Running Reports with Oracle Report Server 10G using a web browser

Of course, it's possible to run Oracle reports with a simple http request.
This approach only requires Oracle Report Server installed on the machine/server and responding on its port 8889.

• Verify that you have all license rights to install Oracle Report Server


• Install a PDF reader (personally I love foxit reader)


• Verify that these environment variables are set:
  REPORTS_PATH = C:\your_reports_folder;
  PATH=C:/DevSuite10_home;C:/OLD_DevSuite9_home;etc...
  Important: Make sure your latest Dev
  Suite is on your PATH environment variable first, before any older versions!


• Start OC4J


• Start your web browser and run your report using this sintax:
  http://<reports server name>/reports/rwservlet?report=<report file name>&<other report parameters>

Example:
http://localhost:8889/reports/rwservlet?report=rep_007.rep&userid=username/password@192.168.19.58:1
521/ORCL&desformat=pdf&destype=cache&YOUR_REPORT_PARAMETER1=image.bmp&OTHER_REPORT_PARAMETERS=...

Common problems:
If your report calls other libraries, these must be in the same directory of the report, and must be compiled/recompiled with Oracle reports builder 10g.

To avoid errors like the following:

Not able to load oracle.reports.util.EnvironmentGlobal class
Using oracle.reports.util.Environment class

you must also generate/regenerate REP file using 10g Report Builder AND check whether the file/folder has enough privilege to the logged in user.
If you still have problems try to copy it to another folder: there might be problem with the acess right in your folder.
