Setting tomcat to use jdbc

I have created a new development directory say
c:\servlets-jsp
under
It works under this directory but I does not allow me to use jdbc-odbc
How can I set it up in tomcat to do so?

I just got mine to work yesterday, so may be I can help.
Now, when you say it does not allow you to use jdbc:odbc, are you talking about the jdbc:oracle:thin?

Installing Log4J in Tomcat and using JDBC to log errors

Has anyone figured out how to install Log4J in Tomcat and use the Log4J JDBC functionality?
I have log4j.jar in CATALINA_HOME/common/lib.
I also have log4j.properties is in CATALINA_HOME/common/classes
Then when I start Tomcat I get the following error:
[main] DEBUG org.apache.commons.digester.Digester - addRuleSet() with no namespace URI
is it something to do w/ the log4j.properties file? do i have to use a xml format or is it ok to use .properties format?
-Karthik

I would say you have something wrong in your log4j properties file.
properties format is fine, but I suspect something in there is not quite right.
Try starting with a simple example one, see if it works, and then try adding your own config based on that one.
Good luck,

Help: Connecting Tomcat to CA-IDMS Using JDBC Type 4 Drivers (JNDI)

Hi there,
I have a rather interesting / complex problem......creating a connection to CA-IDMS from Tomcat using JDBC type 4 drivers (CA provide the type 4 driver).
We have a zSeries 9 IBM mainframe running CA-IDMS r16.1, and I need to connect to the IDMS from Tomcat (running on Linux) using the JDBC Type 4 drivers provided by CA.
At this stage I am struggling with the actual setup and configuration of Tomcats server.xml and web.xml files. These are the files where the JDBC configuration is set (I think). I have to setup the CA-IDMS part of the configuration, but that is a different problem. Basically there is a TCP/IP listener on the IDMS, waiting for incoming connections from the JDBC type 4 driver.
I set up a Tomcat to MySQL connection using MySQL Connector / J, which is a similar kind of process to what I am trying to achieve with IDMS. MySQL connector / J came with a jar file which is placed in Tomcats lib folder, and then the JDBC setup for the web application is created in Tomcat's server.xml and web.xml files. You can then connect to the MySQL database using JSP and the configured JDBC driver / connection. The CA-IDMS Server comes with an idmsjdbc.jar file, which I think is the JDBC typr 4 driver. I think it needs to be placed in the Tomcat /lib folder, but I dont know how to set up the configuration.
There is a JDBC DriverManager which allows JDBC drivers to connect to CA-IDMS. The DriverManager recognises the following syntax:
jdbc:idms://hostname:port/database
This allows the JDBC driver running within Tomcat to connect to the IDMS which is running on the IDM mainframe. CA IDMS r16 supports direct connections from the Type 4 JDBC driver to the Central Version on IDMS. "hostname" is the DNS name or IP address of the machine where the CV is running, and "port" is the IP port that was specified for the listener PTERM (setup on the IDMS side).
There is a caidms.properties file for the JDBC driver, which is used to specify user ID, password, and optional accounting information. It can also be used to specify physical connection information, allowing an application to connect to a CA-IDMS database without requiring the definition of an ODBC style data source. However, I dont know where to place this file within the Tomcat setup.
There is also an IdmsDataSource class. I dont know where to configure this or how to set it up; the CA-IDMS Server manual states the following:
This class implements the JDBC DataSource interface. It is used with an application server (Tomcat) providing Java Naming and Directory Interface (JNDI) naming service to establish a connection to a CA IDMS database. IdmsDataSource properties conform to the Java Beans naming conventions and are implicitly defined by public setter and getter methods. For example, the description property, which is required for all DataSource implementations, is set using the setDescription(String) method. The application server may use the java.lang.reflection methods to discover DataSource properties and provide an interface to set them, or may simply require that they are defined in some configuration file. IdmsDataSource properties are used to specify the connection parameters. These properties are the equivalent of the DriverPropertyInfo attributes described in the previous section and can be used to completely define the parameters needed to connect to a database. Like a URL, an IdmsDataSource object can also reference an ODBC style data source name, where the connection parameters are defined in the configuration file on Linux.
Is there anyone that can try to point me in the right direction to setting up the JDBC connection? I am totally new to Java and so the instructions are not making much sense at the moment. Any help, hints, tips..anything will be greatly appreciated as I have just hit a brick wall here. I can't find much to do with setting up the CA-IDMS Server JDBC type 4 driver online either....if anyone can point me to some resources that would also be extremely useful.
Kind regards
Jp

You say you've managed to get the JDBC driver working
in an application but not in a JSP. You also say that
the error you get is
"com.microsoft.jdbc.sqlserver.SQLServerDriver".
I'd be willing to bet that the exception that you have
got is a ClassNotFoundException. I.E. your application
server hasn't found the JDBC driver classes. The
application server probably doesn't use your current
CLASSPATH to look for classes. It will be setup within
the application server in some way and you'll need to
check your app server documentation to see how it is
done.
Try replacing
e.printStackTrace();with
e.printStackTrace(out);to get a full stack trace of your error.
ColTried it. Got this error when I tried to run the JSP.
Incompatible type for method. Can't convert javax.servlet.jsp.JspWriter to java.io.PrintWriter.
e.printStackTrace(out);
I'm currently using Apache Tomcat 4.0.3 as my JSP/Servlet Container.
I'm also using Type 4 MS SQL Server 2000 JDBC driver version 2.0 on my NT4.0 Server.
Do I need to set my JDBC driver in my container? if so, how do I do that?

Memory Leak when TOMCAT connects to Oracle 10g RAC using JDBC Thin driver.

We had experienced Memory leak when a Oracle 10g (10.2.0.3) RAC node was evicted. TOMCAT app server is connecting to the Oracle 10g RAC database instances using JDBC 10.2.0.3 thin driver.
Anyone had similar experience?
Any ideas? Any bugs reported/fixed?
Thanks,
Raj

If you're doing XA, we absolutely do not support
driver-level load-balancing OR failover. Use neither.
For non-XA, you can use driver-level failover. For
non-XA, you could set load-balancing, but it won't
help because we get connections from the driver,
and keep them indefinitely, so the driver never gets
the chance to affect which connections the pool
uses after that.

Help setting Parameters using JDBC and Bind Variables for Oracle List

I fully understand the concept of using Bind Variables when using JDBC to avoid hard parses everytime my SQL statement is executed when only a certain value changes. For example, perhaps I have the following statement:
PreparedStatement ps = con.prepareStatement("select salary from employees where employee_id = ?");
I would then set the value of the question mark (the first and in this case only parameter) using:
ps.getStmt().setString(1,empId1);
That is assuming I have the variable empId1 populated with what I want. Anyway, my question has to do with Oracle lists. In other words, if I am just executing the statement against the db, it might look like:
select salary from employees where employee_id in ('123','456','789');
I still want to use bind variables and I can do it in JDBC with something like:
select salary from employees where employee_id in ('123','456','789');
ps.getStmt().setString(1,empId1);
ps.getStmt().setString(2,empId2);
ps.getStmt().setString(3,empId3);
BUT, what if I just want to construct my list of ids upfront as a string and do something like:
select salary from employees where employee_id in (?)
ps.getStmt().setString(1,listOfEmpIds);where listOfEmpIds would look something like '123','456','789'.
That's what I want to do but it doesn't work. It would be treating the list as a single parameter as opposed to lots of individual parameters. Can someone please tell me the syntax for this if it is possible? I have tried where XX in (?) and where XX in ? (and the string I substitute has the parenthesis in it), but neither work.
Thank you for your help.

I always build the list myself.
You could, however, pass the list as a varchar to a stored proc and then have the stored proc parse (or dynamically execute) using it.
The second method might even be faster although I would suspect that is only going to be the case if the list is very large. Or it might not.

How can I see KSC5602 character set using JDBC thin driver

After I change character set from USASCII7 to KO16KSC5601, I
cannot see korean from the clients
using JDBC thin driver.
But, I can see korean clearly using sqlplus at serer, or
application using SQLNet.
I use Oracle Enterprise Server 8.0.4.1.0, jdbc thin driver
8.0.4.0.6 on Windows 98. I read that all bugs realated
to multibyte language are fixed in Oracle8. What can I do to
solve this problem?
PS.server: Oracle 8.0.4.1 on Digital Unix 4.0b, client: jdk1.1.8
on Windows98. I used the command.
null

The easiest thing to do is download it as an archive with your applet.
Otherwise, you have to have the files on every client machine.
For netscape, put the classes111.jar in the java classes folder typically:
c:\ProgramFiles\Netscape\Communicator\Program\java\classes.
I'd expect that IE would be setup in a similar way.

Using JDBC Persistent Manager for Tomcat across multiple Servers

Sorry if I word this question incorrectly, but I hope you can get the gist of it. Basically, I have a web application that will be running on 2 different machines. When too many users are on one machine, they are switched over to another machine (load balancing). If I use JDBC (or file) Persistance Manager to store sessions, what happens when a user is switched between machines? If both machines use the same settings for the Persistance Manager, when a user has just been moved to a new machine, will it be able to load the session from the DB? (since it should have its sessionID). If you can not do this, is there a way to do it?
Thanks!

Thanks!Session ids are unique and cannot be transferred between different servers... Wise web servers supports load balancing and should be able to transfer/store session without your special code. If you still keen to write transfer code yourself you have to:
1) Store not only session id, but also all content of session (including some virtual (your) session id
2) Transfer (i.e. create a copy) stored session content to another machine

How to use JDBC Connection Pools in a standalone application?

Hi, there,
I have a question about how to use JDBC Connection Pools in an application. I know well about connection pool itself, but I am not quite sure how to keep the pool management object alive all the time to avoid being destroyed by garbage collection.
for example, at the website: http://www.developer.com/java/other/article.php/626291, there is a simple connection pool implementation. there are three classes:JDBCConnection, the application's gateway to the database; JDBCConnectionImpl, the real class/object to provide connection; and JDBCPool, the management class to manage connection pool composed by JDBCConnectionImpl. JDBCPool is designed by Singleton pattern to make sure only one instance. supposing there is only one client to use connection for many times, I guess it's ok because this client first needs instantiate JDBCPool and JDBCConnectionImpl and then will hold the reference to JDBCPool all the time. but how about many clients want to use this JDBCPool? supposing client1 finishes using JDBCPool and quits, then JDBCPool will be destroyed by garbage collection since there is no reference to it, also all the connections of JDBCConnectionImpl in this pool will be destroyed too. that means the next client needs recreate pool and connections! so my question is that if there is a way to keep pool management instance alive all the time to provide connection to any client at any time. I guess maybe I can set the pool management class as daemon thread to solve this problem, but I am not quite sure. besides, there is some other problems about daemon thread, for example, how to make sure there is only one daemon instance? how to quit it gracefully? because once the whole application quits, the daemon thread also quits by force. in that case, all the connections in the pool won't get chance to close.
I know there is another solution by JNDI if we develop servlet application. Tomcat provides an easy way to setup JNDI database pooling source that is available to JSP and Servlet. but how about a standalone application? I mean there is no JNDI service provider. it seems a good solution to combine Commons DBCP with JNID or Apache's Naming (http://jakarta.apache.org/commons/dbcp/index.html). but still, I don't know how to keep pool management instance alive all the time. once we create a JNDI enviroment or naming, if it will save in the memory automatically all the time? or we must implement it as a daemon thread?
any hint will be great apprieciated!
Sam

To my knoledge the pool management instance stays alive as long as the pool is alive. What you have to figure out is how to keep a reference to it if you need to later access it.

Using JDBC to update nvarchar (foreiegn character data)

We have an application that updates tables in Oracle with foreign character data. The database character set is not UTF-16 but nvarchar columns are set to be nvarchar.
The application is working correctly in our development environment (using ORAOLEDB to connect to the server with the NDATATYPE value set to true). The development env is Eclipse/Tomcat 5.5/JRE 1.4
Our production environment is Weblogic using JDBC. In this environment we cannot correctly update our database with ???? written to the database.
What can we do to fix this issue?
Tks

Mark,
I believe Kuassi Mensah has an example of this in his book.
Sorry but I don't have my copy handy now.
Just search for his threads in the forum archives: Not just this one.
Try the JDBC forum and the Oracle database JVM forum.
Basically you can load the DB2 JDBC driver into Oracle database and then use a java stored procedure to get the data.
Good Luck,
Avi.

How can i put a file into blob using jdbc !?

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 :

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.
D.T.

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?

Problem using Jdbc-Odbc Bridge

Hi,
I am using Java 2 SDK and I am trying to access MS Access database on my machine using Jdbc-Odbc bridge. I have set up the DSN in ODBC. But I get the following error when I run my program -
'No Suitable Driver'
Here's my code snippet-
Class.forName ("sun.jdbc.odbc.JdbcOdbcDriver");
String dsn = "jdbc:odbc:DriverInfoDB";
Connection con = DriverManager.getConnection(dsn,"","");
con.setAutoCommit(false);
Statement stmt;
String query = null; // SQL select string
ResultSet rs; // SQL query results
stmt = con.createStatement();
.....etc etc...
Where is the error in this code??
Help Needed!!
Thanks
Vivek.

try
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con = DriverManager.getConnection(dsn,"guest","guest");
OR DriverManager.getConnection(dsn);
System.out.println("Conection's opened");
catch(ClassNotFoundException cnfe)
System.err.println(cnfe);
catch(SQLException sqle)
System.err.println(sqle);
try that code and double check you DSN Name . it's a good practice to greate a system DSN.
i hope that helps.

Using JDBC to perform spatial queries using SDO operators

Hi,
I want to create a routine to perform the SDO_ANYINTERACT function based on a rectangle as in the following query:
select LINK_ID from SDO_LINK where
SDO_ANYINTERACT ( SDO_LINK.LINK, SDO_GEOMETRY(2003,8307,NULL,
SDO_ELEM_INFO_ARRAY(1,1003,3),
SDO_ORDINATE_ARRAY(-122.38845,37.78889,-122.38651,37.78923))) = 'TRUE'"
This query works fine when passed to the executeQuery method of a JDBC Statement. But when I tried to create a PreparedStatement and set the 4 parameters (lon1, lat1, lon2, lat2) that are passed to the SDO_ORDINATE_ARRAY function:
          String sql = "select LINK_ID from SDO_LINK where " +
               "SDO_ANYINTERACT ( SDO_LINK.LINK, SDO_GEOMETRY(2003,8307,NULL,SDO_ELEM_INFO_ARRAY(1,1003,3),SDO_ORDINATE_ARRAY(" +
               "?,?,?,?" +
               "))) = 'TRUE'";
I am getting an Oracle exception:
java.sql.SQLException: ORA-03115: unsupported network datatype or representation
I have tried setting the parameters using setString as well as setFloat methods but still get this error.
Does anyone know what I am dong wrong? Anyone have an example of calling SDO_ANYINTERACT or other SDO operators via JDBC?
Thanks

Getting the connection is straightforward:
try {
Class.forName("oracle.jdbc.driver.OracleDriver");
} catch (ClassNotFoundException e) {
throw new SQLException (e.toString());
Connection conn = DriverManager.getConnection(connURL, userName, userPass);
I have validated that my query executes and returns results fine when I pass the entire query as a string to executeQuery:
String sql = "select LINK_ID from SDO_LINK where SDO_ANYINTERACT ( SDO_LINK.LINK, SDO_GEOMETRY(2003,8307,NULL,SDO_ELEM_INFO_ARRAY(1,1003,3),SDO_ORDINATE_ARRAY(-122.38845,37.78889,-122.38651,37.78923))) = 'TRUE'";
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery(sql);
// Iterate through result set here
The issue is I am not sure how to pass the 2 (lon,lat) cooridnates fior the SDO_ORDINATE_ARRAY operation in a prepared statement . Perhaps I have to just construct a string?
For example, doing the following:
String sql = "select LINK_ID from SDO_LINK where " +
     "SDO_ANYINTERACT ( SDO_LINK.LINK, SDO_GEOMETRY(2003,8307,NULL,SDO_ELEM_INFO_ARRAY(1,1003,3),SDO_ORDINATE_ARRAY(" +
     "?,?,?,?" +
     "))) = 'TRUE'";
if (conn == null)
     openConnection();
PreparedStatement pstmt = conn.prepareStatement(sql);
pstmt.setFloat(1, Float.parseFloat(lon1));
pstmt.setFloat(2, Float.parseFloat(lat1));
pstmt.setFloat(3, Float.parseFloat(lon2));
pstmt.setFloat(4, Float.parseFloat(lat2));
Then calling:
ResultSet rs = pstmt.executeQuery(sql);
Which results in the exception.
Actually, I found the problem. I want to NOT pass the sql string to the executeQuery statement when using the PreparedStatement.
The following works:
ResultSet rs = pstmt.executeQuery();
