Java API for working with digital signature.

[Former Member]

Hi,

I have to check whether a pdf form is modified since it is digitally signed, using a java program.

Are there any java APIs(provided by SAP) available for that?

Can I use IWDPDFDocument API in java program? I tried it but I am getting 'classnotfoundexception'.

Thanks,

Prabhakar.

may i know what service pack of SAP NetWeaver Developer Studio version are you using?

as the "IWDPDFDocument" is only available on SAP NetWeaver 2004S SPS 10 and above

and you just need to import either this two class

com.sap.tc.webdynpro.clientserver.adobe.api

com.sap.tc.webdynpro.clientserver.adobe.pdfdocument.api

hope this information could help you
