Re: Using existing jars in NSF

Have you tried to add the JARs directly to application's classpath? See Java Perspective and Configure build path?

how have you added these JARs to your application?

As far as I know from Java Domino Agent world, there every JAR were loaded on each request. Not sure how they (JARs) act as XPages resources.

Yes I did.

I put my jars to the WebContent\lib Folder. And then include the jars in Properties/JavaBuildPath/Libraries then Add jars.

This solution works for me, but it's to slow because the jars are loaded every time I call the XPage.

Hi,

what if you add the jars to the jvm\lib\ext folder of the domino server?

It's unfortunate that this behaves like this...

Have you tried some other WebService clients? AXIS is OK but not the best one. Which one is the best? Don't know but XFire is quite good and fast (http://xfire.codehaus.org/)

Then there's always the possibility that you just code the WebService request using Java (java.net package classes). Here's one (old) article that I once used.

http://www.collaborationseminar.com/eview/volr6.nsf/0/1AF49D3658E834C78525723A006E7D08/$File/003-024%20Calhoun_NovDec06_Web.pdf

See the code part where they create the Soap client.

I know... a lot of code which should be handled by a framework but .... atleast one more option to try.

@Sven

jvm\lib\ext folder is to use this jars in agent java only isn't ?

@Rami Muurimaki

the easiest way would be, that i can use axis classes which allready within the domino
but the Service class have no public constructors

the strange thing for me is ... i put the same webservice call two times on a XPage
and i measure the time which the first call consumes and then the second

the second call is much faster but the same call (and i can measure the time which the webservice offering system consumes, it's the same)

so for me it's seems like the jars are loaded with every call of the xpage

No. Jars in this folder are usable by XPages.

I agree on the JAR loading.

I've struggled with this problem many times. In heavy trafic Domino get exthausted by the JAR loading (= memory usage). Event recycling didn't help if I remember correctly.

@Sven

i tested the javm/ext/lib folder i think your right ... this is the right place for my jars

but i get in trouble with some other libraries which already contains classes which I need but not all :P

in my case it's the common-logging.jar
