Windows Startup

[JediKnight2]

Why would a .jar file not startup if a key was set in
HKLM\Software\Microsoft\Windows\CurrentVersion\Run

The location is correct...I have even tried to convert it into an exe
using Launch4j and it wont start using a registry key..

Don't know, but Install4j, made by the same people, has an option that
will let you start a java app as a service. Might be a better option.

Why would a .jar file not startup ...

Any number of reasons. Does it work from the command line?

[JediKnight2]

Yup...starts by double clicking as well...in addition, if I throw a
shortcut into the startup folder it starts...

 

[Andrew Thompson]

Yup...

Please refrain from top-posting.

...starts by double clicking as well...in addition, if I throw a

OK - that rules out my immediate expertise.

Can you enable logging on it?
Does it *produce* any log?

A couple things that could cause it to not work:

1) Since Java requires a a classpath to work correctly it is possible
that when the items listed in the registry to automatically start the
classpath isn't set and so java errors out trying to run your jar.
Whether this is null and void by converting it into an exe using
Launch4j I don't know since I don't know how that works.

2) Try specifying the full path to your java.exe and specify the data in
the Run key by using the normal syntax for running a jar with java.exe
(by using -jar switch):
"c:\Program Files\java\jre1.6.0\bin\java.exe" -jar yourjar.jar


Also look at the Application/System event logs to see if there is
anything useful in there.

No errors in the logs...when I run the command java -jar
"D:\Program Files\TGDTJ\tgdtj.jar" as the registry key I get the
following error


java -jar "D:\Program Files\TGDTJ\tgdtj.jar" Exception in thread "main"

What's in the key? To be safe, you might want to use

%JAVA_HOME%\bin\javaw.exe -jar <path-to-jar>

Just putting the path to the jar might not work.

Somebody declared a method as native in your code but didn't
fulfill the contract?

You've got a big hurtin' on your Jedi Sword right about now.

Oh for goodness sake! If you had an error message, why didn't you say
so to begin with? It looks like the problem is with one of two things:
(1) there's a library somewhere that can't be found at that point in
startup (perhaps it's on a network drive, or there's an environment
variable that hasn't been set yet), or (2) this library from beq.ca (Bay
Equities Incorporated?) doesn't work on system startup.

If you're not a programmer, as you later said, then the best thing to do
is probably to contact some kind of technical support with whoever
gave/sold you the program.
