Increase Tomcat Upload File Size Limit

Today while deploying xyz.war file (development site code) in Tomcat (version 7.057), I faced following issue regarding upload limit size in Tomcat.

Caused by: org.apache.tomcat.util.http.fileupload.FileUploadBase$SizeLimitExceededException: the request was rejected because its size (128382112) exceeds the configured maximum (104828800)

Increase Tomcat Upload File Size Limit

To increase upload size limit in tomcat edit webapps/manager/WEB-INF/web.xml configuration file and search for below content.

# cd /path/to/tomcat
# vim webapps/manager/WEB-INF/web.xml

  <multipart-config>
  
      <max-file-size>52428800</max-file-size>
      <max-request-size>52428800</max-request-size>
      <file-size-threshold>0<</file-size-threshold>
   
  </multipart-config>
  

Edit max-file-size and max-request-size and increase it as your requirement. These values are defined in bytes and the default value is set to 50Mb.

After making all above changes, You need to restart Tomcat instance.

Hot to Install lamp in Ubuntu 12.04,12.10, 13.04, 13.10,14.04,14.10 & LinuxMint 13

LAMP (Linux, Apache, MySQL and PHP) is an open source Web development platform that uses Linux as operating system, Apache as the Web server, MySQL as the relational database management system and PHP as the object-oriented scripting language.

We did show you in our previous post how to install LAMP in Ubuntu 10.04 with one command using tasksel command. It is a software installation application that is an integral part of the Debian installer and works under Ubuntu Linux too. It groups some packages by tasks and offers the user an easy way to install the packages for that task. It provides the same functionality as using conventional meta-packages. in Maverick this command dosn`t come by default, so we need to install it first before to perform the LAMP installation.

This tutorial was has been tested on Ubuntu 10.04, 10.10, 11.04, 11.10, 12.04 LTS Precise Pangolin. Also tested in LinuxMint13 and works fine.

Open terminal and Type the command :install it first with

sudo apt-get install tasksel
sudo tasksel

Now to install LAMP, type the taskel command in terminal :

And select LAMP Server:

During the installation you will be asked to insert the mysql root password

Now check if php is working :

$sudo vi /var/www/info.php

save and exit. Restart apache2 ,

#sudo /etc/init.d/apache2 restart

Now open browser and type :

http://ip/info.php or http://localhost/info.php

Php is installed.

To full manage your lamp Server database, install phpmyadmin

sudo  apt-get  install  phpmyadmin

To login to phpmyadmin, open browser and type :

http://ip/phpmyadmin   or http://localhost/phpmyadmin
