The datasource has not been loaded. Did you load the DataSource definition?

Load the DataSource definition client-side by including the following line in the body of your GWT host html file.

<script src='sc/DataSourceLoader?dataSource=employees,supplyItem'></script>

Specify a comma separated list of DataSource ID's for the dataSource parameter. The above line would load the employees and supplyItem datasources from the server.

See the Getting Started doc.

starter question

Ok, great example.

I'm trying to get my grips on smartgwt ee. I thought an easy step by step approach would be the best, so I want to change the SQL CRUD example in the showcase to connect to my own PostgreSQL database. However, it doesn't seem to obtain the correct datasource (I'm sure it must be a stupid little detail).
What I did was:
1. I created a datasource with the datasource wizard.
2. I placed it in the /ds directory
3. I changed server.properties, uncommented the postgresql definitions, changed them to the correct database settings; just to be sure I also put this databse as the default.
4. In SQLCrudSample.java, I changed the datasource definition to: DataSource dataSource = DataSource.get("agenda");

When I access the example in the browser, I get the following error:

Uncaught JavaScript exception [java.lang.NullPointerException: null
	at com.smartgwt.client.widgets.grid.ListGrid.setDataSource(ListGrid.java:7943)
	at com.smartgwt.sample.showcase.client.dataintegration.java.crud.SqlCrudSample.getViewPanel(SqlCrudSample.java:89)
	at com.smartgwt.sample.showcase.client.ShowcasePanel.<init>(ShowcasePanel.java:82)

So somehow the datasource isn't recognized. Any clues?

Edit profile dependent data

Hello,

I was wondering how profile dependent data editing is best done with smartgwtee. For example, I have an application when clients can log in, and they would have the possibility to edit their own contact data. How would I make sure they only edit their own data? Is there some way to bind session dependent data to the database query? Or would this require a javabean datasource?

Best regards, Bo

A new SmartGWT Pro / Enterprise package has been released with radically expanded documentation, including documentation of all elements and attributes that are legal in .ds.xml files, and overviews of how to use them. See the first post in the thread for pointers into the some of the most interesting new documentation, as well as the download link for the new version.

If the new documentation still leaves you with questions, this is a good place to post them.

You can alternatively inherit

<inherits name="com.smartgwtee.tools.Tools"/>

and programatically call

com.smartgwtee.tools.client.SCEE.openVisualBuilder();

We'll look into adding a simple convenience project with an ant target that launches the Visual Builder.

Visual Builder is included in the Showcase. The Showcase is included in the SmartGwt EE package as a deployable .war.

Visual builder

@ceravolo the problem is that it's simpler than you think :) For a basic connection to Hibernate no Java is generated or needs to be written.

Go into the Visual Builder and pick "New", then "Existing SQL Table (via Hibernate)". You will see a list of beans you have registered with Hibernate. Pick one, pick Next, pick "Save DataSource". Your new DataSource is the first in the list and can be immediately dragged onto components within Visual Builder and used for search, update, add, remove.

To load it in your application use the technique shown in the samples of creating a .jsp with a loadDS tag as the only contents, and using <SCRIPT src=> to load that .jsp. Having done so, you get the live DataSource instance via DataSource.get("dataSourceId").

You don't need to write any Java until you want to add business logic - see the DMI settings on SupplyItemSpringDMI.ds.xml in this sample for an example of that.

Note we're also eliminating the need to create a .jsp with a loadDS tag in the next revision.

Where can i find the visual builder? I'm using myeclipse

Okay, that's the Enterprise theme.

smartgwt-skins.jar is required only if you're using themes other than Enterprise. We'll add this file in our next release. Out of curiosity, which theme are you currently using?

I have this in my module file - not sure it's correct but I like what I see.

<inherits name='com.smartclient.theme.enterprise.EnterpriseResources' />

Thanks for the quick reply,
Eric

Hi Eric,
You'll need to update your isomorphic_*.jar files pretty much with every new release of SmartGWT EE unless no SmartGWT Server code change was made between releases which is quite unlikely. We'll add a version to the jar files in a future release.

You don't need isomorphic_js_parser.jar. We'll update the Eclipse project files in the next release.

A new release of SmartGWT EE is available for download.

Hi Isomorphic,

I was wondering if you would consider added version numbers to the isomorphic_*.jar files to make it easier to upgrade from version to version? With version numbers you can just glance and see if you need to replace the jar.

Also, I'm not seeing the smartgwt-skins.jar or the isomorphic_js_parser.jar. Are they not needed or replaced/included?

Thanks,
Eric

Spikelee can you send me a ping mail on csergiu77@yah__.com
I would like to exchage some info related to smartgwt ee.
Thx

[spike00lee]

This is just a FYI..

I have imported several of the examples into eclipse and it is much easier than before (version 1.1) when I had to do it manually, So thanks very much for the eclipse project files. Just a note that it is trying to add 4 jar files that do not come with the distribution and don't seem to be needed. I just remove them from the build path and then it can build. Every sample that I have imported has the same problem. Here are the jar files in question...

isomorphic_embedded_tomcat.jar
isomorphic_examples.jar
isomorphic_js_parser.jar
isomorphic_realtime_messaging.jar

A new release of SmartGWT EE is available for download.

New in this release:

- Many new examples, covering custom DataSource implementations, Batch Upload, and various scenarios of adding business logic
- Eclipse project files for each sample project, for one-step Eclipse setup

[csergiu77]

So ? How it is after all ?
