Tomcat : Context path not being set - java

I have a web app set up and running on Tomcat 8 with the project WAR file in the webapps folder in the tomcat directory. If i use any of the following links my project works fine
http://localhost:8066/myWebApp/home/
http://localhost:8066/myWebApp/booking/
http://localhost:8066/myWebApp/contactUs/
i want to set it so the above URL's work but also the following URL's which have /app added after the project name
http://localhost:8066/myWebApp/app/home/
http://localhost:8066/myWebApp/app/booking/
http://localhost:8066/myWebApp/app/contactUs/
i have set the path in the context.xml file as seen below
<Context docBase="myWebApp" path="/app" reloadable="true"> ... <Context>
but this does not work. am i doing this wrong or how can i go about doing this?
EDIT :
I can do this in eclipse by going to the server tab, opening the server and looking in the modules tab, so how do i do this on the Tomcat itself

You maybe use UrlRewriteFilter:
1. Add dependence
2. Change web.xml
3. Set rule in WEB-INF\urlrewrite.xml
or Rewrite.

How to Remove Project name from eclipse url?

Basically I want to remove project name while I access my project in eclipse.
so currently when I want to access a link of my web-app I have to put it as localhost:8080/project_name/blah_blah_blah
But I want it accessible by just localhost:8080/blah_blah_blah
or say The project itself should be accessible by just localhost:8080
.
Through googling I found this URL issue with tomcat include project name but in my case my context root is as / by default.
Project Context root Options
FYI: This is the only project I have in my Eclipse
For people who come across this problem too.
To explain deeply: First remember that eclipse uses server under eclipse project explorer within its all configuration.
In order for you change your project path to something different, what you can do is to open server.xml under Project Explorer -> Servers -> Tomcat vX.X ... -> server.xml.
At the bottom of this file You should see this line Before End of </host Tag:
<Context docBase="Duck" path="/Duck" reloadable="true" source="org.eclipse.jst.jee.server:Duck"/>
Notice: My project Name is Duck.
Now in order for you to access your web-app without project name replace path="/Duck" to just path="/" or You can set it to any name you want.

How to access folder in tomcat server using relative path of it?

I have one folder which has some PDF files which is used by my application, but when I include this folder in my war file , the size of war file increase to GBzz , so I thought of keeping this folder in some server location , build and deploy the war without the folder which will have the relative path of this folder , can any one help me on this? I am not sure how to do configuration for this to read the folder ?I am using tomcat server.
The easiest way starting from Tomcat 7 is to configure alias paths i.e. paths on the disk that will be aliased in Tomcat. Check this section in the guide for aliases attribute.
You want something like this in your server.xml:
<Context docBase="AppName" path="/appname" aliases="/pathPdf=c:\pdfs"/>
In case you're on an older Tomcat, your best bet is to setup a servlet that will serve files from the desired external location.

How to setup JNDI resource in tomcat with IntelliJ IDEA

I'm new to IntelliJ IDEA and I'm trying to set up JNDI resource in Tomcat but I'm using intelliJ IDEA. I have done this with Eclipse many times, but as you know there is a separate folder Servers in the project structure that allows you to open the server.xml and set up the JNDI resource. I've looked through the options of Tomcat in IDEA but couldn't find anything. Could you please help me?
You can just edit server.xml file in TOMCAT_HOME/conf/ directory, where TOMCAT_HOME is the directory of the Tomcat installation you have configured in Run/Debug configuration.
You can open and edit that file in IntelliJ using File/Open or just edit it outside of the IDE using vim for instance.
Project Structure > Module > Web > Click -> Add Application Server

Deploy JSP webproject to tomcat [duplicate]

I have copied the sample.war file into the webapps directory of Tomcat, and I can access localhost:8080.
Now how will Tomcat deploy it, I mean do I need to open it in browser? How can I access the application?
You can access your application from: http://localhost:8080/sample
Deploying or redeploying of war files is automatic by default - after copying/overwriting the file sample.war, check your webapps folder for an extracted folder sample.
If it doesn't open properly, check the log files (e.g. tomcat/logs/catalina.out) for problems with deployment.
step-1. here I'm deploying pos.war First go to tomcat webapps folder and paste it
step-2. go to tomcat->bin folder start tomcat by clicking startup.bat
step-3. go to browser write localhost:port/project name eg. localhost:8080/pos (here my tomcat run on port 8080)
Done....
You just need to put your war file in webapps and then start your server.
it will get deployed.
otherwise you can also use tomcat manager a webfront to upload & deploy your war remotely.
Manual steps - Windows
Copy the .war file (E.g.: prj.war) to %CATALINA_HOME%\webapps ( E.g.: C:\tomcat\webapps )
Run %CATALINA_HOME%\bin\startup.bat
Your .war file will be extracted automatically to a folder that has the same name (without extension) (E.g.: prj)
Go to %CATALINA_HOME%\conf\server.xml and take the port for the HTTP protocol. <Connector port="8080" ... />. The default value is 8080.
Access the following URL:
[<protocol>://]localhost:<port>/folder/resourceName
(E.g.: localhost:8080/folder/resourceName)
Don't try to access the URL without the resourceName because it won't work if there is no file like index.html, or if there is no url pattern like "/" or "/*" in web.xml.
The available main paths are here: [<protocol>://]localhost:<port>/manager/html (E.g.: http://localhost:8080/manager/html) and they have true on the "Running" column.
Using the UI manager:
Go to [<protocol>://]localhost:<port>/manager/html/ (usually localhost:8080/manager/html/)
This is also achievable from [<protocol>://]localhost:<port> > Manager App)
If you get:
403 Access Denied
go to %CATALINA_HOME%\conf\tomcat-users.xml and check that you have enabled a line like this:
<user username="tomcat" password="tomcat" roles="tomcat,role1,manager-gui"/>
In the Deploy section, WAR file to deploy subsection, click on Browse....
Select the .war file (E.g.: prj.war) > click on Deploy.
In the Applications section, you can see the name of your project (E.g.: prj).
In addition to the ways already mentioned (dropping the war-file directly into the webapps-directory), if you have the Tomcat Manager -application installed, you can deploy war-files via browser too. To get to the manager, browse to the root of the server (in your case, localhost:8080), select "Tomcat Manager" (at this point, you need to know username and password for a Tomcat-user with "manager"-role, the users are defined in tomcat-users.xml in the conf-directory of the tomcat-installation). From the opening page, scroll downwards until you see the "Deploy"-part of the page, where you can click "browse" to select a WAR file to deploy from your local machine. After you've selected the file, click deploy. After a while the manager should inform you that the application has been deployed (and if everything went well, started).
Here's a longer how-to and other instructions from the Tomcat 7 documentation pages.
There are two ways:
Either you can do hot deployment (Hot deployment means deploying when server is running/up).
Or you can do cold deployment (Cold deployment means deploying when server is stopped).
Just use tomcat manager console for console deployment or simply copy and paste your application in webapp folder of your server's tomcat_home directory.
Note: Make sure if your war file size is more than 52 MB (the default configuration value),
you need to make two little changes in web.xml file of Manager application of your webapp folder(Manager application is provided by Apache tomcat by default upon installing the server).
Go to the web.xml of the manager application (for instance it could
be under /tomcat7/webapps/manager/WEB-INF/web.xml.
Increase the max-file-size and max-request-size values in web.xml file:
<multipart-config>
<!– 50MB max –>
<max-file-size>52428800</max-file-size>
<max-request-size>52428800</max-request-size>
<file-size-threshold>0</file-size-threshold>
</multipart-config>
Increase the size by putting the values for <max-file-size> and <max-request-size> according to your requirement.
This has been working for me:
Create your war file (mysite.war) locally.
Rename it locally to something besides .war, like mysite.www
With tomcat still running, upload mysite.www to webapps directory.
After it finishes uploading, delete the previous version mysite.war
List the directory, watching for the directory /mysite to disappear.
Rename mysite.www to be mysite.war
List the directory, watching for the new /mysite to be created.
If you try uploading the new file as a war file, with tomcat still running, it will attempt to expand it before it is all there. It will fail. Having failed, it will not try again. Thus, uploading a www file, then renaming it, allows the whole war file to be present before tomcat notices it.
Hint, don't forget to check that the war file's owner is tomcat (Use chown)
If you installed tomcat7 using apt-get in linux then, deploy your app to /var/lib/tomcat7/webapps/
eg.
sudo service tomcat7 stop
mvn clean package
sudo cp target/DestroyTheWorldWithPeace.war /var/lib/tomcat7/webapps/
#you might also want to make sure war file has permission (`777` not just `+x`)
sudo service tomcat7 start
Also, keep tailing the tomcat log so that you can verify that your app is actually making peace with tomcat.
tail -f /var/lib/tomcat7/logs/catalina.out
The deployed application should appear in http://172.16.35.155:8080/manager/html
For deploying the war file over tomcat,
Follow the below steps :
Stop the tomcat. powershell->services.msc->OK->Apache Tomcat 8.5->stop(on left hand side).
Put the .war file inside E:\Tomcat_Installation\webapps i.e. webapps folder i.e. put.war (put.war is just an example)
After starting the tomcat(to start tomcat powershell->services.msc->OK->Apache Tomcat
8.5->start )
you will get one folder inside E:\Tomcat_Installation\webapps**put**
In this way you can deploy your war file in Apache Tomcat.
1.Generate a war file from your application
2. open tomcat manager, go down the page
3. Click on browse to deploy the war.
4. choose your war file.
There you go!
The application name goes into the context of your tomcat deployed URL,
eg. http://localhost:Port/applicationName.
If your application name is simple then, it should be http://localhost:8080/sample.
By default, Port is 8080, but if you wish to change it, or want to know the port where tomcat is running, simply go to server.xml file in <tomcat-apache-dir>/conf/server.xml, there you can find port & change,
eg. <Connector port="8080" redirectPort="8443" connectionTimeout="20000" protocol="HTTP/1.1"/>
If anything goes wrong, check the log files (e.g. <tomcat-apache-dir>/logs/catalina.out)
Perform the following steps:
Stop the Tomcat
Right Click on Project and click on "Clean and Build"
Go to your project Directory and inside Dist Folder you will get war file that you copy on your tomcat
webApp Folder
Start the tomcat
automatic war file extract and run your project
I followed the instruction in the following link, it works for me.
http://www.coderanch.com/t/487178/Tomcat/war-file-show-load
Stop Tomcat
Delete all the logs in tomcat/logs and all files in tomcat/conf/Catalina/localhost
Remove the war file and the directory it created (if it did) from tomact/webapps
Start Tomcat
While watching the logs, copy the war file to the webapps directory again
After this, keep an eye on the catalina.xxxx-xx-xx.log to find out the issue.
