That did help, Vincent - thank you! After putting the right JAR files into the WEB-INF\lib directory, I have managed to make a connection to a remote DB2 database and even format the results into a proper wiki table (even with links): {{groovy}}
import groovy.sql.Sql sql = Sql.newInstance( 'jdbc:db2://<database>/<database>', '<user>', '<password>', 'com.ibm.db2.jcc.DB2Driver' )
println "|=Name|=Type|=Length|=Nullable";
sql.eachRow("SELECT colname, typename, length, nulls FROM SYSCAT.COLUMNS WHERE tabname = '<table name>' and tabschema = '<schema>' ") { row -> println "|[[$row.colname]]|$row.typename|$row.length|$row.nulls"; }
{{/groovy}}
Now my question is - how can I convert that plaintext URL into using a datasource? I saw the link on your "Execute SQL" page which referred to a page on StackExchange, but I can't seem to figure it out. It can't be as simple as using "ConfigurationHolder" and putting the values in xwiki.cfg or something, is it? Thanks! On Sun, Sep 9, 2012 at 3:13 AM, Vincent Massol <[email protected]> wrote:
Hi Matt,

Hi all, I am trying to get a wiki page to display the tables in my DB2 database (on an AIX system, not an OS/400). I'm confused about how to configure Groovy to make the connection, though. I went here:
http://extensions.xwiki.org/xwiki/bin/view/Extension/Execute+SQL
So far, I have come up with this syntax:
{{groovy}} import groovy.sql.Sql sql = Sql.newInstance( 'jdbc:db2://AAA:BBB/CCC', 'DDD', 'EEE', 'com.ibm.db2.jcc.DB2Driver' ) sql.eachRow( 'list tables' ) {{/groovy}}
AAA = server name BBB = port CCC = database name DDD = user EEE = password
This syntax doesn't work - it results in "ClassNotFoundException" errors.
First question: do I have the syntax right?
No idea, I've never used this. I have just copied the information from http://groovy.codehaus.org/Tutorial+6+-+Groovy+SQL and put it on http://extensions.xwiki.org/xwiki/bin/view/Extension/Execute+SQL
Second question: I assume I have to provide Groovy some DB2 zip/jar file, but where should that file be placed in my Tomcat/MySQL installation?
You need to put the db2 jar In your webapp's WEB-INF/lib directory. This is probably why you get the CNFE.
Third question: I know I will have to manipulate the query result so that the output will have wiki elements (like clickable links). Does anyone have any examples of how they displayed their results, preferably with tables and links?
You just need to use wiki syntax…
To do that from Groovy you'd use: print and println. For ex: println "Some **bold**"
See the syntax guide to learn how to use tables/links.
Hope it helps, -Vincent
