Tcl/Java interoperability with TclBlend 1.4.  A new precompiled binary for Windows.

Patrick Finnegan and  Mo Dejong.

Right Click for Tclblend:   tclBlend140Binary.zip

A new TclBlend 1.4 precompiled binary is available for Windows.  The binary is built from Tcl 8.4.13, Tcl Threads 2.6.3, and TclJava 1.4.  It provides full interoperability between Tcl and Java through the use of an embedded JVM and supports existing Tcl extensions or packages such as Expect, Tcom, Tk, Tcllib, TclX and Snack.  To install download the zip file and extract to your installation directory.  No compilation required.  Run a TclBlend script just like a Tcl/TK script.
   
C:\TclBlend\bin\jtclsh.exe oracleJDBCType4.tcl  -  connect to oracle using a jdbc driver and tclBlend.

TclBlend should be backwards compatible with all Tcl Scripts written to the Tcl 8.4.13 specification.

The TclJava extension uses the Java Native Interface to dynamically load a JVM within a C program. The extension was compiled against JAVA 1.4.2.12.  TclBlend is shipped with an embedded JVM which is loaded into the Tcl runtime on execution of the "package require java" statement.  Tcl scripts access the java class libraries using JACL(Java Command language) syntax.  Connectivity to remote java applications or services is possible using the appropriate third party java class drivers.  See the examples for more details.

Notes

There are no non core packages included with the TclBlend distro however packages like Expect, Tcllib etc can be copied over from an existing Tcl installation.  Just put them in the lib directory.

e.g copy to C:\tclBlend140Binary\TclBlend\lib

TclBlend can be installed across machines by simply copying the TclBlend/* directory structure to the target machine. 

Install Instructions.

### Strictly BETA.  Use at your own risk

1.    Unzip the binary to your installation directory.

Unzip to C:\tclBlend140Binary\TclBlend

2.    Test.

cd C:\tclBlend140Binary\TclBlend\bin\jtclsh.exe

% package require java
1.4.0

% java::import java.net.InetAddress

% puts "My IP Address is: [ [ java::call InetAddress getLocalHost ] getHostAddress ] "
My IP Address is: 123.4.5.6.7

## Run a script with embedded JVM.
