Problems with Database connection from a servlet

Hi everybody:
I got the following message:
java.lang.ClassNotFoundException: weblogic/jdbc/oci/Driver
when I try to connect to a Database.
public Connection getConnection()
Connection con = null;
Driver myDriver = null;
try
Properties props = new Properties();
props.put("user", "fangc");
props.put("password", "fangc");
myDriver = (Driver) Class.forName("weblogic.jdbc.oci.Driver").newInstance();
con = myDriver.connect("jdbc:weblogic:oracle:occd01", props);
catch(Exception e)
System.out.println("Connection failed! - " e);
finally
return con;
What am I doing wrong? I try the code without problem for a simple Java Client

I got the following message:

myDriver = (Driver) Class.forName("weblogic/jdbc/oci/Driver").newInstance();
Make sure your servlet code is just like the right way that you have it
below:
myDriver = (Driver) Class.forName("weblogic.jdbc.oci.Driver").newInstance();

  • Problem with database connectivity

    Hi guys,
    I'm having a problem with database connectivity . I'm using the mySQL database & org.gjt.mm.mysql driver.
    I've kept the org folder under the directory where the Database.java program is residing .
    My program is as follows:
    import java.sql.*;
    public class Database
         Connection con;
         public void connect()
              System.out.println("In connect.");
         public Connection connectDB(String username,String password,String database)
              try
                   Class.forName("org.gjt.mm.mysql.jdbc.Driver");
                   String url="jdbc:mysql:"+database;
                   con=DriverManager.getConnection(url,username,password);
              catch(SQLException e)
                   System.out.println("SQL Exception caught:"+e);     
              catch(Exception e)
                   System.out.println("Exception e caught:"+e);

              Database db=new Database();
              c=db.connectDB("root","","//192.168.0.2/squid");

              c.close();
              catch(Exception e)
                   System.out.println("Exception caught:"+e);     
    It gets compiled but gives the following error when run.
    Exception e caught:java.lang.ClassNotFoundException: org.gjt.mm.mysql.jdbc.Driver
    Connection created.
    Exception caught:java.lang.NullPointerException
    I don't know why the class is not found.Pl . help me rectify my mistake.Is there any other path to be set?
    Thanks.

    You need to run it with the JDBC driver in the classpath

  • Problem with Database Connections in the designer - Catalog not updated

    This is Crystal Reports 2008 (12.2.0290). We have a number of reports that are viewed using the .Net runtime with the connection details set at runtime using ODBC to talk to SQL Server on different systems. This all works fine and is not the problem. The problem is when editing reports in the designer take the following example:
    Developer 1 creates report on their machine that references tables. DSN Name is DEV_DSN, pointing at their local database on their machine called DEV_DB1. Developer 2 needs to edit the report on their machine with a DSN of the same name (DEV_DSN) but this points to a different database on developer 2's machine called DEV_DB2.
    Developer 2 goes to the Set Datasource Location option in the Database menu to get it to point at their local DB only it doesn't work. They click on the first table included  (or the connection name) in the report and click update - they are prompted for the logon details for their local DSN/DB and supply them but they see an error indicating that there is an "Invalid object name" because the table is still being prefixed with the database name from developer 1's machine. When the table is expanded in this view the Catalog still shows as the DB name from developer 1's machine despite the connection properties above correctly showing the local DB name.
    As I say this is a design time issue not a runtime issue.
    Any ideas? Is there any way we can edit the Catalog name manually?

    Try setting the Over ridden qualified Table Name
    Set Datasource - > Tablename -> Properties
    Double click Over ridden qualified Table Name, type name as shown in in the table name field above it.
    Repeat for each table, this removes schema and db names associated with Table. Take a look at the SQL and make sure all tables are no longer prefixed.
    Report should now be totally portable.

  • Processes 'stuck' after problems with database connection

    First in the production environment, during database failover (MSSQL Server cluster), and later in testing, we encountered processes that are 'stuck' on some random operation. Admin console doesn't show stalled operation or branches, process is running, all operations are completed except last which was in several cases still in status Running, and in one case it was Completed but next operation was not started.
    When operation is still running one would expect to select it and click 'Retry' in hope that process will continue but it seems there exist a bug in "Process Instance Detail" part of the admin console - it gives an error: "This operation cannot be completed without the selection of one or more operations from the list below!"
    We can try using 'Terminate' for this operation and probably several that follow (because they would probably stall without data from first terminated operation) in hope that process which runs in big user loop can arrive at a step where it can recover from all this using existing data but it's messy and doesn't always work.
    When the operation is in status Completed admin cannot do anything at all. This completed operation cannot be retried or terminated because selection box is grayed out. Process and data in it is irrecoverably lost and must be initiated from start.
    I must say we had large problems before if database connection is lost even for few seconds (intentional fail over from one db node to another) - but now, when we filled check-connection-sql in datasource configuration Livecycle is behaving a lot better but still with above problems.
    How can it happen that LC stops executing process workflow and stops on some operation just because it wasn't able to get valid db connection for several seconds? Is it some problem with transactions or what? What can I do? Where to look?
    We are still on LC ES2 SP3. JBoss on Windows Server 2003 and MSSQL 2005.
    Any help is appreciated.

    I would suggest you to contact the Adobe support so they can look further in system as well as LC database.

  • Problem with database connectivity toolkit

    I have problem with Labview database connectivity toolkit. I build and deploy the real_web.vi (attached to the post) to the web server. It seems that the DB Tools Open Connect can not connect to the data base, and it issues the following error:

    But in highlight execution, I do not get this error! My program connects to the database and read the data. What is wrong ?
    Moreover, when I connect to the vi using the web-browser, the cpu usage of ApplicationWebServer process goes up to 100% (The same problem as stated in this post).

    Say what you will about the problems that the DCT can cause (and goodness knows I have) my suspicion is that this is not a toolkit ptoblem. When ever something only works with execution highlighting on, two words should immediately jump to mind: "race" "condition".
    Execution highlighting will muck aound with the order in which things get done in your code. Can you post what your code looks like?

  • Problem in getting the database connection from a connection pool

    Hai All,
    I am facing a problem in getting the database connection from a connection pool created on weblogic server 8.1.
    I am using the Oracle database 8.1.7.
    I have configured my connection pool, datasource and JNDI in weblogic.
    In my java program i have the following code to retrieve the connection.
    import java.sql.*;    
    import java.util.Hashtable;
    import javax.naming.Context;
    import javax.naming.InitialContext;
    class jdbcshp1 {
        public static void main(String[] args) {
         Connection connection = null;
         try {
               Hashtable ht = new Hashtable();
               ht.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");  // Wanna get rid of this.
               ht.put(Context.PROVIDER_URL,"t3://localhost:7001"); // wanna get rid of this.
               // Get a context for the JNDI look up
               Context ctx = new InitialContext(ht);
            javax.sql.DataSource ds = (javax.sql.DataSource) ctx.lookup ("myjndi1");
              //Create a connection object
              connection = ds.getConnection();
         The above code is working fine but, the two ht.put statements are creating problem.
    The problem is, after converting the application into WAR file it can be deployed
    on any machine or different port on same machine. My application fails if its deployed on
    weglogicserver which is at different port.
    Is there any way that i can get rid of those ht.put statements or any other way to solve the problem.
    any help is appreciated.
    Thanks in advance
    Pooja.

    Hai All,
    Firstly, thanks for ur reply.
    Even i have seen some code which uses context constructor with out any parameter and works fine.
    i dont understand why its not working for my code.
    When i remove those ht.put code and use context constructor with out any parameter, it giving an error.
    Context ctx = new InitialContext();
    javax.sql.DataSource ds = (javax.sql.DataSource) ctx.lookup ("ocjndi");
    connection = ds.getConnection();The error is as follows:
    javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
    the above error is forcing me to include those code but if the port number is changed the code will not work. Plz let meknow if some setting have to be made.
    I appreciate all ur valuable help.
    Thanks once again.
    Pooja.

  • I am facing a Problem with reading images from database

    Hi everybody..
    any help will be most appreciated, I am facing problem with reading images from database. I am pasting my code...

                    MySqlConnection conn = new MySqlConnection(connect); // creating connecting string

                                MemoryStream mstream = new MemoryStream(imgg);
                                pc1.Image = System.Drawing.Image.FromStream(mstream);
    It says Parameter not Valid... i am reading all the images from database

    I agree with Viorel. You are getting the error because the format of the data is incorrect probably because the data was modify. It may not be the reading of the database the is incorrect, but the application that wrote the data into the database. You need
    to compare the imgg array data with the data before it was written to the database to see if the data matches.  I usually start by comparing the number of bytes which is easier to check then compare the actual to isolate which function is changing the
    byte count.
    An image is binary data.  The standard VS methods for reading and writing data (usually stream classes) default to ASCII encoding which will corrupt binary data.  The solution usually is to use UTF8 encoding instead of the default ascii encoding. 
    Ascii encoding with stream often aligns the data and adds extra null bytes to the end of the data which can produce these type errors.

  • Problem with date format from Oracle DB

    Hi,
    I am facing a problem with date fields from Oracle DB sources. The date format of the field in DB table is 'Date base type is DATE and DDIC type is DATS'.
    I mapped the date fields to Date characters in BI. Now the data that comes to PSA is in weird format. It shows like -0.PR.09-A
    I have changing the field settings in DataSource  to internal and external and also i have tried mapping these date fields to text fields with out luck. All delivers the same format.
    I have also tried using conversion routines like, CONVERSION_EXIT_IDATE_INPUT to change format. It also delivers me the same old result.
    If anybody of you have any suggestions or if anybody have you experienced such probelms, Please share your experience with me.
    Thanks in advance.
    Regards
    Varada

    Thanks for all your reply. I can only the solutions creating view in database. I want some solution to be done in BI. I appreciate if some of you have idea in it.
    The issue again in detail
    I am facing an issue with date fields from oracle data. The data that is sent from Oracle is in the format is -0.AR.04-M. I am able to convert this date in BI with conversion routine in BI into format 04-MAR-0.
    The problem is,  I am getting data of length 10 (Output format) in the format -0.AR.04-M where the month is not in numericals. Since it is in text it is taking one character spacing more.
    I have tried in different ways to convert and increased the length in BI, the result is same. I am wondering if we can change the date format in database.
    I am in puzzle with the this date format. I have checked other Oracle DB connections data for date fields in BI, they get data in the format 20.081.031 which will allow to convert this in BI. Only from the system i am trying creating a problem.

  • Problems with retrieving data from tables with 240 and more records

    Hi,
    I've been connecting to Oracle 11g Server (not sure exact version) using Oracle 10.1.0 Client and O10 Oracle 10g driver. Everything was ok.
    I installed Oracle 11.2.0 Client and I started to have problems with retrieving data from tables.
    First I used the same connection string, driver and so on (O10 Oracle 10g) then I tried ORA Oracle but with no luck. The result is like this:
    I'm able to connect to database. I'm able to retrieve data but from small tables (e.g. with 110 records it works perfectly using both O10 and ORA drivers). When I try to retrieve data from tables with like 240 and more records retrieval simply hangs (nothing happens at all - no error, no timeout). Application seems to hang forever.
    I'm using Powerbuilder to connect to Database (either PB10.5 using O10 driver or PB12 using ORA driver). I used DBTrace, so I see that query hangs on the first FETCH.
    So for the retrievals that hang I have something like:
    (3260008): BIND SELECT OUTPUT BUFFER (DataWindow):(DBI_SELBIND) (0.186 MS / 18978.709 MS)
    (3260008): ,len=160,type=DECIMAL,pbt=4,dbt=0,ct=0,prec=0,scale=0
    (3260008): ,len=160,type=DECIMAL,pbt=4,dbt=0,ct=0,prec=0,scale=1
    (3260008): ,len=160,type=DECIMAL,pbt=4,dbt=0,ct=0,prec=0,scale=0
    (3260008): EXECUTE:(DBI_DW_EXECUTE) (192.982 MS / 19171.691 MS)
    (3260008): FETCH NEXT:(DBI_FETCHNEXT)
    and this is the last line,
    while for retrievals that end, I have FETCH producing time, data in buffer and moving to the next Fetch until all data is retrieved
    On the side note, I have no problems with retrieving data either by SQL Developer or DbVisualizer.
    Problems started when I installed 11.2.0 Client. Even if I want to use 10.0.1 Client, the same problem occurs. So I guess something from 11.2.0 overrides 10.0.1 settings.
    I will appreciate any comments/hints/help.
    Thank you very much.

Installing 11g client changed something that even using old 10g client (which I still have installed) fails to work. The same problem occur no matter I'm using 10g or 11g client now. Powerbuilder hangs on retrieving tables with more than like 240 records.

  • HELP IN DATABASE CONNECTIVITY IN A SERVLET`

    HI there,
    I have some issues in an application. I have a servlet which is called Servlet1.class. I have deployed this in my tomcat webapps folder. There is a stand alone application called MailAgent.class which pools into a mail box and retrieves the messages and converts them as HTTP messages. Then the MailAgent.class sends the HTTP message as multipart post (email message) to the servlet. In the servlet I am trying to establish a database connection with the JDBC driver from third party vendor. I am unable to get the driver class when I establish the connection with the database. Is there any issues with servlet and database access. I am able to connect if I run as a stand alone application.
    Any help would be greatly appreciated.
    Thanks
    John

    There shouldn't be any .class file in your webapps folder. I hope you mean that you created a subdirectory under webapps, with a WEB-INF under that and /classes and /lib under that. Your servlet .class file and its package directory structure belong under webapps/yourApp/WEB-INF/classes, right?
    You can create database connections in a servlet, although I agree with the previous poster that you'd be better off putting database code into objects that you could test off-line, without the servlet.
    You've got to have the JDBC driver JARs in the webapps/yourApp/WEB-INF/lib directory, for starters.
    If you get really adventurous you can create a pooled JNDI data source, but maybe that's another day's work. Get the basic connection working first.

  • Strange problem with Database LInk

    Hi Everyone,
    I have strange problem with Database Link in Oracle 11g Express Edition;
    There are two computers: computer-server and computer-client. Tnsnames.ora are the same on both computers ie.
    CT =
    (DESCRIPTION =
    (ADDRESS_LIST =
    (ADDRESS = (PROTOCOL = TCP)(HOST = krzysztof)(PORT = 1521))
    (CONNECT_DATA = (SERVICE_NAME = XE)
    I created database link :
    Create database link zdalny
    Connect to <user_id> identified by <password>
    using ‘CT’;
    Client can’t connect with server when I am using above command. But when I change “using” for using ‘krzysztof:1521’ or using ‘krzysztof’ or using ‘server IP:1521’ – everything is ok.
    Why I am asking. Because in all materials which I am reading about Oracle command with using ‘CT’ should be working correct. But there is not. Do you know, why?
    Thanks in advance and apologize for my English.

    PS. I tried with using 'XE' - not working.Assuming that is the correct tnsnames, of course XE is not working. You don't have a tnsnames entry for 'XE'.
    You need to be aware that when using a dblink, the client is the db in which the link is defined, not the desktop from which you connect to that database.
    I think you need to start here:

    The fact that your client (db link) is a database doesn't change anything taught in the above.

  • Problem with JCo Connection Pool

    Hi,
    I have a problem with using an RFC Model in my WebApplication. So sometimes the access to the function block works, and sometimes it doesn't work. Now I know, that there is a problem with the connection pool. Look at this message:
    com.sap.mw.jco.JCO$Exception: (106) JCO_ERROR_RESOURCE: Connection pool WD_X24_MODELDATA_DEST_CPIC_REKTO_DE_useDefinedUser is exhausted. The current pool size limit (max connections) is 10 connections.
    So it looks like a problem with closing the JCo Connections after using. Do know where the problem is? Because I'm using many other function blocks with no problems.

    Hello,
    You need to increase the pool size via Visual Administrator.
    Server 0 -> Services -> JCO RFC Connections.
    Change the pool size from there. I believe a restart is in order.
    Regards,
    Jan
