I don't know in which library it resides, but I have a similar problem with a different library, since my connexion uses Unix sockets. You can look at the content of the shared library using the nm command. The symbol prefixed by a U are the undefined symbols and the symbols defined within the library are prefixed with a T. For example, nm libjkjni.so | grep md5 will produce the following output: U apr_md5_final U apr_md5_init U apr_md5_update c460 T jk2_md5 The jk2_md5 symbol is defined within the library and it probably requires apr_md5_final, apr_md5_init and apr_md5_update which are tagged undefined. $ nm libaprutil-0.so.0.9.5 | grep md5 8590 T apr_md5 8f80 T apr_md5_encode 84d0 T apr_md5_final 82a0 T apr_md5_init 82e0 T apr_md5_set_xlate 8330 T apr_md5_update Shows required symbols are in the libaprutil-0.so.0.9.5 shared library. Normally, with a right shared library configuration /etc/ld.so.conf or appropriate LD_LIBRARY_PATH, the required symbols in libjkjni.so should be resolved properly. And the error message from your catalina.out logfile should not appear. Now, why it happens? I just don't know. I am getting a apr_md5_final undefined symbol error even if my configuration seems OK.

Allan, the problem lies with the link-edit while building the mod_jk2.so
module. The Makefile produced in the some_path/native2/server/apache2/
is buggy. There is some important libraries missing in the list.
Also, I believe the configure is not checking everything properly. All
prereqs should be check at the configure step and flagged if not
satisfied.
You can refer to the following final discussion in the current mailing
list:
http://www.mail-archive.com/[EMAIL PROTECTED]/msg104016.html
What is missing, is the proper JK_LDFLAGS definition which should be:
JK_LDFLAGS=-L${APACHE2_LIBDIR} -lcrypt -lapr-0 -laprutil-0 -lgdbm
-lexpat -ldb-4.0 -lpthread -ldl
In my case, everything after -lcrypt was missing. And since we are
building shared objects, symbols are resolved at runtime rather than at
compile or link-edit time.

It is supposed to make possible changes in the context without having to restart Tomcat. But, I was not able to make this working as documented... ;-( Since I am a newbie, I sticked as much as possible on the instructions. But, it seems not to work as documented. Le lun 08/03/2004 à 22:21, Parsons Technical Services a écrit : Harry, Take a look at this page: http://jakarta.apache.org/tomcat/tomcat-4.1-doc/config/globalresources.html As noted on the page: This is equivalent to the inclusion of the following element in the web application deployment descriptor (/WEB-INF/web.xml): The question is: Is the fragment below inside a context for your application or is in the GlobalNamingResources section? I just swapped mine to Global and dropped the segment in the web.xml. I didn't try it while I had it in the context of the app. Doug www.parsonstechnical.com - Original Message - From: Harry Mantheakis [EMAIL PROTECTED] To: Tomcat Users List [EMAIL PROTECTED] Sent: Monday, March 08, 2004 3:37 PM Subject: JNDI Datasource Reference in DD Not Necessary? Hello For some time now I have implemented the Tomcat 'JNDI DataSource' How-To on connection pooling, and everything has been fine. I define a resource in the context fragment: Resource name=jdbc/postgres auth=Container type=javax.sql.DataSource/ ResourceParams name=jdbc/postgres ... /ResourceParams And a resource reference to it in the deployment descriptor: resource-ref descriptionDB Connection/description res-ref-namejdbc/postgres/res-ref-name res-typejavax.sql.DataSource/res-type res-authContainer/res-auth /resource-ref And then do a JNDI lookup at runtime: return ( DataSource )new InitialContext(). lookup( java:comp/env/jdbc/postgres ); Magic. The other day I noticed that the resource reference in my deployment descriptor was actually broken - the name did not match that defined in the context - and yet my application was still working - perfectly. When I thought about it, it occurred to me that the resource reference in the deployment descriptor may not actually be necessary. So I deleted the resource reference from the web.xml file, and everything still works as expected. Can anyone enlighten me? Many thanks in anticipation.

RE: problem with tomcat shutdown on solaris
Le ven 05/03/2004 à 08:47, Shapira, Yoav a écrit : As I remember, tomcat (including this specific version) will often leave some sort of background thread running even when the shutdown script has been successfully executed. What are you talking about? You remember this from where? Tomcat doesn't leave any of its threads running when the shutdown script successfully executes. I am experiencing this kind of problem; background threads still running after the shutdown script has successfully exited. I just added a few lines in my own script to grep all those processes and signalled them. However, I must say I also have another server on which the shutdown is clean. I don't have time to investigate further this problem. On both servers I am using Tomcat 5.0.19. They are both Redhat Linux machines (but different kernel level and some other packages are not at the same level). -- === Daniel Savard === - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
