1. Re: ClassNotFoundException: com.metamatrix.data.api.Connecto
shawkins Jun 2, 2009 11:59 AM (in response to juanignaciosl)The simplest fix would be to recreate the connector binding under the new Designer milestone.
This looks like the same problem experienced by http://www.jboss.org/index.html?module=bb&op=viewtopic&t=152908&start=10. -
2. Re: ClassNotFoundException: com.metamatrix.data.api.Connecto
juanignaciosl Jun 2, 2009 1:38 PM (in response to juanignaciosl)I've updated to 6.1 designer and it won't change. I've deleted the connectors, created again and rebind them at the vdb.
It seems there's also some problems at the environment. When I boot Eclipse (I've already used -clean), 'Problems' view displays several:An exception occurred during console notification org.eclipse.swt.SWTException: Device is disposed at org.eclipse.swt.SWT.error(SWT.java:3777)
Problems occurred when invoking code from plug-in: "org.eclipse.ui.console". org.eclipse.swt.SWTException: Device is disposed

If I try to display data of an existing table(model view, 'preview data' button) it will throw the following:Unexpected exception for request 0.0 [ComponentNotFoundException]Connector Binding "myconnectorbinding" failed to start, or did not start correctly.

4. Re: ClassNotFoundException: com.metamatrix.data.api.Connecto
juanignaciosl Jun 2, 2009 2:08 PM (in response to juanignaciosl)It seems that the boot messages aren't important, since the metamatrix one is information, not error. Nevertheless, I can't figure ComponentNotFoundException cause...

juanignaciosl Jun 3, 2009 3:50 AM (in response to juanignaciosl)I've unpacked a clean Eclipse with only Teiid Designer (6.1.0) and created a new model project. The problem is the same.

6. Re: ClassNotFoundException: com.metamatrix.data.api.Connecto
shawkins Jun 8, 2009 10:42 AM (in response to juanignaciosl)Does everything work in designer 6.1.0 with the recreated bindings, but then fails with embedded?
What deployment profile are you using for embedded? It looks like you may have an old version of the connector api jar in your classpath, which could cause the exception.
http://www.jboss.org/community/wiki/TeiidEmbeddedDeploymentProfiles
and
https://www.jboss.org/community/wiki/DeployingTeiidEmbeddedinJBossAS
have been updated to better reflect 6.1 deployments. -
7. Re: ClassNotFoundException: com.metamatrix.data.api.Connecto
juanignaciosl Jun 9, 2009 5:26 AM (in response to juanignaciosl)Something freakin' strange must have been happening at my classloading. I've just followed that guide one more time and I even had this error:
Caused by: java.lang.ClassNotFoundException: com.metamatrix.jdbc.EmbeddedDataSource
After double checking everything I created a new jboss server install and errors were gone.
After all it seems it was a wrong mixing of wrong JDK (it needs JDK 6), wrong server (4.2.3 "normal" won't work with JDK 6, needs a different donwload) and some other mistakes...
Thank you very much for your support, I'll keep trying Teiid :) -
8. Re: ClassNotFoundException: com.metamatrix.data.api.Connecto
shawkins Jun 9, 2009 9:03 AM (in response to juanignaciosl)No problem, thanks for trying us out. Even though this is the 6 release series there's a lot that has changed since we were closed source. In response to this thread I worked TEIID-646, which should make the error you were seeing clearer.
