DataSourceLoader

[Manu549651]

Hi, great Gurus !

I'm trying to make work in my project the example of SmartGWT's documentation (Part 5. Databinding -> DataSource).

I'm using:
- SmartGWT 2.4
- Firefox 4.01

I think the main problem comes from the the path of DatsSourceLoader.

Which servlet-mapping should I put in web.xml ?
Here is mine:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app
    PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
    "http://java.sun.com/dtd/web-app_2_3.dtd">

<web-app>
  
	<session-config>
		<session-timeout>1</session-timeout>
	</session-config>
  
  <!-- Servlets -->
  <servlet>
    <servlet-name>tipiServlet</servlet-name>
    <servlet-class>com.tipi_v1.server.TipiServiceImpl</servlet-class>
  </servlet>
  
  <servlet-mapping>
    <servlet-name>tipiServlet</servlet-name>
    <url-pattern>/tipi_v1/tipi</url-pattern>
  </servlet-mapping>
  
  <!-- Default page to serve -->
  <welcome-file-list>
    <welcome-file>Tipi_v1.html</welcome-file>
  </welcome-file-list>

</web-app>

or should I add a servlet ? Like this ?

 <servlet>
     <servlet-name>DataSourceLoader</servlet-name>
     <servlet-class>com.isomorphic.servlet.DataSourceLoader</servlet-class>
   </servlet>

Which is the path of the DatasSourceLoader I should put in the header of Tipi_v1.html :
I'm trying this but it doesn't work:

<script src="/src/DataSourceLoader?dataSource=contacts"></script>

When I try this:

DataSource contactsDS = DataSource.get("contacts");
		ListGrid grid = new ListGrid(); 
		grid.setDataSource(contactsDS);

this is the result in "development mode":

And this "tipi_v1/war/ds/contact.ds.xml" (the exact copy of the example of the doc):

<DataSource ID="contacts">
<fields>
<field primaryKey="true"
name="id" hidden="true" type="sequence" />
<field name="salutation" title="Title" type="text" >
<valueMap>
<value>Ms</value>
<value>Mr</value>
<value>Mrs</value>
</valueMap>
</field>
<field name="firstname" title="First Name" type="text" />
<field name="lastname" title="Last Name" type="text" />
<field name="birthday" title="Birthday" type="date" />
<field name="employment" title="Status" type="text" >
<valueMap>
<value>Employed</value>
<value>Unemployed</value>
</valueMap>
</field>
<field name="bio" title="Bio" type="text"
length="2000" />
<field name="followup" title="Follow up" type="boolean" />
</fields>
</DataSource>

I tried to put the same file in : "tipi_v1/src/com/tipi_v1/shared/ds/contact.ds.xml". It doesn't change anything.

If anyone has got an idea, thanx 1000 times !

Here are the correct installation instructions, including troubleshooting steps. However, from the errors you're getting, you skipped a number of these steps, so start over from the top.

[Manu549651]

I'm trying to install it but I've got a few questions:

1. I'm using SmartGWT 2.4 and not SmartGWT Pro/EE.
Should I still follow the page you advised me ? Or is there another more appropriate page ?

2. Whre can I find (or create myself) these 2 files: server.properties, log4j.config.xml ?

3. Am I obliged to put in the build path every file I see on this linked page ?

"For server-side .jars, dependencies are documented here."
http://www.smartclient.com/smartgwte...endencies.html

And on that page, some libs are unfindable. Can't they put links ?

Thanx a lot !

[Isomorphic]

If you're doing something with the DataSourceLoader, then yes, you're using Pro/EE.

Everything the instructions refer to are in the package you downloaded, and the instructions tell you exactly where. Slow down, and read carefully.

[Manu549651]

As I can see in SmartGWT Overview, it is possible to use databinding with SmartGWT LGPL. But can I use Hibernate (to get datas from MySQL server) with this kind of databinding ?
And how can I do this without using a DataSourceLoader ?
Thanx !

[Isomorphic]

Hmm. The QuickStart Guide also explains how to integrate with the server if you aren't using our server software, but that's more challenging. You probably want to continue with Pro+.

Again these install instructions are used every day, are complete, and work. Just be sure to follow them very carefully.

[Manu549651]

What is Pro+ ? I want to do it with SmartGWT LGPL, not with any other.
And for which reasons is it gonna be "more challenging" ?
Thanx !
