I have an existing set of QTP regression tests that I wrote and have executed through several regression test cycles successfully. I have a JavaWindow that contains several JavaTables where I parse the table data into an array and verify it against the expected results in Excel spreadsheets.
In the current test cycle, the JavaWindow (which contained the JavaTables that I could read and verify) has now changed to a class of Window, and QTP sees this Window as simply one object. I can no longer verify the table data inside the window.
What may have happened that could cause the QTP class of the JavaWindow to change to a class of Window? No code changes have been made to this window, and I have verified that the Java versions on both my test box and app server have not changed and are valid for the current version of QTP.
Any insight into this issue would be greatly appreciated.
It sounds like the Java addin in QTP isn't working. There can be several causes for this.
QTP was loaded without selecting the Java addin in the addin manager
The test's Record and Run settings don't include your application
The Java application was opened before QTP (so QTP wasn't able to hook this application)
Along with the other answer, it might also happen, when you mess up your with Environment Variables. Lets say you installed StarTeam (it happened to me) recently which updates some of the existing environment variables set by QTP like JAVA_OPTIONS.
If it was working before & you could not figure out the issue, i would suggest you to repair UFT (using control panel options).

I encounter some very strange behavior and I don't know how to handle it.
I suspect that the behavior started to reproduce after last Windows upgrade. But I am not sure if it has anything related to it. (I discovered it when I tried to run maven, which uses java)
The behavior is the following: when run java (e.g. java.exe -version) from command line, it does nothing (like below). The process looks like it is hanged.
enter image description here
I did the following tests:
make a clone of java.exe (e.g. jv.exe) and run it. It works.enter image description here
rename another application to java.exe (e.g. processmonitor.exe to java.exe). When run application, it doesn't open.enter image description here
renamed java.exe to java.exe.bkp and make a link 'java.exe' to 'jv.exe' (which works), and the process is hanged.
make another link java1.exe to jv.exe and it works.enter image description here
did all the operations with&without network, and no difference (java.exe doesn't work, the others work)
restart windows in 'save mode' (+/- network) and java.exe works
I disabled the firewall from windows, and/or I added rules for java.exe. It doesn't work.
Initially I had many JVMs installed. I uninstalled all of them and installed only the one in images. All above tests are made after new installation.
Also, I observed that every time I run java.exe (but not when I run jv.exe or java1.exe) there is a new file java.exe.XXX.dat created in c:\Users\user.name\AppVerifierLogs.enter image description here Searching on google, it seems that is some kind of log file, which can be viewed with this application (https://learn.microsoft.com/en-us/windows-hardware/drivers/devtest/application-verifier) but I don't find the standalone application. Maybe it is already installed in the system, but I don't know where or how to enable it.
It seems that for some reason, the Windows is blocking all processes named 'java', no matter if it is actually the java program or any other application. But I'm out of ideas regarding what could be the cause, or how to continue to investigate.
If anyone can help me, I will be grateful to him.
Thank you.
I have already asked this and was heavily downvoted. Unfortunately, I still can't solve it. I don't know what I do, but sooner or later I loose an ability to run java applets and java web start applications in all browsers.
Here is an example what is happening.
I am opening page with applets http://csis.pace.edu/~bergin/Java/applets.htm and getting the following picture:
with signs plugins were blocked. I am trying to unblock
which causes another dialog
after OK I have another
next
if clicked
And so on.
Applet doesn't run.
After dancing with PATHes, Java updates and so one, once I can have applet run. But sooner or later I will stuck in this position again.
I would like to know, is it possible to exclude this situation in principle?
I mean I don't want to disable security at all, but I mean that in case my explicit permission everything should run. Is it possible to do that?
UPDATE
First of all, I don't understand, why can't I run applet on outdated java if I want?
I am a human and robots should obey me! :)
Suppose I wish to debug my applet on old version of java, why not?
Second, there is no information about what version it thinks I have and what version it wants?
Without this information it is possible that there is just a bug in version detection mechanism.
I have multiple versions of Java in Program Files since I am a Java developer. Then how can I know which one it uses?
UPDATE 2
I have updated my Java from 1.8.0_20 to 1.8.0_25 and now situation have changed, but applets are sill impossible to run.
The proof I have "latest" java:
The proof I have added the site above to exclusions list:
The effect of applet run:
(applet not runs)
Clicking details result:
(no any details in fact)
So, what to do?
UPDATE 3
This site is not working: http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=2012VP113;orb=1;cov=0;log=0;cad=0#orb
(show orbit diagram)
Reloading/restarting browser does not help.
I looked at your html source and realized you're using the .class file directly instead of wrapping it in a jar file. This is what you have:
<applet code="GSort.class" width=700 height=400>
I think applets no longer work when using .class files directly due to new security requirements. They have to be wrapped in jar files because you need to add some security settings to the meta-inf folder of the jar file. Here is how oracle recommends deploying an applet:
https://docs.oracle.com/javase/tutorial/deployment/applet/deployingApplet.html
Edit:
I tried again with adding the site url to the Java security exception list and this time I got it to work! It looks like chrome stays in memory after exiting so changing Java security doesn't affect it unless you shut down chrome completely and restart it. Easiest way is to use Internet Explorer. Try it with Internet Explorer and it should work (assuming that you still have the site added under java security exception list).
Hi I am writing an SWTBot test which launches a file from a hyperlink using Program.launch. From the bot test I need to check that the 3rd party application opened to display the file. The only thing that seems obvious to me is checking that focus was lost on the underlying workbench but all focus, enabled and visible assertions remain true. Does anyone have any assertion ideas here?
I would recommend to avoid letting the test spawn a process at all. You'll have to wait for the process, kill that process in tear down to leave a clean environment, etc.
If possible I'd rather mock the program launching code during tests and verify that it gets executed if the hyperlink was selected.
But if you really want to test that the 3rd party app was launched , I would rather check if a new process was created. There seems to be neither support in the JRE nor a library to list OS processes so that you probably have to resort to System.exec() ps or tasklist.exe, depending on the OS you are running on.
"Debugception!"
You may notice that within the first 15 seconds of this YouTube video (from 1:01:01 to 1:01:16), Markus Persson (aka "Notch", creator of Minecraft) has somehow managed to save/update an application and attach a debugger to it while it was already under the process of being debugged, supposedly all with a simple keyboard shortcut. The previously coded application somehow magically became the newly edited one, and seemingly without relaunching it or spawning a new process... It's possible that this is just some form of locally remote debugging, but something about it just doesn't seem quite right.
I've spent several days Googling and asking around on how he was able to do this, yet to no avail. I've found no such option under Eclipse preferences, and whenever I try to save & debug an already running application, it simply launches a separate instance of the newly updated application, side-by-side with the older, outdated one.
Am I missing something? How was this possible?
How was he able to utilize such an astounding, powerful debugging feature?
Thanks in advance!
Update
Okay, so this appears to be a standard feature specific to Eclipse.
Coming from a background in NetBeans and Visual Studio, I'm astounded that this doesn't seem to exist elsewhere (or at least in NetBeans!)...
This is a built-in feature of Eclipse. If you edit a method while the program is running in debug mode, it will compile the new method, and replace the old method with the new version. If some thread was already running that method, it will jump back to the beginning (AFAIK; this might only happen when the program is paused).
You don't need to re-launch the program or set any special preferences. Just edit and save, and the magic will happen.
Eclipse can't always figure out how to merge your changes into the running program - usually if you changed anything outside a method body (including the method's parameters or return type). In this case, you will get a warning dialog, with the option to stop the program, restart the program or ignore the changes.
I am unable to run more than one instance of java webstart at any given time.
For example, I am unable to run both the production & QA instance of an application at once, both of which are launched via java webstart. Additionally, I am unable to run the java webstart cache viewer at the same time as either the production or QA instance of my application.
I am however able to run any of the above three webstart launches when they are run in isolation of each other. When I try to bring up a second option, I see the 'Java Loading...' screen which then disappears and nothing happens.
Additionally, I have tried to delete the webstart cache (via the java webstart cache viewer) and I receive the following error regardless of which JRE I point to:
"Bad installation. Error invoking Java VM (execv)
'path to my javaw.exe'"
I expect both the problems I mention above are interlinked. I do not believe I have changed any configuration recently and I have been happily running java webstart for years.
Has anyone seen such a problem before?
Thanks,
Jack
EDIT: When the second instance of webstart attempts to run, during the display of the 'Java Loading...' screen I can see in the task manager that a new javaw.exe process is spawned. This process almost immediately dies though. I'm not sure how to inspect the failure in that process, but I expect it is similar to the failure when trying to clear my cache through the webstart cache viewer.
You may be able to use javaws from the command line to run a second instance in -offline mode. The verbose option is handy, too.
javaws -offline -verbose MyApplication.jnlp
I think it is because both instances of the application use the same folder as current working directory. I do not remember exactly but it is somewhere under user home and the folder contains the application name or something...
So, if this is correct the solution is to change the application name like "My Application - QA" vs. "My Application" used on production.
The name is somewhere in jnlp.xml.
The reason may be the startup parameters for client java/javaw, which do not allow to run more than one instance of Java. For example because of set debug port. These parameters can be set in the command line or in the Java Control Panel -> Java -> button View.
