Java tv APIs

Hey there,
I am trying to develop a software through which I can view all tv channels(and yeah radio too) (digital + nondigital + interactive) available in my region asia on my Pentium II machine. My questions are
Q1. What hardware I use to get best results like which tv tunner card is best and which mother borad ?
Q2. What electronics equipment is necessary ? what i believe I must have a sattelite dish, LNB, reciever. But if I include decoder here too than what left here. Because if I add decoder too than what is a software for, now do you understand the functions of my software. Please please if any body have any information about it please contact me. I know I can do it with the help of java's tv api but HOW - this is my question to you ?

Don't forget to count the ones you can't see :-)
Seriously, i don't think there are any APIs for TV cards in Java. The makers of media capture equipment tend to be of the camp that writes in assembly. You're going to have to go outside of Java for this one.

Performance issue with Business Objects Java JRC API in CRXI R2 version

A report is developed using java JRC API in CR XI release 2. When I generate the report in the designer, it took less than 5 seconds to display the results in crystal report viewer inside the designer. But in the QA environment, when I generate the same report from the application, it takes almost 1 to 1.5 minutes to display the same results in PDF. I also noticed that if the dataset contains bigger volume of data, then the reports are taking even longer almost 15 to 20 minutes.
While generating the report from the application, I noticed that most of time is taken during the execution of the com.crystaldecisions.report.web.viewer.ReportExportControl Object method as shown in following line of code
exportControl.processHttpRequest(request, response, context, null)
We thought the delay in exporting the report to PDF might be the layout of the report and data conversion to PDF for such a bigger volume of data.
Then we investigated the issue and experimented quickly to generate the same report with same result set data from the application using XML, XSL and converted the output XSL-FO to PDF using Apache FOP (Formatting Objects Processor) implementation. The time taken to export the report to PDF is less than 6 seconds. By doing this experiment, it is proved that the issue is not with conversion of data to PDF but it is the performance problem with Business Objects Java JRC API in CR XI R2.
In this regard, I searched for the above issue in the SAP community Network Forums -> Crystal Reports and Xcelsius -> Java Development -> Crystal Reports. But I did not find any answers or solutions for this kind of issue in the forums.
Any suggestion, hint in this matter is very much appreciated.

Ted, The setReportAppServer problem is resolved. Now I could able to generate the report with hardcoded values in the SQLs in just 6 seconds where as the same report was generated in CRXI R2 in 1 minute 15 seconds as mentioned in the earlier message.
But, our exisiting application passes the parameter values to the SQLs embedded in the report. For some reason the parameters are not being passed to the report and the report displays only the labels without data.
As per the crj 12 samples codes, the code is written as shown below.
1. Created ReportClient Document
2. SetReportAppServer
3. Open the report
4. Getting DatabaseController and switching the database connection at runtime
5. Then setting the parameters as detailed below
ParameteFields parameterFieldController = reportClientDoc.getDataDefController().getParameterFieldController();
parameterFieldController.setCurrentValue("", "paramname",paramvalue);
parameterFieldController.setCurrentValue("", "paramname",paramavalue);
byteArrayInputStream = (ByteArrayInputStream)reportClientDoc.getPrintOutputController().export(ReportExportFormat.PDF);
6. Streaming the report to the browser
Why the parematers are not being passed to the report? Do I need to follow the order of setting these parameters? Did I miss any line of code for setting Params using crj 12?
Any help in this regard would be greatly appreciated.

How to print a document in reverse order using Java Print API ?

I need to print a document in reverse order using Java Print API (*Reverse Order Printing*)
Does Java Print API supports reverse order printing ?
Thnks.,

Thanks for the info.,

Which method implementation of Pageable interface should return the page number ?w.r.t. your first question: don't return that number but return page n-1-i when page i is requested; your document will be printed in reverse order. Your class should implement the entire interface and wrap the original Pageable. (for that number n your class can consult the wrapped interface; read the API for the Pageable interface).

Error while sending mail when using Java Mail API

Hi Experts,
I am trying to execute a webdynpro application which uses the Java Mail API to send emails. The exception that I get on executing the application is :
Sending failed; nested exception is: javax.mail.SendFailedException: Invalid Addresses; nested exception is: javax.mail.SendFailedException: 550 5.7.1 Unable to relay for [email protected]
Can anybody please help me sort out the issue.
Regards
Abdullah

Hi,
Usually one get this error if the SMTP server is configured not to relay mails (a security measure) or the SMTP server need the mail to be sent from a trusted IP or with proper authentication. Some SMTP servers are configured to block junk mails.
Pls check with your mail server administrator.

Java Persistence API and creation of databases

Hi All
I have designed a small address book application which uses a database to store the information. I have used the new Java Persistence API to take care of my transactions and querrys with the database. This works great for one set database which is generated the first time the application runs and is used all the time.
However I would like to make it so that the user can create a new address book (database) with a different name, I am not sure how I would do this using the Java Persistence API. I know the persistence.xml file must be placed in the META-INF directory of the source, so how would I be able manipulate the file or could I place the file somewhere else.
David

I am using the Derby database. I can create a database by passing the create command when I create the entity Manager like so:
Connection c = DriverManager.getConnection("jdbc:derby:AddressBook;create=true", "app", "app");My problem is that as I understand it the persistence.xml file must know the name of the database. Unless there is another way of setting this. The line in the persistence file I am referring to is:
<property name="toplink.jdbc.url" value="jdbc:derby:AddressBook"/>I wonder if I can progamatically set this value so that I have a default database in the persistence.xml and others can then create there own.

Read Attachments using Java Mapping API

Hello,
after investigating the Java Mapping API a little deeper I found some very interesting Interfaces "InputAttachments" and "Attachments" which could do exactly what is required:
Reading attachments and convert them into base64 code.
As I am not an experienced Java Programmer howeve, I am note sure how to use those interfaces.
For example there is a method defined in interface "InputAttachments":
Attachment getAttachment(String contentID)
How do I use it? If I use it in a way like "InputAttachments.getAttachment("abc");" then I get the error that it is not a static method. However how do I instantiate "InputAttachments".? As it is an interface I am not sure how to do this.
Any idea how to handle these methods?

Hi,
I am working on the similar. I am able to attach txt files and csv files but have trouble attaching xcel and pdf's. Any input is appreciated. Thanks

(Java Base API / JNI ) in tomcat

Hi All,
(this is a question I asked on the 'C-API' forum but I got no answer. I hope I'll have more success here )
I'm trying to access a database built with the C-API from a tomcat/glassfish server using the Java native API. (I need to read data produced with the C API)
I put the Environment in the application context so all user will share the same instance of the database.
first question: is it a good idea ? What would be the best practice ? can I safely use this application in a multithreaded environment ?
The problem was that the 'System.loadLibrary' method is called each time my application is re-deployed: so an exception was thrown !! (library already loaded) because the server has already loaded the db library in a previous deployment. To solve the problem I put a silent 'try... catch...' around this System.loadLibrary in the source code of com/sleepycat/db/internal/db_javaJNI.java
2nd question: is there a way to avoid this hack ?
Thank you for any answer
Pierre

The JE team does not know the answer to your question, but will see if we can find redirect it to someone who might know.

Issue with JAVA Mail API

Hi
We have a requirement to create a custom e mail. For the same I am trying to use Java Mail API.I am facing an issue with the following code:

System gives an error Sourced file: inline evaluation of: ``Properties props = new Properties(); session session1 = session.getInstance(prop . . . '' : Typed variable declaration : Class: session not found in namespace
Is there some specific API i need to import for session class. Kindly suggest.

About Java Communication API for Windows

hi
I'm studying Serial Communication in university.
I'd like to know the reason why we can't downlaod Java Communication API for Windows.
I confirmed Comm for Linux and Soralis, but I can't find Comm for Win.
Please tell me the reason if someone know.

For no particular reason Sun stopped supporting the windows version
of that package. I use rxtx which happens to allow for much faster
communication too.
The interface is identical to Sun's version, just the package differs: "gnu.io".
kind regards,
Jos

Problem in sending messages using java mail api

Hi All,
I have a problem in sending messages via java mail api.
MimeMessage message = new MimeMessage(session);
String bodyContent = "ñSunJava";
message.setText (bodyContent,"utf-8");using the above code its not possible for me to send the attachment. if i am using the below code means special characters like ñ gets removed or changed into some other characters.
MimeBodyPart messagePart = new MimeBodyPart();
            messagePart.setText(bodyText);
            // Set the email attachment file
            MimeBodyPart attachmentPart = new MimeBodyPart();
            FileDataSource fileDataSource = new FileDataSource("C:/sunjava.txt") {
                public String getContentType() {
                    return "application/octet-stream";
            attachmentPart.setDataHandler(new DataHandler(fileDataSource));
            attachmentPart.setFileName(filename);
            Multipart multipart = new MimeMultipart();
            multipart.addBodyPart(messagePart);
            multipart.addBodyPart(attachmentPart);
            message.setContent(multipart);
            Transport.send(message);is there any way to send the file attachment with the body message without using MultiPart java class.

Taken pretty much straight out of the Javamail examples the following works for me (mail read using Thunderbird)        // Define message
        Message message = new MimeMessage(session);
        message.setFrom(new InternetAddress(from));
        // Set the 'to' address
        for (int i = 0; i < to.length; i++)
            message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
// Set the 'cc' address
for (int i = 0; i < cc.length; i++)
message.addRecipient(Message.RecipientType.CC, new InternetAddress(cc[i]));
// Set the 'bcc' address
for (int i = 0; i < bcc.length; i++)
message.addRecipient(Message.RecipientType.BCC, new InternetAddress(bcc[i]));
message.setSubject("JavaMail With Attachment");
// Create the message part
BodyPart messageBodyPart = new MimeBodyPart();
// Fill the message
messageBodyPart.setText("Here's the file ñSunJava");
// Create a Multipart
Multipart multipart = new MimeMultipart();
// Add part one
multipart.addBodyPart(messageBodyPart);
// Part two is attachment
for (int count = 0; count < 5; count++)
String filename = "hello" + count + ".txt";
String fileContent = " ñSunJava - Now is the time for all good men to come to the aid of the party " + count + " \n";
// Create another body part
BodyPart attachementBodyPart = new MimeBodyPart();
// Get the attachment
DataSource source = new StringDataSource(fileContent, filename);
// Set the data handler to this attachment
attachementBodyPart.setDataHandler(new DataHandler(source));
// Set the filename
attachementBodyPart.setFileName(filename);
// Add this part
multipart.addBodyPart(attachementBodyPart);
// Put parts in message
message.setContent(multipart);
// Send the message
Transport.send(message);

Using Java Mail API from Tomcat

Hello,
Purely as an academic exercise I have written a JSP page which, upon being requested from the client's browser, should send me a default email using Java Mail Api.
here is the code :
import java.util.*;
import java.io.*;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;
public class TestMail {
    static String msgText1 = "success this time 12";
    static String msgText2 = "This is the text in the message attachment.";
    public String sendIt() {
        String to = "<my email";
        String from = "<anything>";
        String host = "<my ip address of smtp server>";
        boolean debug = false;
        Properties props = new Properties();
        props.put("mail.smtp.host", host);
        Session session = Session.getInstance(props, null);
.....The code works fine as a stand alone app but when called from JSP page it hangs on the Session.getInstance line. I can only guess that this might be a security issue with the container not allowing access to the smtp server ?
Can anyone give me a clue ???

Your Tomcat log files should spell out the problem for you.
My Tomcat installation does not come with the Java Mail API. I had to add the mail and activation jar files to the server/common.lib directory (or the server's shared/lib or the WEB-INF/lib of your application.)
HTH.

Problem in retrieving email using java mail api

hi,
In my project,i am retrieving mails from a particular email id.
I am able to retrieve the latest mails and save it in a folder in my system.
The problem is whenever i run the program eventhough the most recently received mail in inbox is retrieved and saved,again it is retrieving the same one and saving it in the same folder(not repeating).
I tried to check the newmessages in the inbox using the folder.hasNewMessage() method in java mail api,but the method is returning false only regardless new mail is there in inbox or not.
I want to read the unread messages only.Dont want to retrieve the already read mails.
I got the mail retrieving code from the below site.(sorry not posting the code because it is so long and having 4 classes)
http://www.builderau.com.au/program/java/soa/Getting_the_mail_in_receiving_in_JavaMail/0,39024620,39228060,00.htm
Can anyone tell me how to read unread mails in the inbox?
Thanks a lot
