    As your using DC .

    You have to add the jars in external library DC.

    And create public part for that and should declare that DC as used DC in the DC which you are using the export to excel functionality.

    Note:- create public parts of both SDA and API type.

    Could you please let us know which version are you using.

    Thanks & Regards,

      It's not the problem with your DC. The error is coming because, the library is missing at server.

      For this, you have to create J2EE library project ,add jxl.jar to it and deploy it in server. as follows

      1: choose File->new->project->other->J2EE Server Component-->

      2: select 'Library' and click on 'Next'

      3: Give sample name 'JExcelLib' and click on 'Finish'

      4: Now goto navigator, copy jxl.jar from your pc and paste it into your project 'JExcelLib'

      5: Now goto J2EE explorer, right click on 'JExcelLib' and select 'Build Library Archive'.

      6: Right click on the .sda file that is generated and select 'Deploy To J2EE Engine'
