ISession context

[#1]

Hi experts,

I often got this error message as Isessioncontext.

The error summary is:

Hi Hari:

Not sure about the NWDS Versioning part, but check whether your WebDynpro Machine (the NWDS installed machine) has the following JAR at the said location.

<u>(Drive):\Program Files\SAP\IDE\IDE70\eclipse\plugins\com.tssap.dtr.client.vfs_2.0.0\<b>httpclient.jar</b></u>

The directory structure may be different, because of different versions of WD. You can also simply search with <b>httpclient.jar</b> and place it in the WD Project Libraries and Run/Delpoy, hope it may solve your problems.

Tnx,

MS.
