NullPointerException: while trying to invoke the method java.lang.String.length() of a null object loaded from local variable 'str'

[Former Member]

Dear Team,

This is basically FTP to FTPS scenario where at Receiver communication channel I'm facing below error:

Error when getting an FTP connection from connection pool: Unable to create a new pooled resource : NullPointerException while trying to invoke the method java.lang.String.length() of a null object loaded from local variable 'str'

PI fetches the text file from ECC application server and places into the target application folder wherein we face the error at receiver communication channel.

Please help. Many Thanks...!!

Looks like an issue while connecting to the target server.

Can you share screenshots of your channel configuration and the error?

Have you configured certificates correctly for FTPS?

Are you using variable substitution in your channel?

Make sure the FTP server is added to your network firewall..

Hi Ramkumar,

Will there be problem with java version. I'm using java 1.4.2.

Hello Ram,

Please find below screenshots of receiver channel.

will there be any issue with Java version.

Currently it is running on Java web start 1.4.2.

Is it required to upgrade to 6 or 7 to avoid Null pointer exception errors.

Hi Rajesh,

Do you have any additional modules setup in the module configuration?  If those get saved out of order then you can sometimes get errors like this in the runtime.

Hello Rajesh,

Just to cross-check, have you imported the certificate in X.509 type and not in Binary type ?

Hello Rajesh,

Please note that certificates are in Binary or X.509 format.

from the screenshot of the receiver channel I can see that the transfer mode is Binary, however on the other hand you have also checked the checkbox for X.509 certificate. Here I can suggest you to uncheck that check box.
