Re: [tcljava-user] jacl140, which .jars are required/optional

[Bruce J. <nm...@ma...>]

jacl.jar and tcljava.jar are the only necessary files.

oro.jar was a regular expression package, a replacement for which is  
included in the above files.

itcl.jar is an optional object oriented language to sit on top of  Tcl.

tjc.jar is the new Tcl to Java compiler.  It includes code that  
allows you to compile your Tcl procedures to Java and then to Java  
byte codes.  We're using this a lot right now and it is  easy to use  
(after a little learning curve) and definitely can speed your code up  
a lot.

There should be docs for all these in the jacl1.4.0 distribution.

[tcljava-user] jacl140, which .jars are required/optional

[Bill D. <bil...@xi...>]

Greetings,

We're trying to upgrade from an old version of jacl, where we linked 
against jacl.jar and oro.jar.

The new package has:
* tcljava.jar
* jacl.jar
* itcl.jar
* tjc.jar

Do I need to include all these, or are some optional?
If some are optional what additional functionality does each provide.

Thanks,
Bill

Re: [tcljava-user] Using Tcl Blend with NASA WorldWind Java SDK

[<Dan...@dl...>]

Hi again,

first of all, thank you for your quick reply!

I haven't yet been able to figure out why I'm getting this =
java.lang.ExceptionInInitializerError, but here's what I get when =
running jtclsh with the -verbose:class option.

There seems to be something wrong with the =
gov.nasa.worldwind.ThreadedTaskService class, right? Or is it when =
trying to load the next class that the error occurs? In this case, how =
can I find out which class it's trying to load after it has successfully =
loaded the ThreadedTaskService class?

Also, running jtclsh with the -verbose:jni option yields this result:

This is a generic Java error that indicates an exception was raised=20

Try setting the  Tcl Classpath  variable inside the tcl script.

E.G for MQ.

# build tcl classpath

append x $drive/IBM/WebSphereMQ/Java/lib/com.ibm.mq.jar\;
append x $drive/IBM/WebSphereMQ/Tools/Java/base\;
append x $drive/IBM/WebSphereMQ/Java/lib/com.ibm.mqjms.jar\;
append x $drive/IBM/WebSphereMQ/Tools/Java/jms\;
append x $drive/IBM/WebSphereMQ/Java/lib/com.ibm.mqbind.jar\;

set env(TCL_CLASSPATH) $x

puts "\nTCL_CLASSPATH = [ array get env TCL_CLASSPATH ]\n"

See class loading page of manual.

http://tcljava.sourceforge.net/docs/TclJava/ClassLoading.html

Also check the system classpath supplied to the script.

Something like:

set classPath [ split [ lindex [ array get env CLASSPATH ] 1 ] { ; } ]

foreach i $classPath {

    if { $i != {} } {

      puts $i

    }

}

[tcljava-user] regarding java objects

[Mrinal K. <mr...@gm...>]

Hi,
I have a web application which runs expect scripts on remote machines using
tclBlend. Now i want to use the same thing to push java objects into the
data base

this is how i invoke the jtclsh shell from my web application

Runtime rt = Runtime.getRuntime();
                Process proc = rt.exec("cmd /c C:\\TclBlend\\bin\\jtclsh.exe
C:\\ScriptFiles\\script"+ ""+ID
                + ConstantsFile.SCRIPT_FILE_EXTENSION);

and the contents of the script file that i am using is given below

#!C:\TclBlend\bin\jtclsh --
package require java
package require Expect
set session null
spawn telnet afads 23
set something [java::new chars.rulewizard.GenerateFactObject "mrinal123"]
puts $something


and the "GenerateFactObject" class is just a dummy class i want to
instantiate for testing

/**
 *
 * @author Baba
 */
public class GenerateFactObject {
    public static FactObject fact;
    /** Creates a new instance of GenerateFactObject */
    public GenerateFactObject(String strName) {
        System.out.println("working = " + strName);
    }
}


now when i try to run that script it gives me "unknown class
"GenerateFactObject""
i know there can be a problem with the classpath but i changed it but the
error doesnt go.

the next thing i tried is that i copied the GenerateFactObject.class file
into the C:\TclBlend\bin dir(where jtclsh is present)

Again when i tried running (java::new GeneratFactObject "Mrinal") ,it still
gives me the same error (unknown class "GenerateFactObject").
In short, if I want to instantiate custom java objects , what should be
location for there class files?
can anyone please guide me on this.

Regards,
Mrinal

[tcljava-user] Using Tcl Blend with NASA WorldWind Java SDK

[<Dan...@dl...>]

Hi,
=20
I'm trying to use Tcl Blend together with the NASA WorldWind Java (WWJ) =
SDK, i.e. creating WWJ objects from Tcl, accessing their fields, =
invoking their methods, etc. [WWJ uses JOGL for the visualization of a =
virtual globe (analogous to Google Earth)]
=20
I have been able to create JOGL objects from Tcl, such as GLCanvas, =
GLJPanel, and some WWJ objects such as IconLayer, =
EarthNASAPlaceNameLayer, etc. but I have not been able to create some =
WWJ objects, in particular WorldWindowGLCanvas and WorldWindowGLJPanel.

Specifically, I get the following error message when trying to create a =
WorldWindowGLCanvas object from jtclsh:
=20
 medina@onyx:/opt/tclblend/bin> ./jtclsh
 % package require java

If I really need to load .dll files, is there any solutions?

Thanks. 
I have a tcl script. And in the code there is "load xxx.dll". The requirement now is to retrive data from the tcl script in a java program. So I cannot use Tclblend, cause it is used to write java code in Tcl, right?
 
I cannot modify the tcl script. In this situation, what should I do? Is there any solution?

Jacl does not support the load command since it only works C dlls. You 
could use Tcl Blend though.

[tcljava-user] invalid command name "load" when eval tcl in java

[wang d. <ru...@ya...>]

Hi,
    Now I am writing a java plugin in eclipse to try to get data from a Tcl API. 
    My code is as following:
   Interp interp;
   interp = new Interp();  
   try{
      interp.eval("package require XXXX");     
      interp.eval("::XXXX::YYYY");
    
    // TclObject[] result = TclList.getElements(interp, interp.getResult());
   
   }
   catch(TclException ex){
    ..................................
     } 
   finally{
   interp.dispose();
   }
  The error is "invalid command name "load"", 
  there is "load [file join $dir zz.dll zz" in the tcl script of XXXX, the path of dll file is right. Why the dll cannot be loaded? 

And I also notice that [info sharedlibextension] is jar, not dll. The auto_path is "resource:lang/tcl/library", info library=E:\eclipse-SDK-3.3M6-win32\eclipse\plugins\org.eclipse.equinox.launcher_1.0.0.v20070319.jar. I think maybe the enviornment is not set properply. But how can I change the environment? Could you please give me some idea? I really do not know. Any help will be greatly appreciated.

Another question is when interp.eval(::xxxx::yyyy), there is error "cannot find package" or "invalid command name  ::xxxx::yyyy.  Does Jacl of Tclblend support package? Just want to confirm. I think this problem maybe is the same as the first one.

BTW all the script run successfully in Tcl console. 

Thanks again

Best regards,
Joy

[tcljava-user] derby Tcl Cookbook

[Jim M. <thi...@ya...>]

Hi Patrick -
thanks for the sample code for using apache derby(cloudscape) at the activestate site.
it is very cool :-) 
i wasn't 100% sure i could use derby last night.  i hadnt had a chance
to read the links yet.
i just checked and i can use possibly use hibernate with derby to.
derby and hibernate usage will be the first things i test.

if i can use hibernate, i already have an idea for my first project.
now i sit around waiting for my books for a week or so.

thanks again,
jim

ok.  i will use the precompiled version patrick talks about below.

i tested the tcl - c++ tool before i think it is called swig.
i think i will like this much better.

This is not correct, a JVM is needed on the deployment machine. In 
general, Java is an interpreted
runtime. The hotspot compiler will speed up execution time but a JVM is 
still needed at runtime to
execute Java code. The Tcl Blend module makes it easy to create both a 
Tcl interpreter and a Java
interpreter in the same process and then let each interpreter talk to 
the other.

Re: [tcljava-user] running tcl w/java

[Jim M. <thi...@ya...>]

had some experience on that one.
i had a eclipse app i made with derby client.
then i switched it to embedded.
fooled around making minor modifications
coding and left a connection open.
had to reboot the machine.
not the best way to debug!
all that was missing was the win 95
blue screen gpf message.
once it is ready it sure is nice to lose 
the 35mb though for deployment.

Re: [tcljava-user] running java code

[Jim M. <thi...@ya...>]

hi Patrick - 
i just went to the first link and saw you were using oracle
with a JDBC driver.  I use windows O/S.
i remember there was oratcl.
i am hoping there is oratcl is embedded like
apache derby can be or i might be able
to use apache derby.  but my first thoughts  on
that is it might be easier to use  a jdbc db  that tcl
already has bindings for. not sure yet.
 what i am going to investigate
right now is the requirements for using groovy
and how that relates to this. i just checked that.
1.4 or greater is ok.  i am used to 1.5 but i could
probably pick up a used 1.4 manual.
this sounds really cool so far.
thanks for the great links and assistance,
jim

Re: [tcljava-user] running java code

[Jim M. <thi...@ya...>]

hi-
i thought about this after i took a break.  if it says it has an embedded
jvm. so that means to me that if on the development machine i create
the byte code then the embedded jvm can turn the byte code into
machine code and then execute it.

so it seems there is no jre needed on the deployment machine.

this seems cool as you could use groovy too.  i wonder if i could use a db
that works with groovy? i'll have to check into that.

please let me know if i got it right. 
thank you,

[tcljava-user] tcl bend - question re: running java code

[Jim M. <thi...@ya...>]

hi -
wikipedia says - 
TCLBLEND: call Java class libraries from the C runtime using JNI and an embedded JVM.

i think i read that java has to be compiled to bytecode before it can be interpreted.
once the java code is compiled does tclblend require the java runtime environment
present so a java method or object can be used from within tcl? in other words if i wanted to deploy a tcl app that used tclblend would i also need to deploy the jre?
i was hoping i could write code that made use of collections and call it from tcl
without having the jre needed for deployment. that would be a big feature.
some people dont want to download the entire jre before checking out my java app (and in this case tcl app).

thanks for shedding some light on this for me.
i usually dont know what makes something run behind the scenes.

You need to either tell the package system how to load a package named 
"Ixia" or just
declare the package as loaded after sourcing ethr.tcl.

You could do something like:

package ifneeded Ixia 1.0 {source c:/TCAS/cgi-bin/lib/ethr.tcl/ethr.tcl 
; package provide Ixia 1.0}

Take a look at the package command manual and you should be able to 
figure it out.
