First time user issues - Java compile errors and JVM config

Anonymous — Sat, 16 Nov 2024 04:30:16 GMT

I'm really wanting to get on board with this tool for many reasons, but early on it is somewhat frustrating. I understand that the installed JVM and configuration are important to a smooth experience. What exact version is required or are there specific versions to avoid? I'm having issue with running the demo code and get the issue below. I am simply trying to run the code at the bottom of this post which is supposed to tell me what version of the JVM I have installed - my way of troubleshooting.

For starters I installed the most current java runtime and had issues - studio wouldn't run - java error 13. Then I installed the most recent JDK SE and fixed the path issues myself. Open Studio seems to work fine. The code for the jobs seems to fail now. Any help is greatly appreciated.

Long term I want to build jobs and deploy on ubuntu to etl data from SQL server to a production MySQL instance. If anyone reading this can offer advice I'm all ears. Thanks!

Job compile errors

The method convertToJSONText(..........refers to the missing type List

Make sure your JVM setup is similar to the studio???? Any help here would be great!

At least job "OnBoardingDemoJob" has a compile errors, please fix and export again.

There may be some other errors caused by JVM compatibility. Make sure your JVM setup is similar to the studio.

Basic Settings:

Date date = new Date();
System.out.println(date);

System.out.println("\n---------- Environment Variables");
Map<String, String> env = System.getenv();

Hi,

Could you please use Java 8 and try to run the job again?

In case you are having multiple JRE versions, please go to Windows-> Preferences and tag the correct JRE version to Talend Studio as shown below.

Warm Regards,
Nikhil Thampi

Thanks for the help. The solution was to install the latest 64 bit version of the JRE and change the settings as recommended. This fixes the compile errors. Thank you!
