Anonymous — Sat, 16 Nov 2024 09:07:21 GMT

Hi All,

I would like to know which java version is used to develop TAC web application.

I am facing an issue when deploying TAC war file in apche-tomcat.

Please have details below:

1) Java

java version "1.8.0_11"

Java(TM) SE Runtime Environment (build 1.8.0_11-b12)

Java HotSpot(TM) 64-Bit Server VM (build 25.11-b03, mixed mode)

2) apache-tomcat 8.5

3)Error message

java.lang.UnsupportedClassVersionError: org/talend/administrator/common/persistence/servlet/EmbeddedDbCloser : Unsupported

major.minor version 52.0 (unable to load class org.talend.administrator.common.persistence.servlet.EmbeddedDbCloser)

I have found the issue is related to Java version conflict.

Hi,

I am not installed jobserver. I have installed apache-tomcat manually and deployed tac war file.

I am using "java version 1.8.0_11".

Thanks,

Hello,

The JVM parameters should appear in the JVM parameters tab in Job conductor.

Best regards

Hi Xdshi,

Thanks for your response. I am not expecting talend job java vesrion.

Actually i would like to know on which java version talend administrator was build. So that i can install same java version in my machine to deploy tac in apache-tomcat. I am getting version conflict error.

Hi All,

I found the Java version is used for developing TAC application in the following path.

go to the directory <apache_tomcat_path>/webapps/org.talend.administrator-6.4.1/META-INF/ and open a file "MANIFEST.MF" in this you will see Java version as follows.

Manifest-Version: 1.0
Ant-Version: Apache Ant 1.7.0
Created-By: Apache Maven 3.2.5
Archiver-Version: Plexus Archiver
Built-By: jenkins
Build-Jdk: 1.8.0_40

Note : <apache_tomcat_path> is where you installed apache-tomcat server.

Thanks,

A Ravi Kumar
