I'm using following versions.

  • SDL Web 8
  • DXA 1.4

I set up following services. PageContentFilter and BinaryContentFilter are disabled in web.xml, so Preview service is not used.

  • Discovery
  • Content
  • Context
  • Deployer

Error occurs when requesting DXA page (/index.html), probably Context Service causes the error.

I download Context Engine's repository (I contacted SDL support to add my server's IP to white list), and put it into Context and Content Services.

Context Service's URL is http://10.0.1.98:8087/context.svc. When requesting the URL by wget command, Context Service output debug log, so it's running surely.

But requesting DXA page (/index.html) URL, Context Service does not output any debug log, so I guess Context Service is not called.

There is no error log in Context Service itself, Discovery and Content Service.

My questions are following.

  • There is a step "Installing the Context Service client", in SDL Web 8's manual. Is the step required on DXA 1.4?
  • My Discovery service's Role setting of Context Service correct?
  • Is there any possible configuration failure?
  • Is it possible to disable using Context Service on DXA?

  • I noticed a more recent question from you about changing XPM CM URL. Does that mean that you managed to solve this problem? If so, can you let us know how you solved it?

There is a step "Installing the Context Service client", in SDL Web 8's manual. Is the step required on DXA 1.4?

No, the context client is part of the DXA framework and doesn't have to be installed separately.

My Discovery service's Role setting of Context Service correct?

Looks OK to me.

Is there any possible configuration failure?

Always. :-) What springs to my mind: Discovery Service URL and OAuth credentials have to be configured in cwd_client_conf.xml (as well as in cd_client_conf.xml).

Is it possible to disable using Context Service on DXA?

Yes, you can use the ADF Context Claims Provider, which expects the Context Claims to be in the ADF (this requires the use of the Context Engine cartridge in your Content Service. This is known to perform worse than direct access to Context Service, but it's worth a try if you're encountering problems with Context Service access). See http://docs.sdl.com/LiveContent/content/en-US/SDL%20DXA-v4/GUID-9127A28E-5DF8-45C9-B64D-2EC2C5280195

BTW: DXA 1.5 has recently been released. This uses CIL 8.2, which incorporates earlier CIL 8.1.1 hotfixes. Makes sense to try if that gives you better error handling.

DXA 1.4 worked by changing JVM_OPTIONS in start.sh of SDL Web 8's microservices. 

JVM_OPTIONS="-Xrs -Xms256m -Xmx512m -Dorg.apache.tomcat.util.buf.UDecoder.ALLOW_ENCODED_SLASH=true -Dorg.apache.catalina.connector.CoyoteAdapter.ALLOW_BACKSLASH=true"

I got this from following post.

Web 8 DXA 1.5 Java web site failing with "Unable to get response from OData service"
