Subject Connect Cocoon 1.8 to SQL-Server? How to switch of connection poo ling?
Date Wed, 01 Nov 2000 15:13:35 GMT
Hi Folks!

WHAT I WANT TO DO
  Use Cocoon to connect to an Microsoft SQL-Server
  database and display it's contents.

WHAT I TRIED ALREADY
  Downloaded and installed Cocoon 1.8 (on top of
  Win2K, Apache 1.3.12, Tomcat 3.1)

  First http://server/Cocoon.xml resulted in some
  turbine error, which was solved after downloading
  version 1.5 of turbine-pool.jar from CVS.

  Then I copied and modified /samples/sql/esql.xml 
  to use Sun's JDBC-ODBC-Bridge:

  ...
  <esql:driver>sun.jdbc.odbc.JdbcOdbcDriver</esql:driver>
  <esql:dburl>jdbc:odbc:MyDataSourceName</esql:dburl>
  ...

PROBLEM
  When accessing /samples/esql.xml I get:

  java.lang.Exception: XSP Java Compiler: Compilation failed for _esql2.java
  45: Incompatible type for method. Explicit cast needed to convert
    org.apache.turbine.services.db.PoolBrokerService to
    org.apache.turbine.util.db.pool.DBBroker.

		 static DBBroker _esql_pool = DBBroker.getInstance();
                                                ^
  Note:
C:\apps\apache\tomcat\bin\repository\_C_\_projects\_wwwroot\_samples\_sql\_e
sql2.java 
  uses or overrides a deprecated API.  Recompile with "-deprecation" for
details.

QUESTION
  When looking at cocoon.properties, I understand that SQLServer
  is current not supported by the new "connection pooling" feature.
 
  Does the error come from this fact?

  Is it possible to somehow switch of connection pooling for
  SQLServer?



MANY Thanks in advance
Goetz
