Error while creating web dynpro project from DTR

Hello,
I am getting following error while creating Web Dynpro project from DTR,
org.eclipse.jdt.core.JavaModelException: File /<track name><DC><package>/.classpath is read-only.
Still project gets created but evenif I check out view , it does not allow me to edit it.
Also I have checked in and activated some changes but active copy in DTR is not reflecting those changes.
I tried Add subtree option in DTR perspective for folders in this project. Is it result of that?
Please help me in this regard.
Thank You
Beena

Hi Beena,
.classpath file should not checked in to DTR(uncheck the Read only properties). It is local file it contains class path for local system.
Generally in webdynpro project only src folder should be checked in DTR.

Run time error while running a webdynpro - urgent

Hi Guys
I am getting the following error while running the webdynpro.
My Default view is a INPUT_VIEW.
please see below runtime error
Regards,
Rahul
===========================================================
The following error text was processed in the system NSP : The lead selection has not been set. INPUT_VIEW
The error occurred on the application server BomwSAPk210_NSP_00 and in the work process 0 .
The termination type was: RABAX_STATE
The ABAP call stack was:
Method: RAISEELEMENT_NOT_FOUND of program CL_WDR_CONTEXT_NODE===========CP
Method: PATH_TABLE_GET_ELEMENT2 of program CL_WDR_CONTEXT_NODE===========CP
Method: GET_BOUND_ELEMENT of program CL_WDR_VIEW_ELEMENT_ADAPTER===CP

Hi Rahul,
The error appears when a UI element is bound to a context node or attribute on a node , where this node is defined as : cardinality 0..n or 0..1.
The framework will not create a default empty element in this case.
When the view is to be rendered, its source content doesnt exist. AS the node
has no elements. rendering fails.... Now in your case check for the cardinality. You can try with different cardinalities as per your requirements.
Check also the initialization lead selection property:
For cardinality: 0..n, selection: 0..1, initialization lead selection: false
and for cardinality: 1..n or 1..1, selection: 0..1, initialization lead selection: true
Best regards,
Suresh

Runtime Error While executing the WebDynpro Application

I am getting the Runtime Error While executing the WebDynpro Application. The error message is "TSV_TNEW_OCCURS_NO_ROLL_MEMORY".
It says like "
Short text
    No roll storage space of length 9728 available for OCCURS area.
What happened?
    Each transaction requires some main memory space to process
    application data. If the operating system cannot provide any more
    space, the transaction is terminated.
But while executing some other Web Dynpro Applications, i am not facing this problem.

Generally this error is a result of an infinite loop on internal table or select endselect statement where by severs temporary memory gets full. With no memory to insert new records in temporary memory system generates the dump.
Check your application or ask basis consultant to look at the memory parameters in instance profile.

Error on /SafeMode: error while trying to run project uncaught exception thrown by method called

i try run VS 2012 with /SafeMode. I create new empty Winform. When I start debug, I got:
"error while trying to run project uncaught exception thrown by method called through reflection"

Hi Matanya Zac，
Did you restart your machine? How about installing the VS2012 update 4?
>>error while trying to run project uncaught exception thrown by method
Did you install the VS update in your VS IDE? I met this issue before which was related to the VS update:

If still no help, I suggest you repair your VS, and then restart your machine, test the result.

VS 2010 error: 'Error while trying to run project: Not implemented'

I added a new Oracle database project using Oracle Tools for Visual Studio 2010. Once the Oracle database project is added to my Solution, my Visual Studio is no longer able to start the debugger and at times not able to run Test Cases. It error with 'Error while trying to run project: Not implemented'. If I unload the project, VS starts working fine.
Any idea on how to resolve this issue?

I ran into this problem as well, working in a VS2010 solution which included an ASP.NET web project and the v11.2.0.2.1 ODT version of the Oracle project.
Turns out that I was able to solve the problem by removing the Oracle project from the solution, and then adding it back in. From a SLN file point of view, it seems that as long as the Oracle SQL project is located after the Web Application Project that everything works fine.
Note that the SLN file is not organized by alphabetical project name, so changing the name of the SQL project doesn't help; its organized by order of project addition to the solution, so removing and re-adding is the way to go.

Classpath error while building the project.

Hi
I have created an application in which on clicking the button on one view , next view opens and data is displayed in the tables. This data i am giving as static, and for that i have created a java file. this java file is located in the subfolder i have created in the package path i have given. While building the application, i get these two errors :
1) The project was not built due to classpath errors (incomplete or involved in cycle).
2) Missing required source folder 'BPOutageTable/BPOT'
BPOutageTable is the application name, and BPOT is the subfolder in which java file is present.
This application is similar to "The Master/Detail Viewer Application" example in the tutorials.
Can anybody please help in this?
Thanks & regards,
Anupreet

Hi anupreet,
it error at buildtime means your code is not able to locate the folder and the java class.
if you switch to navigator menu and create java class in src/package node (in any package). You can get the class within the dynpro component / view.
Again try this, create a class say HelloClass in src/package node in some package. go to webdynpro view and try to access this class in dynpro code.

Hi,
You have give your classpath in your "lib" folder of the Dynpro application.
check your lib folder shows exact class path or not.
if you wish to add any jar files import it to your lib folder so you will not have compilation problem.
Hope it helps.If it is then close this thread.

Error while creating my first project on SP15 and why Help doesn't work?

Hello sdnrs,
I have a fresh SP15 installtion.
I have 2 problems creating my first webdynpro project.
1.When I go to file-new-project-webdynpro->(enter name)->next , I have windows poped up with the following error:
Plug in name: Web Dynpro Archive Builder
Plug in id: com.sap.ide.webdynpro.archivebuilder
class: com.sap.ide.webdynpro.archivebuilder.project.WebDynproStandaloneProjectWizard
Method: createJavaProject(IProject, IProgressMonitor)
Message: Problems encountered while setting project description.
Exeption: org.eclipse.core.runtime.CoreException: Problems encountered while setting project description.
I am frustrated cause I can't do any step futher...! Is there any special settings on the SDK, Window-Preferences, etc?
2.My Help doesn't work at all - it used to be (with SP11 slim) when i go - 'Help-SAP was docum-SAP webdynpro appl ' and I had my help window poped up.Now I dont have anything!
Thank you much in advance!
Bob

For your information there's another solution if you don't wanna reinstall your NDS or if the reinstallaion doesn't work.
The error is in the resources so you have to replace some plugin resources to correct the error. Because of that you need access to the resources from somewhere else.
1. Go to c:\Documents and Settings\"username"\Documents\SAP\workspace\.metadata\.plugins and replace org.eclipse.core.resources with a "working" resource
2. Go to C:\Program Files\SAP\JDT\eclipse\plugins and replace org.eclipse.core.resources.win32_2.1.0 and org.eclipse.core.resources_2.1.1 with a "working" resource.
Restart NDS and it ought to work

IO Error while deploying CAF WebDynpro DC

I am trying to deploy a CAF WebDynpro DC and get this error message while deploying with LocalDevelopment (no NWDI):
All required pre-development steps for local development of a WebDynpro with GP interface (used DC's, implemented interfaces, WebDynpro Library references) are successfully executed

Does anyone know what's going wrong and knows a solution?

Hi Andre,
There's no general deployment problem as I can deploy WD apps without GP interface successfully.
I got the apis for LocalDevelopment via the links in your SDN contribution 'How to get NW04s SP7 GP APIs for Local Development' from 9 June 2006.
I used and extracted the zips to the locations mentioned in the same SDN contribution.
I followed the procedure described in the SAP Library 'Creating Composite Applications' chapter 'Creating and Configuring the Web Dynpro Project' (URL = http://help.sap.com/saphelp_nw04s/helpdata/en/b2/06ae42848bb211e10000000a155106/frameset.htm) to create the DC dependencies and Library Reference.
After doing this, I'm able complete the example as described in tutorial 50 'Implement a Custom Web Dynpro Callable Object in GP* (URL = https://sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/e3f07a7a-0601-0010-ebbd-b9cfb445b814)
All goes well up until the deployment of the component.
I hope this helps you to help me again.
Thanx in advance.

Error while trying to archive project in iDVD

i've done a search on this and a few things have come up but there don't seem to be any solutions. i created a dvd. when i go to archive it, it works for a few minutes and then i get an error that says "alert: There was an error while saving the project."
a few notes:
i created the dvd today in idvd, so i'm positive that there are no missing pieces.
i have plenty of space on both drives.
i have tried saving the archive on my external drive (formatted correctly) and my hard drive and neither place works.
i have tried logging in as another user and that doesn't work.
i have tried archiving a few different projects including one i created just to test the archiving that has barely any video or photos.
does anyone have any thoughts? i have a very important dvd that i create each year and i would love to be able to have the pieces all together in case i ever need to burn a new one.
if there's a place on my mac where i can find more info about the error (that maybe someone here can understand!) let me know!
thanks!

What error code are you getting? Have you repaired disk permissions with Disk Utility? Also try this basic troubleshooting fix :
1 - delete the IDVD preference file, com.apple.iDVD.plist, that resides in your
User/Home/Library/ Preferences folder.
2 - delete IDVD'S cache file, Cache.db, that is located in your
User/Home/Library/Caches/com.apple.iDVD folder.
3 - launch IDVD and try again.
