Hi,
Are you using oracle java 8? Does this issue repro on all your jobs or a specific job?

I had the same problem and I found that the Preferences were set up for the wrong JDK a java 7 JDK in my case). It can be fixed by going to Window > Preferences > Installed JREs, selecting Edit and browsing for the appropriate JRE (jdk1.8.0_40 in my case.

I have the same issue. win 10. java 8_91 and talend 6.2.1...
Window > Preferences > Installed JREs seems to be ok.
what else can cause this error while trying to add excel to metadata?
thanks

Hi,
Could you please try to jre 1.8.0_51 instead? It seems that there is something wrong with jre 1.8.0_92.
Let us know if it is Ok with you.

Hi everyone,
I had same issue and solved by just moving JDK path to the beginning of PATH system variable.
Now my PATH var starts with:
"C:\Program Files\Java\jdk1.8.0_51\bin;C:\ProgramData\Oracle\Java\javapath;..."
- Win7Pro + JDK 1.8.0_51 (x64)
- TOS ESB 6.3.0 ( Window > Preferences > Installed JREs only shows 1.0.0_51 )

Solutions:
1. Check your Java (JDK and JRE) Installed properly
2. Your Java version and Talend version is both suitable or not
3. In the Environment variable > System variable Java JRE path should mention on first (Start's from Java to other paths)
4. Check your Windows > Preferences > Java > Installed JRE's > showing java path or not. It must show.
I hope above list of steps help you to fix preview error. I resolved by above steps.
Thanks,
