Error using DataSource with schemaBean in Pro-Version

[jstegemann]

Hi,

using SmartGWT Pro 2.4 I am getting the following error multiple times when starting my sever:

The Batch DataSource Generator feature is only available with the Enterprise license

I am not calling the "Batch DataSource Generator" explicitly, as far as I know. I am also not using any tools at all. All I want to do is using the schemaBean attribute withing my datasource-definitions. Do I need an Enterprise license to do so? I did not get this from the documentation...


Thank your very much for your help,

Jens

No, you don't. The most likely explanation is that you are still using .jars from an older version. If not, try to isolate what server-side calls or configuration files you have that are causing these warnings.

Hi,

when trying to run my own sample application (based on the samples for JPA, DMI and custom datasources) the same error occurred.

I am also using SmartGWT Pro 2.4

The exception was thrown, when the application was started in development mode and when the DSRequest.execute() method is called.

This is my datasource definition:

<DataSource 
    ID="custom" 
    serverConstructor="com.isomorphic.jpa.JPADataSource"
    schemaBean="com.smartgwt.sample.server.Contact">
    <field name="id" type="sequence" hidden="true" primaryKey="true" />
    <field name="name" type="text" title="Name" required="true"   />
    <serverObject className="com.smartgwt.sample.server.DMIHandler" methodName="doIt"/>
</DataSource>

This is my DMIHandler class:

public class DMIHandler {
    
    public DMIHandler() {
        System.out.println("Starting DMIHandler");
    }
    
    public DSResponse doIt(DSRequest dsRequest) throws Exception {
        System.out.println("DOING IT!!!");
        return dsRequest.execute();
    }
}

The stack trace is not showing any particular code I have written, just:

I'm having the same problem. Were you ever able to fix it?

[Isomorphic]

The previous poster (jkugelberg) has a flawed DataSource definition (no <fields> around the <field> element) and a very strange stack trace - almost as if the DMI logic introduced a second DataSource *after* the schemaBean attribute and JPA DataSource had already completed successfully.

dirkg:

1. is your stack trace the same?
2. if so, can you see anything in your logic that might introduce a second DataSource - what if you remove all DMI logic?
3. does downloading the latest nightly from smartclient.com/builds fix the problem for you?

[dirkg]

This is my stack trace (it's pretty much the same as jkugelberg's):

This is my DataSourceDefitinion (with some names replaced to make the legal department happy). I'm not using DMI, I'm using a custom DataSource. GizmoDataSource derives from BasicDataSource.

<DataSource
    ID="gizmos"
    serverConstructor="com.foo.server.GizmoDataSource"
    schemaBean="com.foo.client.Gizmo">
    <fields>
        <field name="categoryId" type="integer" required="true" hidden="true"/>
        <field name="key" type="text" required="true" hidden="true" primaryKey="true"/>
    </fields>
</DataSource>

This is my Gizmo class:

public class Gizmo implements Serializable {
	private static final long serialVersionUID = -7654454066860882427L;

	// Can't make these final because then they won't serialize.
	private String m_displayString;
	private long m_categoryId;
	private Double m_score;
	private MyEnum m_myEnum;
	private boolean m_available;

	public Phrase() {
	}

	public Phrase(
			final String displayString,
			final long categoryId,
			final Double score,
			final MyEnum myEnum,
			final boolean available
	) {
		m_displayString = displayString;
		m_categoryId = categoryId;
		m_score = score;
		m_myEnum = myEnum;
		m_available = available
	}

	public String getDisplayString() {
		return m_displayString;
	}

	public long getCategoryId() {
		return m_categoryId;
	}

	public Double getScore() {
		return m_score;
	}

	public MyEnum getEnum() {
		return m_myEnum;
	}

	public boolean getAvailable() {
		return m_available;
	}

	public String getKey() {
		/* key is assembled from other parts of the class */
	}
}

I will try the nightly right now.

[dirkg]

I tried the nightly, I get the same problem.

[Isomorphic]

There was indeed a problem here. We've fixed it, the fix will be present in nightly builds as of tomorrow.

[dirkg]

Thank you so much! I'll try it out as soon as possible.

[jkugelberg]

Thanks for the feedback.
Now there is just one question left: Will there be a regular update containing the fix (not only a nightly build)? If yes, when will it be available?

[dirkg]

I just verified the fix. Fantastic! Thank you! Like jkugelberg, I can't wait for the final version 2.5 to come out.
