Is my SAP using J2EE engine?

[Former Member]

Hi Experts,

Any idea how to tell for sure if J2EE is installed in addition to Abap stack?

Take a look at this "link" on your installation.

http://<yourhost>.<yourdomain>:<yourport>/sap/monitoring/SystemInfo.

and you will get a very useful overview of your installation.

Under the list of software components you should see SAP-JEE.

Hope this gave you some useful information.

Hi Ernesta

Run following URL

http://<FQDN>:50000

If it is working then in your system J2EE engine is installed and it is functional.

You can check from transaction SMICM.

You can also check database for j2ee engine tablespace, name of j2ee tablespace is PSAP<SID>DB.

Dear Experts,

Thanks for your useful info. Points set for your help.

I wonder if I can still install J2EE engine onto my central system. Or I can only have J2EE by re-installing?

Eg. in future when I need to integrate with the said J2EE applications from SAP?

I can always install J2EE as addon option to your existing instance.

One way , look for /usr/sap/<SID>/D<instance>XX/j2ee

If there is a j2ee folder then you have j2ee already installed.

Thanks Aditi !

Why do people use J2EE engine?

My BW central instance is not installed with J2EE engine. Can I still install a J2EE Dialog instance to talk with central instance not J2EE-installed??

Can I still J2EE-enable my BW central instance?

Any impact of not installing with J2EE engine for dialog instance?

Best regards,

Some SAP applications are developed using J2EE (Some of the platform components e.g. EP, XI etc also use J2EE). If you plan to use these applications or platform components you can install J2EE otherwise there is no need to install it.

Some application like EP have to have J2EE installed and some are not. You can always install J2EE as an Add java to any component . There is no impact on not installing J2EE on dialog Instance.

If you are planning to have largescale development using J2EE then you also can have standalone development environment using J2EE and eclipse IDE.

Thx,
