GET method? Is it possible?
I'm wondering if there's a way to use the "get method" to send request either in commandlink or custom coded URL's. I want to be able to expose URLs to clients so they can bookmark them, exchange them, etc.
Thanks.
The method 'post' is coded in the render class of the <form> element, so the only way to use the 'get' method is to create your own <form> element and code the 'get' method. I do not know if the parameter will be correctly processed by the server....

No your aren't.
You are sending the data in the class.
That is what serialization does. (And actually not all data can be sent either.)
When i get the object on server, i am able to print all its fields and methods... But i have one problem. I want to invoke a simple static method that just prints "hello".. The method on client that i am trying to invoke is....You probably either need stop attempting that or re-architect the solution.
It is possible to send a class (not data) to another computer and that computer runs it. That is how applets work.
But for that to work you must send the class. And deal with how the VM loads and unloads classes (not data) as well. -
HttpURLConnection and HEAD/GET methods
I am attempting to validate whether an HTML page exists or not.
I have found that, for about 7% of the pages checked, HEAD and GET methods return different response codes.
I have structured my code such:
1) make initial check using HEAD method
2) for non valid (200) response codes, recheck the page using the GET method.
In this case about 75% of the pages that failed using the HEAD method will work when using the GET method.
So, I guess my questions are:
1) Does anybody know why HEAD/GET return different response codes?
2) Does anybody know a better way to check if a page exists?
Here is the sample program I am using with a few URLs that exhibit this behaviour:
import java.io.IOException;
import java.net.HttpURLConnection;
import java.net.InetAddress;
import java.net.URL;
import java.net.UnknownHostException;
public class Internet
private final static String DEFAULT_LOCAL_HOST = "127.0.0.1";
private URL url;
private HttpURLConnection http;
private int responseCode;
private String responseMessage;
public Internet(URL url)
this.url = url;
public boolean isValid()
try
// Make first attempt using a HEAD request
http = (HttpURLConnection)url.openConnection();
http.setRequestMethod( "HEAD" );
http.connect();
System.out.println( "head: " + http.getResponseCode()
+ " : " + http.getResponseMessage() );
// GET seems to do a better job, try again
if ( http.getResponseCode() != HttpURLConnection.HTTP_OK)
http = (HttpURLConnection)url.openConnection();
http.setRequestMethod( "GET" );
http.connect();
System.out.println( "get: " + http.getResponseCode() );
responseCode = http.getResponseCode();
responseMessage = http.getResponseMessage();
if (http.getResponseCode() == HttpURLConnection.HTTP_OK)
return true;
else
System.out.println( http.getResponseMessage() );
return false;
catch (IOException e)
responseCode = -1;
responseMessage = e.getMessage();
System.out.println( e );
return false;
public static void main(String[] args)
throws Exception
URL url = new URL( "http://www.trca.on.ca" );
Internet internet = new Internet( url );
System.out.println( internet.isValid() );
url = new URL( "http://school.discovery.com/sciencefaircentral" );
internet = new Internet( url );
System.out.println( internet.isValid() );
url = new URL( "http://www.amazon.com" );
internet = new Internet( url );
System.out.println( internet.isValid() );
}Using my sample program:
1) about 3K of data is transferred
2) it runs in about 8 seconds
Using InputStream in = http.getInputStream():
1) about 73K of data is transferred
2) it runs in about 15 seconds
Using the getInputStream() method causes the entire file to be transmitted (even though I don't use any read() methods). I don't care about the data.
I want the check to be as fast as possible which is why I use the HEAD method. It doesn't transfer the contents of the file. But why in some cases does it show a response code other than 200? -
Pass returning value of get methods to a FM
Hi experts,
I got a getter method, that returns a class value via RETURNING. Is it possible to call a FM and pass the returned parameter directly to an importing value of the FM?
e.g.
CALL FUNCTION 'MY_FM'
EXPORTING
test = my_class->get_my_value( ).
this doesn't work.
Isn't there a way to do this besides assigning the return parameter to a temporary variable and pass this one to the FM?
Thanks in advance.
Regards,
TobiHi,
Though this is not possible syntactically, there is one workaround.
Its not exactly what we want but just a thought.
You can create Public static attribute and mark it as Read only.
then you can pass the value of it directly using the classname=>attribute name.
I know its not exactly what you want but servers most of the purpose.
Regards,
Sesh -
I can't over give my variable to the return in the get Method!
Hello Java Cracks
At the moment I am working with JDOM. I am able to get access to the XML File with JDOM, but when I want to send, the value of a variable, which I get from the XML File it is not possible. When I try to send the variable to the get Method (getDtdVersion), the value I over give is always �null�. Please help me, and say what the problem is?
I also post you the second class, where I want to use the variable I over give.

Thank you very much for your help....
Your Java LearnerI suspect you are setting the scheduledtdversion member in one instance of your FileAuswahl class, but are creating yet another instance of that class and printing the member of that instance, which is null. I notice you are creating a new FileAuswahl instance each time something happens, rather than reusing the same instance.
FileAuswahl fileauswahl = new FileAuswahl();Ok, new object here. Not the same one that you previously set the scheduledtdversion member in
String dtdversion = fileauswahl.getDtdVersion();It's null of course, for the reason above. -
Getter method being called twice
Hi All,
I have a h:inputText which updates a h:dataTable as soon as the user types something into it (through the use of Ajax4JSF's a4j:support element). In this way I have something similar to a suggestionbox, but which modifies the table underneath rather than displaying a dropdownlist with possible values. My problem is that for some reason the getter method in the managed request-scoped bean to which the h:dataTable is bound, is being called twice everytime a letter is typed into the h:inputText. The first call seems to happen directly after the bean has been constructed, as the value to which the h:inputText is bound is still empty, and the second call after that, but with the correct value obtained from the h:inputText.
I searched the forums and found posts detailing similar problems, but I couldn't find an explanation of why it happens or a way to get rid of it. The common consensus seems to be to not have any processing intensive operations in the getter and to just accept that it will be called twice.
Is there really no way around this?
Thank you,
RistrettoThis is just the default behaviour of the JSF lifecycle. The first call checks if there is a default value or a value which is been set in the previous request. The second call gets the newly set value for display which is been set during the request processing. A way to get rid of the first call might be writing your own lifecycle implementation.

Validations when we use GET method
Hi Team,
I am using GET method with the following URL(example)
http://IP:8080/ords/schema_name/office/users/{user_id}
URI template : office/users/{user_id}
method:get
source type : Feed
Source : select * from emp where empno = :user_id;
Using the above URL I am able to get all the specified user details in the browser.
I want to add the validations to the service now, and response should be user defined.
Ex : when user not in the database
then respond with the error code and error name in JSON format ex:
items:
error code : 404
message: "somthing wrong"
I am not sure how we can achieve this functionality when we use SQL query.
Please suggest any possible solutions for this.
thanks
Chandrangrant dba_users view to apex and change the sql like this:
select * from emp where empno = :user_id and exists (select 1 from dba_users where username=:user_id); -
Get method in the Attribute class. in JNDI
I had connected to the AD
// Create the initial directory context
DirContext ctx = new InitialDirContext(env);
Attributes attrs = ctx.getAttribute("DC=DomainDnsZones,DC=testing,DC=local");
but I had no idea wat to get from the attrs.get method.
as in, I don't know what kind of attributes ID are available inside my attrs
is there any coding to get all the attribute ID so tat I can use the get method to retrieve them?We can get the available Attributes for a particular user.....
using Attributes class for a Search and Context....
You can try out the free LDAP viewer available in internet (Its a Applet)... u can find the possible Attribute Names in that... and use the below statement..
Attributes attrs1 = ctx.getAttributes("CN=" + "user,CN=Users,DC=domain,DC=dmn,DC=com");
String office = (String)attrs1.get("physicaldeliveryofficename").get(); -
Why Set collection has no get method implementation?
Yesterday when I was working for a requirement, I tried to use the get(Object) method in the Set. I was surprised, on seeing the interface no such method in that. I donno why?
Though HashSet was implemented through Map, I really donno the reason, why get(Object) is missing the Set Collection?
=- SaravOne might need a get method for HashSet because they need to update a field of an existing object in the set if present. And the object they currently have on hand may be equal in terms of +.equals()+ , but is not the same object in terms of == . So if they update the field of the object they have on hand, then it won't effect the one already in the set.
The "object on hand" may be an object they reuse as a lookup into the set. They simply manipulate its data so it possibly equals an object already in the set, and call HashSet#get (if such a method was present).
A contrived example that comes to mind:
public class RGB {
int rgb;
int count;
public boolean equals(Object o) {
return (o instance RGB)?rgb == ((RGB) o).rgb:false;
public int hashCode() {
return rgb;
public RGB[] aMethod(...) {
RGB lookup = new RGB();
for each (x,y) in image {
lookup.rgb = image.getRGB(x,y);
RGB inSet = set.get(lookup);
if(inSet != null)
inset.count++;
else
set.add(lookup.clone());
}Because HashSet has no get method, then a map would be needed instead. I don't think it's a really big deal though. -
Abstract class with set and get methods
hi
how to write set and get methods(plain methods) in an abstartc class
ex: setUsername(String)

and one class is extending this abstract class and same methods existing in that sub class also..... how to write......plz provide some ideas
am new to programming....
asap
thnx in advanceyes... as i told u.... i am new to coding......
and my problem is ..... i have 2 classes one is abstract class without abstract methods.. and another class is extending abstract class.....
in abstract class i have 2 methods...one is setusername(string) and getusername() ..... how to write these two methods.... in abstract class i have private variables username...... when user logins ..... i need to catch the user name and i need to validate with my oracle database and i need to identify the role of that user and based on role of that user i need to direct him to appropriate jsp page.......

Oracle.jbo.AttrValException: JBO-27019: Get method for attribute
Hi Guys,
I am trying to add a new column to Oracle quoting.It has already been customized by some consultant few years back. I followed the note 392728.1 on metalink and also have the documentation by the previous consultant but getting the error oracle.jbo.AttrValException: JBO-27019: Get method for attribute Draft in HeaderVO could not be resolved after adding my column, when I try to print the quote.
Here are the steps I took
1) added a column to the query (at the end) in HeaderVO.xml
2) added the below code in the HeaderVO.xml
<ViewAttribute
Name="DRAFT"
IsQueriable="false"
IsPersistent="false"
Precision="100"
Type="java.lang.String"
AliasName="DRAFT"
ColumnType="VARCHAR2"
Expression="DRAFT"
SQLType="VARCHAR" >
<DesignTime>
<Attr Name="_DisplaySize" Value="100" />
</DesignTime>
</ViewAttribute>
3). Modify HeaderVORowImpl.java file to add setters and getters for the newly added view attribute. For example,
a) case 67: //
setDRAFT((String)obj);
return;
b) case 67:
return getDRAFT();
c) ublic void setDRAFT(String s)
setAttributeInternal(67, s);
public String getDRAFT()
return (String)getAttributeInternal(67);
d) protected static final int DRAFT = 67;
Everything is dont exactly as per the manual but not sure why I am getting this issue. Any help will be appreciated.a) case 67: //
setDraft((String)obj);
return;
b) case 67:
return getDraft();
c)public void setDraft(String s){
setAttributeInternal(67, s);
public String getDraft(){
return (String)getAttributeInternal(67);
d) protected static final int DRAFT = 67;
can u change it as explained above.. setDRAFT should be setDraft.. and getDRAFT should be getDraft..

Can't get my class's getter method to work properly.
Hello, I am new to Java programming, although I come from C and C++. This is my first post. I am working on a basic Library application that can Checkout and Return books. Eventually I would like to add the ability to read from and write to an XML file containing data for every book.
My problem right now is that I cannot get my getter method within my Book class to work properly. When I call getData() from within main, and pass the appropriate arguments, instead of filling the variables with that object's data, it leaves them blank! Please help me.
Here is my method within the Book class, the person and id_num are private.
/* Gets general Book Instance Data and fills parameters with it */
public void getData(String n, int num, String c, String d)
n = this.person;
num = this.id_num;
c = this.checkout_date_string;
d = this.due_date_string;
}Here is how I am attempting to use it in main:
String name = "";
int number = 0;
String checkout = "";
String due = "";
Book book1;
/*Sets person = John Smith and id_num = 10763*/
book1 = new Book("John Smith", 10763);
/*Gets Checkout (todays) date and sets a due date in 2 weeks*/
book1.Checkout();
book1.getData(name, number, checkout, due);
System.out.println("Book1:\n Checkout Date: " + checkout +
"\n Due Date: " + due + "\n Is it late: " + book1.isLate() +
"\n Person who checked it out: " + name + "\n ID number: " + number +
"\n ");Then, Here is the Output:
Book1:
Checkout Date:
Due Date:
Is it late: false
Person who checked it out:
ID number: 0

Well I went ahead and made separate methods to return each value. I suppose that will work just as well, especially since now I don't have to declare a bunch of strings and int's to hold the data and pass to the method.

Well this would never work anyway
public void getData(String n, int num, String c, String d)None of those can be changed within the method. Strings are immutable and 'int' is passed by value. Each of those parameters will have the same value after the method exits as they did before it was called.
Your book class should be using 'setters' to set the value of its instance variables. -
How can I implement a get method that lets me divide two values, Help plz
I need to implement a method that divides the values return by two other methods but I keep getting an error message, I think its divide by zero error ( I am not too sure on the exact error msg as I do not have java installed on this pc as yet), here is my example,
I have two get methods that take an int value so say
getValueOne() as method one
getValueTwo() as method two
Now I have a third method that does the following,
Public int getValueThree() {
int value =0;
value = (getValueOne() / getValueTwo())
return value;
I am not two sure on the exact code but it does something like this and I get an error. Could someone please guide me how I can successfully implement a get method that divides two values that are returned by two methods.
Thanks,
ZubHi, thanks for your reply. Right, how can I go about to throw an exception? I can definitely give the exact code and error message tomorrow when I can access my home pc.
And you are right there are some values that are zero! I am not very sure what throwing an exception means to be honest. Could you please give an example?
Thanks...
