I am currently using the cloudfoundry eclipse plugin to deploy my JSP/Servlet web application. My application is now using a Db (Sqlite). However I am having problem deploying the sqlitejdbc.rar to cloudfoundry (all i do to update the application is right click on my application under VMware Cloud-foundry server and select update. But that doesn't seem to work and i get an exception saying that it cant find the rar file.
In my local system i simply paste the sqlitejdb.rar to the lib directory of Tomcat and when i run the webapp locally it works
If you place the sqlitejdbc.rar file into your lib directory (inside your WEB-INF directory) that should get deployed as part of your application into cloudfoundry and become accessible.
You can also try to deploy your app using vmc push to see what errors you get from vmc.
I also recommend looking at the log files on cloudfoundry.com

I uploaded myapp.war file to server using Tomcat Web Application Manager
It upload myapp.war file but does not list in List of application.
myapp.war file and myapp (unzipped folder) is inside wepapps folder but also not listed in Application list. It only shows the default applications only.
Then i tried to upload again the same file and got error file already exists.
Why is it not listing the app though it is deployed?
Had the same issue. Even though tomcat manager says app is deployed successfully, you might be able to find the relevant issues in the catalina log.
<tomcat_home>/logs/catalina.xxxx-xx-xx.log
I've recently found out how to remotely debug my java files on a Tomcat server via eclipse and was wondering something. I am wondering if I could import the same files into Eclipse that are currently housed in the webapps folder on my tomcat server, and instead of having to go to that filepath anytime I need to make a code change with the files in the tomcat server, be able to make them directly in Eclipse which I would be using to debug anyway.
Currently I've tried importing the same project folder from the webapps folder in Tomcat into Eclipse and made a small code change, relaunched my server, but am not seeing the change in my tomcat library.
When importing into Eclipse does it make it's own separate instance of the files, instead of actually being able to import the same exact files as in the tomcat server?
If you double-click the Tomcat server in the 'Servers' view inside Eclipse, you will see a configuration tab "Server Locations".
By default, eclipse doesn't make changes to the tomcat 'webapps' folder, it uses folders under its workspace.
Changing that option to 'Use tomcat installation' will make the changes be visible from the tomcat/webapps folder on your file system.
I am new in web development, please help about the uploading the java website on live server with mysql database.Please tell all the steps.
It you want to test your application on live server.
Try it with Jelastic, a free trial for 2-weeks which gives you better understanding on deploying and testing your java web application on live server.

If you are using JBoss Application Server 7, deploy your application over LAN network (deploy on 1 system and access from any other device)
Export your application in EAR or WAR from IDE
Just copy and paste you WAR/EAR file in deployment path like(D:\jboss-as-7.1.1.Final\standalone\deployments)
open cmd, change directory to bin folder of JBossAS7
Write command standalone.bat -b 0.0.0.0
Access your application like: http://192.168.1.9:8080/YourApplication

To deploy java on live server
firstly convert your java project to war file. Then rename it to root.war.Now open the tomcat manager provided by hosting service provider.Browse the root.war file and deploy it.
Secondly,for mysql db... Create mydb.sql file.Now go to your cpanel and create the database .And after that add the username and pass to myconnection utility java program.Now in cpanel go to phpmyadmin ,Click on the db created and import the mydb.sql created.And now you have successfully deployed the java project.
I am new to java web programming and eclipse-apache Tomcat. I have small login web-application which includes (one jsp page , one servlet class).
I want to configure/deploy this application on apache web application manager. I mean I don't want to run this application in eclipse. I hope you understand my point.
Whenever I run my server in eclipse it run successfully. But when I want to open apache default page by typing http://localhost:8080 or http://localhost:8080 to configure my app It wouldn't open.
Please advice me.
To deploy a web application on Tomcat, you need to first compile your web application into a WAR file. Then, take that WAR file (let's assume it's called "MyApp.WAR") and put that into the tomcat/webapps directory. Restart the tomcat service. Tomcat will extract that WAR to a folder in the webapps directory. After that, any request to localhost:8080/MyApp will go to your webapp.
Make sure you have java installed, and add JAVA_HOME to your environment variable. (it is the path to java installation directory for e.g. C:\Program Files\java\jdk-1.6)
i.e
JAVA_HOME=C:\Program Files\java\jdk-1.6
install TOMCAT from here "http://tomcat.apache.org/download-70.cgi"
make sure you do not install it in you "c:\program files" due to some permission issues.
Lets say you installed tomcat at "c:\webserver\apache-tomcat\" this is your CATALINA_HOME, add it to your environment variable
i.e CATALINA_HOME=c:\webserver\apache-tomcat\
to acess tomcat webapp manager you need to configure user in %CATALINA_HOME%\conf\tomcat-users.xml
Add a role and a user :
Have your WAR file ready with you (this is how you create WAR "How to make war file in Eclipse")
move your WAR file to "%CATALINA_HOME%\webapp" directory. lets say "TestWeb.WAR" is your application with index.jsp page in it.
Now go to your %CALALINA_HOME%\bin and launch the startup.bat file (you would be using startup.bat to start and shutdown.bat to stop tomcat)
once tomcat is up and running check http://localhost:8080 is working fine.
P.S. If port 80 is already in use then try configuring your tomcat to some other unused PORT here "http://www.mkyong.com/tomcat/how-to-change-tomcat-default-port/"
go to your browser type http://localhost:8080/TestWeb/index.jsp
now you can to lot of configuration to your web app like having a default page and all
Hope this help you !
Normally eclipse uses Tomcat as an eclipse project, hence it uses metadata.
Server > Double click on the tomcat server instance > Server Location > Select "Use Tomcat installation"
Update: Tested just now. Set Deploy path to webapps folder. Works fine :)
I have a website someone's developing for me on a VPS (Java, javascript, CSS, HTML) that I would like to run on my Macbook Pro.
He commits the source on Github, which I download with Sourcetree.
I have Tomcat 6 and MySQL running on the Macbook fine.
Can I bring the root folder, the mySQL db and an associated media folder over without creating a .war file to run it on tomcat on localhost by simply setting up the connections properly in datanucleus, or is it much more complicated than that?
Thanks in advance for your thoughts.
I know people who try to develop application directly in die Webapp Folder from Tomcat but that is not the right way.
At your place i'll do this:
clone the application locale on your mac
Use an IDE(eclipse/Netbeans/IntelliJ) to open the project
Build a local war file which you can deploy directly to your $CATALINA_HOME/webapp/
Do not forget the make all required mySQL settings (context.xml) and so on...
Yes, you can. But it is necessary to have compiled webapp.
Simply put root folder contents (your deployed application) to "/webapps/ROOT" and start tomcat by running script in "bin" folder.
Make sure that you properly configured database properties of your application.
If you have only sources - it is not such simple. You have to build war and deploy it. Or ask developer to include "target" directory in git repository and then copy "classes" folder to /webapps/ROOT/"
