15. Re: Twitter VDB

divadatabase Mar 27, 2013 1:47 PM (in response to van.halbert)

Hi Van,

I tried to query it from Eclipse using JDBC but I got the following error:

TEIID30352 Remote org.teiid.api.exception.query.QueryPlannerException: TEIID30352 TWITTER.INVOKEHTTP does not exist.

When you say use the simple client quickstart, can you be a little more specific? Do I:

1. Go to the simpleclient directory in windows explorer
2. Open and command window
3. Input the query: mvn install -Dvdb=twitter -Dsql="select * from tweet where query= 'jboss'"

Is that right?

I also downloaded Maven, do I use that directory for anything? (I'm not very familiar with Maven but I've been researhing it)

Thanks,
Danah

Here's a link that discusses installing maven on different OS's: http://www.sonatype.com/books/mvnref-book/reference/installation.html
Its not hard, just a few differences depending on the OS.

As for running from Eclipse, it should have worked. Can you paste the exception from the server log?

Thanks.

Check your twitter-vdb.xml, to make sure the model name is "twitter"

Ex:
    <model name="twitter">
        <source name="twitter" translator-name="rest" connection-jndi-name="java:/twitterDS"/>
    </model>

It appears the virtual model (twitterview) is referencing :

call twitter.invokeHTTP

and the name of the model has been changed.

Silly me.

Your're right, that fixed it. I can now query it from Eclipse.

One more thing Van, how do I see the virtual table?

All I'm getting is output like this:

Wed, 27 Mar 2013 18:44:11 +0000
Jboss_Nwankwo
Wed, 27 Mar 2013 18:43:04 +0000
Jboss_Nwankwo
Wed, 27 Mar 2013 18:40:56 +0000
Delmistique
...

Now can I use the command window to query it? How? Will I see a table?

Thanks a lot!

Danah,

I would recommend getting a SQL tool, like SQuirrel (http://squirrel-sql.sourceforge.net/). This will enable you to see all the tables and metadata that is exposed for the vdb that you are connected to. You can also submit queries and see the results. Very useful tool.

Hi Van,

Sounds good, I think I will start using that instead.

And I know you said I was correct about the list I wrote on executing a query using Maven, but I still got an error.

This is all new to me so please bare with me, I aplogize if I am irritating you.

Danah,

This is all good, it lets us know where there's usability issues so that we can improve it.

As for getting an error, I assume you ran the following steps:

1. Go to the simpleclient directory in windows explorer
2. Open and command window
3. Input the query: mvn install -Dvdb=twitter -Dsql="select * from tweet where query= 'jboss'"

Can you paste the error your seeing now?

van.halbert Mar 27, 2013 4:08 PM (in response to divadatabase)

Danah,

First, it appears your trying to run it from the maven directory. You need to "cd" into the simpleclient quickstart directory before running. Also, I believe as part of the maven install is to add C:\Teiid 8.3\Maven\apache-maven-3.0.5\bin to your PATH. Or you could run: C:\Teiid 8.3\Maven\apache-maven-3.0.5\bin\mvn install -Dvdb=twitter -Dsql="select * from tweet where query='jboss'"

I think its better to add maven to your PATH so that you don't have to fully qualify the path everytime you want to run maven.

Hi Van,

I've already set my Environmental Variable M2_HOME to C:\Teiid 8.3\Maven\apache-maven-3.0.5\bin.

cd into the simpleclient quickstart (cd simpleclient/ ) - from where?

Do I have to put my Maven directory inside of my simpleclient directory, or vice versa?

Thanks,

Danah,

open a terminal window and change the directory to the simpleclient directory (ex: cd {path}/simpleclient ). Once in that directory, now run:
mvn install -Dvdb=twitter -Dsql="select * from tweet where query='jboss'"

If maven is in your PATH, it should execute "mvn" and pass in the arguments: install -Dvdb=twitter -Dsql="select * from tweet where query='jboss'"
