I have added tomcat 7 to my eclipse.
When I start the server it gets started successfully(shows the message in console) but when I hit the URL http://localhost:8080 it says "404 resource not found".
Strange thing is when I go to Tomcat bin directory and start it through start.bat, the same url http://localhost:8080 shows the tomcat homepage in browser without any issue.
Any idea? Help is appreciated.
You need to be aware of two directory trees with Tomcat : TOMCAT_HOME and TOMCAT_BASE.
TOMCAT_HOME contains binary related data and can be shared by many running Tomcat instances (it contains jar, dll, exe and other non-contextual data).
TOMCAT_BASE specifies configuration files (ie catalina.properties, server.xml, context configurations), webapp directories and further files such as specific librairies if required.
When running Tomcat from his installation directory: TOMCAT_HOME and TOMCAT_BASE are set to same location. Then, Tomcat serves ${TOMCAT_HOME}\webapps directory. The special ROOT context let serve the root path and by default contains a simple webapp (browse ${TOMCAT_HOME}\webapps\ROOT for more information).
When running Tomcat from Eclipse, Eclipse will setup two directories:
with editable configuration (generally goes under ${WORKSPACE}\Servers\${SERVER_NAME}-conf)
with deployed files from last describe directory, served context configuration, deployed context and some other working files such as log and work directories.
This last directory generally goes under your workspace metadata but you can edit it from the server editor. And Eclipse uses this directory as TOMCAT_BASE. To this directory, Eclipse doesn't deploy the default ROOT webapp neither other default ones (docs, examples, host-manager and manager). If necessary you can add them from the server configuration directory (first one described).
We have tomcat 7.0.55 in our unix server. We have deployed web applications manually inside webapps folder of tomcat instance. By default the clusterinfo.1200.properties and log4j logs are stored in .businessobjects folder under home directory of the user account in which tomcat runs.
While accessing the InfoView web application we get the below error,
"AccessControlException:"java.io.filePermission:Access Denied \home\<user account of tomcat>\.businessobjects\clusterinfo.properties"
Tomcat 7 has restriction to access the file outside the tomcat directory on the first logon. However on refreshing the page we are able to access the application.
I have tried the following steps.
stopped the tomcat instance
Moved .buisnessobjects from home directory to inside tomcat installed directory.
Created symlink as .businessobjects in home directory to point to the folder inside tomcat directory.
Started the tomcat instance.
It works. But I need to know where the configuration change has to be made in web application to place the clusterinfo property file and log4j file inside tomcat directory.
I am a novice in Java. Please let me know the file and its location to make this changes.
Desperately looking for a solution :-(
Did you try to grant more permissions on this file with chmod.
The exception explicitly says that its java.io.filePermission. So the problem is that jvm can't read your properties file because your OS prevents it from doing so based on the file permissions.
You can see file permissions with ls -l filepath.
I vaguely remember that you had to change owner of the accesed files in order for tomcat to work so chown tomcat7 \home\<user account of tomcat>\.businessobjects\clusterinfo.properties wouldn't hurt, but I don't remember if it was only applicable to deployed artifacts like *.war files or such.
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.
I previously used the following to get my context path on Tomcat-5.0.28 and earlier:
String context_path = context.getRealPath("/WEB-INF/");
This worked to return the path to that folder.
But on OpenShift (Tomcat 6 - JBoss EWS 1.0) this returns
/var/lib/openshift/53.*context_id_here*..18/jbossews/null
The null should be:
work/Catalina/localhost/_/WEB-INF
How can I get the path to the WEB-INF folder on OpenShift using JBOSS/Tomcat?
A little background information: When I ran this struts webapp on my own Tomcat server, I deployed a appname.war file in the webapps directory and waited for it to expand (since I had set that option in the server.xml file). Then I move a folder to webapps/appname/ folder with xml files I need to read and write to for my app to work. On OpenShift I used jar xvf appname.war to extract the war file by hand (because that's the default and I don't know how to change it), and then moved the files folder (from the same directory as the war file in my folder after a git add and push) to work/Catalina/localhost/_/WEB-INF/
This is causing a NullPointerException for me when trying to use that path as shown above.
I think you should be using something like getServletContext or getRealPath, and reading it from the web root instead of trying to find the file on the physical disk. That way your war file can run anywhere without issue. Try looking up both of those and see if one fits your use case.
I have this folder under Tomcat webapps/mysite which is where all my JSPs and other things are located. To access this folder I go to http://blah.com/mysite and it works just fine. However (because of stylesheets and images statically connected to the root /) I have to make it so that when I go to http://blah.com/ it will load the stuff inside webapps/mysite.
I've tried many different things including contexts and setting the absolute path in server.xml... nothing seems to work, whenever I go to http://blah.com/ it still tries to load the ROOT folder... what's happening here?
The solution I use is to set this in your Tomcat server.xml
Add a <Context> element within the <Host> like below which sets your mysite as the default web app. Note the empty path="" which makes it the default.
<Context docBase="mysite" path="" />
Attributes of Context Container from the Tomcat docs:
docBase You may specify an absolute pathname for this directory or WAR file, or a pathname that is relative to the appBase directory
of the owning Host.
path All of the context paths within a particular Host must be unique. If you specify a context path of an empty string (""), you are
defining the default web application for this Host, which will process
all requests not assigned to other Contexts.

There are a number of ways to make an application the root application. The simplest way is to just replace the contents of webapps/ROOT with the contents of your web application.
For other solutions, please see the following website:
http://wiki.apache.org/tomcat/HowTo#How_do_I_make_my_web_application_be_the_Tomcat_default_application_.3F
https://stackoverflow.com/users/1123501/george-siggouroglou 's awnser works but lacks a step.
delete ROOT and all items
copy the war to webapps as ROOT.war
Without the deletion, it may not work. Tested with docker.
You can rename your war from something.war == to ==> ROOT.war.
So, tomcat will unpack the war and will create the folder ROOT for it.
It is a trick that is working on tomcat 8 also.
