Java Database Interfacing

Hi all,
Im relatively new to java programming and have come from a PHP base of programming with mySQL, and was wondering what is the best way for me to get into database interfacing with java. Anybody know any good tutorials for me to try, also what is the best kind of database to use with java and why? Just doing a little research before i start to go all out learning one particular way. I would like to program java to interface with mySQL in the same way that PHP does, if anyone can enlighten me I would appreciate that..
-Tom

Ok i have done that now, I got postgresql and it now
appears in the runtime databases section, how do i
create a database with it because it seems to want
the database URL in the following format:
jdbc:postgresql://<HOST>:<PORT>/<DB> . All i want to
know now is how to create a database to use That will be desribed in the docs provided by the vendor.
and how
what i would write in this field?Replace <HOST> with the name or IP address of the host where the DB is. Most likely localhost
<PORT> can probably be skipped, sinc you'll probably be using the default port.
<DB> is whatever you name the database you create.

Problems with Java AQ interface migrating 9i to 10g

Hi!
I've got problems with Java AQ Interface migrating from 9i DB, JDBC, AQ to 10g rel.2 DB, JDBC, AQ
First, i started to occasionally receive NullPointerException in Oracle JDBC 9.2.0.8
java.lang.NullPointerException

We were using 9.2.0.8 JDBC and 9i and 10g databases.
We decided to go up for 10g r2 JDBC Drivers, and 10.2 AQ but started to get the following errors:

I'm specifying address of an agent, but oracle says I am not.
I tried both native AQ and JMS interfaces, bot got the same error. I specify recipient the following way:

Help Error in RSQL module of database interface

I have my RFC using OO.
I can excute it in the ECC System, but when i using java to call the function , the error 'Error in RSQL module of database interface' return.
I don't know why? If any help, that will be great.
in SM21 , there is it:

I just found that in RFC, the data element should not be the domain. but must be the data element, or called data type.
Change field data element, it will be ok
Hope it is helpful.

Login codes using java database (validates with Microsoft Access File)

hi all pro-programmer, can you show me the code to login with the username and password using java database. When the user enters the username and password in the login page then it will go to the requested page. may i know how to do it?

no one will give you complete code.
i'll lay out the pieces for you, though:
(1) start with a User object. give it username and password attributes.
(2) write a UserDAO interface with CRUD operations for a User object.
(3) write a UserDAOImpl for your Microsoft Access database
(4) write an AuthenticationService interface
(5) write an implementation of the AuthenicationService that works with the UserDAO to authorize a User.
Use a servlet to accept request from your login page and pass it off to the service. Voila.
PS - Here's skeleton to start with. UI, servlet, and controller are your responsibility:
package model;
public class User implements Serializable
    private String username;
    private String password;
    public User(String u, String p)
        this.username = u;
        this.password = p;
    public String getUsername() { return username; }
    public String getPassword() { return password; }
public interface UserDAO
    public User findByUsername(String username);
    public void saveOrUpdate(User user);
    public void delete(User user);
public class UserDAOImpl implements UserDAO
    private Connection connection;
    public UserDAOImpl(Connection connection)
        this.connection = connection;
    public User findByUsername(String username)
        String password = "";
        // logic for querying the database for a User
        return new User(username, password);
    public void saveOrUpdate(User user)
        // save or update a User
    public void delete(User user)
        // delete a User
public interface AuthenticationService
    public boolean isAuthorized(String username);
public class AuthenticationServiceImpl implements AuthenticationService
    private UserDAO userDAO;
    public AuthenticationServiceImpl()
        // Create a database connection here and the UserDAO, too.
    public boolean isAuthorized(String username)
        boolean isAuthorized = false;
        // Add logic to do the database query and decide if the username is authorized
        return isAuthorized;
}

Error in module RSQL of the database interface.

Hi Expert,
I get this error "Error in module RSQL of the database interface." when the below ABAP statement executed, do you know the root cuase? Thanks.
ABAP Code:
data lt_fact type TABLE OF /BIC/FZRT_C002.
data ls_Fact type /BIC/FZRT_C002.
*SELECT * INTO table lt_fact FROM /BIC/FZRT_C002 WHERE KEY_ZRT_C0021 in lt_RSDIMID and KEY_ZRT_C0022 in lt_caRSDIMID*.
Information in ST22.
What happened?
    Error in the ABAP Application Program
    The current ABAP program "SAPLZZ_FG" had to be terminated because it has
    come across a statement that unfortunately cannot be executed.
Error analysis
    An exception occurred that is explained in detail below.
    The exception, which is assigned to class 'CX_SY_OPEN_SQL_DB', was not caught
     in
    procedure "ZCA_GET_CUBE_STOCK" "(FUNCTION)", nor was it propagated by a RAISING
     clause.
    Since the caller of the procedure could not have anticipated that the
    exception would occur, the current program is terminated.
    The reason for the exception is:
    The SQL statement generated from the SAP Open SQL statement violates a
    restriction imposed by the underlying database system of the ABAP
    system.
    Possible error causes:
     o The maximum size of an SQL statement was exceeded.
     o The statement contains too many input variables.
     o The input data requires more space than is available.
     o ...
    You can generally find details in the system log (SM21) and in the
    developer trace of the relevant work process (ST11).
    In the case of an error, current restrictions are frequently displayed
    in the developer trace.

Possible errors:
o The maximum size of an SQL statement has been exceeded.
      o The statement contains too many input variables.

RFC_ERROR_SYSTEM_FAILURE: Error in module RSQL of the database interface

HI All,
I am trying to execute an RFC through JCO connection and getting the error "RFC_ERROR_SYSTEM_FAILURE: Error in module RSQL of the database interface".
While debugging I have found that the actual cause of dump is a SQL command written in this RFC. The SQL command is
SELECT DISTINCT *
 INTO CORRESPONDING FIELDS OF TABLE lt_calcrule_hol
 FROM itc_calcrule_hol
 FOR ALL ENTRIES IN calc_rule
 WHERE rule_id = calc_rule-rule_id
 AND start_date <= sy-datum
 AND end_date >= sy-datum
 AND (lv_ident)
 AND ( (lv_orgs)
 OR location_type = '' ).
Here the value of lv_ident is ======>> ident IN ('US','B2'.........................)
and value of lv_orgs is =========>> location_type IN ('S1','S2',..............................)
location_type and ident are columns in table itc_calcrule_hol .
I have analysed that if I pass around 700 enteries in the lv_ident and lv_ogs then it is working fine.
But if I have more than 900 enteries in these variables then it dumps.
Can anybody let me know what is the issue with the query here.And what could be the solution.
Thanks and Regards,
Reena

I'd recommend talking to an experienced basis admin or ABAP developer. First of all it would help to look at the short dump in SAP, to see if that gives any useful information. In case of a generic error like DBIF_RSQL_INVALID_RSQL, the developer trace of the work process (dev_w<n>) should contain further information (to get the number of the work process that handled your RFC call check the system log, which contains the reference along with a comment about the dump). So I'd check those first to see what actually caused the problem.
Information on maximum SQL statement length can either be retrieved from the database vendor's documentation or alternatively by searching SAP [OSS notes|https://service.sap.com/notes]. For the latter you need a valid user ID for the SAP service market place.

Internal error in the database interface (Oracle)

I have recently an Oracle runtime error just by entering the SAP system (SAP ECC 6.0).
DBIF_RSQL_INVALID_REQUEST
The current ABAP/4 program terminated due to
an internal error in the database interface.
Error analysis
An invalid request was made to the SAP database interface in a statement
in which the table "DOKTL " was accessed.
Trigger Location of Runtime Error
Program                                 SAPLSDOC
Include                                 LSDOCU09

I appreciate any helpful information.
Thank you very much indeed
Thom

hi Thom,
most error relating to table DOKTL are caused by misconfigured network card.
if this is a "home" system, install a loopback adapter from Microsoft and use IP address 127.0.0.1 and also check "hosts" file for inconsistency. do not use the IP adddress provided by your ISP as it may change.

What the Enviroment required for java databases programs?

Hi guys
What the enviroment required for java databases programs?
If I have oracle of version 9i and java 1.4.1 platform
do I need Jdeveloper platform ?

What the enviroment required for java databases programs?What do you mean by "environment"?
f I have oracle of version 9i and java 1.4.1 platformYou just need to download Oracle's 9i JDBC driver (ojdbc14.jar) and put that in your CLASSPATH. Then write JDBC code to connect to Oracle and issue SQL commands.
do I need Jdeveloper platform ?No, JDeveloper is an IDE. Not required.
Why Java 1.4.1? We're up to Java 6 now. You're two major versions of the JDK behind.

Re: Java Database

Hello,
I'll like some advice on the topic mentioned above. I'm a beginner of java programming and have elementry knowledge about java. I'll like to know how is it possible to input the list of data in Excel format into Java Database Connectivity and how am I able to extract out the info. that I'll need. Like say the columns/field on designation and name. How am I able to extract the data and change it like to delete or edit the info.??
Pls. explain it step-by-step your patience is really appreciated. Thanks and God Bless.

You should search Javaworld for "Excel" - they've had a few articles about using JDBC to access Excel. As far as I recall, though, you can't alter data in Excel through JDBC, only read it.
http://www.javaworld.com
There are other ways of getting at Excel data through Java but they're not very good either (unless you want to use a Java-COM bridge).

Error in the module RSQL accessing the database interface

I have written the following query.
SELECT a~no
         a~hist_no
         a~chk_stat
         a~chk_date
         a~user as chk_user
         b~name as chk_by
         into corresponding fields of table hist
         from zhist as a INNER JOIN zuser as b on
         auser = bbname
         where pspnr = v_pspnr
         and   chk_no = v_chk_no.
I am getting the dump "Error in the module RSQL accessing the database interface".
Please provide me the solution.
Thanx,
Selva.

Hi,
As i have analysed your query in that you are putting the data in the internal table 'hist' which is also a standard structure and if you check in SE11 'hist' is the standard structure for 'Tablespace History' and might be because of that it is causing the problem.
Kindly check by changing the name of the internal table to tt_hist and then try.
I think that will solve the problem.

Java Application interface with MS Excel through DDE

We have a financial application written in JAVA and have requests from users that want to interface with the application. Meaning, They would like the Java application interface with Excel. For example, if you had a C++ application, you could create a DDE link in Excel that points to the C++ application and receive the data.
How could I do this with a Java Applictaion ? I was told that there was an application written that lets Java interface with Excel.
Any ideas or does anyone know ?
