I want to learn Java programing language and MySQL in linux.What packages do I've to install?Are there any sites providing basic tutorials of java and MySQL?
View 1 RepliesSites providing video tutorials on linux which are free to download. I've got one site "www.showmedo.com". Here I can get different tutorials on opensource like scribus, gimp, C++,python etc.
Can anyone provide me any other good sites like this?
Do I have to do a basic configuration / initialization of mysql, like described in the following link, before I can use it? [URL] The background is, that I want to use mythtv and therefore I need a working mysql. When I tried to create the needed database, as described in the file README.SLACKWARE (included in mythtv.Slackbuild package from slackbuilds.org) with the following command, I got an error:
# mysql -u root -p < /usr/share/mythtv/database/mc.sql
The error message was:
ERROR 1146 (42S02) at line 3: Table 'mysql.servers' doesn't exist
-- integrale
I don't remember that I ever did a basic configuration but mysql was already used by joomla, and it worked right out of the box.
I just installed FC13 and am having a problem with Java sites in Firefox. Everything is a fresh installation from the LiveCD (Gnome) and I'm dual booting with XP.
My laptop is an older Presario 2170us / 2G Celeron / 512 Ram / 40 G HDD.
If I go to the preferences of Firefox and disable Java, I don't have the issue but I can't open sites that are Java-intensive, such as AOL.
Once I re-inable Java and open Firefox, as soon as I get to AOL, I am dumped out of the Gnome GUI to the plain text list of startup items, then returned to the FC login screen and then I get back to the desktop.
When I open Firefox again, I get a page about the failure to open AOL... but I don't restore it...instead, I open a new site (such as this Forum), then close Firefox and reopen it.... but when I go to AOL, it happens all over.
As a recent (almost) convert from Ubuntu, I'd like to solve this. I used FC10 on my laptop but had too many SE-Linux issues (I couldn't do much without generating an error), so I went back to Ubuntu. I tried FC11 and FC12 but still had some problems. Now I'm trying FC13 and like what I'm seeing so far...except for what appears to be a Java issue in Firefox.
I am using F13 and new to Linux, whenever I am browsing internet that contains java script, the browser crashes, showing error signal as:
Package: firefox-3.6.3-4.fc13
Latest Crash: Wed 04 Aug 2010 12:00:09 PM
Command: /usr/lib/firefox-3.6/firefox
Reason: Process /usr/lib/firefox-3.6/firefox was killed by signal 11 (SIGSEGV)

Bug Reports:
I also used google-chrome browser, same problem is arising there too.
In the past week or so I've noticed some weird network behaviour. I find accessing some sites such as Amazon, Paypal, and Bigstockphoto really slow. Sometimes the page will not load at all. Other sites are fine. The problem sites are not a problem for others on my LAN at home. When I try to open the problem sites, I can see in Firestarter blocked connections coming from 2.1(8/9).xxx.xxx on various ports such as 36007. This only happens for the problem sites. I attached a typical output from firestarter.
This happens with Firfeox or Chrome. Using Ubuntu 10.10
I have recently installed Java in my Ubuntu 9.04 environment so that I can teach myself Java. Basic Java programs work, but I am having trouble connecting to a MySQL database. I installed these packages using Synaptic Package Manager.
1.gsfonts-x11
2.java-common
3.odbcinst1debian1
4.sun-java6-bin
5.sun-java6-jdk
6.sun-java6-jre
7.unixodbc
After these packages were installed, I was not sure if I needed to do this, but I downloaded the MySQL connector from MySQL :: MySQL Connectors and installed in a directory called /home/mark/mysql/.
I then did "sudo gedit /etc/environment" and added a CLASSPATH to where I installed the connector:
Code:
I found an example Java program from Using JDBC with MySQL, Getting Started and stripped it down even further to test the MySQL connection.
This is the program I am running:
Code:
Could not find the main class: Jdbctest. Program will exit. I am new to Linux, Ubuntu, Java and MySQL, so I have probably left out something that is very obvious.
I'm trying to use MySQL's JDBC connector for java but even though I set the CLASSPATH variable, java cannot find the com.mysql.jdbc.Driver class.
Code:
[jordan@Jordan-Laptop java-stuff]$ ls /usr/share/java
cal10n geronimo-jta.jar java_cup-runtime.jar
[code]...
due to some issues i uninstalled openjdk shipped default on my opensuse 11.3 and installed jdk 1_6_21 from a .bin file. Its installed to usr/java/jdk.The mysql connector is also present in the same but running a java program that connects to mysql gives me the errorjava.sql.SQLException: Unknown initial character set index '192' received from server. Initial client character set can be forced via the 'characterEncoding' property.the code i tried is
import java.sql.*;
import java.io.*;
class mysql_conn_tester
[code]...
I have installed open suse linux 11.3. I have mysql database and jdk 1.6.20.0. How do I connect from java to mysql database?
View 2 Replies View RelatedI want to ask how i set Linux class path for mail.jar and mysql-connector.jar. I have set the class path for java with the command.
Code:
when i do java -version it's work fine.
Also if i want to know that what shell i am using how can i find it.Also what is the command for showing class path variables or how can i see my JAVA_HOME class path.Means after setting the class path for above two files how can i see that these files have added.
When i write echo $CLASSPATH or echo $JAVA_HOME it shows nothing no error but again shows the prompt.
One thing more i want to run a java program on Linux it is in a package (named asteriskproject). It consist of 10 java files. I have run this program on windows using netbeans IDE.For this program i need to set my Linux class path for the above mentioned files, and this is my first time that i am running any program on Linux. So i want to ask how can i run my program. Simply put this asteriskproject directory in any folder and run the main file using javac. Is it right way to run the program that consist of package ?

I trying to set up a cluster of 4 nodes each with CentOS 5.3,
i want to rsh from one node to other without providing the password.
so far i did the following:
1)configured /etc/hosts file on the nodes so that each node can be pinged from other.
$cat /etc/hosts
10.0.2.100 node1
10.0.2.101 node2
10.0.2.102 node3

I am not able to figure out what to do next ? Do i need to be at /home/mygrid location on node1 in order to rsh into node2 ?
I currently run Win 7 and want to upgrade my computer to a server to accomplish the following... I have a VPN Service. I want the server machine to connect to a VPN providing a secure connection. Then, I want all the machines in the house (windows based) to connect through the server onto the VPN connection. Hopefully this makes sense. Would it be better to stick to Windows Server 2008 or switch to Ubuntu?

View 9 Replies View RelatedI dual boot XP and FC14 and have 2 routers. I can connect and ping one of these routers when I'm in FC and I have an IP address I just can't load any websites. When I connect to the other router (my main router) it works fine. When I boot into XP and connect to the problem router I can load pages fine. It's only when I'm on FC14 and connect to the problem router that I can't load pages even though I have an IP and can ping around.
View 1 Replies View RelatedI plan to design a general framework for structural optimization.I already have a pre-processor module that I can call in batch mode, a Finite Elements Solver, and a heuristic non gradient based optimizer that can process the outputs of the solver, so as to adjust some input variables in the pre-processing phase ( geometry and topological definitions of my structure ).
I would like to parse the huge ammout of data that is released by the solver ( an ascii text file) to filter out some reauired results in some specific points ( maximum allowable deflections or stresses within my structure ) since it is this infoemation that will be fed to the optimizer engine so as to feedback on the quality of the changes made in the topological definition.The only way to do this in batch mode is with awk, or with sed..

View 1 Replies View RelatedI am using Linpus lite (a fedora based linux) on an ACER ONE notebook. I use a GUI to install/update or remove software. It is called pirut. I believe it a GUI of the yum command. The repository this install program uses is the fedora one. I find the following description of the repository in the menus of that GUI:
Name: Fedora Description:Fedora 8 - i386 Mirror list : h[URL]... The problem is the following: The versions I can install from that GUI are outdate. For example, the firefox I have is 2.0.0.14 although the newest one available at the firefox website is 3.6.8. The same with openoffice, gcc and many many other tools.
This is embarrassing: I wanted recently to install a software on my own which was not available at that repository. This software requires recent versions of many tools. It's embarassing to have to update them manually..
I assumed the default repository of fedora should have access to the newest versions. If that is true, then the problem is in my system and not in the repositories. In that case, does any one have a clue on how to fix that problem? Now if the repository I use is indeed outdated, Should I change to another repository? Can anyone indicate which repository is compatible with my system and how to add it?

View 1 Replies View RelatedI am familiar with C, C++, and Python at a novice level. I have recently tried learning bash, but I can't seem to wrap my head around it. My biggest problem, I think, is the huge "vocabulary"-- it seems like there are thousands of commonly used commands, and several ways to use said commands.I've done some google searches but can't seem to find scripting tutorials that tailor to n00bs. Most go from basic "Hello World" programs to very complex scripts.
View 5 Replies View RelatedI've been looking around the net for executing a shell script. My basic understanding is that after setting executable permissions and providing a path (#!/bin/sh) in the first line of the script, I can type ./myscript to execute instead of sh myscript. This is not working for me. I can run "sh myscript" but not "./myscript" even though I know for sure I have across the board execute permission and my sh path is correct. I'm working on a redhat linux station.
View 6 Replies View RelatedI want to automate the following manual process.Currently, I am encryptying a set of files using openssl as follows:Encrypt file.txt to file.out using 256-bit AES in CBC mode $ openssl enc -aes-256-cbc -salt -in file1 -out file1.enI am then prompted for a password, which is then used to encrypt the fileWhen decrypting, I type $ openssl enc -d -aes-256-cbc -infile1.enc -out fileI am then prompted for the password - which again, I manually type.I want to automate this process of en/decryption - so I need to find a way of providing openssh with the password.
My first thought is whether it is possible to read the password from a file (say)? Or is there a better way of doing this?Also, I suppose that I will have to place restriction on who can view the password file - otherwise, that defeats the whole objective of using a password. I am thinking to run the bash script as a specific user, and then give only that user read rights to the contents of that file.Is this the way its done - or is there a better way?Ofcourse all of this leads to yet another question - which is, how to run a bash script as another user - without having to type the user pwd at the terminal.
I think this goes here, but I'm not sure. I decided that XAMPP had been troublesome enough. MySQL never worked. So I decided to instal the LAMP stack offered by YaST. I went about installing it thinking that it would all work. But it seems that I was wrong. So I try to start mysql, and here's what I get:
