two custom components cannot run one job

[Anonymous]

Hello,

I have develop two custom components (name: Producer and Register) in the same family (name: IBIT) and category (big data)  with version component-api 1.1.4 and talend-component-maven-plugin 1.1.5. The two components run single in the job but not together. I get the error:

Exception in component IBITProducer_1 (test)
java.lang.IllegalArgumentException: Can't find IBIT#Producer
at project.test_0_1.test$1tWaitForFile_1Thread.lambda$0(test.java:1277)
at java.util.Optional.orElseThrow(Optional.java:290)

My job look like:

What can I do?

Are the components packaged in separated jar files ? if yes, this is not supported for the moment for the same family. So please package all the components of the same family in one single jar.

yes they are seperated eclipse/maven project. Can I have seperate maven/eclipse project and pack to one jar?

Hi

Currently we enforce a single "component" - understand this as deployed component module - to own a family to guarantee we have some interoperability between components.

In next version - 1.1.6 - we will enable to have a component depending on another one and deploying both with the registration of the root component but still not to deploy 2 component modules in the same family for the same reason.

Please use two families - but it can use the same category - or merge them both through your build - you can always do a shade of both modules and deploy that.

ok now I do not receive this error but the components doesnt start. Either IBITRegister starts (this module produces messages at regular intervals), but then twaitforfile does not respond. Only if I deactivate the module IBITProducer twaitforfile reacts when new files arrive.

is the IBITProducer component correctly receiving and handling the records from the tWaitForFile ?
Can you please debug your component and see if the component is working correctly.
Here is a chapter from the documentation explaining how to debug https://talend.github.io/component-runtime/main/1.1.7/studio.html#_debugging_your_custom_component_i...

yes because If I deactivate IbitRegister_1 and tMomOutput_1 the tWaitForFile and IBITProducer works correctly. It always works only one.

Hi,

I am creating custom component using Talend component starter kit . I am trying  to get values of talend paramters in service.java. please help me get values directly,gettter methods of datastore giving null values.

I need to get below screen shot parameters values directly in service.java.

these ElementParameterParser.getValue() method is usefull for jet frame work.

String serverAddr = ElementParameterParser.getValue(node, "__SERVERADDR__");
String port = ElementParameterParser.getValue(node, "__PORT__");

thanks,

venkat.

Hello @Venkat_C ,

you get it in the component (which is intantiated per parameter) and you propagate it to the service through a standard parameter passing pattern, you don't inject into a service parameters because services are shared between components (single instance per JVM).
