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?

You try to load the PGtoXML.jar using the system classloader instead of
installing it in the database with sqlj.install_jar, or in other words,
you add the PGtoXML.jar to the PL/Java classpath. This in turn, causes
an illegal file access. PL/Java installs "java" as a trusted language.
Trusted languages have no access to the file system. Try installing
removing PGtoXML.jar from the classpath and instead install it into the
database using install_jar.

I'm not sure what you mean, but I did use sqlj.install_jar to install
the jar files. Here is the sql script I run:
------------------------------------------------------------------------
--------
SELECT sqlj.install_jar('file:///var/lib/pgsql/pljava/xercesImpl.jar',
'xercesImpl', false);
SELECT sqlj.install_jar('file:///var/lib/pgsql/pljava/xml_apis.jar',
'xml_apis', false);
SELECT sqlj.install_jar('file:///var/lib/pgsql/pljava/JDBC.jar', 'JDBC',
false);
SELECT sqlj.install_jar('file:///var/lib/pgsql/pljava/PGtoXML.jar',
'PGtoXML', false);
SELECT sqlj.set_classpath('public', 'xercesImpl');
SELECT sqlj.set_classpath('public', 'xml_apis');
SELECT sqlj.set_classpath('public', 'JDBC');
SELECT sqlj.set_classpath('public', 'PGtoXML');

Ok, that looks good. Still, according to your stacktrace, an attempt is
made to load the PGtoXML.jar using the system classloader which in turn
tells me that either your CLASSPATH environment variable or the
pljava.classpath in the postgresql.conf contains this jar. You should
remove that setting.

Thank you, that seemed to do the trick on the securityexception. But

Something in your code is asking explicitly for the
org.postgresql.Driver. That driver is the client JDBC driver and should
not be used within PL/Java. If it indeed was found, using it would
result in a remote connection to another backend process that runs in a
separate transaction, most likely in combination with a significant
performance hit.
In order to obtain a connection in PL/Java, you must use:
Connection conn = DriverManager.getConnection("jdbc:default:connection");
The Driver in use here will be the org.postgresql.pljava.jdbc.SPIDriver
but you shouldn't normally need to be concerned with choice of driver.

Here is my code that calls the Driver. The host, database, username,
and password all come from another constants file included in the
PGtoXML package. I guess there is something wrong with the way I use
the JDBC driver. I tried removing the import java.sql.* line to stop it
from looking for the JDBC jar files. But now everything is broken
without it. Do I need to rewrite all my code to use the pljava JDBC
driver? Also why is it that this works 100% on a windows system, ( I
can even access the Linux database with the windows postgresql
function)? Thank you for your help, I would have gotten nowhere without
it.
package PGtoXML;
import java.sql.*;
public class OWDBConnection {
private Connection db;
public OWDBConnection() throws ClassNotFoundException, SQLException{
Class.forName("org.postgresql.Driver");
db = DriverManager.getConnection("jdbc:postgresql:" +
Constants.host +
Constants.database,
Constants.username,
Constants.password);
}
public ResultSet getTableNames() throws SQLException{
Statement sql = db.createStatement();
ResultSet results = sql.executeQuery
("select viewname from pg_views where schemaname
= 'public' and viewname like 'xml_%'");
return results;
}
public ResultSet getTableColNames (String name) throws SQLException{
Statement sql = db.createStatement();
ResultSet results = sql.executeQuery
("select column_name from information_schema.columns where table_name =
'"
+ name + "' order by
ordinal_position");
return results;
}
public ResultSet getTableData (String name) throws SQLException{
Statement sql = db.createStatement();
ResultSet results = sql.executeQuery("select * from " +
name);
return results;
}
public static void main (String args[]) {
try{
OWDBConnection demo = new OWDBConnection();
System.out.println("\n");
ResultSet tableNames = demo.getTableNames();
ResultSet tableData;
while (tableNames.next()) {
System.out.println(tableNames.getString(1));
tableData = demo.getTableData(tableNames.getString(1));
for (int i=1; i<=tableData.getMetaData().getColumnCount();
i++){
System.out.print("\t\t\t" +
tableData.getMetaData().getColumnName(i));
}
while (tableData.next()){
System.out.println();
for (int i=1;
i<=tableData.getMetaData().getColumnCount(); i++){
System.out.print("\t\t\t" +
tableData.getString(i));

Only one method needs to be rewritten AFAICS, and that's the
constructor. Try this:
public OWDBConnection() throws SQLException{
db = DriverManager.getConnection("jdbc:default:connection");
}
That should do it. You will still use JDBC (that's just the interfaces)
but now you'll use the PL/Java jdbc implementation. The connection used
by PL/Java is implicit since it reflects the session of the caller of
the function, hence there's need to "login".
If you got your code working on a windows system you probably have an
older version of PL/Java then yor setup must be slightly different
there. PL/Java somehow finds the jar file of the client driver. Perhaps
you had that jar file in your classpath in combination with a sligthly
older version of PL/Java where security was not as tight as it is now?
Eihter that, or you loaded the actual PostgreSQL client driver .jar file
into the database using sqlj.install_jar. As I explained earlier, such a
setup might seem to work although what really happens is that your
function will behave like a client for yet another backend. I have a
hard time thinking of a case when that would be desirable.

Thank you once again. I have one (hopefully last) problem.

I have installed the xerces xml parser the same way I installed the
PGtoXML jar file. Is there something else I need to do in order to have
PGtoXML see xerces? How do I set the classpath to be seen? I've
already entered:
SELECT sqlj.set_classpath('public', 'xercesImpl');
SELECT sqlj.set_classpath('public', 'xml_apis');
SELECT sqlj.set_classpath('public', 'PGtoXML');
Also, you were right; I was running pljava 1.0.0 on the windows box. I
have replaced it with the latest version, and now both servers are
broken. But I am sure that once I get this to work it'll be better than
what I used to have.
Once again thank you for you help.

Hello,
try
SELECT sqlj.set_classpath('public', 'xercesImpl:xml_apis:PGtoXML');
instead of
SELECT sqlj.set_classpath('public', 'xercesImpl');
SELECT sqlj.set_classpath('public', 'xml_apis');
SELECT sqlj.set_classpath('public', 'PGtoXML');
If you set the classpath three times, only the last one is effective. You should set it only once using a colon separated string.
Thomas, I think there could be one reason to use explicit JDBC driver within PL/Java routine if you want to log something in an autonomous transaction (if your session crashes or is rolled back, logged items remain saved). However, I don't think that this would be the Joves's case.

Yes, that would be a special case where it (perhaps) would make sense
although the performance hit caused by such logging would be
significant. I wouldn't recommend it. One major reason to move
functionality into functions is to get rid of the overhead of using a
remote process. Logging through a client jdbc driver will introduce that
overhead once again and every session that uses it will tie up two
backend processes. I'm not sure of what use case you are thinking of but
perhaps it can be solved using the standard java.util.log.Logger?
Entries written there ends up in the backend log. Formatted the right
way they should be easy to parse if need be.

I had to change my e-mail. My work e-mail wasn't receiveing the
messages (reason why I had to start a new thread everytime).
Thanks Filip for your help. I've gotten one step closer to finishing
this up. But now when I start postgresql and run the function I get
this:
LOG:
LOG: An unexpected exception has been detected in native code outside the VM.

Does the pljava JDBC work diffrently than the postgresql JDBC I was

Again you guys have been tremendous hlep.

The file "hs_err_pid2317.log" will be present somewhere under your
<PostgreSQL data>/base/<some number> directory. Can you please attach
that file and email it to me?

Yes, that's possible although all things that are standardized should
work the same way. The conversion from boolean to string is standardized
so you have encountered a bug in PL/Java.

When you say a bug in PL/Java, does that mean there isn't much I can
do to fix it?
What about the:
LOG: An unexpected exception has been detected in native code
outside the VM.
LOG: Unexpected Signal : 4 occurred at PC=0x4915444C
LOG: Function=
LOG: [Unknown.
Is that also a bug in PL/java, or is that something I should be looking to fix?
If that is indeed something I can't fix, is there anywhere I can get
the 1.0.0 release so that I can rool everything back to when it was
working? I don't mind the performance really since the java
application will be runned maybe once or twice per day.
Thank you

You can always change your code to do a getBoolean() to fetch boolean
values instead of getString().

I don't know. That's why I want you to send me the "hs_err_pid2317.log"
file.

If it's broke in 1.1, I doublt it will be working in 1.0.

I am looking at the PL/Java source and my code. I see that the
problem is I am trying to get the string of the data and put it into
an xml node attribute. The problem comes when the JDBC returns the a
sql boolean as a boolean object and the toString method can not handle
it. I am not sure what the correct standard for this is, but the
postgresql JDBC allowed it. I will change my code accordingly.

Sorry I didn't read that part originally. I will include it with this e-mail
> If it's broke in 1.1, I doublt it will be working in 1.0.
I think the reason that it worked in 1.0 was because the lower
security allowed me to add the Postgresql JDBC to the classpath and
the Postgresql JDBC was able to handle a toString() on all data types.

Thanks. Unfortunately that log didn't reveal anything at all. What exact
version of PL/Java are you using? Is it a pre-compiled binary? Would it
be possible for you to try the latest CVS?

I am using 1.1.0b1. I changed my code from:
data.getString(i);
to:
data.getObject(i).toString();
And it seems to work. It still crashes the first time I run the
function when I log into postgresql though. But it'll work if I just
restart postgresql, which I will add to my script. And randomly I
will get this:
LOG: Exception
LOG: in thread "main"
java.sql.SQLException: Stale Handle to native structure

at org.postgresql.pljava.sqlj.Loader.getSchemaLoader(Loader.java:88)
ERROR: java.sql.SQLException: Stale Handle to native structure
Also, although I get my xml string, there is alot of junk in front of it.

Right, I think you encounter a bug that has been fixed in CVS head, so
if you have a chance to get the source-tree using CVS and then compile
and test again using that, it would be very helpful.
A bugfix that greatly improves the ResultSet type mappings is in the
works by the way. I hope to get it in tonight.

Do you mean the java.sql.SQLException: Stale Handle to native structure
or the error that I already fixed?

Oh, sorry. I mean both. Or to clarify, the "Stale Handle" is a bug that
I belive has been fixed in CVS already. A fix for the bug that you found
a good workaround for using getObject().toString() will be commited shortly.

Great, I'll try the cvs version and wait for the new release. I'll
let you know if I get any more problems after that.

Because you have not done as I suggested and removed it from your
CLASSPATH. Consequently, the system classloader tries to load it from
disk instead of from the database.

Joves,
I'm still awaiting some input that might indicate that some problem
remain. I hope to resolve everything and release in matter of days.
Can't give you an exact date though.

I wrote a litlle class test to see pljava in action. This class named
test.jar and the jar name used in the install routine is test_luca.
My procedure is very simple:
public class Test {
public static String test() {
String ret = "nu cazz!!!!!!!!";
try {
Class.forName("org.postgresql.Driver");
String url =
"jdbc:postgresql://myhost/mydb";
Properties props = new Properties();
props.setProperty("user", "user");
props.setProperty("password",
"password");
Connection conn =
DriverManager.getConnection(url, props);
Statement s =
conn.createStatement();
int uid = 13;
String _url = "some url";
String sql = "insert into
request(UID, url) values(" + uid + ", '" + _url + "')";
s.execute(sql);
s.close();
s = conn.createStatement();
sql = "select * from request where
uid = 13";
ResultSet rs = s.executeQuery(sql);
rs.first();
ret = rs.getString("url");
rs.close();
conn.close();
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
ret = "non ho trovato la classe del
dirver jdbc!!";
//e.printStackTrace();
} catch (SQLException e1) {
ret = e1.getMessage();
//e1.printStackTrace();
}
return ret;
}
}
when I try to execute this is the result:
SELECT test_luca();
ERROR: java.lang.SecurityException: read on \C:\Program
Files\PostgreSQL\8.0\jdbc\postgresql-8.0-310.jdbc3.jar
Some body can help me?
Thanks in advance,
Luca

1) Don't use the PostgreSQL client jdbc driver inside of PL/Java since
that will a) create a network connection to another PostgreSQL session
and b) have a transaction-scope that is decoupled from the
transaction-scope of the executing function. In order to obtain a
connection, please do:
Connection conn = DriverManager.getConnection("jdbc.default.connection");
2) Never have anything but the pljava.jar in the postgresql.conf
variable pljava.classpath or in the CLASSPATH env seen by the postmaster
process . Jar files *must* be loaded using sqlj.install_jar

I made as you suggested. But the result now is: no suitable driver.
The CLASSPATH does not exist and in the postgresql.conf
variable pljava.classpath has only pljava.jar.
this is my change in the source
public class Test {
public static String test() {
String ret = "nu cazz!!!!!!!!";
try {
/*
Class.forName("org.postgresql.Driver");
String url =
"jdbc:postgresql://etechsviluppo.cefriel.it/context";
Properties props = new Properties();
props.setProperty("user", "context");
props.setProperty("password", "context");
Connection conn =
DriverManager.getConnection(url, props);
*/
Connection conn =
DriverManager.getConnection("jdbc.default.connection");
Statement s = conn.createStatement();
...
thank you,
Luca

You should use
