Parsing a string to object attribute's
My string will be delimited by tab spaces. I need to parse the contents of the string then assign these to the attributes on an object. The solution I believe would similar to this String to Vector method:
public Vector stringParser(String inString) {
//Local variables.
int lastIndex = 0;
Vector retVector = new Vector();
int theCount = 0;
int indexOf = inString.indexOf( dConstants.DVX_CHAR_SEP );
//Keep on looping until there are no more DVX_CHAR_SEP
while( indexOf != -1 && lastIndex != indexOf ){
retVector.addElement( new String( inString.substring( lastIndex, indexOf - 1 )));
lastIndex = indexOf;
indexOf = inString.indexOf( dConstants.DVX_CHAR_SEP, lastIndex + 1 );
}//while there are DVX_CHAR_SEP's
//The last bit of string will not be DVX_CHAR_SEP terminated. Grab it now.
if( indexOf == -1 ){
//Just in case there weren't any DVX_CHAR_SEP.
indexOf = 0;
retVector.addElement( new String( inString.substring( indexOf, inString.length()) ));
return retVector;
NB. public final char DVX_CHAR_SEP = '\t';
And your question is...?
(By the way, I generally use a StringTokenizer to do exactly that.)

How to parse XML to Java object... please help really stuck
Thank you for reading this email...
If I have a **DTD** like:
<!ELEMENT person (name, age)>
<!ATTLIST person
id ID #REQUIRED
>
<!ELEMENT name ((family, given) | (given, family))>
<!ELEMENT age (#PCDATA)>
<!ELEMENT family (#PCDATA)>
<!ELEMENT given (#PCDATA)>
the **XML** like:
<person id="a1">
<name>
<family> Yoshi </family>
<given> Samurai </given>
</name>
<age> 21 </age>
</person>
**** Could you help me to write a simple parser to parse my DTD and XML to Java object, and how can I use those objects... sorry if the problem is too basic, I am a beginner and very stuck... I am very confuse with SAXParserFactory, SAXParser, ParserAdapter and DOM has its own Factory and Parser, so confuse...
Thank you for your help, YoHi, Yo,
Thank you very much for your help. And I Wish you are there...I'm. And I plan to stay - It's sunny and warm here in Honolulu and the waves are up :)
A bit more question for dear people:
In the notes, it's mainly focus on JAXB,
1. Is that mean JAXB is most popular parser for
parsing XML into Java object? With me, definitely. There are essentially 3 technologies that allow you to parse XML documents:
1) "Callbacks" (e.g. SAX in JAXP): You write a class that overrides 3 methods that will be called i) whenever the parser encounters a start tag, ii) an end tag, or iii) PCDATA. Drawback: You have to figure out where the heck in the document hierarchy you are when such a callback happens, because the same method is called on EACH start tag and similarly for the end tag and the PCDATA. You have to create the objects and put them into your own data structure - it's very tedious, but you have complete control. (Well, more or less.)
2) "Tree" (e.g. DOM in JAXP, or it's better cousin JDOM): You call a parser that in one swoop creates an entire hierarchy that corresponds to the XML document. You don't get called on each tag as with SAX, you just get the root of the resulting tree. Drawback: All the nodes in the tree have the same type! You probably want to know which tags are in the document, don't you? Well, you'll have to traverse the tree and ask each node: What tag do you represent? And what are your attributes? (You get only strings in response even though your attributes often represent numbers.) Unless you want to display the tree - that's a nice application, you can do it as a tree model for JTree -, or otherwise don't care about the individual tags, DOM is not of much help, because you have to keep track where in the tree you are while you traverse it.
3) Enter JAXB (or Castor, or ...): You give it a grammar of the XML documents you want to parse, or "unmarshall" as the fashion dictates to call it. (Actually the name isn't that bad, because "parsing" focuses on the input text while "unmarshalling" focuses on the objects you get, even though I'd reason that it should be marshalling that converts into objects and unmarshalling that converts objects to something else, and not vice versa but that's just my opinion.) The JAXB compiler creates a bunch of source files each with one (or now more) class(es) (and now interfaces) that correspond to the elements/tags of your grammar. (Now "compiler" is a true jevel of a misnomer, try to explain to students that after they run the "compiler", they still need to compile the sources the "compiler" generated with the real Java compiler!). Ok, you've got these sources compiled. Now you call one single method, unmarshall() and as a result you get the root node of the hierarchy that corresponds to the XML document. Sounds like DOM, but it's much better - the objects in the resulting tree don't have all the same type, but their type depends on the tag they represent. E.g if there is the tag <ball-game> then there will be an object of type myPackage.BallGame in your data structure. It gets better, if there is <score> inside <ball-game> and you have an object ballGame (of type BallGame) that you can simply call ballGame.getScore() and you get an object of type myPackage.Score. In other words, the child tags become properties of the parent object. Even better, the attributes become properties, too, so as far as your program is concerned there is no difference whether the property value was originally a tag or an attribute. On top of that, you can tell in your schema that the property has an int value - or another primitive type (that's like that in 1.0, in the early release you'll have to do it in the additional xjs file). So this is a very natural way to explore the data structure of the XML document. Of course there are drawbacks, but they are minor: daunting complexity and, as a consequence, very steep learning curve, documentation that leaves much to reader's phantasy - read trial and error - (the user's guide is too simplicistic and the examples too primitive, e.g. they don't even tell you how to make a schema where a tag has only attributes) and reference manual that has ~200 pages full of technicalities and you have to look with magnifying glas for the really usefull stuff, huge number of generated classes, some of which you may not need at all (and in 1.0 the number has doubled because each class has an accompanying interface), etc., etc. But overall, all that pales compared to the drastically improved efficiency of the programmer's efforts, i.e. your time. The time you'll spend learning the intricacies is well spent, you'll learn it once and then it will shorten your programming time all the time you use it. It's like C and Java, Java is order of magnitude more complex, but you'd probably never be sorry you gave up C.
Of course the above essay leaves out lots and lots of detail, but I think that it touches the most important points.
A word about JAXB 1.0 vs. Early Release (EA) version. If you have time, definitively learn 1.0, they are quite different and the main advantage is that the schema combines all the info that you had to formulate in the DTD and in the xjs file when using the EA version. I suggested EA was because you had a DTD already, but in retrospect, you better start from scratch with 1.0. The concepts in 1.0 are here to stay and once your surmounted the learning curve, you'll be glad that you don't have to switch concepts.
When parser job is done,
what kind of Java Object we will get? (String,
InputStream or ...)See above, typically it's an object whose type is defined as a class (and interface in 1.0) within the sources that JABX generates. Or it can be a String or one of the primitive types - you tell the "compiler" in the schema (xjs file in EA) what you want!
2. If we want to use JAXB, we have to contain a
XJS-file? Something like:In EA, yes. In 1.0 no - it's all in the schema.
I am very new to XML, is there any simpler way to get
around them? It has already take me 4 days to find a
simple parser which give it XML and DTD, then return
to me Java objects ... I mean if that kind of parser
exists....It'll take you probably magnitude longer that that to get really familiar with JAXB, but believe me it's worth it. You'll save countless days if not weeks once you'll start developing serious software with it. How long did it take you to learn Java and it's main APIs? You'll either invest the time learning how to use the software others have written, or you invest it writing it yourself. I'll take the former any time. But it's only my opinion...

How to parse a string in CVP 7.0(1). Is there a built-in java class, other?
Hi,
I need to parse,in CVP 7.0(1), the BAAccountNumber variable passed by the ICM dialer. Is there a built-in java class or other function that would help me do this?
Our BAAccountNumber variable looks something like this: 321|XXX12345678|1901|M. In IP IVR I use the "Get ICM Data" object to read the BAAccountNumber variable from ICM and then I use the "token index" feature to parse the variable (picture below).
Alternately, IP IVR also has a Java class that allows me to do this; the class is "java.lang.String" and the method is "public int indexOf(String,int)"
Is there something equivalent in CVP 7.0(1)?
thanksThanks again for your help. This is what I ended up doing:

The sproc should parse the string to retrieve the different ids that are concatenated in the stringbuffer and for each id retrieve a row from a table and in the end return a cursor containing the returned rows.Can anyone help me out with the parsing logic for a pipe delimited string.

Purpose of request.setAttribute(String parm1, Object parm2)
HttpServletRequest request.setAttribute(String parm1, Object parm2) vs. HttpSession session.setAttribute(String parm1, Object parm2)
hi
can anybody please explain to me what does HttpServletRequest request.setAttribute() do? and for what purpose is it used for?
i already know that HttpSession session.setAttribute(String parm1, Object parm2) is used to bind a session to a variable, so that it can be accessed throughout the servlet application.
thanx
shankha
ps: please correct me if i'm wrongshankha,
What does the API doco say?
I think it just sets a request scoped attribute... ie a request parameter.
This looks pertinant: http://www.rgagnon.com/javadetails/java-0401.html -
Access object attributes using other object JNI native method
Hi. I'm trying to change an attribute of object O1 from another object O2 without invoking a O1 method and without making the attribute as public or protected.
The only possibility that comes to my mind for doing so is writting a JNI native method
public class O1 {
static public native changeAttribute (Object O2, Object newAttributeValue) ;
that change the attribute memory reference, but all I've found about accesing attributes in JNI is about accessing the invoker attributes (in this case, O1).
�Does any one know if it's possible to do so? Thanks.I know that is not a good practice but I cannot figure out another way.
I'll try to explain the whole problem so you see the reason. I'm working with transactions, using objects as the data. An object can be opened for write by several transactions because the granularity for conflicts is not the object, is each of its attributes. As long as two transaction don't write the same attribute, they both can write. For writing, each transactions uses a private copy of the object. At committing, the actual copy of the object must be replaced by the committer one, but as far as the granularity is the object attributes, only each written attribute must be replaced (if not, only the last commit would be visible).
This attribute replace must be done by the transaction manager as far as the transactional object is provided by the client. So what i was thinking was to use JNI or some trick like that to replace the object attributes transparently to the object.
I hope the explain is clear, my english is a little asleep :-(.
How to do it with reflection? I thought that was only for method calling. Anyway, there wouldn't be problems if the attributes are private?
Thanks for answering.
EDIT: I've been able to change a public field using reflection, but not the private one
import java.lang.reflect.*;
class Caca {
public static void main(String[] args) {
Integer r = new Integer(0);
System.out.println("original: " + r.toString());
modifyWidth(r, 300);
System.out.println("modified: " + r.toString());
static void modifyWidth(Integer r, int newValue ) {
Field valueField; Class c = r.getClass();
try {
valueField = c.getField("value");
valueField.set(r, newValue);
} catch (Exception e) { System.out.println(e); }

Help regarding parsing the string
I wanted to display diffrent colored strings in the Textarea which is not possible. But from somewhere I came to know that it is possible by parsing the strings comming frm various sources and then display them with diffrent colors. can anyone help me out regarding this. The format is something like:
&x100100100This is a colored string!&n
the &x100100100 means that the text after it should use RGB value of 100,100,100. &n meant that the colors should stop and return to default.
Well... this makes the client need to parse strings and set colors etc

Parsing XML Node with href attribute
Hi,
I have the following XML that has to be parsed using JSP DOM. All fine except for one. The only problem that i have is when to parsing the Node with href attribute.
I am using the following method, and it returned with weird result
currNode.getAttributes() ====> the result is com.sun.org.apache.xerces.internal.dom.AttributeMap@111ae04
currNode.getNodeValue() ====> the result is null
currNode.TextNode ===> it returned *2*
Can anyone please let me know what did I miss here? What should I do to parse the href attribute into the jsp page?
The below is the xml.
<MovieList>
<Movie href="DarkKnight.xml">
<head>
<Title>Batman Dark Knight</Title>
<Genres>
<Genre>Action</Genre>
<Genre>Sci-Fi</Genre>
</Genres>
<Description>Movie Details here</Description>
</head>
</Movie>
</MovieList>ThanksI am not sure what "JSP DOM" is exactly. In the W3C DOM supported since SUN Java 1.4 if you have an element node and want to access an attribute value you can simply use String href = movieElement.getAttribute("href"); You might need to cast your Node to Element first e.g.Element movieElement = (Element)currNode;

Parsing a string using StringTokenizer
Hi,
I want to parse a string such as
String input = ab{cd}:"abc""de"{
and the extracted tokens should be as follows
ab
cd
"abc""de"
As a result, I used the StringTokenizer class with deilmeter {,},:
StringTokenizer tokenizer = new StringTokenizer(input,"{}:", true);
In this was, I can separate the tokens and also can get the delimeters. The problem is I don't know how to parse the string that has double quote on it. If a single quote " is taken as a delimeter then
", abc, ",", de," all of them will be taken as a separate token. My intention is to get the whole string inside the double quote as a token including the quotes on it. Moreover, if there is any escape character "", it should be also included in the token. Help please.
ThanksA bit of a "sticky tape"-solution...

How to reference the Parent view Object attribute in Child View object
Hi , I have the requirememt to generate Tree like struture to display Salary from joining date to retirement date in yearly form.I have writtent two Pl/SQL function to return parent node and child nodes(based on selected year).
1.First function --> Input paramter (employee id, retirement date , joining date) --> return parent node row with start_date and end_date
2. 2nd function --> input paarmter(employee id, startDate, end_date) --> return child node based on selected parent node i.e. start date and end date
I have created two ADF view object based on two function return
Parent Node --> select * from Table( EUPS.FN_GET_CONTR_SAL_BY_YR(employeeId,retirement Date, dateOf joining)) ;
Child Node --> select * FROM TABLE( EUPS.FN_GET_CONTR_SAL_FOR_YEAR( employeId,startDate, endDate) ) based on selected parent node.
I am giving binding variable as input for 2nd function (child node) . I don't know how to reference the binding variable value in child view from parent view.
Like I have to refernce employeId,startDate, endDate values in 2nd function from parent view object. some thing like parentNode.selectedStart_date parentNode.employeeId.
I know we can achive this writing the code in backing bean.But i want to know how can we refernce parent view object attribute values in child view object using Groovy or otherway?

Caused by: oracle.xml.parser.v2.XMLParseException: '=' missing in attribute
This is a Bursting problem under EBS 5.6.3. In production we have 5.6.2 and since our development system to 5.6.3 has been upgraded, the following error occurs on every single Burst being done using the Concurrent Manager only:

I can run the same file through 5.6.3 ($JAVA_TOP) libraries mounted on my JDev with no problems. Also the same XML file runs fine on Production under 5.6.2 - no problems. I have also checked the XML file using a syntax checker. I know this is not a syntax issue even though it looks like it.
Could someone point me in the right direction - explain what this means. Getting desperate as 5.6.3 will be going into production soon and all Bursting will fail with this error. I can't get the simplest XML File to Burst - NOTE this is only occurring on the EBS system (even running without the CM ie. a standalone java main it fails). I think this has something to do with the XML parser version and the EBS environment.
Please help...Hi Tim, good thinking - wouldn't have thought to check this file. Anyway can confirm that the problem is happening with multiple burst control files so I haven't checked the files themselves as the problem seems systemic. anyway here is an example.

I will start stripping the control files to make sure they are not the problem in the meantime. -

Is ZYBTT a new attribute? Have you changed the status of the attribute to implemented or released (in SWO1: Edit -> Change release status)?
And actually I think that your syntax is wrong too (BOR world is different compared to classes). If you want to use an attribute, I think that the syntax should be something like this:
SWC_GET_PROPERTY <Object> <Attribute> <AttributeValue>.

Parsing formatted String to Int
How can I parse formatted string to Integer ?
I have a formated string like this $900,000 and I need to convert it to 900000 so I could do calculations with it.
I tried something like this
NumberFormat nf = NumberFormat.getIntegerInstance(request.getLocale());
ttlMargin=nf.parse(screenVal);I got this exception
"java.lang.NumberFormatException: For input string: "$1,050,000""I am working on the JSP file that provides
margins,sales etc. I am reading this data off the
screen where it is beeing displayed according to the
accounting practices.
That's why I get it as a formatted string and why I
am trying covert that string to the numberScreen-scraping is a problematic, bad design. It sounds like what you really want is to call a web service which returns its results as data that a program can understand (XML, for example), not HTML (which is meant more for humans to read). I know, you probably can't change the design at this point... just food for thought. In the meantime, you'll probably have to manually parse those strings yourself by stripping out the '$' and ',' characters and then use parseInt on the result. -
How to parse a string containing xml data
Hi,
Is it possible to parse a string containing xml data into a array list?
my string contains xml data as <blood_group>
<choice id ='1' value='A +ve'/>
<choice id ='2' value='B +ve'/>
<choice id ='3' value='O +ve'/>
</blood_group>how can i get "value" into array list?There are lot of Java XML parsing API's available, e.g. JAXP, DOM4J, JXPath, etc.
Of course you can also write it yourself. Look which methods the String API offers you, e.g. substring and *indexOf.
