Hi,
I am trying to build an SDI adapter using Camel adapter according to the guide: Data Provisioning Adapter SDK Guide
adapters.xml:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Adapters>
<Adapter type="CamelForexAdapter" displayName="Camel Forex Adapter">
<RemoteSourceDescription>
<PropertyGroup name="configuration" displayName="Configuration">
<PropertyEntry name="sourceURL" displayName="Server URL" description="Forex source server" isRequired="false"/>
</PropertyGroup>
</RemoteSourceDescription>
<Capabilities>
CAP_SELECT
</Capabilities>
<RouteTemplate>forex-spring.xml</RouteTemplate>
</Adapter>
</Adapters>
forex-spring.xml:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://camel.apache.org/schema/spring
http://camel.apache.org/schema/spring/camel-spring.xsd">;
<bean id="sqlBean" class="com.sap.hana.dp.camel.ConvertSQLBean"/>
<bean id="http" class="org.apache.camel.component.http.HttpComponent">
<property name="camelContext" ref="camel"/>
</bean>
<camelContext id="camel" xmlns="http://camel.apache.org/schema/spring">
<route>
<from uri="direct:start"/>
<to uri="https://www.freeforexapi.com/api/live?pairs=EURGBP"/>
</route>
</camelContext>
</beans>
I have downloaded jar file with HttpComponent class and put it into folders: <dpagent>/camel/lib, <dpagent>/camel, <dpagent>/plugins
When I try to activate a Remote Source I get the error:
SAP DBTech JDBC: [403]: internal error: Cannot get remote source objects: Cannot find class [org.apache.camel.component.http.HttpComponent] for bean with name 'http' defined in file [/usr/sap/dataprovagent/camel/forex-spring.xml]; nested exception is
java.lang.ClassNotFoundException: org.apache.camel.component.http.HttpComponent cannot be found by com.sap.hana.dp.cameladapter_2.3.5
What did I miss? Should I register the jar somehow/somewhere?
I tried different versions of the jar, checked that it has the required class inside.
Don't please pay much attention to the route in Camel context, I really try as the first step make Camel Adapter see the HttpComponent class.

I close the question. The issue related to unresolved dependencies from the Camel Component.
It became obvious after setting the trace level to DEBUG.
