Java Mapping - using Eclipse as IDE.

[Former Member]

Hello,

We need to write a complex java mapping. We are currently planning to use Eclipse IDE for developing the mapping class. (we dont have the NW studio unfortunaltey). The user defined function option in the IR will not suffice.

My question is - where do we get the com.sap.** libraries from - so that we can import those packages in our mapping code?

Thanks.

Hey dude,

you can use eclipse v3.2+ without any problems for Java mappings (NWDS is nothing else but eclipse 2.x + plugins). For Java Mappings you won't need any special functionalities (though for web services, modules etc, NWDS could turn out to be handy), just create a common java project and implement the proper interfaces.

You would need to get the libs for NWDS the same way, it doesn't come with additional embedded libs. For Java mappings, you'll need aii_map_api.jar lib, which can be found in your XI Box, just search for it in your instance folder.

For javadoc, go to https://help.sap.com/javadocs/NW04S/current/pi/index.html.

Regards,

Henrique.

since we dont have access to that XI server - is there any other place where we can download those jar files from?

Thanks.

Well,

there is a reason why you can't find it in help or sdn documentation. 😛

Maybe SAP doesn't want to let those who didn't buy its product to develop for it. Sounds reasoning, if you ask me.

Hi,

The necessary Jar files are downloaded & available in your PC when you use Integration Builder tools.

Normally Java webstart caches these files in your local directory.

You can find Java mapping related Jars in the following directory :

C:Documents and Settings%USER%Application DataSunJavaDeploymentjavawscachehttp%HOST%P50000DMrepDMrepository

Goto the directory, search for files like *aii_map_api.jar

It will give you list of Jar files like RMaii_map_api.jar , just rename it as aii_map_api.jar and use it in Eclipse or NWDS.

Note: While searching for Jar files take only Jar files with ~30KB size from the search results.
