blobdestination class howto debug

SiatGesiFeb 22 2018 — edited Feb 26 2018

my environment server:oracle 11.1.2.2 form report

database 11.2...

so windows

hi I would know if the code below if there is something wrong...

when the user runs a report by form using blobdestination to load a blob in a db blob column

but we note that the report remains on the report server...and i must kill those reports...

this is my error in log file

/////////////////////////////////////////////blobdestination class

* Oracle9i Reports

* Pluggable Destination Template v1.0

* This template is provided to act as a building block

* for your Oracle9iAS Reports Services Pluggable Destination.

* How to use this template:

* 1. Implement one or more of the methods. Prototypes are given

* for each method and the comments describe when the method is called.

* 2. Compile the class.

* 3. Copy the class to the machine with Oracle9iAS Rel 2 installed. Place

* it in $ORACLE_HOME/reports/jlib/classes. If you want to put it in

* a different directory, remember to add this new directory

* to the system CLASSPATH. If you wish to jar-up the class, you need to

* explicitly state the full path and filename of the jar in

* the system CLASSPATH.

* 4. Shutdown the Oracle9iAS Reports Services.

* 5. Edit the Oracle9iAS Reports Services configuration

* file <servername>.conf file as per the documentation

* to register your new destination class with

* Oracle9iAS Reports Services.

* 6. Restart Oracle9iAS Reports Services.

* 7. Run a job, with DESTYPE=Des+your destination name.

* Calling Sequence of methods:

* init() -- called on server startup

* foreach job

* {

* start() -- called on start of distribution of job to this destination

* foreach file in job

* {

* sendFile() -- call to send each file to the destination

* }

* stop() -- called on end of job to this destination

* }

* shutdown() -- called on server shutdown

* Note: it is also possible to sub-class the entire distribution ability by

* implementing the send() method instead of these individual methods.

* Please see the documentation for more information
