Re: IllegalAccessError when run from Tomcat

[Peter Davison]

Has anyone found a solution for this problem yet?

I've scanned the news groups, search the web all to no avail.
This error happens in my servlet when I used JTidy to parse an uploaded file.

Any help would be greatly appreciated.

Thanks.
Pete.

Re: IllegalAccessError when run from Tomcat

[sappling]

After further investigation this seems to be something specific to the
4.0b5 version of Tomcat.  It does not occur in 3.3 milestone 3 or 3.2.  I
think this may indicate a  classloader problem.  I will investigate further
and post something to the bug database.  Thanks for your suggestions.

This is a good suggestion. However,  I have been working with Jini for
awhile where classes: inner and otherwise are being shipped, deserialized
and loaded cross the world, but didn't run into this one.  Although
MarshalledObject wrapper
protects classes from being misinterpreted in my case.

We'll keep digging.

Re: IllegalAccessError when run from Tomcat

[Robert Schweng]

hi,
could it be, it is in reason that classes over the web are interpreted
as URIs.
many systems could cause trouble when
interpreting a dir path like com.class.class$innerclass
to com/class/class?innerclass in Linux
or on NT to com\class\class?innerclass


cheers

It seems that way. This is linkage error, meaning, it went thru compiler
fine, but at run time the field definition changed.

Re: IllegalAccessError when run from Tomcat

Good idea, I didn't realize System.getSecurityManager existed.  It is
returning null, so there is no SecurityManager established and that isn't
my problem.  Anyone have other ideas?  I'm pretty sure this is legal, it
works when not run under Tomcat, and it is 3'rd party code I'm running so I
don't want to pull out the inner class.  This is happening in JTidy.  JTidy
isn't used anywhere else in Tomcat is it (in one of the standard jars)?  Do
I have some wierd conflict between different versions of classes with the
same name?  I searched, but didn't find anything like that.  Thanks for the
ideas so far - I would love some other suggestions on what to try?

Re: IllegalAccessError when run from Tomcat

[Robert Schweng]

i am not perfectly sure, but as far as i know
are inner classes  in beans not allowed!!.
so i could imagine this is also a fact for
servlets.
but dont ask me why.
anyway would it be worth to try cause its pretty simple to make
the inner classe outer classes.

cheers

Put:
System.out.println(System.getSecurityManager()) into your program.
Let us know what it says.

IllegalAccessError when run from Tomcat

[sappling]

When running a servlet from within Tomcat I get the following exception:

java.lang.IllegalAccessError: try to access field org.w3c.tidy.ParserImpl._parseHead 
from class org.w3c.tidy.ParserImpl$ParseHTML
 at org.w3c.tidy.ParserImpl$ParseHTML.parse(ParserImpl.java)
 at org.w3c.tidy.ParserImpl.parseDocument(ParserImpl.java)
 at org.w3c.tidy.Tidy.parse(Tidy.java)
 at org.w3c.tidy.Tidy.parseDOM(Tidy.java)
...

A method in the inner class $ParseHTML is trying to access a private field
_parseHead in the containing class, but that is legal as far as I know.
When I move the body of this servlet to a stand alone application it runs
fine - no exceptions.  Is there some strange JVM security manager here that
is different from running as a real application?  Anyone have an idea what
is going on?
