[ANN] GroovyServ 0.10 released

[Yasuharu Nakano]

Hi,

We are pleased to announce about the release of GroovyServ 0.10.

Please inform us anything about GroovyServ.

[Changelogs]

New Features:
- [Client] -v option can also display the GroovyServ's version.
- [Network] Supported --allow-from option at groovyserver(sh). If
'localhost' is resolved except to loopback address in your
environment, you can use --allow-from option with groovyserver(sh). In
future, I want to support that groovyclient could access a
groovyserver at remote host in security. This is the first step.

Bug Fixes:
- Fixed 39: Processing of Groovy cmd line args is inconsistent
- https://github.com/kobo/groovyserv/issues/39
- Fixed 40: "System.env[name]" cannot access environment variables
at client side
- https://github.com/kobo/groovyserv/issues/40
- Fixed 41: ruby client cannot invoke groovyserver automatically
in windows 7
- https://github.com/kobo/groovyserv/issues/41
- And other small fixes and improvements are included.

So.. curious.. for a LONG TIME.. (i'm on OSX Lion at the moment)..

if I do ./groovyclient nd hit return… it just hangs on:

Starting.

i.e.:
rs:bin me$ ./groovyclient
Invoking server: './groovyserver' -p 1961
Groovy home directory: /opt/groovy
Groovy command path: /opt/groovy/bin/groovy (found at GROOVY_HOME)
GroovyServ home directory: /opt/groovyserv-0.10
GroovyServ work directory: /Users/rstudner/.groovy/groovyserv
Original classpath: (none)
GroovyServ default classpath: /opt/groovyserv-0.10/lib/*
Starting.

Any ideas why this is the case?

Best,
Roger

[Yasuharu Nakano]

hmm... the binary for mac is built on OSX SnowLepard. it might be the cause.
can you try to build it from source by yourself?

2012年3月30日19:31 Roger Studner <rstu...@gmail.com>:

[Yasuharu Nakano]

please try the follows:

$ groovyserver -v

if it failed, see ~/.groovy/groovyserv/groovyserver-1961.log.
if it succeeded, then try:

$ groovyclient -v
$ groovyserver -k
$ groovyclient -v

what's happened?
if they failed too, see ~/.groovy/groovyserv/groovyserver-1961.log.

And that is where it sits (this also has been true for many versions.. even if I bulid from source)

Hi Roger,

ok, I see. I saw the error message "Cannot cast object
'groovy.lang.Reference@11742dfe" before.
https://github.com/kobo/groovyserv/issues/38
Sorry, groovyserv requires groovy1.8.5+ now. I forgot to fix the
documentation about the requirement. I'll do it soon.

Could you upgrade groovy version?

regards,
yasuharu

That was it! thanks man (and i'm having success using the snow leopard binary on lion if that is good to know). I have the lion compiled version ready just in case hah, but haven't had to switch yet!

Best,
Roger

[Yasuharu Nakano]

thank you for very rapid and nice feedback, Roger!

Well.. it is you, not I, that provide this awesome piece of work to the community. So I just want to make sure I help out.. no one can expect people to make sure these things are perfect for all versions of groovy/all operating systems etc… on their own

(that being said, I run it on windows, osx and linux hah)

Roger

[Yasuharu Nakano]

I'm encouraged to hear you say that. As you say, a native application
is very difficult for me because it's very sensitive for environment.
so users' feedback is very helpful for me. thanks a lot.

Hello NAKANO san, I've installed the latest GroovyServe on my FreeBSD box a while back and it works very well. I use it for running mail rewriting utilities/filters called by procmail. Those are short running jobs that need to start frequently on a new set of data. Without GroovyServ (or something like Nailgun for Java) I could not have used java/groovy for this. Really pleased with your solution.

A question. Is there an API that would allow me to call methods of my classes loaded into GroovyServe from another JVM, i.e. from a servlet in an application server? I know I can always exec a groovy script from my servlet but a java|groovyclient API call would be quite convenient.

Thank you

Now, there isn't. but it's a interesting idea. groovyclient and
groovyserver just communicates by text base protocol on TCP. So it
might be realizable easily. actually, there are a similar code in
DirectAccessIT.groovy.

Ok, I've stocked the idea into my backlog:
- remote-accessible groovyserver
- [New!] groovyclient API using with java/groovy

Cheers,
