.NET Connector DLL Deployment Problem

[Former Member]

Hi Everybody,

I implemented a Component (registered COM DLL) which retrieves some Information with the SAP.NET-Connector in C#.

My Dll does several other things too and it must be called by an ASP-Page. Everthing works fine, except the SAP-Connector. I got the following Errors:

AddTableInfoFromSAP: new SAPTable: ERRORSystem.ApplicationException: GetTableFromSAP: new SAPProxy1System.IO.FileNotFoundException: File or assembly name w3jcq-zf.dll, or one of its dependencies, was not found.

File name: "w3jcq-zf.dll"

I found several Newsgroup postings about similar problems. I tried additionally to register both, the Connector and my DLL in the GAC, wich does not help.

thanks in advance for any help...

Sometimes this kind of problems has to do with unsufficient access rights on them temp directories.

That was quick

I also checked this.

Also to prevent Problems of that Type, I currently use an local Administrator as Guest Account within IIS.

Some more hints: The issue is not specific to .NET Connector, but related to Microsoft's XMLSerializer. So you can e.g. search Google for

"System.IO.FileNotFoundException: File or assembly name" XmlSerializer

I solved it.

Thank's to your comment I double checked the Security Settings on C.\winnt\temp.

I set Read/execute Rights for IWAM_*. AND (that's the Step I didn't do before) i restarted the IIS - it works.
