Problems in SQL Connection from Java program to Oracle 8.1.7

Hi,
I am java program that connects to Oracle 8.1.7 .
Client: java code on Windows 2000
Server: oracle 8.1.7 on Solaris
Java code uses two types of Connection Pools. One Pool uses "thin" connections and other pool uses "OracleConnectionPoolDataSource" class.
The methods which use "thin" pool work great however the methods which use "OracleConnectionPoolDataSource" fail after 5 to 10 calls.
Given below is the exception that I see in my log file.
February 26, 2002 10:17:38 AM UTC: Debug.INFO: searchByNameCommono.jsp Error : Tpd2.openConnection(1)failed:DBConnPool2.getConnection(String) failed:Closed Connection
com.commerceone.msbtpdapi.util.DBConnException: Tpd2.openConnection(1)failed:DBConnPool2.getConnection(String) failed:Closed Connection
at com.commerceone.msbtpdapi.api.Tpd2.openConnection(Tpd2.java:138)
at com.commerceone.msbtpdapi.api.TpdDBApi.searchTpsByCompanynameAndStatus(TpdDBApi.java:1685)
Windows java code uses JDK 1.3.1
Oracle machine has java version 1.2.2.
Do I need to check for any settings like LD_LIBRARY_PATH on oracle machine ?
Thanks a lot.

Calling oracle SQL Loader from java program

Hi,
I want to insert data into oracle tables from a text files containing fixed length fields. I am using SQLLoader to achieve this. The requirement is to call the SQLLoader within the java program.
Does anyone know how to call SQL Loader from java program?
Thanks,
Varsha

Simply "exec" the sqlldr program with the parameters you need to pass to it.
Runtime.exec (........)
Try to pass all parameters needed including the username and password, and use the option "silent" to avoid output, and the option "log" to have a log file of the modifications that sqlldr has done to the database.

Run dial-up connection from Java Program?

Is there a way to run dial-up connection from a Java Program? It needs to platform independent.
Thanks.
Virum

I very much doubt it, at least not platform independent. I had a, oops, heck of a time doing that from Visual Basic, where it is much easier to work with operating-system stuff like that than it is in Java. I finally ended up buying a RAS component to call from my VB program.

Calling SQL LOADER From Java Program

Any Pointers in this regards will be really appreciated.
Thanks

You can create two different files which has sqlldr command defined....
1. loader.sh
2. loader.bat
and in the depending on the OS execute one...
         String command = "";
         if(System.getProperty("os.name").equals("Windows 2000")){
                //if os is windows 2000 then execute bat file
                 command = <<bat file path>>
          }else{
                  command = <<shell path>>
          Runtime rt = Runtime.getRuntime();
          Process p = rt.exec(command);
          int i = p.exitValue();

Hi , I dont know if u got the answer but couple of things i wanted to let u know.
1. the driver u r using make it a thin driver as u r specifying that in the url .
http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/htdocs/winsoft.html
loading class 'oracle.jdbc.driver.OracleDriver'
and url u have to change a little, this depends on the driver u use.

Connect to MS Sql Server from Java Source

Hi,
Is there any way I could connect to ms sql server from Java source? I know I can call java source from function thats easy but what I really want is capability to connect to non-oracle(MS SQL server) from my java source and then call it from function.
I don't know if JDBC driver for SQL server is even installed/available. Is there a way I could find it out form my IDE? I know sqlJ does compile but I have never used sqlj. help!!!

You'll probably have better luck in a Java forum or a Microsoft forum.

Problem while running dos command from java program

Dear friends,
I need to terminate a running jar file from my java program which is running in the windows os.
For that i have an dos command to find process id of java program and kill by using tskill command.
Command to find process id is,
wmic /output:ProcessList.txt process where "name='java.exe'" get commandline,processid
This command gives the ProcessList.txt file and it contains the processid. I have to read this file to find the processid.
when i execute this command in dos prompt, it gives the processid in the ProcessList.txt file. But when i execute the same command in java program it keeps running mode only.
Code to run this command is,
public class KillProcess {
     public static void main(String args[]) {
          KillProcess kProcess = new KillProcess();
          kProcess.getRunningProcess();
          kProcess = new KillProcess();
          kProcess.readProcessFile();
     public void getRunningProcess() {
          String cmd = "wmic /output:ProcessList.txt process where \"name='java.exe'\" get commandline,processid";
          try {
               Runtime run = Runtime.getRuntime();
               Process process = run.exec(cmd);
               int i = process.waitFor();
               String s = null;
               if(i==0) {
                    BufferedReader stdInput = new BufferedReader(new
                           InputStreamReader(process.getInputStream()));
                    while ((s = stdInput.readLine()) != null) {
                     System.out.println("--> "+s);
               } else {
                    BufferedReader stdError = new BufferedReader(new
                           InputStreamReader(process.getErrorStream()));
                    while ((s = stdError.readLine()) != null) {
                     System.out.println("====> "+ s);
               System.out.println("Running process End....");
          } catch(Exception e) {
               e.printStackTrace();
     public String readProcessFile() {
          System.out.println("Read Process File...");
          File file = null;
          FileInputStream fis = null;
          BufferedReader br = null;
          String pixieLoc = "";
          try {
               file = new File("ProcessList.txt");
               if (file.exists() && file.length() > 0) {
                    fis = new FileInputStream(file);
                    br = new BufferedReader(new InputStreamReader(fis, "UTF-16"));
                    String line;
                    while((line = br.readLine()) != null) {
                         System.out.println(line);
               } else {
                    System.out.println("No such file");
          } catch (Exception e) {
               e.printStackTrace();
          return pixieLoc;
}     when i remove the process.waitFor(), then while reading the ProcessList.txt file, it says "No such file".
if i give process.waitFor(), then it's in running mode and program is not completed.
Colud anyone please tell me how to handle this situation?
or Is there anyother way to kill the one running process in windows from java program?
Thanks in advance,

If i open the file when program in running mode, no contents in that file.
If i terminte the program and if i open the file, then i find the processid in that file.
Can you help me to solve this issue?

MySQL trying to connect my java program

I am trying to write a java program that I can connect to a MySQL database on my compter. I have typed out this example that is in a text book I have and I am trying to connect my java program to a MySQL database. The version of MySQL is 4.1 which I have recently downloaded onto my computer and is working fine. The problem I am having is in ther places where it says "WHAT DO I ENTER HERE", basically the 'database.properties' , the 'jdbc.drivers' and the 'jdbc.url' string names. I do not know what I am supposed to enter. If you could give me some help with what I am supposed to enter or an example of a java program that already works with MySQL that would be of great help to me. A working example would be the greatest help to me .
Thank-you.

CREATE OR REPLACE FUNCTION EXPORT_HIST_ALARMS_FUNC(startDateTime VARCHAR2, endDateTime VARCHAR2, meType VARCHAR2) RETURN VARCHAR2 IS
END EXPORT_HIST_ALARMS_FUNC;
Above function I have called following way in java.
String sql = "begin ?:= EXPORT_HIST_ALARMS_FUNC(?, ?, ?); end;" ;
CallableStatement cStatement = null;
cStatement = connection.prepareCall(sql);
cStatement.registerOutParameter(1,Types.VARCHAR);
cStatement.setString(2,startDateTime);
cStatement.setString(3,endDateTime);
cStatement.setString(4,meType);
cStatement.execute();
msg = cStatement.getString(1);
Actually above function requires three input parameters and one return parameter.
During execution of above java code it throws SQLException and shows PLS-00306: wrong number or types of arguments in call to 'EXPORT_HIST_ALARMS_FUNC' error.
I have run this function directly from oracle with three parameters and run successfully and finally it returns string.
But I am unable to figure out why it doesn't run from above java code.
Please help regarding this.
Thanks.
Regards,
Shardul Banker

Try this:
String sql = "begin ?:= EXPORT_HIST_ALARMS_FUNC(?, ?, ?); end;" ;
CallableStatement cStatement = null;
cStatement = connection.prepareCall(sql);
cStatement.registerOutParameter(1,Types.VARCHAR);
cStatement.setString(1,startDateTime);
cStatement.setString(2,endDateTime);
cStatement.setString(3,meType);
cStatement.execute();
msg = cStatement.getString(1);Regards,

Hi,
the JavaAPI didn't work with the xdo-Files. But you can create a proxy stub for the Web Service API of BI Publisher which uses the xdo's in the repository.

Problem wtih JDBC Connecting in jsf program.

Hey guys. I have a web app setup thanks to some of you guys on here. I'm using mysql jdbc access for login. I'm using the connection pool and resource for connectivity.
Basically what I'm asking is can I use to DataSource variables on the same page. The reason I'm asking that is. I can connect fine with the login code.

}Ok now I have some separate code that access the same database but fills a table on the same login.jspx page.
package page;

import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.logging.Level;

public class LineStatus {
    @Resource(name = "jdbc/must2")
    private DataSource ds;
    private ArrayList line = new ArrayList();
    public LineStatus() {
        try {
            GetLineStatus();
        } catch (SQLException ex) {
            Logger.getLogger(LineStatus.class.getName()).log(Level.SEVERE, null, ex);
    public void GetLineStatus() throws SQLException {
        if (ds == null) {
            throw new SQLException("No data source");
        Connection conn = ds.getConnection();
        if (conn == null) {
            throw new SQLException("No connection");
        try {
            PreparedStatement passwordQuery = conn.prepareStatement("SELECT DISTINCT pkg_line_id,shortname, " +
                    "line_status FROM pkg_line_tree LEFT JOIN pkg_line using (pkg_line_id) " +
                    "WHERE tree_id = ? ORDER by shortname");
            passwordQuery.setInt(1, 3075);
            System.out.println(passwordQuery);
            ResultSet result = passwordQuery.executeQuery();
            while (result.next()) {
                line.add(new Line(58285, "Line 1", "Test", 43500, 21695));
        } finally {
            conn.close();
    public ArrayList getLine() {
        return line;
}There is nothing wrong with the code. I checked it over and over. Even replaced this code with my same login code that works. Every time I run the page I get "no data source". Obviously becasue Datasource is null. I have setup to catch the error. I'm guessing that the two backing beans can't access the same data base on the same page. I'm not sure though. I need to figure out how to get around this. Thanks for any help guys.

Anybody know? I've tried everything I can think of.

SOLVED: How To Use LDAP over SSL (no certs) from java program

Trying to connect to OID from Java program (using Grocery Store demo as a test). Want to use SSL with no server certificate. OID is configured, and ldapsearch -U 1 works.
Tried using URL with ldaps, or adding SECURITY_PROTOCOL,"ssl". In both case the error is 'simple bind failed'.
Samples on OTN say this should be possible, but then only have code for the non-ssl connection.
Posting from others with this same question don't seem to have been answered.

I have found that using ConnectionUtil.getSSLDirCtx() from Oracle will make a no-authentication SSL connection. An example in the sample code would be useful.

Even with Java APIs, There is a way to talk through SSL without bothering about certificates. It's just that you will have to write some code and make some changes in settings.
Read following to get further information on the same.

I don't know or I won't comment whether it's the right approach or not but it's definitely a work around.
Thanking You
