Help with java beans on initialisation

hi
I'm trying to use java beans for the first time
I'm calling a bean from a JSP page; the bean will not exist when the page is first called
<jsp:useBean id="user" scope="session" class="business.User" />I want to use properties/private attributes of the user bean to make a form "sticky" on the page, so that once the user has entered something, their input is there the next time they visit the page (eg back or via an href)
The problem is that the bean creates a user on the first call with properties that are null, which means that "null" is displayed on my form when it first appears
<td><input type="text" name="firstName" value="<jsp:getProperty name ='user' property='firstName' />"></td>I can code this out using a scriptlet but this defeats the beauty of java beans and jsp tags. How do I translate a null property so that nothing is displayed on the form?
Thanks for your help

So.. my mini-designer should be something like an editor,with a pallette with beans(like JavaBeans) and when a user is dragging a bean into a form,my applicaton should generate the code fr that bean....something like that :)

Help with java mapping

PI File adapter has a processing option u2018Empty-Message Handlingu2019 to ignore or Write Empty Files. In case there is no data created after mapping on target side then this option determines whether to write an empty file or not. But there is a catch to this option when it comes to using it with File Content Conversion which is described in SAP Note u2018821267u2019. It states following:
I configure the receiver channel with File content conversion mode and I set the 'Empty Message Handling' option to ignore. Input payload to the receiver channel is generated out of mapping and it does not have any record sets. However, this payload has a root element. Why does file receiver create empty output file with zero byte size in the target directory? Example of such a payload generated from mapping is as follows:
<?xml version="1.0" encoding="UTF-8"?>
<ns1:test xmlns:ns1="http://abcd.com/ab"></ns1:test>
solution :
If the message payload is empty (i.e., zero bytes in size), then File adapter's empty message handling feature does NOT write files into the target directory. On the other hand, if the payload is a valid XML document (as shown in example) that is generated from mapping with just a root element in it, the File Adapter does not treat it as an empty message and accordingly it writes to the target directory. To achieve your objective of not writing files (that have just a single root element) into the target directory, following could be done:
Using a Java or ABAP Mapping in order to restrict the creation of node itself during mapping. (This cannot be achieved via Message Mapping)
Using standard adapter modules to do content conversion first and then write file.
can someone help with java mapping that can be used in this case?

Hi,
 You have not mentioned the version of PI you are working in. In case you are working with PI 7.1 or above then here is the java mapping code you need to add after message mapping in the same interface mapping

 FileOutputStream out=new FileOutputStream("C:\\apps\\sdn\\rootNode1.xml");
 genFormat.execute(in,out);
 catch(Exception e)
 e.printStackTrace();
The code for PI 7.0 should also work for PI 7.1 provided you use the right jar files for compilation, but vice-versa is not true.
Could you please let us know if this code was useful to you or not?

Replace VBX Control with Java Bean

Hi All,
While compiling 6i forms in 10g I got this error of VBX Control (Obsolete)
The document says replace it with JavaBeans.
I don’t know how to replace a VBS Control with Java Bean but this is what I did, I selected the item type as Bean Area.
But the item do have a trigger
begin
control_lib.when_tab_changed(:control.tab_ctl)
end
The Package CONTROL_LIB is coded as below.
Will this code work, technically I think yes, but its always better to ask experts before I move this to test...
package body control_lib is
g_tab_id number := 0
procedure when_tab_changed
(p_tab_id number) is
l_err_txt varchar2(255);
begin
if :system.block_status != 'QUERY' then
if not good_quiet_post(l_err_txt) then
raise form_trigger_failure;
end if
end if
if p_tab_id = 0 then
rpt_ln_lib.new_tab;
elsif p_tab_id = 1 then
stat_lib.new_tab;
elsif p_tab_id = 2 then
per_acc_rl_lib.new_tab;
end if
g_tab_id := p_tab_id
exception
when form_trigger_failure then
:control.tab_ctl := g_tab_id
synchronize
end when_tab_changed
Thanks to all.

A Java bean is another technology than VBX control.
If some document says: Replace it with java bean it certainly means to use a similar java bean with a similar functionality.
I do not know a java bean, which runs VBX controls.
So you surely have to look at what yout VBX does an than to look after a proper java bean (or to write an own one).

 pls help me.

 You realy can do it like Xiang says, but the better way is to use packages. That's
 the way BEA is designed for. If you use packages you can but your bean classes
 in every subfolder beneath Classes. Here for example we have the subfolders test
 and beans:
 You have to declare the package on top of your Bean Source Code:
 package test.beans;
 In your JSP you don't need the import code of Xiang. You only have to refer the
 path of your bean class:
 <jsp:useBean id="testBean" scope="session" class="test.beans.TestBean" />
 There are some other AppServers that only can deploy Java Beans in packages. So
 if you use packages you are always on the right side.

Need Help Regarding JAVA BEAN

Is any one tell me that JAVA BEAN only used in WEB or also you in Desktop applications???? and aslo tell how i implement Java class and use JAVA BEAN. I need help regarding above matter
thanks in advance
Rehan MIrza

Here is a good link that indicate that JavaBean is not only for applets
http://java.sun.com/docs/books/tutorial/javabeans/whatis/beanDefinition.html
quote:
The JavaBeans API makes it possible to write component software in the Java programming language. Components are self-contained, reusable software units that can be visually composed into composite components, applets, applications, and servlets using visual application builder tools. JavaBean components are known as Beans.

Customize out-of-box taskflow with java bean.

Hi,
I have created a Taskflow Customization Appl. for changing out-of-the-box Profile (.jsff) pages. I create a Java bean under ‘ViewController’ project. I’ve tried to register the bean in either adfc-config.xml or faces-config.xml file. However, using EL in jsff pages to access the bean’s attribute give me errors. I referenced the bean's attribute by #{EmployeeBean.department} in .jsff file.
Where should I register the bean? What’s the difference between two config files?

Hi,
if you want to access the bean from within a bounded task flow then you configure it in the task flow definition. If the El accesses the bean from the unbounded task flow then you configure it in adfc-config.xml. When working with the ADF controller you don't use the faces-config.xml file for defining managed beans

Help with JAVA StringObject - & assign user input; StringMethod

Hi Everyone! I need help with this Java Program, I need to write a program, single class, & file. That will prompt the user to enter a word. The output will be separted by hypens and do this until the user enters exit. I think this is done by using a string variable. Then use the length of the word to setup a loop to print each letter out with hypens. (example c-a-t)
1. I think I should store the word like this: Word.Method(). Not sure of this the API was confusing for me because I wasn't sure of what to do.
2. A string method to find out how many letters are in the user's word in order to setup a loop to print each letter out. I think I can use a While loop to accomplish this?
3. A string method to access each letter in a string object individually in order to print individual letters to the screen with those hypens. This is really confusing for me? Can this be accomplished in the While loop? or do I declare variables in the main method.
Any examples you can refer me to would be greatly appreciated. Thanks

Getting user input:
This may look strange to a newbie but there's nothing much you can do since you wanted a single class file:import java.io.*
public class InputTest {
   public static void main(String[] args) {
      BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
      System.out.println("Hi! Please type a word and press enter.");
      String lineReadFromUser = in.readLine();
      System.out.println("You typed " + lineReadFromUser);
}You can get the lenght of a String using the length() method. Example: int len = "Foobar".length();
You can get the individual characters of a String with the charAt() method. Example: char firstCharOfString = string.charAt(0);
(remember that the argument must be from 0 to length-1)
You can access the documentation of all classes, including java.lang.String, at http://java.sun.com/j2se/1.3/docs/api/index.html You can also download the docs.

Help with Java Web Start

Hi everybody,
I have a simple Java application that has a JFrame containing a TextField displaying some text inside it. I am using the NetBeans IDE. I am trying to Enable Java Web start for this application. The steps I have taken upto now are:
1. Right click on Project, Java Web Start -> Enable Java Web Start. This created the jnlp file.
2. In the Resources section, I added the jar file for swing. ( I am not sure if I have to add the path for jnlp.jar etc, or are these found automatically?)
3. Right click on Project, Java Web Start -> Deploy with Java Web Start. This launches the browser with the Click me link, but on clicking this link, I get the following error.

I am not sure what it has to do with servlets, I just followed a tutorial on using Netbeans with Java Web Start, and did only the steps as mentioned in my first post. And ended up with the error.
Anyways, I added the jnlp jar files(jnlp.jar, jnlp-servlet.jar, jardiff.jar) in the WEB-INF/lib directory. And it seems to deploying it now. I can get my application to load on clicking on the "Click me" link. But the controls on my application don't seem to be working.
Also, when I try to Right click on my project -> Java Web Start -> Run with Java Web Start, I get the following error message,

Any help appreciated.

class import com.sun.org.apache.xerces.internal.impl.dv.util.Base64 not found in import.
i did not find this class in network.
can anybody help with rewriting it for jvm 1.3.1?
thanks in advance.
code below:
import com.sun.org.apache.xerces.internal.impl.dv.util.Base64;
import java.io.*;
import java.security.Key;
import java.security.KeyStore;
import java.security.PrivateKey;
import java.security.Signature;
import java.security.cert.Certificate;
public class Sign {
public static void main(String[] args) throws Exception {
// TODO code application logic here
BufferedReader reader = new BufferedReader(new FileReader("c:\\cert.p12"));
StringBuilder fullText = new StringBuilder();
String line = reader.readLine();
while (line != null) {
fullText.append(line);
line = reader.readLine();
KeyStore p12 = KeyStore.getInstance("pkcs12");
p12.load(new FileInputStream("c:\\cert.p12"), "Hfrtnf$5".toCharArray());
//????????? ????????? ????, ??? ????? ????? ???????????? alias ? ??????
//Key key = p12.getKey("my kkb key", "ryba-mech".toCharArray());
Key key = (Key) p12.getKey("my kkb key", "Hfrtnf$5".toCharArray());
Certificate userCert = (Certificate) p12.getCertificate("my kkb key");
String base64Cert = new String(Base64.encode(userCert.getEncoded()));
//signing
Signature signer = Signature.getInstance("SHA1withRSA");
signer.initSign((PrivateKey) key);
signer.update(fullText.toString().getBytes());
byte[] digitalSignature = signer.sign();
String base64sign = new String(Base64.encode(digitalSignature));
String base64Xml = new String(Base64.encode(fullText.toString().getBytes()));
System.out.println("<certificate>" + base64Cert+"</certificate>");
System.out.println("<xmlBody>" + base64Xml+"</xmlBody>");
System.out.println("<signature>" + base64sign+"</signature>");

My first search is to see if there is an Apache commons project that provides it. Lo and behold:
http://commons.apache.org/codec/apidocs/org/apache/commons/codec/binary/Base64.html
commons-codec.
