Context Descriptors
The following regarding Context Descriptors is in the documentation for
Tomcat 6. I'm wondering why the included contexts such as /examples, /docs,
/host-manager, and ROOT (/) don't have Context Descriptors generated as
described below.
The locations for Context Descriptors are;
$CATALINA_HOME/conf/[enginename]/[hostname]/context.xml
$CATALINA_HOME/webapps/[webappname]/META-INF/context.xml
If a Context Descriptor is not provided for a Context, Tomcat automatically
creates one and places it in (1) with a filename of [webappname].xml
although if manually created, the filename need not match the web
application name as Tomcat is concerned only with the Context configuration
contained within the Context Descriptor file(s).
The only one that I see one for is /manager, which leads to my next
question. Why, under /manager, do I see the following in
/manager/manager.xml:
<Context docBase="${catalina.home}/server/webapps/manager"
privileged="true" antiResourceLocking="false"
antiJARLocking="false">
<!-- Link to the user database we will get roles from -->
<ResourceLink name="users" global="UserDatabase"
type="org.apache.catalina.UserDatabase"/>
</Context>
And the following in /manager/META-INF/context.xml? Why the presence of two
context descriptors?
<Context antiResourceLocking="false" privileged="true" />
And finally, why do I see the docBase as
"${catalina.home}/server/webapps/manager" in the previous manager.xml, when
the default Tomcat 6 installation doesn't even have a server directory? What
confuses me is how it still works even when that directory isn't there or
created.

Hi,
first of all: this is a gcc question. If you search for a high quality
answer, you should contact the gcc commmunity.
My personal way to do this (and there is definitely more than one wait
to do it):
export CC="gcc -specs=/path/to/my/specs"
Contents of file /path/to/my/specs:
*libgcc:
-lgcc -lgcc_eh
Now whenever you use a build system, that respects the CC env variable
(e.g. most configure based systems), libgcc should get compiled in
statically.

RE: [SOLVED]Tomcat native library Not found in Solaris 9
Posted by Lakshmi Venkataraman <la...@foundrynet.com>.
Hi Rainer,
Thanks for your suggestion! Using the specs file as suggested below did
not work.
Also, gcc -dumpspecs > /path/myspecs and then changing the *libgcc rule
did not
work either.
What finally worked was
export CC="gcc -static-libgcc"
But then I had to recompile OpenSSL, APR and then Tomcat native in that
order with the
above value for CC to completely remove the dependency on libgcc_s.so.
So now I have libssl.so, libcrypto.so, libapr-1.so and libtcnative-1.so
without the dependency on libgcc_s.so.
Thanks
Lakshmi

I am running into some issues while trying to compile gcc.

It's very likely, that it depends on the same lib in RedHat. You can
check by using "ldd libtcnative-1.so".
The difference is: gcc is a fundamental part of the OS with Linux, so
libgcc_s.so is ususally installed in a standard library location for
Linux. Under Solaris it's an optional add-on installed in a separate
place.
Personally I always find it anoying, that gcc put's a dependency on its
own runtime lib into the compiled code. You could prevent it doing so,
by changing its specs file (tehreby compiling in its convenience
routines statically).

I attached an eclipse debugger and found that an UnsatsfiedLinkError was
thrown due to the
Fact that libtcnative-1.so depends on libgcc_s.1.so.
Then I included /usr/local/lib in LD_LIBRAY_PATH.
Tomcat's Http11AprProtocol connector starts up without any problem.
It is still not clear why on solaris 9 libtcnative-1.so depends on
libgcc_s.1.so
Whereas in Lunux redhat 4 it does NOT do do.

In the one month that I have been in this forum, people ask this
question in
so many different words under so many different subject headings.
My own question, the newbie that I am started out with similar
questions.
Documentation is NOT CLEAR. I hope somebody who has the authority to
change the documentation does so.
Another suggestion, Chuck, since you are always responding to any
context related qeustion, if
you find some time, may be you should mail an FAQ post on this forum on
the topic of "contexts
and deployments" with example directory layouts.
