On the client side all you have to do is to make sure that postgresql.jar is
in your classpath.
Then use code like this to connect:
try {
Class.forName(driver);
} catch (ClassNotFoundException e) {
Error.error("ClassNotFoundException: " + e.getMessage());
}
try {
connection = DriverManager.getConnection(url,login,password);
} catch (SQLException ex) {
Error.error(ex.getMessage());
}
where driver = "postgresql.Driver";
and url = ""jdbc:postgresql://host:5432/database";
where host is the name of the host you are connecting to and database the
name of the postgresql database that you want to access.
For more info on how to connect see the postgresql JDBC driver page at

RMI on Linux
Hi, Somehow i have got RMI based server running but without RMISecurityManager installed from the server (prg). Still i don't understand why after installing RMISecurityManager from the program, it (prg) used to throw Exceptions saying permission denied which it doesn't throw now after commenting that part of installing RMISecurityManager. Anyway i have got server app running! Now the problem is that client throws exception in Naming.lookup() call saying ClassName_Stub ClassNotFoundException. Appended is the output.. before this - the client prg is able to print the list of remoteObjects on the remoteHost. ComputePi exception: error unmarshalling return; nested exception is: java.lang.ClassNotFoundException: engine.ComputeEngine_Stub java.rmi.UnmarshalException: error unmarshalling return; nested exception is: java.lang.ClassNotFoundException: engine.ComputeEngine_Stub java.lang.ClassNotFoundException: engine.ComputeEngine_Stub at java.io.ObjectInputStream.inputObject(Compiled Code) at java.io.ObjectInputStream.readObject(Compiled Code) at java.io.ObjectInputStream.readObject(Compiled Code) at sun.rmi.registry.RegistryImpl_Stub.lookup(Compiled Code) at java.rmi.Naming.lookup(Compiled Code) at client.ComputePi.main(Compiled Code) Any suggestion will be helpful. thanx, ..praks -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

Calling Same native method more than once.
Hi all,
I am facing problem in calling a native method more than once in java.
The native method('C') basically implements socket part to collect some
data from other machine.
JDK 1.2pre-v2 (glibc2.1), Linux : RedHat6.0.
It gives the correct value once, but for the second time it is called,
it core dumps with following error.
Any Help/Suggestions are most welcome.
Thanks in advance,
Nagaraj S.B.

Hello Gilles, Look at http://www.blackdown.org/java-linux/jdk1.2-status/known-bugs.html Permission on *.ttf The release packaging system didn't make the TrueType fonts world readable. If you install the JDK as yourself, no problem. If you install it as root, but are in the group that root is running when you install it, no problem.

LinuxPPC/jdk116_v5/jdk117_v1a
G'day
I've been running Blackdown JDK 1.1.7 v1a on LinuxPPC 4.0 (RedHat 5.2
libraries) and recently upgraded to LinuxPPC 1999 (RedHat 6.0). Java has fallen
in a screaming heap - I tried downloading JDK 1.1.6 v5 in case it was a problem
with 1.1.7 being an alpha release, but no dice. I'm running glibc-2.1.1-6c
(plus the devel and profile versions) if that's any help. The message that I
get from java is 'Segmentation fault'. When I run appletviewer or javac I get
the following (from javac):
/usr/java/jdk116_v5/bin/ppc/green_threads/javac: line 19: 1613
Segmentation fault `dirname $0`/${progname} $RUNTIME_ARGS -ms8m
$RUNTIME_ARGS sun.tools.javac.Main $APP_ARGS
I checked out the $JAVA_HOME/lib/ppc/green_threads directory - there are no
libdl.so or libc.so files in sight.
If you need any more info (ldconfig etc) please let me know.
Thankyou and - help!

When I need to download my experimental data from our Sparc II (SunOs) computer, it typically consists of about 7000 files totalling 200MB of data. I ALWAYS reboot to windows98 to transfer this because Ncftp (or regular Linux ftp) will give an "Arguments too long" error when I transfer with the command mget *.*. (It must be expanding the wildcard and can't handle the load of 7000 arguments...). Another piss-off from Ncftp is it will sometimes hang during mid-transfer with a " Error: Remote host has closed the connection. (Interrupt the program again to kill program.) " With CuteFTP, you can select which files you want (I've even selected over 10,000 files at once before), start the transfer and go for lunch (or whatever), when you return, its done without any complaints or excuses. I've NEVER had it fail. This is what I want from the Linux end. So, I think the Linux community needs a better, GUI driven FTP program in the style of CuteFTP. Java is well suited to develop this. -Larry Gates -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]

Re: LinuxPPC/jdk116_v5/jdk117_v1a
LinuxPPC 1999 is a glibc 2.1 release; all JDK releases
are not compatible with this particular release (in the PPC world).
However, on the CDROM you will find a test version of jdk1.2prev1.
I have not tried it, but it is rumored to work

Re: No more text in jdk1.2pre-v2 widgets
I experienced this when I installed as root, and didn't have permission to read the JRE .../fonts directory. There is a similar probelm with the JIT compiler and .../bin. This is in the known bugs list for earlier releases. On Wed, 04 Aug 1999, Gilles FILIPPINI wrote: > Hi there, > > I've just downloaded jdk1.2pre-v2.

PostgreSQL
alguem tem algum programa de exemplo ou pode fazer um pra mim de sistema JAVA conectando um banco de dados PostgreSQL...eu seria muitissimo grato... []'s Marcos Seoane -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
RE: PostgreSQL and JAVA
Go to http://www.retep.org.uk/postgres/ and dowload the JAR file for the version of
Postgres that you are using. They seem to be pretty much compatible with each other.
There are also some PDF files which you can download. This should take you through.
If you still lost, have a look at the following sample :
String dbUrl = "jdbc:postgresql://"+host+"/tour";
Class.forName("postgresql.Driver");
c = DriverManager.getConnection(dbUrl, "tour", "");
s=c.createStatement();
rback=s.executeQuery("Select username,level from users where
(userid='"+userid.getSelectedItem()+"' and password='"+password.getText()+"')");
r="";
while (rback.next())
{
r=rback.getString("username");
l=rback.getInt("level");
options.sign=r;
options.level=l;
}
c.close();
