Can not config the connection pool of mssql
DB with jdriver of weblogic,show
java.lang.NullPointerException
Hi,my friends ! I am a beginner of jboss and I want
to use mssql server as my database ,but when I follow
the steps of the jboss docus to config the jboss, it
show me a exception : java.lang.NullPointerException,
I cannot find the reasons , any advices make me
appreciate ,thanks !!My configurations are below:
1. Envionment Info:
Container: JBoss-2.2.1_Tomcat-3.2.1
Java version: 1.3.0,Sun Microsystems Inc.
Java VM: Java HotSpot(TM) Client VM 1.3.0-C,Sun
Microsystems Inc.
System: Windows 2000 5.0,x86
DataBase: MSSQL SERVER 2000
2. jdbc driver:
I put the weblogic.jar into the director of
D:\JBoss-2.2.1_Tomcat-3.2.1\jboss\lib\ext and config
the jboss.jcml ,look below:
<mbean code="org.jboss.jdbc.JdbcProvider"
name="DefaultDomain:service=JdbcProvider">
<attribute
name="Drivers">weblogic.jdbc.mssqlserver4.Driver,oracle.jdbc.driver.OracleDriver,org.gjt.mm.mysql.Driver,org.hsql.jdbcDriver,org.enhydra.instantdb.jdbc.idbDriver</attribute>
</mbean>
Note : First I downloaded the jdriver of weblogic :
mssqlserver4v70rel510sp8.zip and put it into the
director and config the jboss.jcml like up , then
start my jboss server ,but the server give me the info
of “could not load the driver”,then I put the
weblogic.jar and it is ok.
3. connection pool
And then I continue to config the jboss.jcml and
please look below:
<mbean code="org.jboss.jdbc.XADataSourceLoader"
name="DefaultDomain:service=XADataSource,name=SQLServerPool">
<attribute
name="DataSourceClass">org.opentools.minerva.jdbc.xa.wrapper.XADataSourceImpl</attribute>
<attribute
name="PoolName">SQLServerPool</attribute>
<attribute
name="URL">jdbc:weblogic:mssqlserver4:mouse@localhost:1433</attribute>
<attribute name="JDBCUser">mouse</attribute>
<attribute name="Password">99999999</attribute>
</mbean>
4. Then I delete the jboss-auto.jcml file.(when I
config MySQL server,must delete it then it is ok )
5. the results are below when I finish the config and
start the jboss.
