something goes wrong. Unfortunatly I do not understand the code well enough to

Hi!

I'm trying to build tclBlend1.3.2 with tcl 8.4.12 and thread2.6.2

./configure --with-tcl=../tcl8.4.12 --with-thread=../thread2.6.2/

[tcljava-user] A new Tcl to Java compiler for Xmas

[Mo D. <md...@un...>]

Ho Ho Ho!

Tis the season for giving and because Jacl users have been
very good this year, the gift of a shiny new compiler is
now available via the tcljava CVS. The compiler is
named TJC, which stands for Tcl to Java Compiler.
The TJC compiler accepts Tcl source code as input and
compiles Tcl procs into executable Java code stored in a
Jar file. The compiler is accessed via a startup script
named tjc.

The TJC compiler is ready for evaluation by early adopters
looking for significant performance improvements for
Jacl scripts. Currently, scripts can be compiled ahead
of time but there is no support for compilation of
Tcl procs at runtime.

A simple example showing how to use the TJC compiler
is appended to this email. Many thanks got to AMD,
New Iron Systems, and One Moon Scientific for funding
this project.

cheers
Mo DeJong



SIMPLE TJC EXAMPLE:

In the following example, a TJC module containing a single
Tcl script file and a single compiled proc will be created
and loaded into the Jacl shell. This example makes use of
the tjc executable and the TJC::package command.

In this example, the Tcl source file used as input to the
TJC compiler is defined as follows:

$ cat simple.tcl
proc simple {} {
    return "SIMPLE"
}

The user will now need to create a TJC module file for the
TJC package. The name of the module file will be simple.tjc.
The name of the Java package will also be "simple", this is the
same package name that will later be passed to the TJC::package
command. The SOURCE and INIT_SOURCE declarations will list
only the simple.tcl file.

$ cat simple.tjc
PACKAGE simple

SOURCE simple.tcl
INIT_SOURCE simple.tcl

OPTIONS

Assuming that the tjc executable is already on the PATH, the TJC
compiler is invoke via:

$ tjc simple.tjc

If no error is generated, then nothing is printed and the files
simple.jar and simplesrc.jar are created in the current directory.

Note that simple.jar contains both the compiled version of the
proc simple and the script simple.tcl.

This TJC package can be loaded into a Jacl shell by adding
simple.jar to the CLASSPATH and invoking Jacl.

$ export CLASSPATH=${CLASSPATH}:`pwd`/simple.jar
$ java tcl.lang.Shell

At the Jacl shell prompt the following Tcl commands would be entered
to load the TJC package and init the simple package.

% package require TJC
1.0
% TJC::package simple
% simple
SIMPLE


The example above shows how a compiled version of the Tcl proc
named "simple" is loaded into the Jacl shell and executed.
The results returned by the compiled "simple" command are
the same as would be returned by the Tcl version of the command.

Re: [tcljava-user] Class not found after successful class import.]

[Patrick F. <pfi...@oz...>]

Thanks for the tip Mo.  The class is loaded but I now get an SQL error.

"set c [ java::field ClientDriver class ]"

This loads the class but the subsequent call to "DriverManager" generates 
a "no suitable driver sql error".


I am trying to emulate the JDBC load database driver using the Class 
forName technique explained here:
http://www.jguru.com/faq/view.jsp?EID=11164

Class.forName("org.apache.derby.jdbc.EmbeddedDriver");
Connection conn = DriverManager.getConnection( "jdbc:derby:mynewDB", p);

In JACL the method call fails with a class not found error.

"java::call Class forName org.apache.derby.jdbc.ClientDriver"
"set ConnectionI [ java::call DriverManager getConnection $url ]"

I had another look at the Class API and added the tcl class loader as 
the loader
parameter.

set c [ java::field ClientDriver class ]
set classLoader [ $c getClassLoader ]

In this case the classloader is " tcl.lang.TclClassLoader" because the 
jar file containing "ClientDriver" is specified using the tcl_classpath 
variable.

"java::call Class forName org.apache.derby.jdbc.ClientDriver true 
$classLoader"

Class.forName now loads ClientDriver but I still get 
"java.sql.SQLException: No suitable driver" on the call to DriveManager.

It does look like a classloader issue. The work around is to add the
Derby database jar files to the system classpath.

set CLASSPATH=%CLASSPATH%;C:\IBM\Cloudscape_10.1\lib\derby.jar
set CLASSPATH=%CLASSPATH%;C:\IBM\Cloudscape_10.1\lib\derbyclient.jar
set CLASSPATH=%CLASSPATH%;C:\IBM\Cloudscape_10.1\lib\derbynet.jar
set CLASSPATH=%CLASSPATH%;C:\IBM\Cloudscape_10.1\lib\derbytools.jar

c:\tclblendSun\bin\jtclsh.bat 
C:\CvsSandbox\FITZROY\FM\SCRIPTS\TCL\JACL\cloudscape\createCloudScapeDB.tcl

When the foloowng statements are executed...................

set c [ java::field ClientDriver class ]
set  classLoader [ $c getClassLoader ] 


the classloader for ClientDriver is now 
"sun.misc.Launcher$AppClassLoader" and the call to DriveManager succeeds.

So it would seem that the process that the database driver class uses to 
register the driver with the DriveManager only works if it's loaded with 
the same class loader as the DriveManager.

"The specified driver must implement the Driver interface. A class 
initializer (static code block) within the OracleDriver class registers 
the driver with the DriverManager". 
 
Regards.

Patrick.

No. You could take a look at some of the example code in
unix/custom.c and unix/custom2.c to see how you might
compile your own .exe for Tcl Blend with hard coded paths.
There are makefile rules to build both of these executables.

You can't just call class.forName()  like that. Depending on how the classloader
is implemented in the JVM, it may not work. If you want to get a ref to a
java.lang.Class for a specific named class, use the class field of the object.

[tcljava-user] TclBlend compile - bat file dependency.

The TclBlend configure script generates a bat file which denotes the

Re: [tcljava-user] Class not found after successful class import.

[<PFi...@hb...>]

I can get around this problem by putting the appropriate jar file on the 
system class path.  But it;s strange that the "java::import" finds "
EmbeddedDriver" but the "java::call" fails unless the class is on the 
system class path. 

The  tcl classpath is set as follows. 

lappend x C:\\IBM\\Cloudscape_10.1\\lib\\derby.jar 
lappend x C:\\IBM\\Cloudscape_10.1\\lib\\derbyclient.jar 
lappend x C:\\IBM\\Cloudscape_10.1\\lib\\derbynet.jar 
lappend x C:\\IBM\\Cloudscape_10.1\\lib\\derbytools.jar 

set env(TCL_CLASSPATH) $x

I tried various forward and back slash combinations.  None of then worked. 


I also tried modifying the classpath variable within the script but that 
did not work either. 

set CLASSPATHList [ split [ lindex [ array get env CLASSPATH ] 1 ] ";" ]
lappend CLASSPATHList $x 
set env(CLASSPATH) $CLASSPATHList

puts "\nNew CLASSPATH is...............\n"

foreach i [ split [ lindex [ array get env CLASSPATH ] 1 ] ";" ] {
    puts [ format "%-5s %-50s" " " $i ] 
}

Has anyone else had issues like this on Windows XP.  I really don't want 
to have to put all the required jar files on the system class path.

[tcljava-user] IBM JACL and TCL_CLASSPATH.

[<PFi...@hb...>]

The IBM JACL implementation does not pick up the TCL_CLASSPATH variable.

For example; adding the Derby java database jars.

lappend x C:/IBM/Cloudscape_10.1/lib/derby.jar
lappend x C:/IBM/Cloudscape_10.1/lib/derbyclient.jar
lappend x C:/IBM/Cloudscape_10.1/lib/derbynet.jar
lappend x C:/IBM/Cloudscape_10.1/lib/derbytools.jar

set env(TCL_CLASSPATH) $x

The jacl command "java::import org.apache.derby.jdbc.EmbeddedDriver"

generates 

WASX7017E: Exception received while running file 
"c:\scripts\websphere\jacl\getJ
VMINFO.tcl"; exception information: com.ibm.bsf.BSFException: error while 
eval'i
ng Jacl expression: can not import class 
"org.apache.derby.jdbc.EmbeddedDriver",
 it does not exist
 
The work around is to add the required jar files to the WAS_CLASSPATH in 
the WSADMIN bat file. 

....................
....................
:runcmd

set WAS_CLASSPATH=C:\IBM\Cloudscape_10.1\lib\derby.jar;%WAS_CLASSPATH%

"%JAVA_HOME%\bin\java" %javaoption% %CONSOLE_ENCODING% %DEBUG% 
"%CLIENTSOAP%" "%CLIENTSAS%" 
"-Dcom.ibm.ws.scripting.wsadminprops=%WSADMIN_PROPERTIES%" 
-Dcom.ibm.ws.management.standalone=true 
"-Duser.install.root=%USER_INSTALL_ROOT%" "-Dwas.install.root=%WAS_HOME%" 
"-Dwas.repository.root=%CONFIG_ROOT%" "-Dserver.root=%WAS_HOME%" 
"-Dlocal.cell=%WAS_CELL%" "-Dlocal.node=%WAS_NODE%" 
"-Dcom.ibm.itp.location=%WAS_HOME%\bin" "-classpath" 
"%WAS_CLASSPATH%;%WAS_HOME%\lib\jython.jar" "-Dws.ext.dirs=%WAS_EXT_DIRS%" 
com.ibm.ws.bootstrap.WSLauncher com.ibm.ws.scripting.WasxShell %*
...............
...............

This allows use of the Derby database for WAS performance data logging.

[tcljava-user] java::cast with array signature.

[<PFi...@hb...>]

JAVA Code.
**************
"MBeanLevelSpec[] mlss = (MBeanLevelSpec[])ac.invoke(perfMbean, 
"getInstrumentationLevel", params, signatures);"

The results of "ac.invoke" are casted to MBeanLevelSpec[]" 

JACL Code.
**************
"set il [ $AdminClientI invoke $perfMbean "getInstrumentationLevel" 
$parramsArray $signaturesArray ]" 
"set mBeanLevelSpec [ java::cast {MBeanLevelSpec[]} $il ]"

The cast generates: 

unknown class "MBeanLevelSpec"
    while executing
"java::cast {MBeanLevelSpec[]} $il "

Changed code to: "set mBeanLevelSpec [ java::cast MBeanLevelSpec $il ]"

This generates:

could not cast from com.ibm.websphere.pmi.stat.MBeanLevelSpec[] to 
com.ibm.websp
here.pmi.stat.MBeanLevelSpec

It seems the usage of "[]" in the cast statement invalidates the signature 
name.

What is the proper usage of java::cast if the signature is an array? 


Regards.

Re: [tcljava-user] Converting java array to a tcl list for use with lsearch.

[<PFi...@hb...>]

Yeah you are right.  It's possible to iterate and cast in one line.


   set serverSet   [ $AdminClientI queryNames $ObjectNameI $nullI ]
   set serverMbean [ java::cast ObjectName [ [ $serverSet iterator ] next 
] ]

Regards.

Re: [tcljava-user] Java Keyword - "this".

[<PFi...@hb...>]

Tried that but got:

"error in procedure java::call: expected object of type 
javax.management.Notifica
tionListener but got "java0x3" (com.ibm.websphere.management.AdminClient)"

AdminClient is created using AdminClientFactory "set AdminClientI [ 
java::call AdminClientFactory createAdminClient $PropertiesI ]"

The notification listener is created using "AdminClientI 
addNotificationListener $nodeAgentBean this $nullI $nullI"

The addNotificationListener method takes a NotificationListener object 
argument which is denoted by the "this" keyword in the statement above.  I 
suppose this acts recursively. 
public void addNotificationListener(javax.management.ObjectName name,
                                    javax.management.NotificationListener 
listener,
                                    javax.management.NotificationFilter 
filter,
                                    java.lang.Object handback)
                             throws 
javax.management.InstanceNotFoundException,
                                    ConnectorException

NotificationListener is an interface with no static methods so I cannot 
create it outside of an addNotificationListener method. 

If you are interested the javadoc for the IBM WebSphere Application 
ServerTM, Release 5
API Specification is at:

http://publib.boulder.ibm.com/infocenter/wasinfo/v5r0/index.jsp?topic=/com.ibm.websphere.base.doc/info/aes/javadoc/ae/index.html

The javadoc for NotificationListener is: 

javax.management
Interface NotificationListener

Method Summary
 void   handleNotification(Notification notification, java.lang.Object 
handback)
          Invoked when a JMX notification occurs.
 

Method Detail
handleNotification

public void handleNotification(Notification notification,
                               java.lang.Object handback)

    Invoked when a JMX notification occurs. The implementation of this 
method should return as soon as possible, to avoid blocking its 
notification broadcaster.

    Parameters:
        notification - The notification.
        handback - An opaque object which helps the listener to associate 
information regarding the MBean emitter. This object is passed to the 
MBean during the addListener call and resent, without modification, to the 
listener. The MBean object should not use or modify the object.




Regards.

Patrick.

probably:

set tclList [list]
set arrayI    [ $serverSet toArray ]
foreach obj [$arrayI getrange] {
    lappend tclList $obj
    # or maybe: lappend tclList [$obj toString]
    # depending on what kind of objects are in your Set
}





instead of converting to an array, you could also just use the
iterator, it's a little less messy:

set tclList [list]
set set iteratorI [ $serverSet iterator ]
while {[$iteratorI hasNext]} {
    lappend tclList [$iteratorI next]
    # may have to cast your object from the iterator, or toString as above,
    # again depending on what objects you have in your Set.
    # lappend tclList [java::cast xxx.yyy.YourObject [$iteratorI next]]
    # lappend tclList [[$iteratorI next] toString]
}



(I *love* the 'java' package in Jacl!)

Wouldn't you just just $AdminClientI, as in:

    $AdminClientI addNotificationListener $nodeAgent $AdminClientI $nullI $null

[tcljava-user] Converting java array to a tcl list for use with lsearch.

[<PFi...@hb...>]

The java.util.Set interface does not have an array signature.  I converted 
the Set collection to an array using the Set.toArray method and accessed 
the array with the javaArrayObjcommand set.

Is there an easy way of converting a java array to a tcl array that can be 
used with lsearch. 

For example:

   set iteratorI [ $serverSet iterator ] 
   set arrayI    [ $serverSet toArray ] 

   puts "\n serverSet array length [ $arrayI length ] \n"

   *** set tclList [ convert $arrayI ]

Then use regular tcl commands.

   lsearch $tclArray xxx

   foreach i $tclArray { puts $i } 



Regards.
