Exception in thread (JDBC for adabas D first use)
Dear my friends... I am developing a database application with Star Office, Adabas D, SuSE 8.2, Java and JDBC. This is my first experience in using JDBC and Adabas D. Usually I use PHP and MySQL. So please help me, I need many advices. I copy the adabasd.jar into the same directory where my application code (on Java language located). It is compiled successfully but it is not able to build a connection between my Adabas D and my application over JDBC. The error message is : " #prabu>java -classpath adabasd.jar konek Exception in thread "main" java.lang.NoClassDefFoundError : konek " The name of my code is "konek.java" after compiled it is "konek.class". Here is my code : " import java.sql.*; public class konek { public static void main(String[] args) { System.out.println("Hallo Indonesia"); try { Class.forName("de.sag.jdbc.adabasd.aDriver"); } catch (ClassNotFoundException e){ System.out.println("JDBC driver for Adabas D not found"); }; try { java.sql.Connection con = java.sql.DriverManager.getConnection("jdbc:adabasd://susefujitsu/prabusoft", "control", "duisburg"); } catch (java.sql.SQLException e) { System.out.println("Error " + e.getErrorCode() + " " + e.getMessage()); } } } " I don't know why it can not find the class whereas I've put the class (konek.class) on the command line to execute my compiled program. Please help. Thank you very much in advance. --------------------------------- Do you Yahoo!? SBC Yahoo! DSL - Now only $29.95 per month!

Whoops, that was pressing ctrl-enter too early :) anyways: You have to use the classpath "adabasd.jar:." This means you have to include the current dir (".") as well, seperated by a ":". Regards, -- tinus ___________________________________________________ "Words are weightless here on earth Because they're free." -- Josh Homme
Dear Tinus.
And for windows client which character should I use instead of ":."?
Because I found :
"
e:\prabu\kerja>java -classpath adabasd.jar:. konek
Exception in thread "main" java.lang.NoClassDefFoundError: konek
"
The "konek.class" and "adabasd.jar" are located under the same directory, namely : "e:\prabu\kerja". I simply copied the "adabasd.jar" into the directory.
What should I do now? Please help me.

Oh, right, in windows it might be the character ; instead of :, not sure. Try using " around the classpath as well. Regards, -- tinus ___________________________________________________ "Words are weightless here on earth Because they're free." -- Josh Homme
Dear my friend, Martijn.
I tried this :
"
sag@susefujitsu:~/arsip> set

sag@susefujitsu:~/arsip> java konek
Hallo Indonesia
JDBC driver for Adabas D not found
Error 0 No suitable driver
sag@susefujitsu:~/arsip>

But the location of the files are correct, see this
please:
"
sag@susefujitsu:~/arsip> ls

/usr/sag/aad/v1201/lib/adabasd.jar
sag@susefujitsu:~/arsip> ls /usr/sag/arsip/adabasd.jar
/usr/sag/arsip/adabasd.jar
"
Here is my code:
"
import java.sql.*;
public class konek
{
public static void main(String[] args)
{
System.out.println("Hallo Indonesia");
try {
Class.forName("adabasd");
} catch (ClassNotFoundException e){
System.out.println("JDBC driver for Adabas D not

};
try {
java.sql.Connection con =

"control", "my_password");
} catch (java.sql.SQLException e) {
System.out.println("Error " + e.getErrorCode() + "

}
}
}
"
I am still confused. No clues yet absolutely. Please
help me.
Thank you very much in advance.

Try to modify your catch block (both blocks) as: try (...) { ... } catch (...) { ... e.printStackTrace(); } Hopefully, the stack trace will give more information. -- -- Verdi March --

It seems that java is unable to find "konek". So here's what you need to verified: 1. You need to run java with [-cp ".:path_to_adabas_jar"] parameter. Notice the "." part? It instructs java to include current path when searching for classes. Without ".", you'll get "NoClassDefFOundError: konek". 2. With [-cp ".;path_to_adabass_jar"], from the previous mail, you got: Hallo Prabu JDBC driver for Adabas D not found Error 0 No suitable driver This means "konek" has been executed, but adabas jdbc driver can't be located.

Oh, right, in windows it might be the character ; instead of :, not sure. Try using " around the classpath as well.
