modifing mast head

[Former Member]

We have a requirement where we need to change the images for the mast head. So I downloaded com.sap.portal.navigation.masthead.par and modified the HeaderiView.jsp. I didn't change much, I just appended "Hello" to firstName and deployed and keep get following error:

Exception ID:04:22_05/04/06_0002_5925350

It looks like there is a dependent classes that I need to deploy along with this par file.

Which par file should I be modifying?

Any suggestions would be greatly appreciated.

Thanks,

Praveen

Hi Praveen,

You need to include the com.sap.portal.navigation.mastheadapi.jar into dist\PORTAL-INF\exlib\of your project.

and

com.sap.portal.navigation.mastheadcore.jar into

dist\PORTAL-INF\private\exlib\

You can get the jar by unzipping the original par file.

Cheers

Guys:

Thanks for your quick response. Defiantly very helpful answers

I basically downloaded a corrupted par file and I was getting all these error message. I downloaded par file from a different server and it seems to work great.

I don't know how to reward points to all of you.

Once again guys, thanks for your answers.

Thanks,

Praveen.

Hi Praveen,

You have to add com.sap.portal.navigation.masthead_core.jar file in your classpath.

you put this jar file under dist/PORTAL-INF/lib/

Now upload the par file from your NWDS.

It should wok fine now.

If you need more help on this let me know.

Karthick Eswaran

P.S:Award points in sdn for helpful answers.

Hi Praveen,

If you've used the .par.bak, they are inside, but are not integrated if you've created a new portal component from PAR through NWDS (it's a NWDS bug). So open the original PAR (it's a ZIP) and manually put the JARs into the lib or private/lib directory, correspondingly.

Pooja.
