MapViewer Demo Returns Blank Maps

I am installing the MapViewer for the first time. I imported mvdemo.dmp after creating the mvdemo user with:
SQL> grant connect, resource to mvdemo identified by mvdemo;
Then import from command line with:
imp mvdemo/mvdemo file=mvdemo.dmp full=y ignore=y
no errors
Then executing sql as mvdemo with :
SQL> @mvdemo.sql
The mapviewer runs the demo and connect to the db as it should. There are base maps, themes, styles etc viewable from the submits.
The image returned however is just a blue tile.
Any ideas where I missed a step?
Thanks

Here is the console output

Mapviewer-demo: a empty map view

Hi,
I imported the Mapviewer demo in a new schema,
and deployed the Mapviewer on stand alone OC4J.
I can start and configure the Mapviewer how described in the guide
without errors but the created JPG is a empty blue picture.
What can be wrong ?
Thanks

MapViewer blank map issue

This is for MapViewer Java API, using tile cache - and it's a hard to reproduce problem
In our application sometimes the map will return blank with no layers. In the logs I'll see that the layers got queried and styles got applied and no apparent errors, but the returned image is blank with only the background color applied.
When this happens just panning around /refreshing will cause the map to be rendered correctly, with minimal wait, as if the cached image was already there created from the previous map request.
Has anyone seen this before ?
Is there something I should be looking for in the logs that could shed some light on the cause of the problem ?
Thanks.

Hi User635830,
firstly I like you "to out yourself" by going to "Your Control Panel" (upper right) --> Your Settings [edit] and edit your "user635830" and insert your name ! Thanks !
Secondly for ur blank map issue I recommend to check the "Java Heap Size" settings, i.e. how much memory is assigned to your Mapviewer Java Application.
Pls see [an explanation how |http://oracle-maps.blogspot.com/2008/05/more-memory.html] in my BLOG.
Hope that solved the problem.

Get Map As XML/Server Image returns blank image on server and errors out on local

In Server, map.getMapAsXML and map.getMapAsServerImage both return blank images though they return a valid url
In local, executing map.getMapAsXML reports the following error:
Uncaught SecurityError: Failed to execute 'toDataURL' on 'HTMLCanvasElement': Tainted canvases may not be exported. oraclemapsv2.js:2171(anonymous function) oraclemapsv2.js:2171(anonymous function) oraclemapsv2.js:2137f

You may be using Windows with limited functionality as the previous version expired. Did you re-format the drive/partition before you did the "fresh" install if not Windows probably kept the old install information so knew that it was expired previously. Either activate Windows (try typing slui.exe and filling in the product key and activate - then restart the machine) or re-format the drive/partition that Windows is on and re-install Windows again.

MapViewer Demo - mapclient.jsp

Hi,
I have installed mapviewer demo on a standalone OC4J. I added a datasource "mvdemo". I can get other jsp's to work: jview.jsp, mapinit.jsp and tagmap.jsp but when I go to mapclient.jsp and enter the datasource field along with Map Center X and Y, I just get a blue blank screen. Do I need to enter anything for Map Base field. Also, I am not getting any error messages.
On OC4J window, I get only message that says "no theme to render".
here is the request:

I do not see basemap in your XML request. You are trying to see entire US extents. Try with smaller size such 1.00.

Help would be appreciated.
-Peter

Try connecting to the database as mdsys.
Look for a table called sdo_geom_metadata_table, and if it is there see if there
is anything in it. If there isn't anything in it, or it isn't there, try executing:
prvtgmd.plb from ORACLE_HOME/md/admin. It looks like the
views might not have been created correctly.

Mapviewer demo v good - are you willing share the cartographic design?

This mapviewer demo is good and has good cartographic design at most levels http://elocation.oracle.com/elocation/ajax/
We are building a Mapviewer applications with the same base map data in Australia. Rather than re-inventing the wheel would the custodians of this web app (Oracle?) be prepared to share the cartographic design elements used here so that we (and I suspect many others) could utilise these to more quickly get their Mapviewer app up and running and looking good?
I think copies of user_sdo_themes and user sdomaps that are particular to this app would suffice - if there is a chance that these could be made available it would be very much appreciated.
Thank you.

We will be staging the current eLocation style and themes up on our MapViewer OTN page shortly.
I will post a point here once we stage them.
thanks
Steve
if you need them sooner email me.

MapViewer cannot process your map request. Check MapViewer log for details.
The log file I found is empty...
Any comments would be helpful!
Thank you a priori

<oms_error>Message:[oms] map data source not found.
Means mapviewer cannot find the data source. If you define the data source from mapviewer admin page, then you need to do it again if you restart the mapviewer. To make it permanent, add the datasource to $OC4J_HOME\j2ee\home\applications\mapviewer\web\WEB-INF\conf\mapViewerConfig.xml.

Mapviewer demo Problem

I have seen a number of posts regarding this issue, but none seem to have solved it. I have installed OC4J, I have installed and imported the mapviewer demo data. I get all of the demos to come up but all I get is a blue screen with the words "Oracle Map viewer Demo" I installed the data with the mvdemo user not as scott/tiger Does that matter? Not sure what else it could be as I am getting no errors anywhere.
Thanks in advance!

TMG always returns blank wpad.dat file on Web Listener

Hello, I have local web server publication on 80 port with redirection to https protocol for local and external clients. And TMG refuses to serve real "/wpad.dat" to clients — instead it serves blank html.
Now I created web publish rule with same Web Listener on 80 port on Internal network that redirects any request with path "/wpad.da*", but while this rule works for "/wpad.dad" and "/wpad.dat?" it doesn't work for "/wpad.dat"!
Why?
I also created simply rule to block access to local "/wpad.dat" url, but it doesn't work either while web listener on next rule is active — TMG still returns blank html.
And when new rules are disabled request to published server for "/wpad.dat" on http protocol returns blank html while it should redirect to https and forward request to real server according to rule configuration. However,
request on https is forwarded to published server.
My configuration requires local web server publication and distribution of wpad.dat file on 80 port, only workaround that i see is to make new server that will redirect requests to wpad.dat file to alternate url.
Thank you for advice on my problem.

Printing to PDF from CrystalReportViewing returns blank page

Hi All,
   I have a web report that I run. When the report generates in the CrystalReportViewer I see my results. However, if I click the button to Print to PDF, it results in a PDF with no data. If I click on the Next button as well to go to the next page in my report, it returns blank results.
This apparently started happening when I used date parameters being passed to my stored procedure:
        parameterField = report.ParameterFields("@callstdate")
        parameterField2 = report.ParameterFields("@callendate")
I'm using VS 2008 and CR2008.
Any ideas why this is happening?
Thank you in advance,

1)Any export type I use returns no data on the exported report
2)Changed PDF to ActiveX and it printed the report with no data
3)Remove parameters from my webapp and let the Viewer prompt for them. Now PDF works and everything else.
Here's my code:
    Protected Sub display_report()
        parameterField.CurrentValues.Clear()
        parameterField2.CurrentValues.Clear()
        parameterField3.CurrentValues.Clear()
        CrystalReportViewer2.ParameterFieldInfo.Clear()
        parameterField = report.ParameterFields("@callstdate")
        parameterField2 = report.ParameterFields("@callendate")
        parameterField3 = report.ParameterFields("Group")
        For Each li As ListItem In Me.ListBox1.Items
            If li.Selected = True Then
                ' Add all parameters value here
                parameterField3.CurrentValues.AddValue(li.Value)
            End If
        Next
        report.SetParameterValue("@callstdate", CDate(st_date.Text))
        report.SetParameterValue("@callendate", CDate(st_date.Text))
        CrystalReportViewer2.ReportSource = report
    End Sub

Queue returns blank strings from template VI

I have created a master VI which creates a named queue, this VI then spawns multiple copies of a template VI. These sub VIs all gain access to the queue and try writing data to it. I understood that the queue VI was protected so this should not cause a problem. Infact this does not work at all, when i extract element within the master VI it only finds a few of the elements and returns blank strings between. Help what is going on. I am not destroying the queue or such, it seems to be a problem with the protection of the queue when using template VIs.
Cheers Tom.

I have not been able to reproduce the problem on LV 6.0.2 Win98. Do you check the error cluster when an empty element is returned? Posting your code might help to find the problem.

Mapviewer/Mapbuilder versus other map serving products

Mapviewer/Mapbuilder versus other map serving products
Oracle Mapviewer is an attractive map serving option for organisations that have large data holdings in Oracle Spatial. Similarly, Mapbuilder is very useful for cartographic assembly of data to be delivered via Mapviewer.
Are other map serving options or cartogarphic tools for web mapping worth considering?
I'd appreciate peoples views/links on how Mapviewer and Mapbuilder compare with other map serving products?
Thanks.

I'd also be very interested to know if using MapViewer gives you better Oracle Spatial performance then with say MapServer (from UMN). Our company has a UMN MapServer setup and we're using some Oracle Spatial data to populate this as well and I see a lot of performance decrease when trying to use Oracle Spatial data. One nice thing about UMN MapServer is the fact that it's free and supports many type of GIS data. There are also quite a few application frameworks available for developing a client front-end. We use Chameleon currently.
I would like to know what other people are using with Oracle Spatial.

Mapviewer demo's

Hi,
I'm trying to get the mapviewer demo's up and running, but I can't find instructions to do this.
Oracle spatial and mapviewer are new to me, so maybe anyone can tell me how to do this.
I've installed oracle 10g database and standalone mapviewer.
I can visualize data from the demo-dataset for user scott.
But when I click (on the mapviewer homepage) on one of the examples my browser gives the usual 'the page cannot be displayed' message.
Do I need to install the demo's in some way, or place the jsp files in a certain directory??

Suggest just doing a search within this forum, that answer has been written about 1000 times. Try this: http://www.oracle.com/technology/software/products/mapviewer/index.html
try the QuickStart Kit and install the Demo's.
This will provide you with all of your answers.
Hope it helps.
