Problem with JDBC CONNX (make Rollback)
When we work with tables in BD since Oracle ADF through this JDBC ConnX operate correctly, except when done in a transaction rollback, which produces the following error performance: "Statement not active."
To determinate where the error occurred, we have made the following evidence:
- 1st Test (ADF-BC):
We create a project a ADF-BC with a single entity and a single view object based on that entity.
We introduce the View object in an Application Module.
We execute test Application Module, we have modifying a field of view of a row and then we execute Rollback.
In this first case, It produce an exception: "Statement not active."
It occurs the same exception when not change anything, and we do Rollback.
- 2nd Test (with Java J2EE): You make a Java class that does all the above, but with our Java code:
Open a connection with the BD Oracle through ConnX.
We changed the same field in the same row of the same table in the 1st Test, and then we do the Rollback.
In this second case, the RollBack has functioning properly.
Close the connection.
The conclusion of the evidence, is that when we do the 1st Test the RollBack, this Statement is not Active between ADF-BC and JDBC ConnX, but we unknown by that this staments has been closed, and why the project ADF-BC need it.
We have actived to the project ADF-BC the bigger log that we know: Project Properties> Run-Debug> Edit> Options Java-Djbo.debugoutput = console. And we not finish to detect where the error occurs.
We need to see the code that generates ADF-BC for this test and thus be able to trace what is running ADF-BC to the lowest level, to identify the problem and to execute a RollBack correctly.
This is the error Trace:

Hello Frank,
We use:
Sql Flavor: SQL92
Type Map: Java
We've done the test with DataDirect JDBC for Oracle and it works fine. It seems that the
error happens in the function "bindParametersForCollection" which calls the
other two ones you sent us. We think it's in the
freeStatament call, but we'd like to review it.
Thanks in advance.

I have a problem with JDBC Realm in Tomcat/Oracle/Win XP
I have a problem with JDBC Realm in Tomcat.
I have attached my server.xml file located in the
C:\Program Files\Apache Software Foundation\Tomcat 5.5\conf\server.xml
The Problem is that when I login I get the user name and password prompt but it does not resolve.
When I enter in the tomcat-users.xml password with memory realm uncommented it works fine.
C:\Program Files\Apache Software Foundation\Tomcat 5.5\conf\tomcat-users.xml
Is there a cache or something I need to reset for the JDBC Realm to work?
I have attached my tables and contents as well...
Did I miss something????
Thanks
Phil

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.*;

String err = new String("");

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 :)
Ben -
Hi, sorry but in other forum nobody answer my question.
the probles is using JDBC 2.0, my cod is:
Statement c = conn.createStatement();
Statement =conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE);
ResultSet rest = n.executeQuery("select * from t_prueba");
rest.last();
rest.updateBlob("C", null);
rest.updateRow();
rest.close();c.close();conn.close();
at time to execute this code, i have this error:
java.sql.SQLException: Operaci�n no v�lida para el juego de resultados de s�lo lectura: updateBlob

why is this problem if i using ResultSet.CONCUR_UPDATABLE in my statement.
i 'm using jdeveloper 10.1.2 whith j2se 1.4.2_04
please anyone can help me please

alexThere are numerous problems with what you posted.
1) Do you mean to use updateNull and not what you are doing?
2) As mentioned why would you not do this in an UPDATE query? Even if you get this to work arbitrary moving around in a result set that you don't even need along with bad practices like SELECT * is just bad all around.
3) Further as mentioned what you are trying to do is not supported (obviously) by your driver/database etc. Just because you ASK for a scrollable updatable cursor does not mean that you get one. You ask for one but obviously that error message says that the cursor is read only. For the benefits of others it says (more or less) "invalid operation on read only result set : updateBlob"
Possibly you will have to use a forward only cursor to make it updateable... I don't know consult the Oracle docs. Or better yet don't do it this way. -
I'm having problems registering jdbc drivers. I've been trying to register the microsoft Sql Server 2000 jdbc driver so that I can create a connection in my code rather than using entity beans. I've set the CLASSPATH variable to point to the driver's .jar files in the install directory with no success.
I've connected to the database using the driver via the IDE' s Runtime and it tests ok and allows me to create a database schema ok. (I had to copy the driver files to the sun/studio5u1_se/lib/ext dir to enable this) Is there a location I can unpack the drivers .jar files which will make the driver available?
I have also tried setting the CLASSPATH variable to point to the above mentioned directory..but that didn't work either. Can anyone help?
These are the exception messages that I get

Problem with JDBC results calling simple stored procedure in VC 7.0
Hi all,
I am building a simple VC model which calls a stored procedure on a JDBC database. I have created the system in the portal, defined the alias and user mapping, the connection test is fine and the VC "find data" lists my bespoke stored procedure.
The stored procedure is :
CREATE PROCEDURE dbo.dt_getBieUsers
AS
select * from dbo.emailuserlink
GO
When I test it using query analyser, it returns 3 records each with the two fields I expect - user and email address.
I drag the model onto the workspace in VC and create an input form ( with just a submit button ). i drag the result port out to create a table. This has no fields in it.
I build and deploy as flex and the app runs, I click the submit button and SUCCESS! I get 3 records in my table each with 2 fields. The data is all correct. The problem with this is the fields are determined at runtime it seems.
I go back to the table and add 2 columns "email" and "address".
i build and deploy and run the app. Again I get 3 records, but this time the contents of all of the rows is not data, but "email" and "address". The data has been replaced by the header texts in all of the rows.
Can anyone help? Why isn't the data being put in my columns as I would expect?
I tried to build and deploy the app as Web Dynpro rather than Flex to see if it was a bug in Flex. The application starts but when I click the submit button to run the JDBC stored procedure I get a 500 Internal Server Error

The JDBC connection I am using has a connection URL of jdbc:sap:sqlserver://localhost;DatabaseName=BIEUSERS
and a driver class of com.sap.portals.jdbc.sqlserver.SQLServerDriver
Can anyone solve my wierd problems?
Cheers
RichardHi Richard,
After you drag and drop the data service, right click on it and choose "Test data service". Then click on "Execute" and after you see the result on the right, click on "Add fields" button (inside the same window). Now you'll see that the fields are on the tabel. This is required only for JDBC data services, since this data (how the resultset is built) is not know in DT and it needs to be run firest - then analysed and only then you have to add the fields to the table).

Problem with jdbc:odbc returning incorrect number of rows.
Hello,
Am sure i have done something stupid, but i have an issue with jdbc:odbc ....
It is a simple sceanrio that i have coded umpteen times before ...
I have the following ....
1. Connection to DB2 on an IBM i5 (I apologise for not using native drivers from jt400.jar, but i had an ODBC code example and was in a rush - no excuse i know)
2. Statement object created from connection above
3. A string with my SQL in it
4. A result set for the results.
These are created as follows:
Class.forName( "sun.jdbc.odbc.JdbcOdbcDriver");
con = DriverManager.getConnection(ODBCSource, userID, password);
if (con == null) {
// error handling not relevant here
} else {
Statement s = con.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE);
String SQL = "select * from table";
ResultSet rs = s.executeQuery(SQL);
i then try to loop ....
while (rs.next() )
// stuff
however, i only ever get one result .... if i stick in the check for isLast, the first loop hits this check, i get my little status message, and the loop ends.
while (rs.next() )
if (rs.isLast() )
System.out.println("I am on last record");
BUT if i run the SQL
"select count(*) from table" ... i get a count of 148 !!
I tried setting the FetchSize through setFetchSize(), but made no difference.
This is running on a JBoss server 4.2.1GA, JDK is "jdk1.6.0_02" .... i have a suspicion that this may be a JBoss specfic issue, as this exact code runs just fine on the Domino platform that it was originally on, if this is the case, i apologise for wasting everyones time .... but would still appreciate any pointers you can give me.
CheersHello,
Thanks for the reply, I am not sure i follow what you are saying.
I only mentioned JBoss as it is the application server that we have deployed to and because the orignal code ran fine on a Domino server, I will take your advice and try to run it through in debug rather than running actually on the application server.
Am i incorrect in my assumption that if "select count(*) from table" gives a count of 148, i should expect 148 records in a result set created from "select * from table" ? This is all rather new to me so i apologise if this is incorrect, I'd love to know why this is incorrect so i dont make similar mistakes in future.
Also, If i run this same code on the previous platform, i get 148 iterations of the code contained within
while (rs.next() ) { ... }
When the war file is deployed to JBoss, the same SQL statement gives a result set that only iterates once for
while (rs.next() ) { ... }
The previous platform as I say was domino, but it was running as a lotus notes java agent (despite not using any notes documents etc) as it happened to be where the web pages that call this process were located. It is possible that some of the main code has changed as I had cut and paste the code into a servlet using MyEclipse, but i have double checked the bit that does this SQL request and it is identical
To complete the picture, the new servelt is then called from the action tag on the submit form on a JSP, when it ends the servlet redirects via the requestdispacher to success or failure jsp pages depending on the outcome of the processing.
Thank you again for your help. -
E61: sip problem with Gizmo, cannot make call
I register for Gizmo few days ago. I cannot make any call out (to 411, 1-747xxx numbers, any landline, any mobile )
I cannot hear the other side, but the other side hears my voice
what's wrong?
I'm using the latest v3 firmwareI have some problems with Gizmo as well. Not exactly the same problem as yours. In my case, initiating a call takes too long (~1 minute). I would recommend trying Truphone. It is another SIP-based app; and in my opinion, much better than Gizmo.

Problems with jdbc and .jar files.
I am having a problem with connecting to my database when running my .jar file as an executable.
It connects correctly when I use the java command in command prompt and it also runs correctly when using my IDE.
Is there something that needs to be added to the manifest or in the code it self inorder for the program to find the JDBC driver correctly?This is the error message that I get:

Do_open() problem with JDBC oci8 driver
I am using the JDBC-OCI driver for NT (jdbc817jdk12-nt.zip). I get a 'unresolved link error': do_open() exception stack trace when I connect to the Oracle 8i DB. I can connect successfully via SQLPlus to the same. I have Oracle 8.1.7 client installed on the system. I also have my PATH pointing to the ORACLE_HOME/bin directory where the ocijdbc8.dll is located.
Prelimnary analysis shows that the driver's Java layer is not finding the method do_open() in the .dll via JNI.
How do I resolve this?. Thanks.Hi Balakris;
I am experiencing the same problem with OCI8. Since you posted your message over 2 weeks ago I am hoping you have solved the problem. If so could you add the solution to this topic?
Thanks

Problem with JDBC Connection for HDB hanadb 02
Hi folks,
Ok I have an instance based on the 7.4 SP5 HANA CAL solution.
But when I suspend and restart the R3 system doesn't start again.
I've followed the instructions in the user guide and can access the backend instance and see that for HDB GetProcessList everything is GREEN, running
while for A4H GetProcessList everything is GREY, stopped
When I try to start the A4H instance I get
Checking HDB database
Database is not available via R3trans
Database must be started first
The messages I found on SCN suggested this might be a license problem with the HANA database, so I tried to follow the install license instructions for the HANA database via the HANA studio, but when I try to open the HDB(SYSTEM) > Properties > Licence, I then get the messages
Error while reading the licence information from system HDB hanadb 02
Reason:
Cannot retrieve JDBC Connection for HDB hanadb 02
So what do I try now?
Any suggestions?
Rgds,
JocelynThanks Ivanka! That sorted it.
For the benefit of others...the error message was found in the server log files

Im really stuck!!! any suggestions? thanks in advanceThank you for your response and sorry for the length
of code,
Thats was my first idea that it was asking for
or something I dont have but I checked my database and
I dont have any unusually large data entries (most
between 8-15 letters, the others are numbers) could it
be something wrong with how I've entered the database
in MsAccess, or am i barking up the wrong tree again!
Many thanks
RobI think you've misunderstood me. This has nothing to do with unusually large data entries, but rather the opposite. You are wrongly expecting data that is shorter than you think. When you call rs.getString(i) to retrieve a column value of a field, and you only want the first 5 characters in the column (instead of 10 or whatever the column size is), you would do something similar to the following:
String column_value = rs.getString(1).subtstring(0,5);The above expects a String that is at least 5 characters. Your problem is when your column value returned is less than the specified substring index ( in this case 5 ) it will throw an exception. If you changed your code to this, the error will not occur:
String column_value = rs.getString( 1 ).subtstring( 0, 5);
if ( column_value.length() > 5 )
column_value = column_value.substring( 0, 5 );

Newbie: Problem with jdbc-odbc and MS SQL server 2005
I'm on win vistax64 with SQLSERVER 2005 and I have set up the odbc source as system dsn using the SQL Native Client driver with SQL authentication and the connectivity test in the end succeeds.
I'm trying to make a simple web app that will connect to the database and perform simple querries. It's a school assignment.
I'm using the jdbc-odbc bridge because it's the simplest way to do it and it's what we were shown in class.
I get the following irritating error:
"Cannot establish a connection to jdbc:odb:sstmdb using sun.jdbc.odbc.JdbcOdbcDriver ([Microsoft][ODBC Driver Manager] Data source name not found and no default driver specifies)".
I'm working with netbeans 5.5.1 and this error is what I get when in the runtime tab I try to connect with the jdbc-odbc. I get a similar error in the logs when I try to run the app on the j2ee server.
This is the java class that establishes the connection.
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class Connector {
private static final String dbUrl="jdbc:odbc:sstmdb";
private static final String user="kimon";
private static final String password="jackohara";
public static Connection getConnection(){
Connection conn = null;
try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
conn = DriverManager.getConnection(dbUrl,user,password);
} catch (SQLException e) {
e.printStackTrace();
} catch (ClassNotFoundException e) {
e.printStackTrace();
return conn;
}It has worked perfectly on my school PC with winXP and MSDE2000.
What am I missing?Ok, help came from an other way where I was inquiring about a different problem:
Connectivity works fine by using User DSN instead of System DSN for the ODBC source.
Maybe you are looking for
