Xcelsius returning java.lang.nullpointerexception from QAAWS

system · February 5, 2012, 9:09am

Hi,
over the past week or so, all my Xcelsius dashboards have lost their functionality, with regard to QAAWS. Even creating a new QAAWS, and plugging it into a new dashboards yield this error.
This isn’t the first time this problem is mentioned on these boards (see QaaWS NullPointerException and Xcelsius Java.lang.nullpointerexception error ), but no solution was ever posted.

Is there any way of solving this? or at the very least getting a trace of the error?
I’m thinking that using another client to consume the QAAWS would also be handy for debugging. Any recommendations?

using version 5.4.0.0 of Xcelsius, and 12.3.2005 of QAAWS.

Thanks!

Look here: QAWS from the browser?

Thanks Andreas,
I installed WireShark, and I can see that the request sent by Xcelsius is okay, but the response from the QAAWS contains

<message>
  java.lang.nullpointerexception
</message>

so now I know the problem’s with the QAAWS, but still, no idea how to handle this…

I found that I can also connect Rich Client to QAAWS, and this, too, is returning errors.
In addition, here’s a snippet of stdout.log in my Tomcat55/logs directory, that pertains to this error:

I found that the root cause of this problem was the Tomcat/Temp directory getting clogged with millions of files, used by QAAWS as a cache.
This link explains how to make QAAWS not use a cache, thus not generating these files and avoiding the problem from the start:

Hi Ethan

We are also struggling with the same error for quite some time… but could not resolve it…

Will making

Setting qaaws.cache_dpresult.optim to False

resolved your issue…

Thanks

Hi Guys,

Having the exact same issue with WEBI report blocks published as web services and exposed to Dashboards 4.1 using QAAWS.

I have checked the dsws.properties file and the setting referred to above is set to false.

Would anyone be able to shed more light on this please?

Thanks
Phil

Hi,

Have managed to get round this although not sure how great a solution this is. I found somewhere that if you have multiple QAAWS web services feeding your dashboard and that these come from different blocks on the same page on the same WEBI report then this error appears.

The suggestion was to have a seperate report for each block feeding the Web Service. So in our case I had four web services. All of which came from the same WEBI report on the same page. I split this into 4 WEBI reports each having one block and then published the web service from there.

Have never received this error since. As I say, pretty rubbish solution but it works.

Thanks
Phil

Yeah, we got that line from SAP, too. We have taken the step of not only separating them onto different reports, but actually onto separate documents. It means a lot more objects in our system, but things do seem to be running more smoothly.

I do wish that SAP would either fix the problem (ideally) or at least put a warning in the web service publishing wizard. Because duplicating the objects is not an intuitive solution.
