SRM-MDM without EP does not work fine

Dear Experts,

I want to bulit a demo environment based srm 7.0 with sap pi and without sap ep.

Our installed srm-mdm's version is 7.1.05.66.

I imported the srm-mdm java api and srm_mdm_cat business package into the PI as java server using JSPM.

When I turn the web address http://hostname:sap_pi_java_port/SRM-MDM/SRM_MDM, it show ' 500 Internal Server Error'!

The detail is:

Error: "Application error occurred during the request processing."

Details: "The WebApplicationException log ID is [0024E851B45E00B300000000000020A4]."

Could you give us some suggestions, why can not we log on the configuration page of srm-mdm?

Is there some steps missing during configure the as java server, or we must install sap ep and use its as java server?

Thanks a million!

Yours,

Lorry
