Twitter Adapter - JDBC error 403 - cannot find remote source: proxy

[Former Member]

We are currently exploring SAP HANA Smart Data Streaming and have followed videos on SAP HANA Academy for getting started with the Twitter adapter.  When we get to the point to test the connection from creating a new Remote Source we receive the following error:

SAP DBTech JDBC: [403]: internal error: Cannot get remote source objects: proxy

Our IT Admin had the following comment:

If both the HANA and Agent systems are on the same LAN w/o a firewall between then, then there shouldn't be a need for a proxy. 

My questions:

Is there a way to get the Twitter Adapter to work with SAP HANA Smart Data Streaming that does not require a proxy to be setup?

If a proxy is required at all times to use this functionality, what is the reasoning.

Update for resolution

(2) steps required to get this working without requiring a proxy

1.  Change your TWITTER DEV account time-zone to the following setting:

(GMT) UTC

2.  Change the dpagentconfig.ini for the Data Provisioning Agent:

The ini file by default has the following:

• proxyHost=proxy
• proxyPort=8080
• proxyType=

Changing the ini file with following allowed a successful test connection:

• proxyHost=
• proxyPort=
• proxyType=

Hi Jonathan ,

i'am nearly facing the same issue like you with the twitterAPI.

This is my error msg:

SAP DBTech JDBC: [403]: internal error: Cannot get remote source objects: connect timed out

I tried to reproduce the steps you posted, but i cant change the Timezone in Twitter to utc gmt.

Any other tipps to get this working?

HANA smart data streaming does not come with a Twitter adapter.  I assume you are using the Twitter adapter for HANA smart data integration and following the HANA academy videos for that.  That adapter will let you capture Twitter data in HANA tables, but doesn't currently support HANA smart data streaming.

Correct, used the incorrect term.

If there is a different blog area for that question please let me know, but in SAP HANA smart data integration for the twitter adapter, is it required that there must be a proxy or can we accomplish this without a proxy?

Hi Jonathan,

I believe that the site for you to use for HANA Smart Data integration questions is

Hi Alice,

Have not received any feedback on this in the HANA Developer Center, any ideas?

Thanks,

Hi Jon,

The only other idea I can come up with is for you to log an incident with SAP Support. Here is the link: Report an Incident | SAP Support Portal
