Which Version I Am Running ?

| Comments

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 !
