Get method
Hi
I'm wondering if there is a way in Java to get a Method object directly from using the method name. As in the manner of MyClass.class. Something like MyClass.methodName.method?
Thanks,
Mike

Refering to the asker in the third person is less than polite. Jesus Christ. If you're really upset about that then the internet is not for you.

Wrong again. That poster is some guy from India who doesn't know what he's doing. And he's asking YOU a question in order to understand your post better.
Obviously this is the wrong place to ask questionsClearly you're a complete idiot.
So essentially because someone said OP and you didn't know what that means you flew off the handle? Pathetic.

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..
and make sure that the index.. number is exactly matching with the attribute order in the VO -
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?

I had a working JSP/Struts application. I added a new data page and struts forward, and started getting:
No getter method for property Fullname6 of bean org.apache.struts.taglib.html.BEAN
errors.
I have confirmed that the Fullname6 is referenced in the UIModel.xml file. My changes were only to add a read-only table to the jsp that is failing, so I don't see how that could be causing this error. I made no changes to the struts action that forwards to this page.
What is going on here? Anybody have any ideas?I know about the link that you've sent.
We don't have a specific form bean for this, as we have 'DataForm' which takes care of get/setter method for the attributes. I am using ADF, JSP, Struts and parameterized where clause in my VO. I do not know how to procede as it doesn't allow me to create the form bean.

Null pointer exception in getter method
I am trying to have a getter method that returns a collection. The method is supposed to get a list of files from a directory and returns the collection. I am instantiating the List in the method and the converting an array into the List using asList. Then I am trying to return the list to the main method.
When I put this code in the main method I get the result I want, but when I try to put it in the getter method and call it from main I get a NullPointerException compile error.
I need help understanding what I am doing wrong when I move this code out of the main method and into another non static method.I was looking around at other posts and noticed they
give more code than I was. I was trying to save you
some reading but now I see I just made it harder.No problem. It can be difficult to know just how much code to post to get all the relevant stuff but not a bunch of extraneous junk.
The problem is you have two different currentDirectory variables. The member variable (declared just inside public class FileBrowser and a method (or "local") variable declared in main. The local one in main hides or shadows (those two terms are similar in Java, and I forget the details of which is which) the member variable.
When you set the one in main, it doesn't affect the member variable. The local one in main only exists inside of main.
To fix this, change this line inside of main: File currentDirectory = new File(System.getProperty("user.dir")); to this: currentDirectory = new File(System.getProperty("user.dir")); By having the class name File there you're declaring a new variable. Without the class name, you're just using the existing member variable. -
**URGENT** No getter method for property searchText of bean org.apache.stru
I'm implementing a query page as described in the HowTo ADF_ComplexMasterDetail.zip
When running the query page, I'm receiving the error:
javax.servlet.jsp.JspException: No getter method for property searchText of bean org.apache.struts.taglib.html.BEAN
I have my searchEmployees writen and 'exposed' (at least I can see it in the Data palette). But seems like something is missing, and can't find this searchText beam property specified in the html:text tag.
Can someone help in this one?
Here is the Help description inside the HowTo example:
Section 3
queryEmployees
queryEmployeesInDept provides an interface for entering a simple search criteria for querying a list of
employees. This does not use the Find mode Query By Example functionality that the other query screens
use, but rather presents a much simpler search interface. The actual search is carried out using a
function
searchEmployees that the underlying view object exposes. (See the EmployeesView view object in the
model project)
1. Drop a new Data Page onto the page flow diagram call it queryEmployees
2. In the page flow diagram, drag the searchEmployees operation from the AllEmployeesView
collection in the Data Control Palette and drop it on top of the new Data Page. This will cause the
framework to run a search whenever the page is called.
3. In the Structure pane, locate the queryEmployees node and expand it, select the child node
paramNames[0], and change it's value attribute to ${param.searchText}. This will pass the URL
parameter searchText on to the business method to qualify the query.
4. Drill down into the page and expand the Data Control Palette to select the AllEmployeesView
collection. Set the Drag and Drop as: list to Read-OnlyTable. Then drag the collection onto the page.
This will create a tabular containing the query results.
5. Select the Struts HTML component palette and drag a Form onto the page above the output table. Set
the handling action to this Data Page (queryEmployees.do)
6. Drag a text field from the component palette inside of this new form. Set the property attribute of
the
<html:text> tag to searchText (the same value you used in the paramNames[0] for the Data Page)
7. Create a new submit button in the form to submit the search. Set the property attribute of the button
to
event_search.
8. Finally we need to subclass the data page to prevent the search action from being fired when it is not
appropriate for the page ( for instance when we first display it). To do this we need to Go to Code on
the Data Page's context menu, and override the invokeCustomMethod() method:
* We only want to invoke the custom method i.e. the call to change
* the Where clause on the collection, if the Action has been called with
* a search event on the page with a search term supplied.
* If the user got here via a link or another event, we bypass the model call
* unless a URL parameter event=search is supplied, in which
* case the method will also be called.
protected void invokeCustomMethod(DataActionContext actionContext)
List events = actionContext.getEvents();
// If the event is "search" do the custom event call
if ((events != null) && (events.contains("search")))
String searchTerm = (String)((DynaActionForm)actionContext.getActionForm())
Get("searchText");
if (searchTerm != null)
super.invokeCustomMethod(actionContext);

Authentication syntax for HTTP GET method using TCP functions in Labview on linux
Hi,
Currently, I am trying to communicate to web server. I have Labview installed on a Linux machine. The HTTP function blocks and other labview functions do not work. Hence, I am building a HTTP code string using TCP functions (port 80) to talk to the web server. I am successfully able to fetch a response from web sites (example www.ni.com) from my vi. However, when I try to communicate to my web server, it does not work. It requires an authentication. I am able to open http://ipaddress in my browser from my machine using username and password. Can someone help with Authentication string requirement for GET method?
so far the string is:
GET /index/ HTTP/1.1
Host: http://xx.xx.xx.xxAn easy option would be to try http://userassword@server syntax for the URL.
Else I posted a Twitter fetcher once (won't work anymore since Twitter moved to Oauth authentication) at LAVA. Based on code from @cloew.
The code is part of this LLB.

Problem extending standard ViewReceiptsSearchVO view object with logic on get method
Hi All,
EBS 12.1.3
Database 11.2.0.3
I am trying to extend the 3 VOs related to ViewReceiptsSearch. I extended a seeded ViewReceiptsSearchVO view object. I haven't made any changes yet, no columns added, nothing altered. When I run this substitution, the "Received" column is null. This column in the view used for the view object only selects NULL and uses the getter method for the attribute to populate the value. The generated extension getter calls getAttributeInternal and skips the logic in the standard getter and the substituted view object is displaying the null in the screen. The below discussion explains the problem very well except that the original posted had the issue in 11.5.10.2. I am having this issue with 12.1.3.
Problem extending standard view object with logic on get method
The 3 VOs that I am having the problem are:
ViewReceiptsSearchVO
ViewReceiptsSearchReqVO
ViewReceiptsSearchSupplierVO
What do I need to do to get the "Received" column populated? Please let me know any additional information you want to troubleshoot the issue.
Thanks.Hi,
Can you Please Share Extended ViewReceiptsSearchVO.xml and .jpx File?
Thanks,

Retrieving image using HTTP GET method?
I want to send a image to a client browser. My servlet's HTML response to the client browser contains the <img src="..."> tag. The client browser uses the HTTP GET method to call my servlet's DoGet method, and I must transfer the desired image to the client browser in this DoGet method at servlet. Now, the problem is that, what should be the source URL in the image(img) tag that is present in my servlet response to client?
For eg: the img tag should be like this
<img src="http://<hostname>:<portname>/<servletname>/...?[var1=value1]">
Now at the ellipsis that you see in the above source URI, I want to write the type of image file (something.jpg) ,so the browser knows what kind of image file it is.
To sum it up...how to get the image using DoGet method and <img src="...">
Regards,
AmitTo give you a better idea on what's happening, read the RFC:
(HTTP/1.0) http://ftp.ics.uci.edu/pub/ietf/http/rfc1945.html
(HTTP/1.1 - compressed data)
http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html
If you for example execute the command by telnetting to port 80 on a server:
GET http://somewhere.com/some.jpg HTTP/1.0<cr>
<cr>You will get this header:
Trying 217.22.64.73...

A webserver usually maintains a list of file extensions by which it will determine the correct MIME type to emit, when a resource is retrieved.
The browser reads the header, and decides what to do with it, in combination with (X)HTML markup.

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? -
Value Change event is not working. Html Panel Grid get method is not called
Hi,
I'm creating components dynamically.
I have a dropdown. Based on the selection of dropdown, the panel grid is getting called.
First time the panel grid getmethod is getting called. But when i change the value of drop down, panel grid get method is not getting called and its not rendering.
This is the code:
JSF:
<h:panelGroup>
<t:selectOneMenu id="selectProjectTypes" onchange="sbmitform();" immediate="true" valueChangeListener="#{ProjectController.projectTypeChanged}" value="#{ProjectController.project.selectProjectTypes}">
<f:selectItem itemLabel="--------------------" itemValue="-1"/>
<f:selectItems value="#{ProjectController.projectTypesList}"/>
</t:selectOneMenu>
</h:panelGroup>
<h:panelGrid columns="2" rendered="#{ProjectController.projects}" id="test" binding="#{ProjectController.defaultValues}" columnClasses="hunderadfifty" cellpadding="5" />
Controller:
public void projectTypeChanged(ValueChangeEvent event) throws AbortProcessingException,Exception {
String nodeTypeId = null;
String selectedValue = (String)event.getNewValue();
getSessionCache().addValue("test", 0, "1");

}Hi,
I'm having the exact same problem, and it's freaking me out!!! The setGridPanel method is always called but not the getGridPanel. This one is only called the first time the page is rendered, and when I change a drodpdownlist it never gets the gridPanel again! I'm using an HtmlPanelGrid. Anyone can help please?
Thanks in advance,

Why is the ejbstore() called when i invoke any getter method of my bean ?
Hi All,
I have designed one enterprise bean with three attributes title , type and date.
and i have implemented getter and setter method for these member variables.
When i call any one of getter methods,
the output at server as follows :
getTittle();
ejbStore();
getType();
ejbStore();
I want to know why the ejbStore() is called as soon as i called any one of getter methods.
I heard ejbLoad() and ejbStore() are invoked by container based on transaction attribute.
I even set "Never" as transaction attribute . Still i got a same type of output.
Could you explain me why it happens ?
Thanks in advance,
nvseenuHi magesh ,
Hi
ejbStore is called if any of the three is true:
. A tx completes and the bean participated in the Tx
and atleast one business method was called. Note that
getters are also business methods.
2. A Finder method is called within the tx, which
causes ejbStore() to be called by the container
(before the finder executes)
3. The method is marked using
"flush-et-end-of-method" attribute in
sun-ejb-jar.xml.
I understood the concepts explained here.
>
I am surprised that TX_NENVER causes ejbStore(). Can
you send us the ejb-jar.xml and sun-ejb-jar.xml?The thing which confuse me is why ejbStore() is called for Transction attribute
"Never".
My ejb-jar.xml file is as follows:
<!DOCTYPE ejb-jar PUBLIC
"-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 2.0//EN"
"http://java.sun.com/dtd/ejb-jar_2_0.dtd">
<ejb-jar>

<prim-key-class>test.BarronsPK</prim-key-class>

<res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>
</entity>
</enterprise-beans>
<assembly-descriptor>
<container-transaction>
<method>
<ejb-name>BarronsEJB</ejb-name>
<method-intf>Remote</method-intf>
<method-name>*</method-name>
</method>
<trans-attribute>Never</trans-attribute>
</container-transaction>
</assembly-descriptor>
</ejb-jar>
BarronsBean has three member variables " id , title , type " and gettter and setter methods for these variables.
I use JBoss App Server to run EJB.
I feel information i have given here may be enough to you to explain me why ejbStore() is called after any one of the getter / setter method is invoked.
Thanks in advance,

How do you find what bin your clips are in??
I was wondering if there is a way to tell where a clip in the timeline came from. Sometimes a project will have footage from other projects and bins. I would like to find out what bin a specific clip is in from the timeline. Thanks alot!
