             Summary: camel-web3j - align Exchange header constant names with 
Camel naming convention
                 Key: CAMEL-23578
                 URL: https://issues.apache.org/jira/browse/CAMEL-23578
             Project: Camel
          Issue Type: Improvement
          Components: camel-web3j
            Reporter: Andrea Cosentino
            Assignee: Andrea Cosentino
             Fix For: 4.21.0


The Web3j header constants in 
{{org.apache.camel.component.web3j.Web3jConstants}} use uppercase string values 
that do not follow the Camel naming convention. The most security-relevant ones 
drive blockchain dispatch and transaction parameters:

* {{OPERATION = "OPERATION"}} - dispatch across ~80 RPC methods including 
{{eth_sendTransaction}} / {{eth_sign}}
* {{FROM_ADDRESS = "FROM_ADDRESS"}} / {{TO_ADDRESS = "TO_ADDRESS"}} / {{VALUE = 
"VALUE"}}
* {{SIGNED_TRANSACTION_DATA}}, {{SHA3_HASH_OF_DATA_TO_SIGN}}
* Plus ~25 more RPC argument headers ({{GAS_PRICE}}, {{GAS_LIMIT}}, {{NONCE}}, 
{{DATA}}, {{TOPICS}}, {{PRIVATE_FOR}}, {{PRIVATE_FROM}}, ...)

Rename to {{CamelWeb3j<Name>}} across all constants.

h3. Fix shape

Rename the *string value* of each producer-read header constant to 
{{Camel<Component><Name>}}; keep the Java field name unchanged so routes that 
reference the constants symbolically continue to compile and run. Update tests 
that use the literal string values; regenerate component catalog JSON and docs; 
add an upgrade-guide entry in {{camel-4x-upgrade-guide-4_21.adoc}} (and 
matching 4_18 / 4_14 for backports where the component existed in those 
branches).

h3. References

* Tracker: CAMEL-23577
