Re: WebMacro Proof of concept...

[William KC Wong]

What about FreeMarker ? Has there been any development on this excellent
template system ? I know that John McNally has been the main contributor
to this engine. Will this template be supported (in Turbine) in future ?
Or am I missing something that all focus is now on WM ?

WebMacro Proof of concept...

[dave bryson]

In previous e-mails, its been mentioned that the User admin
inteface will be implemented using the new WebMacro service.
I'd also like to redo the scheduler interface using the new WM and
remove all the older WM stuff.
However, doing this has a couple ramifications to the Turbine setup.

For Turbine to work out of the box, default.page and the
default.sessionvalidator must be set in the TurbineResources
distibution file to the WebMacroSite service. 
Doing the above will probably push new users of Turbine
to use WebMacro and cause current users to reconfigure a few things
when updating to a newer version of Turbine.

IMO, this forces a change in direction for the Turbine
default presentation mechanism (from ECS to WebMacro).   

Is this a direction we want to move or should we look at a better way
to integrate the two out of the box? 

Either way involves configuration issues/decisions.

Is a vote in order?

that line of code is this:

Criteria criteria = new Criteria();

that shouldn't cause a problem unless for some reason that class can't be
found properly or something.

did you remove all your compiled classes and start fresh? a lot of stuff has

(sorry...i couldn't resist the stupid humor)

take a look at org.apache.turbine.util.webmacro.WebMacroLink

there is a $link object that is placed into the WMContext for you to use.

Yes.  This is exactly what I have in mind.  I've also thought about possibly

Yes.  Take a look at the WebMacroSite Service. It allows you to use the
Turbine framework to organize your WebMacro pages and Screens. Start
with the README.txt in the examples/webmacro directory.  Then try out
the simple example and look at screens/Testlink.  Let me know if you
have any questions, 'll be happy to help you get started with it.

You can do this with the WebMacro Service and Turbine.  See Testlink in
the modules/screens directory AND the associated template in
examples/webmacro directory.  It's not much, but it's a start.

I apologize for this...we are still working on this area of Turbine quite
heavily and have just now started finalizing stuff enough for others to use
it. Next step...documentation and examples...

Both at the same time. :-)

If you look at the example stuff that Dave just recently checked in, things
will become clear.

I'm working on re-doing the whole admin interface section of Turbine to
follow this exact same model. Other than the basic example stuff that is
checked into cvs, we don't have any public applications yet. I can say
though that what I have seen and done so far kicks some serious booty. :-)
Everything is very nicely abstracted out.

Migration Path

[Nissim]

Hi everyone,

I have a web application which I've written using Servlets and JSSI, and
I want to port it to Turbine, and WebMacro.  I don't understand the
integration of these two frameworks, and I'm trying to figure out how to
go about the migration.

Here are my Questions:

1) should I first convert it to use WM, without turbine, and then move
it into the turbine framework, or the other way around?

2) If you're using turbine and WM is it recommended to use turbine
navigations to put the same stuff on the top and bottom of each page,
and not WM #parse?

3) I really want to separate the application so that there isn't any
html generation in the java code, and minimal code in the templates.  Is
there an example application which works this way within turbine/WM ?

Thanks.

Great idea! Something like this would have saved me a lot of time the last

Turbine Developers Kit

[dave bryson]

I've been thinking about how to help folks become productive - faster
with Turbine.   I really think Turbine is a great Framework and I'd
like to see it catch on even more than it has. But, I believe in order
for that to happen, you've got to really make things easy for
developers ( we're a lazy bunch). 

So, with that in mind, here's what I've been thinking about  
adding on top of the application generation utility from the wish
list.

Turbine Developer's Kit (TDK)

Goal:  Ease development with and installation/setup of Turbine. 

How:  Bundle Turbine with a configured copy of Tomcat and instantdb. 
This would allow user to quickly setup and try out Turbine with out
having to do the Servlet engine setup, DB setup etc  This also
provides an ideal enviroment for the programmer on the go.  This and a
JDK is all that's needed to develop/prototype apps on a laptop/PC. 

Besides having the Servlet engine and DB for development, you'd also
have the application generation utility. It would help you: 
1. Setup  the directory structure for a new application. 
2. Create the build.xml for compiling the new app.  
3. Configure Tomcat to test out the application. 
4. Maybe add a deployment option to generate any needed files when you
move your app to production.   

Is this worth the effort?

Would anyone find this useful?

I'm using the IBM JDK1.1.8 on Linux.  After moving the ant.jar and
xml.jar as I mentioned in the previous e-mail I had no problems.  I
don't believe it has anything to do with JDK version, my hunch (and
it's just that)  is that it might be something with xml.jar and xerces.

I seem to have forgotten something, I thought Turbine would work with jsdk

if you are using tomcat, you shouldn't download ANY servlet.jar's or jsdk
2.0or have them in your classpath.

tomcat is a servlet engine that implements the latest jsdk. it comes with
its own copy of the interfaces that are needed for the jsdk. you don't need
to download them from sun.

our previous instructions were for Apache JServ which we assumed you were
using because (i personally) didn't see you post messages about your
configuration. in the future, you should post clear messages about
configuration and version information so that we don't go into circles like
that again.

you *should* make sure that you are using the latest version of tomcat
though which is 3.1.

Re:java.lang.ExceptionInInitializerError:java.lang.NullPointerException

[Nissim]

I once had the same error messages, and it was because I was using just
the turbine DB connection pool, and I hadn't set the properties file...

Those exceptions get thrown when static code in a class throws an
exception.  In my case it was some static {... } code in the DBFactory
class, which had an uncaught exceptionwhen the TurbineResources was not
initialized with a filename.  In your case it's probably that one of the
methods called in that class VisitorRolePeer in the top couple of lines 

static blahblah = SomeClass.someStaticMethod(blah, blah);

is throwing an exception.

What I really meant to say was...

   correct the obvious problem before tackling the subtle problem,

and we all know that Turbine will never run right
with servlet.jar.

I leave it up to others who know what's going on with the
infinite redirect to help find a resolution to that problem.

Re: Install problem - Infinite redirect detected...

[John McNally]

Why do you say using servlet.jar instead of jsdk.jar is causing the infinite
redirect problem?  I am seeing this problem on my home machine alot (it
generally happens when I reload a page after recompiling something, but I am
able to reload it again and move on.)  I am pretty sure I do not have
servlet.jar anywhere on my computer.

BTW, I guess since I am getting this error so often I should attempt to
figure out the cause, but I usually only have a couple hours to work at
night and am trying to make some progress on a project.  If it just wasn't
so easy to ignore it.

Try the following:

Make sure you select "Java Servlet Development Kit 2.0" at the

I guess your entry was NOT removed. If you enter something to the FAQ,
an administrator has to review it first and - if considered well - 
release it to the public. Try to login with the same ID when you created
the new entry and see if it is there (with yellow backgroud, which means
unreleased...)

Have fun!

Re:java.lang.ExceptionInInitializerError:java.lang.NullPointerException

[Bernie Hoeneisen]

Thanks, but this cannot be the problem; the file
TurbineResources.properties exists, has read permission for
everyone (-rw-r--r--). Furthermore in zone.properties there is a line:
servlet.Turbine.initArgs=properties=/home/faq/proj/turbine/conf/TurbineResources
.properties
(where the file is located).
Before the exception is thrown some information is read out of
TurbineResources.properties and used witout any problem.

Any other hints? 

It seems that this problem has to do with the recent changes in the
Turbine Visitor/Role/Permission-Peers area.

Any help is appreciated.

Do you know where I might go to get the 2.0 version of jsdk.jar ?

yes. it has everything to do with it.
you don't want the current version of the library.
please ensure that jsdk.jar (2.0, not 2.1) is ahead of
servlet.jar in the classpath.

Turbine FAQ

[Stephen Adkins]

Hi,

I have a suggestion for the FAQ.
I think that we could improve its usefulness with the
addition of Troubleshooting sections.
This would map concrete error messages which appear
in the log files to causes.  This would help people
locate their problem more easily and find all of the
causes which might have been behind the error.

I had created such a section in the FAQ for

   Troubleshooting - Building Turbine

and added an entry for the error which I encountered
over the weekend

   java.lang.IncompatibleClassChangeError: Unimplemented interface method

Then I entered the cause of the error and the fix
(which Dave Bryson brought to our attention recently).

I normally wouldn't announce an addition to the FAQ like
this, but I noticed that when I began to do this very
thing on the weekend, my FAQ entry was removed.

If this is not a good idea, could someone let me know?
Then I won't bother clogging up the FAQ with entries
which are not appropriate.

Stephen

Re: IncompatableClassError - FYI

[Stephen Adkins]

Dave,

I got the same problem with Blackdown JDK 1.1.8v1.
I wondered if it was a JDK 1.1 vs JDK 1.2 issue.
I upgraded to Blackdown JDK 1.2.2 RC4 and the problem went away.
However, it would be good to know that Turbine still
builds with 1.1.8.

We had a discussion about this over the weekend.

   http://list.working-dogs.com/lists/turbine/Turbine%20Digest%2004-22-00

I will add your solution to the FAQ (under Troubleshooting).

Re: Install problem - Infinite redirect detected...

Thanks for answering.  Unfortunately, that didn't fix it.  One thing I'm
wondering - when I built it, for the JSDK= argument, I used servlet.jar
rather than /JSDK2.0/jsdk.jar because that's the current version of that
library.  Do you think that could have anything to do with it ?

Re:java.lang.ExceptionInInitializerError:java.lang.NullPointerException

[Nissim]

I think you get this when turbine doesn't know where the
TurbineResources.properties file is, or can't open it.  Make sure you
set it in the init parameters, and the file exists and is readable.
