Re: Problem in defining a Java method for RPG/ILE

["Marvin Radding" <marvin.radding@xxxxxxxxxxxxxxxxxxxxx>]

Scott,

When I included the InputStream parameter in the definition, the
compiler tells me that there are fewer parameters than the definitions
calls for. What is the assumed parameter that I need to pass it?

My C specs are:

c                   eval      logoimage = new_String('/mr0473/logo.jpg')

c                   eval      InputStream =
new_FileInputStream(logoimage)   
c                   eval      picarray = toByteArray(InputStream)


Now I am getting more confused. If I define it without the InputStream,
I can call it as I have before. If I define the InputStream as part of
the definition, then I don't know what to use as the assumed parameter.
This is suppose to create an object. What parameter is there that I need
to pass it?

Thanks,
 
Marvin

You appear to have forgotten the InputStream parameter.
