Using External jar causing Error

问题

I'm doing the following steps:

1. Create an empty Notes Database (Lotus Notes 9.0.1 on Domino 9 Server)
2. Creating Xpage with only one Label
3. Inserting external Jar File (Code - Jars)

I tested this setting with different jar Files. In most cases there are no problems but I found 2 jar Files which produce an error 500 in XPage without being referenced

starface-rpc-1.6.442.jar

log4j-1.2.17.jar

Does someone has an idea what can be the problem?

回答1:

Those two .jar files depend probably from other .jar files.

Look at the project pages like this for log4j to find out which .jar files you need to add to your application too.

Update:

Those .jar files stay in conflict with existing Java APIs used by Domino Server. That's why you get the error even without using them in an XPage as they get used by Domino Server executing an XPage.

Look here for explanation the log4j issue
