Troubleshooting
Problem
Attempts to navigate to the project dashboard results in HTTP 400 error with IBM Rational Team Concert (RTC).
Symptom
When opening project dashboards or clicking on the 'About the Application' link in Rational Team Concert, the following error occurs:
An error occurred while retrieving the dashboard:
Unable to load /ccm/proxy?
uri=https://<server:port>/jts/dashboards/2087?contentType=application%2Frdf%25xml status:400
Note: The 'About the Application' displays the status:400 error, but with different URL.
In the ccm.log file, the following error is present:
[ WebContainer : 0] ERROR net.jazz.ajax.service.internal.http.ProxyServlet - GET https://<server:port>/<ccm_context>/proxy
?uri=https%3A%2F%2F<server>%3A<port>%2Fjts%2Fdashboards%2F2087%3FcontentType%3Dapplication%252Frdf%2525xmlHEADER: Host = <server:port>
...
Parameter: uri = [https://<server:port>/jts/dashboards/2087?contentType=application%2Frdf%25xml]
org.eclipse.core.runtime.AssertionFailedException: null argument:The local application's root services could not be fetched, contained invalid content, or was missing the required entry for jfs:oauthDomain
at org.eclipse.core.runtime.Assert.isNotNull(Assert.java:85)
Cause
The following web container's custom properties are missing. These entries are added to force IBM WebSphere Application server to honor host headers.
trusthostheaderport = true
com.ibm.ws.webcontainer.extracthostheaderport = true
Environment
- Distributed CLM environment
- Reverse Proxy configured
Diagnosing The Problem
You can enable the following log4j entry on the CCM server by adding the following entry to log4j.properties and reloading the log settings:log4j.logger.org.apache.http.impl.conn=DEBUG
This will result in the following output in ccm.log:
[ Worker-0] DEBUG org.apache.http.impl.conn.tsccm.ConnPoolByRoute - Creating new connection [HttpRoute[{s}->https://<server:port>]]
[ Worker-0] DEBUG che.http.impl.conn.DefaultClientConnectionOperator - Connecting to <server:port>

Resolving The Problem
Add the following web container's custom properties to force WebSphere to honor host headers:
trusthostheaderport = true
com.ibm.ws.webcontainer.extracthostheaderport = true
