[SOLVED] Problems with Report Caster API after migration from 7.1.x to 7.6.11

Hi Guys,

We recently migrated our servers from WF 7.1.4 to 7.6.11. However after migrations, our front end application using report caster API stopped working. application logger showed, it hung on connecting to report caster server.

I know there has been a change of report caster libraries from 7.1.x version, so I included the new libraries (all the 3) and re-compiled the application. After re-compilation, it no-longer hangs connection but throws the error unable to connect to distribution server, make sure its running.
The application is using CasterManagedConnectionFactory() and I've compared the documentation, there has been no change in the function definition or usage coming from 7.1.x

I checked RC configuration and ports and they are fine because when I do
telnet RCHOST RCPORT
I get the standard ¼φ so that means RC config is OK

Any ideas what might be causing the app not to connect, especially since its running fine on 714?

Can you log into ReportCaster outside of the API calls?

In 714, if ReportCaster couldn't connect to the database it wouldn't start at all.

In 7611, it will start in "Console Only Mode". As a result there will be a listener, but it won't fully be running.

If I remember correctly the API error codes for the distribution server being in console only mode are not very descriptive, and simply make it sound like the distribution server is down.

Assuming that ReportCaster is working properly outside of the API calls, I'd start by getting ReportCaster Servlet and Distribution Server traces and see if there is anything useful within them.

^Thanks for the reply..
Well yes, I certainly can login reportcaster from Dashboard link.

I looked at ReportCaster logs and server traces found nothing useful there. There is some activity in console trace, but I couldn't relate it to any use.

However my local tomcat (on which the application is deployed) shows this error in tomcat window.

Unable to establish connection to ReportCaster repository. Contact your ReportCaster Administrator. WebFocus Server EDAUNIX Initialization Error (java.lang.ClassNotFoundException: ibi.jlink.EdaDriver)

I worked with RC admin, but he couldn't find any problems on server. Could it be the whats causing all this and where do it start fixing it?

That looks like its missing the jlink.jar file in the classpath. Can you add:

\ibi\WebFOCUS76\webapps\webfocus76\WEB-INF\lib\jlink.jar

To the classpath of your API program?

This Jar FILE will be missing in your classpath, or the classpath ref for this JAR file will be wrong or missing.

Or might be, the properties has to be changed somewhere in server configurations.
