Re: j2sdk1.4.2_01 vs. CLASSPATH problem?

Yasunari:

If I read your email correctly you are able to compile but not run...

If so, you need to do this:

export CLASSPATH=/usr/share/pgsql/postgresql.jar:/home/tosa/pgsqlDev/java

Since client2 "lives" in /home/tosa/pgsqlDev/java that needs to be part of the CLASSPATH...

Hi,

I would really appreciate your help in learning JDBC through PostgreSQL.

Under j2sdk1.4.2_01, setting CLASSPATH causes exception in class not
found error. This exception is thrown even the simplest HelllWorld
class. Did they(SUN) change the behavior of CLASSPATH?

I'm running RedHat 9 with Linux 2.4.20-19.9 kernel.

Here is the details.

/home/tosa/pgsqlDev/java>javac client2.java
client2.java:7: package org.postgresql.util does not exist
import org.postgresql.util.*;
^
client2.java:67: cannot resolve symbol
symbol : class PSQLException
location: class client2
catch(PSQLException e)
^
2 errors

......OK. I set CLASSPATH
/home/tosa/pgsqlDev/java>setenv CLASSPATH /usr/share/pgsql/postgresql.jar
......Now compiles
/home/tosa/pgsqlDev/java>javac client2.java
......However, I cannot run
/home/tosa/pgsqlDev/java>java client2
Exception in thread "main" java.lang.NoClassDefFoundError: client2
......So, I unsetenv CLASSPATH
/home/tosa/pgsqlDev/java>unsetenv CLASSPATH
/home/tosa/pgsqlDev/java>java client2
Exception in thread "main" java.lang.NoClassDefFoundError:
org/postgresql/util/PSQLException
