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However, this is from memory, and a little out of date, so I could be entirely wrong.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.

How to read OVD using java

Hi all,
how to access OVD using Java?
Thanks,
Kumar.P

Hi,
You can just normal LDAP API codes to connect to OVD the same way you connect to other LDAP servers.
PFB sample code for connecting to OVD.
Properties props = new Properties();
try {
props.load(new FileInputStream("LdapCredentials.Properties"));
} catch (IOException e) {
// TODO
ldapurl = "ldap://hostname:390";
ldapUser = "cn=orcladmin,ou=Org12,dc=ovid,dc=com";
userPassword = "welcome1"; //"Killtheking123456";
userContext = "ou=Join1,dc=ovid,dc=com";
Now, you have to get Directory Context as shown below.
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
"com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, ldapurl);
env.put(Context.SECURITY_AUTHENTICATION, "simple");
env.put(Context.SECURITY_PRINCIPAL, username);
env.put(Context.SECURITY_CREDENTIALS, password);
//Initialize the Directory context
DirContext dCtx = new InitialDirContext(env);
Then you can perform search operations or new user creation etc., as you wish.
Does this help?

How to create database connection and how to call it using Java

Hi,
Good day! I'd like to know how I can create a db connection in JDev, then use this connection to retrieve data using a Java Class? I've seen using New Gallery > Database Connection. But I'm not sure how I can access this connection using Java and display some output from the retrieved records.
Any steps/tutorial link is appreciated.
Thanks in advance,

Hi,
If you need to access the connection in the entity object then refer http://download.oracle.com/docs/cd/E15523_01/web.1111/b31974/bcadvgen.htm#BABEIFAI i.e in MODEL.
But if you want to access connection in ViewController part of application then you need to do it manually.For this i am giving you my code for reference.------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

import java.util.jar.*;
public class ZipTest
    public static void main(String[] args) throws Exception
        /* create a file stream for the new zip file */
        FileOutputStream fileOutputStream=new FileOutputStream("test.zip");
        JarOutputStream zipOutputStream=new JarOutputStream(fileOutputStream);
        /* open file to add to zip file */
        File file=new File("test.dat");
        FileInputStream fileInputStream=new FileInputStream(file);
        /* create a buffer and read file into buffer */
        int length=(int)file.length();
        byte[] buffer=new byte[length];
        fileInputStream.read(buffer,0,length);

How to open MSWORD using JAVA/JNI and write the database entries into WORD

Hi..
I am searching for java codes that uses JAVA NATIVE INTERFACE (JNI) for opening MSWORD 2003.
To be brief.
I created HTML form called Employee_data.
if i click on Submit button a word document should be opened.This should be using JNI.
I have also created a servlet in jsp to process the form data and store it into database(mysql).;
Please help me to find the codes to open MSWORD on submit click and to write the database entries into word file.Can i get the full code for that.This is so urgent.
Thanks in advance.

Hi Suresh,
The easest solution I can think of is to copy the math equation from the PowerPoint then paste in the Word document directly, there's actually no way to convert it to plain text, some equation is very complext, String variable is not suitable in this case.
For example, this code works fine:
var powerPoint = new Application { WindowState = PpWindowState.ppWindowMinimized };
var oPresSet = powerPoint.Presentations;
Microsoft.Office.Interop.PowerPoint._Presentation oPres = oPresSet.Open(@"C:\test.pptx", MsoTriState.msoFalse, MsoTriState.msoFalse, MsoTriState.msoFalse);
var strObj = oPres.Slides[1].NotesPage.Shapes[2].TextFrame2.TextRange.MathZones.get_MathZones();
strObj.Copy();
Microsoft.Office.Interop.Word.Application wordApp = new Microsoft.Office.Interop.Word.Application();
wordApp.Visible = true;
Microsoft.Office.Interop.Word.Document doc = wordApp.Documents.Add();
doc.Range(0, 0).Paste();

How to load file using Java

Hello,
I am trying to load file into the TimesTen (csv or txt) using Java language. I tried using query "LOAD DATA INFILE ..." but I received error that there is something wrong in word "DATA", later I tried to copy solution from sample programs written in Java but I get a lot of error which i couldn't solve. I also tried to use ttBulkCp in Java like this: query = {CALL ttBulkCp ... } but it wasn't working as well. There must be a way to load data from file to the TimesTen table using script written in Java, right?
Thank you for any ideas.

If you take a look at the quickstart guide you get when you install the product you'll see a java code example called 'level3.java' which does what you want:
This program uses the TimesTen JDBC driver to perform order processing operations:
a) Connect to the database using the TimesTenDataSource interface
b) Process all orders in the input3.dat file by inserting into the ORDERS and ORDER_ITEM tables.....

As a guess what you are doing with that zip stuff is very odd.
You do realize that it is just going to put some binary data into the blob right? And the methods that is going to use will not necessarily create a 'complete' zip file?
If you want a zip file then just load the file, dont use the zip classes.
And if you want part of a zip file, (and want to store the parts as a zip) then extract it from the file and create another zip entity using a byte stream rather than a file.
Finally I suspect your error with the blob occurs because you do not close the statement. But at any rate you should figure out how to do the blob code independent of the zip stuff.
And what oracle driver version are you using? Some of the older ones need oracle specific handling for blobs.

I want to put an XML in a table's column using BLOBs.
I tried the following ways:
Created a table:
CREATE TABLE lob_table (id NUMBER, doc BLOB);
Created a directory:
create or replace directory XML_DIR as '\app\granite\rnd';
Created a PL/SQL procedure:
CREATE OR REPLACE
PROCEDURE BLOB_PROCEDURE AS
src_lob BFILE := BFILENAME('XML_DIR', '1.xml');
dest_lob BLOB;
BEGIN
DBMS_OUTPUT.PUT_LINE('1');
INSERT INTO lob_table VALUES(1, EMPTY_BLOB())
RETURNING doc INTO dest_lob;
DBMS_OUTPUT.PUT_LINE('2');
DBMS_LOB.OPEN(src_lob, DBMS_LOB.LOB_READONLY);
DBMS_OUTPUT.PUT_LINE('3');
DBMS_LOB.LoadFromFile( DEST_LOB => dest_lob,
SRC_LOB => src_lob,
AMOUNT => DBMS_LOB.GETLENGTH(src_lob) );
DBMS_OUTPUT.PUT_LINE('Done');
DBMS_LOB.CLOSE(src_lob);
Exception
when others then
DBMS_OUTPUT.PUT_LINE('Exception');
COMMIT;
END BLOB_PROCEDURE;
I am using Oracle SQL Developer.
When I try to run the above procedure, it says:
"Source does not have a runnable target."
When I use Toad, the procedure executes properly, but there is no blob data in the table.
Kindly help me in this regard.
