Custom Database Servlet: access to Domino Backend Classes?
By Wolfgang Herder 1 decade ago

Hi,

the possibility of having servlets' code reside in databases instead of jars on the server's filesystem is very interesting. The examples that I see all redirect to other REST service implementation that come with the extension library. As a first step of getting my existing servlets to work, I tried to create a Notes Session object. So far, I have failed. Did I miss something or is that not supposed to work?

What I have tried so far:

NotesFactory.createSession() returns null.

ExtLibUtil.getCurrentSession() results in
NotesException: Cannot create a session from an agent
at lotus.domino.local.Session.checkSecurityManagerExtender(Unknown Source)

DominoUtils.getCurrentSession() throws a NullPointerException at com.ibm.xsp.util.FacesUtil.resolveRequestMapVariable(FacesUtil.java:1050)

ContextInfo.getUserSession() throws java.lang.NoClassDefFoundError: com/ibm/designer/domino/napi/NotesAPIException
The servlet code has access to that class (I require com.ibm.domino.osgi.core and com.ibm.domino.napi plugins in plugin.xml), I can create instances of it.

Thanks for any help!

Cheers,
Wolfgang Herder

Can you please attach some sample code failing?

We can then have a look and tell you what the best approach is. Also, are you using 852 or 853?

This is on 853.

Attached just the java code for the test class here, will create another response with minimum test case database.

The result on my server for the query

http://xxx/ExtLibTest.nsf/xsp/testagi/echo?bla=blub

is

Hello unknown, you asked: bla=blub

The server console reads:
