Referencing JCO from a J2EE Web module

[Former Member]

Hello,

I need to run a J2EE application on the SAP Web AS. WAS version is 6.40 PatchLevel 100627.313.

In Netweaver Developer Studio, I created a web module project for my web application and an enterprise application project to which I added my web module.

In the application-j2ee-engine.xml file, I defined a reference to the jco library:

<reference reference-type="hard">

<reference-target provider-name="sap.com" target-type="library">com.sap.mw.jco</reference-target>

</reference>

When I lanched my application, I get the following error:

500 Internal Server Error

SAP J2EE Engine/6.40

Application error occurred during request processing.

Details: com.sap.engine.frame.core.load.SAPNoClassDefFoundError: com/sap/mw/jco/JCO

Exception id: [000F1F673662003F000005120000139C0004195804E71341]

I think I did everything I should in order to get it to work. Any idea?

Thanks,

Laurent

In your <b>Web Componenet</b> Project, Please add <b>sapjco.jar</b> as an External jar.

<b>Rebuild</b> the WAR and EAR and <b>deploy</b> it !!

Thanks

Hi Laurent,

Add the JAR file in the web module as an external jar.

Create a WAR file and add the webmodule to the EAP.

It works in my case.

You mean sapjco.jar?

Normally it should be installed on the WAS, that's the goal of the reference statement...

Hm, Laurent, the only thing I can suggest is to restart the server. Also, make sure that your ear and war doesn`t contain any jco*.jar`s.

Hi Laurent,

See this thread same error but resolved: did you added sapjco.jar to the library

I did what has been described in the first answer (reference in the xml). Is there anything else to do?
