Today I was helping a customer on a deployment issue…
The first question that I have asked is:
“Which version of OC4J are you using ?”.
And he has no idea !
So let me give you some tips to know the version of Oracle components that you are using…
In the j2ee/home directory:
java -jar oc4j.jar -version
Go in the provider test page
You can see the version of the in the bottom of the page. In the JPDK you can also use the
HttpCommonConstants.COMPONENT_VERSIONS to access it programmatically.
Also if you are looking for a version of a specific component, Oracle development often use a ‘version file’ into the jar file of this component.This is the case for example for:
- Portals: ptlshare.jar, wsrp-container.jar, wsrp-container.jar, pdkjava.jar, portaltools.jar
- Oracle XML: xmlparserv2.jar,oraclexsql.jar, xsqlserializers.jar
- UIX: uix2.jar, jewt4.jar
- BI Bean: bigraphbean.jar
Update following Markus comments:
Markus made me realized that I forgot to mention the standard way of checking the version of a product. It is also possible, and done by most of the Oracle components, to put the version number into the Manifest file of any archive. So take a look to the manifest, and if it is not available you can look for a version file into the archive.
So next time somebody ask you which version of the product you are using you will be all set !
