Spatial datasource comes with detailed instructions and there was no problem to install it on my Oracle XE (XE supports spatial functionality). When you start Quickstart kit for the first time, Oracle MapViewer deployment process is completed automatically. You can find instructions in Quickstart readme file about how to open Oracle MapViewer homepage and then according to the tutorial - Learning Oracle Maps by Example (it comes with Oracle MapViewer), configure Oracle Maps settings.
So, what about JavaScript? Oracle Maps functionality is reached from JavaScript code, so we need to place a portion of JavaScript somewhere between ADF Faces components. It is quite easy, just include div element for map image and surround it using f:verbatim tag. Script for displaying a map is straightforward (do not forget to include oraclemaps.js, this script comes with Oracle MapViewer).
And, finally we have a map, that displays population density by counties:
With sample application comes deployment profile, which you can use if deploying to Oracle Application Server.
Hi Andrej,
ReplyDeleteas an oracle-maps enthusiast (oracle-maps.blogspot.com) and I tried ur simple example with ADF just incorporating the map and got this error in JDeveloper 10.1.3.1:
java.lang.NullPointerException at javax.faces.webapp.FacesServlet.init(FacesServlet.java:165)
- admittedly I am not a Java guy (rather pl/sql) - what went wrong ?
Any hint wud help.
TIA
Bernhard
Andrej,
ReplyDeleteI solved the error by installing the JSP Tag Lib as indicated as a remark in four of the first lines.

Hi Bernhard,
ReplyDeleteMost probably you have faced this problem, because standard adf-faces-impl.jar and jsf-impl.jar were not available in JDeveloper project lib directory by default. I'm simply removing those libraries when posting samples on the blog, in order to reduce zip archive size. How to add those libraries:
adf-faces-impl.jar should be copied from C:\JDeveloper\jlib to ApplicationName\UserInterface\public_html\
WEB-INF\lib
jsf-impl.jar should be copied from C:\JDeveloper\jsf-ri to C:\JDeveloper\jlib to ApplicationName\UserInterface\public_html\
WEB-INF\lib
If you will have more questions, please post a comment or drop an email. I will be glad to answer.
Thanks,
Andrejus
Hello,
ReplyDeletewhen I run the page I get no output at all , neither any error messages.
Hi,
ReplyDeleteYou should run application from the same server where Oracle MapViewer is deployed. It is not possible (ok, it's possible with some hacking :), just browse Spatial forum on OTN) to have Oracle MapViewer on one server and application with Oracle Maps functionality on another. This is related to JavaScript security issues.
I guess, in your case, you have deployed Oracle MapViewer on Application Server and you are running sample application on JDeveloper embedded OC4J.

Andrejus
Hi Andrej,
ReplyDeleteIs it possible to run this application with a standalone Mapviewer, I mean, like the Faces example that comes with Oracle Mapviewer? I am able to run the sample application on JDeveloper embedded OC4J, but of course, no map is rendered as Mapviewer is not in the same server...
Hi Francisco,
ReplyDeleteYes, it is possible. You just should use Quickstart kit for MapViewer. It comes with standalone OC4J, this means you can deploy on it your application.

Andrejus
Andrejus,
ReplyDeletethank you very much for you useful blog.
I am tried run Oracle MapViewer on one server and application with Oracle Maps functionality on JDeveloper embedded OC4J. I could not achieve success. What did you mean "This is related to JavaScript security issues." Maybe I should special configure OC4J with MapViewer?
Thank you very much.
Sergey Malinin.
Hi Sergey,
ReplyDeleteYou can run Oracle Maps application only on the same server where Oracle MapViewer is deployed. Oracle Maps functionality is implemented with JavaScript, its not possible to access server side Oracle MapViewer, deployed on separate server.

Andrejus
I am trying to run the mvdemo.dmp for exporting data and i am getting the folowing warning
ReplyDeleteThe statement i used to run this dmp is

Is there any other way i can run the mapViewer on any other database which has by default all the data?

Hi,
ReplyDeleteYour database should have MDSYS schema installed. This schema comes with Oracle XE database. Basically, you need to have Oracle Locator package in your database.

Andrejus
Hi,
ReplyDeleteI did everythig you said and deployed in standalone OC4J that contains mapviewer but now i can't figure out which URL to use to run application
Thnx in advance,
Alexandra
Hi Alexandra,
ReplyDeleteYou can open OraMapsSimple.deploy file in JDeveloper, in General section under J2EE Web Context Root there is specified - oramapsimple.
Complete URL will be: http://host:port/oramapsimple/faces/map.jspx

Hello Andrejus,
ReplyDeleteI am getting the same error while importing MVDEMO.dmp as Suman has reported in his comments.
IMP-00060: Warning: Skipping table "ORA04110"."CITIES" because object type "MDSYS"."SDO_GEOMETRY" does not exist or has different identifier.
I have verified that the MDSYS schema exists in the database and i can describe SDO_GEOMETRY type.
Also, i am able to create a table which has a spatial column (using SDO_GEOMETRY). Not sure why the import does not work and throws the error on SDO_GEOMETRY.
I am on database 11g.
Any help in this regard is much appreciated.
Thanks,
Nitin
Hi,
ReplyDeleteIt can be something specific to 11g, I suggest to check on OTN forum for Spatial group.
Regards,
Andrejus
Hi
ReplyDeleteI'm having the same issue as Nitin (two comments above). I'm also on 11g. I couldn't find anything related to this on the Spatial forum so have posted there as well.
If anyone has successfully imported the mvdemo.dmp file into an 11g database then please let us know!
Cheers
Richard
I got a reply from the OTM Forum regarding the 11g installation problem. The answer is to disable validation on the SDO types by setting parameters on the 'imp' command line:
ReplyDeleteimp .... file=mvdemo.dmp TOID_NOVALIDATE=MDSYS.SDO_GEOMETRY,MDSYS.SDO_ELEM_INFO_ARRAY,MDSYS.SDO_ORDINATE_ARRAY
It worked for me.
(Thanks to Siva)

Hi Andrejus,
ReplyDeleteGood see your posts. I wanted to get world map. How one can create spatial data for world map.
Also explain me with querying non spatial data when I click a particular place.
Awaiting for your response.
