Exception in thread "main" java.lang.Error: Unresolved compilation problem: shadowfileinputtodelimitedoutput_0_1

Alematt — Fri, 15 Nov 2024 23:54:59 GMT

Hello,

I have been working on the same environment for several months with TALEND (TOS-DI-7.0.1) and it works fine. But since yesterday, when I want to create a delimited file (.csv), in step 3 of the wizard, the output window shows me:

Exception in thread "main" java.lang.Error: Unresolved compilation problem:

at project.shadowfileinputtodelimitedoutput_0_1.ShadowFileInputToDelimitedOutput.main(ShadowFileInputToDelimitedOutput.java:2258)

Erreur de prévisualisation. Des paramètres doivent être modifiés`

Note : Les erreurs de prévisualisation sont généralement liées à un mauvais paramétrage de l'encodage.

org.talend.commons.ui.swt.thread.SWTUIThreadProcessor$1.run(SWTUIThreadProcessor.java:74)

What is surprising is that other already created delimited files show the same errors. However, I haven't changed anything in my JAVA configuration (java 😎

Hi, @not specified not specified ,

it seem you have charset encoding issue : could you check in notepad++ for example in wich encoding is the original file ?

and in STEP 3 change to the appropriate charset encoding

Send me love and kudos

with a test csv file i can reproduce your error if i set a completely wrong file encoding :

Thank you Jeremy! 🙂

My file is encoded in UTF-8.

Upon reading the error message, I had already tried this approach, without success.

Also, my already created delimited files are in UTF-8, and it worked. Now when the wizard reopens on these same files, I have the error !! ..

you select ignore header, but you have only header

also you choose window cr Lf for row separator

so in talend you have to chose custom :"\r\n"

gjeremy1617088143 — Tue, 27 Jul 2021 13:13:59 GMT

could you send your example file?

Alematt — Tue, 27 Jul 2021 13:15:01 GMT

Yes indeed, I had not yet taken the time to modify this option, but that does not change anything.

I don't believe this is from the files, since it was working fine yesterday.

But I don't see what could have changed!

try to restart talend

I even restarted my entire machine, without success

gjeremy1617088143 — Tue, 27 Jul 2021 13:25:06 GMT

what is your jDK version ?

Could you please ensure JDK bin is included in your PATH environment variable and is being reached?

Alematt — Tue, 27 Jul 2021 13:50:23 GMT

I don't have JDK, but just java version

java -version

java version "1.8.0_131"

Java(TM) SE Runtime Environment (build 1.8.0_131-b11)

Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)

you can see it on where you have installed java.

it can be for example : C:\Program Files (x86)\Java\jdk1.7.0_45\bin

You could modify TOS_DI-win32-x86.ini (for window OS as example )to force Talend to plug with Java 1.8 and add these lines :

-vm C:\Program Files\Java\jdk1.8.0_xxx\bin

-vmargs

-Dosgi.requiredJavaVersion=1.8

I don't have JDK, only JRE version

And my TALEND configuration for JAVA

And i tried to add these lines, but i always have the same error! 😞

-vm C:\Program Files\Java\jre1.8.0_131\bin

-vmargs

-Dosgi.requiredJavaVersion=1.8

Hello,

Ensure proper version of JDK is installed. For v6 of Talend products JDKv1.8 is required instead of JRE.

Here is online documentation about: TalendHelpCenter: Configuring a JDK path to build Jobs

Let us know if it works for you.

Best regards

Sabrina

Hello Sabrina,

I took your advice in addition to Jeremy's.

But nothing helps, I still have the worries.

I usually back up my TALEND environment every two months. I came back to an old environment, and I still have the problem, I do not understand where it can come from ...

Hello,

Are you using Oracle JDK or openJDK?

Talend didn't add support for OpenJDK until V7.1.1 version. Have you tried to restart your machine to see if your V 7.0.1 studio works?

Best regards

Sabrina

The bit of the operating system needs to be the same as the JAVA version.

eg: windows 10 (64) + Java 8 (64)

If everythig worked the last day and now everything crash, you can suspect a windows update is causing your issue

Re: Exception in thread "main" java.lang.Error: Unresolved compilation problem: shadowfileinputtodelimitedoutput_0_1

Alematt — Wed, 28 Jul 2021 08:12:47 GMT

I downloaded and installed this one:

jdk-8u301-windows-x64.exe
