��Java with Matlab??

Hi, I�m new in this group. I try to connect a Java interface with matlab, i use JBuilder and i try to use ActiveX but JBuilder 5.0 don�t support ActiveX. How can i do it?
Excuse me for my bad English.

You could just use the extern part of Matlab to implement an external invocation of the Matlab engine from a C or Fortran program.
Now if you wrap this C implementation in Java through the JNI you would be able to invoke Matlab functions directly from Java.
The other way around is directly supported from Matlab 5.3 and up.

GUI issues with Matlab

Hi,
I noticed that when I invoke matlab code in my EDT of my GUI, it causes the GUI to repaint itself with blank buttons and changes its fonts. In order to resolve this issue, I realize that the matlab code would be the source of the issue and was causing a conflict with the affected java GUI components. Therefore, I invoked the matlab code before I instantiated the GUI. Eventually this led to an interesting out come. All the buttons are not the original default buttons provided by the Java gui framework. Even the text is not the same, the matlab affected text is blue and unbolded, whereas java has them by default bolded and black. What would it be about invoking matlab code that conflicts with java? If by chance this is relevant, I read somewhere that originally Matlab GUI framework is actually based off of java, however I am 90% certain that you can't package GUI applications with Matlab native code, its not supported by the Matlab Compiler Runtime (MCR) Environment. So I don't really understand how it affects it at all. Any ideas?
Thank you.

Hi cpilla17,
This sounds like it could be an issue with MATLAB®. They'll be able to provide more adequate support on their products.
If this is an issue with hardware, you could test out the driver using NI MAX and test panels. If that works, then it's possible that it's not a hardware issue.

Can' t connect Java with MySQL

My goal is to connect Java with MySQL. I found many solutions on Internet, but I always get the same mistake:
SQLException: No suitable driver
SQLState: 08001
VendorError: 0MySQL works fine alone or with php.Only thing left me to think is that the installed versions are not compatible for this mysql-connector-java-5.0.4
I don't believe that could be a reason.
Installed versions are:
Apache Tomcat 5.5.20 Server
Apache HTTP Server 2.2.4
PHP 5.2.0
MySQL 5.2
jre 1.5.0_11
jdk1.5.0_11
Apache Tomacat JK2 connector Version: 1.2.20 File Name: mod_jk-apache-2.2.3.so
mysql-connector-java-5.0.4
I also set connector in class path: C:\mysql-connector-java-5.0.4;C:\mysql-connector-java-5.0.4\mysql-connector-java-5.0.4-bin.jar;C:\mysql-connector-java-5.0.4\src\com\mysql\jdbc
For installation I used manulas from:
http://apacheguide.org/jsp.php
http://doc.51windows.net/mysql/?url=/MySQL/ch23s03.html
Here is also a test code in java:
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
   public class Connect
       public static void main (String[] args)
           Connection conn = null;
           try {
    conn =
       DriverManager.getConnection("jdbc:mysql://localhost/first_test" +
                                   "user=monty&password=greatsqldb");
    // Do something with the Connection
} catch (SQLException ex) {
    // handle any errors
    System.out.println("SQLException: " + ex.getMessage());
    System.out.println("SQLState: " + ex.getSQLState());
    System.out.println("VendorError: " + ex.getErrorCode());
   }i'm desperate, please help or tell me someone who'll know the answer.
Thank You in advance

hey buddy .. it seems yr code is wrong .. in getconnection () method u should also specify the port ,which u r not doing ...
the default port for MySQL is 3306 ... see below i am giving you a sample code ... its working fine .. and dont forget to put the MySQL driver jar path in to classpath and also copy the jar into common/lib folder of your tomcat ....
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
public class MySQLConnectionTest {
     public static void main(String[] args) {
new MySQLConnectionTest().connTest();
public void connTest() {
          String tableName = "portfolio"; //change as per setting
          String hostName = "10.81.9.39"; // please change for the target database ip or hostname
          String dbPort = "3306"; //change if not using the default
          String dbName = "tradingsystem"; //change as per the given DB name
          String username = "root"; //change as per setting
          String password = "password"; //change as per setting
          System.out.println("before try");
          Double data=0.0;
     Double data1=0.0;
          try {
Class.forName("org.gjt.mm.mysql.Driver");
               System.out.println("before driver manager");
Connection conn = DriverManager.getConnection("jdbc:mysql://"+hostName+":"+dbPort+"/"+dbName, username, password);
String query1 = "select * from "+tableName+" where User_id='trader1' and Stock_Type='Equity'";
System.out.println("quesry1="+query1);
Statement stmt = conn.createStatement();
ResultSet rs1 = stmt.executeQuery(query1);
while(rs1.next())
     System.out.println("hiiiiii for rs1");
     System.out.println(rs1);
     Quantity=(Integer)rs1.getObject(5);
     MarketPrice=(Double) rs1.getObject(8);
     data=Quantity*MarketPrice;
     data1+=data;
     System.out.println("data1="+data1);
     i=0;
rs1.close();
stmt.close();
conn.close();
} catch (ClassNotFoundException e) {
e.printStackTrace(System.err);
} catch (SQLException e) {
e.printStackTrace(System.err);
i hope it will work for u...

How to use Java with PL/SQL commands to send an email with attachment

Apologizes in advance if this is the wrong place to ask the question.
I need to use Java with PL/SQL commands to send an email with attachment. My java application runs from the command line and does some magic to gather info from an Oracle 11g db. If the DB has sendmail configured, I'd like to send the results of the data gathering as an attachment to the email addresses. I'm not sure how to do this. I've been reading up on on PL/SQL can send email with UTL_SMTP - with attachments. I'm just not sure how to translate that into being triggered by my Java application. Any suggestions or pointers on what I should read would be appreciated.
Background - I've been programming in Java for 10+ years, but this is my first time using databases. I also have been on these forums for a long time, but lost my profile when it was switched to Oracle.
Thanks for all help.

user13726880 wrote:
The original requirements were put together and given to me, an Oracle newbie. They expected the Java app to use something intrinsic to Oracle and Unix sendmail. To solve my problem, I use a JDBC connection to run some SQL commands. I take that data, format it and send the results by email to the user. By default the requirement is to send it as an HTML attachment using Unix 'sendmail'. So I do that using Runtime exec. I have also added JavaMail functionality as an alternative to sendmail. It works great and as expected.Sounds like a reasonable solution.
Note however that PL/SQL itself can send email. And PL/SQL can call unix sendmail too.
However myself I would have done it in java with JavaMail.

JAVA WITH WINDOWS FORM?

Dear all,
I have a question about java with windows form.
I have an exe or DLL stand alone program make by visual basic 6.
Also I have a java software build up with swing.
Can the exe or DLL program executed inside the Java software?
It means I click the menu and select a function in the Java software.
And then the exe or DLL will be executed and a windows form will be pop up.
But I want to fake like a Java jpanel not a stand alone program run outside the Java software.
Is it possible?
Thanks you~~

All here,
You can do it ... we can hep!
Once you choose the exe you want to run, execute it via Process ... about like so:
          String theWindowsProcess =
                              "notepad.exe";         // OR
//                            "runtc.bat";                // OR
//                            "cmd /C start /min /Dc:\\temp runtc.bat";
          Process myProcess = Runtime.getRuntime().exec( theWindowsProcess);BTW ... this is a very common question.

What contents we can include under JAVA with SAP NetWeaver 7.0?

hi friends,
i want to know about JAVA with SAP NetWeaver 7.0.
whether it covers only java programming or java-WebDynpro,portal and many more?
can somebody give details on this?
i have worked on java-WebDynpro,portal.is that enough to get certification on JAVA with SAP NetWeaver 7.0-Associate C_JAVA_70?
please provide me details.
thanks
Nutan.

Hi Rajesh,
I cleared this certification last year. Go through the syllabus mentioned. In our time there were 13 different sections e.g NWDI, EJBs, WD etc which had multiple choice qs and u need to click on the radio button for that.
How to prepare.
Go through the topics and course books mentioned in the syllabus well. U should be clear with all the basics especially EJBs and NWDI, lot many qs asked from these. WedDynpro qs are basically easy.if u dnt have books chk sdn and help site fot the topics.Qs chk your understanding of the content. They come from syllabus but are not direct and multiple choice make it difficult to answer.
How to answer the questions.
Chk every option in case of mutiple choice. Mark only those options which u are full confident and den if more than 50% confident bcoz we heard there were -ve markings although not sure how they calculated marks.
Is any sample test program is there?
There are no sample test program for this.
All D Best for the certification.

Priyanka

Accessing BAPI's using JAVA with out using webdynpro URGENT

hi Experts,
What is the procedure for calling RFC/BAPI's using JAVA with out using the webdynpro. Please let me know what are the possibilities with step by step implementation.
Regards
Vijay

Hi Boris Rubarth,
Thaks for relavant information.
I have kind of the requirement. The clinet is asking for connecting the SAP RFC using java application. The build Jar or .war or .Ear for which are going to develop should be compatible for running on any of the Applications server like they have Tom cat, weblogic, websphere server.
so the .jar for or .ear file which we are going to develop should be able to run accessing the RFC/ BAPIs from any of these servers other than SAP WAS that is what their target.
Please give me your suggestion, which is better approach. currently their SAP system is 4.6c . So presently it is not possible the webservice approach. But they have plans to go for upgrade to ECC6.0
In that case only JCO option is possible. If use this option . Is it possible to access application which is deployed irrespective of the WAS by doing the required configuration.
Basically i am aware of the ABAP webservice work bech steps and also the JAVA coding also.
Please suggest me what is the better way to achieve this.
Regards

Thanks For Reading
Thanks a lot in Advance For your ANSWERS

maybe if you asked nicely instead of ordering people around we might tell you.
As it is all you're going to hear is that you don't need both those jars, as they contain different versions of the same driver.
I'm not going to tell you which you need, as you should have the documentation to tell you that. But then you also should have the documentation to tell you how to set your classpath properly and you failed to read that too.
