[Pljava-dev] Help with pljava on centos 4.4, java 1.5.09, cvs pljava. with src rpm of postgresql 8.2.1

[Joshua Ross]

I had this problem today.  The issue is the libjvm.so is not linked.  To 
verify this is the case execute the ldconfig command.  Generally, ldconfig 
is in /sbin/ or /usr/sbin/:

>  /sbin/ldconfig -p |grep libjvm.so

If you don't get a response then it is not linked.  So you need to add the 
path to that library file in the ld.so.conf.  If you followed the 
instructions you probably created the file /etc/ld.so.conf.d/postgresql and 
added a few directories in it.  On redhat I found that the file 
/etc/ld.so.conf.d/postgres does not get sourced by the ldconfig command. 
This is becuase it was expecting a file with a .conf extension(there are way 
to check this).  So renaming the file /etc/ld.so.conf.d/postgresql to 
/etc/ld.so.conf.d/postgresql.conf got the file correctly sourced.  Then I 
ran ldconfig again to rebuild the library list.  Afterwards, running the 
command above returned the correct result:

> /sbin/ldconfig -p |grep libjvm.so
        libjvm.so (libc6,x86-64) => 
/usr/java/jdk1.5.0_11/jre/lib/amd64/server/libjvm.so

If you don't have the file /etc/ld.so.conf.d/postrgresql or posgresql.conf 
created then you should create it.  The file should have something like 
this:

<jre_home>/lib/i386/
<jre_home>/lib/i386/client

Where <jre_home> is the location of your JRE.  This will vary depending on 
your setup.  For mine, I had java in /usr/java/jdk_1.5.0_11/ and the box is 
a 64-bit machine.  So my file looked like this:

/usr/java/jdk_1.5.0_11/jre/lib/amd64
/usr/java/jdk_1.5.0_11/jre/lib/amd64/server

To correlate what these directories mean to your error message, my libjvm.so 
file is located here:

/usr/java/jdk_1.5.0_11/jre/lib/amd64/server/libjvm.so


Hope this helps someone, we spent some time trying to get everything all 
configured after building from cvs HEAD.

Hi All,

I am in quite the quandry with pljava.  I continue to get this message:

ERROR:  could not load library "/usr/lib/pgsql/pljava.so": libjvm.so: failed 
to map segment from shared object: Permission denied

I am using:

centos 4.4
java 1.5.09
src rpm of postgresql 8.2.1
cvs latest of pljava

Any ideas, or anything I could try?


Pertinent entries in /var/lib/pgsql/data/postgresql.conf

dynamic_library_path = 
'$libdir:/var/lib/pgsql/org.postgresql.pljava/build/objs'
custom_variable_classes = 'pljava'              # list of custom variable 
class names
pljava.classpath = '/var/lib/pgsql/org.postgresql.pljava/build/pljava.jar'


ldconfig shows:
[root at DESN-OFF1 ~]# ldconfig -v |grep jvm
        libjvm.so -> libjvm.so
[root at DESN-OFF1 ~]# ldconfig -v |grep pljava
/var/lib/pgsql/org.postgresql.pljava/build/objs:
