User input from JConsole?

Hi, I've been trying to use your JConsole to create a simple command-line
interface. Every features is perfect, except that I still can't figure out
how to get the user input.

I tried using BufferedReader using getIn() as a parameter, but for some
reason the BufferedReader is blocked. I'm not familiar with neither
BufferReader or JConsole so I can't figure out how to fix the problem.

Can you help me fix this or give me an alternative?

Thank you

java.io.WriteAbortedException: writing aborted; java.io.NotSerializableException: bsh.CallStack

I have been receiving this error off and on for sometime now.

Using:
jdk 1.6, bsh_2.04b

The error is difficult to reproduce because it seems random.  If I run the
same script on the same data that caused the error it never seems to
reproduce it.
This is very problematic.

I see that there is an old bug related to serialization.
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4171142
Might this be related?

thanks for the help

String Strangeness

Using bsh-2.0b5 embedded in JMeter-2.5.1

Trying to do a simple string assignment in a test script (test.bsh):

String rawBCString = "288/SetEntryList/7/ITSPUAT9/Home Page2/\9";

And get the following...

<snip>

bsh % source("test.bsh");
// Error: // Uncaught Exception: Method Invocation
this.interpreter.source : at Line: 14 : in file:
/bsh/commands/source.bsh : this .interpreter .source ( filename , this
.caller .namespace )

Called from method: source : at Line: 1 : in file: <unknown file> :
source ( "test.bsh" )
Target exception: Sourced file: test.bsh Token Parsing Error: Lexical
error at line 1, column 63.  Encountered: "9" (57), after :
"\"288/SetEntryList/7/ITSPUAT9/Home Page2/\\": <at unknown location>

bsh %

<snip>

Anyone got any ideas what's going on here? I think it's something to
do with escape chars but having a "9" after a "\" doesn't seem like
anything odd to me. Looks like java is taking the raw string, escaping
all the "\" chars and then barfing on the result..

Executing Eclipse SaveAll command from beanshell

I have a beanshell script that is run inside Eclipse via Practically Macro. I need the script to run the File
-> SaveAll command, but I'm having problems getting a reference to the ICommandService that Eclipse
provides. 

The service locator generally uses PlatformUI which doesn't seem accessible inside beanscript. I've
also tried getSite() per the Eclipse Services help (http://tinyurl.com/c9o8a9g). It's unclear to me if
I will be able to access these inside a beanscript.

I end up getting the error "Typed variable declaration : Command not found: getSite()" or "Attempt to
resolve method: getWorkbench() on undefined variable or class name: PlatformUI"

Any pointers?

TIA,
J.D.

import org.eclipse.swt.custom.StyledText;

import org.eclipse.debug.ui.DebugUITools;
import org.eclipse.ui.commands.ICommandService;

		try
		{
			// Save all editors first
			ICommandService service = (ICommandService) getSite().getService(ICommandService.class);
			console.writeln("service is " + service.toString());

Reg. Non-English string literal in Java code

Hi,
I am using bean shell interpreter to execute Java code.
If any string literal in Java code has non-English characters
(say, Russian) then such characters becomes garbled when
the interpreter is executing the code.
Is there a way to support internationalization during
bean shell interpreter execution of Java code ?

Usage of bean shell interpreter
Interpreter interpreter = new Interpreter();
interpreter.eval(javaCode);

Content of javaCode
ArrayList aList = new ArrayList();
aList.add("<RussianCharsHere>");
aList.add("<RussianCharsHere>");

Any help is appreciated.

Thanks

Re: Loading .java Files

Ok you are using "eval".  The terminology ".java" confused me.
You are loading  a "beanshell" file  not a "java" file.  Although they are
often similar.

If you want to invoke a non-static method in a class you do it the same way
in beanshell as you do in java.
you need to instantiate the class to invoke the method.

    new Foo().bar()

I dont think you can do this with BSHMethod.invoke()
(You can with eval)

My prefered method of executing bsh from within java is to use the Interface
methods.
 e.g.
     (ICampaignScript) mInterpreter.getInterface(ICampaignScript.class);

then you can call bsh methods directly via the interface.

but again this only calls 'top level' methods.   To create classes and call
them you need to run eval() or to expose a top level method which calls
them.
I dont know of any way directly from the java API to do it.

Loading .java Files

Hi,

when I load a complete .java File, the global namespace has no methods:

public class Foo() {
  void bar() {
    //
  }
}

When I load this, the namespace has the method bar():

//public class Foo() {
  void bar() {
    //
  }
//}

Is this a bug or by design?

Thank you

Trivial question about initial script sourced automatically for every JConsole.

Hi everybody!

I've got a small probably trivial problem with beanshell
I'm trying to embed beanshell into my application by doing simple
bsh.Interpreter i = new bsh.Interpreter();
i.eval("desktop()");

what I'm trying to do is to source an initial file into the interpreter 
so that the stuff defined therein is available immediately in any shell 
created in the desktop, and it just does not work.

I've tried different things
1) before/after evaling desktop() in the code above I tried 
i.source("/pathto/boot.bsh");
2) modified makeWorkspace() command in the distribution so that
this.interpreter = new Interpreter( console );
+ this.interpreter.source("/pathto/boot.bsh");

the functions defined in /pathto/boot.bsh are simply not there.
However if i do source("/pathto/boot.bsh"); within the shell (in the 
desktop), everything is fine.

It's pretty annoying pasting this every time, I would appreciate if 
anyone would have a suggestion...

Thanks in advance!

Thread BLOCKED using BS in Multi threads

Hi all,

I am having an issue when running multiple BS at the same type in
different threads in the same JVM.

Almost all the treads are getting into BLOCKED state due to some
synchronized code in Class.forName.

As a result the time of operation is much longer.

I have noticed that it happens mainly when the scripts are using
"source" to load other scripts.

Each threads have his own engine.

Any suggestion ?

Thanks

Fred
