How to send attachments using java application and outlook
Hi ,
I created an application in java which is as
on the Conference Tab i can schedule a conference and with the send command on page it map all the scheduled data to outlook(with all conference details) and using outlook send option the mails are send to appropriate user.
but now i want to modify this application such as when i use the send command from my jsp page it should attach the file that is in .vcs or .ics format for auto updation of user calender.
can any one know how to send attachment using java application .Last time I checked, SMS was a service between carriers and doing SMS yourself was really tricky. Some services existed to let you do it but as I recall they wanted non-trivial money.
However, most phone carriers provide an email-to-SMS bridge of some kind.
So the easiest thing is just to send an email.
That's sending from a non-phone to a phone. There's a J2ME library to send/receive SMS from/to a phone.
However, this is from memory, and a little out of date, so I could be entirely wrong. Hope it helps anyway. -

Communication with database using TCP sockets connection
Hi all,
I am bit of a newbie when it comes to databases. In a project I realised over te passed few weeks, I communicated with an 11g database using an application I created with VS Express. It uses an ODBC connection. I now want to connect a PLC to the same database. These PLC's don't have the ability to install an ODBC client so I need something different.
I am easily able to open a TCP socket on the PLC and send data from there. I would like to know if I can start a TCP sockets connection with our 11g server and send all queries directly. The other (already suggested) option would be to have the PLC connect to a PC that reads this information and hands it over to the ODBC connector, but that would mean I need an extra PC just to 'translate'.
I have been searching these forums for socket, TCP and more and feel it is possible, but I need a good document as a reference to show/tell me how it's done.
Thanks in advance,
MarijnThe TCP/IP interface to Oracle is undocumented (and hugely complex anyway). You'll need to use a higher layer iterface or setup your own infrastructure.
We need more information about what is available to you inside the PLC.
Can you use Java? If so, perhaps use thin JDBC?
Can you sent HTTP requests? If so you could set up your own Web services to handle this.
If you can only use C or C++, Oracle has interfaces there too.. it's called OCI (Oracle Call Interface) and thats as close to the networking layer as you can get.
Finally if you can use .NET Oracle has a Fully Managed Oracle Data Provider for .NET that you could use.
But if all you can do is super low level network access and none of the above then you will need to set up an intermediary as you mentioned. -

Problems sending files throught TCP sockets
I would like to transfer a file throught a tcp socket, here there is what the sender program does :
try{
File localFile = new File("shared/"+fileName);
DataOutputStream oos = new DataOutputStream(socket.getOutputStream());
DataInputStream fis = new DataInputStream(new FileInputStream(localFile));
while(fis.available() > 0){
oos.writeByte(fis.readByte());
catch(Exception e){}here what the receiver program does:
try{
File downloadFile = new File("incoming/"+fileName);
downloadFile.createNewFile();
ois = new DataInputStream(connectionSocket.getInputStream());
fos = new DataOutputStream(new FileOutputStream(downloadFile));
while(ois.available() > 0){
fos.writeByte(ois.readByte());
catch(Exception e){}
}Where i m wrong? it doesnt work :( , it just create the new file in the incoming folder, but its size remains 0 byte :(
help a newbye please :DYour problem is probably related to the use of available. This is the amount that is currently in the buffer that you can read without blocking. For network programming you should expect to have to wait for data. Second, you are copying the data one byte at a time which is not very efficient. Try something like:
// Sender
try {
File localFile = new File("shared/"+fileName);
OutputStream out = socket.getOutputStream();
InputStream fis = new FileInputStream(localFile);
int length;
byte[] buffer = new byte[4096];
while((length = fis.read(buffer)) != -1)
out.write(buffer, 0, length);
fis.close();
out.close();
catch(Exception e){}
// Receiver
try {
File downloadFile = new File("incoming/"+fileName);
IntputStream ois = connectedSocket.getIntputStream();
OutputStream fos = new FileOutputStream(downloadFile);
int length;
byte[] buffer = new byte[4096];
while((length = ois.read(buffer)) != -1)
fos.write(buffer, 0, length);
fos.close();
ois.close();
catch(Exception e){} -
How to send data using serial Communication
I want to make serial communication using RXTXcomm.jar file.I was written the code.From this I got the list of serial ports avilable on pc but then after when I was tring to send command to machine which is attached to port it didn't gave any reply.
Tell me that how to send command to port?This is how I do it:// open port, get ownership
SerialPort serialPort= (SerialPort)portId.open(APPLICATIONNAME, timeout);
// no framing and no threshold
serialPort.disableReceiveFraming();
serialPort.disableReceiveThreshold();
// communication speed, parity, stopbits and databits
serialPort.setSerialPortParams(BAUDRATE, SerialPort.DATABITS_8,
SerialPort.STOPBITS_1, SerialPort.PARITY_NONE);
// no handshaking or other flow control
serialPort.setFlowControlMode(SerialPort.FLOWCONTROL_NONE);
// timer on any read of the serial port
serialPort.enableReceiveTimeout(TIMEOUT);
// open streams for reading and writing
InputStream is= serialPort.getInputStream();
OutputStream os= serialPort.getOutputStream();... then you use the 'os' stream for writing and the 'is' stream for reading.
kind regards,

How to send XML using UTL_HTTP
I am trying to workout how to send XML data to a webserver using UTL_HTTP but am not getting any reply
I need to submit the following XML document to a server "http://api.fastsms.co.uk/api/xmlapi.php" Their instructions are "The XML Document should be posted unencoded, with a UTF-8 character set as parameter 'xml'"
If I submit the following XML on their test form
<?xml version="1.0"?>
<apirequest version="1">
<user>
<username>**USER**</username>
<password>**PASSWORD**</password>
</user>
<application>
<name>Example Application</name>
<version>1.0</version>
</application>
<inboundcheck lastid="10711399"/>
</apirequest>
I get an XML response back with the messages in my inbox.
This is the code I am trying to use to accomplish the same from PL/SQL : I know a response is coming back as there is header information - just no content. What am I doing wrong ?
l_xml VARCHAR2(5000);
req utl_http.req;
resp utl_http.resp;
header_name VARCHAR2(256); -- Response header name
header_value VARCHAR2(1024); -- Response header value
response_text VARCHAR2(4000); -- Response body
l_url VARCHAR2(100);
BEGIN
l_xml := 'xml=<?xml version="1.0"?>';
l_xml := '<apirequest version="1">';
l_xml := '<user>';
l_xml := '<username>**USER**</username>';
l_xml := '<password>**PASSWORD**</password>';
l_xml := '</user>';
l_xml := '<application>';
l_xml := '<name>Example Application</name>';
l_xml := '<version>1.0</version>';
l_xml := '</application>';
l_xml := '<inboundcheck lastid="10711399"/>';
l_xml := '</apirequest>';
-- Open HTTP connection
l_url := 'http://api.fastsms.co.uk/api/xmlapi.php';
req := utl_http.begin_request(l_url,'POST',utl_http.HTTP_VERSION_1_1);
-- Set headers for type and length
utl_http.set_header(req,'Content-Type','application/x-www-form-urlencoded');
utl_http.set_header(req,'Content-Length',to_char(length(l_xml)));
-- Write parameter
utl_http.write_text(req,l_xml);
-- Read response file
resp := utl_http.get_response(req);
-- Print out the response headers
FOR i IN 1 .. utl_http.get_header_count(resp) LOOP
utl_http.get_header(resp,i,header_name,header_value);
logging_pkg.info(header_name || ': ' || header_value);
END LOOP;
-- Print out the response body
BEGIN
LOOP
utl_http.read_text(resp,response_text);
logging_pkg.info(response_text);
END LOOP;
EXCEPTION
WHEN utl_http.end_of_body THEN
logging_pkg.info('End of body');
END;
-- close http connection
utl_http.end_response(resp);
EXCEPTION
WHEN utl_http.end_of_body THEN
utl_http.end_response(resp);
END;
Cheers,
BrentHi Billy
Yikes - how embarassing ! Thanks for pointing out my beginners mistake there. I've fixed my code - and also implemented the substitutions of parameters like you suggested - I like that approach.
Unfortunately the end result is no better - the line
utl_http.read_text(resp,response_text);
Still returns nothing back
The headers that are coming back are
Date: Thu, 04 Jul 2013 08:31:56 GMT
Server: Apache/2.2.16 (Ubuntu)
X-Powered-By: PHP/5.3.3-1ubuntu9.3
Expires: Thu, 19 Nov 1981 08:52:00 GMT

Pragma: no-cache
Vary: Accept-Encoding
Content-Length: 0
Content-Type: text/html; charset=UTF-8
Connection: close
I guess I will need to try chasing it with the fastsms vendor so see if they can check my incoming request and see if there are any glaring problems. I know the xml is correct as I am now logging the xml string just before I send it and when I take that string and put it in their test form it works perfectly - something else in the puzzle is missing. I've had no experience using utl_http before - perhaps it's no possible to read the xml repsonse using this ?
Anyway, thanks for your help Billy.
ps - How do you paste your code into your message to get that formatting ?
Cheers,
