[tcljava-user] Jacl 1.4 - support for package require with "resource".

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

Just wondering if "package require" works with resource and libraries packed
in jar files.

e.g.  something like.

C:\Tcl\lib>jar -cvf tcllib1_9.jar tcllib1.9

set CLASSPATH=%CLASSPATH%;C:/Tcl/lib/tcllib1_9.jar

java -classpath %CLASSPATH% tcl.lang.Shell

% lappend auto_path resource:/tcllib1.9
resource:/tcl/lang/library resource:/proclib resource:/tcllib1.9
% package require term
can't find package term
% package require log
can't find package log

"resource" can load jarred libraries prepared with auto_mkindex.

Re: [tcljava-user] "source resource:/" - howto?

Jacl uses TCLLIBPATH, not TCL_LIBRARY to find packages.  Jacl's init.tcl
holds all of the clues:

    http://tcljava.cvs.sourceforge.net/tcljava/tcljava/src/jacl/tcl/lang/library/init.tcl?revision=1.7&view=markup


I routinely use a modified 'jaclsh' that allows me to include Tcl packages 
that I place either in my Jacl installation dir (ones that are Jacl only), or
specify other directories via an environment variable.  For example:

    $ export JACL_LIBRARY=/usr/lib/tcllib1.7
    $ jaclsh
    % # include my jacl based 'hyde' package
    % package require hyde
    1.3
    % # include log from tcllib
    % package require log
    1.2

TCLLIBPATH is not split on ":", you have to space-separate directory entries.

My Jacl installation :
    ls -CF /usr/local/lib/tcljava1.4.0
    hyde-1.3/  itclsrc.jar  jaclsrc.jar  janinosrc.jar  tcljava.jar     tjc.jar
    itcl.jar   jacl.jar     janino.jar   swank.jar      tcljavasrc.jar  tjcsrc.jar


The hyde-1.3 directory has a valid pkgIndex.tcl file:
    package ifneeded hyde 1.3 "source [file join $dir hyde.tcl]"

Note Tcllib1.7 has very few packages that require Tcl 8.0, I just
used that as an example.  Tcllib was installed from my Linux
package system.

Here is my 'jaclsh', a couple of notes first.
  - I copy swank.jar into my Jacl installation, and do
    'ln -s jaclsh wisk'.  That way, I can start Jacl or Swank
    from the same script, either by invoking 'jaclsh' or 'wisk'.
  - The following environment variables are recognized:
	JACL_FLAGS  - JVM memory & other options
	JACL_LIBRARY - Tcl libraries to include
	JACL_PROPS  - other JVM options, I use this for any "-Dxxxx=yyy"
	JACL_MAIN - if using a custom shell
	JAVA_HOME - which ever JVM I want to use

Package require is supported under Jacl. It is likely you are not using 
the auto_path variable in the way it should, you can add
a path with a "resource:/" prefix to the auto_path and it should be 
searched as expected.

This is not how TCL_LIBRARY should be used. In general, TCL_LIBRARY is 
where Tcl/Jacl
find its own scripts. You should not use this for your application scripts.

[tcljava-user] resource with auto_path - possbile slight bug with name spaces.

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

There seems to be a slight bug with auto_path and/or resouce.  Procs with
name spaces are not found initially.
e.g .

Top level bat file.

setlocal

set tclScript=
C:\home\patrick\eclipse\WASAdminSBV\WSAdmin\WAS5.1\tcl\sendJavaMail.tcl
set javaCmd="C:\Program Files\Java\j2re1.4.2_05\bin\java"

set CLASSPATH=%CLASSPATH%;C:/downloads/TCL/jacl/tcljava.jar
set CLASSPATH=%CLASSPATH%;C:/downloads/TCL/jacl/jacl.jar
:: ### proclib jar holds scripts.
set
CLASSPATH=%CLASSPATH%;C:/home/patrick/eclipse/WASAdminSBV/WSAdmin/WAS5.1/JACL/proclib.jar
set CLASSPATH=%CLASSPATH%;C:/downloads/java/javamail-1_4/javamail-1.4
/lib/smtp.jar
set CLASSPATH=%CLASSPATH%;C:/downloads/java/javamail-1_4/javamail-1.4
/lib/mailapi.jar
set CLASSPATH=%CLASSPATH%;C:/downloads/java/activation.jar

%javaCmd% -classpath %CLASSPATH% tcl.lang.Shell %tclScript%

endlocal


Called tcl script.

=============================================================
#
# send mail using java mail library.

package require java

lappend auto_path resource:/proclib

puts "auto_path is [ set auto_path ]"

# putsLog proc
putsLog "test message"

# javaMail namespace.
javaMail::javaMail you...@yo... "test email" " body text"

==============================================================

If the putslog proc is left in jacl finds  javaMail::javaMail.  If the
putslog proc is commented out jacl fails to find javaMail::javaMail

sendJavaMail.cmd
invalid command name "javaMail::javaMail"

putsLog is defined like:

proc putsLog { a { channel stdout } } {

    global env

javaMail::javaMail is defined like:

namespace eval javaMail {

    proc javaMail { emailAddress subject body } {


Does the tcl unknown command work in jacl the same way as tcl or is there a
difference in the way the auto_index file is loaded?

The way I normally load the procedure library is;

1.  Set a java system variable using the D option.

export TCL_LIBRARY="TCL_LIBRARY=/directoryPath/JACL
java bla bla bla -D$TCL_LIBRARY

2.  Pick up the TCL_LIBRARY variable in the top level  jacl script.

set TCL_LIBRARY [ java::call System getProperty TCL_LIBRARY ]

3.  Call a "sourceProcs.tcl script.

source [ file join $TCL_LIBRARY sourceProcs.tcl ]

Every top level script gets the $TCL_LIBRARY variable and calls
sourceProcs.tcl which does a recursive search under the TCL_LIBRARY
directory, locates any directory called proclib and sources each procedure
script in the proclib directory loading everything up into the namespace.

What I would really like to do is dynamically load the procedure scripts as
required in a "package require" type scenario.  But "package require" is not
supported under jacl so I thought about using auto_mkindex which seems to be
supported under jacl.  It seems to work with both directories and jar
files.  Great!

1.    Directory.
    *******
wsadmin>auto_mkindex proclib

then ...................

set TCL_LIBRARY="directoryPath/proclib"

Call jacl with the java -D option

java bla bla bla "-DTCL_LIBRARY=%TCL_LIBRARY%"

Within the script......

set TCL_LIBRARY [ java::call System getProperty TCL_LIBRARY ]

lappend auto_path $TCL_LIBRARY

Now procedures are loaded dynamically without the need for an explicit
source command.

javaMail::javaMail  xxxxx  xxxxx xxxxx

2.    Jar File.
    ******
wsadmin>auto_mkindex proclib

jar -cvf proclib

set CLASSPATH=%CLASSPATH%;directorypath/proclib.jar

java bla bla bla -classpath %CLASSPATH%

lappend auto_path resource:/proclib

javaMail::javaMail  xxxxx  xxxxx xxxxx

The most simple example would go like so:

% source resource:/tcl/lang/library/parray.tcl

This uses the Java API to load a resource named 
"/tcl/lang/library/parray.tcl"

This is loaded from jacl.jar via the system classloader:

$ jar -tvf jacl.jar | grep parray
   885 Thu Apr 19 13:34:28 PDT 2007 tcl/lang/library/parray.tcl

To add your own scripts that use source, just jar up your .tcl files and 
place the jar on the CLASSPATH.

[tcljava-user] "source resource:/" - howto?

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

Can someone post an example or point to an example of how to use "source
resource:/".  I want to put my JACL scripts in a jar file and put the jar
file on the class path.

Thanks.

Thanks Mo.  I have no 'nagging' issues, Jacl is 1.4.x stable and predictable.
My latest code uses the most recent Jacl from CVS.

There are two items that I would ask you to consider.  

1. IncrTcl 'cget' patch.  Eckhard Lemann submitted a patch to
  IncrTcl/C that provides an extra optional parameter when defining 
  variables, to allow code to be executed when a variable is
  fetched ($obj cget -var).  I'd like to have that in Jacl IncrTcl,
  and lobby Jeff Hobbs to put it in IncrTcl/C.  

  In Aejaks, I provide public variables that access getXxx/setXxx methods.
  'setXxx' is no problem of course, but I had to implement a series of
  traces on each object's variables to enable 'getXxx' behavior.  Pretty
  ugly, probably a lot slower, but it does work.  
  
  http://elehmann.wordpress.com/tcltk/itcl-cget-code/
  http://sourceforge.net/tracker/index.php?func=detail&aid=1362070&group_id=13244&atid=313244

2. My 'open resource:/' patch for Jacl.  I would like to be able to
  have an entire application bundled into a .war file.  Tcl code is no
  problem thanks to 'source resource:/'.  I'd like to be able to read
  other non-Tcl files in the .war just by using 'open'.

Very nice! I notice you are using the 1.4 version and the bundled IncrTcl.

If this MQ library includes native code, then you will need a version 
with native code compiled for
Solaris. Are you able to write a simple pure Java main class that loads 
this MQ library and opens
a connection? If that does not even work, there is no point in trying to 
get it to load into Tcl Blend.

On Unix systems, one should use ':' and ';' should be used on Windows 
systems. It is very lame that Sun did not
deal with this issue in the JDK, and left it to each application, but 
that is the way it is.

Re: [tcljava-user] NoClassDefFound

Actually, solved one problem - I found my default java.library.path from
looking through config.log.

The other one is still an issue, however also I have no mqjbnd02.so as the
ibm MQ jar comes from an old Windows kit. I can only find a dll. 

Perhaps I need to find a different set of MQ libraries with a Solaris .so
file ?

Sounds like you need to set "-Djava.library.path=<path to mqjbnd02.dll"
 
You can set the java options inside the tcl blend script using tclblend_init
before calling "package require java".

manual page - http://tcljava.sourceforge.net/docs/TclJava/JavaPackage.html
<http://tcljava.sourceforge.net/docs/TclJava/JavaPackage.html> 

e.g something like: 

lappend optList "-Djava.naming.provider.url\=$NAMING_PROVIDER "
lappend optList "-Djava.naming.factory.initial\=$NAMING_FACTORY"
lappend optList $CLIENTSOAP
lappend optList "-Dwas.install.root\=$WAS_HOME"
lappend optList "-Dws.ext.dirs\=$WAS_EXT_DIRS "
# set tracefile properties.
lappend optList "-DtraceSettingsFile\=TraceSettings.properties"

puts "\n java command line options list is:\n"

foreach x $optList {

    puts [ format "%-5s %-50s" " " $x ] 

}

set tclblend_init $optList  

# call java package 

package require java






Do you know which jar file on Solaris has this mqjbnd02 class ?

I have my LD_LIBRARY_PATH and PATH set to where the com.ibm.mq.jar file is.

Thanks for your help.

For Solaris have a look at these links.   Search for mqjbnd02.

On Windows...............

"The *java.lang.UnsatisfiedLinkError* is encountered when the environment
variable java.library.path is not set.

Sounds like you need to set "-Djava.library.path=<path to mqjbnd02.dll"

You can set the java options inside the tcl blend script using tclblend_init
before calling "package require java".
*
manual page - http://tcljava.sourceforge.net/docs/TclJava/JavaPackage.html
*
e.g something like:

*lappend optList "-Djava.naming.provider.url\=$NAMING_PROVIDER"
lappend optList "-Djava.naming.factory.initial\=$NAMING_FACTORY"
lappend optList $CLIENTSOAP
lappend optList "-Dwas.install.root\=$WAS_HOME"
lappend optList "-Dws.ext.dirs\=$WAS_EXT_DIRS"
# set tracefile properties.
lappend optList "-DtraceSettingsFile\=TraceSettings.properties"

puts "\n java command line options list is:\n"

foreach x $optList {

    puts [ format "%-5s %-50s" " " $x ]

}

set tclblend_init $optList

# call java package

package require java



*

Do you know which jar file on Solaris has this mqjbnd02 class ?

For Solaris have a look at these links.   Search for mqjbnd02.*

Re: [tcljava-user] NoClassDefFound

[Robinson, D. <Dav...@Co...>]

Patrick,

On Solaris 10 TCL_CLASSPATH doesn't seem to like more than one jar (or have
I got the separator wrong ?) :

append x /apps/fidessa/top/commerzbank/lib/com.ibm.mq.jar:
append x /apps/fidessa/top/commerzbank/lib/com.ibm.mq_websphere.jar

Result :
cannot import class "com.ibm.mq.MQC", it does not exist
    while executing
"java::import com.ibm.mq.MQC"
    (procedure "checkMQ" line 6)
    invoked from within
"checkMQ $QManager $CCSID $channel $hostname $queueName $port $traceFile
$msg"
    (file ".//MQEx.tcl" line 124)

While 

append x /apps/fidessa/top/commerzbank/lib/com.ibm.mq.jar

works OK.

Also I get this :

checkMQ 

java.lang.UnsatisfiedLinkError: no mqjbnd02 in java.library.path
    while executing
"java::new MQQueueManager 1"
    (procedure "checkMQ" line 14)
    invoked from within
"checkMQ $QManager $CCSID $channel $hostname $queueName $port $traceFile
$msg"
    (file ".//MQEx.tcl" line 124)

Do you know which jar file on Solaris has this mqjbnd02 class ?

I have my LD_LIBRARY_PATH and PATH set to where the com.ibm.mq.jar file is.

Thanks for your help.

David

Hi, I'm using tclblend for the first time. I have successfully compiled some
java classes that reference functions in an external MQSeries .jar file
which is in a non-standard directory. However, when I try to call the class
from jtclsh I get 

 

% package require java

Which path env var or tcl setting do I need to change to get the references
to get these objects visibility ?

Re: [tcljava-user] TclBlend - how to debug?

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

I just added the Derby jars to the system classpath.  I am debugging the
TclBlend scripts in Eclipse 3.2 using the DLTK plugin and since Eclipse does
not pick up system variables I thought I would have to set them inside the
IDE.  As it happens Blend picks up the system Classpath from inside Eclipse.

Trid your list approach plus............

foreach i [ glob -directory C:/db-derby-10.2.2.0/lib/ *.jar ] {

    append env(TCL_CLASSPATH) $i\;

}

I get ...............

cannot import class "org.apache.derby.drda.NetworkServerControl", it does
not exist

So TclBlend finds the class if the jars directory is specified but not if
the jar file is added explicitly to the TCL_CLASSPATH variable i.e 6 below.

The TclClassLoader seeks unresolved classes in these locations in the
following order:


   1. The cache of previously loaded classes

    2. The CLASSPATH list

    3. The pathList list, looking only in directories or jar files
   specified by pathList (available only for the java::load command)

    4. The pathList again, inspecting all jar files found in each
   directory (only for the java::load command)

    5. The env(TCL_CLASSPATH) list, looking only in directories or jar
   files specified by env(TCL_CLASSPATH)

    6. The env(TCL_CLASSPATH) again, inspecting all jar files found in
   each directory


The TCL_CLASSPATH variable works fine for all my MQ stuff.

You probably need to specifiy each jar file, not just
the directory.  

e.g.
set derbyLib {C:/db-derby-10.2.2.0/lib/derby.jar C:/db-derby-10.2.2.0/lib/derbyclient.jar ....etc...}

[tcljava-user] TclBlend - how to debug?

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

I get a Null point exception when I try to instanciate an imported class.
What's the best way to debug Blend?

Using TclBlend Windows binary.

C:\TclBlend\bin>jtclsh

% set derbyLib [ file join $env(DERBYHOME) lib ]
C:/db-derby-10.2.2.0/lib

% set env(TCL_CLASSPATH) $derbyLib
C:/db-derby-10.2.2.0/lib

% package require java
1.4.0

% java::import java.net.InetAddress

% java::import org.apache.derby.drda.NetworkServerControl

# display imported classes.
% java::import
org.apache.derby.drda.NetworkServerControl java.net.InetAddress

% java::new NetworkServerControl
java.lang.NullPointerException

The script works when started from a bat file with the jars are added to the
system classpath .


::set CLASSPATH=%CLASSPATH%;C:\db-derby-10.2.2.0\lib\derby.jar
::set CLASSPATH=%CLASSPATH%;C:\db-derby-10.2.2.0\lib\derbyclient.jar

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:

Tcl Blend should work find with JDK 1.5.

This is a generic Java error that indicates an exception was raised
while loading the class or invoking the
static init method for the class. You will have to look at the class in
question to find out why. If this package
uses native code then it could fail because it does not find needed DLL
on the PATH.

I hope that helps
Mo
