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]...
I 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 installed Tomcat (apt-get install tomcat6 tomcat6-admin tomcat6-common tomcat6-user tomcat6-docs tomcat6-examples) and it runs without problems.
I installed MySQL (apt-get install mysql-server) and it seems to run without problems too.
I changed the default JRE (update-java-alternatives -s java-6-sun).
The weird thing is - if I put the connector-jar into my web application (WEB-INF/lib), the connection works. If I put the connector-jar into usr/share/java, it does not work. If I write the jar location into the CLASSPATH and try "java com.mysql.jdbc.Driver", I get a NoSuchMethodError:Main, which means, that the jar is found?!
The datasource in the tomcat context.xml is:
<Resource name="jdbc/myresource" auth="Container" type="javax.sql.DataSource" maxActive="100" maxIdle="30" maxWait="10000" username="username" password="password" driverClassName="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost:3306/myschema" />
How can I make the database connection work without putting the jar into the WEB-INF/lib folder of the web application?
I got assigned to a project, where the installation is done over ansible. As I'm new in linux, python, django, ansible I wanted to try this out on a empty linux debian.

When I now run my ansible playbook it tries to install mysql and suddenly I get an error:

I use ubuntu lucid lynx, LAMP (mysql 5.1 and last php) and tried to install the package from mysql web page (mysql-connector-odbc-5.1.7-linux-glibc2.3-x86-32bit.tar.gz) through alien. Terminal output is as follows:p { margin-bottom: 0.21cm; }

what is the problem?
What I am doing is reading the text from a text document and storing all of the text inside of a ArrayList. I then set one of the values of the Arraylist as a string. I want to use regular expressions find out what the first two characters of the String are. if first two characters = "//" then function(); I only care about the first two characters though. If you need any more information, just ask.

View 1 Replies View RelatedI 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.

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:

Groovy is an object-oriented programming language for the Java platform. I do not have experience in Java, only perl and shell scripts. Recently I have been asked to maintain a software written in groovy (also to make enhancements). So can I learn groovy without knowing java language. or isit I have to learn java before venturing into groovy.

View 1 Replies View RelatedI am trying to use "find" but I can't quite get all of the switches right for it to work. I have a folder that contains many folders. Let's call that original folder "MyFiles". The subfolders contain java files (and those subfolders possibly contain subfolders that contain java files). Here is what I want to have happen:
0. Create a file to print to, call it "output.ps"
1. Find all of the Java files in the MyFiles tree.
2. For each java file that is found, append it to output.ps along with it's absolute path name.
So far I have:
find . -iname *.java
and this finds all of the java files for me. But then I can't get the files to print to a file using exec.

The problem is that the default lucid apt-get repositories do not contain the Sun's official distribution like Jaunty's does. Is there any way to get the official Java distribution on lucid (not sure how the others measure up) or is it just not officially supported?

I installed ubuntu 10.10 on a desktop to use for a media server, and plus some. Everything worked! I proceeded to install the nVidia driver for the 9800gt After it was installed I rebooted per the notification after installation.So now my computer loads directly into terminal and I can't start the GUI. I tried startx but it gave that whole warning about the "nopowerconnectorcheck".
So I've done my research and I bought a 650w psu. Still no dice. I know that there is a way to turn off the power connector check but I have no Idea how.

View 5 Replies View RelatedI have the following spec:
- Intel Core 2 Duo 1.86Ghz
- 4GB Ram
- 1TB Hard Disk
- 256MB Nvidia GeForce Graphics Card
I believe my system is quite fast, yet programs like JDownloader and Vuze (aka azureus) are very slow. More so on the GUI side, not so much program functionality (although I have not tested this either). If I scroll down a list of items, it takes ages, it lags and response time is quite bad.Also, I have two java processes running, each using 200MB of memory. I am assuming one is for Vuze and the other is for Jdownloader. It seems to me that Windows XP/Windows 7 ran java applications much faster and had less ram. I definitely see that with Vuze as it never went into the 200MB area when under windows.
