Willem Jiang commented on CAMEL-1431:
-------------------------------------
Hi Charles,
Clause's Java DSL will set the out message's body with the instance of
OutputReportIncident,
{code}
// return OK as response
.transform(constant(OK));
{code}
Because Camel Spring's <constant>, <simple> tag don't support the hold the
bean's instance,
so we can use the <method> to return an instance of OutputReportIncident for
<transform> to use.
Basicaly, the <method> tag is mapped into MethodCallExpression in Java, the
expression
value is the method return value.
You can find the magic from the package of org.apache.camel.model.language in
camel-core.
For the java.lang.IllegalStateException, I wrote a comment in CAMEL-1427,
please check it out.
BTW, I also write a Spring configuration file which is based on Clause's
example in CAMEL-1465,
You may take it as an example.
