I have the following scenario:
I check inventory ( where I also lock a row using the SELECT FOR UPDATE statement by looking up the data source, etc ), and then I run a pipeline processing where one of the steps also do the same thing above, please don't ask me why I have to do this, it's some business requirement. anyway, the second SELECT appears to block ( nothing happens in the log file after reaching the statement ). Does this mean that each call to DataSource.getConnection return a new Connection rather the connection that is implicit in the current transaction ( for example through ThreadLocal ) ? Isn't this like transactionally wrong ?
During the pipeline processing I am also accessing other CMPs, etc.
I am using JBoss 3.2.3 Java 1.4.2, on Windows 2000.
Please help somebody with JBoss Internals knowledge.
