Opening a URL from a Java Program

Hi all,
Can I open Internet Explorer and invoke a URL from a Java Program. If it can be done, could someone please give a code for that.
Thanks in advance.

Did you try it like "start \"http://java.sun.com\""
or maybe
"start 'http://java.sun.com'"I've no idea whether that will work, but it would be the first thing I'd try.

Opening an URL from a JAVA application

hi,
iam new to Java.
Currently iam designing a simle GUI which takes input(URL) from user in a test field and has a button.Upon clicking button i want to open the webPage specified by that URL in a default webBrowser.
How can i do that(opening webPage)?
advanced thanks for your help.
vd.rach

getting an error on that line as follows: "unreported
exception; must be caught or declared to be thrown".exec() throws IOException so catch it.
try {
Runtime.getRuntime.exec(...);
catch(IOException e) {
System.err("Cannot launch the browser: " + e.getMessage());
}On the side note: I found javaworld's [url http://www.javaworld.com/javatips/jw-javatip66_p.html]solution most useful in serving this purpose in a project, even though its a little bit platform specific.

Opening a document from a java program.

Hi,
Just wondering if anyone could help me???
I have a simple java GUI based Program and i want to open up a pdf document when i press a button or click on a hyperlink. ( i want it to open in it's own window (ie launch in adobe acrobat reader) and not be displayed in my application itself).
I have tried using:
runtime.exec("c:\myfile.pdf");
But this does'nt seem to work and is returning the following error:
java.io.IOException: Create Process: c:\myfile.pdf error = 2
Can't understand why this is'nt working.
Any ideas??

thanks,
Itried this and now nothing happens when i press the button
Here is my code:
try
Runtime.getRuntime().exec("cmd /h Hullo.pdf");
}catch(IOException e)
{System.out.println(e);
}//end catch
the document is called Hullo.pdf and it is stored on the H drive

On trying to open a URL from an external program or a saved webpage I get an error saying "There was a problem sending the command to the program." It did not do this in the last version I was using, I am now using FIrefox 8.

It happens with all programs, including the default Explorer.exe (for saved pages).

It somehow decided to fix itself? It just worked for some reason after I said something here (well, a few hours later).

Executing a stored procedure from a java program

Hi.. how can i call a oracle stored procedure from a java
program. the OSP has four IN parameters and one OUT parameter(a
cursor). when i try this way.. i get an error
con = DriverManager.getConnection(url, "stored", "stored");
CallableStatement cs =
con.prepareCall(
"{call stored_proce_1(?,?,?,?,?)}");
cs.registerOutParameter(1, OracleTypes.CURSOR);
cs.setString(2, "14541");
cs.setString(3, "gen");
cs.setInt(4, 0);
cs.setInt(5, 5);
ResultSet rs =cs.getResultSet();
while(rs.next()){
System.out.println(rs);
appreciate ur help.
qs

I'm no expert on this, but I have a similar call where I fetch
an Oracle REF CURSOR from a call to a stored function. If you
fetch the cursor as an Object from your CallableStatement, you
can then cast it to a ResultSet e.g.
mystatement.executeUpdate();
ResultSet rs = (ResultSet) mystatement.getObject(1);
Then you should be able to loop through your ResultSet as usual.
Good luck!

Running curl command from a java program using Runtime.getRuntime.exec

for some reason my curl command does not run when I run it from within my java program and errors out with "https protocol not supported". This same curl command however runs fine from any directory on my red hat linux system.
To debug the problem, I printed my curl command from the java program before calling Runtime.getRuntime.exec command and then used this o/p to run from the command line and it runs fine.
I am not using libcurl or anything else, I am running a simple curl command as a command line utility from inside a Java program.
Any ideas on why this might be happening?

thanks a lot for your response. The reason why I am using curl is because I need to use certificates and keys to gain access to the internal server. So I use curl "<url> --cert <path to the certificate>" --key "<path to the key>". If you don't mid could you please tell me which version of curl you are using.
I am using 7.15 in my system.
Below is the code which errors out.
public int execCurlCmd(String command)
          String s = null;
          try {
              // run the Unix "ps -ef" command
                 Process p = Runtime.getRuntime().exec(command);
                 BufferedReader stdInput = new BufferedReader(new
                      InputStreamReader(p.getInputStream()));
                 BufferedReader stdError = new BufferedReader(new
                      InputStreamReader(p.getErrorStream()));
                 // read the output from the command
                 System.out.println("Here is the standard output of the command:\n");
                 while ((s = stdInput.readLine()) != null) {
                     System.out.println(s);
                 // read any errors from the attempted command
                 System.out.println("Here is the standard error of the command (if any):\n");
                 while ((s = stdError.readLine()) != null) {
                     System.out.println(s);
                 return(0);
             catch (IOException e) {
                 System.out.println("exception happened - here's what I know: ");
                 e.printStackTrace();

How to have an Oracle procedure send and receive value from a java program.

The below procedure is place inside a package. This procedure "get_extract_ready_headers " is selecting columns store_number, terminal_number, tran_number, tran_date, cust_id from the source REX_HEAD_EXTRACT table. This information is selected into a ref cursor. The data has cust_id field which is encrypted. How do I modify the procedure get_extract_ready_headers and accomplish 2 things?
1. Make this procedure to read the "cust_id" value from the source table and send the value to a Java program "getheaderinfo" (this java program decrypts the cust_id field).
2. When we get the unencrypted value back from the Java program, make the procedure accept this decrypted value and use it to update CUST_ID value in the target table TRAN_HEAD table. I am using Oracle 11.2.0.2, and TOAD 10.5.1.3.

Assuming that SomeJavePgm is a Java stored function (not a Java program running outside the database) and that it takes as a parameter whatever data type CUST_ID is in TABLE_A (hopefully RAW but potentially VARCHAR2) and returns a string, you would call it just as you would a PL/SQL stored function
INSERT INTO table_b( cust_id, <<other columns>> )
SELECT SomeJavaPgm( a.cust_id ), <<other columns>>
    FROM table_a aIf SomeJavePgm is not a Java stored procedure, calling it from PL/SQL becomes much more complicated. You would need whatever machine hosts this program to expose an appropriate API (for example, a web service interface) that you could invoke via UTL_HTTP). You'd need to tell us what that API was, however.

How to run a cygwin.bat from a java program?

Can you please let me know how to run a cygwin.bat file from a java program and to give commands through java program.

Can you please let me know how to run a cygwin.bat
file from a java program and to give commands through
java program. I have a program to run .exe files, but
when I do the same for the cygwin.bat it doesnt work.Of course not. .bat files are no native executables. You need to open a shell first, like "cmd /c cygwin.bat ..."
& bit urgent. Thanks in advance!If I had read this earlier I wouldn't have replied. Why exactly is your time worth more than anybody else's?

How to read files on server from a java program?

Hello,
I am fairly new to JSP programming. I have an issue with reading files. I am trying to call method of a normal java file from a jsp program. The method I am trying to call does some IO operation on Files. I have the files in the same directory as my class files on server that is in WEB-INF/classes folder. In my java program, I am giving just the file name to open because the files and the classes are in the same directory. But this is not working.
What exactly should I do to read a file from a java program, that is running on the server?
Any help is appreciated.
Thanks,
Krishna

String realFilePath = application.getRealPath("/WEB-INF/myFile.txt");
File fileToOpen = new File(realFilePath);
out.println(fileToOpen.getAbsolutePath() + ": exists? " + fileToOpen.exists());in this case "application" is a reference to the ServletContext.
It is an implicit variable in a JSP. In a servlet:
ServletContext application = getServletConfig().getServletContext();

Calling servlet from a java program

Hi
I need to call a servlet's doPost() method from a java program. I have a specific situation, where I need to call servlet from a java program. DUring this call I need to pass a file and two string to the servlet. Servelt after receiving the file and string uploads the file to the server at a specified location. I am stuck up as how to call servlet from a java program instead of a HTML or JSP.
Can anyone help me to start with this.
any suggestion is welcome.

You have to establish a URLConnection with servlet from your java program.
URL servletURL = new URL("http://localhost:8080/Myservlet?str1=abc&str2=def");
URLConnection servletConnection = servletURL.openConnection();you can get the objectOutputStream
ObjectOutputStream oos = new ObjectOutputStream (servletConnection.getOutputStream());
oos.writeObject(your file object);-------------------------------------------------
In the servlet u can get the strings using request.getParameter("str1");
In the servlet u can get the strings using request.getParameter("str2");
file = new ObjectInputStream (request.getInputStream()).readObject()a lot of resources are available on this ...
hope this helps :)

Cannot call ANY stored functions from my Java program

My problem is that I cannot call ANY stored procedure from my Java
program. Here is the code for one of my stored procedures which runs
very well in PL/SQL:
PL/SQL code:
CREATE OR REPLACE PACKAGE types AS
TYPE cursorType IS REF CURSOR;
END;
CREATE OR REPLACE FUNCTION list_recs (id IN NUMBER)
RETURN types.cursorType IS tracks_cursor types.cursorType;
BEGIN
OPEN tracks_cursor FOR
SELECT * FROM accounts1
WHERE id = row_number;
RETURN tracks_cursor;
END;
variable c refcursor
exec :c := list_recs(11)
SQL> print c
COLUMN1 A1 ROW_NUMBER
rec_11 jacob 11
rec_12 jacob 11
rec_13 jacob 11
rec_14 jacob 11
rec_15 jacob 11
Here is my Java code:
import java.sql.*;
import java.io.*;
import oracle.jdbc.driver.*;
class list_recs
public static void main(String args[]) throws SQLException,
IOException
String query;
CallableStatement cstmt = null;
ResultSet cursor;
// input parameters for the stored function
String user_name = "jacob";
// user name and password
String user = "jnikom";
String pass = "jnikom";
DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
try { Class.forName ("oracle.jdbc.driver.OracleDriver"); }
catch (ClassNotFoundException e)
{ System.out.println("Could not load driver"); }
Connection conn =
DriverManager.getConnection (
"jdbc:oracle:thin:@10.52.0.25:1521:bosdev",user,pass);
try
String sql = "{ ? = call list_recs(?) }";
cstmt = conn.prepareCall(sql);
// Use OracleTypes.CURSOR as the OUT parameter type
cstmt.registerOutParameter(1, OracleTypes.CURSOR);
String id = "11";
cstmt.setInt(2, Integer.parseInt(id));
// Execute the function and get the return object from the call
cstmt.executeQuery();
ResultSet rset = (ResultSet) cstmt.getObject(1);
while (rset.next())
System.out.print(rset.getString(1) + " ");
System.out.print(rset.getString(2) + " ");
System.out.println(rset.getString(3) + " ");
catch (SQLException e)
System.out.println("Could not call stored function");
e.printStackTrace();
return;
finally
cstmt.close();
conn.close();
System.out.println("Stored function was called");
Here is how I run it, using Win2K and Oracle9 on Solaris:
C:\Jacob\Work\Java\Test\Vaultus\Oracle9i\FunctionReturnsResultset>java
list_recs

Any help is greatly appreciated,

Thank you for your suggestion.
I tried it, but got the same result. I think the difference in the syntax is due to the Oracle versus SQL92 standard
conformance. Your statament is the Oracle version and mine is the SQL92. I think both statements are acceptable
by the Oracle.

Compiling Java program from other java program

Hi,
How can I compile and capture the compilation result from another java program?
Thanks

As if I had seen somewhere a hint about being able to
programatically compile with the help of the class
sun/tools/javac/Main found in the tools.jar.I saw that article, too, but when I took a look at the JDK's source code, it became apparent that none of the classes in tools.jar are supported. Your program could break with any new version of the JDK.

Opening a document from a Java app

I need to open a document from my Java app. It is a .rtf file and I would like it to open with the system associated application for rtf files. How should I do that?
I have tried to figure out the Runtime.exec(), but it doesn't do what I need. I have been able to open Notepad or WordPad (oh, yes, I am on a Win XT system) by specifying them in the exec function, but I can't find info on how to let the system choose the program.
Thanks for your help.
