Migrating from an existing Java Web Application to Portal

[#1]

Hi,

How feasible is it to migrate from an existing Java application to SAP Enterprise Portal ? What are the factors that needs to be considered ?

It is quite a huge web application which connects to an existing SAP HR System. The functionalities and business processes are different from what we have in ESS & MSS and it calls a lot more transactions which are not standard SAP Transactions. So just importing the business package is also not going to serve the purpose. Customizing the business package to meet their requirements is going to be highly time consuming.

Recreating the application in Webdynpro or HTMLB is again a killer task.

How do I go about this ? Is there a way that I use their existing web application as it is to have it running on Enterprise Portal ?

Any document which precisely explains the procedure to do this ?

Any valuable inputs would be highly appreciated and awarded.

Thanks in advance.

Hi Sunil,

what do you mean with "an existing Java application"? Is it a desktop application using AWT/Swing/SWT for example or is it already a web-based application built on top of Servlets and JSP?

Converting a desktop (standalone) application into a web-based application is quite difficult, as you have to recreate the complete user interface and adopt most of your business logic to run inside an application server. If your business logic is already running inside an application server, you would just have to adopt your user interface.

If your java application is already a web-based one, you would have to adopt it to the Poral environment. Should be possible to reuse much of the components (especially the user interface).

But you do have to get comfortable with the portal environment in either case. Unfortunately, there are no guides, that could assist you in this migration.

Kind regards, Lars

Hi,

If am not wrong, you want to migrate a non-SAP Java application to SAP application server?

Check these links:

Hope it helps.

SAP Enterprise Portal actually runs on a J2EE Engine on SAP Web Application Server. So, practically you can deploy any J2EE application on it. But when you say SAP Portal it means using Portal Framework for which you will have to convert existing application to use Portal framework. I am not aware of any simple procedure for it.

But my question is if you are not going to use Portal framework then why do you want to use SAP Portal ? Any specific reasons ?
