Re: [Wrapper-user] Wrapper start problems on Linux

[Lars S. <Lar...@if...>]

Hi again

I am again trying the mentioned scenario, but with the parameters as:
wrapper.java.mainclass=special.start.class
wrapper.app.parameter.1=-"parameter to special start class"
wrapper.app.parameter.2=myStartClass

where myStartClass implements WrapperListener.
This works fine on Linux (Red Hat Enterprise Linux 5.5 64-bit with Java 
1.6.0 Update 22 64-bit).
On Windows 7 (64-bit with Java 1.6.0 Update 21 32-bit) it does not work, 
I get a lot of error messages in the log file about a timeout in waiting 
for a signal from the JVM.
Any help would be greatly appreciated.

When I try Integration method #1 I get an exception about that the 
WrapperSimpleApp can not access a member with modifiers "public static" 
in the special.start.class.
Thanks

Lars
