missing dependancy?
Steve Hansen
I get the following run time error:
java.lang.NoClassDefFoundError: com/merant/jdbcspy/SpyLogger
at com.microsoft.jdbcx.base.BaseDataSource.getConnection(Unknown
Source)
at Main.main(Main.java:14)
Exception in thread "main"
I've search the supplied jar files and I can find no reference to SpyLogger
anywhere! Has com/merant/jdbcspy/SpyLogger been left out?
Using DriverManager.getConnection seems to work ok.
Has anyone used the com.microsoft.jdbcx.sqlserver.SQLServerDataSource
approach?
Below is a code snipet of what I'm trying to do..
code (snipet):
import java.sql.*; // import JDBC2.0 core
import javax.sql.*; // import optional package
import javax.naming.*; // jndi naming api
public class Main {
public static void main(String args[]){
try {
com.microsoft.jdbcx.sqlserver.SQLServerDataSource
ds = new com.microsoft.jdbcx.sqlserver.SQLServerDataSource();
ds.setServerName("192.168.0.6:1433");
Connection con = ds.getConnection("sa","");
....

maybe joseph or sarah?
I just came up with the same problem and was coming here to get an answer
(possibly):
here's my code (not using JNDI obviously):
ssds = new SQLServerDataSource();
ssds.setServerName("192.168.75.203");
ssds.setPortNumber(1433);
ssds.setDatabaseName("shanghai");
ssds.setUser("sa");
ssds.setPassword("p4r4d1s0");
msdatasource = (DataSource) new SQLServerDataSource();
so you see my problem? it's that last line. So the error message you got
was the one i received when (subsequent to having set up the datasource like
this) i called getConnection().
After fixing the code like so:
ssds = new SQLServerDataSource();
ssds.setServerName("192.168.75.203");
ssds.setPortNumber(1433);
ssds.setDatabaseName("shanghai");
ssds.setUser("sa");
ssds.setPassword("p4r4d1s0");
msdatasource = (DataSource) ssds;
I still get the same error.
java.lang.NoClassDefFoundError: com/merant/jdbcspy/SpyLogger
at com.microsoft.jdbcx.base.BaseDataSource.getConnection(Unknown Source)
at
com.ivianetwork.shanghai.util.ShanghaiConnectionFactory.getConnection(Shangh
aiConnectionFactory)
(ShanghaiConnectionFactory is my class that simply calls getConnection() on
the DataSource)
so we're in the same boat. Anyone?

could see if that "missing" class was even provided)...don't know if this is
relevant:

can we use setLogWriter to get around this? not sure, investigating.....

i even went back and unjarred the mssqlserver.jar (the one giving jar a
headache) using winzip, then rejarring it manually. The jar is no longer
corrupt. But i still get this same error.

I went with a set of wrapper classes that I used to use that would make a
JDBC 1.0 Driver look like a JDBC 2.0 DataSource, and also implements its own
Connection pool. So I'm treating the MS driver as a "dumb" driver (1.0).
Now i'm getting the "cloned connections / transactions" problem everyone
else on this newsgroup has already had ;)

I guess you are using a jdk 1.2 or higher so this
probably is a security issue.
Security has changed considerably in the Java2 platform,
from a pure sandbox to an access control list (acl)
based security scheme.
Here are the 2 steps for an allow all security policy:
a) provide a java.policy file
---start---
grant {
permission java.security.AllPermission;
};
---stop---
b) add -Djava.security.policy=java.policy to your command that invokes
your application (and your JavaVM as a result)
java -Djava.security.policy=java.policy com.mycompany.MyApplication
In a deployment scenario you should change the allow all to something
more suitable.
With kind regards,
Koen
