How to configure Jetty in GWT

[wille...@gmail.com]

Hi,

I've recently migrated from GWT 1.5.x to 1.7.0 and I'm looking for
pointers to articles/documentation/... on:
1) how to configure the JNDI lookup within Jetty (I want to define my
database connection details)
2) how to configure container managed security within Jetty

If the above are too specific, then maybe just how to configure Jetty
in general, within the GWT - eclipse environment.

Or should I venture down the -noserver path ?

Ciao,

W.

That I was never doing, I always use the Tomcat-server being
"shipped" with GWT. But installing a GWT-application is simply
adding the WAR-file to the web-app-directory or define it as
specific WebApplication.

Thanks for your answer, Lothar.

The info on jetty you provided I had already found. What I am actually
looking for is that specific info in the context of GWT 1.7,
So as to be able to use all the debugging features (as well client as
server code debugging) when running my gwt-app in eclipse, in hosted
mode using jetty as a server.

To rephrase my question: how do you configure jndi and container
managed security in the Jetty instance that comes along with GWT 1.7.

Ciao,

W.

Hi Christoph,

Thanks for the info, that was a real good starting point.

Also helpful where these posts:
http://humblecode.blogspot.com/2009/05/gwt-16-using-jndi-datasource.html
http://groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/3f5369b0aea1a265
http://groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/d37a823d8fac8693

I'm putting some advice and my configuration files here, they might be
useful to somebody.

First about about my webapp: it uses jndi to lookup a datasource, and
applies container managed security via JDBCRealm, all data is stored
in an Oracle database.
It was developed using GWT 1.5, and has a working Tomcat
configuration.

In the end of my conversion to Jetty, I didn't manage to get the
container-managed-security via JDBCRealm working because Jetty assumes
the ID's in the tables are ints (mine are varchar2s), so it throws the
java.sql.SQLException: Fail to convert to internal representation.
For development/debugging purposes a HashUserRealm is fine, and it's
very easy to setup.

----------------------------------------------------------------------
- I assume you have your oracle jdbc jar in your lib folder )
----------------------------------------------------------------------
- download jetty-6.1.19.zip, unzip and copy lib/naming/jetty-
naming-6.1.19.jar and lib/plus/jetty-plus-6.1.19.jar to your war/WEB-
INF/lib
----------------------------------------------------------------------
- add to your eclipse launch: (advice from
http://humblecode.blogspot.com/2009/05/gwt-16-using-jndi-datasource.html)
-
Djava.naming.factory.initial=org.mortbay.naming.InitialContextFactory
----------------------------------------------------------------------
- Put the security constraint and database resource ref in your war/
WEB-INF/web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app>
..
<servlet> .. </servlet><servlet-mapping>.. </servlet-mapping>
etc..
..
<security-constraint>
<web-resource-collection>
<web-resource-name>MyWebApp</web-resource-name>
<description>MyWebApp</description>
<url-pattern>/protected/*</url-pattern>
</web-resource-collection>
<auth-constraint>
<role-name>admin</role-name>
<role-name>user</role-name>
</auth-constraint>
</security-constraint>

<login-config>
<auth-method>FORM</auth-method>
<realm-name>MyWebApp</realm-name>
<form-login-config>
<form-login-page>/logon.jsp</form-login-page>
<form-error-page>/logonerror.jsp</form-error-page>
</form-login-config>
</login-config>

<resource-ref>
<description>My DataSource Reference For The Database</
description>
<res-ref-name>jdbc/myapp</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
..
<web-app>
----------------------------------------------------------------------
Define your database and security in the war/WEB-INF/jetty-web.xml

<?xml version="1.0"?>
<!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN"
"http://jetty.mortbay.org/configure.dtd">
<Configure class="org.mortbay.jetty.webapp.WebAppContext">

<New id="myapp" class="org.mortbay.jetty.plus.naming.Resource">
<Arg></Arg>
<Arg>java:comp/env/jdbc/myapp</Arg>
<Arg>
<New class="oracle.jdbc.pool.OracleConnectionPoolDataSource">
<Set name="URL">jdbc:oracle:thin:@localhost:1521:XE</Set>
<Set name="User">myapp_user</Set>
<Set name="Password">myapp_pwd</Set>
</New>
</Arg>
</New>

<Get name="SecurityHandler">
<Call name="setUserRealm">
<Arg>
<New class="org.mortbay.jetty.security.HashUserRealm">
<Set name="name">MyWebApp</Set>
<Set name="config">config/dev_realm.properties</Set>
</New>
</Arg>
</Call>
</Get>

----------------------------------------------------------------------
File: config/dev_realm.properties
bob:bob,admin

(yes, just one line with the username:password,role)
----------------------------------------------------------------------

And fire it up!

I still get a warning though, when starting up my app:
[WARN] Unable to process 'file:war/WEB-INF/web.xml' for servlet

I guess it's to do with the security configuration in the web.xml,
I'll look at it later.

Regards,

Willem
