Help regarding Java
Can java work on Dos Operating System ???.
Sun Java (and all derived versions) will not work on MSDOS (or any of its derived versions.) There was supposedly something that ran and was named Java(?), but no more. If you mean a DOS (Disk Operating System) other than MSDOS, I have no idea.

Need help regarding Java decoding of IMAP attachment (IOStream related ques
Hi ,
I need some help regarding the processing of an IMAP attachment , It is a basic IOStream related question I guess.
I have some attachment to a mail , I try to fetch it using javamail and read the content and write it to a file , I was able to do it successfully when I was using stream.read( tempBuffer) function but when I started using stream.read( tempBuffer, 0, m_maxDataSize ); it is giving me following exception
java.io.IOException: Error in encoded stream: needed at least 2 valid base64 characters, but only got 1 before padding character (=), the 10 most recent characters were: "/59PT/eXQ="
at com.sun.mail.util.BASE64DecoderStream.decode(BASE64DecoderStream.java:259)
at com.sun.mail.util.BASE64DecoderStream.read(BASE64DecoderStream.java:148)
***Here is the snippet of code that is running this:***
m_contentObj = m_message.getContent();
if(m_contentObj instanceof InputStream)
System.out.println(" Content is type of InputStream");
InputStream stream = (InputStream) m_contentObj;
byte[] tempBuffer = new byte[m_maxDataSize];
stream.skip( m_currPos );
int bytesRead=stream.read( tempBuffer, 0, m_maxDataSize );
System.out.println(" Read the following no of bytes from the Object::"+bytesRead);
m_currPos+= bytesRead;
Please suggest what to do.
Thanks & Regards

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 MIrzaHere 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.

Hi All,
I am a bit confused witht the shortcut syntax for adding action listeners for event handling.
In the Java tutorial it is mentioned that for implementing an event handler following are the three steps:
1. Create a class that implements ActionListener interface.
For example:
public class MyClass implements ActionListener {
2. Registers an instance of the event handler class as a listener on one or more components.
For example:
someComponent.addActionListener(instanceOfMyClass);
3. In the event handler class, a few lines of code implement the methods in the listener interface.
For example:
public void actionPerformed(ActionEvent e) {
...//code that reacts to the action...
In the tutorial a shortcut syntax is also given:
For Example:
Class TestApp {
JButton btn = new JButton("Test");
btn.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
...//code that reacts to the action...
My doubt is:
1. How are we allowed to create an instance of ActionListener which is an "interface". (doesnt addActionListener expect instance of a class that implements the ActionListener interface? )
2. How are we able to access local variables of class "TestApp" the inside the actionPerformed() function.
Could anyone explain more about this shortcut syntax of adding action listeners?
Thanks in regards
ArunThe example uses so-called "anonymous inner classes". ActionListener is an interface, of course. But if you use the construct
new ActionListener() {
public void actionPerformed(ActionEvent e) {
...//code that reacts to the action...
}this is about equivalent to defining an inner class
private class MyActionListener implements ActionListener {
public void actionPerformed(ActionEvent e) {
...//code that reacts to the action...
}and using that class. The difference is mainly, that the in nthe shortcut notation the class has no explicit name, it is anonymous.
There are advantages and disadvantages to that. The main disadvantage is, that you create a large amount of classes in this way. I've read somewhere, that SUN is planning to rewrite the examples without the use of anonymous inner classes. -

Urgent help regarding Java regular expressions.
hello everyone,
I am trying to parse a html file which contains
dyn.Img("http://www.boston.com/news/nation/articles/2007/06/21/bill_clinton_takes_bigger_campaign_role&h=306&w=410&sz=13&hl=en&start=43","","QFo9lqKeMR7uzM:","http://cache.boston.com/resize/bonzai-fba/AP_Photo/2007/06/21/1182410228_1931/410w.jpg","125","93","\x3cb\x3eBill Clinton\x3c/b\x3e takes bigger campaign \x3cb\x3e...\x3c/b\x3e","","","410 x 306 - 13k","jpg","www.boston.com","","","http://tbn0.google.com/images","1")
the given above function many times. I have to fetch the whole functions into an array. So i have to write a regular expression which recognises the whole above string.
Can anyone please help me.
Thank you,
chaitanyawell if this is all you want
http://cache.boston.com/resize/bonzai-fba/AP_Photo/2007/06/21/1182410228_1931/410w.jpg
You can always substring it like chuck said
***BUT all the images would have to be .jpg for this to work***
back = we.indexOf(".jpg");
int x = 0;
while (back < web.lastIndexOf(".jpg"))
back = web.indexOf("http",back+1);
picture[x] = web.substring(front, back);
x++;
front = back;
} Might not be the best code but it worked with a website i had to parse

XI Mail Adapter: sending emails with attachment with help of java mapping
Hi ,
On trying out the scenerio mentioned in the blog, using the java mapping provided
"XI Mail Adapter: An approach for sending emails with attachment with help of Java mapping
The scenerio works just fine.
But the payload as the content of the attachment is not getting generated in proper XML format.
I suppose it's because of the replace special characters code part..
Can anyone help me state the modification required in the code.
Thanks!
Regards,
Faria MithaniIt might be a codepage issue. Is your original payload UTF-8?
-
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

In case you are working in PI 7.0 you can use this code

TransformerFactory tf=TransformerFactory.newInstance();
Transformer transform=tf.newTransformer();
if(docIn.getDocumentElement().hasChildNodes())
docOut.appendChild(docOut.importNode(docIn.getDocumentElement(),true));
transform.transform(new DOMSource(docOut), new StreamResult(out));
else
out.write(null);
catch(Exception e)
public void setParameter(Map arg0) {

public static void main(String[] args) {
// TODO Auto-generated method stub
try{
RemoveRootNode genFormat=new RemoveRootNode();
FileInputStream in=new FileInputStream("C:\\apps\\sdn\\rootNode.xml");
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?

Help regarding :Video Segmentation & Summerization
hello friends,
I am doing my project on above topic and I am trying it with Java.
Is it possible doing it in Java.
What Techniques I'm using are:
1.Java(JMF)
2.Oracle 9i(Inter-Media)
3.Matlab
This project concludes of four parts
1.Segmentation (Video to Image conversion)
2.Comparison (Copare frame using algo.)
3.Extraction (remove duplicate frames based on algo)
4 Summarization (Collect frames and form a new content based video)
Is It possible in Java? How?
Seeking for help regarding this .
Thank you.This project concludes of four parts
1.Segmentation (Video to Image conversion)
2.Comparison (Copare frame using algo.)
3.Extraction (remove duplicate frames based on algo)
4 Summarization (Collect frames and form a new content based video)So, compressing that into a simple question instead of a convoluted one... you just want to remove duplicate frames from a video and save it to file? -
in Office 2011 the function "share it by e-mail" seems to be disabled. that happened recently, just after the apple update regarding Java. Any idea on how enable this function again?
I was able to get to a support person who helped me fix this without charge. I guess it was my bad for not trying the right way to access support.
Anyway, they answer is this.
I had to create a new account on my computer. When I logged into the new account it immediately wanted an AppleID. I used my daughter's e-mail address for the AppleID. This setup the internet accounts correctly with her iCloud.com e-mail address. I was then able to access e-mail in both the browser and Mail. Not that complicated but nothing that I would have easily thought up on my own.
Thank Apple Support! -
