[tcljava-user] Assertion failed: tsdPtr->initialized

[Chongkai J. <cho...@gm...>]

Hi there,

I'm trying to incorporate snmp4j into tcl by tcl blend. I wrote a Java class
and used Tcl blend commands to access it in Tcl, but I got the following
failures,

Assertion failed: tsdPtr->initialized, file
c:/TclBlendSrc/tcljava/src/native/javaCmd.c, line 359

This application has requested the Runtime to terminate it in an unusual
way.
Please contact the application's support team for more information.

Anyone could tell me what could have gone wrong? Is it possibly related to
thread safety? snmp4j sends a request and waits for response, but I'm not
sure if it does that in another thread.

Thanks.

This should be possible, the trick is that a constructor to the inner
class
has an implicit argument of the outer class.  I coded up a simple
exmaple, see
if you can apply it to your classes:


// ////////////////////////////////////////////////////////////////
// foo/Bar.java
package foo;

public class Bar {

    private String s;
    public Bar(String s) {
        this.s = s;
    }

    public String getS() {
        return "Bar s: " + s;
    }

    public class InnerBar {
        public InnerBar() {}

        public void printIt() {
            System.out.println("my Bar = " + getS());
        }
    }

}
// end foo/Bar.java
// ////////////////////////////////////////////////////////////////


$ javac foo/Bar.java

$ jaclsh
% package require java
1.4.1
% set B [java::new foo.Bar bing]
java0x1
% $B getS
Bar s: bing

{{foo.Bar$InnerBar} foo.Bar}
% set IB [java::new foo.Bar.InnerBar $B]

my Bar = Bar s: bing

[tcljava-user] Real "inner class" construction

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

In Jacl 1.4.0 Is there any way to instantiate a true "inner class" in
jacl as is described in:

http://java.sun.com/docs/books/tutorial/java/javaOO/summarynested.html

 

I see how to instantiate a static nested class:

set myNewStaticNestedObject [java::call OuterClass.NestedClass
$constructorArg1]

 

but I don't see the jacl equivalent to

OuterClass.InnerClass innerObject = outerObject.new InnerClass();

 

I guess I could make my inner class static nested and pass in the outer
class as an argument, but that gets messy in the java.

 

Thanks,

Jared

My understanding is that you are running telnetserver.jar as one
process. Then, you want to connect to it using a telnet client and
then automate the connection using expect. Right?

In C-based expect, when you run the command 'spawn telnet' it runs the
system's telnet client. Since the process was started by tcl, it has
control of child process's stdin and stdout.  The process connects via
tcp and handles all the weird telnet protocol stuff that goes on.
Expect uses the stdin and stdout to do its fancy expect/send
statements. Example of running:

> package require expect
> spawn /usr/bin/telnet hostname
> expect "login: "

In expect4j, to be as platform independent as possible, the spawn
command runs jakarta's commons-net library to connect via telnet. The
library simulates as much as possible, so you can the above command
just fine. The example found in the wiki
(http://code.google.com/p/expect4j/wiki/Installation) is:

> package require java
> java::load expect4j.ExpectEmulation
> package require expect
>
> spawn telnet 192.168.0.1
> expect "login: "
> send "root\r"
> expect "Password:"
> send "supersecret\r"
> expect "root@router:~# "

Your email pushed to be document some of this stuff. So I think you'll
find the example matches your initial email pretty closely.  Further
instructions pertaining to classpath can be found in the wiki too. If
you have any problems. I'd love to hear them.

If anyone knows how I can avoid the "java::load
expect4j.ExpectEmulation", when running from tcl.lang.Shell, I'd love
to know how. I've previously orchestrated the Intrep from my java
program, and had it load my class before running some a tcl scipt.
This way I can take c-based expect scripts and run them seamlessly.

[<ven...@wi...>]

Hi,
 
Thanks for all your inputs.
 
Shibu, You got it right. I want to talk to a java based telnet client.
The question that I had was how do I spawn the telnet process.
 
>From your reply, I understand that I have to invoke the java based client outside my tcl script and just use Expect from my tcl script to talk to it. Correct me If I'm wrong.
IMO, spawn command is what creates a connection to the process so that it is accessible for other Expect commands. So, If I run the telnet client outside my tcl script, how does it work other Expect commands.
 
 
 
Best Regards,
Venu Gopal V

If this is the case, you dont have to use TclBlend for this purpose.

Hi,

I have a telnet client application written in java.

The telnet application which is written in java is generally invoked from my Windows PC as below:
java -jar telnetserver.jar <portnumber of the server>

I want to interact with this telnet client in a tcl script using Expect.
I read some articles informing that Tclblend allows me to interact with java application from a Tcl script.
But I couldn't find exact information about how Expect can be used along with java application inside a Tcl script.

Please let me know how can I accomplish this task.

The below snippet is what I'm thinking of using to perform this task.
Please correct me incase I miss something.

++++++++++++++++++++++++++++++
package require Expect
package require Java

#Spawn a telnet session to the telnet server running on the target device
spawn java -jar telnetserver.jar <port number where Telnet server is listening>

expect "*in:"
send "<username>\r"
expect "*Password:"
send "<password>\r"

#Put a expression which you expect at the command prompt
# For example:
# A prompt like "[anil@Testers anil]$" requires
# expect "*anil]$ "
expect "<expression which we expect at the command prompt><space>"
++++++++++++++++++++++++++++++++++

Thanks In Advance,
Venu Gopal V

TclBlend launches it's own Jvm and can act as a java client to a remote java
application only if Jvm interprocess communication is available i.e. where an
application running on the remote Jvm is configured to listen on a specific
port.  In your case it seems that the application "telnetserver.jar" runs in
a remote Jvm launched by the " java -jar telnetserver.jar" command and
listens for telnet connections.  Just use expect as the telnet client and
spawn a connection to the remote java telnet server from Tcl Blend.  

package require Expect

spawn telnet $host


On the other hand if you want to manipulate "telnetserver.jar" then it needs a
programming api or a jmx management interface.

TclBlend launches it's own Jvm and can act as a java client to a remote java 
application only if Jvm interprocess communication is available i.e. where an 
application running on the remote Jvm is configured to listen on a specific 
port.  In your case it seems that the application "telnetserver.jar" runs in 
a remote Jvm launched by the " java -jar telnetserver.jar" command and 
listens for telnet connections.  Just use expect as the telnet client and 
spawn a connection to the remote java telnet server from Tcl Blend.   

package require Expect

spawn telnet $host 


On the other hand if you want to manipulate "telnetserver.jar" then it needs a 
programming api or a jmx management interface.

There is already a port of Expect for Jacl, see the message from

[tcljava-user] A question involving expect,java and tcl

[<ven...@wi...>]

Hi,
 
I have a telnet client application written in java.
 
The telnet application which is written in java is generally invoked from my Windows PC as below:
java -jar telnetserver.jar <portnumber of the server>
 
I want to interact with this telnet client in a tcl script using Expect.
I read some articles informing that Tclblend allows me to interact with java application from a Tcl script.
But I couldn't find exact information about how Expect can be used along with java application inside a Tcl script.
 
Please let me know how can I accomplish this task.
 
The below snippet is what I'm thinking of using to perform this task.
Please correct me incase I miss something.
 
++++++++++++++++++++++++++++++
package require Expect
package require Java
 
#Spawn a telnet session to the telnet server running on the target device
spawn java -jar telnetserver.jar <port number where Telnet server is listening>
 
expect "*in:"
send "<username>\r"
expect "*Password:"
send "<password>\r"
 
#Put a expression which you expect at the command prompt
# For example:
# A prompt like "[anil@Testers anil]$" requires
# expect "*anil]$ " 
expect "<expression which we expect at the command prompt><space>"

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
visible in the browser window.  That's all you need!

Hi Justin

Thanks for posting this note, I did not know there was a useful expect 
implementation out there
for Jacl. BTW, if you are looking for a home for the project, I really 
have no problem with adding
your expect implementation to the standard Jacl distro. Jacl already has 
Itcl bundled with it.
There are some issues that would need to be ironed out (license, regexp 
impl, and so on) but it should work,
if you are interested.

Re: [tcljava-user] Expect support

[Justin R. <ju...@ha...>]

In the Java space you have a few options for ssh/telnet scripting. The
cleanest implementation I've seen is enchanter (1).  While expectj (2)
is more compliant with actual expect library. I learned this while
investigating a expect solution for tcljava, and I also found that my
best option was to just write one myself which supports not only
expect in java but also the bindings needed for tcljava. The library
is called expect4j:

http://code.google.com/p/expect4j/

expect4j is aimed at supporting the functionality of the C-based
expect library, started by Don Libes, in java and tcljava.  The
library is written in java and uses a bootstrap class called
ExpectEmulation of load the relevant bindings into a tcljava Intrep.
The most important tcl functions have been implement, e.g. expect,
send, spawn. A full list of supported functions and global variables
are commented in ExpectEmulation.java.  I've successfully ported a
100K tcl script based on expect to tcljava, without any changes, by
just using expect4j.

One of the major limitations is that only ssh and telnet are supported
by the spawn command. This was done to limit interactions with
Runtime.exec(), and to keep the library completely in the java space.
This avoids the need for process control, forking, and PTYs.  On the
otherhand, the Expect4j class can be used for automating any
InputStream/OutputStream or Socket.  One of the unit tests shows how
to automate the "cmd /c net statistics Workstation" command on
Windows. For support of ssh/telnet, Jsch is used for ssh and
commons-net is used for telnet. The expect command can also match
against many different regexps/strings, unlike the other expect-like
libraries. ORO is used for the pattern matching.

The library is commented and unit tests are used to keep the library
in check is expect's original behavior. BUT there is little
documentation. For me, expect4j saved the day. If anyone is interested
in using this library I'd be happy to walk you through it. I'll use
that as motivation for writing the documentation.

Hi Chet

There is zero chance of expect working in Jacl. It depends on low level 
IO stuff that Java just
does not support. You could use expect in Tcl Blend though.

Re: [tcljava-user] Expect support

[D. J. H. <dha...@mi...>]

You definitely would not be able to use the full power of expect from
jacl, since that extension does some fairly low-level plumbing with Unix
PTY's, forking, and process control.

For telnet, you may be able to make socket connections and use a
simplified version of expect -- I think I remember seeing some examples
on the http://wiki.tcl.tk site.  SSH would be harder because you would
need to either write your own channel implementation using a pure-Java
ssh implementation (like jsch) or do your own tricks with Runtime.exec
and piped Input/Output streams and threads.

Hope this helps,

[tcljava-user] Expect support

[Chet V. <che...@gm...>]

Hi

Sorry if this is a newbie question but I was wondering if there's
support for Expect scripts. i.e can I run an expect script using the
Jacl interpreter ? We use expect primarily for network admin tasks
like login into devices/term servers via telnet/ssh and run commands.
Any useful pointers would be appreciated.

Thanks in advance,

Both Jacl 1.3.3 and Jacl 1.4.0 support the same expr commands, so the

good    morning all,

i'm trying to port an    existing application that uses tcl to generate code to a java based    application.

i have done the same using    jacl. one of the old tcl scripts uses a math function "max" and when the old    script is called from jacl i get the error : TCL.ERROR : unknown math function    "max"

any pointers on how to use    math function "max", please let me know

Re: [tcljava-user] TCL.ERROR : unknown math function "max"

[Martin L. <mar...@gm...>]

Hi,
 
it's relatively easy to tell, where the error's coming from ... in tcl 8.5
there are new expr operators like "min(value1,value2,...,valueN)" and
"max(value1,value2,...,valueN).
So your jacl distribution, your java generating application uses, is not of
this version 8.5.
 
Best regards,
 
Martin

Subject: [tcljava-user] TCL.ERROR : unknown math function "max"


good morning all,

i'm trying to port an existing application that uses tcl to generate code to
a java based application.

i have done the same using jacl. one of the old tcl scripts uses a math
function "max" and when the old script is called from jacl i get the error :
TCL.ERROR : unknown math function "max"

any pointers on how to use math function "max", please let me know

going, going, ... gone.



going, going, ... gone.
