The type AbstractStringBuilder is not visible

[Former Member]

Hi All,

I am currently working on the Tutorial "Exporting Table data to Excel 2003".

There is a method toExcel which uses StringBuffer class.The compiler is throwing this exception

"The type AbstractStringBuilder is not visible".

Is it because of the reason that NWDS is using JDK 1.4

Should I install JDK 1.5 to fix the bug.

Hai Nikhil,

If you added any public parts in your DC -- Used DCs with dependcy Deploy.

Deploy that DC also. otherwise uncheck the Deploy Dependency.

Hi Naga Raju,

Thanks for the inputs.

Can you please let me know how to do the stuff that you have mentioned "Deploy that DC also. otherwise uncheck the Deploy Dependency."

I did not create a DC rather I created a project with the name WD_ExcelExport. After that I unzipped the contents of WD_ExcelExport.zip in the WebDyn Pro project. Is this approach correct.

Please let me know.

Nikhil,

In component TableComp, goto Used Web Dynpro Components, check here if yu can see the ExcelExport Component, double click if it is there, check what is its LifeCycle, it should be CreateOnDemand.

Come to the component controller of TableComp, double click on it and check its properties, under Required Controller you should see ExcelExportComp and TableComp, if not click on ADD and take use of both of these.

rebuild application and deploy

Hi Nikhil,

StringBuilder is a class introduced with JDK 1.5. yeah error might be because JDK1.4. upgrade to 1.5

Hi Abhijeet,

I implemented a workaround for the problem by using the String class instead of StringBuffer.

However, when I am deploying the application then I am getting the foll. error

Failed to create delegate for component com.sap.tut.wd.tutwd_table.tablecomp.TableComp. (Hint: Is the corresponding DC deployed correctly? Does the DC contain the component?)

Let me know what am I missing.

Nikhil,

there are 2 components in that project, so is anybody of them giving some build errors, do you see any red mark in implementation of views or component controller,

Check out the component TableComp, i think this is not built properly, remove any error if it has, and Rebuild your project, and then Deploy

hope it helps

Hi Abhijeet,

There are no errors in the project. I am able to deploy the application and run it.

There seems to be some problem with the DC or usage of component. I am not aware of all these concepts.

Will have to search for it.
