Analyzer (WebAnalysis) Client not getting loaded – Solution

You may have seen this error while launching WebAnalysis using 16000 port where WebAnalysis client won’t get loaded at all. If you look at Java console it’ll show the below given error.

load: class com.hyperion.analyzer.usersession_base.AnalyzerClient not found.

java.lang.ClassNotFoundException: com.hyperion.analyzer.usersession_base.AnalyzerClient

If you access WebAnalysis using 19000 port it works fine!!!!
I was looking for reasons behind this one and found that 16 jar files and jre-6u22-windows-i586-s.exe are missing from WebAnalysis.ear file!!!!!!
These files are present in <HYPERION_HOME>commonepmstaticwebanalysis folder where as the static folder in WebAnalysis.ear located under <HYPERION_HOME>productsbiplusInstallableApps file doesn’t have them. You can use 7Zip or Winrar to open ear files.
So I tired copying them to the tmp directory of Weblogic server and it worked fine for me after that. Highlighted folder can be different on your environment.
I’m not sure on why it is not present there, maybe someone missed to add the files there or from this release you can’t open WebAnalysis using it’s native port (16000) 🙂
If you are interested in a permenant work around/fix, then you can add the jar files and jre-6u22-windows-i586-s.exe to the WebAnalysis.war file.
Open WebAnalysis.ear file with 7Zip or Winrar
Open WebAnalysis.war file and navigate to static folder
Compare the file present in <HYPERION_HOME>commonepmstaticwebanalysis against static folder and add missing ones.
