SQL sproc error: [DataDirect][OpenEdge JDBC Driver][OpenEdge

Hello,

     For starters, I'm new here, so please let me know if I should be posting in a different forum...   

I am trying to get stored procedures in OpenEdge SQL working for the first time. The SQL CREATE PROCEDURE statemant works fine (now that I found I had to change the delimiter to something other than a semicolon, that is...). However, we get the aforementioned error when running the CALL PROCEDURE statement. It's a 'Hello World' type example, I can't make it ant simpler, but I still can't figure out why it won't work. Here's some quick details:

Our application: Encompix ERP, developed in Progress OpenEdge 10.1C04

Our tools: OpenEdge Architect

Java version (from Control Panel in Windows): 6.0.330

OS: Windows Server Standard 2008 32-bit Service Pack 2

Code (We put all of our custom objects in an NSI namespace, so as not to conflict with Encompix):

/* NOTE: Changed OpenEdge architect delimiter to pipe symbol ( | ) to prevent conflict with Java semicolon line terminator */

DROP PROCEDURE NSI."HiWorld" |

CREATE PROCEDURE NSI."HiWorld" ()
BEGIN
    SQLIStatement Insert_HelloWorld = new SQLIStatement ("INSERT INTO NSI.HelloWorld(fld1) VALUES (’Hello World!’)") ;
    Insert_HelloWorld.execute() ;
END |

DROP TABLE NSI.HelloWorld
CREATE TABLE NSI."HelloWorld" (fld1 VARCHAR(100))|

CALL NSI."HiWorld"()|   /* Here's where we get the error:  [DataDirect][OpenEdge JDBC Driver][OpenEdge] Error in Stored Procedure Execution. (7853)... */

SELECT * FROM NSI."HelloWorld"|      /* Table is created, but no data inserted... */

Environment ("D:\apps\oe10\" is the OpenEdge installation directory):

     PATH: D:\apps\oe10\bin;d:\apps\oe10\jre\bin\client;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files\MySQL\MySQL Server 5.1\bin;C:\Program Files\Dell\SysMgt\RAC5;C:\Program Files\Dell\SysMgt\oma\bin;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\

     CLASSPATH: %CLASSPATH%;%DLC%\java\openedge.jar;%DLC%\java\util.jar;%DLC%\java\base.jar;%CLASSPATH%

Registry:

[HKEY_LOCAL_MACHINE\SOFTWARE\PSC\PROGRESS\10.1C\JAVA]
"JDKHOME"="D:\\apps\\oe10\\jdk"
"JREHOME"="D:\\apps\\oe10\\jre"
"JVMEXE"="java"

So, as you can see, I've checked the Java environment variables & registry keys,  but still get an error any time I run the simplest of java snippets inside an OpenEdge stored procedure. Any ideas? Also, all the documentation talks about Java version 1.4.x or 1.5.x. Is it a problem to have a newer version of Java than that? 

Thank you,
