Hallo, everyone,

 

i wrote a program before 8 months but it can't run now.

 

there are some code of my codes

 

public Histcheck(String start,String over){

try {
theUFSession=(UFSession) SessionFactory.get("UFSession");

lw=theUFSession.ui();
lw.openListingWindow();
SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
beginn=sdf.parse(start);
end=sdf.parse(over);
this.testYear=beginn.getYear();
} catch (NXException e) {
out.append("NX failed in Construct");
protokoll.ta.append("NX failed in Construct");
e.printStackTrace();
} catch (RemoteException e) {
out.append("Remote failed in Construct");
protokoll.ta.append("Remote failed in Construct");
e.printStackTrace();
} catch (ParseException e) {

out.append("Parse failed in Construct");
protokoll.ta.append("Parse failed in Construct");
e.printStackTrace();
}
}

 

it returns:

 

nxopen.NXException: Search Directory for Manifest files can not be opened

...

Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException

 

Also, i can't get the UFSession.

 

i use java of version 1.8.25

 

ps: my program runs on other pcs in the labor, but not on my pc.

 

Thank you in advance.

I do not use java but surely the lines of code

 

lw=theUFSession.ui();
lw.openListingWindow();

 

cannot be correct.  The first line defines lw as the ui interface so that no way the second line can open the listing window?

thanks for your answer.

i have defined that UFUi lw=null;

my code should not have problem, because it runs on other pcs.

just not run on my pc.

return the message: nxopen.NXException: Search Directory for Manifest files can not be opened.

If anybady hat this problem too, you can check the Java Version wenn it even doesn't work, you can also your windows new install.

My program works after i installed windows new.

That solution seems a bit... extreme.
