Oracle UDDI Registry Login Issue : 500 Internal Server Error when accessing URL

I recently installed Oracle Service Registry V 10.1.3 on Oracle SOA Suite (with Oracle Application Server 10g R3 10.1.3.2) running on Linux box.

For step by step installation of Oracle Registry (UDDI) Click Here.

Registry application build, including installation was successful and there was no error in  install log of registry ($ORACLE_HOME/log/install.log) .

After restarting (Oracle Application Server/SOA Suite) via opmn (opmnctl stopall; opmnctl startall),  when I tried to access the registry control URL /registry/uddi/web  I received following error:

500 Internal Server Error

 500 Internal Server means “The server encountered an unexpected condition which prevented it from fulfilling the request” to more know about all server status code click here

HTTP Server status code 500 means issue is with application server and nothing wrong with Web (HTTP) Server. It was time to look at application log .

 Registry application was deployed under default OC4J (JVM from Oracle) with name home 

When i checked application.log under  [Oracle AS Home]\  j2ee\ home\ application-deployments\ registry\ home_default_group_1 folder, I got following entries:

CAUSE: Wrong JDBC driver during installation

FIX: Reinstall with new JDBC ojdbc14.jar from here

Re-Installation Steps  

1) Drop the user you created in database for creating repository for UDDI & recreate it

sql> drop user <user_name> cascade;

User Dropped

SQL> create user uddiuser identified by welcome1;

User created.

SQL> grant connect, resource to uddiuser;

Grant succeeded.

2)Undeploy the registry from application server. This can be done via ias console (Enterprise Manager Console).

htp://<hostname>:<port>/em

Click Home : OC4J –>Applications tab –>select registry & click on undeploy tab.

3) Download new ojdbc14.jar from here: here

& replace the jar file under <ORACLE_HOME>/jdbc/lib/ojdbc14.jar with the new downloaded file.

cd  <ORACLE_HOME>/jdbc/lib/

mv ojdbc14.jar ojdbc14.jar_ ori

cp  <downloaded_jar_file_location>  <ORACLE_HOME>/jdbc/lib/

4) Reinstall the OSR, pointing to the new ojdbc14.jar
