Http4 endpoint throws UrlRewrite NoClassDef

Hi all,

I’m moving http routes from Camel 2.x to 3.x.
Main dependencies are
Camel 3.4
SpringBoot 2.2.7-RELEASE
Spring 5.2.6-RELEASE

The http endpoints are configured at runtime and injected into Spring context.

So, when a message is routed to an http endpoint I get this exception:


Caused by: java.lang.NoClassDefFoundError: org/apache/camel/http/common/UrlRewrite

       at org.apache.camel.component.http4.HttpComponent.createEndpoint(HttpComponent.java:237)

       at org.apache.camel.support.DefaultComponent.createEndpoint(DefaultComponent.java:237)

       at org.apache.camel.impl.engine.AbstractCamelContext.doGetEndpoint(AbstractCamelContext.java:846)

       at org.apache.camel.impl.engine.AbstractCamelContext.getEndpoint(AbstractCamelContext.java:773)

       at org.apache.camel.support.CamelContextHelper.getMandatoryEndpoint(CamelContextHelper.java:73)

       at org.apache.camel.support.ExchangeHelper.resolveEndpoint(ExchangeHelper.java:114)

       at org.apache.camel.support.ExchangeHelper.resolveEndpoint(ExchangeHelper.java:92)

I cannot find any UrlRewrite class/interface in Camel 3.x libraries (only camel-http-commons 2.x seems to have one)
Looking at the stacktrace I don’t understand if I have some dirty dependency tree since from my understanding http4 package was renamed to http right?(https://camel.apache.org/manual/latest/camel-3-migration-guide.html)

Can someone point me to the right direction to solve this issue?

Thank you

Riccardo

Thank you for your reply.
I solved the issue, it was my fault. I had an old camel-http4 dependency (2.x) in the classpath.
I changed this dependency to camel-http (3.x) and worked!

Regards

Riccardo

    Hi Riccardo,

    URL rewrite is deprecated, last version 2.25

    https://camel.apache.org/manual/latest/camel-3-migration-guide.html 


    you must use real proxy to do that,  like NGINX or HTTPD Apache.


    Hope is help!
