!!! About Spring-rcp [#1]

The goal of the [spring-richclient project|http://www.springframework.org/spring-rcp] is to provide a viable option for developers that need a platform and 'best-practices' guide for constructing professional Swing applications quickly.

At line 18 added 1 line.

My work is based on the Spring-rcp Pet Clinic Demo (in [CVS|http://sourceforge.net/cvs/?group_id=113660] only) and my efforts in integrating it with Appfuse.

At line 10 removed 2 lines.

At line 23 added 275 lines.

!!! Configuring Appfuse - map servlet to be listening on "ws/*" url address [#2]

Add this portion of code to metadata/web/__servlets.xml__

{{{

<servlet-name>ws</servlet-name>

<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

<load-on-startup>2</load-on-startup>

</servlet>

<!--

- Dispatcher servlet mapping for HTTP web services.

- (see ws-servlet.xml for the controllers).

-->

<servlet-mapping>

<servlet-name>ws</servlet-name>

<url-pattern>/ws/*</url-pattern>

</servlet-mapping>

}}}

</div>

!!! Configuring Appfuse - create ws servlet[#3]

Create a ws servlet XML beans descriptor. Because I am using [Hessian|http://www.caucho.com/hessian/] instead of [Burlap|http://www.caucho.com/burlap/burlap.xtp] I have commented out Burlap-specific portions of the code. If you ever want to use Burlap instead just uncomment this part of the code.

The main difference between Hessian and Burlap is that Hessian is binary and Burlap is XML-based.

!!! Configuring Appfuse - add *.jar library dependencies [#4]

For more details read [how to add a library into appfuse|http://raibledesigns.com/wiki/Wiki.jsp?page=AppFuseAddLibrary] here.

Copy hessian.jar to appfuse/lib/hessian/hessian.jar

In lib/lib.properties add path info:

{{{

#

# Hessian

#

hessian.version=0.1

hessian.dir=${lib.dir}/hessian-${hessian.version}

hessian.jar=${hessian.dir}/hessian-${hessian.version}.jar

}}}

</div>

If you will ever need burlap do the same with the burlap *.jar files.

Add to __build.xml__ the hessian library dependency:

{{{

<target name="package-web" ......

.......

......

......

</target>

}}}

</div>

(properties.xml does not need any changes)

!!!Configuring Appfuse - add interface to allow remote client logins[#5]

Add this bean to web/WEB-INF/__applicationContextSecurity.xml__:

{{{

</bean>

}}}

</div>

!!! Configuring RichClient - source code[#6]

Download the [Appfuse Rich Client source code|http://raibledesigns.com/wiki/attach?page=RichClient%2Fappfuse-richclient.zip] and copy them to your Appfuse project.

%%note __NOTE__ At first I tried to create a new standalone project that referenced the Appfuse project but was independent from it. Unfortunately I had some issues with compilation so I decided to integrate it directly to the project.%%

!!! Configuring RichClient - libraries [#7]

You will need to download these jar archives and add them to the Eclipse classpath (Eclipse: Project/Properties/Java Build Path/Libraries/Add JARs). Be sure not to forget to refresh the appfuse directory structure afterwards.

{{{

appfuse/lib

/caucho

(84 871) burlap.jar

(83 245) hessian.jar

/jgoodies

(85 502) forms.jar

(338 486) looks.jar

/spring-rcp

(366 615) spring-richclient-resources.jar

(59 691) spring-richclient-sandbox.jar

(736 813) spring-richclient.jar

</div>

My collection of JAR files can be downloaded from [here|http://raibledesigns.com/wiki/attach?page=RichClient%2Flib.zip].

Now you should be able to compile and run your application (org.appfuse.richclient.PetClinicClientServer)

%%note __NOTE:__ Please ensure that your server is running ([http://localhost:8080/appfuse/ws/Clinic-hessian| http://localhost:8080/appfuse/ws/Clinic-hessian] displays exception "HessianServiceExporter only supports POST requests")%%

!!! Unsolved issues [#8]

** On successfull login is thrown Exception ClassNotFoundException: net.sf.acegisecurity.context.SecureContextImpl

** on __userManager.getUsers(null)__ exception :

org.hibernate.LazyInitializationException

!! ClassNotFoundException

Username is not yet crypted so I recomend to add new user to your database with __username__:test, __password__:test.

On unsuccessful login everything is OK and is shown "Bad Credentials" message.

On unsuccessfull login is thrown exception - In each appfusem 1.8 is in classpath included __lib\spring-1.2-rc2\acegi-security-0.8.2.jar__ which contains net.sf.acegisecurity.context.security.__SecureContextImpl__ class so I dont know where should be the problem :(
