Apache Reverese Proxy Issue

[MohamedAwny]

Dear Experts,

We are having a requirement to publish BI Reports and Dashboards outside the DMZ.

We have followed the following URL for the setup (excluding the Load Balancer part):

https://wiki.scn.sap.com/wiki/display/BOBJ/Configuring+the+reverse+proxy

Now, we are getting the Login Page of the one on the OpenDocument Links configured to be accessed through the reverse proxy.

But after providing the user credentials, we are getting the following error:

HTTP Status 500 - org.apache.jasper.JasperException: java.lang.NullPointerException: while trying to invoke the method com.businessobjects.swd.appcontext.CafAppWebSessionContext.getPreferredViewingLocale() of a null object returned from com.businessobjects.swd.appcontext.RequestInfo.getCafAppWebSessionContext()

Appreciate your valuable assistant on that.

Best Regards,

Hello Mohamed,

According to that tutorial there are other steps to follow before configuring the reverse proxy :

1 - Installing Apache 2.4 as a service.

2 - Enabling the proxy cache.

3 - Securing the Apache web server.

4 - Configuring the reverse proxy.

Please verify that you have followed all of the steps mentioned above.

Best regards.

Dear Kashif,

We just revised the configuration against the procedure that Bayrem described and we found that there was a configuration mistake in the httpd.conf. We followed the Wiki page for the reverse proxy setup
