Please help with first Adapter Module Bean NWDS deployment

[Former Member]

Hello experts,

I am following instructions to deploy a first Java Adapter Module Bean to our development system and getting a problem. I really appreciate any help in this case.

I am following these instructions:

http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/c0b39e65-981e-2b10-1c9c-fc3f8e674...

I have copied the library files and referenced them as mentioned in the document, but maybe these differ based on PI version? We are on 7.11.

I'm trying to load this source code:

In NWDS when I deploy it has a warning:

1. File:E:\Data\NWDS-workspace\ReplaceString-ear\ReplaceString-ear.ear

So I had multiple issues holding me back, but glad to say I have the Module Adapter deployed now and it is working as it should in development.

I wonder what is your experience for source control with these adapter modules. Is it possible to transport them like mapping or config objects? Or maybe we define landscape of QA and Production in NWDS and "run" the ejb project to each platform when it is ready? Looking for practical advice here.

Thank you!

Hi Aaron

Glad to hear that your issues have been resolved.

For the sake of completeness and also future reference for others, can you share what actually you did to resolve them?

Was it the module code, the JDK, the NWDS version, the module sequence, etc, all of the above?

Regarding the source control and transport, the SAP recommended way would be to have NWDI. In reality though not every organization will have NWDI, so it's a manual deployment into each landscape - either through NWDS directly, or packaged into an SDA for Basis consultant to deploy.

Hi Aaron,

For module transport, you can use CTS+ for this. There is an option there to attach an ejb, once it gets imported, the module is automatically deployed on the target system.

Mark

Thanks Mark, we are using CTS+. How do we export a module ejb object to transport proposal?

Good point Eng,

For maybe helping someone else, so far my issues were:

1) NWDS deployment was failing because the hostname of server system seemed to be case sensitive.

2) I placed Java Bean code in wrong place of NWDS project, so deployment could not find necessary module implementation

3) I was worried about warnings of the referenced libraries but these could be ignored.

4) I configured Adapter Modules in wrong order

5) Module Code or Parameters

• Getting null error at runtime, had to remove single quotes from separator
• Getting null error at runtime because module code (or perhaps Java version) not detecting empty string (e.g. want to replace string with empty string
• Java replaceAll method was not working with string arrays, had to convert to actual strings (again maybe this is down to a java version)

6) Wondering best practice to deploy module to different platforms

[markangelo_dihiansan · Accepted solution]

Hi Aaron,

You won't be able to attach it on that page. You need to go to the cts admin page (where you release or modify your transport) and there is an option there to attach the ejb.

In the screenshot, there should be an attach option, but since I am not an admin I don't have it.

As far as I know, there are two URLs for cts +, the first one is when you click modify/create request and the second is the admin URL.

Ok I see it. I have the option to upload a file from client or server and apply it to an application as in the screen shot. What file would I attach from the NWDS project? Would it get deployed correctly to the other servers in the transport workflow?

[markangelo_dihiansan · Accepted solution]

Hi Aaron,

The file type should be J2EE and your file should be in .ear format. It would get correctly deployed

in the server once you import it in stms.

Mark

Change position of modules

this is a nice url:

Thanks Juan, I noticed that mistake also 🙂

[Former Member]

Ok, I could see that I had my ReplaceString bean code in the wrong part of the project. After resolving that, I am seeing some warnings about the project. The first 5 are about the PI_AF_LIBS jars. These files are all existing in the path on my PC, downloaded from PI in c:\PIJars\UserModuleLib

Can someone help me understand these warnings and how to correct? Many thanks!

[Ryan-Crosby]

Hi Aaron,

None of those warnings listed in Eclipse should stop you from building the archive and deploying it to your system.  The first five just indicate that the libraries you are referencing will not be packaged in the build and deployed to the system which is fine because they will already exist.  The others about the archive and the MANIFEST stretch too far to see the full text but the others can be ignored and will not cause any issues at runtime.

Hi Aaron

I've noticed from the screenshot that you are using JDK 1.6 for your NWDS. If you have a look at the following Wiki, it says that PI 7.1x is running on JVM 5.1.

Troubleshooting PI ESR and Integration Builder Logon Issues - Process Integration - SCN Wiki

Therefore you need a JDK 1.5 for your NWDS. Also, can you confirm which version and SP of NWDS are you using? For PI 7.11, you need NWDS CE 7.11 and not anything higher.

Aaron,

FYI. replacing string can also be achieved using Java mapping. If you are not using FCC or other modules after replacing string, I would suggest using Java Mapping.

replaceAll("ns0:something","ns0_somthing").replaceAll("foobar","_");

Link1, Link2.

[Former Member]

Thanks Raghu, I thought this could be nice to configure at will for reusability. I think in mapping for each new use case we need to redeploy if it were to change slightly? However, I may still try it. Thanks for posting that video!

Hi,

Did you implement Module interface in your bean implementation class?

Looks like your code has some problem, share your bean implementation class code.

Thanks,

Anand

Good call Anand, I looked back at the bean class code and found an error. I will come back soon
