问题 I have a camel rest api. I was trying to create an IAM User using apache camel framework. The code is like so -> .post("iam-create-user") .route() .process(new Processor(){ @Override public void process(Exchange exchange) throws Exception { exchange.getIn().setHeader("CamelAwsIAMUsername", "new-user"); }) .to("aws2-iam://current-user?accessKey=insert&secretKey=insert&operation=createUser") .endRest(); I am getting this error java.lang.NullPointerException: null .

问题 I am trying to use the apache camel aws2 DynamoDB component to retrieve an item. In the docs, it is given that we can use an operation getItem in order to achieve this.

问题 I have a camel rest api which scans a DynamoDb table. The code is like so -> .post("dynamodb-scan-table") .route() .toD("aws2-ddb://user?accessKey=insert&secretKey=insert&region=us-east-1&operation=Scan") .endRest(); This returns all the items in my table. My problem is how to scan the table based on a certain condition. In the camel docs, it is given that there is a header CamelAwsDdbScanFilter which is of the type Map<String, Condition> needs to be set in order to achieve the solution for

问题 I have an Apache Camel v3.3 project that works fine as a stand-alone application but I'm struggling to deploy it to Tomcat. The error I get is: Jul 06, 2020 5:53:49 PM org.apache.catalina.core.StandardContext listenerStart SEVERE: Exception sending context initialized event to listener instance of class [org.springframework.web.context.ContextLoaderListener] org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from ServletContext resource [/<NONE>];

问题 I have a camel route that looks like the next one: from("direct:download") .pollEnrich() .simple("sftp://my.host:22/folder/?username=foo&fileName=${header.CamelFileName} &privateKeyFile=src/main/resources/privateSSHKey") .to("file://state/downloaded"); The file src/main/resources/privateSSHKey is an RSA private key. That works without a problem : JSCH (library used by Camel for the SFTP endpoint) manages to connect and download the desired file. The previous setup is ok while developing,

问题 I'm creating a REST Service with Apache Camel and CXF-RS, using the following tutorial: https://www.javainuse.com/camel/apache_camel_rest_cxfrs I've set up the code as shown in the tutorial and followed the steps correctly. After building the Maven project, I have successfully been able to install the bundle on Apache Karaf, using the SNAPSHOT file created. (A new Bundle ID was created). When I run the command to 'start' the newly created bundle, it seemingly works with no errors being shown.
