Subject Re: Can not cast oracle.sql.ARRAY to oracle.sql.ARRAY
Date Wed, 25 Aug 2010 11:45:20 GMT

1)Do not put the same jar in /usr/local/tomcat/lib/ and in /WEB-INF/lib/  try 
the one of them.Jars placed in /usr/local/tomcat/lib/ should be the first loaded 

2) Why is it not enough to use only ojdbc14.jar?  why you include classes12.jar?

Subject: Can not cast oracle.sql.ARRAY to oracle.sql.ARRAY

Can not cast oracle.sql.ARRAY to oracle.sql.ARRAY 
I have an app that was working find under Java 1.4, Tomcat5 and Axis2 1.4. Under 
Java 1.6, Tomcat6 and Axis2 1.4 it seems to be mostly working, but there is one 
exception that I can not seem to get rid of.

Caused by: java.lang.ClassCastException: oracle.sql.ARRAY cannot be cast to 

I put some debug around the offending line of code, thus:

      Object o = p_Stmt.getObject(1);
      System.err.println( "Got class " + o.getClass() );
      oracle.sql.ARRAY arry = (oracle.sql.ARRAY)o;

and that prints

Got class class oracle.sql.ARRAY

so it's definitely an oracle.sql.ARRAY

The best information I can find about this sort of error suggests that there is 
an issue somewhere with different class loaders loading up the class, probably 
one at the Tomcat level and one at the Axis2 level. This didn't see, to cause 
any problems on the older configuration, provided that the same version of 
classes12.jar was used by both Tomcat and Axis2. Unfortunately on the newer 
configuration I have been unable to get it to work.

As far as I can see the jar is in 2 places, i.e. 
/usr/local/tomcat/lib/classes12.jar and axis/WEB-INF/lib/classes12.jar.

I have updated it to the more recent ojdbc14.jar, which did not help. I have 
also examined every jar under /usr/local/tomcat/ and axis/WEB-INF/ to look for 
conflicting definitions.

I am now stuck. Can anyone help me resolve this issue, please?
