EDIT: When renaming ProfileService.class to ProfileService2.class, it worked... Name clash somewhere?
When trying to deploy my application, I get the following exception:

As you can see, nothing is weird with ProfileService, just a very normal session bean. It's also worth to mention that I can still use the application, regardless of the exception.
What could be the cause?
Using JBoss 6 with Weld.
Seems like a bug in JBoss, Naming a class ProfileService was apparently not allowed. Renaming the class solved the problem.

I am a newbie to spring boot.I have created a crud operation and the insert operation is working properly. I have a challenge on the update operation , the program is giving an error on the web page
Whitelabel Error Page This application has no explicit mapping for /error, so you are seeing this as a fallback.Wed Jul 22 20:39:03 CAT 2020 There was an unexpected error (type=Bad Request, status=400)
and the following error from the console
Resolved [org.springframework.web.method.annotation.MethodArgumentTypeMismatchException: Failed to convert value of type 'java.lang.String' to required type 'long'; nested exception is java.lang.NumberFormatException: For input string: "saveEmployee"]
how can I solve the problem?

Can you also post you entity class?
From the error it is telling that the required type is long but it is getting it as string? It may be possible that you have mentioned your id as string instead of long.
Also try to add th:action="#{/saveEmployee}" to be exact as that of your /saveEmployee endpoint
Add "/" in form th:action, like so -> th:action="#{/saveEmployee}"
Also check your crud repository, insted of long use Long.
I solved the problem
I added a / to make th:action="#{/saveEmployee}" and changed long to Long in my controller Class in the following request
#GetMapping("/showFormForUpdate/{id}")
public String showFormForUpdate(#PathVariable( value="id") Long id, Model model) {
//get the employee from the service
Employee employee =employeeService.getEmployeeById(id);
// set the employee to pre-populate the form
model.addAttribute("employee", employee);
return "update_employee";
}
and this solved the problem
By using this in reactive forms
<form #branchForm [formGroup]='branchForm'>
I got some errors as
Error: Uncaught (in promise): Error: Template parse errors:

I have imported all the necessary modules such as ReactiveFormsModule,Fromgroup etc
import { FormsModule, ReactiveFormsModule } from '#angular/forms';
and included these in imports also
import ReactiveFormsModule from #angular/forms
Is needed to be imported into your components module and added to your imports as well.
import { ReactiveFormsModule } from '#angular/forms';
#NgModule({
imports: [
// other imports ...
ReactiveFormsModule
],
})
export class AppModule { }
To fix this error, you just need to import ReactiveFormsModule from #angular/forms in your module.
After submitting a form on the profile page it goes to the controller where it then updates a database to then redirect back to the same page that the form was on. However i get an error trying to return to the same page. I can however redirect to another page without any issues?
Any help would be great.
The Form
<form action="controller" method="post">
Link Name:<br>
<input type="text" name="createLinkName">
<br>
Link Content:<br>
<input type="text" name="createLinkContent">
<br>
<input type="hidden" name="command" value="createLink" />
<input type="submit" value="Submit">
</form>
Catching The Form Request
else if (command.equals("createLink"))
{
String linkName = request.getParameter("createLinkName");
String linkContent = request.getParameter("createLinkContent");
User sessionU = new User();
sessionU = (User)request.getSession().getAttribute("user");
int userID = sessionU.getId();
System.out.println(userID);
createLink(request, response, linkName, linkContent, userID);
}
createLink()
protected void createLink(HttpServletRequest request, HttpServletResponse response, String name, String content, int userID) throws IOException, ServletException
{
profileHandler ph = new profileHandler();
ph.createLink(request, response, name, content, userID);
request.getRequestDispatcher("profilePage.jsp").forward(request, response);
}
Handler that deals with the sql
public class profileHandler {
private final DatabaseManager dbMgr;
public profileHandler()
{
this.dbMgr = new DatabaseManager();
}
public void createLink(HttpServletRequest request, HttpServletResponse response, String name, String content, int userID)
{
dbMgr.establishConnection();
String CREATE_LINK = "INSERT INTO linkedaccounts (linkname, linkaddress, userid) VALUES ('" + name + "', '" + content + "', " + userID + ")";
dbMgr.prepareStatement(CREATE_LINK);
dbMgr.executePreparedStatement();
dbMgr.releaseConnection();
}
There isn't a problem with the sql as it is updated the Database just fine. Just wont allow me to eith stay on the same page as the form or just redirect back to it!
Thanks Again.

Search datatosearch = requestData.get();
// String criteria="shop";
String criteria = datatosearch.criteria;
SearchResult result = new SearchResult();
result.criteria = criteria;
result.keyword = datatosearch.keyword;
if (criteria == "shop") {
List<Shop> shops = Shop.findByShopName(datatosearch.keyword);
result.shops.addAll(shops);
}
else if (criteria == "product") {
List<Shop> shops = Product.findByShopName(datatosearch.keyword);
result.shops.addAll(shops);
}
return ok(views.html.search.results.render(result));
}
}
if I do String criteria="shop" or String criteria="product" in my SearchController.java then it works fine, meaning my model query is correct, but if I execute the above code with String criteria = datatosearch.criteria it shows a blank screen.
I am using play framework, I am really stuck at this and any help would be appreciated.
You are comparing strings with the == operator which is a no-no. Change your string comparisons to use String.equals so you are actually comparing the values instead of object references.
if (criteria.equals("shop") {
...
}
else if (criteria.equals("product") {
...
}
You probably also want to add some validation to check that criteria isn't NULL.
I would like to have a list of entries which I can shift/order and at the same time editable.
So I tought to combine p:orderList with p:inplace this way:
<p:scrollPanel style="width:300px;height:100px" scrollMode="native">
<p:orderList var="title" value="#{detailModel.afterObject.metadata.getTitlesAsList()}" type="definition">
<f:facet name="description">
<p:inplace id="basic" editor="true">
<p:inputText value="#{title.value}" required="true"/>
</p:inplace>
</f:facet>
</p:orderList>
</p:scrollPanel>
but I get the following error:
java.lang.NullPointerException

Do I miss something or it is not possible doing so?
If I use :dataList instead I don't get the error, but it has a strang behaviour; when I click on an entry, all the entries become editable, but then they remain in the edit-mode and nothing more is possibe...
Any suggestions?
EDIT
Here is the bean:
public class DoiDetailModel extends DetailModel
{
private List< String > selectedTitles;
private List< String > selectedCreators;
private String title;
private String creator;
public DoiDetailModel()
{
super();
}
public List< String > getSelectedTitles()
{
return selectedTitles;
}
public void setSelectedTitles( List< String > selectedTitles )
{
this.selectedTitles = selectedTitles;
}
}
