The following error appear when I'm using NavigableSet to get the decending key set of a TreeMap:
[ERROR] [workflow] - Line 159: No source code is available for type java.util.NavigableSet<E>; did you forget to inherit a required module?
[ERROR] [workflow] - Line 159: The method descendingKeySet() is undefined for the type TreeMap<Integer,String>
Here is the code I use:
NavigableSet<Integer> nmap = selectedRow.descendingMap();
Does someone know where the error comes from ?
(For information i've imported the right class: java.util.NavigableSet )
I don't have enough rep for a comment... sorry. What version of GWT are you using? It looks like there is a bug here:
https://code.google.com/p/google-web-toolkit/issues/detail?id=4236
Fixed in 2.7.0 RC1

Hej.
First of all: sorry for maybe asking a very simple question, I am very new to Java.
Here is my problem: I updated the dependenciy of an ancient code from using net.sourceforge.htmlunit version 2.8 to 2.37.0 (this was recommended by the Github security bot).
Now my code is not compiling and throws two errors.
Here is the relevant code:
import com.gargoylesoftware.htmlunit.BrowserVersion;
import com.gargoylesoftware.htmlunit.WebClient;
...
WebClient webClient = new WebClient(FIREFOX_3);
webClient.setTimeout(50000);
HtmlPage page = webClient.getPage("http://king.smith.man.ac.uk/mcpred/");
First error:
[ERROR] ./MissedCleavageAnalysisAdaptor.java:[64,53] cannot find symbol
[ERROR] symbol: variable FIREFOX_3
Second error:
[ERROR] ./MissedCleavageAnalysisAdaptor.java:[65,26] cannot find symbol
[ERROR] symbol: method setTimeout(int)
I managed to avoid the first error by simply deleting the "FIREFOX_3". Using "FIREFOX" (= newest version of firefox) or "FIREFOX_78" instead did not work and threw the same error.
With the second error, I cannot see the problem. I tried other integers or first defining an integer int timeout = 50000; and webClient.setTimeout(timeout);. Always the same error occurs. It seems like the method setTimeout was not imported. However, this should be imported together with WebClient, shouldn't it?
Can you please give me a hint how to tackle these errors?
Thanks a lot!
Wow thats a huge jump 2.8 was released Aug 5, 2010 and 2.37 in January 28, 2020.
The current version is 2.46.0 rom January 2, 2021 - maybe it makes sense to directly migrate to this one.
If you have a look at the release notes you will find this line:
WebClient: deprecated setTimeout() and getTimeout(). Use webClient.getOptions() instead.
for the release 2.11. Means - you have to change your code like this:
webClient.getOptions().setTimeout(50000);
The whole release notes are available here https://htmlunit.sourceforge.io/changes-report.html
Getting below error when I am trying to run gatling.sh file. From my understanding getting compilation issue in RecorderSimulation.scala file while doing gatling.sh. Please see the below Error and help me

Please suggest solution
This error is due to the size of the scala file being too large. You need to keep number of requests in a method to under 100. I faced the same issue and resolved it by splitting the script into two methods.
You've managed to generate some piece of code that's too large with regard to the Scala language spec.
Please make sure you're using latest Gatling version (3.3.1 as of now) and upgrade if not.
If problem still happens, please reach out on Gatling community mailing list and provide your code.
When generating the Javadoc, it adds on prefix to the imported class name, as shown below on the first line 'java.lang'.
How to properly disable that?
Have tried adding -noqualifier in Other command line arguments in my IntelliJ popup window but the following error occurred:
javadoc: error - Illegal package name: "/Users"
Below is a snippet from the Javadoc I generated:
public TrainRoute(java.lang.String name,
int routeNumber)
Creates a new TrainRoute with the given name and number.
Should meet the specification of Route.Route(String, int)
Parameters:
name - The name of the route.
routeNumber - The route number of the route.
I know this is an old question, but still relevant. I am aware of two solution which can be used alone or in combination:
To suppress prefixes on java packages use:
-noqualifier java.*
To suppress prefixes and link to the actual Java docs use:
-link https://docs.oracle.com/javase/8/docs/api
Both suppress the java name qualifiers. The second also links to the Oracle docs.
See javadoc options docs for more info.
The Oracle Tutorial page for the Temporal Query show this example code.
- Code
TemporalQueries query = TemporalQueries.precision();
System.out.printf("LocalDate precision is %s%n",LocalDate.now().query(query));
When I compile this segment code, the Compiler throws the error:
- Error
TemporalQueryExample.java:8: error: incompatible types: TemporalQuery<TemporalUnit> cannot be converted to TemporalQueries
TemporalQueries query = TemporalQueries.precision();
^
TemporalQueryExample.java:10: error: no suitable method found for query(TemporalQueries)
LocalDate.now().query(query));
^
I don't know this java 8 documentation tutorial example is correct or not but I copy this code segment and paste my IDE then IDE throw the Error.
There is an error in the code. Look at what Lokesh has mentioned.
To further learn coding, make sure you understand the error properly. It will make your life easier. In this example, the error says: TemporalQuery<TemporalUnit> cannot be converted to TemporalQueries
If you check your code, <TemporalUnit> is not there, which is an indication that you have to place it somewhere and the right place to have it is mentioned by Lokesh.
You can go through this tutorial
Change this line TemporalQueries query = TemporalQueries.precision(); to this TemporalQuery<TemporalUnit> query = TemporalQueries.precision();
You can check this Java 9 documentation
I am using Eclipse Juno and Java.
I was trying to create a new list:
List myList = new ArrayList();
This had an error and the resolution on it was along the lines of change compiler to 1.7 which I accepted. The errror on this list creation line was corrected however I now have many errors thoughout the whole project on lines that were previously working. Some examples are:
class GetAccountAndCubsHandler<T> implements AsyncCallback<List<AccountAndCubs>>
Multiple markers at this line
- The hierarchy of the type GetAccountAndCubsHandler is inconsistent
- List cannot he resolved to a type
public class AccountCreationView extends Composite {
Multiple markers at this line
- The hierarchy of the type AccountCreationView is inconsistent
- Breakpoint:AccountCreationView
#SuppressWarnings("unused")
private String accountId;
First line - Multiple markers at this line
- SuppressWarnings cannot be resolved to a type
- The attribute valie is undefined for the annotation type SuppressWarnings
Second line - String cannot be resolved to a type
As you can imagine having my whole project adversely affected in this way is very disconcerting so any advice on how to recover would be greatly appreciated.
Regards,
Glyn

Ensure that a valid JRE or JDK is specified in your build-path.
Since you're using Eclipse, right-click on your project, then Properties → Java Build Path.
Perhaps you don't have a Java 7 JRE configured in the Installed JREs preference panel.
