How can I parse SOAP headers within apache camel processor from apache camel cxf endpoint in POJO mode:
<cxf:cxfEndpoint id="MyWS" address="http://localhost:8080/services/MyWS" serviceClass="tmp.MyWS" />
<route>
<from uri="cxf:bean:MyWS" />
<process ref="MyProcessor" />
</route>
On the official apache camel cxf website I found an example how to set headers, but there is no examples about getting them. How can I get messageId value. My SOAP request looks like that:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:inv="http://inv.org">
<soapenv:Header>
<inv:messageId>111</inv:messageId>
</soapenv:Header>
<soapenv:Body>
...
</soapenv:Body>
</soapenv:Envelope>
In the Camel Route builder we will get the SOAP Header using simple componenent, in the below example I am apply cbr using SOAP operation name i.e.
from("cxf:bean:xyz-ws?dataFormat=POJO").routeId("xyz-ws").log( "This is ${in.header.operationName} operation called...." )
.log( "Entering inside the Choice with operation....${in.header.operationName}")
.when(simple("${in.header.operationName} == 'getDataFromDictionary'"))
Hope this is helpfull.

I'm trying to use Apache Camel's Http4 component to connect to a HTTP URL that needs Basic authentication. I'm setting credentials from a camel processor through Exchange.HTTP_QUERY header. I configure my route like this:
<?xml version="1.0" encoding="UTF-8"?>
<blueprint ...>
<bean id="myProcessor"
class="com.myCompany.Bean"
factory-method="myProcessorBean">
</bean>
<camelContext id="myContext" xmlns="http://camel.apache.org/schema/blueprint">
<route id="myRoute>
<from uri="activemq:queue:myQueue" />
<process ref="myProcessor" />
<to uri="http4://oldhost"/>
</route>
</camelContext>
</blueprint>
and my processor looks like:
public void process(Exchange exchange) throws Exception {
String user = getUserFromDB();
String pwd = getPasswordFromDB();
String queryParameters = "authMethod=Basic&authPassword="+pwd+"authUsername="+user;
exchange.getIn().setHeader(Exchange.HTTP_QUERY, queryParameters);
exchange.getIn().setHeader(Exchange.HTTP_URI, "api.abc_company.com/service/to/consume");
....
}
It results in:
Error myContext: org.apache.camel.http.common.HttpOperationFailedException: HTTP operation failed invoking https://api.abc_company.com/service/to/consume?authMethod=Basic&authPassword=xxxxxx&authUsername=test with statusCode: 401
It seems that password was changed to xxxxxx but I'm not sure.
When I try hardcoding user and password in the URI it works well, however I need a way to set these values programmatically due to user and password are stored it the DB.
"authMethod=Basic&authPassword="+pwd+"authUsername="+user;
You'll need to at & between each uri parameter. You're missing one after password.
Try:
String queryParameters = "authMethod=Basic&authPassword="+pwd+"&authUsername="+user;
Also you should define credentials in producer endpoint URI http4://oldhost?authMethod=Basic&authPassword="+pwd+"&authUsername="+user instead of header: Exchange.HTTP_QUERY.
If you want to do this in your processor you can try to set Authorization header manually with value basic <credentials> where <credentials> is base64 encoded username:password.
Failed invoking https://api.abc_company.com/service/to/consume?
If you want to connect to https site use https4://
I'm trying to expose a JAX-WS Webservice (an annotated Java class) using Camel. When using a single parameter the Web service replies correctly. On the other hand when using as parameter an Object or multiple parameter it does not work.
Here is the blueprint I have deployed on JBoss Fuse:
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0" xmlns:camelcxf="http://camel.apache.org/schema/blueprint/cxf" xmlns:cxf="http://cxf.apache.org/blueprint/core" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.osgi.org/xmlns/blueprint/v1.0.0 http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd http://camel.apache.org/schema/blueprint/cxf http://camel.apache.org/schema/blueprint/cxf/camel-cxf.xsd http://cxf.apache.org/blueprint/core http://cxf.apache.org/schemas/blueprint/core.xsd http://camel.apache.org/schema/blueprint http://camel.apache.org/schema/blueprint/camel-blueprint.xsd">
<camelcxf:cxfEndpoint id="demo-target-cxf" address="http://localhost:9000/SourceExample/hello" serviceClass="com.sample.SourceExampleWSImpl" endpointName="SourceExamplePort" serviceName="SourceExampleService" />
<camelContext xmlns="http://camel.apache.org/schema/blueprint" id="fuse-demo-route-exmple-cxf">
<route id="demo-target-cxf">
<from uri="cxf:bean:demo-target-cxf" />
<transform>
<simple>${in.body}</simple>
</transform>
<log message="Message input: ${in.body}" />
<removeHeaders pattern="CamelHttp*" />
</route>
</camelContext>
</blueprint>
Here is the Web Service implementation class:
#WebService
public class SourceExampleWSImpl {
#WebMethod
public int getTotal(int x, int y) {
return x+y;
}
}
The bundle ic correctly deployed on JBoss Fuse. When invoking the Web service, only the first parameter is evaluated. So for example, invoking with arguments 1 and 4:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:sam="http://sample.com/">
<soapenv:Header/>
<soapenv:Body>
<sam:getTotal>
<arg0>1</arg0>
<arg1>4</arg1>
</sam:getTotal>
</soapenv:Body>
</soapenv:Envelope>
returns:
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<ns2:getTotalResponse xmlns:ns2="http://sample.com/">
<return>1</return>
</ns2:getTotalResponse>
</soap:Body>
</soap:Envelope>
Any idea how to fix it ?
Thanks
Do you mean the expected output should be
1 + 4 = 5 because the following code should be called?
public int getTotal(int x, int y) {
return x+y;
}
If so that does not happen, when you use camel-cxf as a bean then the bean only defines the contract, the code in the implementation is not in use.
If you just want a standard SOAP-WS and write java code that builds and process the SOAP requests/response then just use plain CXF.
I have a task to handle all incoming messages within the route and save them to database.
My route starts with webservice (camel-cxf), and then process to ejb and return soap response.
I've decided to use camel-sql component. As far as I don't have any problems with logging incoming message:
<camelContext id="InstitutionContext" xmlns="http://camel.apache.org/schema/spring">
<onException>
<exception>org.example.MyException</exception>
<continued><constant>true</constant></continued>
<to uri="bean:myExceptionHandler?method=handle" />
</onException>
<route id="InstitutionRoute" >
<from uri="direct:start" />
<to uri="sql:insert into translog(id,type,data) values(2,'IN',#)" />
<split>
<tokenize token="\n" />
<unmarshal>
<csv delimiter=";" />
</unmarshal>
<process ref="InstitutionProcessorTest" />
</split>
<to uri="bean:myExceptionHandler?method=checkErrors" />
</route>
</camelContext>
but I don't have idea how to handle exceptions and save them in the form of SOAP message.
<onCompletion onFailureOnly="true">
<to uri="sql:insert into translog(id,type,data) values(2,'ERROR',#)" />
</onCompletion>
but it saves original message in data column. Is there any body who can help?
I might be misunderstanding the question but it looks you are trying to save the SOAP message in XML format if there is a exception.
By default the dataFormat for CXF is POJO meaning it sends a POJO around the camel route i.e. the SOAP XML is converted to a POJO.
Two options come to mind:
Set the dataformat to message or payload. This will send the XML message across the camel route instead of a POJO
Marshall the POJO into a XML message and save it.
I have created a simple cxf web service. following is the body of soap message
<soapenv:Body>
<bean:getRTOEmployeeSalary>
<!--Optional:-->
<bean:arg0>sdf</bean:arg0>
</bean:getRTOEmployeeSalary>
</soapenv:Body>
My requirement is to extract the value of arg0 in my camel context file. i.e. i want to log the value of arg0. Please help me on this
<route routePolicyRef="loggingInInterceptor">
<from uri="cxf:bean:rtoemplyeeService"/>
<setHeader headerName="exchange">
<spel>${exchange}</spel>
</setHeader>
<log message="value of arg0======== "/>
<convertBodyTo type="java.lang.String" id="stringInput"/>
<bean ref="rtoEmpBean" method="getRTOEmployeeSalary" beanType="rtoEmpBean" id="govtRTOEmp"/>
</route>
I need to use the value of arg0 here.
We can use camel provided spring expression language to extract the value from exchange object. Since exchange object also resides in spring container.
below will be code src to extract the value of arg0 in camel context-
<setHeader headerName="arg0">
<spel>#{exchange.in.body.get(0)}</spel>
</setHeader>
This will set the value of arg0 of soap message in a header named arg0.

I am Ashish from Mumbai and very new to Apache Camel.
Currently I am building a route in XML which will scan the SOAP request and will redirect the request to appropriate URI.
My Soap request isn as follows:
<service xmlns="http://ws.madcomum.comprova.com">
<request>
<keysValues>
<item>
<bytesValue
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:nil="true"/>
<dateValue
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:nil="true"/>
<doubleValue
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:nil="true"/>
<key>validatesOriginIntegrity</key>
<longValue
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:nil="true"/>
<stringValue>z4x/FOOR+EPQ0vD9+itPSCBeNR4=</stringValue>
</item>
</keysValues>
<actionId>1</actionId>
<clientId>ARGO</clientId>
</request>
</service>
From this SOAP envelope, I want to parse out value of actionId tag using Camel Route.
If actionId has value of 1 then route must be redirected to callService else to another service.
I developed logic of route as folows:
<route>
<from uri="cxf:bean:comprovaWS?dataFormat=MESSAGE" />
<when>
<xpath>//actionId=1</xpath>
<to uri="log:input" />
<to ref="callService" />
<to uri="log:output" />
</when>
<otherwise>
<to uri="log:input" />
<to ref="otherService"/>
<to uri="log:output" />
</otherwise>
</choice>
</route>
But this logic is not working.
Is there any error in my route?
Though I am Java guy, I don't want to use Java here. I want to rely on Camel itself.
Please help me ASAP.

Ashish
When you use xpath then 95% of the times when people have trouble its often due to namespaces. Your SOAP message is defined using a namespace - "http://ws.madcomum.comprova.com". The xpath expression must use this namespace to make it work.
See more details at: http://camel.apache.org/xpath, there is an example at the section Using XML configuration
Also as you use CXF in MESSAGE mode, then read about stream caching as the message is stream based: http://camel.apache.org/stream-caching.html
