Deploy a Spring/hibernate app on Netwaver Java

[DG]

Hi,

I have a Spring/hibernate application that I need to deploy on my Netwaver java server.

I have just deployeed the code and then I get the code and then I get the following errors.

I have created a local SC with a WAR DC containing the code. I have created an external libery for Struts and one for spring and the other files.

When I deploy the code I get the following error.

Should I only use on libery and is there something else I need to do before I can run the application. I'm using Netweaver 7.11.

Hi,

to use hibernate in NetWeavere Java, you must bundle and deploy the hibernate jars in a so called "heavy resource" enterprise application because hibernate needs different versions of classes from the NetWeaver core (especially apache classes) and must override these using "heavy classloading".

Maybe similar issue with spring.

See [http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/60642a88-95fe-2b10-d387-a245d48fc257]

Hi,

It seems quite close to solve the problem.

I still get the same error. Maybe I'm missing something to make it work.

Hi Daniel,

You can take a look at the following two articles:

[Running JPA Applications with Hibernate as a Third-Party Persistence Provider on SAP NetWeaver CE 7.1 EHP1|http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/50c5bd44-36c6-2c10-9283-9a26354c7aa9]

[Running Spring-Based Applications on SAP NetWeaver Composition Environment 7.1 and MS SQL Server 2005|http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/40eb2f24-9898-2c10-2396-9c9f35b637d9]

I hope they can help you with any uncertainties.

Hi,

I did not contenue on the path of trying the Spring app. I started from scratch I figured that it would be easier to create an app that works on more applications.
