help on SEDA endpoint jakarta.mail.FolderClosedException from IMAP

[Amarnath Reddy]

Hi,

IIn the below route configurations I am reading the email from Gmail and
then directing to a Cmel bean using seda endpoint. I close the connection
on every poll as a best practice.

While reading the email body in the bean 'imapPreProcessor' I get an
exception as below. Kindly help me.

Exception:
Inside process Error handler with exception {}
org.apache.camel.StreamCacheException: Error during type conversion from
type: jakarta.mail.internet.MimeMultipart to the required type:
org.apache.camel.StreamCache with value
jakarta.mail.internet.MimeMultipart@533502fd due to
org.apache.camel.TypeConversionException: Error during type conversion from
type: jakarta.mail.internet.MimeMultipart to the required type:

             "?accessToken=" + OAUTH_ACCESS_TOKEN +
             "&oauth2.enabled=true" + // Enable OAuth2 authentication
             "&disconnect=true" +
             "&closeFolder=true" +
             "&consumer.delay=5000" + // Check for new emails every 5
seconds
.routeId(WSCommonConstants.IMAP_ROUTE_ID)
.autoStartup(true)
.choice()
.when(method(PatternValidator.class, "isValid"))
.to("seda:gotoalart")
.otherwise()
.to("seda:gotoabcd")
.end();// Closes primary choice block;



from("seda:gotoabcd?concurrentConsumers="+commonabcdConsumers)
    .routeId("emailProcessChain")
    .autoStartup(true)
    .process(emailValidationProcessor)
    .choice()
    .when(simple("${header.validatedUser} != null && ${header.action} ==
null"))
    .process(imapPreProcessor) // StreamCacheException is coming here
    .otherwise()
    .process(authenticationFailedProcessor)
    .to("direct:gotothirdstep");
