Create BE Initiative, BE Feature and CPM Feature using Rally Rest Client in Java

We are trying to automate the project migration from one Rally workspace to other. Everything seems to work fine like we are able to migrate project and related releases/iterations/userstories/tasks from one workspace to another workspace.
But while trying to migrate BE Initiative/BE Feature/CPM Feature we are getting some exception related to Null Pointer exception but the error we are getting in Response doesn't seem to give much info.
A sample of code is -
String oldProjectObjectId = "12345";
String newProjectObjectId = "67890";
String oldRallyWorkspaceObjectId = "32145";
String newRallyWorkspaceObjectId = "67894";
QueryResponse beInitiativeResponse = queryRally("portfolioitem/beinitiative", "/project/"+this.oldProjectObjectId, "/workspace/"+this.oldRallyWorkspaceObjectId);
int beInitiativeCount = beInitiativeResponse.getTotalResultCount();
if(beInitiativeCount >0){
JsonArray initiativeArray = beInitiativeResponse.getResults();
for(int i=0; i< initiativeArray.size();i++){
JsonObject beInitiativeObject = initiativeArray.get(i).getAsJsonObject();
String oldBeInitiativeObjectId = beInitiativeObject.get("ObjectID").getAsString();
String oldBeInitiativeName = beInitiativeObject.get("_refObjectName").getAsString();
String owner = getObjectId(beInitiativeObject, "Owner");
JsonObject BeInitiativeCreateObject = getJsonObject(oldBeInitiativeName, "/project/"+this.newProjectObjectId, "/workspace/"+this.newRallyWorkspaceObjectId, owner);
CreateResponse beInitiativeCreateResponse = createInRally("portfolioitem/beinitiative", BeInitiativeCreateObject);
if(beInitiativeCreateResponse.wasSuccessful()){
String newBeInitiativeObjectId = beInitiativeCreateResponse.getObject().get("ObjectID").getAsString();
String mapKey = oldBeInitiativeObjectId;
String mapValue= newBeInitiativeObjectId;
this.beInitiativesHashMap.put(mapKey, mapValue);
}
else{
String[] errorList;
errorList = beInitiativeCreateResponse.getErrors();
for (int j = 0; j < errorList.length; j++) {
System.out.println(errorList[j]);
}
}
}
}
queryRally and createInRally functions use Rally rest client to fetch and create the required projects and associated attributes like releases, iterations etc.
After executing CreateResponse beInitiativeCreateResponse = createInRally("portfolioitem/beinitiative", BeInitiativeCreateObject); when it's trying to execute if(beInitiativeCreateResponse.wasSuccessful()) it is instead going to else block and thus printing the below mentioned error.
An unexpected error has occurred.We have recorded this error and will begin to investigate it. In the meantime, if you would like to speak with our Support Team, please reference the information below:java.lang.NullPointerException2017-12-05 11:01 AM PST America/Los_Angeles
But the important point that is when trying to migrate projects and it's related attributes like release/iterations etc. withing same Rally workspace the above piece of code works just fine.
Update1:
While analysing the issue I made the following observations -
The workspace in which I am trying to create the BeInitiative doesn't have BEinitiative, Be Feature, CPM Feature options in Portfolio items dropdown. Rather it has Theme, Initiative and Feature options in it.
Therefore, I think I was getting the previouly mentioned error. Now I made the following changes to the code.
CreateResponse beInitiativeCreateResponse = createInRally("portfolioitem/theme", themeCreateObject);
So now instead of creating the BEInitiative I am trying to create the theme only in new workspace but getting the following error -
Requested type name \"/portfolioitem/theme\" is unknown.
The object that i am passing to CreateResponse function is -
{"Name":"xyz","Project":"/project/1804","Workspace":"/workspace/139"}
Also code for createInRally function is as mentioned below -
public CreateResponse createInRally( String query, JsonObject object) throws IOException{
CreateRequest createRequest = new CreateRequest(query, object);
CreateResponse createResponse = restApi.create(createRequest);
return createResponse;
}

The Unknown Type error was occurring as a result of not passing the workspace's object id in which we were trying to create the portfolio item.
So after modifying the createInRally function to include the workspace object id we were able to create the initiative portfolio item.
The modified createInRally function is as shown below-
CreateRequest createRequest = new CreateRequest(query, object);
createRequest.addParam("workspace", "/workspace/1333333333");
CreateResponse createResponse = restApi.create(createRequest);
return createResponse;

So this is definitely an error in the web services api. You should never get 500 responses with an unhandled nullpointer. My initial guess is that when you're creating your new object some field on it is still referencing an object in the old workspace, and when we try to correctly hook up all the associations it fails to read one of those objects in the new workspace. Can you provide some more information about what your actual object you're sending to create looks like? Specifically what object relationships are you including (that may not be valid in the new workspace)?

View.getView() returns null

I'm trying to find my folder or view in my database. Which named Team Documents this folder has some filter option like By Date, By Category. But this returns me a null even the folder already exists.
String dbServer = "d23dbm95/23/A/IBM", dbFileName = "dbom\\farizan\\stsklb1.nsf";
public void runNotes()
{
Session session = null;
Database db = null;
View view = null;
Document doc = null;
try
{
NotesThread.sinitThread();
session = NotesFactory.createSession();
System.out.println("User = " + session.getUserName());
db = session.getDatabase(dbServer, dbFileName);
if(db.isOpen())
{
System.out.println("Title "+db.getTitle());
view = db.getView("Team Documents \\ By Date");
if(view == null)
{
System.out.println("still null");
}
}
}
catch(NotesException e)
{
e.printStackTrace();
}
}
I tried also to fill my getView() method like Team Documents. But still returns a null. Any approach to this problem?

While it would have been more helpful if you had included a link to a screenshot of your Domino Designer client's folder list, my best guess is that you have two folders, not one folder with "filter options". Also, my guess is that "Team Documents" is not actually a folder; it's just a prefix on the folder names that makes them appear to be nested in a parent folder.
If that's the case, you would need
iew = db.getView("Team Documents\\By Category");
Or
iew = db.getView("Team Documents\\By Date");
Note: No spaces before & after the backslashes.
If my assumptions above are not correct, then my suggestion would be to assign alias names to the folders in Domino Designer and use the aliases instead of the display names in your code. Frankly, that's always a good practice, because it allows your code to continue working even if you decide to change the display names.

Why would this cause a StringIndexOutOfBoundsException? Android

I am working on a small file manager to help me learn the basics of android, but I keep running into an error. WHenever I have a lot of items in the folder, it crashes and I get a message similar to this one,
java.lang.StringIndexOutOfBoundsException: length=26; regionStart=23; regionLength=-2
What could be causing this? The line it points to is line 2:
1.)String mimeType = "";
2.)mimeType = URLConnection.guessContentTypeFromName(f.getName());

You are missing some key lines we need to see, such as where f (a File? a URI?) is defined. However when I have seen this problem before it was caused by a URI with no Protocol set.
Making sure you have an extension and using MimeTypeMap#getMimeTypeFromExtension() is probably a good bet too

This error happens to me when the URL has a fragment, which can be identified by a # followed by some value. (For more on URL fragments, see https://www.w3.org/Addressing/URL/4_2_Fragments.html)
The URL fragment is not helpful in guessing content type, and since it is problematic in this case, it should be removed before calling URLConnection.guessContentTypeFromName().
Here is a simple function that returns a URL without the fragment:
private fun getSafeUrlForGuessing(url: String): String {
return try {
val uri = Uri.parse(url)
if (uri.scheme?.startsWith("http") == true) {
uri.buildUpon()
.fragment(null) // URLs with fragments cause URLConnection.guessContentTypeFromName() to throw
.build()
.toString()
} else {
url
}
} catch (error: Throwable) {
url
}
}

Setting repository location on SVNKit's SvnGetStatus

I need to get the current revision of a local working copy.
So far I've come up with this: (EDITED)
private static long resolve(File workingDirectory) throws SVNException {
SvnOperationFactory svnOpFactory = new SvnOperationFactory();
SvnGetStatus svnGetStatus = svnOpFactory.createGetStatus();
svnGetStatus.setSingleTarget(SvnTarget.fromFile(workingDirectory));
svnGetStatus.setDepth(SVNDepth.EMPTY);
SvnStatus status = svnGetStatus.run();
return status.getRevision();
}
I can't find a place to actually specify the location of my working copy, not even in the documentation.
How can I tell SvnGetStatus where to look for the working copy?

Try setting it as the target of the operation:
svnGetStatus.setSingleTarget(SvnTarget.fromFile(wcLocation))

Last modied by detail for a file using SVNkit

Hi how to get the last modified by value for a file using SVNkit.
Scenario : the file is updated from SVN and itr is available in local repo(working copy).

You could use svn keywords http://svnbook.red-bean.com/en/1.4/svn.advanced.props.special.keywords.html 'modified by' should be author.
You have to ensure, that the file with the keywords will be changed before every check in. This could be done with an ant script.
The keyword could be used in a constant with a second constant extracting the interesting part:
private static final String SVN_AUTHOR_BASE = "$Author: 113665 $";
/** Is filled in automatically on check in */
public static final String SVN_AUTHOR = SVN_AUTHOR_BASE.
substring(9,SVN_AUTHOR_BASE.indexOf('$', 9) - 1);

public static String getLastModifiedBy(File localPath) throws SVNException {
final SVNStatus status = SVNClientManager.newInstance().getStatusClient().doStatus(localPath, false);
return status != null ? status.getAuthor() : null;
}

SVNProperties props=new SVNProperties();
repository.getFile(filePath,new Long(-1),props,null);
String author=props.getSVNPropertyValue("svn:entry:last-author").toString();
is working fine.
