Sharepoint Integrated Reporting Services Web Parts not showing up.

have you already configured SSRS for integration mode?  and then installed the report web viewer add in?

in my experience, ssrs & sharepoint integration can be tricky.  if you don't follow the configuration steps IN ORDER, stuff doesn't work right.

i read that article when i was installing everything, and it all looks good.  The problem that i'm having is when i connect the report viewer to the report explorer the site errors and i have to go and close the wep part manually.

so if i'm understanding correctly...
ssrs shows a green light for sharepoint integration
you were then able to go into central admin and configure Report Integration settings...
you can see the sql report web part in the list of available web parts...
but they are giving you a problem when you actually use them.

yes?

if this is the case, please post exact errors that you see.  if no errors show in the user interface, please check Event Viewer on your web front end server.

error is the awesome sharepoint error:

An unexpected error has occurred.

Web Parts Maintenance Page: If you have permission, you can use this page to temporarily close Web Parts or remove personal settings. For more information, contact your site administrator.
Troubleshoot issues with Windows SharePoint Services.

if you try to open the page again, throws this error.  when you click on the link you can close the viewer web part, and the page works again.

i'm assuming that you've configured the viewer to display a report.  are you able to view this report outside of sharepoint?  does this happen with all reports, or just one?

can you also see if Event Viewer on the web front end server has a more specific error?

what i did was open up the report explorer web part, browse to the report, open it up, then go to connections> show report in > report viewer.

i didn't do any specific configuration for the viewer web part.

yeah i can view it outside of share point

this seems to be the error in event viewer

it seems my problems actually stem from different web apps being created with different accounts.  the SQL report services add-ins were installed on Central Admin web app but not on any other ones.  Thanks for your help and attention
