Custom renameParticpant dialogue with "FATALERROR: No input element provided"

I am creating a custom renameParticpant to rename an Eclipse project's launch configuration files, and to change the APPNAME variable in the Makefile. The Makefile side works 100% of the time, but attempting to rename the launch configs causes the following error to occur:
<FATALERROR
FATALERROR: No input element provided
Context: <Unspecified context>
code: none
Data: null
>
This error occurs when the changes are being validated at the following line in org.eclipse.ltk.core.refactoring.PerformChangeOperation [line: 248].
fValidationStatus= fChange.isValid(new SubProgressMonitor(monitor, 1));
Below is a screenshot of the variable view. I suspect that my compositeChange is not in the correct format or is missing some information, however; the error dialogue and logs don't give any helpful information.
Debugger variable view of fChanges
The following is relevant code snippets:
// This one sparks joy (it works great, 100% success)
final HashMap<IFile, TextFileChange> textChanges = new HashMap<IFile, TextFileChange>();
// Stuff gets put inside
textChanges.put(makefile, changeAppname);
// This one does not spark joy (it runs, but results in an invalid Change)
final HashMap<IFile, RenameResourceChange> renameChanges = new HashMap<IFile, RenameResourceChange>();
// Stuff gets put inside
RenameResourceChange renameChange = new RenameResourceChange(
launch.getFile().getProjectRelativePath(), newLaunchName);
renameChanges.put(launch.getFile(), renameChange);
// This is where they get added to the hashmap.
CompositeChange result;
if (textChanges.isEmpty() && renameChanges.isEmpty()) {
result = null;
} else {
result = new CompositeChange(
String.format("Rename project references and dependencies for %1$s", proj.getName()));
for (Iterator<TextFileChange> iter = textChanges.values().iterator(); iter.hasNext();) {
result.add(iter.next());
}
for (Iterator<RenameResourceChange> iter = renameChanges.values().iterator(); iter.hasNext();) {
result.add(iter.next());
}
}
return result;
I looked into adding or generating a changeDescriptor, however that seems like the wrong approach.

How to fix "GetStatus Write RFID_API_UNKNOWN_ERROR data(x)- Field can Only Take Word values" Android RFID 8500 Zebra

I am trying to develop and application to read and write to RF tags. Reading is flawless, but I'm having issues with writing. Specifically the error "GetStatus Write RFID_API_UNKNOWN_ERROR data(x)- Field can Only Take Word values"
I have tried reverse-engineering the Zebra RFID API Mobile by obtaining the .apk and decoding it, but the code is obfuscated and I am not able to decypher why that application's Write works and mine doesn't.
I see the error in the https://www.ptsmobile.com/rfd8500/rfd8500-rfid-developer-guide.pdf at page 185, but I have no idea what's causing it.
I've tried forcefully changing the writeData to Hex, before I realized that the API does that on its own, I've tried changing the Length of the writeData as well, but it just gets a null value. I'm so lost.
public boolean WriteTag(String sourceEPC, long Password, MEMORY_BANK memory_bank, String targetData, int offset) {
Log.d(TAG, "WriteTag " + targetData);
try {
TagData tagData = null;
String tagId = sourceEPC;
TagAccess tagAccess = new TagAccess();
tagAccess.getClass();
TagAccess.WriteAccessParams writeAccessParams = tagAccess.new WriteAccessParams();
String writeData = targetData; //write data in string
writeAccessParams.setAccessPassword(Password);
writeAccessParams.setMemoryBank(MEMORY_BANK.MEMORY_BANK_USER);
writeAccessParams.setOffset(offset); // start writing from word offset 0
writeAccessParams.setWriteData(writeData);
// set retries in case of partial write happens
writeAccessParams.setWriteRetries(3);
// data length in words
System.out.println("length: " + writeData.length()/4);
System.out.println("length: " + writeData.length());
writeAccessParams.setWriteDataLength(writeData.length()/4);
// 5th parameter bPrefilter flag is true which means API will apply pre filter internally
// 6th parameter should be true in case of changing EPC ID it self i.e. source and target both is EPC
boolean useTIDfilter = memory_bank == MEMORY_BANK.MEMORY_BANK_EPC;
reader.Actions.TagAccess.writeWait(tagId, writeAccessParams, null, tagData, true, useTIDfilter);
} catch (InvalidUsageException e) {
System.out.println("INVALID USAGE EXCEPTION: " + e.getInfo());
e.printStackTrace();
return false;
} catch (OperationFailureException e) {
//System.out.println("OPERATION FAILURE EXCEPTION");
System.out.println("OPERATION FAILURE EXCEPTION: " + e.getResults().toString());
e.printStackTrace();
return false;
}
return true;
}
With
Password being 00
sourceEPC being the Tag ID obtained after reading
Memory Bank being MEMORY_BANK.MEMORY_BANK_USER
target data being "8426017056458"
offset being 0
It just keeps giving me "GetStatus Write RFID_API_UNKNOWN_ERROR data(x)- Field can Only Take Word values" and I have no idea why this is the case, nor I know what a "Word value" is, and i've searched for it. This is all under the "OperationFailureException", as well. Any help would be appreciated, as there's almost no resources online for this kind of thing.

Even this question is a bit older, I had the same problem so as far as I know this should be the answer.
Your target data "8426017056458" length is 13 and at writeAccessParams.setWriteDataLength(writeData.length()/4)
you are devide it with four. Now if you are trying to write the target data it is longer than the determined WriteDataLength. And this throws the Error.
One 'word' is 4 Hex => 16 Bits long. So your Data have to be filled up first and convert it to Hex.

Spark-Scala Unable to infer schema (Defer input path validation into DataSource)

SPARK-26039
While loading empty orc folder. Anyways to bypass this.
val df = spark.read.format("orc").load(orcFolderPath)

Getting this error may be orc reader trying to infer schema but i want to bypass this special case when somehow in repository blank folder came up but has to be checked.
try {
spark.read.format("orc").load(path)
} catch {
case ex: org.apache.spark.sql.AnalysisException => {
null
}
}
Tried by this way to catch exception. Any other way would be helpful

got one more solution seems like...this is also not best one...
import org.apache.hadoop.conf.Configuration
import org.apache.hadoop.fs.{FileSystem, Path}
def pathStatus(path: String): Boolean = {
val config: Configuration = new Configuration()
val fs: FileSystem = FileSystem.get(config)
if (fs.globStatus(new Path(path)) == null) {
false
} else {
true
}
}

Sonar WS : How to get the total unresolved bugs count using Sonar Webservice

I am trying to get the total number of unresolved bugs and Vulnerabilities in the particular project using sonar-ws-5.6.jar.
I tried to pass the type as BUG to the search query. But still I am getting all the unresolved stuff. It is not taking the parameter type.
How to get the exact number of bugs and Vulnerabilities using Webservice?
Here is my code to connect to sonar and get the data.
import java.util.ArrayList;
import java.util.List;
import org.sonarqube.ws.Issues.SearchWsResponse;
import org.sonarqube.ws.client.HttpConnector;
import org.sonarqube.ws.client.WsClient;
import org.sonarqube.ws.client.WsClientFactories;
import org.sonarqube.ws.client.issue.SearchWsRequest;
public class SonarTest {
static String resourceKey = "com.company.projectname:parent";
public static void main(String[] args) {
try {
// Get Issue
HttpConnector httpConnector = HttpConnector.newBuilder().url("http://localhost:9000").credentials("admin", "admin").build();
SearchWsRequest issueSearchRequest = new SearchWsRequest();
issueSearchRequest.setPageSize(1000);
issueSearchRequest.setResolved(false);
List<String> bugTypesList = new ArrayList<String>();
bugTypesList.add("BUG");
issueSearchRequest.setTypes(bugTypesList);
WsClient wsClient = WsClientFactories.getDefault().newClient(httpConnector);
SearchWsResponse issuesResponse = wsClient.issues().search(issueSearchRequest);
System.out.println(issuesResponse.getIssuesList());
System.out.println("DONE");
} catch (Exception e) {
e.printStackTrace();
}
}
}
Note: I am using sonarqube 5.6 with Java 1.8
As of now I am iterating the response and getting the count
List<Issue> issueList = issuesResponse.getIssuesList();
int bugCount = 0;
for(Issue issue : issueList){
if(issue.getType() == RuleType.BUG){
bugCount ++;
}
}

Well, you caught a bug ! I used your code and found out that the types parameter was not properly passed from the WSClient to the actual HTTP query.
So thanks for sharing your issue, SONAR-7871 is opened to have it addressed.

I am using ComponentWsRequest to get the total number of bugs
We can pass the metric key to get the required value.
Here is the code which gives me the total number of bugs.
List<String> VALUE_METRIC_KEYS = Arrays.asList("bugs");
ComponentWsRequest componentWsRequest = new ComponentWsRequest();
componentWsRequest.setComponentKey(resourceKey);
componentWsRequest.setMetricKeys(VALUE_METRIC_KEYS);
ComponentWsResponse componentWsResponse = wsClient.measures().component(componentWsRequest);
List<Measure>measureList = componentWsResponse.getComponent().getMeasuresList();
for(Measure measure : measureList){
System.out.println(measure);
}
We can use any of the metric keys to get the respective values:
"quality_gate_details","reliability_rating","reliability_remediation_effort","vulnerabilities","security_rating","security_remediation_effort","code_smells","sqale_rating","sqale_debt_ratio","effort_to_reach_maintainability_rating_a","sqale_index","ncloc","lines","statements","functions","classes","files","directories","duplicated_lines_density","duplicated_blocks","duplicated_lines","duplicated_files","complexity","function_complexity","file_complexity","class_complexity","comment_lines_density","comment_lines","public_api","public_documented_api_density","public_undocumented_api","violations","open_issues","reopened_issues","confirmed_issues","false_positive_issues","wont_fix_issues"

Java ProgramCall.run hangs

Busy trying to Call RPG function from Java and got this example from JamesA. But now I am having trouble, here is my code:
AS400 system = new AS400("MachineName");
ProgramCall program = new ProgramCall(system);
try
{
// Initialise the name of the program to run.
String programName = "/QSYS.LIB/LIBNAME.LIB/FUNNAME.PGM";
// Set up the 3 parameters.
ProgramParameter[] parameterList = new ProgramParameter[2];
// First parameter is to input a name.
AS400Text OperationsItemId = new AS400Text(20);
parameterList[0] = new ProgramParameter(OperationsItemId.toBytes("TestID"));
AS400Text CaseMarkingValue = new AS400Text(20);
parameterList[1] = new ProgramParameter(CaseMarkingValue.toBytes("TestData"));
// Set the program name and parameter list.
program.setProgram(programName, parameterList);
// Run the program.
if (program.run() != true)
{
// Report failure.
System.out.println("Program failed!");
// Show the messages.
AS400Message[] messagelist = program.getMessageList();
for (int i = 0; i < messagelist.length; ++i)
{
// Show each message.
System.out.println(messagelist[i]);
}
}
// Else no error, get output data.
else
{
AS400Text text = new AS400Text(50);
System.out.println(text.toObject(parameterList[1].getOutputData()));
System.out.println(text.toObject(parameterList[2].getOutputData()));
}
}
catch (Exception e)
{
//System.out.println("Program " + program.getProgram() + " issued an exception!");
e.printStackTrace();
}
// Done with the system.
system.disconnectAllServices();
The application Hangs at this lineif (program.run() != true), and I wait for about 10 minutes and then I terminate the application.
Any idea what I am doing wrong?
Edit
Here is the message on the job log:
Client request - run program QSYS/QWCRTVCA.
Client request - run program LIBNAME/FUNNAME.
File P6CASEL2 in library *LIBL not found or inline data file missing.
Error message CPF4101 appeared during OPEN.
Cannot resolve to object YOBPSSR. Type and Subtype X'0201' Authority
FUNNAME insert a row into table P6CASEPF through a view called P6CASEL2. P6CASEL2 is in a different library lets say LIBNAME2. Is there away to maybe set the JobDescription?

Are you sure FUNNAME.PGM is terminating and not hung with a MSGW? Check QSYSOPR for any messages.
Class ProgramCall:
NOTE: When the program runs within the host server job, the library list will be the initial library list specified in the job description in the user profile.

So I saw that my problem is that my library list is not setup, and for some reason, the user we are using, does not have a Job Description. So to over come this I added the following code before calling the program.run()
CommandCall command = new CommandCall(system);
command.run("ADDLIBLE LIB(LIBNAME)");
command.run("ADDLIBLE LIB(LIBNAME2)");
This simply add this LIBNAME, and LIBNAME2 to the user's library list.

Oh yes, the problem is Library list not set ... take a look at this discussion on Midrange.com, there are different work-around ...
