to post any questions to clear anything up, I know
this is confusing and I probably did a poor job of explaining my
problem. Also, if I throw this code into a cfm and try to make an
array of games, it works, this is the code I got it to work with:
<cfset myArray = newArray(1)>
<cfloop query="getevents">
<cfset counter = counter + 1>
<cfset test.Game_id = event_id>
<cfset test.gameDate = eventdate>
<cfset test.Starttime = starttime>
<cfset test.Place = place>
<cfset test.Level = level>
<cfset test.Sport = sport>
<cfset test.Gender = division>
<cfset test.Opponent = opponent_id>
<cfset test.Type = type>
<cfset test.Link = spec_name>
<cfset myArray[counter] = test>
</cfloop>
I guess my problem is I do not know how to specify a type for
an array.

The return type of this FUNCTION would be returnType="array".
No matter
what kind of data the array contained.
That's what I get for fast proofing.

ColdFusion is typeless,
