Re: [JBoss-user] Oracle Connection Pool Startup - Null Pointer Error

2001-05-15 Thread Guy Rouillier 

You get a null pointer exception when JBoss cannot establish a connection.
The most common cause is not supplying a valid userid/password combination.
Having the wrong Oracle instance name would probably also cause it.

NPEs in Minerva on startup are a known problem.  The cause is usually a
misconfiguration, but it should be reported more informatively.

[JBoss-user] Oracle Connection Pool Startup - Null Pointer Error

2001-05-13 Thread john cooney 

I am having lots of problems starting an Oracle connection pool, I
am getting a null pointer exception.

I am using: win 2000, Oracle 8.1.6 and JBoss 2.2.1.

The instance DOES appear to have started. I can connect to the database
using the JBuilder 4 JDBC explorer.

I am using the XADataSourceImpl class (not the Oracle one).

jboss.jcml looks like this:

  
  
 oracle.jdbc.driver.OracleDriver
  

  
OracleDS
org.opentools.minerva.jdbc.xa.wrapper.XADataSourceImpl
jdbc:oracle:[EMAIL PROTECTED]:1521:DB
scott
tiger
  

This is the stack trace:
