Studio BIRT Print Step Fails with Invalid Application PrintService in Local-Out Transport
The error Integration Failed. com.capeclear.mediation.MediationException: application=BIRTEngine470 - Invalid application 'PrintService' in local-out transport with id='Call_PS_PutMessage' and endpoint='vm://PrintService/PutMessage'. The application may not be loaded.. See the consolidated report for further details
What it means
A Studio PDF-print (BIRT) step hands its output to a PrintService application bean over a local vm:// transport inside the same assembly. This error means the assembly can't find or load that PrintService application at runtime, so the print step never gets to render the design.
Troubleshooting
- Open the assembly and confirm a PrintService application actually exists and is deployed alongside the integration that references it, a local-out transport only works if both ends live in the same running assembly.
- Check the local-out transport's endpoint URL against the PrintService application's actual ID, a typo or a renamed application after a copy-paste of the assembly is a common cause.
- Redeploy the full assembly rather than a single Project, a partial deploy can leave the PrintService bean undeployed even though the calling Project deploys cleanly.
- Confirm the report design file referenced by the write step (the .rptdesign) is present in the same collection and hasn't been moved or renamed.
⚡ Quick fix
Redeploy the entire assembly (not just the failing Project) so the PrintService application is guaranteed to be loaded alongside the step that calls it.
✓ Permanent fix
Keep the PrintService application and every integration that calls it in the same collection and deploy them together going forward, rather than deploying dependent Projects independently.
