![I want to run java program in a web browser. I installed tomcat and eclipse. but i am getting an error "Starting tomcatv7.0 server at local host". How to solve this error? Please help me. I have attached the error page:
First check whether your TOMCAT_HOME\bin contains bootstrap.jar.
Second, go to your project build path and remove reference of bootstrap.jar and then try to run the application.
Regards,
Bipul Sinha
it seems that u need to put bootstrap.jar in your tomcat's bin folder.
upd
try to delete tomcat's configured server from eclipse and add newone
upd
goto Run -> Debug/Run Configuration -> Classpath tab and check your bootstrap.jar path is correct

Hi I already develop my application using Netbeans IDE.
Now I want to run my application in Tomcat server for actual use. I already copy my project to tomcat/webapps.
But when I tried to run my application:
http://localhost:8081/myAppFolder/
it gives me an error message :The requested resource (/Opportunities-Registration/) is not available.
I should change the url to make it work:
http://localhost:8081/Opportunities-Registration/web/index.jsp
How can I open my application using http://localhost:8081/myAppFolder/ insteand of http://localhost:8081/Opportunities-Registration/web/index.jsp ?
Update:
All my servlet is also become 404 not found
Thank you
SOLVED
Solution:
1. copy .war file which is contained in dist folder of your netbeans project
2. Place your .war file to tomcat/webapps
3. Start your tomcat
4. You are good to go
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 am developing a dynamic web application on JBoss developer, but I am getting an error message:
Could not load the Tomcat server configuration at
\Servers\Tomcat v6.0 Server at localhost-config. The Servers project
is closed.
Even when I try to start the server on the servers tab, it doesn't start.
Any suggestions?
Sounds to me as if you're doing this inside Eclipse with WTP?
If so then you need to make sure that the Eclipse project called Servers which is created and maintained by WTP is open.
Open the Navigator view
Locate the Servers project
right-mouse click
Open Project
You have been closed server project in eclipse which will come by default after adding tomcat into eclipse. So try to open server project and start Tomcat it will Work..
Steps:
Go to project explorer.
Double click on server project.
You installed Tomcat v6 within eclipse using the “Add server” wizard and the “download and install” button.
You tried to start Tomcat and got the following error:
****“Could not load the Tomcat server configuration at /Servers/Tomcat v6.0 Server at localhost-config. The configuration may be corrupt or incomplete”****
How to solve:
1) . Close Eclipse
2) . Copy all files from TOMCAT_6_HOME/conf to WORKSPACE_FOLDER/Servers/Tomcat v6.0 Server at localhost-config
3) . Start Eclipse
4) . Expand the Servers project, click on the Tomcat 6 project and hit F5
5) . Start Tomcat from Eclipse
6) . Enjoy!!!
Just after many trying I got the solution for this problem. The problem is when your server is created using your IDE(Eclipse, JBoss or any) that time the server is not getting the configuration file. To resolve this problem you need to copy all the configuration files from the tomcat conf directory to your IDE server directory. If I will step out the solution than I can list the steps as-
Locate your Tomcat installation directory
Find the conf directory, sometime you will get it into skel directory
Copy all the files from conf and now change the directory to your IDE workspace
In Server directory paste all the files in your Tomcat configuration directory.
If you are using a Linux-based Eclipse:
Check user and group ownership and permissions to your server directory and subdirectories inside Eclipse. It MUST allow read-write config files by the current Eclipse user. Test it copying config files directly to it and, after that, accessing it through Eclipse text/xml editor.
It's usefull too to check the same for tomcat directory, because Eclipse may be bloked if its owner doesn't have permissions to access that files.
the solution to this problem is :
cd /usr/local/tomcat//conf
chmod 777 *
and it's done
I got the same issue. This is because it's missing "Servers" folder that contains Tomcat in Project Explorer. I already downloaded and configured my Tomcat, but after I created another new java web project, Server stopped working.
To solve this problem right click on "Tomcat v6.0 Server at localhost
[Strated,Synchronized]"
at bottom of your Eclipse.
click "General"
click "Switch Location"
click "Apply"
enter image description here
This usually happens when the "Close unrelated projects" button is clicked. A simple and straightforward solution to this issue:
Go to the bottom of the Project Explorer tab and there will be a project named "Servers". If it's closed, the icon will have a different color than the projects that are open.
Double-click on "Servers". Now the project will be open and this issue will get resolved.
I have been working on a Java web application and i am using SmartGwt on Netbeans 7.3 and out of a sudden I encountered this problem. I tried cleaning the build-impl.xml then restarting the IDE and I should say I have fairly low knowledge on this. Can someone please tell me why it is giving an error and how I can fix that?
The error message says :
nbproject/build-impl.xml:1031: The module has not been deployed. See the server log for details.
BUILD FAILED (total time: 4 seconds)
Note: i am using Tomcat 7.0.34
may its so late but the response useful for others so :
Sometimes, when you don't specify a server or servlet container at the
creation of the project, NetBeans fails to create a context.xml file.
In your project under Web Pages, create a folder called META-INF.
Do this by right mouse button clicking on Web pages, and select:
New->Other->Other->File Folder
Name the folder META-INF. Case is important, even on Windows.
Create a file called context.xml in the META-INF folder.
Do this by right mouse button clicking on the new META-INF folder, and
select:
New->Other->XML->XML Document
Name it context (NetBeans adds the .xml)
Select Well-formed Document
Press Finish
Edit the new document (context.xml), and add the following:
<?xml version="1.0" encoding="UTF-8"?>
<Context antiJARLocking="true" path="/app-name"/>
Replace app-name with the name of your application.
Now your in-place deployment should work. If not, make sure that the
file can be read by everyone.
The context.xml file is specific to Tomcat. For more information about
that file, see the Tomcat documentation at tomcat.apache.org.
Start your IDE with administrative privilege( Windows: right click and run as admin), so that it has read write access to tomact folder for deployment. It worked for me.
Take a look at the server logs!
I had been with this for hours. The awful Tomcat servlet is not very helpful neither but if you can see the stacktrace that should be enough.
For instance, I read the following error message there:
As you can see, the message was pretty clear and easy to fix :-)
Check if there any other instance of the server is running already
Check if the port that will be used by the server is free.
If you add jars in tomcat's lib folder you can see this error
Close Netbeans.
Delete all libraries in the folder "yourprojectfolder"\build\web\WEB-INF\lib
Open Netbeans.
Clean and Build project.
Deploy project.
One of the main reason for this error is due to permission not granted to all users. so remove this error, follow the following steps :
1) Go to the C:/Programme Files/Apache Software Foundation/Tomcat 7.0
2) Right click on the Tomcat 7.0 folder and click on properties.
3) go to Security Tab.
4) Select the User and click on Edit... button
5) Grant all the permission to the user and click on apply and ok.
Refresh the system and now try. I hope it will work
if you still getting this error try this.
Go to Netbeans services
Remove Apache Tomcat.
Add Apache Tomcat again.
Build Project.
Deploy Project
in my case , it said that the 8080 port is in use , so I change the server port of Tomcat to 8081 and it works
Check whether you placed the within the .. or outside the ...
If you placed it outside the server tag , and if you try to access the init-parameter then it will give error.
I'm having a little problem configuring my Tomcat Project. In short, I'm working on a Dynamic Web Page project but there seems to be some confusion as to from where I am running the application.
Running the following code
File f = new File("");
System.err.println(f.getAbsolutePath());
yields the output C:/Eclipse which happens to be where I run Eclipse.
Normally I'd expect this to be the output catalog, but it is not the case this time.
My eclipse project is configured to have myProject/WebContent/WEB-INF/classes as output folder
How can I configure to the desired directory? Right now I need to use absolute paths which won't work for all members of the project.
Alright, I found a solution.
It seems my default working directory was set to my eclipse folder for the project so i solved it by specifying the project root folder instead which normally is the case.
I configured this here:
Run configurations > Apache Tomcat Run configuration > Arguments tab, under "working directory" choose "other" and specify directory.
Thanks for your comments!
