CONTEXT_E_NOJIT

CONTEXT_E_NOJIT is the failure HRESULT 0x8004E026 (signed decimal -2147164122, unsigned decimal 2147803174). Its severity bit is 1, facility is 4 (FACILITY_ITF), and the facility-specific code field is 0xE026.

The requested context operation depends on JIT activation that is not enabled

This HRESULT means the operation requires just-in-time activation in the current COM+ context, but that property is absent. JIT activation controls deactivation and transparent reactivation while a client continues holding a reference.

AllStat describes the result as “The requested operation requires that JIT be in the current context and it is not.” For CONTEXT_E_NOJIT, this wording identifies the immediate COM+ condition, while surrounding context and earlier events determine why it was reached.

Contract boundary for CONTEXT_E_NOJIT

A COM+ context can exist without JIT activation. The failure is therefore configuration-specific and should not be collapsed into CONTEXT_E_NOCONTEXT.

Causes that fit this specific result

The component implementation uses a JIT-dependent context feature while JIT Activation is disabled.
Deployment imported the class but did not preserve its component-level JIT setting.
The class was activated in a different COM+ application with weaker service attributes.
Transaction or synchronization settings were changed and no longer establish the expected JIT relationship.

Evidence to preserve before changing the system

Record application ID, CLSID, context ID, and the effective JIT, transaction, and synchronization settings.
Compare Component Services configuration with the deployment manifest.
Verify that activation occurred through the intended COM+ application.
Log the exact context operation that requires JIT rather than only the outer component method.

Diagnostic sequence

Confirm that the component is designed to be stateless across JIT deactivation and reactivation.
Enable JIT activation only when its lifecycle contract is appropriate.
Align transaction and synchronization settings because COM+ imposes dependencies among them.
Recycle the application and validate deactivation/reactivation behavior under load.

Retry and recovery

Correct the component configuration or remove the JIT-dependent operation. A retry in the unchanged context cannot add JIT activation retroactively.

What CONTEXT_E_NOJIT does not establish

The result does not mean JIT compilation failed; “JIT” here is COM+ just-in-time object activation. It also does not prove that transactions are disabled.

Difference from nearby HRESULT values

CONTEXT_E_NOTRANSACTION means the context has no transaction. CO_E_NOSYNCHRONIZATION indicates a component requires synchronization that was not configured.

Practical scenario

A component expects COM+ to deactivate it after setting the done bit, but a package migration disables JIT activation. The operation returns this code; administrators restore the JIT and synchronization attributes after confirming the class is stateless.

Developer and telemetry guidance

Spell out “COM+ JIT activation” in logs to avoid confusion with managed-code compilation. Deployment tests should assert the effective component attributes, not just successful registration.
