I'm trying to install an SSL certificate for a Java servlet framework. I have 3 files: the private key (PEM), certificate file (PEM) and CA bundle (PEM). When I run:

openssl pkcs12 -export -in server.crt -inkey server.key -certfile server.crt -out server.p12 -CAfile server.ca-bundle -chain

...in order to get the p12 file that I can use to create the Java keystore, it fails with the following error:

Error unable to get issuer certificate getting chain. 

Elsewhere, I have successfully setup 2 apache servers using the same key, certificate and CA bundle files and there are no problems. Why might I be getting this error?

I found (the|a) solution to this problem on this blog post. From the post:

After a bit of testing, I found that you need to make a new CAfile to be used, that combines the cacerts file from the openssl distribution and the intermediate.crt file...

...which is:

cat your-server-bundle /etc/ssl/certs/ca-certificates.crt > allcacerts.crt

...then use allcacerts.crt (or whatever you call it) as the parameter to the -CAfile option in the openssl command.
