SQLJ Translation does not create profile file

Question

SQLJ Translation does not create profile file.
After translating a small file HelloWorld.sqlj
the following files are created:
HelloWorld_SJProfileKeys.class
HelloWorld.class
HelloWorld.java
Although there is a HelloWorld_SJProfileKeys.class, profile file HelloWorld_SJProfile0.ser has NOT been created.
The starting file .sqlj file HelloWorld.sqlj is taken from O'Reilly book 'Java Programming with Oracle SQLJ' by Jason Price. The file contains a valid SQL statement to display the date.
My environment variables were set up with instructions from:
http://www.onjava.com/pub/a/onjava/2001/12/05/learning_sqlj.html
When I run java HelloWorld to run the .java file, I get the error:
SQLException java.sql.SQLException: profile HelloWorld_SJProfile0 not found: java.lang.ClassNotFoundException: HelloWorld_SJProfile0
I searched the internet high and low for a similar error to mine but I could not find a match.
I read the following text from http://otn.oracle.com/tech/java/sqlj_jdbc/htdocs/faq.html#translationerrors
but it does not help me.
"ClassNotFoundException: xxx.yyy_SJProfile0 for class xxx.yyy_SJProfileKeys
If you see an exception such as:
java.sql.SQLException: profile xxx.yyy_SJProfile0 not found:
java.lang.ClassNotFoundException:
xxx.yyy_SJProfile0 for class xxx.yy_SJProfileKeys
then you must ensure that the SQLJ profile(s), such as xxx/yyy_SJProfile0.ser, is available in the SQLJ runtime environment. This includes JARing this file as part of an applet deployment, or publishing it to the server via loadjava.
Any ideas? Thanks in advance,
John

SQLJ Translation does not create profile file.
After translating a small file HelloWorld.sqlj
the following files are created:
HelloWorld_SJProfileKeys.class
HelloWorld.class
HelloWorld.java
Although there is a HelloWorld_SJProfileKeys.class, profile file HelloWorld_SJProfile0.ser has NOT been created.
The starting file .sqlj file HelloWorld.sqlj is taken from O'Reilly book 'Java Programming with Oracle SQLJ' by Jason Price. The file contains a valid SQL statement to display the date.
My environment variables were set up with instructions from:
http://www.onjava.com/pub/a/onjava/2001/12/05/learning_sqlj.html
When I run java HelloWorld to run the .java file, I get the error:
SQLException java.sql.SQLException: profile HelloWorld_SJProfile0 not found: java.lang.ClassNotFoundException: HelloWorld_SJProfile0
I searched the internet high and low for a similar error to mine but I could not find a match.
I read the following text from http://otn.oracle.com/tech/java/sqlj_jdbc/htdocs/faq.html#translationerrors
but it does not help me.
"ClassNotFoundException: xxx.yyy_SJProfile0 for class xxx.yyy_SJProfileKeys
If you see an exception such as:
java.sql.SQLException: profile xxx.yyy_SJProfile0 not found:
java.lang.ClassNotFoundException:
xxx.yyy_SJProfile0 for class xxx.yy_SJProfileKeys
then you must ensure that the SQLJ profile(s), such as xxx/yyy_SJProfile0.ser, is available in the SQLJ runtime environment. This includes JARing this file as part of an applet deployment, or publishing it to the server via loadjava.
Any ideas? Thanks in advance,
