Reference External Java Libraries Across All SW Components/Namespaces

[Former Member]

Hi,

I went through "How to Perform SAP Data Lookups Within XI Mappings" By Jerome Delune

While I found it very useful, I could only manage the first three approaches. I could not test the Fourth approach(Reference External Java Libraries Across All SW Components/Namespaces).

https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/xi/how to perform sap data lookups within xi mappings

This is because I am using WebAS 6.40 and could not find the additional-Lib folder as mentioned. Please tell me the procedure how to reference External Java Libraries in WebAS 6.40.

Hi Dennis,

I would strongly recommend not to try this. Even if it works with your current version it is not officially supported and will probably not work with future releases of XI.

The philosophy of XI is, that no application coding should be deployed on the Integration Server. Instead this coding has to be uploaded as External Archives.

The guide you referred to is misleading in this point.

Hi Stephan,

I agree with yor view. But If I need to access the R/3 Backend for lookups, to better the performance I would prefer to cache some information like function templates. Besides the code for jco connection are similar in all cases. So I would ideally want to write it once and reuse it. Does XI has some features to help me do this?

Hi,

The best way to share java classes from imported archives across multiple software components is to use the "installation" dependency configuration in the SLD.

1. Create a "common" software component where all the common objects can be hosted, e.g. java classes in imported archives.

2. In SLD, create an Installation Dependency to the "common" software component in #1 in the software component where you wish to use java class from step #1.

3. Re-import your software component.

You should now see the java class from #1.
