host variable for the file name is defined with a length of 63 (very short since it contains also the path). I don't know if I can safely extend the length of the RPG variable.
Java strings can be extremely long (megabytes!) so you don't have to worry about making your RPG string too long for Java to handle.
But, you'll want to look at your prototype for the java String constructor. Make sure that it allows strings as long as the one you want to pass. For example, here's the one that I use (if you're using my HSSF tools, this is in HSSF_H):
midrange.com
D new_String PR like(jString)
D EXTPROC(*JAVA
D :'java.lang.String'
D :*CONSTRUCTOR)
D create_from 1024A VARYING const
This lets you specify a string that's up to 1024 characters long. If you
need a longer one than that, you could change teh "create_from" parameter
definition to a higher number, such as 65535...
But, AFIAK, that's the only limit on how big a string can be... For sure, 63 bytes is awfully small, it should be no problem to make it bigger than that!
