Positinal data that have many columns occurs the compile error.

Hi,
I am using the Java project by version 4.0.2.
I want to output the positinal data with 702 columns.
However, Talend has error
"java Code of a method longer than 65535 bytes"
(1)In MetaManeger
tFileInputPositionalProcess(Map<String,Object>)
(2)In Job
t...Input_1Process(Map<String,Object>)
Does Talend have the limitation in the number of columns of positinal data to be able ?

The positinal data with 702 columns
Fieldseparator:

Hi
There are so many columns in the job and lead to the size of final generated code exceed 65536 bytes.
It is a limitation of JVM(java.exe)!!!, see
http://java.sun.com/docs/books/jvms/second_edition/html/ClassFile.doc.html#88659
-->The amount of code per non-native, non-abstract method is limited to 65536 bytes by the sizes
As a workaround, try to reduce the number of column if possible.
Best regards
Shong

thanks shong ,

That. I also know.

It is impossible.

I question again.
Does Talend have the limitation in the number of columns of positinal data to be able ?

Hi
There is no limitation in the number of columns of positional data.
- if job is too complex, redesign with less components, do a more simple job.
- if job is already simple, please create a bug on our bugtracker and upload your job, we will try to find some ways to reduce the size of generated code for you.
Best regards

Hi emaxt6
Thank you for your comment.
I understand this is impossible to do it at present.
