Reading/writing attributes in encode/decode

In tipical scenario with two JSF pages, both working with a simple bean (user), and with navigation from page1 to page2:
Page1.jspx:
<h:inputText value="#{user.name}"/>Page2.jspx:
<h:outputText value="#{user.name}"/>I suppose that in the encodeBegin method of the InputTextRenderer class, to read the value of value attribute there should be a sentence like this:
getAttributes().get("value");But, what kind of code is needed in the decode method of InputTextRenderer class, to receive the value from the request, and update the name property of user bean, in order to display it correctly in outputText tag of page2 ??
Thanks!

[Edit] nevermind.

New Charset Encoder/Decoder for Microsoft telnet

Hello,
I have a problem for writing a server which is accessible by microsoft windows telnet.
I have managed to find out these relationships:
          switch ((int) c) {
               case -27: c = '�'; break;
               case -28: c = '�'; break;
               case -102: c = '�'; break;
               case -103: c = '�'; break;
               case -108: c = '�'; break;
               case -114: c = '�'; break;
               case -124: c = '�'; break;
               case -127: c = '�'; break;
So how could i write an encoder/decoder which could map these charcters specially and others as norma ISO-8859-1.
I switched them after encoding/decoding but then i got problem, that
i got two characters(in telnet window). First was some wierd symbol and second the right character.
Any help lplease?

Okay, got working the charset include and everything is okay.
Now i need to look after charcodes below 0. I though that it would be useful to create new charset for this purpose which adds little extra functionality to IBM850. When running this code it says that IBM850 charset not found when initilizating X-MICRO charset. But it is accessible in main program. Any ideas what is wrong?... Please help me, this damn internationallization has driven me mad.

so, my problem is I was unable to read the attribute of the tag book , that is "id".
can any one tell me how to read this "id" attribute.

[email protected]

hi,
U r retriving the elements by tag name.So it just chks the tag name ie.<book> & gives u array of elements.But u need retrive d attribute of <book> tag itself.
=Solution =====
Add one more statement ----> var[]= doc.getElementsByName("book");
Now u hav book elements as an array & can retrive id in for loop
for(var; var.length;var++)
doc.element[var].id.value

What my program do is to get the encoding of XML files and convert them to UTF-8 encoding files, while I need this "encoding" information of the original XML document thus I can convert...
After reading specifications and JDOM docs, the truth turns to be disappointed, no function is provided to get this information in JDOM level 2(the current released one), while it's promissed that this function will be provided in JDOM level API....
Thanx all for your help and attention!!!

Stax reading /writing need help from xml guru plz

hi, i have been told that stax reading /writing should involve no overhead and that is why i use it and i am now able to write my large data to file, but using my reader i seem to run out of memory, using netbeans profiler i ahve found that char[] seems to be the problem,
by backtracing i ahve found that javax.xml.parser.SAXParser.parse calls the xerces packages which eventually leads to the char[ ], now my code for my reader is attatched here...

}i thought it may have been a recursive problme, hence having so many instance variables instead of local ones but that hasn't helped.
all i need at the end of this is a Collection which holds an array of testCollections, which holds an array of cCounts and i was able to hold all of this in memory as all i am loading is what was in memory before it was written.
can someone plz help
ps when i use tail in unix to read the end of the xml file it doesnt work correctly as i cannot specify the number of lines to show, it shows all of the file as thought it is not split into lines or contains new line chars or anything, it is stored as one long stream, is this correct??
here is a snippet of the xml file:

please if anyone has any ideas from this code why a char[] would use 50% of the memory taken, and that the average age seems to show that the same one continues to grow..
thanks in advance
danny =)

hi, i am still having lo luck with reading the xml data back into memory, as i have said before, the netbeans profiler is telling me it is a char[] that is using 50% of the memory but i cannot see how a char[] is created, my code doesn't so it must be the xml code...plz help

Public Read-Only Attributes

I'm trying to pick up ABAP on my own by reading through various resources I've collected and writing my own programs. Unfortunately I don't have an experienced ABAP guru to ask questions of. I'm hoping someone can help me with the following:
Based on my other programming experience I know that it is very common for object attributes to be defined as private and then accessor/mutator (getter/setter) methods to be defined to provide access to the attribute.
In my study I noted that ABAP allows attributes to be made public but declared to be read-only. This would seem to permit a structure where accessor/getter methods are not needed (the attribute can be read externally) and one would only have to define a mutator/setter method.
My question: what is typically done in 'real-world' programs? Is there any reason why using read-only would be more or less preferred?
Thanks for any help that can be provided.

Hello Tony
Below I have listed a few examples from standard ABAP classes. I cannot say whether you find more public read-only attributes than GETTER methods - you will find examples for both of them.
I could imagine that before it was possible to use the functional method call in ABAP that public read-only attributes were an alternative to the "verbose" method cal (see below)l.
" RE-FX: Contract
CL_RECN_CONTRACT-IF_RECN_CONTRACT~MS_DETAIL   " public read-only attribute
" MM: Material
CL_IBASE_R3_MATERIAL->GET_MARA " GETTER method
"FI/CO: Company Code
CL_REEXC_COMPANY_CODE=>GET_DETAIL " GETTER method
" HR: Employee
CL_PT_EMPLOYEE->IF_PT_EMPLOYEE~PERNR   " public read-only attribute
" Assumption: CL_IBASE_R3_MATERIAL would have
" a public read-only attribute MS_DETAIL (of TYPE mara)
" Normal method call (verbose):
CALL METHOD go_material->GET_MARA
RECEIVING
    R_MARA = ls_mara.
" Functional method call:
ls_mara = go_material->get_mara( ).
" Accessing public attribute
ls_mara = go_material->ms_detail.

Issue: Characters / encode /decode & Solution

Hey guys,
Few issues on this, I think we will need an encode/decode filter.
I guess this is related to how if you read a cookie in liquid it converts characters like a comma into its entity (This isn not fixed yet).
Example:
<meta property="og:description" content="{{description | strip_html | truncate:200,'...' }}">
The resulting markup is:
<meta property="og:description" content="Seven advisers within National Australia Bank's (NAB) salaried advice business, NAB Financial Planning (NAB FP), have transitioned to the bank’s newly-launched self-employed model.
As first ...">
You can see it has stripped out the html markup but has encoded a ' with it's entity. I can see in some cases this is good but in other cases this is bad. You can also see that <br/> while stripped are treated as new lines instead.
Liquid itself for these reasons have:
escape - escape a string
escape_once - returns an escaped version of html without affecting existing escaped entities
strip_html - strip html from string
strip_newlines - strip all newlines (\n) from string
newline_to_br - replace each newline (\n) with html break
You only have strip_html but not the other filters. I think if you implemented these then we can address these issues.

Hi Liam,
The encoding problem cannot be reproduced. Even in your example, some of the quotes are outputted correctly while a single one not. Can you edit the source of the content and try to re-enter the character from the editor, just to eliminate a possible copy / paste issue from word with a weird character encoding?
On the new line issue, it seems to happen on some scenarios. For example:
{{" <div>Seven advisers within National Australia Bank's (NAB) salaried advice business, NAB Financial Planning (NAB FP), have transitioned to the bank's newly-launched's self-employed <br /> model. at first's</div>" | strip_html }} - does not reproduce the problem
<meta property="og:description" content="{{" <div>Seven advisers within National Australia Bank's (NAB) salaried advice business, NAB Financial Planning (NAB FP), have transitioned to the bank's newly-launched's self-employed <br /> model. at first's</div>" | strip_html }}”> - does reproduce the problem

ASN.1 encoder/decoder

Hi All,
I have a asn.1 definition file.
I need to encode/decode the a file with the help of the above definition file. I tried using JavaAsn1Compiler, this compiler fullfill all my requirments except the one GraphicString type is not supported in this compilier.
Can any body suggest me a asn.1 encoder/decoder.
Thanks in advance.

We already used nokalva for OSS file parsing. From now onwards we dont want to use third party tools, is there any hand written code avialable for parsing an ASN.1 file using java.What part of my last reply did you not understand?
The java API does not contain anything for ASN.
Everything outside of the Java API would be consider third party.
So either explain exactly what it is that you want without using the term "third party" or recognize that what you are asking does not exist.

Invalid Session ID - cookie encode/decode

Hello,
I'm looking for the correct combination of cookie encode/decode parameters for my own setup.
Machine am : AM Server 7.0 on WS6.1
Machine amc : my own webapps using AM client SDK & protected by a Policy agent. 2.2 Everything within a WS6.1 container.
After being redirected to AM, I obtain my iPlanetDirectoryPro cookie and my webapp can obtain a SSOToken using the SSOToken token = manager.createSSOToken(String) if obtain the String via Cookie accessor's method.
No luck with SSOToken token = manager.createSSOToken(HttpServletRequest) which always gives a Invalid Session Id message. I know that this is an encoding problem but I tried many combinations & heard that these settings are not always well documented. I have at the moment :
am server AMConfig.properties :
com.iplanet.am.cookie.encode=false
am client sdk AMConfig.properties :
com.iplanet.am.cookie.encode=false
policy agent AMAgent.properties :
com.sun.identity.agents.config.sso.decode = false
com.iplanet.am.cookie.encode = false
Has somebody worked that out ?
Thanks !

Efficiency of reading/writing files character-by-character

I've been assuming that when I do a file "open for access," that among the housekeeping functions set up behind the scenes, there is some sort of buffer created, the size of which is somehow related to the logical sector size of the disc in question, so that reading or writing short pieces of text, or even single characters, doesn't cause independent physical read/write actions at the disc drive.
Does anyone know if this is true or false? Maybe the question would be clearer posed another way. Suppose I set up a loop to read or write 1024 characters, sequentially, but one at a time. Obviously the loop will require much more time to execute than a singe read or write statement calling for 1K of text all at once. But will there be significantly more activity at the disc drive itself? Will the data be read or written on 1024 successive spins of the platter, or will it be buffered down to one spin, or maybe a couple, depending on the exact location of sector boundaries and so on?
Thanks.

Thanks for this. I was sure some such facility was in operation, but I couldn't find anything explicit on the question. I have a task in which I'm trying to convert what looks like incredibly badly formed XML application files into properly tagged and well-formed XML so that I can then get them through a well-designed XML parser. To decode these utter shambles requires decision logic that goes nearly character-by-character. One tutorial page I found on Applescript file I/O suggested that reading/writing character-by-character was inherently inefficient, which I can see that it is, I just wanted to make sure the inefficiency didn't go all the way down to the mechanics of kicking the disc for every single character. The description in the tutorial was ambiguous, and a little disconcerting.
The tutorial also suggested an alternative strategy of reading an entire file at once into a string and then working with the string. But my files are megabytes long, and I wonder how efficient operations are on megabyte strings, presuming there isn't a limit on string length. Short of trying to do some complex adaptive algorithm, which I might never get working right, I'm pretty sure that keeping to the KISS principal, and just going character-by-character, is a near-optimal strategy in my case.
Cheers.

Sample java code which reads xml attributes using DOM Parser

Hi Friends,
I am looking for a sample java code which uses the DOM Parser to read the attributes values.
My xml looks like below
<?xml version='1.0' encoding='UTF-8'?>
<root>
<header unid="100" status="true">
<validation stage="1" processed="10"/>
</header>
</root>
Experts please help...
Thanks in Advance

You have probably found lots of resources on the www for this by now, if not: [http://www.w3schools.com/dom/default.asp|http://www.w3schools.com/dom/default.asp]

Simple and very fast encoder-decoder

I will explain my need with an example;
www.domain.com/photo.jsp?id=23
here id is 23 and people can try every photo by incresing or decreasing the id number. I want to encode the id's while printing the id to screen as url and will decode everytime when i get the request from user.
So i need a very fast and simple logic of encode & decode. I have tested base64 at java but everyone knows the algortihm. Is there any other simple algorithm that i can generate on my own?
What do you advice to me except changing my database and search with hex keys?

believe me its strictly
needed on a photo web site... there are too much
reasons.I can't think of one.1)when ids are sequantial on db users can get the idea which after or before this photo is uploaded
2)when you see the normal integer numbers on ids you can remember it easily and edit the link by hand and see whats going on...
3)When u see user_id is=1 u can understand easily that he is an admin or one of the first member of website
4)when u try the maximum photo id or user id every user can understand how many user or photos are there in website
there are lots of things like above... They may be not that valueble for everyone but i think this have to be.

Basic Text Encoder/Decoder help

Hi. I'm trying to make a Encoder/Decoder for a program to make the gamesaves safer, since they are in a .dat file and can be changed in Notepad. I was wondering if the Text can be Encoded (like a=l, b=m, ect) and decoded using a simple code before the UTF is written.

Ok, now I have a bit of a problem. I am trying to at least read the hash using readByte(), but the hashes are different. This is the code I'm using:
public void Load() //Load Script
     { try
               md5Actor_2 = MessageDigest.getInstance("MD5","SUN");
               md5Actor_1 = MessageDigest.getInstance("MD5","SUN");
               md5_1 = md5Actor_1.digest(hash_1.getBytes());
               md5_2 = md5Actor_2.digest(hash_2.getBytes());
          catch (NoSuchProviderException e1)
               System.out.println(e1);
          catch (NoSuchAlgorithmException e2)
               System.out.println(e2);
          //catch (UnsupportedEncodingException e3)
          //     System.out.println(e3);
          load = new FileDialog(dialog, "Load Game v1.1", FileDialog.LOAD);
          load.show();
          file_name = load.getFile();
          f = new File(file_name);
          long modified = f.lastModified();
          if(debug)
               System.out.println("Last modified:");
               System.out.println(modified);
          if (f != null)
          { if (file_name != null)
               { try
                         FileInputStream fis = new FileInputStream(file_name);
                         DataInputStream dis = new DataInputStream(fis);
                         level = dis.readUTF(); //level
                         cur_HP = dis.readUTF(); //cur_HP
                         max_HP = dis.readUTF(); //max_HP
                         atk_str = dis.readUTF(); //atk_str
                         def_str = dis.readUTF(); //def_str
                         cur_exp = dis.readUTF(); //cur_exp
                         exp_ned = dis.readUTF(); //exp_ned
                         loc_x = dis.readUTF(); //loc_x
                         loc_y = dis.readUTF(); //loc_y
                         temp_md5_1[1] = dis.readByte();
                         temp_md5_2[1] = dis.readByte();
                         System.out.println(md5_1+"     "+temp_md5_1);
                         System.out.println(md5_2+"     "+temp_md5_2);
                         if (temp_md5_2 != md5_2)
                              System.out.println("File Cannot be Loaded. Please Create a new GameSave");
                              success = false;
                         else
                              System.out.println("File Loaded Sucessfully: " + file_name);
                              success = true;
                         if(success)
                         { if (temp_md5_1 != md5_1)
                                   System.out.println("The GameSave is out of date. Saving the game will update "+file_name+"'s GameSave Version");
                         fis.close();
                    catch (Exception e)
                         System.out.println("There was an Error Loading the File: " + file_name);
                         System.out.println(e);
               if (success)
                    stats_txf.setText("Lvl: "+level+" Health: "+ cur_HP +"/"+ max_HP+"   Exp: "+cur_exp+"/"+exp_ned);
                    loaded = true;
                    setTitle(title+": "+ file_name);
     }Now, I may be reading the file wrong. I know the hash has a length of 16, but if I try to read 16 bytes, I get an EOFException. And, if it's possible, I would like to know how to read an Byte[ ], and not just a Byte.

Audio/Video encode & decoding

I am very new to mac environment,
and have a background as a linux developer. I worked mostly with avcodec and avformat api's (from ffmpeg project) to manipulate media. I could reach media devices/streams using oss, alsa, v4l or v4l2 interfaces/drivers and encode/decode them with avcodec API. Now I switched to mac and I want to get audio/video frames from input devices and encode/decode them as I want. I already took a look at QTkit and QT related topics but there is no codec variation and also no control of frames which has taken from input device/file. There is no flexibilty with almost just one way to encode media (h264 and AAC, with predefined bitrates). I am using snow leopard with Xcode 4 so AVfoundations is avaliable just for IOS env. and not for Mac environment.
I can not find any detailed media encoding/decoding document or usable(flexible) framework in mac developer central. Please help me to find or give me some advice about mac environment.
Thanks in advance .

First of all thank you xnav. But I already searched for AVFoundations and related sample sources. I do not want to change my operating system and I do not want to believe that MacOS has not got a framework embracing the media related functions at all before Lion. As I mentioned in the text above I am using snow leopard.
By the way I want to reach full control over media streams/frames and codec parameters. I want to be able to decode media stream/frame if it is encoded (for example: a web cam streaming jpeg captures using hw codec) I want to decode and resize it, maybe view it in a frame and encode it again and store it in a file or directly stream over rtsp. Is it possible ? Does't Apple have such a framework which I can find in open source environment easily (for example: ffmpeg - avcodec - avformat - avdevice). Device/driver level tools and codecs can be inside different frameworks but there must be some tools for it.
