Yes your are right! I don't know why it was part of the requirement to
add a JDBC line to explicitly set the behaviour of autocommint to
*true*, when it was the default value. Perhaps it has to do with "just
making sure it is" sort of thing.
Thanks Dave, I'll let the my group know.

Either way this is expected behaviour as psql also has autocommit true
by default.
Thanks,

Thanks Dave for your interest.
In the OP I started by explaining the difficulties when trying to
create a tabelspace using JDBC; please note that when using the
PG-15 prompt I did not have the problem. Well, it turns out that
while developing the request for help (writing the email), I
realize that my code had the following line :
*this.conn.setAutoCommit(false);*/*
*/However, in my research, I had read a post mentioning that by
setting /auto commit/ to *true* the issue was solved. So, I
changed that line of code in my algorithm to :
*this.conn.setAutoCommit(true);*/*
*/Which also resulted in my app working without any errors./**/
Please read the code-snip I submitted; there you can see that line
of code I edited; which I commented with "/*//*//*game changer!!".*/
Thanks again Dave, have great week.

Hi Amn,
Can you help me understand this issue better?
I don't see anywhere in the code where you are attempting to
create a tablespace ?

Hello.
I have searched the net in an attempt to find if others have
had and resolved this challenge, but most of the sites talk
about how, when using the psql, this error arises. In my
case, the error arises only when access PG-15 using JDBC.
JDBC connects to the database, but when trying to execute a
schema, it be to create a database or to create a tabelspace
I get this error :
*StackTrace : [Ljava.lang.StackTraceElement;@7a69b07**
**Message : ERROR: CREATE TABLESPACE cannot run inside a
transaction block*
I have used the same algorithm, but now modify to accommodate
PG-15, when using SQLite. So the JDBC code might not be the
problem, but the requirements needed from PG-15.
Change of perspective, I resolved the concern!
Here is what changed the outcome :
--- snip ---
public void connectToDatabase() throws
ClassNotFoundException, SQLException {
try {
Class.forName(this.getDatabaseClass().toString());
this.conn =
DriverManager.getConnection(this.getDatabaseUrl().toString(),
this.getUserID().toString(),
this.getUserPassword().toString());
*this.conn.setAutoCommit(true);*/*//*//*game changer!!*/
this.pout("Connected to the PostgreSQL server,
success!!!");
this.stmt = this.conn.createStatement();
} catch (final SQLException | ClassNotFoundException e) {
throw e;
}
}
--
All I had to do was to setAutoCommit to true, PG-15 set this
value to false by default.
I hope my experience can help others.
