The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Why is WLST throwing a File Not Found Exception when the file is there?

Asked by Bbouch in BEA WebLogic Application Server, Java Programming Language, Python Scripting Language

Tags: , , ,

I have a WLST script (jython) that is supposed to import a jar into an Aqualogic Data Services Platform (3.0) cluster running on Weblogic 9.2 MP2.

The script is able to connect to the adminServer, and create an edit session, but when it trys to import the jar, it gets an error that seems to indicate the Jar it is trying to import is not found.  The jar is in the same directory as the script, so I am not sure what the problem is.

In all fairness, though, I am releatively new to Jython, and scripting, so its possible I am not reading the results accurately.  If anyoe has thoughts on why I may be receving this error, I would love to hear them.

The line that the script is failing on is:
    wlst.invoke('importJar',[dataspaceName,importJarFilePath,deploymentOptions],['java.lang.String','java.lang.String','com.bea.dsp.management.deployment.session.DeploymentOptions'])

I have already echoed out the variables being used, and they seem ok, so I'm stumped on where to go from here.
