Java Version Problem

javvaji — Fri, 14 Jul 2017 16:46:46 GMT

Hi,

We have talend jobs which are built in Talend 5.6 and java version 1.7. Now i imported the same jobs in Talend 6.1 and i am using java 1.8. when i am trying to build the job i am getting Below error.

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

Hi,

What is your JDK Compliance level in Studio Java Compiler preferences? Is it set to 1.7 or 1.8?

Hi,

Thanks for your reply.

It is set to 1.7

Hello,

Could you please check if you correctly use JDK 1.8 (Installed JREs; Compiler and Talend Java Interpreter)?

Can you successfully execute a new job created in V 6.1 studio?

Best regards

Sabrina

Hi,

Thanks for your Reply.

I am using jdk & jre 1.8 only. I am able to create a new job and can execute it.

Jre 7 also installed. But in talend i am using jre 1.8 only.

Thnaks,

Bharath.

Hi,

Does this issue only repro on these talend jobs which are built in Talend 5.6?

Best regards

Sabrina

Re: Java Version Problem

Yes.

I created a sample job in Talend 6.1 and tried to build. It build successfully.

Thanks,

Hi,

The issue has been resolved.

Issue is i am getting some encrypted code in all password fields in jobs, so we need to remove it and need to replace it with new value/variables. Below is the code highlighted where i am getting encrypted code. And also attaching the screen shots of it.

final String decryptedPassword_tMysqlConnection_1 = 4D9onkGJm3dYUhjgejgz7nPhaUwbHXL49PeroXRnhOo=Encrypt;
String dbPwd_tMysqlConnection_1 = decryptedPassword_tMysqlConnection_1;

Thanks,

Bharath.

Yes that feature was added in later version. Any attribute of type password will encrypt the password. If you use context variable though, it should just use the value of the context variable.

Re: Java Version Problem

javvaji — Wed, 19 Jul 2017 17:08:10 GMT

Hi,

But here the context variable is also encrypting.

Thanks,

Bharath.

Do you have screenshots of export of the job? Yes looks like something went wrong here. But it should be easily rectifiable.

Hi,

After importing Talend 5.6 job into Talend 6.1 the password field in the component has been encrypted.

Here i have used context variable in password field, but still is encrypted.

Below is the code. And also attaching the screen shots after importing and without changing the password field

final String decryptedPassword_tMysqlConnection_1 = 4D9onkGJm3dYUhjgejgz7nPhaUwbHXL49PeroXRnhOo=Encrypt;
String dbPwd_tMysqlConnection_1 = decryptedPassword_tMysqlConnection_1;

Yep something went wrong there. Maybe there are patches for this on 5.6. You need to contact our support for this, if you have a support login.

You should click on the button with 3 dots, and then specify your context variable without " ". If you specify " " the studio thinks it is a string and encrypt it. If you don't, it knows it is a variable.

Yes exactly.

I followed the same thing it worked.

Thanks for your reply.
