Migrating project to Netweaver 7.3

Former Member — Wed, 23 May 2012 12:35:07 GMT

Hi,

we are migrating our Portal to 7.3 and I am migrating custom project from the ond one, thus I:

- exported a project from previous NWDS

- imported into NWDS 7.3

- right click on the imported project//Development Component / Convert to Development Component

I soved some problem with libraries and now the build gives only some warnings

I have tried to 'deploy but it fails and it gives me the errors here below

Does anyone knows what it is the cause ?

I missed some steps ?

Thank you,

Luigi

what is the source Portal version?? is this a Web dynpro app?

Probably you may not have fixed the APIs (lot of changes in APIs in 7.3) and adjust the Web Dynpro app to the new run time..did you use the migration wizard to make it compatible to 7.3..

See this link for a detailed step by step on how to perform the migration

Hi Sandip,

sorry for some precious info forgotten and thank you for the quick reply.

The old Portal rel. is 7.0 and the new one is 7.3

Yes, they are Web Dynpro apps!

We have not a CE environment thus custom projects were developed with NWDS 7.0.15.

This is why I installed the NWDS 7.3 to migrate apps.

I saw several posts but it seems to me they refer to issues in NWDI environments.

did you find any error in the problem view of nwds?

Re: Migrating project to Netweaver 7.3

Former Member — Thu, 24 May 2012 08:41:52 GMT

Yes, but they are just "Warnings" (107) and "Infos" (3).

Here is an example of warning

Description	Resource	Path	Location	Type
ArrayList is a raw type. References to generic type ArrayList<E> should be parameterized	TableSorter.java	/LocalDevelopment~fatture~demo.sap.com/src/packages/constep	line 148	Java Problem

Re: Migrating project to Netweaver 7.3

SandipAgarwalla — Thu, 24 May 2012 09:26:08 GMT

Check the code at line 148 of tableSorter class. Can you paste the code here for us to check and also the lines of code above it (max 2)

Re: Migrating project to Netweaver 7.3

Former Member — Thu, 24 May 2012 10:31:06 GMT

Here is the lines (last one is 148).

Consider that they are just warnings and the deploy stops because ov the above errors...

************************************************************************************************************

if (bindingOfPrimaryProperty == null || !bindingOfPrimaryProperty.startsWith(dataSourcePrefix)){

//no attribute found or outside of data source

column.setSortState(WDTableColumnSortDirection.NOT_SORTABLE);

continue;

}

String attributeName = bindingOfPrimaryProperty.substring(dataSourcePrefix.length());

Collection subnodes = new ArrayList();

aah, i forgot its just warning..Looks some issue with your NDS plugins..

What is the version?

Re: Migrating project to Netweaver 7.3

Former Member — Thu, 24 May 2012 16:07:26 GMT

Here is the NDS version:

SAP NetWeaver Developer Studio

SAP NetWeaver 7.3 SP07 PAT0000

The error (java.lang.reflect.InvocationTargetException) is not helpful ?

Hi Luigi,

Looks like this issue is because of the supporting library files which you add while creating DC on NWDI. Previously you must have added JTechs 7.0, JEE 7.0 and JBuildt 7.0 SCAs and you are trying to deploy this in NWDS 7.3 environment where java run time is 1.6. So, there are lots of incompatabilities.

Hi,

I tried reinstalling the whole environment, that is:

- del NWDS 7.3

- del all JRE's/JDK's

- installed only JDK 1.6 (under Programs\Java I have \jdk1.6.0_26 and \jre6)

- installed NWDS 7.3

- imported the zip project from NWDS 7.0.15

- Repaired and Sync

Unfortunately, after have been fixed a couple of library problems, the \DC\Build reports the same errors mentioned before (here below copied).

At the moment, I got only WARNINGS of type "deprecated":

could they justify the build error and the fact that it cannot proceed ?

how the lines in the build log and in the error log view should be 'read' to find the problem ?

Thank you,

Luigi

All,

after have been repeating the steps to migrate project from 7.0 to 7.3, I found that the main issue was in the language choosen when importing the project.

I had to set the local language instead of the default American English and, after some other minor problems with java library dependencies, I managed to build and deploy.

Thank you,

Luigi

Hi luigi ,

What was the language that you chose? Did you migrate local webdynpro project from 7.0 to 7.3 version. I am facing exactly same issue as yours.

Hi Navya,

I was importing projects from nwds/portal 7.0 to nwds/portal 7.3 (version details in the above history).

I solved choosing 'Italian" , the original language of the projects.

I think you should check the original language of yours.

Re: Migrating project to Netweaver 7.3

Former Member — Tue, 31 Jul 2012 07:48:25 GMT

Hi Luigi ,

I my case the original language is english itself.

I am trying to migrate the local dynpro project from 7.0 to 7.3 version by importing local project in nwds 7.3.

As local projects are not supported in 7.3 i converted it into DC and at that point of time its asks for lanuguage which is set as american english as the default language in my case is english itself. I used the repair option and tried to fix the issues with libraraies.

In problem view it doesnt show any error but when i build it it shows same remoteinvocationexception in error log.

Currently it gives me same error when i try to build and deploy

Regards

Navya.

I found that the errors like java.lang.reflect.InvocationTargetException are not so exclusive and did not help much on troubleshooting.

I can tell you that many problem I solved in the migration were due to:

- language (as above)

- java build path to be filled like the old nwds project

- need of a DC library to be added as "Dependencies" of the project ( I think you did it )

In one case, I was not able to build while the same project was built on a pc of a consultant with the same configuration of nwds/java and the same libraries.

The troubleshooting with java is really a problem itself

Luigi

Hi Luigi ,

I was able to import the local dynpro project and deploy it but now theres one more issue.

In my local dynpro project i had used models for backend connectivity (rfc) but now after migration i am not able to see those models . In your case had you used models and were they migrated?

Regards ,

Navya.
