Re: GWT 1.7 + Datasource
After some searching I found this: http://humblecode.blogspot.com/2009/05/gwt-16-using-jndi-datasource.html . It worked for me on GWT 2.0 + MySQL. Be careful when copy-pasting the sample jetty-web.xml file, it uses "curling quotes"; also, don't forget to add jetty-plus-*.jar and jetty-naming-*.jar to the build path (read the post's comments for more info).

Re: GWT 1.7 + Datasource
I am also very interested in this capability. After spending this entire day researching the question and then attempting various combinations of code in web-jetty.xml configuration files I am not convinced it is possible yet. I have succeeded in deploying gwt code built using the instantiations plug-in to a glassfish server and accessing a mysql database. However, I would like to have the analogous capabilitiy on my development platform -- hence the need for the gwt hosted mode server (jetty) to be able to access datasources. The current version of jetty distributed with the latest gwt (1.7.1) hosted mode is jetty 6.1.11. This version of jetty apparently did not incorporate jdbc support. Rather, jdbc capability was distributed separately in another package (jetty.plus...?) for 6.1.11. It appears that jetty 7.0 (which has migrated over to the eclipse foundation for future development) does incorporate a jdbc capability as part of its core distribution. But this version of jetty is not available (yet) as part of gwt. So it looks like we wait for gwt to upgrade to jetty 7.0. If someone has another idea for how to get the gwt hosted mode server to recognize and connect to datasources (specifically mysql), I'm all ears.

GWT 1.7 + Datasource
I am trying to implement a Datasource with the hosted mode server. This has turned out to be very confusing. The otherwise excellent book 'GWT in Practice' make reference to a Tomcat lite directory structure which I am unable to find. Other references in this group seem to point at Jetty but I can't really find a jetty launcher script. I should note that I am using the Instantiations Eclipse plugin but I doubt that this plays into the runtime configuration. I am looking for a context.xml file but cannot lcate anything besides the basic web.xml. I can make JDBC calls (JavaDB) via embedded and network driver just fine but establishing a connection every time seems the wrong way to go (am I mistaken). Instead I wanted to use connection pooling with a Datasource as I would in a production environment. Looking at some of the posts I am not the only one with this desire but can't seem to find an answer that appears fitting. Note that I am familiar on how to configure a Datasource in Tomcat but the embedded server seems to work in mysterious ways ;-). Any pointers on how to get this accomplished appreciated. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
