I use Seam 2.1.1.
Should I use this:
<pdf:document-store use-extensions="true" error-page="/missingDoc.seam"/>
or this:
<document:document-store use-extensions="true" error-page="/missingDoc.seam"/>
to setup document-store?
And for what is the pdf:key-store-config?
<pdf:key-store-config key-store="pdf.keystore" key-store-password="storepass" key-password="keypass" key-alias="pdfKey" />
Document store was moved from pdf to the main module. Use the one that is correct for your version of Seam.
The key store is for signing PDFs.
