[b]JDBC help needed[/b]

Hello,
I'm using Win2000 SP4 and J2SDK1.4.2_05 and I'm trying to connect to a remote server where Oracle9i ver. 9.2.0.1.0 is installed.
I have simply downloaded ojdbc14.jar into [Java_HOME]\jre\lib\exp\ directory, without setting a CLASSPATH
I've written this code:
import java.sql.*;
import oracle.jdbc.driver.*;
class JDBCVersion
public static void main (String args[])
throws SQLException
DriverManager.registerDriver
(new oracle.jdbc.driver.OracleDriver());
Connection conn = DriverManager.getConnection
("jdbc:oracle:thin:@HOST:1521:SID","user","passw");
DatabaseMetaData meta = conn.getMetaData();
System.out.println("JDBC driver version is " + meta.getDriverVersion());
When I'm trying to compile everything is O.K.:
c:\>javac JDBCVersion.java
but when I'm trying to run it I get an error:
c:\>java JDBCVersion
Exception in thread "main" java.lang.NoClassDefFoundError: oracle/jdbc/driver/OracleDriver at JDBCVersion.main(JDBCVersion.java:10)
And as soon as I set a CLASSPATH I'm getting this:
c:\>java JDBCVersion
Exception in thread "main" java.lang.NoClassDefFoundError: JDBCVersion
Watta hell I'm doing wrong?
Please someone HELP me, cause I'm losing my mind already.
THANKS.

I solved this problem myself
No need to set any CLASSPATH
just when run java program need to write
java -cp .;[ORACLE_HOME]\jdbc\lib\ojdbc14.jar program_name

JDBC help needed ; java.lang.NoClassDefFoundError:test1

hi, everyone, i had a problem when i run my own app to connect javadb in embedded mode
i ve added the ~/javadb/lib/derby.jar to CLASSPATH
and ~/javadb/lib/derby.jar:~/javadb/lib/derbytools.jar to DERBY_HOME
but there is a problem said my own application class cannot be found.
here is my code:
import java.sql.*;
class test1
public static void main (String args [])
       throws SQLException
     try {
        Class.forName("org.apache.derby.jdbc.EmbeddedDriver");
    } catch (Exception e) {
        System.out.println("ERROR: failed to load javadb JDBC driver.");
        e.printStackTrace();
        return;
      Connection conn = DriverManager.getConnection("jdbc:derby:testdb");
try{
     Statement stmt1 = conn.createStatement();
        ResultSet rset1 = stmt1.executeQuery( "SELECT * FROM PART" );
     long counter1 = 0;
        double price1;
     while ( rset1.next() )
         price1 = rset1.getDouble(8);
         if (price1 == 1306.4)
          counter1++;
     System.out.println( counter1 );
     stmt1.executeQuery("SHUTDOWN");
     conn.close();
   catch (SQLException e )
     String errmsg = e.getMessage();
     System.out.println( errmsg );
}and i ve followed one Derby JDBC tutorial on the internet,

      listDrivers();
    } catch (Exception e) {
      System.err.println("Exception: "+e.getMessage());

The output below confirms that the DriverManager class is able to load any JDBC driver classes as long as their JAR files are included in the classpath.

Exception in thread "main" java.lang.NoClassDefFoundError: SimpleApp
Exception in thread "main" java.lang.NoClassDefFoundError: test1
Exception in thread "main" java.lang.NoClassDefFoundError: AutoLoadJdbcDriverI assume you get these messages when you try and run the three programs mentioned (SimpleApp, test1 and AutoLoadJdbcDriver).
What commands do you use to do this? What does the command line report the CLASSPATH to be (using the echo command)?
The simplest cause would be that you have the derby jar mentioned as part of CLASSPATH, but not the current directory.

URGENT JDBC help needed. Thanks a lot~

Hi!
I have 3 java files.
1st : The INTERFACE which accepts users' input
2nd : CHECK the input, check c = new check(input);
3rd : QUERY the Database using the input, query q = new query(q);
Basically, the INPUT is passed as a parameter from one file to another file.
My question is, how to pass the query results back to the interface (i.e., the 1st java file)?
Thanks a lot~

Could you briefly write the modifications of the 3
java files needed for me please?
1st : The INTERFACE which accepts users' inputJust accepts or displays?
If displays then....
- Take ArrayList
- Extract data from ArrayList
- Put data into gui components.
2nd : CHECK the input, check c = new check(input);No changes needed.
3rd : QUERY the Database using the input, query q = new query(q);1. Create ArrayList, call it 'a'
2. Create ArrayList for each record in ResultSet, call it 'r'
3. Extract data from ResultSet row, put into 'r'
4. Put 'r' into 'a'
5. Loop back to 2 until ResultSet is empty.

Regex, jdbc help needed

I need to write a program that extracts data from a website an inserts it into a oracle database. I use HTML or JTidy to pretty the html code of the site that I am going to extract. After prettying up the code us JTidy, I save file in a tempory directory. I then would like to use regex to find and extract data between two points and multiple lines.
example:
<table>
 
 <tr>
 <td width="30%" align="right" valign="top">
 
 Project Title:
 
 </td>
 <td width="70%" align="left" valign="top">
 
 A Broad Spectrum Catalytic System for Removal of Toxic Organics from Water By Deep Oxidation
 
 </td>
 </tr>
first I would like to find the place holderProject Title: then extract the data between

 A Broad Spectrum Catalytic System for Removal of Toxic Organics from Water By Deep Oxidation
m and insert it into the oracle db
How do I do this? Once I am done with the webpage I can delete it from the temp directory. I have code that pretties the html code, and a java app that extracts data between two points. The only problem is that it has to have the same regex input. It will extract the data if the tags are identical like
data between these tags, works but
data between these tags does not. I then think I need to write a prepared or just statement to load the data into the db?
orozcom

That is not exactly what I need. This is a testing class that I have been playing with.
import java.util.regex.*;
public final class SplitTest
private static String REGEX = "<";
private static String INPUT = "one two three fourfive";
public static void main(String[] argv)
Pattern p = Pattern.compile(REGEX);
String[] items = p.split(INPUT);
System.out.println( "Length of array items: " + items.length);
System.out.println( "Item 0 of array items: " + items[0]);
System.out.println( "Item 1 of array items: " + items[1]);
System.out.println( "Item 2 of array items: " + items[2]);
System.out.println( "Item 3 of array items: " + items[3]);
//for(int i=0;i<items.length;i++)
for(int i=1;i<2;i++)
System.out.println(items);
items = null;
The out put is :
Length of array items: 3
Item 0 of array items:
Item 1 of array items: p>one two three four
Item 2 of array items: /p>five
why array item 0 empty? I would like to read between two html tags. I found some examples (sort of ) at http://www.regular-expressions.info/examples.html. It gave me the below information, but I still dont know how to implement.
<TAG[^>]*>(.*?)</TAG> matches the opening and closing pair of a specific HTML tag. Anything between the tags is captured into the first backreference. The question mark in the regex makes the star lazy, to make sure it stops before the first closing tag rather than before the last, like a greedy star would do. This regex will not properly match tags nested inside themselves, like in <TAG>one<TAG>two</TAG>one</TAG>.
any Ideas?

Help needed in HTTP to JDBC synchronous

Hi,
I am doing a interface which involves the HTTP and Database (JDBC), i need to send some two fields as request and based on the certain condition of these two fields i need to get some 4 fields as response.
Can any one please help me out in this regard so that i can atleast frame an idea and start doing the interface?
Thanks,

Hi PSV,
BPM Not Required.., just go through the blog and see how you can use JDBC Receiver adapter for Synchronous select...
Information provided in the blog is sufficient to solve your problem.

Help needed for using BASIC authentication through JDBCRealm

Help needed.
Hello,
I am doing a degree project, so far it works fine in my local machine, I need to try it on my virtual hosting (as it is a live server).
My project requires JDBCRealm, that is BASIC authentication loading access data from mysql database. Normally this setup can be done in Server.xml file, because my Tomcat hosting is a virtual one, I only have permission to access the web.xml file.
My question is: is it possible to get it done in an alternative way? In web.xml? Some properties file maybe?
Thank you very much.

You can set this up for your context using META-INF/context.xml instead of working with server.xml.
Make a directory called META-INF under your webapp ( it'll be at the same level as WEB-INF ). Under this, add a context.xml with all your context specific configuration including the realm. A sample is below
<?xml version="1.0" encoding="UTF-8"?>
<Context path="/myApp" reloadable="true">
 <Realm
 className="org.apache.catalina.realm.JDBCRealm"
 driverName="com.microsoft.jdbc.sqlserver.SQLServerDriver"
 connectionURL="jdbc:microsoft:sqlserver://127.0.0.1:1433;DatabaseName=myDB;SelectMethod=Cursor;"
 connectionName="username" connectionPassword="password"
 digest="MD5" userTable="users" userNameCol="userid" userCredCol="userpassword"
 userRoleTable="user_roles" roleNameCol="rolename"
 />
</Context>Hope this helps.

Help needed to run JSTL 1.1 in Tomcat 6.0.16

Hi All,Help needed to run JSTL 1.1 in Tomcat 6.0.16. I am trying to run the example given in http://tomcat.apache.org/tomcat-6.0-doc/jndi-datasource-examples-howto.html The example tries to connect to MySQL database from JSP using JSTL and JNDI Datasource.I am running the example using Eclipse 3.4.2 using Sysdeo plugin to start and stop Tomcat server from Eclipse IDE.
My web.xml file has <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
</web-app>
and test.jsp has proper taglib directives
<%@ taglib prefix="sql" uri="http://java.sun.com/jsp/jstl/sql" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
I have placed the jstl.jar and standard.jarof the jakarta-taglibs-standard-1.1.2.zip under E:\Deepa\workspace\DBTest\WebContent\WEB-INF\lib directory also placedcontext.xml file under E:\Deepa\workspace\DBTest\WebContent\META-INF and the content of context.xml is as below
<Context path="/DBTest" docBase="DBTest"
debug="5" reloadable="true" crossContext="true">
<Resource name="jdbc/TestDB" auth="Container" type="javax.sql.DataSource"

username="deepa" password="mysql" driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/javatest?autoReconnect=true"/>
</Context>
Now while running the example, Eclipse creates one DBTest.xml file under C:\Program Files\Apache Software Foundation\Tomcat 6.0\conf\Catalina\localhost
which has the following line:
<Context path="/DBTest" reloadable="true" docBase="E:\Deepa\workspace\DBTest" workDir="E:\Deepa\workspace\DBTest\work" />

When running the same example, by creating a local server in Eclipse(creating new Server connection pointing to same Tomcat 6.0 installation) it runs fine without any error.

Hi evnafets,
Wow, very helpful information, great insight into working of Eclipse. Thanks a lot.
I have one more question. I have a context.xml file under {color:#0000ff}E:\Deepa\workspace\DBTest\WebContent\META-INF{color} folder and that has the Resource element to connect to MySQL database:
{code{color:#000000}}{color}<Context path="/DBTest" docBase="DBTest" debug="5" reloadable="true" crossContext="true">

{color:#0000ff}url="jdbc:mysql://localhost:3306/javatest?autoReconnect=true"/>{color}
{color:#0000ff}</Context>{color}As usual when running application in local Tomcat server of Eclipse, this data source works fine. But when I run the application on Tomcat, by starting Sysdeo plugin from Eclipse, the DBTest.xml file created in C:\Tomcat 6.0\conf\Catalina\localhost has the context entry as<Context path="/DBTest" reloadable="true" docBase="E:\Deepa\workspace\DBTest\WebContent" workDir="E:\Deepa\workspace\DBTest\work">
</Context>The<Resource> element I have specified in the context.xml of \WebContent\META-INF folder is not taken into account by Tomcat and it gives the following error:May 21, 2009 5:20:04 AM org.apache.catalina.core.StandardWrapperValve invoke

JDBC Scenario need inputs

hello friends,
I have scenario, Proxy - XI - JDBC.
i need to make a scheduled insert to the database. But i can make the insert only if the the status is yes in another table.
briefly,
table - status table -> contains status whether i can insert or not
table - contact table -> need to insert data only if yes in the status table.
can we achieve this without BPM. Can we use JDBC lookup to solve this. We are using PI 7.
Please provide valuable inputs.
Thanks,
Raj

Hello,
can we achieve this without BPM. Can we use JDBC lookup to solve this. We are using PI 7.
The answer to both questions is yes. Probably you might be using the lookup api for your requirement. See blog below:
/people/alessandro.guarneri/blog/2006/03/27/sap-xi-lookup-api-the-killer
It would also help if your scenario is synchronous (since you are doing inserts) and this would eliminate the retry mechanism in async messages.
Hope this helps,
Mark

JDBC Helper Service

Hello,
The SQL Server DB Configuration in WLP Deployment Guide says JDBC Helper
Service needs to be configured for each application deployed. Do I need to
do this for other applications that has been installed and deployed
out-of-box (p13nApp, p13nConsoleApp, paymentWSApp, taxWSApp, wlcsApp,
wlpDocsApp)? I only did it for portal app so far and just got me wondered...
Thank you,

Hi,
So am I correct in thinking that the other apps are still using cloudscape

apps, make this change in all the apps.

383     S1     Biology Chemistry      Computer Science Physics
384     S2     Chemistry Computer Science Mathematics Physics
or even this is enough(what i actually needed)
COMB_ID     subjects
383           Biology,Chemistry,Computer Science,Physics
384           Chemistry,Computer Science,Mathematics,Physics
you can use any of the COMBINATION table(either (2) or (3))
and i want to know
1)which design is good in this case
(i think SUB_ID1,SUB_ID2,SUB_ID3,SUB_ID4 is not a
good method to link with same table but if 4 subjects only(and must) comes
detail table is not neccessary )
now i am achieving the result by program-coding in C# after getting the rows from oracle
i am using oracle 9i (also ODP.NET)
i want to know how can i get the result in the stored procedure itsef.
2)how it could be designed in any other way.
any help/suggestion is welcome
thanks for your time --Pradeesh

Well I forgot the table-alias, here now with:
SELECT C.COMB_ID
, C.COMB_NAME
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID1) AS SUBJECT_NAME1
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID2) AS SUBJECT_NAME2
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID3) AS SUBJECT_NAME3
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID4) AS SUBJECT_NAME4
FROM COMBINATION C;
As you need exactly 4 subjects, the columns-solution is just fine I would say.

Hi all help needed I have a canon 40D. I am thinking of buying a canon 6D.
But not sure that my lenses will work.
I have a 170mm/ 500mm APO Sigma.
A 10/20 ex Sigma HSM IF.
And a 180 APO Sigma Macro or do I have to scrap them and buy others.
ALL Help will be greatly received. Yours BRODIE

In short, I love it. I was going to buy the 5DMark III. After playing with it for a while at my local Fry's store where they put 5DMII, 5DMIII and 6D next to each other, using the same 24-105L lens, I decided to get the 6D and pocket the different for lens later.
I'm upgrading from the 30D. So I think you'll love it. It's a great camera. I have used 5DMII extensively before (borrowing from a close friend).
Funny thing is at first I don't really care about the GPS and Wifi much. I thought they're just marketing-gimmick. But once you have it, it is actually really fun and helpful. For example, I can place the 6D on a long "monopod", then use the app on the phone to control the camera to get some unique perspective on some scenes. It's fun and great. GPS is also nice for travel guy like me.

Help needed! Raid degraded again!

Hi!
Help needed! I hava made bootable RAID with two S-ATAII 250Gb HDD and its not working! Every now and then at bootup I get a message RAID -> DEGRADED... Must be seventh time! Rebuild takes its own time!
What am I doing wrong!
T: Ekku
K8N Neo4 Ultra
AMD 64 4200+
2 Gb RAM
2 x 250 Gb HDD (Maxtor)
nVidia RAID (in mb)
P.S. I wery SORRY with my poor language!

I'm going to blame the nVRAID because I've seen issues with it in the past. If your motherboard has another non-nVidia RAID solution, use that instead. Using the nVidia SATA ports as BASE or JBOD is fine and dandy but RAIDing always had issues. It's not even a driver issue I think it's just instability. Latest drivers and even boxed drivers never helped. Granted, some will report success with their rig. But on a professional level I've seen nForce issues on different motherboards and different hard drives that had RAID disaster stories.
Good luck and if you don't have another RAID solution, my suggestion would be to buy a dedicated RAID controller card.

Get over it mate !
I find it easy t read CAPS...and if you dont like it ...DONT READ IT!
And why bother to reply...some people have nothing better to do.
Yes there chep and easy to come by...Ive already got a new one.
All I wanted was to make a diagram of whats inside the bloody thing...it was a simple question and required a simple answer.
NO NEED TO A WANKA !!
I feel a bann comming up.
Have you tryed Google ? really.. your question is inrelevant. No need to reply indeed.
Why do you come here asking this question anyway ? is it becouse you have a MSI gfx card ? and the adapter has nothing to do with this ?
You think you can come in here yelling.. thinking we have to put up with it and accept your style of posting. This is not a MSI tech center.. it's a user to user center.. Your question has nothing to do with MSI relavant things anyway's.
Google = your friend.
