1: webmail troubles

Posted by loris bason on 12/21/00 01:54 PM

Hi,
In order to reate a virtual user I added the line

+webmail-:postgres:1010:1012:/home/nsadmin/qmail/alias:-::

to /var/qmail/users/assign
However when I run /var/qmail/bin/qmail-newu:

qmail-newu: fatal: bad format in users/assign

another problem:

when I try to send a message, after I have created an account in
webmail, the following error message appears:

DATABASE ERROR

invalid command name "ns_java"

I hope someone can help me

You need a dot by itself on the last line of your or your users/assign file.

Webmail depends on the aolserver module nsjava which is available here.

Dan,
thank you for your prompt replay. The dot on the new line works.
regardind the second question....
I did it!
I have installed the java library libnsjava.so
and added to the configuration file the following lines:

ns_section "ns/server/${servername}/module/nsjava"

ns_param EnableJava "on" ;# Set to on to enable nsjava.

ns_param VerboseJvm "off" ;# Same as command line -debug.

ns_param LogLevel "Notice"

ns_param DestroyJvm "off" ;# Destroy jvm on shutdown.

ns_param DisableJITCompiler "off"

ns_param ClassPath "/usr/local/jdk1.2.2/lib/classes.zip:/home/oacs/www/webmail/java:/home/aolserver/bin/nsjava.jar"

ns_section "ns/server/${servername}/modules"

ns_param nsjava= "libnsjava.so"

but something is probably wrong because in the server.log:

Notice: modload: loading '/home/aolserver/bin/libnsjava.so'
Notice: ModuleInit: Java Module NOT enabled

In the following line:

ns_param      nsjava=       libnsjava.so

remove the '='.

yes, that's right

unfortunately another error message follows

[-jvm-] Error: StartJvm: CreateJavaVM failed

I'm using jdk1.2.2 and Linux 2.2.14-15mdk

Who is the vendor for the jdk that you are using? I never had much luck with the 1.2.2 jdk's on linux, but of course it has been about six months since I tried using one, so the situation may have changed. See the testing summary that I have posted on the nsjava homepage for an idea of which jdk's work.

Were there any other error messages in the log prior to the one that you posted?

Posted by loris bason on 12/21/00 06:58 PM

The vendor is Sun (Classic VM (build 1.2.2-L, green threads, nojit)).

I will download the blackdown jdk1.1.8 this nigth in order to try again tomorrow

No, the error I post you is the only one

Posted by Dan Wickstrom on 12/21/00 07:01 PM

Green threads are definitely a problem. Make sure you get a jvm that uses native threads.

Dan,
I have downloaded and used the blackdown jdk118_v3-glibc-2.1.3.
The result is.... segmentation violation

the log gives the following lines:

I have not found the libjvm.so and libhpi.so libraries in jdk118. Is it normal ?

10: Response to webmail troubles (response to 1)

Posted by Dan Wickstrom on 12/22/00 06:48 PM

Can you run it in gdb and post the backtrace after it crashes, and could you also post the output from running configure?

libjvm.so and libhpi.so are specific to 1.2 jdk's.

The christmas break was nice.

You're posts come out ok, in the email alerts, but they're pretty much incomprehensible on the bboard. When posting something like a log output, you can select html mode and enclose the log listing in <pre></pre> tags to maintain its formatting.

What version of linux are you using? Also, could you run the following and post the results:

1) nsd -V

2) gcc -v

3) java -version

Ok, a few more questions. What do you get for the following:

1) ldd libjava.so

2) ls -l `whereis libpthread`*

15: Response to webmail troubles (response to 1)

Posted by loris bason on 12/27/00 07:42 PM

 [root@fedora /lib]# ldd libjava.so 
libpthread.so.0 => /lib/libpthread.so.0 (0x40077000)
libm.so.6 => /lib/libm.so.6 (0x4008a000) 
libdl.so.2 => /lib/libdl.so.2 (0x400a8000)  
libc.so.6 => /lib/libc.so.6 (0x400ac000)  
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)

ls -l `whereis libpthread`*
ls: libpthread:: File o directory inesistente
-rw-r--r--    1 root     root       837262 mag  5  2000 /usr/lib/libpthread.a
lrwxrwxrwx    1 root     root           25 apr 21  2000 /usr/lib/libpthread.so -> ../../lib/libpthread.so.0*

So It cant't find the libpthread.so library. In /lib I found the libpthread-0.8.so library and I tried to make the symbolik link: /lib/libpthread.so -> /lib/libpthread-0.8.so, but it doesn't work

Last year, I did some development using mandrake 7.0, and I ran into a similar problem where I had an incompatiblity between the version of libpthreads installed with mandrake 7.0 versus the version of libpthreads that libjava.so was linked against. I would be willing to bet that the libjava.so library was probably compiled on a redhat machine. Anyway, I played around with it some, but I didn't ever find a good solution to fixing the problem. I eventually switched to redhat 6.2 for development, and the problem went away. Before, you do anything else, you might want to try using blackdown's jdk118_v1 instead of v3. It might be linked against an earlier version of libpthreads.
