Hibernated Pojo Generator using config.xml for Oracle database

[rama ganti]

Please specify how to work with Hibernate Pojo Generator .

I have a hibernate dependancies jar file and i have created a config.xml file.

My database is Oracle

My config.xml has the following code

<?xml version="1.0" encoding="ISO-8859-1" ?>
<appconfig>
<dbType>Oracle</dbType>
<driver>sun.jdbc.odbc.JdbcOdbcDriver</driver>
<url>jdbcracle:thin:@ 192.168.64.137:1521:XE</url>
<username>scms</username>
<password>scms</password>
<sourceTarget>C:\workspace\TEST_POJ</sourceTarget>
<projectName>TESTPOJ</projectName>
<topLevel>JMBAXI</topLevel>
<libPath>libs</libPath>
<schemaStrategy>FULL</schemaStrategy>
</appconfig>




When I am running the code through command prompt I am getting a null pointer exception

Thanks for editing the original post to add the stack trace etc... But you also can add a reply instead modifying the original post.

To your question you have to check for those jars missing and add them to the classpath.

Couldn't find class org.apache.velocity.runtime.log.AvalonLogChute or necessary supporting classes in classpath.

[Vijitha Kumara]

Hi Swapnil Kadu,

Welcome to the CodeRanch!,

What kind of application/environment is this (TellTheDetails)? Is this same as the Original poster's?

And what is the implementation in the code this exception is relate to (CaseInsensitiveComparator.java)?

[Swapnil Kadu]

Hi Vijitha Kumara,

application/environment is same as the Original poster's.

i want to use Hibernate pojo generator for Oracle Database, but when I use for Oracle db it shows above err.

but Hibernate pojo generator works fine for MySql.

is there any step i may forgot ?
please let me know!

[Vijitha Kumara]

Can you show the code related to the above (as I asked in the previous reply) with the relevant configuration? And also with the steps you follow...
