I have the following situation:
When accidentaly toplink loose connection with database server for short time and request coming from client in the same time toplink close connection with database server and generate the following exception:
Exception [TOPLINK-4002] (Oracle TopLink - 10g Developer Preview 3 (10.1.3.0 ) (Build 041116)): oracle.toplink.exceptions.DatabaseException
Internal Exception: java.sql.SQLException: Closed ConnectionError Code: 17008
     at oracle.toplink.exceptions.DatabaseException.sqlException(DatabaseException.java:272)
Problem is because toplink does not renew the connection with database server. Anybody know how to resolve this situation ?
Mention:
Application is build around toplink server session that serve client giving them clientsession and unitofwork.

Found a thread related to this but there it was explained that the error was occuring when trying to notify regarding output through email. In our case, issue is occuring just during scheduling itslef.
Also I haved checked the following schedular tables in my database.

+2 /+
TABLE_NAME
S_NQ_ERR_MSG
S_NQ_INSTANCE

ERROR at line 1:
ORA-02289: sequence does not exist
Please help me out in solving this as I have tried almost all possible solutions.
Thanks,

Hello,
In the delivery email configuration server page (under BI Publisher Admin Tab), the username / password to enter is the one defined on the email server itself. It is the user that will be user to send the emails when scedhuling a report.
It may not be Administrator/ Administrator (not a user defined with OBI admin tool) but the username/password defined on the email server itself.
Moreover, to properly configure the BI Publisher Scheduler, it is a prerequistes to create bipsched user on Oracle DB and install the schema tables in Oracle DB (by clicking on Install Schema button after defining database connection under Admin / Scheduler Configuration tab)
From the error your are getting 'SEQ_NAME unknown..., it appears that the tables are not created'.
Hope this helps and good luck

It's telling you that the query you read in from the console is not valid SQL, in particular that there is an error somewhere in the FROM clause of the query. To solve this problem, only type valid queries into this program. Or if you can't guarantee that -- and you can't -- report the error to the person typing in the invalid queries.

    con = driver.connect(url, info);       <--- Error here
    if (con != null)
      stmt = con.createStatement();      <--- Error here
      DatabaseMetaData dma = con.getMetaData();      <--- Error here
}So I tried this :
public static void openDB() throws SQLException {Now I do not get an error.
The OpenDB method is called from a different class like this :
public static void test1(){
    ConnectieBeheer.openDB();
    System.out.println("DB opened");
}But now it gives the same "Unreported exception; java.sql.SQLException; must be caught or declared to be thrown at line xx" error but now at the line ConnectieBeheer.openDB();
Why is this? And what can I do to correct this?
Thanks!
Steven.

you should read the sun tutoriel about exceptions handling ;
there are two ways to handle an exception : either you redirects it (using "throws" statement, what you did for the openDB method), or you catch it using a try { ... } catch (Exception exc) {}
if you want to get rid of the error what you can do is :
public static void test1(){
    try {
        ConnectieBeheer.openDB();
    } catch (java.sql.SQLException sqle) {
        sqle.printStackTrace();
    System.out.println("DB opened");
}

Exception java.sql.SQLException: [Microsoft][ODBC Microsoft Access 97 Drive

Hi,
I am writing a simple program wihich will display the list of table for a given database. Currently I am using JDBC-ODBC bridge for accessing MS Acccess data base. When I call getTables method of DatabaseMetaData. Following Exception was thrown. Any clue what could be the reason for this?

rs = dbmd.getTables( null, "DBIS", "A%", strTables);
Thanks in advance

Hi Krishna,
First, do you have a correct ODBC setup on the platform your working on -- data source, etc.
Second, please enclose the Java code for your connection, etc..
Good luck!

A word of honest advice: If you don't understand much of Java, and specifically, if you don't understand how checked exceptions work, you're in over your head looking at JDBC. Step away from it for now, and learn the basics a bit better. Seriously, if you soldier on this way, you'll never really understand what you're doing

Java.sql.SQLException: Unexpected token: IN in statement

I use Toplink 2.0-b41-beta2 (03/30/2007) and have a problem with the following JPQL query:
“SELECT DISTINCT OBJECT(e) FROM Entry e WHERE e.location IN (SELECT loc From View v JOIN v.viewLocs vl JOIN vl.location loc where v.code = :code)”
“Entry” is a subclass of “TrainElement”, location points to Entity Location. Entity View has a one-to-many relationship to ViewLoc whereas each ViewLoc has a relationship to a Location object.
Toplink creates the following incorrect sql statement – I inserted some CRLF for better readability::
Local Exception Stack:
Exception [TOPLINK-4002] (Oracle TopLink Essentials - 2.0 (Build b41-beta2 (03/30/2007))): oracle.toplink.essentials.exceptions.DatabaseException

AND ((t3.VIEWLOC_VIEW_ID = t4.VIEW_ID) AND (t2.LOC_ID = t3.VIEWLOC_LOCACTION_ID))))) AND (t0.TRAINELEMENT_TYPE = ?)) AND (t1.LOC_ID = t0.ENT_LOC_ID))]
Error Code: -11

     bind => [ROMAN W-Pb, ENT]
There sould be a “t0.ENT_LOC_ID” before the IN in the WHERE clause and the implicit join “ID FROM TRAINELEMENT t0, LOCATION t1” seems incorrect to me. At any rate the database (HSQLDB) rejects that incorrect sql statement.
How can I circumvent that problem?
A add the relevant mapping part of the involved classes.
@Entity
@DiscriminatorValue("ENT")
public class Entry extends TrainElement implements IEntry {
     @ManyToOne(cascade = CascadeType.ALL)
     @JoinColumn(name = "ENT_LOC_ID", nullable = true)
     private Location location;
@Entity
@Table(name = "LOCATION")
public class Location implements ILocation {
     // persistent part
     // primary key field
     @Id
     @GeneratedValue
     @Column(name = "LOC_ID")
     private Long id;
     @Column(name = "LOC_CODE", nullable = false)
     private String code;
     @Column(name = "LOC_NAME", nullable = false)
     private String name;
@Entity
@EntityListeners(EntityListener.class)
@Table(name = "VIEW")
public class View implements IView {
     // persistent
     // primary key field
     @Id
     @GeneratedValue
     @Column(name = "VIEW_ID")
     private Long id;
     @OneToMany(mappedBy = "view", cascade = CascadeType.ALL)
     private List<ViewLoc> viewLocs = new ArrayList<ViewLoc>();
@Entity
@Table(name = "VIEWLOC")
@EntityListeners(EntityListener.class)
public class ViewLoc implements IViewLoc {
     // persistent fields
     // primary key field
     @Id
     @GeneratedValue
     @Column(name = "VIEWLOC_ID")
     private Long id;
     @ManyToOne(cascade = CascadeType.ALL)
     @JoinColumn(name = "VIEWLOC_VIEW_ID", nullable = false)
     private View view;
     // direct Linking to the infrastrucutre location
     @ManyToOne(cascade = CascadeType.ALL)
     @JoinColumn(name = "VIEWLOC_LOCACTION_ID")
     private Location location;
….

IN doesn't support objects, only state_field_path_expression that must have a string, numeric, or enum value.
Try using
“SELECT DISTINCT OBJECT(e) FROM Entry e WHERE e.location.id IN (SELECT loc.id From View v JOIN v.viewLocs vl JOIN vl.location loc where v.code = :code)”

Chris

Toplink Error java.sql.SQLException: No suitable driver Ms Sql Server 2005

Hi All,
My requirement is to insert document to Ms SQL 2005 DB, the field type for document is IMAGE. I have configured Oracle TopLink - 10g Release 3 (10.1.3.3.0) for performing the operation.
While inserting it is giving me error saying "Internal Exception: java.sql.SQLException: No suitable driverError Code: 0".

Similar error getting while running from OC4J container. Also tried providing different values to <connection-url></connection-url> example jdbc:sqlserver://10.183.106.145:1433;databasename=master. Also tried by replacing <connection-url> with <datasource>. Let not able to pass through. Not able to figure-out what is the values for <connection-url> ..
Can anybody help me in resolving this error

Try connecting directly through JDBC, it seems that your JDBC driver is not accepmting your URL.
In TopLink you may also need to use direct connecting (DatabaseLogin.useDirectDriverConnect()).

TOPLINK-4002: java.sql.SQLException: No suitable driver

Good Day,
I'm building a simple test where a BPEL is using a Database Service; it's set up to talk to an XE database (Oracle JDBC) option. The IDE works great but when I try to run the BPEL the following error occurs:
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"><env:Header/><env:Body><env:Fault xmlns:fpre="http://schemas.oracle.com/bpel/extension"><faultcode xmlns="">fpre:remoteFault</faultcode><faultstring xmlns=""/><faultactor xmlns=""/><detail xmlns=""><summary>null: Exception occured when binding was invoked.

</summary></detail></env:Fault></env:Body></env:Envelope>
After reading a few threads I'm still confused as to what to do here; it seems that I must copy some jar files in some lib folder - it's not clear to me what jars, from where and to where; the jars must be somewhere as the IDE works; I'd greatly appreciate if someone can answer this.
Then why does everything work fine in the IDE but when I deploy there's problems - shouldn't everything be bundled with the IDE and server; I'm not using some strange 3rd party data store?
Further I'd like to know when using some of the other services is this behavior to be expected - must you manually configure them somewhere and copy jars?
Regards
J

Hi Everyone,
I managed to sort this one by doing the following:
1. Copy the jar files from $JOH\jdbc\lib to $JDEV_USR_DIR\workspace\system11.1.1.0.22.47.96\o.j2ee\embedded-oc4j\applib.
2. Edit the connection from the DatabaseAdapater tab and ticked both Save and Deploy Password buttons.
After this I restarted the whole lot; it's now talking to the database which is most useful.
Hope this helps others.

What is wrong with my sql query and please help me.
Regards
Lutchumaya

Hi Lutchumaya,
Just a litlle advice: use the SQL Worksheet (Jdev menus: Tools-> SQL Worksheet) in order to test your query, you immediatly know if the error is coming from the sql or from your code (maybe the "?" is not correctly replaced at runtime?)

Java.sql.SQLException: Error in allocating a connection

hi,
I have developed enterprise application using net beans IDE 5.5.I created one enity bean using sql server database.When i tried deploy this project i am getting following error...
Internal Exception: java.sql.SQLException: Error in allocating a connection.
Cause: Class name is wrong or classpath is not set for : com.microsoft.jdbc.sqlserver.SQLServerDataSourceError
can anybody please help me.....where i went wrong...i am new to netbeans IDE
regrds
patel

u need to download the three jar files.
download the following jar files and add in ur classpath.
msutil-2000.sp2-lib.jar
msbase-2000.sp2-lib.jar
mssqlserver-2000.sp2-lib.jar
This is sample program...
u can test in standalone first and do in netbeans....
import java.sql.*;
public class querybean {
public String getdata(String sql) {
     try {
System.out.println("testing connection ");
          Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
     Connection connection = DriverManager.getConnection("jdbc:microsoft:sqlserver://localhost:1433;databaseName=master;user=sa;password=userpass;");

} catch(Exception e1) {
System.out.println("exception caught" + e1);
return "";
public static void main (String args[]) throws Exception {

qb.getdata("select * from sampletable");
I belive it will work now
