[tcljava-user] Installing TCL_Blend on a current activeState Active TCL 8.4.5.0

[Lawrence M. T. <law...@sw...>]

Hello,

I'm quite a newbie in TCL_Blend. I'm attempting to install TCL_Blend on 
my computer, as I can finally manage my java phidget toolkit within TCL.

I've seen that installation of tcl-Blend may require the TCL and thread 
build. Since I already have the activeState tcl 8.4.5.0 installed on my 
computer, do I still have to follow the steps listed in the readme file?

Thanks for any hints you might give me.

Best regards

Lawrence Michel

[tcljava-user] Problem: NoClassDefFoundError

[Soviet U. <sss...@gm...>]

 I've installed the tclBlend1.3.2, threads263, tcl8.5a4, tk8.5a4 using msys,
as was described in their README files. The installation seemed to be OK,
andnow in the folder "C:\msys\local\bin" I have tclsh85.exe and
wish85.exeexecutables and
jtclsh.bat. The TCL itself works fine, but I cannot load TclBlend. When run
jtclsh.bat and write in it "package require java", it sais:

% package require java
Exception in thread "main" java.lang.NoClassDefFoundError: tcl/lang/Interp
"XpUtils::iload -d C:/msys/local/lib/tcljava1.3.2 tclblend" failed:
 could not find class "tcl/lang/Interp".
Check your CLASSPATH settings.
Currently, the CLASSPATH environment variable is set to:
;c:/Program
Files/Java/jdk1.5.0_06/jre/lib/rt.jar;/lib/tcljava1.3.2/tcljava.jar
;/lib/tcljava1.3.2/tclblend.jar

What's wrong?
All the paths in the env variables in jtclsh.bat seem to be correct.

[tcljava-user] tcl.lang.CharPointer.<init>(CharPointer.java:88)

[Raul E. (wizardteam) <ra...@wi...>]

Hi again,

Now i m getting a little problem with the applet.  Again, the code is
simple, just a way to figure out how to work from now on with jacl:

----
import tcl.lang.*;
import java.awt.*;
import java.awt.event.*;
import java.applet.*;

public class mytest extends Applet {
    private Interp _interp;
    public void init () {
        try {
            _interp = new Interp();
            _interp.eval("clock seconds");
            TclObject result = _interp.getResult();
            System.out.println("And the result is: " + result.toString());
        } catch (Exception e) {
            System.out.println("mytest: init() " + e);
            e.printStackTrace();
        }
    }
}
----

And this is trowing me this error:

mytest: init() java.lang.NullPointerException
java.lang.NullPointerException
	at tcl.lang.CharPointer.<init>(CharPointer.java:88)
	at tcl.lang.Interp.eval(Interp.java:2220)
	at tcl.lang.Interp.evalResource(Interp.java:2777)
	at tcl.lang.Interp.<init>(Interp.java:429)
	at mytest.init(mytest.java:10)
	at sun.applet.AppletPanel.run(Unknown Source)
	at java.lang.Thread.run(Unknown Source)

By googling, i found an old version of jacl.jar and tcljava.jar, those works
without problem, but has not all functions in it (specially "clock").  The
thing is now with an applet, b'cause when i do an app, it compiles and runs
fine.

Is there something i m missing?

RE: [tcljava-user] re: tcl/lang/TclException error (Solved!)

[Raul E. (wizardteam) <ra...@wi...>]

I found the solution!

Its just a matter of adding codebase="." archive="tcljava.jar,jacl.jar" into
the html's <applet> tag.  Found that by googling after the hint i got from
Martti (thanks mate!).

Excellent!!

[jacl]# java -classpath ./jacl.jar:./tcljava.jar:. test

I see a dot can make the difference! hehe.  But now how can i apply the same
to an applet?  My goal its to include tcl commands into an applet.

[tcljava-user] tcl/lang/TclException error

[Raul E. (wizardteam) <ra...@wi...>]

Hi,

I am kinda new in java, and experienced in TCL, and I am trying to use TCL
commands into java, but i get this errors:

When i try to do a sample app, it compiles fine including tcljava.jar and
jacl.jar in the classpath,

but when running, even including both jars in the classpath, i get the
follow error:


# java test -classpath ./jacl.jar:./tcljava.jar

the code is simple:

  Interp interp = new Interp();

  } catch (TclException ex) {
  }
  System.out.println(resultado);
 }
}

Now, if i want to do an applet (a different code than the last one, but
based in it), things get worse and i get all this error:

The CVS version of Jacl has integrated tcltest support. All you need to
do to load tcltest via:

    package require tcltest

Hello All,

I'm curious to see whether anyone out there is using jacl or tclblend
with the tcltest package.  I've got a suite of several thousand
integration tests that is based on Tcl and Tcltest that I would like to
migrate.  The migration is mostly motivated by the test subject's
migration to a Java implementation.
=20
As far as I can tell there really hasn't been a mention of tcltest with
Tcl/Java on the mailing list for years so I decided to do a few
experiments.
My first test involved the latest jaclsh and the tcltest.tcl  package
from 8.4 ( I read about some issues of loading the requried packages
from a jar file) but this failed since jaclsh appeared to report itself
as Tcl 8.0.   Is this the latest Tcl version that jaclsh supports?
=20
=20
So this brings me to the question of whether there are any success
stories out there with jaclsh or tclBlend with tcltest?  If there are
I'd love to hear about them.

Ack - it works.
I have scattered several installations of Tclblend in several Tcl installations (ActiveTcl, Msys/Tcl, Tclkit...) and the .dll was loaded from the wrong location. The message is, that Tcl as well as JVM need to load the *same* dll at the same time.
To make it work with Tclkit, Tclblend has to be compiled and linked against stubs, of course. Then, tclblend.dll can not be wrapped, it has to be in the user's file system. So it is best to extract it from the deployed starkit to some location, extend env(PATH) to this location and make sure it is loaded from there rather than from the wrapped extension during "package re java". And - of course jre/bin and jre/bin/client must be on env(PATH).

Pretty cool, still no need for a Tcl installation on the user's machine :-)

tclblend.dll would not be that problematic, I could for sure find a way to bring it in the user's file system. Actually, I did not wrap it during my test - it was in my file system and the PATH extended to include it's base directory.
The problem is obviously the static build of Tcl in Tclkit. It seems that Jvm can not work with the running Tcl_Interp because it does not come from a shared library (tcl.dll). But I don't know that exactly...

A workaround would be to create an installer starpack that installs a minimalistic Tcl version, including tcl84.dll, tclsh.exe, tclblend.dll and the packages that are necessary to run starkits - and call it "tcl-java-bridge base installation". Hmm, that will do it for now...


Eckhard

BTW, thanks for the great work, Mo. It will ease the J2EE pain ;-)

I have not heard of anyone getting that working and I would be willing to bet
that it is going to be very tricky. Both Tcl and the JVM need to be able to find
tclblend.dll on the file system. Just getting Tcl to see the shared lib on the
Tcl virtual filesystem would not be enough. You would likely need to work some
magic to write tclblend.dll to a tmp dir somewhere and then load it at runtime
so that the JVM can find the native symbols.

Good Luck

[tcljava-user] tclblend with Tclkit

[Eckhard L. <ec...@we...>]

Hi,

I compiled and installed Tclblend on windows XP. It runs fine with ActiveTcl as well as an own MinGW built Tcl.

Now, it is important for me, that tclblend runs with Tclkit (deployment in our organization). First, I tried to "package re java" from Tclkit. I did this with the small test script appended below. The result was, that it crashed. Tclkit is built with threads enabled.

Then I recognized that TclJava is not build with -DUSE_TCL_STUBS and not linked against tclstub. I assume that this lead to the crash and changed the compile setup a little to build and link against tclstub.
Again, the installation went fine and the script ("package re java" being the most important line) runs fine with ActiveTcl and MinGW Tcl. But now, when I run it with tclkit, I got the following error:

#
# An unexpected error has been detected by HotSpot Virtual Machine:
#
#  EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x046748dd, pid=3032, tid=2968
#
# Java VM: Java HotSpot(TM) Client VM (1.5.0_06-b05 mixed mode, sharing)
# Problematic frame:
# C  [tclblend.dll+0x48dd]
#
# An error report file with more information is saved as hs_err_pid3032.log
#
# If you would like to submit a bug report, please visit:
#   http://java.sun.com/webapps/bugreport/crash.jsp
#

I recompiled tclblend with -DTCLBLEND_DEBUG, to see where the crash happens and was able to backtrack it at the line

local = (*env)->NewObject(env, jcache->Interp,
	    jcache->interpC, lvalue);

in Tclblend_Init(Tcl_Interp *interp). At a first glance, this call from the JNIEnv environment tries to set a Tcl_Interp as java object somehow. I assume that this is not possible because the interpreter is statically linked in Tclkit. :-(.

Is it possible somehow to get Tclblend working with Tclkits? How much work would that be, if possible at all?


Thanks in advance,
Eckhard

Check the docs for the java::load command.

Will, you need to pass the name of the class, not including the trailing
".class" bit at the end. For example, [java::load foo.bar.Baz] not
[java::load foo.bar.Baz.class].
I hope that was the cause of your problem, your post includes many many
lines of code, far to many to scan through. Postings should just include
a little snip of code that causes the problem.

RE: [tcljava-user] fileevent and sockets in jacl

[Rob R. <rr...@fu...>]

Mo,

I'd even be more aggressive and go straight to using JDK 1.5. There many
benefits to using 1.5 over 1.4 now that it might be worth considering the move
now. It seems with the 1.6 release coming out around the corner that 1.4 is
pretty dated now. But, yes I'd say that 1.4 should be the oldest JDK supported
(if there is a great demand for that.)

JMHO,

Rob

Each Jacl download comes with the file license.txt that gives the license terms.

Hello

OK, then I must wait until Jacl is ported to JDK 1.4.
Can you say me in witch time this would be done, half year or a year?

I agree too,
current jacl is stable enough to be freezed, and you could provide some
jacl-2.0 with some compatibility break (if you need it)
(adding swank or other library as oddon ?)

Maurice

P.S.
   I'm not currently using jacl in critical project, so my opinion
   should not be very important in your decision...
