Upgrade from SmartGWT 12.1p to 13.0p: DMI not found

[rle125]

We use JPA annotated entity classes and JPADataSource in our ds.xml.

The application server starts clean and the browser is able to successfully load the datasources (DataSourceLoader?dataSource=myDMI).

I tried replacing all the JARs with the SmartGWT 13.0p distribution versions.

I made sure Init.go() is called first.

But we're still seeing the null Exception

I did notice that SmartGWT 13.0p uses hibernate3.jar but our application requires hibernate 4.2.17 (core, entity-manager, commons-annotations).

Are there any further troubleshooting steps you can suggest?

[Isomorphic]

As a basic part of installation, yes, please upgrade all related jars as part of the installation process, as well as following all other installation steps. Frequently, problems will occur just because a partial installation was done, and the deployment ends up with mutually inconsistent files.

Having done the full installation, if the problem still occurs, as far as these errors, just to cover the basics..

1) are you actually using EJB?

2) are you actually using JPA?

3) have you declared a JPA-managed bean and are you using dataSource.autoDeriveSchema to interact with it?

4) do you have any logic that is automatically executed at application startup?

On the last point, there are seeming concurrency problems. It's not clear if these are problems resulting from a more basic error (like mismatched file versions), however, if you have logic that is kicked off at servlet start, or anything like that, we would need to know about it. Any such logic needs to run after Init.go() in the SmartClient framework, or needs to call Init.go() itself.

Edit: In our eagerness to provide a timely response, our team posted a duplicate message on this thread. We apologize for any confusion this may have caused and have since removed the redundant response to keep the conversation clear and focused.

I verified all of the things from the DataSource FAQ.

I was able to get more logging, but it mainly shows validation, all of which seemed OK.

Were there 3rd party JARs that need updating when upgrading from 12.1p to 13.0p? I only upgraded the smartgwt and isomorphic specific JARs.

Here is the full stacktrace:

[Isomorphic]

The SmartClient server uses log4j for logging. This can be configured as described in the documentation here: https://smartclient.com/smartclient-....serverLogging

The default levels would typically show you some useful information - likely an error message and stack trace - when a dataSource is failing to load. It may be worth verifying whether you have modified the default settings, and consider decreasing the logging threshold for at least com.isomorphic.servlet.DataSourceLoader to get additional information.

If you're not able to load any dataSources this suggests a configuration issue perhaps.
We'd recommend you review the deployment process you took when upgrading to 13.0, and also review the full server logs to see if there are any other warnings that may indicate what's going on.

project.datasources is defined in our server.properties:

project.datasources: $webRoot/ds, $webRoot/myApp/ds

DataSources are loaded thorugh JSP:

<script src="myApp/sc/DataSourceLoader?dataSource=myDMI"></script>

I don't believe any DataSources are being loaded.

Is there logging we can enable to get more information regarding the DataSource loading?

[Isomorphic]

It does seem strange that you're getting this failure with no additional error logging.

Firstly - can we confirm your setup:

The error log looks like you are attempting to load a dataSource you created called "myDMI" (myDMI.ds.xml).

The server.properties configuration file governs where the SmartClient system will look for DataSources, via the property "project.datasources"
See this guide: https://smartclient.com/smartclient-...rceDeclaration

Can you confirm that project.datasources is configured to point to the correct location to pick up your ds.xml file?

How are you attempting to load the DataSource -are you hitting the DataSource loader URL directly or using a loadDS jsp tag or something else?

Are you having problems loading other dataSources? If you import something like the SupplyItem dataSource, does it get served correctly?

If you are able to load other dataSources, but not this one, we'd recommend you share that DataSource file with us directly. You can use the support@isomorphic.com email address for this to avoid leaking any sensitive content if necessary.

SmartGWT 13.0p / TomEE 8.0.14 / Firefox 115

After upgrading from SmartGWT 12.1p to 13.0p, we get the following exception:

ERROR [com.isomorphic.servlet.DataSourceLoader] (https-jsse-nio-8443-exec-1) BaseServlet Global Exception

javax.servlet.ServletException: DataSource 'myDMI' failed to load due to an exception on the server:

null

See the server-side log for additional details.

I verified myDMI exists in the same location as when it was working w/12.1p.

I don't see any additional server-side log details either.

Is there a way to get more detail regarding this error?
