Calling COM method with signature [VT_BSTR, VT_BYREF|VT_I2] fails
-----------------------------------------------------------------
Key: JRUBY-5404
URL: http://jira.codehaus.org/browse/JRUBY-5404
Project: JRuby
Issue Type: Bug
Components: win32ole
Affects Versions: JRuby 1.6RC1
Environment: jruby 1.6.0.RC1 (ruby 1.8.7 patchlevel 330) (2011-01-10
769f847) (Java HotSpot(TM) Client VM 1.6.0_23) [Windows XP-x86-java]
jruby-win32ole 0.8.3
WinXP SP3
Reporter: Colby Hart
Assignee: Thomas E Enebo
Priority: Minor
Calling the following works with ruby 1.8.6 [i386-mswin32], but fails with
JRuby. I tried it on a few systems with the same configuration.
# VOID LoadObjects
# BSTR arg0 --- Configuration []
# I2 arg1 --- errCode []
def LoadObjects(arg0, arg1=0)
ret = _invoke(1, [arg0, arg1], [VT_BSTR, VT_BYREF|VT_I2])
@lastargs = WIN32OLE::ARGV
ret
end
The exception is:
Java::OrgRacobCom::ComFailException: A COM exception has been encountered:
At Invoke of: 1
Description: Type mismatch.
