Encountered the following error even though all the attached jar files have been added in the Routine Libraries including commons-logging-1.1.3

Additional Details

1) Talend version 7.3.1 was downloaded from the following webpage:

2) The application is being executed using jdk-11.0.10 through the following command. (It was previously working on jdk-15.0.1; but after encountering Java error after re-installation, it is now working on the lower JDK version 11.)

D:\>TalendStudio\Talend-Studio-20200219_1130-V7.3.1\Talend-Studio-win-x86_64.exe -vm TalendStudio\jdk-11.0.10\bin

3) A ParameterStore_Cred was created in the Repository under Code > Routines (Code used is in attached file, ParameterStore_Cred.java)

4) The Routine Libraries of ParameterStore_Cred was edited to add the JAR files from attached jar_files.zip

5) The sample Talend job has the following components:

6) The tJava_1 component contains the following line of code:

String str=ParameterStore_Cred.getParameter(context.parameter_store);

System.out.println(str);

globalMap.put("key", str);

7) The Target Execution of the job is a Custom Job Server in Talend cloud through AWS.

Hello,

Could you please clarify in which Talend version/edition you are? Have you tried to use a tLibraryLoad component to force packaging the lib to see if it works?

Best regards

Hi Sabrina,

Thanks for your reply. I have updated the details above with additional information; including Talend version/edition. We do not have any requirement to use a tLibraryLoad component; so I did not used that.

Best regards,

Sherwin

Hello,

In the module view, all jar relative to your components are installed successfully in studio?

Here is online documentation about: TalendHelpCenter: Installing external modules manually using the Modules view.

Best regards

Yes. The modules for my Talend job components were all successfully installed in Talend Studio. I added additional jar files in the libraries of the routine code; but Talend can't seem to find the class associated to it.

I have also tried the following; but still has similar NoClassDefFoundError:

Talend Studio menu -- File -> Edit Project Properties -> Build -> Click on Maven -> Click on 'Force full re-synchronize poms'
Used tLibraryLoad with all the same JAR files added to the routine code.
