you need to tell configure where they are. You can either use the

Previously this was done via the environment variables JAVA_HOME, which

still works for backwards compatibility.

Here is how to add a new function to the Java API for PLplot:
101
112
java rather than C. Note the raw interface only allows two-dimensional xg,
102
113
and yg arrays to plcont, plshades, and plshade. The options of no xg, yg,
103
114
and one-dimensional xg, and yg should also be allowed for the UI interface.

Also note the raw interface to plParseOpts demands you must be explicit

Also note the raw interface to plparseopts demands you must be explicit

116
about ORing in pls.PL_PARSE_NOPROGRAM to the parse mode parameter. This
106
117
idiosyncrasy of Java should be hidden for the UF interface.
110
121
user-friendly simplified argument list variations that have been implemented
113
* Each example has a rather ugly combination of two commands:
115
PLStreamc plsdummy = new PLStreamc();
116
plplotjavac pls = new plplotjavac();
118
The first one dynamically loads the wrapper library (with the stream stuff
119
commented out because the plplot API is not available to that class at the
120
moment), and the second one loads the plplotjavac wrapper made by swig which
121
then pulls in everything else that is required. Obviously, this should all
122
be done with one command where we refer to PLStream, the user-friendly
123
wrapper which in turn wraps PLStreamc, which in turn (after loading the
124
library) wraps plplotjavac and then finishes with the stream stuff that
125
Geoffrey put in for the old interface. But it is going to require somebody
126
(that word again....;-)) more expert in Java than me to implement this. As
127
I said above, I can fill out all the required argument list variations once
128
somebody shows me how to make just one of them.
130
124
* Only the default java double-precision can be used from Java. That is
131
125
what the examples use (by default) and that is what works. I believe the way
132
126
to do this properly with swig is simply to make both single and double
147
141
what is done for the Tcl interface rather than the preferred complete
148
142
callback approach used for the Python interface.
