Re: Error deploying tapestry on specific server. (more info)
I found the following in the logs of my shared server, how could the setup of this server cause this IllegalAccessException?
Unable to process client request.

Re: Error deploying tapestry on specific server. (more info)
Posted by Geoff Longman <gl...@intelligentworks.com>.
I had an IllegalAccessError recently using Hivemind. I was going nuts
looking for things like those described in this thread already.
Turned out I had made a class abstract but not public.
>From the java language specification:
<quote>
12.3.3 Resolution of Symbolic References
IllegalAccessError: A symbolic reference has been encountered that specifies
a use or assignment of a field, or invocation of a method, or creation of an
instance of a class, to which the code containing the reference does not
have access because the field or method was declared private, protected, or
default access (not public), or because the class was not declared public.
This can occur, for example, if a field that is originally declared public
is changed to be private after another class that refers to the field has
been compiled
</quote>
Could one of the cases above be the problem?

resin's ability to take a web app with no class files and dynamically
compile the java files while deploying it (or when the java files change).
Basically I just uploaded the java files in place of the class files when
deploying the app and resin compiled everything for me. All my libraries are
placed in the lib folder of the app so resin should have used the same
libraries to compile and to run. Furthermore, I've tested the app on my own
resin server (different from the tomcat server I use to develop) and it
worked perfectly.

Re: Error deploying tapestry on specific server. (more info)
Posted by Kris Rasmussen <kr...@yahoo.com>.
I already checked with the tech who runs the shared server and he doesn't think there could possibly be any other libraries that conflict. Besides, I think my lib directory has priority over the centralized one. Also, the error is in accessing the enhanced PageLink (or any enhanced component I place in any app I try), so I would think that is has to have to be related to javaassist and runtime class modification. IllegalAccessExceptions are usually related to public/private kinds of things and not the SecurityManager so I don't know what could be causing this. If anyone gets any ideas please let me know.

Jonny Wray <jo...@yahoo.com> wrote:
Kris,
Ah, I understand now - did't know resin could do this.
Have you checked the centralized lib directory for the whole
installation of resin to see if there's another version of any apps
around that conflict with your WEB-INF/lib versions?
That's about the only thing I can think of. I don't know resin, but as
I said I've never heard of any configuration properties that could do
this, but it must be a difference between the two versions as you have
your code working on the other.
I maybe wrong but I thought the Illegal in IllegalAccessException was
more on the lines of trying to access a private/protected method or
field by reflection, rather than a security (eg jaas) thing.

RE: Error deploying tapestry on specific server. (more info)
Posted by Kris Rasmussen <kr...@yahoo.com>.
Thats because the methods are created at runtime by java assist. Anyways, suprisingly while I was looking for something unrelated about rc1 in the mail archives a message came up from tapestry-dev about my exact problem. As I thought it is related to the security manager in place on the shared server I am using. The title of the thread is [Patch] Tapestry 3.0 RC1 in secure Tomcat 5.0 (its about tomcat but I'm sure the same goes for resin).

Hi,
I looked very quickly at the PageLink class and .jwc. As far as I can tell,
in rc1, there's no property called templateTagBinding in the .jwc, and no
methods defined in the class (I even tried a "grep -i templatetagbinding" in
all the .java and .jwc files). Are you using rc1 or beta4? If you're on
beta4, I'd try switching to rc1 just to see what happens.

Re: Error deploying tapestry on specific server. (more info)
Posted by Kris Rasmussen <kr...@yahoo.com>.
Thanks, I should have pointed out that I was using beta 3. However, If the security manager is was keeps even this from working then I doubt the rest of my application will run as there will be many other enhanced classes. However, I'll still give it a try with rc1 when I get a chance and let you know how it works.

It used to, in an old beta version (beta2 or beta3, cannot remember exactly
at the moment). Currently this has been optimized and is added only to
components that have this parameter defined (such as Any), but it is
definitely not added to components such as PageLink.

to get my client's current shared hosting provider to mess with their

Re: Error deploying tapestry on specific server. (more info)
Posted by Mindbridge <mi...@yahoo.com>.

its not there because it is a method that tapestry adds to every component
It used to, in an old beta version (beta2 or beta3, cannot remember exactly
at the moment). Currently this has been optimized and is added only to
components that have this parameter defined (such as Any), but it is
definitely not added to components such as PageLink.

to get my client's current shared hosting provider to mess with their

RE: Error deploying tapestry on specific server. (more info)
Posted by Kris Rasmussen <kr...@yahoo.com>.
I'm still not sure that was the problem, but if you read the message in the tapestry-dev mailing list you will probably be pretty convinced. I too thought that a SecurityManager would throw a SecurityException, but maybe there is more too it that I am just not seeing. Anyways, rather than trying to get my client's current shared hosting provider to mess with their security manager configuration I am going to switch him over to a vps server for now.
As to not finding the get templateTagBinding in the .jwc and .page files, its not there because it is a method that tapestry adds to every component (that may not be 100% correct), but if you search again this time for 'templatetag' I think you will find something.

Hm, did that solve your problem? That's a surprise to me, I was sure that
IllegalAccessException was only about Java-level problems
(public/protected/private, etc), and that a SecurityManager would always
throw a SecurityException.
Also, as I understand it, Tapestry (using javassist) enhances the classes
based on .jwc and .page files. Which is why I looked in the .jwc files as
well for the TemplateTagBinding.
This is getting interesting - please let us know what the final solution is!

Hm, did that solve your problem? That's a surprise to me, I was sure that
IllegalAccessException was only about Java-level problems
(public/protected/private, etc), and that a SecurityManager would always
throw a SecurityException.
Also, as I understand it, Tapestry (using javassist) enhances the classes
based on .jwc and .page files. Which is why I looked in the .jwc files as
well for the TemplateTagBinding.
This is getting interesting - please let us know what the final solution is!

RE: Error deploying tapestry on specific server. (more info)
Posted by Kris Rasmussen <kr...@yahoo.com>.
Thats because the methods are created at runtime by java assist. Anyways, suprisingly while I was looking for something unrelated about rc1 in the mail archives a message came up from tapestry-dev about my exact problem. As I thought it is related to the security manager in place on the shared server I am using. The title of the thread is [Patch] Tapestry 3.0 RC1 in secure Tomcat 5.0 (its about tomcat but I'm sure the same goes for resin).

in rc1, there's no property called templateTagBinding in the .jwc, and no
methods defined in the class (I even tried a "grep -i templatetagbinding" in
all the .java and .jwc files). Are you using rc1 or beta4? If you're on

Re: Error deploying tapestry on specific server. (more info)
Posted by Kris Rasmussen <kr...@yahoo.com>.
I can't shutdown the server since its shared. At this point I am running out of time so I think I am going to have to switch over to another host. I am in the process of setting up my own servers but in the mean time I need a cheap place to host my clients site. Anyone got any recommendations?
Thanks for all the ideas and trying to help.

I'd never assume that the web-inf/lib jars take priority. That certainly
wasn't the case for me in the past. I think it very much depends on the
class loading strategy of the app server. Still, if it's a basic
installation of resin then looks like that's not the problem.
I don't know what else to suggest. I thought of the library conflict as I'd
seen this error before and that was the cause, although not with tapestry.
That fact coupled with the fact that your app works on one instance of resin
and not another suggested that to me.
I guess one thing I'd try - are you just hot loading the app into the shared
server or have you tried shutting down, deploying then restarting. Maybe the
app server is caching the classes. I'm grasping at straws now, sorry I can't
be of any more help.

Re: Error deploying tapestry on specific server. (more info)
Posted by Kris Rasmussen <kr...@yahoo.com>.
I don't think it could be a library conflict because the server only has the basica jdk and resin libraries installed (so I am told) and my lib directory should take priority (or so I think).
The problem isn't with another library anyways, its with any enhanced method, specifically the getTemplateTagBinding() which may simply be the first enhanced method that is called. I read in the jboss forums that an IllegalAccess exception can happen when two classes of the same class are loaded into memory so it might be possible that the enhanced classes have been loaded twice in memory. Do the classes that tapestry enhances reside only in memory or are they stored somewhere else?
Thanks again,
Kris

Have you checked the centralized lib directory for the whole
installation of resin to see if there's another version of any apps
around that conflict with your WEB-INF/lib versions?
That's about the only thing I can think of. I don't know resin, but as
I said I've never heard of any configuration properties that could do
this, but it must be a difference between the two versions as you have
your code working on the other.
I maybe wrong but I thought the Illegal in IllegalAccessException was
more on the lines of trying to access a private/protected method or
field by reflection, rather than a security (eg jaas) thing.

Re: Error deploying tapestry on specific server. (more info)
Posted by Kris Rasmussen <kr...@yahoo.com>.
Thanks Jonny. By compiling the app on the server I was reffering to resin's ability to take a web app with no class files and dynamically compile the java files while deploying it (or when the java files change). Basically I just uploaded the java files in place of the class files when deploying the app and resin compiled everything for me. All my libraries are placed in the lib folder of the app so resin should have used the same libraries to compile and to run. Furthermore, I've tested the app on my own resin server (different from the tomcat server I use to develop) and it worked perfectly.
Still, given all this, if you think there is still a way for what you described to be happening, let me know because I can't think of anything else other than what I already mentioned below.

It looks like the illegal access exception is a result of a binding that references a method getTemplateTagBinding() of an enhanced PageLink. I see that this method is inserted by tapestry to most components, but I don't understand why an access to it would trigger an IllegalAccessException other than maybe the security settings on the shared server I am using some how prevent it?
Thanks again,
Kris

Kris,
I've never used resin so can't help you with specifics, but of all the app
servers I've used I've never seen any such configuration possibilities.
Not sure what you mean about getting the server to compile the application.
If you mean you compiled the app on the server machine this still does not
eliminate the possibility that you are using a different set of jars for
compiling and another for running. Remember, app servers do not use your
classpath for running.
I'd still look for library incompatibilities. For example, if you are using
Spindle under eclipse it comes packaged with its own version of the tapestry
jars. If you've downloaded your own version of the tapesty jars this could
mean you are compiling with one set of jars but packaging and deploying with
another. I've seen the same exception in the past that was caused by the
same problem (but using struts on Oracle 9ias).

Re: Error deploying tapestry on specific server. (more info)
Posted by Jonny Wray <jo...@yahoo.com>.
Kris,
I've never used resin so can't help you with specifics, but of all the app
servers I've used I've never seen any such configuration possibilities.
Not sure what you mean about getting the server to compile the application.
If you mean you compiled the app on the server machine this still does not
eliminate the possibility that you are using a different set of jars for
compiling and another for running. Remember, app servers do not use your
classpath for running.
I'd still look for library incompatibilities. For example, if you are using
Spindle under eclipse it comes packaged with its own version of the tapestry
jars. If you've downloaded your own version of the tapesty jars this could
mean you are compiling with one set of jars but packaging and deploying with
another. I've seen the same exception in the past that was caused by the
same problem (but using struts on Oracle 9ias).

Re: Error deploying tapestry on specific server. (more info)
Posted by Kris Rasmussen <kr...@yahoo.com>.
Thanks, Jonny, thats definatly possible but I don't know that it is the problem because the server runs resin and I tryed uploading the app's source only and having the server compile from scratch and I still get the same error. Could my server be configured such that the javaassist bytecode generator is able to generate code but my classes are not able to access it (as the following could imply)?
java.lang.IllegalAccessException: Method [public
org.apache.tapestry.IBinding

cannot be

Does tapestry cache out these dynamically generate classes anywhere or is it all done in memory?
Thanks,

Re: Error deploying tapestry on specific server. (more info)
Posted by Jonny Wray <jo...@yahoo.com>.
This looks to me like a versioning problem with libraries ie, you've
compiled against one version of a library and are running with another. This
error occurs when method is reflectively accessed (ie at runtime) but it
cannot be found.
I'd check the version of the various external libs you are using on the
shared server, and also check there's not multiple version of the same
libraries around.
