Error - Algorithm doesnt exist, while describing process

Girija Kalyani
Configuration:
OS- Windows-32 bit
Version: WPS-3.3.0 wepapp.war
Running through eclipse
Here's my wps_config and wps-geotools-config files attached.
Log files are also attached.
When run using debug mode, eclipse console shows- successfully built.
Able to execute "GetCapabilities request"
Rscript got deployed
 Described Process using : "http://localhost:8080/wps/WebProcessingService?Request=describeProcess&Service=WPS&Identifier=org.n52.wps.server.r.RandomNumbers&version=1.0.0" which shows error -Algorithm does not exist: org.n52.wps.server.r.RandomNumbers
And then, when i go to "http://localhost:8080/wps/test.html", i cant see my r-script being deployed.
Thanx in advance

Only the wps_config.xml is actually used. Please rename it to
wps_config.xml_backup and rename wps-geotools-config.xml to
wps_config.xml. WPS4R requires GeoTools and all the configuration
parameters that can be found in wps-geotools-config from line 598 on.

Hope this helps.

Wow, Thanx a ton Mr.Daniel.It worked.!!! I changed the wps-config files names as you suggested and its working.. :)
Thank u so much for baring me with patience
Now, I test it using test.html, pasted the xml code and i get error "There went something wrong with parsing the POST data: The processing instruction target matching "[xX][mM][lL]" is not allowed."

Can you please clarify? WHAT EXACTLY is working? Can you run
GetCapabilities?

Which process, what is the exact XML that you submit via the form?

Re: Error - Algorithm doesnt exist, while describing process

Girija Kalyani
Dear Daniel,

When I renamed the wps_config_geotoolsto wps_config, i can see the R-repo being loaded, but then when i re-start afresh, the wps_config_geotools renamed for wps_config is changing automatically to its original value. How can this happen?
And the deployment of the R-script is shown (that was what I referred to as working)
But, the describeProcess part is still a problem, I have given another r-script too and it doesnot detect, could it be that the algorithms aren't getting saved at right place?
Bcause I get same error most of the time specifying "Algorithm doesnot exist".
After deploying R-script, what I did was,
Go web-Admin-console, GetCapabilities req(URL-default one), and I cannot view any of the R-scripts here, just the default ones are seen.
Even then I proceeded, to DescribeProcess using URL request, and it shows 
<ows:ExceptionText>
Algorithm does not exist: org.n52.wps.server.r.test.mytrial
</ows:ExceptionText>
</ows:Exception>

And the error I find at backend (in my eclipse console)is: 
WARN  org.n52.wps.server.request.Request: Parameter <language> not found.
DEBUG org.n52.wps.server.WebProcessingService: org.n52.wps.server.ExceptionReport: Algorithm does not exist: org.n52.wps.server.r.test.mytrial

Finally, to Execute the process I have initially copied the XML code from the tutorial, but now, had gone through the link specified about XML spaces, and still nothing works.
:(

I don't know. What do you mean with "re-start afresh"? The files should
stay the same when you restart the tomcat, but if you re-install the
webapp they obviously are replaced with the ones from the new installation.

Do you save them at the same location as selected in the wps_config file
under the attribute "R_scriptDirectory" ?

If a process is not listed in the capabilities, then DescribeProcess
will never work.

Have you tried saving the script directly in the folder defined in
R_scriptDirectory?

Without the process being listed in the Capabilities, there is no need
to execute it because that can never work.

I hope some of my questions above can help.

Re: Error - Algorithm doesnt exist, while describing process

Girija Kalyani
Yeah Mr.Daniel, you exactly answered what I want. Thanx for that.
And I followed as directed by you, I have checked the web-app, and re-installed evrything in sequence and it no more changes after restarting tomcat. 
Problem was with the war file i deployed.
Secondly, yes, i have checked my wps_config file's R_scriptDirectry, it points out towards my web-app's R/scripts/ , and i have manually deployed in this folder but cannot view in the capabilities list. 
Thanx in advance sir

Dear Daniel,

When I renamed the wps_config_geotoolsto wps_config, i can see the
R-repo being loaded, but then when i re-start afresh, the
wps_config_geotools renamed for wps_config is changing automatically to
its original value. How can this happen?

I don't know. What do you mean with "re-start afresh"? The files should stay the same when you restart the tomcat, but if you re-install the webapp they obviously are replaced with the ones from the new installation.


And the deployment of the R-script is shown (that was what I referred to
as working)
But, the describeProcess part is still a problem, I have given another
r-script too and it doesnot detect, could it be that the algorithms
aren't getting saved at right place?

Do you save them at the same location as selected in the wps_config file under the attribute "R_scriptDirectory" ?


Bcause I get same error most of the time specifying "Algorithm doesnot
exist".
After deploying R-script, what I did was,
Go web-Admin-console, GetCapabilities req(URL-default one), and I cannot
view any of the R-scripts here, just the default ones are seen.

Even then I proceeded, to DescribeProcess using URL request, and it shows
<ows:ExceptionText>
Algorithm does not exist: org.n52.wps.server.r.test.mytrial
</ows:ExceptionText>
</ows:Exception>

If a process is not listed in the capabilities, then DescribeProcess will never work.

Have you tried saving the script directly in the folder defined in R_scriptDirectory?


And the error I find at backend (in my eclipse console)is:
WARN  org.n52.wps.server.request.Request: Parameter <language> not found.
DEBUG org.n52.wps.server.WebProcessingService:
org.n52.wps.server.ExceptionReport: Algorithm does not exist:
org.n52.wps.server.r.test.mytrial

Finally, to Execute the process I have initially copied the XML code
from the tutorial, but now, had gone through the link specified about
XML spaces, and still nothing works.
:(

Without the process being listed in the Capabilities, there is no need to execute it because that can never work.

I hope some of my questions above can help.

Re: Error - Algorithm doesnt exist, while describing process

Girija Kalyani
Sir,
The problem here seems to be, that wps isn't recognising R scripts, because i can see LocalAlgorithm's default algorithms shown in capabilities script but none of R-scripts are shown.
I have tested Rserve connection too, it seems to be working fine.
I really don't get what could be the error sir.

Ok - just to be sure please double check in the log files that the
Local*R*AlgorithmRepository is loaded during startup of the service.
This happens if it is activated in the wps_config.xml file.

You can also set the log output to debug and attach the output again here.

To make sure you're not having problems with the config file again, you
can also try to set u one of the other configuration mechanisms [1].

Re: Error - Algorithm doesnt exist, while describing process

Girija Kalyani
Sir,
Yeah what you said was right. on startup, i cannot see LocalRalgorithm registered.
But i hav follwed the link you suggested, customised the startup and though it doesnot show up while starting, it seems to be loaded when I check for webAdminconsole. I can view my R_repo and the added scripts.
Here is the attached log file.
This file just shows that LocalAlgorithm is loaded, along with servicerepository but not R-repository.
But I have given the path to file file as suggested sir.

because i can see LocalAlgorithm's default algorithms shown in
capabilities script but none of R-scripts are shown.

Ok - just to be sure please double check in the log files that the Local*R*AlgorithmRepository is loaded during startup of the service. This happens if it is activated in the wps_config.xml file.

You can also set the log output to debug and attach the output again here.


I have tested Rserve connection too, it seems to be working fine.
I really don't get what could be the error sir.

To make sure you're not having problems with the config file again, you can also try to set u one of the other configuration mechanisms [1].

    Yeah Mr.Daniel, you exactly answered what I want. Thanx for that.
    And I followed as directed by you, I have checked the web-app, and
    re-installed evrything in sequence and it no more changes after
    restarting tomcat.
    Problem was with the war file i deployed.
    Secondly, yes, i have checked my wps_config file's R_scriptDirectry,
    it points out towards my web-app's R/scripts/ , and i have manually
    deployed in this folder but cannot view in the capabilities list.
    Thanx in advance sir

            Dear Daniel,

            When I renamed the wps_config_geotoolsto wps_config, i can
            see the
            R-repo being loaded, but then when i re-start afresh, the
            wps_config_geotools renamed for wps_config is changing
            automatically to
            its original value. How can this happen?


        I don't know. What do you mean with "re-start afresh"? The files
        should stay the same when you restart the tomcat, but if you
        re-install the webapp they obviously are replaced with the ones
        from the new installation.


            And the deployment of the R-script is shown (that was what I
            referred to
            as working)
            But, the describeProcess part is still a problem, I have
            given another
            r-script too and it doesnot detect, could it be that the
            algorithms
            aren't getting saved at right place?


        Do you save them at the same location as selected in the
        wps_config file under the attribute "R_scriptDirectory" ?


            Bcause I get same error most of the time specifying
            "Algorithm doesnot
            exist".
            After deploying R-script, what I did was,
            Go web-Admin-console, GetCapabilities req(URL-default one),
            and I cannot
            view any of the R-scripts here, just the default ones are seen.


            Even then I proceeded, to DescribeProcess using URL request,
            and it shows
            <ows:ExceptionText>
            Algorithm does not exist: org.n52.wps.server.r.test.__mytrial

            </ows:ExceptionText>
            </ows:Exception>


        If a process is not listed in the capabilities, then
        DescribeProcess will never work.

        Have you tried saving the script directly in the folder defined
        in R_scriptDirectory?


            And the error I find at backend (in my eclipse console)is:
            WARN  org.n52.wps.server.request.__Request: Parameter
            <language> not found.
            DEBUG org.n52.wps.server.__WebProcessingService:
            org.n52.wps.server.__ExceptionReport: Algorithm does not exist:
            org.n52.wps.server.r.test.__mytrial


            Finally, to Execute the process I have initially copied the
            XML code
            from the tutorial, but now, had gone through the link
            specified about
            XML spaces, and still nothing works.
            :(


        Without the process being listed in the Capabilities, there is
        no need to execute it because that can never work.

        I hope some of my questions above can help.
