What class we can use instead of "KeyGenerator" ?

Hi all,
I am developing a J2ME application which needs encryption. But the "KeyGenerator" class is available only in J2SE. In J2ME what we can use? Could you please tell me?
key = KeyGenerator.getInstance(algorithm).generateKey();

this link will help you and search for bouncy castle api ...

What classes should I use to send/receive bytes inmediately?

What classes should I use to send/receive bytes inmediately? I mean, without using any buffers or whatever (I will implement this on my app), just the faster method.
Is InputStream/OutputStream the lowest level choice?
Thanks!

Hi!
Thank you very much for your help, I appreciate it a lot.
While I test my server, I execute ping www.myclienthost.com -t (my client games are in other office, in the same building, but different ISP) and I don't see anything strange, so I guess network is working perfectly. However, if I use wireshark (sniffer) and I see that my system fails (server does not send acks so client disconnects) is because my acks messages are not sended for 6 o 7 seconds (it should send them every 2 or 3). It seems thread is blocked. and after 6 or 7 seconds one message with 2 or 3 acks together is sent. So, I see that the thread handler blocked for a few seconds and this is doing my server is failing. Why client handler thread on my server is blocked? One question: every 2 or 3 seconds I have a thread that uses sleep that iterates thru client handlers and takes OutputStream and send one ack message for every client handler. My question is, in client handler class I have a method called SendInfo(String whatever) which encrypts and sends through OutputStream, should I protectd this method from accesing from two threads??? as acks thread and client thread can access at the same time. Could this be the problem??
EDIT: In my previous post I forgot to say what I found out with wireshark. Here I explain it. Sorry.
By the way, how can I debug threads?? I would like to know if my client thread is blocked in that critical moment.
Thanks a lot for your ideas and sorry for my English.

What Classes do you use for developing Database Applications

Hi ! (sorry for my bad english)
I develop now an application for production planning and I use an informix database-server. I have no problems with the database an the connection. I,m a database expert, but I,m a newcommer in java. What classes do you use to develop a database application ? (specially Table Handling) I tried it with JTable and AbstractTableModel. Are there better possibilities ?
JdbTable OR
JTable with DBTableModel OR
JTable with DBTableModel and DataSet
I know that this is a big question, but some little Informations can help me. (I develop with JBuilder Proffessional)
Thank you for your help.
Wolfgang

No - the classes you have described (AbstractTableModel etc) are Swing classes - that is, they are Models in the MVC GUI architecture. Database-related stuff (SQL at any rate) is contained in the packages java.sql and javax.sql - The latter is part of the Enterprise addition. You would also need to purchase a database driver (or use the sun one, which is something like com.sun.odbc.jdbc.Driver or whatever). The driver supplies you with connections to the database (java.sql.Connection).
Alternatively, you may be deploying code in a J2EE AppServer (eg. WebLogic, WebSphere etc) in which case you can use the JNDI to get a javax.sql.DataSource object (by setting one up in the AppServer and doing a lookup on it) and use this to get database Connections.
Class c = Class.forName("com.sybase.jdbc2.jdbc.SybDriver");
SybDriver sybDriver = (SybDriver) c.newInstance();
java.sql.DriverManager.registerDriver((Driver) sybDriver);
//then use Driver object to get hold of a Connection
//or alternatively using DataSources
InitialContext ctx = new InitialContext();
DataSource ds = (DataSource) ctx.lookup("jdbc/MyDriver");
Connection conn = null;
try{
    Connection conn = ds.getConnection("login", "password");
    Statement stmt = conn.createStatement();
    ResultSet rs = stmt.executeQuery("select * from MY_TABLE");
    while (rs.next()) {
      //columns are enumerated 1...n
      String s = rs.getString(1);
      //or can get by Col Name
      String str = rs.getString("name_col");
} finally {
    conn.close();
}Anyway, I hope this helps - you'll probably need to get a book on it (Java Enterprise by O'Reilly is a good one)

Why can't I install iTunes on windows RT? Is Microsoft deciding what software I can use?

Why can't I install iTunes on Windows RT? Is Microsoft deciding what software I can use?

Welcome to Apple Support Communities
Theoretically, Microsoft is deciding what apps you can install. In Windows RT, you can only install apps from the Windows Store and they must be ARM-based, things that Apple and iTunes don't meet, so you can't use iTunes in Windows RT

I want to Pick Release in 11.5.9 through API , What API I can Used?

Hi.expert
I want to Pick Release through API in 11.5.9, What API I can Used?

You need to apply patch 3438823 which provides the Pick Release Public API to create and release a picking batch and also provides the functionality to allow picking criteria of groups of items based on Item category and category sets and also provision is provided to "exclude/include only" ShipSets/SMCs in a batch.
Check Note: 435444.1 - WSH_PICKING_BATCHES_PUB Package for Pick Release Public API does not Exist in Release 11.5.9

What is the use of COMMIT in BDC?in what situation we can use it?

what is the use of COMMIT in BDC?in what situation we can use it?

Hi sunil,
Function modules that run in the update task can run synchronously or asynchronously. You determine this by the form of the commit statement you use:
COMMIT WORK
This is the standard form, which specifies asynchronous processing. Your program does not wait for the requested functions to finish processing.
COMMIT WORK AND WAIT
This form specifies synchronous processing. The commit statement waits for the requested functions to finish processing. Control returns to your program after all high priority (V1) function modules have run successfully.
The AND WAIT form is convenient for switching old programs to synchronous processing without having to re-write the code. Functionally, using AND WAIT for update-task updates is just the same as dialog-task updates with PERFORM ON COMMIT.

Does anyone know what programme i can use as iDVD is not on my mac. I want to make a DVD from a movie created on iMovie? Is Burn any good? and if so, can I get it free?

Hi does anyone know what programme I can use to create DVD of a movie that I have created on iMovie? There is no iDVD on my mac. Is Burn any good? And if so, can I get it for free?
Thanks.

There is no iDVD on my mac.
There is NO alternative. But iDVD is very easy to get.
iDVD is on the iLife 11 DISK. Buy here:
http://www.amazon.com/Apple-MC623Z-A-iLife-VERSION/dp/B003XKRZES/ref=sr_1_1?ie=U
Is Burn any good?
iDVD is vastly superior, especially for movies.

But this is a structure, do we have any transparent table which i can use instead of this structure?

Hi Vijay,
Plz use SQL trace ( ST05 ) to fetch the corresponding table.
( Activate trace, use your txn, deactivate & display trace... )
Hope this helps,

What feature I can use in SQLServer 2014/SQLAzure to Horizontal scaling in case a single machine cannot handle the load

Hi all,
I need advise for
What feature I can use in SQLServer 2014/SQLAzure to Horizontal scaling in case a single machine cannot handle the load.
Please some body suggest.
I know some features :
1.AlwaysOn
2.Peer to Peer replication
Thanks in advance.

Hello,
Windows Azure SQL database is not on-premise SQL Server 2014.
SQL database not support Always on Availability Group and Replication. Scaling out in Azure SQL Database requires sharding, which horizontally partitions data across multiple databases. You should design custom sharding solutions by using application
code across multiple databases.
If you use Azure virtual machines (VMs) with SQL Server 2014, you can configure Alwayson Availability Groups. Please refer to the following article:High Availability and Disaster Recovery
for SQL Server in Azure Virtual Machines

I want to download movie. What apps I can use?

i want to download movie. What apps I can use?

It depends what you are trying to download. If you are talking about a video from a site such as Youtube, there are numerous ways of doing this, such as www.keepvid.com. However, if you are trying to download an actual movie that is copyrighted, this is very illegal and cannot be discussed on these forums.
