Below approach I tried to run and compil
for compile:
javac -cp "C:\Program Files\Java\jdk1.7.0_45\bin;D:\oracle\product\10.2.0\db_1\jdbc\lib\ojdbc.jar" OracleTest.java
for execution:
java -cp "C:\Program Files\Java\jdk1.7.0_45\bin;D:\oracle\product\10.2.0\db_1\jdbc\lib\ojdbc.jar;." OracleTest
java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver
The JDBC drivers from oracle usually include a (Java) version number in the name like ojdbc14.jar or ojdbc7.jar. I do not have Oracle installed here, so please check the correct name in your directory D:\oracle\product\10.2.0\db_1\jdbc\lib\.
You can test my DBTester program I wrote a long time ago from here. After downloading the jar - eventually you need to rename DBTester.jar.zip to DBTester.jar - just execute it in the directory you saved the jar:
java -cp "DBTester.jar;D:\oracle\product\10.2.0\db_1\jdbc\lib\ojdbc7.jar" cfh.dbtester.Main -d
(assuming the ojdbc7.jar is the driver file and using Java 7 or later)
This should print a summary for some drivers, including the Oracle one, like
java.lang.ClassNotFoundException: sun.jdbc.odbc.JdbcOdbcDriver
java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
...
java.lang.ClassNotFoundException: com.ingres.jdbc.IngresDriver
oracle.jdbc.driver.OracleDriver OK
the last line is telling me that I have the OracleDriver available.
Note: DBTester.jar creates a file named dbtester.log with its results.
Can you try with this?
"%JAVA_HOME%\bin\java.exe" -cp "%~dp0\ojdbc.jar" OracleTest.java
Important thing to note here is to have the JAR file at the same location as of your JAVA class that you want to compile/execute and accordingly change the command.
Hope this helps!

I am running TimesTen facing application in local (in eclipse IDE). URL and username and password seems to be fine. But I am getting below exception.

I checked the bin folder of TimsTen installation directory did not see ttJdbc181.dll file Instead I found ttJdbcCS.181 in the folder. I don't know why code is looking for ttjdbc181.dll file. I have tried adding ttjdbc8,9,10,11 to class path still same issue. Any help to resolve this issue will be appreciated.
Had same stack trace.
All I had to do is to add "jdbc:timesten:client:" to my connection string. It is driver and protocol as far as my understanding goes.
My connection string looks like follows:
jdbc:timesten:client:TTC_Server=127.0.0.1;TTC_Server_DSN=myDsn;UID=user;PWD=userpasswd;TCP_PORT=9999;
This was issue on Windows. Assume same would arise for Linux.
Also please ensure you have correct CLASSPATH, Lib, Include, Path environment variables.
Windows installer usually takes care of this. On Linux you have to run ttenv.sh script from directory of your installed instance, this will set env vars as required.

But when i start it says Exception in thread "main" java.lang.UnsatisfiedLinkError: no lwjgl in java.library.path.
I found on the internet that's a problem of this line
-Djava.library.path=C:\Users\Davide\AppData\Roaming\.minecraft\libraries\org\lwjgl\lwjgl\lwjgl-platform\2.9.1\
But I double checked the path is correct.
Thank you in advance.
EDIT
I solved this problem easily taking out this from the arguments:
-Djava.library.path=C:\Users\Davide\AppData\Roaming\.minecraft\libraries\org\lwjgl\lwjgl\lwjgl-platform\2.9.1\
And putting al the DLL's in the local folder, i can't still access them with the full path though
Ok i found the answer. I had to use the local path and not the absolute one
I am having some trouble connecting my java script to my SQLite3 database.
I have my directory holding my script as followed
C:/PROG/JavaPROG/programs/java_database
Inside this directory I have 3 files
Query.java, Query.class and the database query.db
My java code looks as followed
import java.sql.*;
public class Query3 {
public static void main(String[] args) {
Connection conn = null;
try {
Class.forName("org.sqlite.JDBC");
conn = DriverManager.getConnection("jdbc:sqlite:C:/PROG/JavaPROG/programs/java_database/query.db");
System.out.println("Connection Success");
} catch(Exception log) {
System.out.println("Connection Failed: " + log);
}
}
}
my classpath does contain
C:\Program Files\Java\jdk1.8.0\bin
and inside that bin directory is the sqlite jdbc driver
sqlite-jdbc-3.7.2.jar
I can connect my script to PostgreSQL database but I can't see why it isn't connecting to the SQLite3, I am getting the following error message
java.lang.ClassNotFoundException: org.sqlite.JDBC
have I done something wrong?
You need to explicitly provide the sqlite-jdbc-3.7.2.jar file in your classpath while compiling and running your classes using the -cp option. The java and javac commands will only look for .class files in the classpath and not jars.
Try this :
javac -cp <path_to_jar/sqlite-jdbc-3.7.2.jar>;. <your_class_name>.java
And if you have more than one thirdparty library, you can use a wildcard :
javac -cp <path_to_jar/*>;. <your_class_name>.java
Note that ; is the separator used in Windows. If you are on unix based systems, you need to use : instead of ;. Java maybe platform independant but the java and javac commands are not.
Also note that the . tells the java and javac commands to look in the current directory for classes. Don't forget to provide the classpath to the jars when running your program using the java command.
I have found the answer to fix this.
compile the script as normal
javac Query.java
Then specify the driver when executing
java -classpath ".;sqlite-jdbc-3.7.2.jar" Query
And it will run fine
I have followed this link, http://schemacrawler.sourceforge.net/bundled.html
I am using Oracle 11g database,
As per the doc I have downloaded the bundle for Oracle and downloaded the ojdbc driver for it (ojdbc.6.jar) and placed it in the lib folder,
then fired the command:-
-host=xxx -port=xxx -database=xxx -user=xxx -password=xxx
But its not working.
For unix its throwing error:-
-bash: -host=xxx: command not found
When I fire the command:-
java -classpath lib/*:. schemacrawler.tools.oracle.Main $* -host=xxx -port=xxx -database=xxx -user=xxx -password=xxx
It throws the error:-
schemacrawler.schemacrawler.SchemaCrawlerException: No command specified

Please help to resolve
To get help on how to use SchemaCrawler for Oracle, please use the following command:

I'm trying to run a complied class with the command:java SocketTest in current directory.
But something wrong:
Exception in thread "main"
java.lang.NoClassDefFoundError:SocketTest(wrong
name:socket/SocketTest)...
here is my classpath AND path configration in windows XP:
JAVA_HOME:
C:\Program Files\Java\jdk1.7.0_25\
classpath:
.;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar
path:
%JAVA_HOME%\jre\bin;C:\Program Files\Java\jdk1.7.0_25\bin;C:\Ruby187\bin;H:\Program Files\ARM\ADSv1_2\bin;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%JAVA_HOME%\bin;C:\Program Files\Microsoft SQL Server\80\Tools\BINN
I think the .; has been carefully written,so I'm not sure what's wrong with the java command. Someone help,please!
The error message has pointed out you need to put the your class to the corrected package socket. So you need to create folder with name socket and then put your SocketTest.class to this folder and run the following command (under the parent folder of socket):
java socket.SocketTest
