Java Examples (Running ooRexx Scripts from Java)
Hint: if you wish to look at the ooRexx code with syntax highlighting, then you can
use the free and open-source editor "[g]vim"
, which is available for practically
all platforms and can be downloaded from its homepage at
http://www.vim.org/.
- . <directory> (List of this directory)
- Display all of this directory's files and directories.
- .. <directory> (List of parent directory)
- Display all of the parent directory's files and directories.
- handlers <directory>
- Root of Rexx handler samples (cf. "rexxapi.pdf", sections
1.15. Rexx Exits Interface and 1.16. Command Handler Interface).
- InvokeRexxFromJava.java
- A Java demonstration program to show, how easy it is to invoke a Rexx program, supply
arguments to it and retrieve a return value.
- JavaRunRexx_01.java
- Demonstrate how to invoke an ooRexx program and supply it
a Java object to interact with.
[NetRexx version: nrxRunRexx_01.nrx.]
- JavaRunRexx_02.java
- Demonstrate how to invoke an ooRexx program and supply it
a Java object to interact with. This version first causes
the ooRexx package
BSF.CLS
to be loaded into the ooRexx interpreter
instance, such that the next ooRexx script that gets executed
already has full access to the public classes and routines of
the BSF.CLS
ooRexx package.
[NetRexx version: nrxRunRexx_02.nrx.]
- JavaRunRexx_03.java
- Demonstrate how to interact with a Rexx object from Java.
[NetRexx version: nrxRunRexx_03.nrx.]
- JavaRunRexx_04.java
- Demonstrate how to fetch and interact with a Rexx condition object from Java.
[NetRexx version: nrxRunRexx_04.nrx.]
- JavaRunRexx_05.java
- Demonstrate how to setup a
.host
directory in Rexx from Java, which then
receives Java objects for use in Rexx programs; in addition a value is saved in
.host
by Rexx under the index REXX.HEY
that upon return
is fetched from Java.
[NetRexx version: nrxRunRexx_05.nrx.]
- JavaRunRexx_06.java
- Demonstrate how to use the context of a Rexx routine (i.e. all public
routines and public classes available to it) for another
Rexx routine.
The first routine requires BSF.CLS
which adds
public routines and public classes which then are made available to Rexx
routines that get created and executed later via Java. In addition the
ooRexx standard streams get redirected to the Java standard streams by
calling the public routine bsf.redirectTo
.
Then another Rexx routines gets defined to use the first package, and in addition
defines a public routine named test
.
Finally, the last Rexx routine demonstrates getting access to the package
of the second routine which makes its public routine named test
accessible. In addition the last routine is called twice, once without
Java supplied arguments, once with Java supplied arguments.
[NetRexx version: nrxRunRexx_06.nrx.]
- javax.script (a.k.a. "jsr-223": "Java Specification Request 223", the expert group that defined the Java scripting framework)
- Demonstrates how to take advantage of the Java scripting framework
(cf. Java package e.g. at "javax.script")
introduced with Java 6.
