VO Substitution - methods

Question

Hi,
Can any one explain the methods involved in VO substitution. I would like to know if JPX Import Command is mandatory for a VO substitution. In one of the articles I read, it just mentions about substituting a VO (jpx file creation) but no where I came across the import command.
I would like to know if a VO extension can happen without this.
Thanks,
Padmaja

Hi Cornell,
You need to Import Jpx file and need  to bounce apache for change effect.
Please check below steps for more understanding.
Deploying Your ViewObject Extensions
Deploying Your ViewObject Extensions
Step 1:  Compile your Java in JDeveloper and copy ur .xml and .class files to Server
            <$JAVA_TOP>/<CompanyIdentifier>/oracle/apps/<AppsProductShortName>/server (BC4J files)
            so, if you extend a "so" view object, and your company's name is "xyz," a subclass of the Ordervompl
              view object would be in the following directory:
             <$JAVA_TOP>/xyz/oracle/apps/so/server/xyzOrderVOImpl.class
             Set the permissions on $JAVA_TOP/
Step 2:  Copy the .jpx definition file to the Top.
              In my case I have creataed JpxFile Folder on JAVA_TOP  and Copied my .jpx file there .jpx file,
              which should be located under <JDEV_USER_HOME>\myprojects, to the following   staging area:
               $JAVA_top/JpxFile/
Step 3:  Run the jpx import utility from JAVA_TOP to import substitutions specified in the .jpx definition
              file to the MDS repository.
              The import utility, jpximport.bat or the jpximport shell script. You run this utility from the command
              line  by specifying:
              A. The database credentials of the MDS repository on your target instance
              B. The fully-qualified location of your .jpx file, which should be located under
              $JAVA_top/JpxFile/
            Using the example on substituting the OrderVo view object from  Order.jpx, your command line
             would look something like the following:
            java oracle.jrad.tools.xml.importer.JPXImporter $JAVA_TOP/xyz/jpxFiles/Order.jpx \
           -username <apps username> \
           -password <apps password> \
          -dbconnection "(description=(address_list=(address=(community=tcp.world)(protocol=tcp)
           (host=<Host Name>)        (port=<PortNumber>)))(connect_data=(sid=<SID Name>)))"
Step 4: Bounce the web server
step  5: Do Personalization If Required
Step 6: Review your deployed extensions
   At this point the deployment of your extension is complete, and you should be able to login to your
   application to verify that your changes have successfully taken effect.
   You can check you Extension Using JDR_util Package
