问题
I have a simple MVC web application, which was running locally without problems 3 weeks ago.
When I now open the application in Netbeans and run it, everything seems to work fine as well. However, when I go to the browser (in my case google chrome) to look at the app's frontend (at http://localhost:8080/optimizer), I get the following error message:
HTTP Status 404 - Not Found
In Chrome's javascript console the following error message is given:
optimizer:1 Failed to load resource: the server responded with a status of 404 (Not Found)
"optimizer" is the name of the app. (What's the point of the "1" in "optimizer:1"? ... I don't get this either.)
The server (payara) is running:
I can also reach the server's admin page:
However, somehow the server cannot seem to find the application, although 3 weeks ago everything worked fine ... I just don't get it. What's wrong? How can I fix this?
UPDATE:
Clicking on "List Deployed Applications" in Payara's Admin Console reveals that my app is not(!) deployed.
I tried to deploy it by clicking on "Deploy an Application" -> "Choose file". I selected the jar-file "optimizer-1.0-SNAPSHOT.jar", selected Type "EJB Jar", then clicked on OK.
I got this error message:
Archive type of /private/var/folders/hh/hgq7wrjn5d51gy2tkbxkkbwh0000gn/T/optimizer-15075570634779987058.0-SNAPSHOT.jar was not recognized
How can I deploy my app? And why did it work automatically before and now it doesn't work any more?
UPDATE 2:
A difference I realise compared to before (3 weeks ago) is that the browser doesn't open automatically any more when I run the app. Furthermore, Google Chrome used to be the IDE'S default browser ... now there is just a grey globe and I can no longer choose Chrome as my browser:
UPDATE 3:
I just noticed there is an error message that appears when the server is started (it's in the middle of hundred of rows of log output so I didn't notice it at first):
UPDATE 4:
-> NetBeans IDE 11.2 -> Payara Server 5.193
回答1:
Error clearly shows, server is not able to recognize archive type of jar,
Archive type of /private/var/folders/hh/hgq7wrjn5d51gy2tkbxkkbwh0000gn/T/optimizer-15075570634779987058.0-SNAPSHOT.jar was not recognized
From payara blog,
If you set “Location” by “Packaged File to Be Uploaded to the Server”, the suitable type would be selected.
So, the suitable type would be selected automatically.
Also, optimizer-15075570634779987058.0-SNAPSHOT.jar is not an original jar optimizer-1.0-SNAPSHOT.jar
It seems that issue is with the path of an archive, from thread
Code in uploadFrame.jsf:
<sun:form id="form">I probe to change it to:
<sun:form id="form" enctype="multipart/form-data">in uploadFrame.jsf into console-common.jar file. And it works.
You can try with changing uploadFrame.jsf into console-common.jar file.
(Not sure if chrome takes care of this, as it was working for you with chrome).
You may also want to try manual deployment,
install-directory/bin/asadmin deploy PATH_TO_ARCHIEVE/optimizer-1.0-SNAPSHOT.jar

Ok, I now found out how to run the app locally without problems: by creating a .war file instead of a .jar file - now I can run the app again without problems.
