Answer 1

If GlassFish and Oracle Database are installed in the same system, it results in port conflict as both of them use port 8080.

Here is the procedure to change port number of GlassFish so that you can run GlassFish at a different port number from Oracle to avoid the port conflict.

1. Find out the folder where GlassFish is installed.

   If you installed GlassFish along with NetBeans, you can find out the folder where GlassFish is installed by using the following procedure.

    Select Services window by using **Window -> Services** in NetBeans IDE
   
    Expand **Servers** node and select GlassFish Domain
   
    Right click and select **Properties** option from popup menu.
   
   On the right of **Domains Folder** you can see the folder where GlassFish is   installed. 
   For example : 
   C:\netbeans6.8\glassfish-v3\glassfish\domains. You can also see the            other details regarding Glassfish such as port number, in the same window.
   

2. Go to the folder where Glassfish in installed.

3. Go into config folder which is as follows: c:\netbeans6.8\glassfish-3\glassfish\domains\domain1\config

4. Open domain.xml using any text editor.

5. Look for 8080 and change it to some other port number that doesn’t conflict with other port numbers. I generally change it to 9999.

6. Save domain.xml.

7. Now you need to remove GlassFish from NetBeans and add it again so that NetBeans IDE understands the new port number. For this do the following

    In **Servers** window of NetBeans, remove GlassFish by using **RemoveServer** button after selecting GlassFish server.
   
    Click on **AddServer** and select GlassFish V2 or GlassFish V3 and click on **Next**.
   
    Select the **Installation Location** of GlassFish and click on **Next**.
   
   Accept defaults and click on **Finish.**
   

8. Restart GlassFish, if it was already running.
