com.interwoven.cssdk.common.CSException: Bad write in server skeletons(Internal transport error)

Hi,

I'm receiving the following error when trying to run the OOB example "GetClientForTrustedUser" on the TeamSite server command line

I setup a certificate using openssl. Not sure where I am going wrong.

Would appreciate any help if someone has got this to work.

Thanks,

Alistair

What's the command you're using, and what properties are you passing in?

Versions and env info?

The version of TS being used is 7.2.1 on Red Hat 5.6

Rick Poulin

I vaguely remember there's a trick to remote execution with the CSJavaFactory.. gonna look that up, but while I do, can you confirm that this (remote execution) is what you intend your final code to do? There's much easier ways to hook into TS if your use case allows...

There was a servername mismatch. Corrected that and now I receive the following.

This is not remote execution. The command is being executed on the server itself.

Rick Poulin

It's remote from the perspective of your code not executing within the app itself but rather opening a HOPI connection from outside of it.

Do your local ssl certs match what's in TeamSite/servletd/conf/ssl_cert ?

abgi2009

The local ssl certificate generated does not match the one in TeamSite/servletd/conf/ssl_cert.

Rick Poulin

Well that's probably your issue. The server doesn't know how to trust you if the certs don't match.

abgi2009

I tried copying the certificate from the ssl_cert folder into my local folder but doesn't work.

Not sure how to get them to be the same or refer to the same certificate.

Rick Poulin

Did you copy the whole folder or just one file?

Are you able to connect and work on your server over https? (in your browser)

Also, given the way you're invoking the class, commons logging should default to SimpleLog, which means adding this parameter to your command (before the class name) should give you more verbose output:

-Dorg.apache.commons.logging.simplelog.defaultlog=debug

abgi2009

I tried copying the whole folder, tried repointing to that folder but nothing worked.

I think the https connection is not configured correctly. Because when I connect via https I get the warning "The site's security certificate is not trusted!". Clicking on "Proceed Anyway" logs me into TeamSite though.

Adding the additional debugging line I get the following:

The certificate not being trusted shouldn't be an issue. I've never had to change the certs unless the organisation insisted for security reasons. Besides, since your client-side has the same certs, the hopi connection should consider them 'trusted'.

I'm out of ideas for what to suggest, short of moving pieces and trying to narrow the issue. If you point to any other valid directory that doesn't contain your ssl certs, does the same thing happen (maybe it's not finding them correctly)? Can your target be reached on port 8899? Is there anything on the server that would prevent even localhost communication to that port? Is there anything in the server logs relevant to this?
