[Pljava-dev] java.lang.SecurityException

[Joves Luo]

Someone please help me, this is driving me crazy.

 

 

I wrote a java program that accesses a database and turns the data into
an xml string.  I then use php to write that string to an .xml file.
Originally I was developing the program on a windows 2k server using
Apache 2, php5, and postgresql 8 with pljava.

 

My boss wanted me to move the server onto a Linux 7.3 box.  So now the
entire thing is sitting on a Linux 7.3 server with Apache 1.3, php4, and
postgresql 8 with pljava.

 

Everything works except for the java application.  I run:

 

select getxmlstring();

 

and I get:

 

ERROR:  java.lang.SecurityException: read on
/var/lib/pgsql/pljava/PGtoXML.jar

 

 

Here is the stack trace from the log file:

I tried looking at the source code of pljava.internal.Backend, but there
are 3 places where the exception can be thrown.  Can someone please help
me out?
