[tcljava-user] (no subject)

[Dan D. <dda...@ya...>]

Hi,

I am wondering why I need to "preserve" a TclList that I don't return to TCL, nor need/use after the function returns.

I am trying to return just one 
sub-list from a list of sub-lists.   If I have just a list 
of normal TclObjects I can return one item without a problem.   What is wrong with this:
 
public void cmdProc(Interp interp, 
TclObject argv[]) throws TclException
  {
    TclObject list = 
TclList.newInstance();
 
    //Create the first 
sublist
    TclObject list1 = 
TclList.newInstance();
    TclList.append(interp, list1, 
TclString.newInstance("1.1"));
    TclList.append(interp, list1, 
TclString.newInstance("1.2"));
 
    //Create the second 
sublist
    TclObject list2 = 
TclList.newInstance();
    TclList.append(interp, list2, 
TclString.newInstance("2.1"));
    TclList.append(interp, list2, 
TclString.newInstance("2.2"));
 
    //Add to main 
list
    TclList.append(interp, list, 
list1);
    TclList.append(interp, list1, 
list2);
   

    //list.preserve();   

 
    //return just the second sublist 
list
    
interp.setResult(TclList.index(interp, list, 0));
  }
 
When I run it (without the preserve()), I get 
this:
% 
ls_test
alloc: invalid block: 009B3DF0: f8 0 
0
 
This application has requested the 
Runtime to terminate it in an unusual way.
Please contact the application's 
support team for more information.

When I run a similar situation in my 
production code I get the error from JRE side, SIGSEGV on Linux and 
ACCESS_VIOLATION on Windows:
 
#
# An unexpected error has been 
detected by HotSpot Virtual Machine:
#

[tcljava-user] [ANNOUNCE] Aejaks 1.1

[Tom P. <tpo...@ny...>]

Aejaks 1.1 is now available.

http://aejaks.sf.net

This is primarily a bug-fix release.  The following issues
have been fixed:

    * Fixed Janino so that empty directories reported by Java's
        "java.ext.dirs" property don't cause a NPE in Janino.
        This fix allows Hyde and MrPersister to function in Java 1.6,
        which reports non-existent directories as the ext paths.
    * Fixed 'update' and 'updatePrepared' methods in MrPersister
        objects PersistenceManager and JdbcDao.
    * Remove old hydecache.tcl and hyde compile directories on
        startup.
    * Force run.sh to output Jetty stdout to the current tty.

AEJAKS: http://aejaks.sf.net

ABOUT:
Aejaks combines the server-side Ajax windowing system Echo2 with the powerful
simplicity of the Tcl langauge.  The result is a rich development environment
in which to develop Ajax-based web applications, often with much less code to 
write.  

Building a Rich Internet Application (RIA) usually means having to write 
your application in a variety of languages and markup: HTML, CSS, and 
Javascript for the browser, plus some backend language (PHP, Java, Tcl, etc.)
With Aejaks, you only need a single language: Tcl.  Aejaks applications 
resemble desktop Tcl/Tk applications.  Aejaks uses a Tk-inspired object 
interface to create and interact with widgets. 

Classic "Hello world" in Aejaks:

    Button .hello -text "Hello world" -command {. exitApp /index.html}
    Pack .hello

The first line creates a Button widget named '.hello' and defines a command 
to be run when the button is pressed (exit the application and tell the 
browser to load the index.html page.)  The second line makes the Button widget
visibile in the browser window.  That's all you need!

[tcljava-user] How does java interact with tcl?

[mallick c. <mal...@ya...>]

Hi ,
We have rewritten the tcl.lang.Shell to our need , so it works for us. The in/out streams are by default STDIN and STDOUT which does not solve our requirement , so we have written a simple client (reads/writes) in socket . the stdin and stdout is replaced with socket input stream and output stream.

hope this helps
Mallick

Hello dear ,



First at all, I'm not sure my question is proper or not to this topic. But,
I'm considering I should use Tcljava. Because I ask to here. 



I'm doing a project. In this project I'm making simple java program which
can interact with "tclsh". Java program is designed originally without
tclblend and jacl. In my idea, java can call the "tclsh" by using
'ProcessBuilder' class. It then gets input/error/ouput-streams of tclsh. If
I handle these three-stream, I may be able to handle tclsh through
java-program.(sample source code is attached below) This is my idea but, it
doesn't work. I think I couldn't get these streams. Anyway while
processbuilder are handling tclsh, tclsh process is working on system. 



I guess tclsh, I guess this is a kind of shell, uses own shell, so java
cannot intercept IO streams of it. 



How do you think of this problem?



Is there any solution? or

If do I use the TclBlend, can I obtain way to solve this problem?

If you have any experience or comment, please let me know. 



I'm working with:

Tcl version is ActiveTcl 8.4.

I'm using java sdk 6

And I tried test based on windows and linux both.



Thank you.

Best regards

[tcljava-user] Regex in Jacl 1.4 - Bug?

[Patrick F. <fin...@gm...>]

Is the regex implementation in Jacl the same as Tcl?


In tcl.


% set exp {sibJmsQueue\..+\.name\s+(.+)}
sibJmsQueue\..+\.name\s+(.+)

% set i "sibJmsQueue.ValidationQueue.name ValidationQueue"
sibJmsQueue.ValidationQueue.name ValidationQueue

% regexp $exp $i a b
1

In Jacl 1.4.

wsadmin>set exp {sibJmsQueue\..+\.name\s+(.+)}
sibJmsQueue\..+\.name\s+(.+)

wsadmin>set i "sibJmsQueue.ValidationQueue.name ValidationQueue"
sibJmsQueue.ValidationQueue.name ValidationQueue

[tcljava-user] Getting the data back from ByteArrayOutputStream.toByteArray

[BEASLEY, J. S <SBE...@sc...>]

Hello,

I am using a ByteArrayOutputStream object to read PDF data into, from a call to the iText library.  Everything is working out with tcl/Java and the library except this....  I perform a toByteArray on my ByteArrayOutputStream object, and it Creates a newly allocated byte array.  I do something like:

set j_byteArray [$memory_stream toByteArray] ; # memory_stream is my ByteArrayOutputStream object

This returns a good object handle from Blend.  How do I get the Byte Array Data from the Java object to a locale tcl variable in my code?  I can get it as a String like: set pdf_data [$memory_stream toString]  but the binary data in the pdf gets clobbered on the encoding conversion (I assume).  As of now, I have it working by Hex encoding the result of [$memory_stream toByteArray] in some Java code and calling and doing a [binary format] on the tcl side.  I would like a more direct way and save some processing time if I could.
 
Thanks

I am not sure what the cause of this could be. The following two 
commands would pass the exact same string argument:

sendToTcs 0 "set o \[new_Overlay__Orientation\]"

sendToTcs 0 {set o [new_Overlay__Orientation]}

Humm, I don't think this is a problem with the Java class you created. 
Most every problem people run into
is related to the CLASSPATH, this is likely one too. Could you try 
setting the CLASSPATH with the
platform separator char, in Windows this is a \ between directory 
elements. You can do that by putting
a [file nativename $path] call around your file join call.

hope that helps

[tcljava-user] Error lines and errorInfo in jacl

[Jared H. <ho...@mo...>]

So I see the open bug about reporting error line numbers in jacl.  How
do people work around this right now?  I also see the $errorInfo
variable being set in jacl, which would be useful if the error line
numbers could be trusted.  Unfortunately, any backslash newline
continuations earlier in the file cause the line number here to be
reported incorrectly (because these are parsed out before the error line
is calculated).  It seems to me that instead of parsing out the
backslash-newlines they should be treated as a different type of token
that is ignored for most purposes except for computing line numbers.
I'm not fully versed enough in jacl to do the code changes yet, but does
anyone have any thoughts on this issue?  Maybe I should send this to the
tcljava-dev mailing list.

Subject: problem with bracket translation "[ ]"
 

we are using a jacl/swank combination, but are having problems with the following:

sendToTcs 0 "set o \[new_Overlay__Orientation\]"

sendToTcs is a proc that takes 2 arguments. Now I want to send "[new_Overlay__Orientation]" exactly.. I do not want a any command evaluation. I tried two \ and that doesn't work either. I also tried:

sendToTcs 0 "set o {[new_Overlay__Orientation]}"

and that doesn't work either.

We are running Jacl 1.4

[tcljava-user] Fatal Error in Wish

[Rory M. <ro...@gm...>]

Iam trying to get TclBlend to open a simple java class.
The java code is as follows:

package p;
public class c
{

    public c(String s)
    {
        contents = s;
    }
    public String toString()
    {
        return contents;
    }
    public String contents = "default value";

}

and the tcl code is:

set env(CLASSPATH) [file join H: TCL_TEST myJar add newJAR.jar]
puts $env(CLASSPATH)
file exists $env(CLASSPATH)
package require java
set x [java::new p.c]

After i run the "set x [java::new p.c]" i get a Fatal Error:

Fatal Error in Wish
JavaCmdProc : Interp.callCommand() raised an Exception

"set x [java::new p.c "Hello world"]" throws the same error

Do you have any solution for this or any other way I can load this simple
java class?

[tcljava-user] New Jacl/Tcl Blend 1.4.1 release is online!

[Mo D. <mo...@mo...>]

This message is to announce the new 1.4.1 release of Jacl and
Tcl Blend.  These releases are the result of efforts by Mo DeJong
and the Jacl and Tcl Blend user community.

The 1.4.1 release of Jacl and Tcl Blend are available for
downloading at the following URL:

    http://sourceforge.net/project/showfiles.php?group_id=13005

The 1.4.1 release is considered stable and is now ready for evaluation
in production environments. This release is well tested and should be
bug free.

What's New in the 1.4.1 Release?
----------------------------------

Jacl 1.4.1 includes a new compiler named TJC (Tcl to Java Compiler).
A Tcl proc compiled with TJC will execute from 10 to 30 times faster.
TJC supports both a batch compile mode and a runtime compilation mode.
Jacl's expression engine has also been significantly optimized.

Itcl has been ported to Jacl, a user need only execute
"package require Itcl" to load Itcl commands into a Jacl shell.

Class loading has been completely overhauled for both Jacl and
Tcl Blend. The class loader delagation model is now used for
all class loading. Support for inner classes has also been
improved in the java package commands.

The java package now includes a new java::for command. This
command provides a mapping to Java's enhanced for loop statement
and provides a simplified way to loop over the elements of a
Collection or array object. See the documentation for usage examples.

A new binary release of Tcl Blend is now provided for Win32 systems.
This binary release includes compiled versions of Tcl/Tk, Tcl Blend, and
a full JDK 1.4.

See the included documentation for more information about new
features in this release.

What is Jacl?
----------------

Jacl is a 100% Java implementation of Tcl 8. This allows Tcl to run
in more environments and also brings the power of scripting to Java
developers. Jacl implements almost all the features available in
the C version of Tcl and is well tested.

What is Tcl Blend?
------------------------

Tcl Blend is a Tcl Extension that allows a developer access to the
Java VM from the Tcl interpreter. A developer can script Java
code from Tcl or write new Tcl extensions in Java instead of C/C++.
A developer can also load both Tcl and Tcl Blend into an existing
Java JVM. Tcl Blend is known to work on Solaris, Windows 95/NT/XP,
IRIX, and Linux. Other systems have not been tested but it should
be easy to port Tcl Blend to any system that supports dynamic
loading and the Java JNI interface.

For additional information:
---------------------------------

The primary website for Tcl/Java related information is:

    http://tcljava.sourceforge.net/

The README file included in the Jacl and Tcl Blend releases
includes lots or additional information including how
to sign up for the tcljava mailing lists.

Obviously it would be more efficient code, but it would force the changes on 
everyone, and you couldn't selectively upgrade. 

What I'm interested in is starting jaclsh and then source a compatibility 
file, then start my application. I've done this for lsearch.

So new question: how is file path normalization handled in jacl?

Compatibility needs to be implemented with changes to the Java code of 
the Tcl commands in Jacl.

[tcljava-user] Jacl compat procs for Tcl 8.4

[Tom J. <to...@rm...>]

Hi,

Has anyone produced a set of replacement procs so that scripts written in Tcl 
8.4 can run under Jacl?

I wrote a quick replacement for lsearch to add in the -all and -inline 
options, but then I found that I needed [file normalize].

Otherwise, are there a list of workarounds for this situation? 

Thanks,

tom jackson

It means that TclBlend was not initialized properly, but that should not 
happen. What exactly did you do? How did you
start the application? Did you build from source, if so does running 
'make test' work after a build? Can you run a simple
Tcl Blend example on your system?

Hi i had faced similar problems with this.TCL blend is using java JDK 1.2(check
in this folder) you will have to use the same jdk and jre for writing your
own codes

Hope this helps.
