I have developed a Web Dynpro Java Application & the requirement is it should run in background daily in Sap Portal 7.31

For this We have developed a Web dynpro java 7.3 application & created a EJB project for scehduliong job in portal.

Application is working properly & EJB project is working properly,but  when we add Web dynpro java application in EJB project & scehdule in portal .it si giving an error.

Once the Application runs on schedule it is giving an "Error" as the Status

  This is the code in EJB ,but it is not working...]

public void onJob(JobContext jobContext) throws Exception

{

InitialContext ctx = new InitialContext();

String lookupString = "company.com~grpassign.ear";

Object obj = ctx.lookup(lookupString);

TestComp ejbHome = (TestComp)javax.rmi.PortableRemoteObject.narrow(obj,TestComp.class);

Grpassign ejbHome = (Grpassign)javax.rmi.PortableRemoteObject.narrow(obj,Grpassign.class);

ejbHome.wdDoInit();

}

Hello,

we have Netweaver 7.0 and we are checking the 7.3.

I'm can not see the Context tab in the view that i created.

Is something missing in the installation?

Thanks

How to highlight an input field at runtime ??

I just installed NW73; ran initial configuration successfully.  Migrated a WDJ application to 7.3 that was developed in 7.0; also migrated Models to use ARFC3 model.  Deployed WDJ application successfully to NW73 server.  I've created RFC JCO destinations (TK_RFC_METADATA_DEST & TK_MODELDATA_DESK) using NWA-->Configuration-->Infrastructure-->Destination.

When I ran the application, getting the following error:  [any help resolving this issue is appreciated]

Hi Experts,

I am using UME api to fetch user details from portal.My scenario is i am fetching set of users from backend and need to get the user details from portal using UME api.

am using below code to fetch the user details.

IUser user = UMFactory.getUserFactory().getUserByUniqueName(signum);

but am getting below exceptions.

UMException:User found, but unique name "xxxxx" is not unique!Caused by: null1490

UMException: User "xxxxx" does not exist.Caused by: null1487.

I know that below exceptions are occuring because either user is not unique or user is not avilable in portal.But i dont want exception to be triggered in such case.Instead is there any method to which i can pass users from backend and check if user exist or not and then fetch user details and also if user is not unique also i want to display the user details.

Please help me out with this.

Thanks

Hello,

We are planning to implement SAP Gateway version 7.4 and we have choosen Central Hub System as an option. Grateful if someone could clarify on the below points;

1. Which is the best development platform for UI which will consume Gateway Service. These developments will be deployed on J2EE Engine (on EP) and this development will be used of desktop purpose.

2. How to connect J2EE Engine (EP) with SAP Gateway System? We are looking at something similar to JCo/WS Destinations. Our understanding is that credentials has to be maintained in the development (code) as a clear text to establish the connection to Gateway server. This could be a security issue.

We are using SAP EP version 7.30 SPS5 from quite a long time and choosen Java Web Dynpro as a UI technology in which we consume Web Service (from PI) via Web Service Destinations.

Thank in advance.

Regards,

Anil Patil

Hi

We are using SAP Portal 7.02 SP12 version. In User Admin role using the Export button we can get the user/role/grouop details and we can save the file in the desktop .If we want to add new users to the Group then we just need to add the user id in the saved text file. Then we can import the file to the portal using the Import tab of User Admin role. 

The above task needs to be done by portal administrator.

Can you please provide the information if its feasible to automate the above procedure by developing any application? That is at scheduled time application will run automatically. This application will read the user id, portal group and language information from a file and assign the user to group and update the logon language of user in portal data base.

Thanks & Regards,

Susmita

■  JDO applications

Applications using Java Data Objects (JDO) need special attention. Though the applications themselves can be compiled and built with JDK 6, the actual JDO classes need to be compiled with JDK 1.5 or with JDK 6 using the “-target 1.5” option. JDO classes can be easily detected by their accompanying .jdo and .map files.

The requirement to use JDK 1.5-compliant build target results from the fact that the class files of JDO classes need to be post-processed by a tool known as the JDO enhancer. The class file format was significantly changed with JDK 6. However, the JDO enhancer does only support the JDK 1.5 class file format. Therefore, JDO classes must be compiled in such a way that the JDK 1.5 format is used for the class files. This can be achieved by using JDK 1.5 directly or JDK 6 with the option “-target 1.5” in the build.

Can anyboy help me?

Thanks in advance.

Hi,

The first row in the table getting selected by default in wd java.

I want to have no row selected by default.

Kindly help.

Hi folks,

I need to display such a structure in my table.

Column1                             Column2

Image1 + Text1                    Text12         

|_

     Image2 + Text2               Text22

     |_

          Image3 + Text 3         Text 32

I created a table with a TreeByNestingTableColumn(for column1) and one regular column(for column2).

The problem, that I am facing here is, I can display either Image or Text under Column1, but not both.

I need to display them together with the node icon(which will come from TreeByNestingTableColumn).

Thus, the triangular icon(node icon), image and text should be displayed in the same column.

How can we achieve this?

Thanks,

Swapnil.

Hi Friends,

Till now I have been working on simple or plain WebDynpro Components.

Hi,

Customization required on ESS Leave request iview & MSS Leave request Approval Iview.

SAP NetWeaver 7.3

Requirement:

For employee:

While employee is applying for Leave request under Leave request iview of ESS, he should have the functionality to upload the certificate (medical certificate, tickets etc) in .jpg or .png etc.
