Java error when generating report in tJasperOutput

kedy2she — Fri, 17 Nov 2017 04:59:45 GMT

I tried to generate a pdf report using tJapserOutput however I face an error as shown below. Firstly, we does it point to C:\Talend\TOS_DI-Win32-20170623_1246-V6.4.1\report2_1510843960965_974411.java to compile a a file that doesn't exists and is not defined in the tJasperOutput component. Besides that, I have tried pointing the latest version of JDK but the same error occur. Please assists. Thank you in advance.

Are you using 32 bit talend application? TOS_DI-win32-x86.exe for 32 OS and TOS_DI-win-x86_64.exe for 64 bit(Windows, for example)

Hi Kedy2she,

I am facing the same issue. You are solving this issue, by setting JAVA_PATH variable in environment variable.

Is it necessary to declare path variable?

I have added only JAVA_HOME.

So please tell me the exact way.

Thnx in advance.
