Sun Jdbc and j++, Help!!!

Hello,
I'm trying to use the Sun Jdbc-Odbc bridge with MS J++.
if I import the rt.jar file to the classpath of my project in j++, as I run or debug the project, I get the following error message: "Unable to locate system class: java/lang/String"
How do I use the sun Jdbc-Odbc bridge, on the MS - J++
environment?
so far I managed to work with JBuilder, but I have a slow computer, and J++ is my only solution.
thanks in advance....

Hi,
J++ has its own VM. You cannot add the runtime classes from another VM because this will cause incompatibilities between them.
There are other IDE's that are faster then JBuilder (like RealJ or JCreator). Perhaps you can use one of those.
I think there is also a jdbc-odbc bridge delivered with J++, but I can't remember its exact class name. I don't recommend using it since MS doesn't support J++ anymore.

Help on RFC to JDBC and JDBC to RFC

Help on RFC to JDBC and JDBC to RFC
Hi Gurus
I have the scenario where an RFC will be triggered in SAP , to write to a DB2 database and insert new records in a table
and vice versa the JDBC has to read som data from a table based on a primary key, mark them as read for not be read next time and send the data to an RFC where a table in SAP will be updated.
I have never worked with JDBC before , pls advice.
is there any new issue to consider in PI 7.0 regarding JDBC
Thanks.

The requirement looks standard,
SEARCH IN SDN FOR JDBC scenarios,you will find many docs for sender as well as Receiver.

Problem with JDBC and Tomcat

I don't know where the problem originate, the only thing in my memory is that the program worked very well on my PC yesterday, but today, without even slightest change, it doesn't work anymore. As to debug it, I simplified the codes to the least, but it still refuse to work. I was beaten down by this problem totally, and cannot make out any solution for it, so, I come here, hoping to find a warrior to kill this damned bug for me.
My program is a Servlet, but for the purpose of debugging, I have recode it to an Application/Servlet. When run as a application, I can get the result expected, but as a Servlet, :-(, maybe you should see it by yourself. My server software is Tomcat 4.1.15, and the JDK version is 1.4.0. To excute this program, you should add Data Source "Test" to ODBC.
///////////////////////code begins/////////////////////////
import java.sql.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;
public class Ex extends HttpServlet
 int ErrorType = 0;
 String err = new String("");
 public static void main(String args[]) throws Exception{
 Ex cEx = new Ex();
 cEx.init();
 System.out.println(cEx.ErrorType);
 public void init() {
 String url = "jdbc:odbc:Test";
 ErrorType = 3; //passed
 try{
 Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
 } catch (ClassNotFoundException e) {
 e.printStackTrace();
 ErrorType = 1; //trapped in Class.forName
 try{
 Connection c = DriverManager.getConnection(url);
 } catch (SQLException e) {
 e.printStackTrace();
 ErrorType = 2; //trapped in DriverManager.getConnection
 err = e.getMessage();
 public void service(HttpServletRequest req, HttpServletResponse res)
 throws IOException {
 res.setContentType("text/html; charset=GB2312");
 PrintWriter out = res.getWriter();
 out.println("Success " + "" + ErrorType + "" +err);
 out.close();
//////////////////////////code ends///////////////////////////////
The result from the Servlet tell me that the problem occurred within the connection process, I don't know who should be responsible to this - Tomcat or JDBC?

If you could print the exception that you got then that would help :) In the mean time, I could make a guess. It is unlikely that your application server (in this case, Tomcat) is blocking connections from your servlet. So the problem is either with JDBC directly or with the underlying datasource. It seems unlikely that it is JDBC given that you have stated that the code has not changed and it works in application form.
My guess would be that you are coming up against some sort of security constraint (eg: your DBMS is letting you log in from one IP but not another?, your Java plug-in security policy is disallowing the connection?). It's hard to say.
But if it works as an application but not via a servlet then you could try putting this in your java.policy file, which is located in the directory where your plug-ins are installed (eg: "C:\Program Files\Java\<version>\lib\security\") on Windows systems;
permission java.net.SocketPermission "bend xp:1099", "listen,connect,accept";
Try that, see if it works :)

IDoc to JDBC and JDBC to IDoc Scenario

Dear All,
I am working on IDoc to JDBC and JDBC to IDoc Scenario.
I have to send Idoc from SAP to Non SAP system(.NET application) i almost configured in XI but still i don't know when my INTEGRATION will INVOKE how my data will proceed from IDOC to Oracle database(Through JDBC) and in case of revese how and when Data flow will start.
Does anyone have completed STEP by STEP scenario document for this?
How my Idoc will sent to XI?
How XI will pick up data from IDoc?
How XI will Convert data to JDBC and UPDATE in Oracle Database?
And i reverse case(JDBC to IDoc) when my INTEGRATION will INVOKE?
Where and When i can watch my process and data?
How can i test the whole integration?
I AM GETTING ERROR WHILE TESTING CONFIGURATION IN Integration Directory "Error while refreshing the XI runtime cache" and when i check this in SXI_CACHE it gives me error
"Unable to refresh cache "NO_BUSINESS_SYSTEM"
"Error during last refresh to cache"LCR_GET_OWN_BUSINESS_SYSTEM - NO_BUSINESS_SYSTEM"
Please solve all the above problems i will reward u points

Problem using JDBC and MS SQL Server

I got a problem trying to acces a database on my SQL Server. I created the table and my connection seems ok, but when i try to get some data from a table, this happens (see below).
java.sql.SQLException: [Microsoft][ODBC SQL Server Driver][SQL Server]Invalid object name 'players'.

here's the code that i used to access the db with:
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection conn = DriverManager.getConnection
("jdbc:odbc:BRAIN2WINXPPJH","sm","sm");
Statement stm = conn.createStatement();
String query = "Select * from players where teamnr = " + nr +
" order by squadnr";
ResultSet rs = stm.executeQuery(query);
any help is more than welcome
tnx
Jo

If all the tables are in the same database, you can use
Connection.setCatalog("db-name")
to change the current database. But the suggestion to include the database name in the SQL statement is safer, because you do not need to worry about changing the database at the right point.

JDBC virgin needs help.

Hi, I am a 2nd year university student doing JDBC for the first time.
I think my problem lies in the ODBC data sources rather than the code since the code works on the machine in university (NT) but not on my home PC (XP). When I run the code I get no errors but nothing happens in terms of interrogating or writing to the database (Access).
I have tried a crude debug by performing a System.out.print at various stages and the result is that the message will display before I implement executeUpdate but not after. Any wise tips on how to ensure that my database is set up and working properly in XP? (I am sure this is the root of the problem rather than the code <supplied here anyway>)

Sun.jdbc.JdbcOdbcDriver ClassNotFoundException

I'm not really a java expert, but as far as I know you have to install the jdbc-driver and to add the path to the driver to CLASSPATH-variable.
If that doesn't help, you shoul post you question in a java forum, e.g. this one:

Tomcat, JDBC and other APIs

Hi all,
This must be one of the most trivial questions to ask, but I'm new, so please bear with me.
I have downloaded Tomcat, JDBC and JSSE. The question is: in which directory should I unpack these files and how should I set them up so that my Java compiler (JAVAC) will recognize this change?
I am using the Java Software Development Kit version 1.3, and all of the class files, compilers and sample code that came with the SDK are in C:\jdk1.3.0_02\.
Thank you in advance,
cindybubbles

Hi there,
There's not much to installing Tomcat other than unzipping the distribution file, moving it to the place where you want it to be in your filesystem and then following the installation instructions in the Tomcat User's guide. This involves setting the TOMCAT_HOME and JAVA_HOME environment variables. Once you've set JAVA_HOME then Tomact can now find your Java installation.
The core JDBC package is included in jdk1.3.0_02, if it's the optional package that have then just install it's jar file in c:\jdk1.3.0_02\jre\lib\ext
JSSE also can be installed as a standard extension so copy it's jar file to c:\jdk1.3.0_02\jre\lib\ext.
When a jar file is added to c:\jdk1.3.0_02\jre\lib\ext, the classes and packages that it contains will be available to you and to other applications that use the jdk (such as Tomcat). The term Standard Extension has been replaced with "Optional Package" now, but you are likely to still see both terms used interchangeably.
Hope this helps.

How can i put a file into blob(using sun.jdbc.odbc.JdbcOdbcDriver)

Hi
i tried to put a file into blob , but got a problem.....
My environment:windows 2000pro,JBuilder 5.0 enterprise,oracle 8.1.6,(not install oracle jdbc driver )
a part of program(my program is very uglily,if anyone want,later i paste it ba....~_~)
//Statement stmt2=null;
//Resultset rs2;
//opa1 is the blob data
void saveBlobTableToDisk(Connection con) {
try {
stmt2=con.createStatement();
sqlStr2="SELECT * FROM emp3 where id=1004";
rs2=stmt2.executeQuery(sqlStr2);
while (rs2.next()) {
Blob aBlob=rs2.getBlob("opa1");
i got the exception :
" null
java.lang.UnsupportedOperationException
 at sun.jdbc.odbc.JdbcOdbcResultSet.getBlob(JdbcOdbcResultSet.java:4174)
 at test3.Frame1.saveBlobTableToDisk(Frame1.java:48)
 at test3.Frame1.<init>(Frame1.java:26)
 at test3.Application1.<init>(Application1.java:5)
 at test3.Application1.main(Application1.java:8) "
and the windows pop up a messagebox said that(about) my memory "0x09af007f" could not read, error in javaw.exe .
Later i used (ResultSet)getBinaryStream() to solve it. but getBinaryStream() only return a InputStream,so that i can make blob to a file,but i can't make a file to blob using jdbc.....
I am very stupid that installing sun java, oracle jdbc driver etc....(because i must set a lot of thing such as classpath,java_home etc), Can i only use JBuilder to do that ?
Or i must install oracle jdbc driver ?
Thanks.

My guess here is that Sun's JDBC-ODBC bridge doesn't handle the BLOB datatype. Most ODBC drivers don't support that datatype, so I wouldn't expect the bridge to.
Is there a reason that you can't use the Oracle driver?
