Re: DB connection error and broken images while changing webapp context path
Hi Astghik, I don't really have a clue on your problem as I think you are creating a virtual host within your tomcat installation. What I do when I want to have myapp at the root directory of server (so you access it with http://myip:8080) is to install your application in webapps/ROOT instead of webaps/myapp. But maybe you wanted to achieve something else... In any case I think you should check your images are being properly accessed (use firebug or something alike) and see if the path being resolved for them make sense (note you have set www.myip.com as host pointing to myapp, localhost won't work as expected as it still points at webapps) Hope this helps... a little mabe :-) Cheers, Estani Astghik wrote: Hello All.

Re: DB connection error and broken images while changing webapp context path
And to create virtual host and to set my webapp as root dir. I've done both of them. But now I have db access problems and images on site don't display.

Re: DB connection error and broken images while changing webapp context path
HI Astghik 1. Don't put Context ... / elements in server.xml. They should go into files named ROOT.xml in /etc/tomcat6/Catalina/localhost and /etc/tomcat6/Catalina/www.myip.com. While your at it, drop the docbase and path attributes ... they aren't needed when the Context element is in it's own xml file. 2. Rename myapp in /var/lib/tomcat6/webapps from myapp to ROOT. ROOT is a special name for the default webapp and defined in the servlet spec. Between this and the first suggestion, both localhost and www.myip.com should be showing your myapp webapp as the default webapp (no /myapp in the url). 3. Don't point two host elements at the same appBase. Either have two separate appbases, one for each host and keep two copies of the webapp or use an Alias element and have only one Host ... element. See http://tomcat.apache.org/tomcat-6.0-doc/config/host.html for more information on the Alias directive. 4. I don't see anything here that has any impact on database connectivity ... actually don't see any database configuration here at all. Could you include some info on your hibernate setup for myapp? --David On 8/13/10 7:03 AM, Astghik wrote: Hello All. I have Apache Tomcat 6 server running on Ubuntu 9.10. .

Re: DB connection error and broken images while changing webapp context path
Astghik, As has already been pointed out: 1. Don't put Context elements in server.xml - use either: a. META-INF/context.xml in your web application b. $CATALINA_HOME/conf/Catalina/[hostname]/[application].xml 2. Don't use docBase in your Context element. Tomcat will figure that out 3. Don't use subdirectories of one appBase as the appBase for another host - this will probably get you double deployment. If you want your application to be known as both http://localhost:8080/ and http://my.ip.com:8080/ then you can do the following: 1. Rename your war file ROOT.war. This is the name used for the root application 2. Add an Alias element to your original Host element - something like this: Host name=localhost appBase=webapps unpackWARs=true autoDeploy=true xmlValidation=false xmlNamespaceAware=false Aliasmy.ip.com/Alias /Host From your path statements, it looks like you're using the default Ubuntu-distributed Tomcat (and maybe OpenJDK)? This has led to some problems in the past. I recommend downloading the latest tar.gz of Tomcat 6 (6.0.29) from tomcat.apache.org, and the latest version of Java (1.6.0_21) from Oracle/Sun for your platform. If you're having trouble getting Hibernate to work with Tomcat, and especially Tomcat's database connection pooling, you might want to see the following Wiki article: http://wiki.apache.org/tomcat/TomcatHibernate If you really are interested in virtual hosts rather than just an Alias, then you might want to see the following Wiki article: http://wiki.apache.org/tomcat/TomcatDevelopmentVirtualHosts Once you get all of this digested, then post your information (Tomcat server version - complete with minor revision numbers, JRE version, OS, server.xml with no comments and sensitive info blanked out, web.xml from your application, hibernate.cfg.xml, Spring configuration files, and where your images are located in your web application structure) if you're still stuck. Hope this helps. . . . . just my two cents. /mde/ - Original Message From: Astghik mkrtch@mail.ru To: users@tomcat.apache.org Sent: Fri, August 13, 2010 4:03:43 AM Subject: DB connection error and broken images while changing webapp context path Hello All.
