Unable to access generator.dll file ?

Doug Groset — Mon, 15 Nov 2004 16:07:24 GMT

i have installed bridgeworks3.0A in openVMS 7.3and the development box has windows 2000 server,bridgeworks for windows 3.0A ,i've followed the instruction manual for installation.

when i try to run a sample program it says
"unable to access the generator.dll file?

can you also give sample code for creating a java client program (which i want to use as middle component)which will receive the request from WSDL and do some process and send the response back to the WSDL?

Doug,
In the 5 years that Bridgeworks has been available, not one person has reported this problem. However, in the last 2 weeks, 3 customers have reported it. (I wish I knew why...republican conspiracy maybe? :-)

I apologize about the inconvenience that this has caused, and I hope that this will help you get it resolved quickly.

"generator.dll" is a COM based sharable library that we install as part of the
BridgeWorks installation on Windows. It is used by the Bridgeworks GUI to
do the actual file generation.

At installation time it is copied into the BridgeWorks installation directory,
then registered within the Windows Registry. The error indicates that
something must have gone wrong with 1 of these steps during the installation.
(Note that BridgeWorks does support Windows XP.)

I would first verify that generator.dll is in the BridgeWorks installation directory,
and you have privledges to read it. (This could be an issue if you used a
different account on your PC to install BridgeWorks.)

I would then try to re-register generator.dll with the registry using the
RegSvr32 tool.

If this doesn't work, I would try removing BridgeWorks & reinstalling. Make
sure to go into the BridgeWorks installation directory after you uninstall to
make sure all of the files & directories have been removed...except for the
database file (.MDB).

Let me know how it goes.

Phil

Doug,
I forgot to address the WSDL (Web Services) sample request...
If you are just looking for a sample client that calls into one of our generated Java interfaces, you can find many examples on your PC below the BridgeWorks installation directory. There are Example & Tutorial directories that may contain something you can use.

However, this may not be needed for what you want to do.

In many cases, you can take the JavaBean interface/class that BridgeWorks generates and have the Web Services environment (such as AXIS) wrap and deploy it directly...with little or no code written on your part. The WS Environment/Toolkit can look at the Java interface/class (that BridgeWorks generated) & generate a WSDL definition for it. This WSDL definition can then be used to generate the java classes needed to serve up the BridgeWorks generated JavaBean as a callable Web Services. (Note: Sun's WS Dev Kit seems to be more automated than AXIS is.)

Bottomline: Don't do it yourself when a tool is available.
