Could not find or load main class

[Anonymous]

I have  already tried the solutions recommended by other posts on the community:

- install path with no spaces

- running on java 1.8_77

- cleaned up work space

- fresh install of talend

None of the above have resolved my issue. I am running talend on my local machine

i am running talend studio for big data 6.3.0

with 

java jdk is 1.8_77

talend path is  

/Users/me/Documents/Software/TOS_BD-20161026_1219-V6.3.0/TOS_BD-macosx-cocoa

can some one help as i have exhausted all possible solutions.

let me know if any other information can be provided

Solution FOUND !!

It seems i have added and extra java library in the extensions folder where the java install path is. somehow this effected talend although im not sure why. i have now removed this extra library and it works again.

just to add to the solution, Any extra error or hints can be found by changing from integration mode (top right icon ), into java mode by clicking on the little icon at the top to change modes

You could use java 9 by adding the line 

--add-modules=ALL-SYSTEM 

to TOS_DI-20170623_1246-V6.4.1\plugins\org.talend.rcp_6.4.1.20170623_1246\eclipse.ini

-vmargs
--add-modules=ALL-SYSTEM

and to TOS_DI-win-x86_64.ini

-Dosgi.requiredJavaVersion=1.8
--add-modules=ALL-SYSTEM

Hi All,

I have an issue "could not find or load the main class" when I run the job from ide, I have instructed to check java installation path and environment setup everything, I have no idea to resolve this,

I have checked my installation path, there are no blank spaces,

this is the below environment setup,

JAVA_HOME - C:\Program Files\Java\jdk1.8.0_162\

JRE_HOME- C:\Program Files\Java\jre1.8.0_162\

TALEND_HOME -C:/Talend/6.4.1

path - C:\Program Files\Java\jdk1.8.0_162\bin   

operating system - Windows 8.1 or Windows Server 2012 R2 

can you have an alternative way to resolve this?

Hello,

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

Error: Could not find or load main class" . is there any alternate way to resolving this?
