Code for replacing 'get' and 'set' method

Hi,
I was a struts programmer but now i am a jsf programmer :-)
I was able to do the following with struts but no with jsf...
The following code in struts allowed me to have no 'get' and 'set' method in the javabean for a property (for example, the property 'name'):
ValueStack valueStack =ActionContext.getContext().getValueStack();
valueStack.set("name", "John");
ActionContext.getContext().setValueStack(valueStack);In the jsp, using the corresponding label to retrieve the 'name' property, returned value 'John'.
Is there something equivalent in jsf?

Hi, see on here.There are solutions for JSF, JBoss Seam: [Solutions for Java, JSF, JBoss Seam and Flex|http://flextrick.blogspot.com/]

Why do we need get and set methods?

It is considered good design practice to keep all class data private and
provide get and set methods for accessing the data in a controlled
manner.
So, instead of directly accessing the class data, you use getter and setters.
I do not really feel the need to use get and set methods.
How does that achieve encapsulation when ultimately the class data is being exposed?

A couple of reasons why to use get and set:
1. For example you can set an int value for month, if a user sets this to somting
higher than 12 (or 11 if it's zero based) you want to handle that by either
throwing an exception or adding a year for every time it can be devided by 12.
If you dont do it in set you'll have a whole bunch of methods that might need to
correct the value before retreiving the eventual date.
2. If for some reason you have security set up for certain values you can
implement this in the get method. When this is done somewhere else you have
a whole bunch of methods retreiving the info in other classes that need to check
first. (a canGet method could allso be used). Another good reason to use get
is when the information needs to be converted depending on the consumer
calling the get method.
3. If any logic in 1 or 2 changes you'll have a bunch of code to change.
If you feel there is no need to implement any security, error handling (on
compiling because get and set might throw something) or validation when
setting/getting these values there is still the argument of readabillity.
Eclipse has a feature that will generate getters and setters for you so it's not
like there is a lot of extra typing involved.
Got interupted whyle typig so sorry to repeat any answer given before.

Usage of AQ$_JMS_MESSAGE getter and setter methods in PL/SQL functions

Hi all,
while setting up a transformation from a AQ$_JMS_TEXT_MESSAGE to a user-defined type "msgtype" ( subject varchar2, text clob ) I tried to use the get_text() method within the transformation function but got a
ORA-25229: error on transformation of message msgid: ...
ORA-30625: method dispatch on NULL SELF argument is disallowedAccessing the CLOB part of the jms_text_message directly did not work. But within an anonymous PL/SQL procedure, get_text() works fine.
It has to be in a function to work as a transformation, but how can I do this?
Here's my current code:
CREATE OR REPLACE FUNCTION jms2msg_t(in_jms SYS.AQ$_JMS_TEXT_MESSAGE)
RETURN TxtMsgType AS
new_msg TxtMsgType;
v_oldmsg SYS.AQ$_JMS_TEXT_MESSAGE;
v_clob CLOB := EMPTY_CLOB;
BEGIN
dbms_lob.createTemporary( v_clob, true );
dbms_lob.open( v_clob, DBMS_LOB.LOB_READWRITE );
v_oldmsg.get_text( v_clob ); -- ora-30625 happens here ----------------
new_msg := TxtMsgType( dbms_lob.substr( in_jms.text_lob, 10 ), v_clob );
dbms_lob.freetemporary(lob_loc => v_clob);
RETURN new_msg;
END jms2msg_t;
/MetaLink, Oracle Docs and Google didn't help me. I know of the countermeasures against ORA-30625 in user defined types, but I cannot change JMS-Types, So, what could I do?
Regards,
Uwe

Gee, this was a no-brainer. Thanks to cut w/o paste, I lost the initializing line:
v_oldmsg:=in_jms;The uninitialized JMS object then throws this kind of "null pointer exception".
Well, at least I got to know a new ORA-code. ;-)

What is get and set methods of class

I m new for OOP concept see this is my class, How this class will return values???

            return str;

                str += "seat :" + seat.seatId +"\n"
            return str;
so, in another class where you need those variable values:
import SeatInfo;
var seatInfo:SeatInfo;
var seatsVar:Array;
var buyInLowVar:int;
var buyInHighVar:int;
seatInfo = new SeatInfo();
seatsVar = seatInfo.seats;
buyInLowVar = seatInfo.buyInLow;
buyInHighVar = seatInfo.buyInHigh;

Statistical distributions - get and setter methods

Hi,
I found the Weibull and Cauchy class here:
http://commons.apache.org/math/api-1.1/org/apache/commons/math/distribution/CauchyDistributionImpl.html
however these distributions do not seem to have methods to pick a random number within the distribution.
Does anyone have any advise on how to do that?
Thanks,
Lene

Ok, I don't see a getNextValue or getNextDouble.
Did you mean inverseCumulativeProbability?
I guess I could create a random P and then look up the x at that p, to get a random value from the distribution.
Thanks,
Lene

Bug in "Get and Set Time.vi" example for RT systems

There is a bug in "Get and Set Time.vi" that ships as an example in the "NI System Monitor" package. The routine does *NOT* return the hour correctly.
Note the string "%#H:12:39.371" as the time of day. That should be 09:12:39.371 as it was 9 AM at the time.
Mac OS X 10.8.5
LabVIEW 14-64bit
NI System Monitor 14.0.1
Pharlap RT PXI embedded system version 14.0 updated.
NOTE: it is odd that the default "New Time" has #H as the hour but that is hard wired into the VI as a sentinel case.

Rahul,
It may be only in the Mac OS X code base. But since it is one of those annoying locked VIs I can't tell. Now of course this is locked because communication with the RT system is so sensitive or just plain messy. My guess is that if I thow wireshark at it I can tell you what is inside and it shouldn't be that secret.
But let me know what you find running under Mac OS X.

Get and Set Parameter ID in BDC Call transaction

Hi all
I have written this BDC program to run a transaction eg33 to install meter. After meter get installled System generates Device location number.

i think there might be some time gap between CALL TRANSACTION and GET PARAMETER ID.....,that is to say,the new No. has not been generated and what you fetch is an old No..
i think you should use the "CALL TRANSACTION" like the following one:
CALL TRANSACTION 'EG33' USING BDCDATA MODE 'A' UPDATE 'L' MESSAGES INTO IT_MESS .
then i think you can get the right value.
P.S: the different update model(from SAP document)
       upd Effect
"A"   Asynchronous update. Updates of called programs are executed in the same way as if in the             COMMIT WORK statement the AND WAIT addition was not specified.
"S" Synchronous processing. Updates of the called programs are executed in the same way as if in the COMMIT WORK statement the AND WAIT addition had been specified.
"L" Local update. Updates of the called program are executed in such a way as if the SET UPDATE TASK LOCAL statement had been executed in it.
Other As for "A".

HashSet get() and contains() methods, by value or reference?

All the tutorials I've seen on HashSets use Strings as the object type. With Strings, it seems the get() and contains() methods work by value, not by reference.
<CODE>
String s1 = "dog";
String s2 = "cat";
String s3 = "dog";
HashSet<String> set = new HashSet<String>();
set.add(s1);
System.out.println(set.contains(s1)); //true;
System.out.println(set.contains(s2)); //false
System.out.println(set.contains(s3)); //true
</CODE>
But when I use a custom object, it works by reference:
<CODE>
MyClass c1 = new MyClass("dog", 1);
MyClass c2 = new MyClass("cat", 1);
MyClass c3 = new MyClass("dog", 2);
MyClass c4 = new MyClass("dog", 1);
HashSet<MyClass> myClassSet = new HashSet<MyClass>();
myClassSet.add(c1);
System.out.println(myClassSet.contains(c1)); //true
System.out.println(myClassSet.contains(c2)); //false
System.out.println(myClassSet.contains(c3)); //false
System.out.println(myClassSet.contains(c4)); //false
</CODE>
("MyClass" is a simple class that holds a String and an int).
Is there any way I can get the set to select by value rather than reference for objects that aren't String?
If so, is it possible that the value test could be customised, so that, for example, the above will return true if the String in MyClass is the same, regardless of the int value?

However, as DrClap pointed out, you've mis-diagnosed the problem:
System.out.println(s1 == s1);
System.out.println(s1 == s2);
System.out.println(s1 == s3));would print out the exact same results.
For an explanation why, Google "Java String pool" or try [url http://stackoverflow.com/questions/3297867/difference-between-string-object-and-string-literal]here.
If so, is it possible that the value test could be customised, so that, for example, the above will return true if the String in MyClass is the same, regardless of the int value?Absolutely. But, as others have said, you'd need to override equals() and hashCode().

How do I get and set column attributes in a table or a treetable with Java?

Using 11.1.1.4.0
Hi,
How do I get and set column attributes in a table or a treetable with Java? For a simple example, say I have a table and want certain roles to see all columns (including address), and other roles can see only certain columns (no address). In a Java method, I want to test if a table's column visible attribute is true and if so, set it to false before rendering it.
Thanks in advance,
Troy

Hi,
this use case would be a perfect example for using seeded MDS customization. Instead of checking what users are allowed to see or not upon rendering time, you have a customization class and thus the framework doing this for you.
http://www.oracle.com/technetwork/developer-tools/adf/learnmore/31-mds-sample-169173.pdf
In this paper and sample, specific users see different layouts. It also contains a customization class that shows how this can leverage ADF Security

Hi Friends,
When i am doing T.Code F-58 i am getting an error of
(No G/L accounts are defined for bank ICICI and payment method C) so could anybody please help me how to solve this problem awaiting for your reply friends.
Points will be assigned.
Thanks in advance.

Hi Kumar,
You will have to configure the House Bank with T Code FI12 and further mention the payment method in FBZP. You will have to select one of the follwing as payment method, check/transfer/postal giro transfer/bill of exchange. Though check (C) is widely used.
Assign points, if useful.

How do I get and set cookies with JSF?

How do I get and set cookies in a JSF managed bean?
Regards,
Al Malin

Below is how I did it...I am receptive to improvements.
FacesContext facesContext = FacesContext.getCurrentInstance();
HttpSession session = (HttpSession)facesContext.getExternalContext().getSession(false);
HttpServletRequest request = (HttpServletRequest)facesContext.getExternalContext().getRequest();
HttpServletResponse response = (HttpServletResponse)facesContext.getExternalContext().getResponse();
String cookieName = "myCookieName";
Cookie requestCookie = null;
Cookie[] cookies = request.getCookies();
logger.info("looking for cookie...");
if (cookies != null)
for (int i = 0; i < cookies.length; i++)
if (cookies.getName().equals(cookieName))
requestCookie = cookies[i];
logger.info(cookieName + " = " + requestCookie.getValue());
logger.info("done looking for cookie");
Cookie responseCookie = new Cookie(cookieName, "myCookieValue");
responseCookie.setPath("/");
response.addCookie(responseCookie);

I want to get and set windows system time through lab view

Hi
I want to get and set windows system time with the help of lab view 8.5.
please help me out.

You can use the call library function node. Once you drop it on your block diagram double click it and you will be able to select the dllyou want to use. Choose kernel32.dll and you will see methods listed called getsystemtime and setsystemtime. Use those
