SWT Browser requires a compatible xulrunner version installed

error:

GWT Designer uses the SWT Browser widget to render the GWT UI. SWT
Browser requires a compatible xulrunner version installed: it should
be 1.9.1.x or 1.9.2.x version and meet the current environment
architecture. See http://www.eclipse.org/swt/faq.php#whatisbrowser and
related topics for more information. 

solution:

1 - Download eclipse from eclipse.org. 

http://www.eclipse.org/downloads/packages/eclipse-classic-372/indigosr2
(DO NOT USE UBUNTU REPOSITORY.)

https://developers.google.com/eclipse/docs/download

2 - After installation, start Eclipse and disable the option

 "Use webkit rendering window for GWT UI if available", at Window, Preferences, Window Builder,

 GWT

3 - Install the following two libraries in the following order, which will replace the webkit: 
sudo dpkg-i packagename.deb

download and install:
https://docs.google.com/file/d/0B9KWSpNWygKAYW1yeDhBa2xaRlU/edit# 

(filename: libhunspell-1.2-0_1.2.11-1ubuntu1_i386.deb ) 

download and install:

Running multiple tomcat servers

Download tomcat, and unpack it twice, into two separate directories. Edit the conf/server.xml file in one of the copies in the following way: Change the port on the root Server element to a different number (e.g. 8006) Change the port attributes on the Connector elements to a different number (e.g. 8010 instead of 8009, 8081 instead of 8080 and 8444 instead of 8443) You should now be able to run the bin/startup.sh scripts in both installations to get two running tomcats. Connect using port 8080 and install the basic application services, and then connect using port 8081 to install the service provider management services. Source link. Some other useful links are given links, links.

creating the hosts in the tomcat server in ubuntu

creating the hosts in the tomcat server in Ubuntu


step1:  In the /var/lib/tomcat6/conf/Catalina path we create folder with hostname 
           example: 'restarant'


step2: In that folder we create the file with name  'ROOT.xml'
           /var/lib/tomcat6/conf/Catalina/restaurant/ROOT.xml


step3: put following code in the ROOT.xml file

           <?xml version='1.0' encoding='utf-8'?>

           <Context displayName="hostname" docBase="/var/lib/tomcat6/webapps/warfilename/"                                                path=""  workDir="work/Catalina/hostname/_">

          </Context>

            example :

           <?xml version='1.0' encoding='utf-8'?>

           <Context displayName="restaurant" docBase="/var/lib/tomcat6/webapps/Restaurant/" path=""

           workDir="work/Catalina/restaurant/_">

          </Context>

step4:  In the /var/lib/tomcat6/conf/server.xml file  host tag(<Host>) data will be re paste in the file after close the host tag(</Host> and change the data in the 

example:

<Host name="hostname"  appBase="webapps/warfilename/"
            unpackWARs="true" autoDeploy="true"
            xmlValidation="false" xmlNamespaceAware="false">

        <!-- SingleSignOn valve, share authentication between web applications
             Documentation at: /docs/config/valve.html -->
        <!--
        <Valve className="org.apache.catalina.authenticator.SingleSignOn" />
        -->

        <!-- Access log processes all example.
             Documentation at: /docs/config/valve.html -->
        <!--
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log." suffix=".txt" pattern="common" resolveHosts="false"/>
        -->

      </Host>

step5: in Filesystem/etc/hosts file add the hostname and localhost port like
example:  127.0.0.1 restaurant


step6: restart the server

step7: In browser enter url like
example:  http://restaurant:8080/(hostname:portnumber)
