Errors running JCORBA demos in OAS 4.0.7

Hello!!
I am having problem trying to run the JCORBA demo provided with OAS 4.0.7 as well as the example laid out in the tutorial that is provided in the documentation that comes with it.
This is the error I'm getting when trying to execute any of the applications:
oracle.oas.jco.ObjectFactoryException: Cannot locate Resource Manager ; nested exception org.omg.CORBA.NO_IMPLEMENT[completed=MAYBE]
Does anybody have any idea what;s going on here?
Thanks,
T.

The exact adress is ftp://oracle-
ftp.oracle.com/server/patchsets/internet/NT/oas40710/export/
Hope this helps!

File Not Found Error running JSP demos

I'm not sure what is going on, but it appears that every time I try to run a jsp, the server looks in the document root where it errors out with a file not found error. I've seen others with this type of problem but I haven't seen a solution. Anyone have any ideas?
Thanks.

1: Double check the port number that your Tomcat Server is using. (TOMCAT_HOME/conf/server.xml).
2: check you IP. This is not the 'localhost' IP (not sure if it is LAN or real IP). So it may change dynamically.
3: Check for Firewalls. Also, since you are not using localhost, you will have to make sure you traverse all the firewalls built around your system. If you have a router (home), windows XP, or some other firewall, make sure the appropriate ports are opened. If you are behind a corporate firewall, or your ISP closes ports... your kinda out of luck until you find a way to cheat around them.
2: Try just using just "/ValidateUser.jsp" as long as it is one the same domain as the Form. This will make it less likely to break, should your IP change.

Error when run sqlj demo CODE.

I am using JDeveloper 3.0 to run some SQLJ demo codes. The code come with Oracle 8i for NT.
When running these code at first, I did not have any problem. I got all the result correctly.
But after I reboot my computer in the night, and restarted it this moring, I got the error message:
Error running the example: java.sql.SQLException: profile ExprDemo_SJProfile0 not found: java.io.InvalidClassException: [Ljava.lang.Object;; Serialization incompatible with Externalization
I did see the created *.java file and *.ser files in the directory which I set as the source directory and ot path in the Project.
So I am sure tha the translator works, but why Java cannnot find the profil?
I am learn SQLJ. I appreciate any one can help me figure this out.

When you go to the download section to download a SQLJ translator, you will be sent to the JDBC/SQLJ download page.
There you can get the SQLJ 8.1.6 SDK patch which you can use to update JDeveloper 3.0 (essentially, you replace the SQLJ translator.zip file with a new version). This permits SQLJ to function under JDK 1.2.
Additionally, you need to ensure that the environment under which you compile (1.1 vs. 1.2) and under which you run correspond. - Specifically, ensure that you start JDev under 1.2 and that your project also is a 1.2 project. Otherwise all sorts of strange things appear to happen (even with the patch).

Error running the PL/SQL consuming web services demo

I downloaded and installed the PL/SQL code from:
http://technet.oracle.com/tech/webservices/htdocs/samples/dbwebservice/DBWebServices_PLSQL.html
on Oracle 9i version 2 (on both Windows and Solaris) which can be used to consume simple web services. However, I got the following error running the local time demo:

ORA-06512: at "XN.DEMO_SOAP", line 84

It appears to occur upon doing this:

It seems to mean eith resp or resp.doc is null. BTW, the following:

works fine, so does the web service URL. Please
help me get this work!

Error running demo PL/SQL consuming web services

I downloaded and installed the code from:

on Oracle 9i version 2 (on both Windows and Solaris).
But I got the following error running the local time

Can anybody tell me what I do wrong? Thanks a lot!
Also, is there any alternative ways to consume web services
using PL/SQL only? Many thanks!

Mike,
Thanks so much for your help. I tried your code just now.
Same error:
ORA-30625: method dispatch on NULL SELF argument is disallowed

Let me post the code I am using. Note that
I removed the code for using proxy in time_service.

Running the demos problem...

Hi guys!
I'm a newbee in the Mapviewer forum and unfortunately I've a problem with running the mvdemo demos. I've ofc dployed mapviewer in the OC4J, imported the dmp file into scott schema, configured the mapviewer data source...but everytime I'd like to run a demo i receive the unpleasant warning = "No base map MV_DEMO.DEMO_MAP found...". I don't really know where to seek for the solution, because the Mapbuilder is able to see these Base Map ;/ Please help...
With regards,

Similar problem here. I'm running: Windoze Server 2003 , Ver1033p5_B080908, OAS 10.1.3.1. The sever is a static IP. My admin console can't see my cached maps. I can see them in mapbuilder fine so I know the database is up. I know the user_sdo_cached_maps is configured, the data is there and the schema is set up. I have the datasource configured in my mapViewerConfig.xml and I have tried to manually create a datasource.
When I do it manually I get ...
...so I log in to OAS and do a good faith restart of mapviewer so I can test it one more time and fill in the error message, which was MAPVIEWER 0000011 or something, and boom there are my tile layers.
I have no idea what I did. I swear I've restarted mapviewer several times during this process and have no idea why now my tiles are there.
This morning I changed my logging level and did a save & restart option from the mapviewer console but only when I bounced the application server did these finally show up.
One thing that did happen to me during set up was my default tilecache path didn't exist. Perhaps that was the problem? I doubt just turning on loging would "fix" anything. Is restarting the application container for mapserver different than "save & restart" from the mapviewer management console?
Anyhow I'm happy to have tiled maps working :)

I think, that you have compiled you classes with
Jdk1.4+.
To eliminate the problem you can use:
javac -target 1.3 -source 1.3 .....I compiled it with Jdk1.4.x and there's no problem with that. it ran well, I think it's true that the problem is in the classpath.

I take it a simple webutil form with something like CLIENT_GET_FILE_NAME works ok?
If so, then maybe its worth doing a Ctr Shift K and recompile the demo ad try again.

Running AOS demo problems. Please help...

I have installed OAS 4 on my win nt 4.0 with iexplore 4 (5 won't
work by the way) and install the demo applications, but when I
run it, it does not output anything from the Oracle database.
Is there any bug that I should know, or any cartrix that I have
to add before running the demo? Thanks for any help.

IE4.0 does not support XML as it is. You'll need to add XML Parser to IE4.0. It was available from MS site.
I have IE5.0 working with NT4.0 SP5 and with OAS4.0 so it does work.
If you're trying to use XSQL servlet, IIS4.0 does not support JDBC. You'll need to add some software like JRUN.

How run SQLJ DEMO code on JDeveloper 3.0?

I have problem runing the DEMO SQLJ codes. The codes come with the Oracle 8i for NT. I rtried to run them on Jdeveloper3.0 using JDK1.2.
I opened an empty project, and set the source path, out directory, and html path to oracle8i/sqlj/demo, which is the directory of all the demo codes. I also added the SQLJRUNTIME libraries to this project.
After I opened the SQLJ file into the project, I could run the file. I could also see that all the *.java, *.class, and *.ser files were created in the same directory. I assume that the SQLJ translator works. However, I got this error message instead of the results:
Error running the example: java.sql.SQLException: profile ExprDemo_SJProfile0 not found: java.io.InvalidClassException: [Ljava.lang.Object;; Serialization incompatible with Externalization
I am learning sqlj and JDeveloper. I appreciate any help.
Thanks.
Pam

Pam,
(from the Release notes)
Using SQLJ under JDK 1.2
The 8.1.5 SQLJ version distributed with this release of JDeveloper only supports JDK 1.1.X, it does not run under JDK 1.2. A future version of SQLJ will support JDK 1.2.
There are some more useful tips in the release notes. I'd recommend checking them out.
Also, as an FYI: The 8.1.5 JDBC and SQLJ samples can also be found under <jdev>/jdbc/samples and <jdev>/sqlj/demo respectively.
Regards,
Arun

I have a triple boot set up with XP, Archlinux and Ubuntu Lucid on it and I have no problems running YouTube in fullscreen or running xscreensaver-demo or playing Armagetronad in Ubuntu and have no problems in XP either, so it's definitely not a hardware issue.

Error running 9i reports from forms.

Hi folks,
i am having problems running 9i reports from a form.
i have installed Oracle 9iDS on a Win XP machine with 256 MB RAM and a Pentium 1.4Ghz processor.
i also have a local Oracle 9i database. i have created several reports that i am trying to run from some forms but all efforts to date have failed.
below is some sample code.
declare
v_rid report_object;
v_rjob varchar2(100);
v_rptstatus varchar2(100);
v_jobid varchar2(100);
BEGIN
/*get handle to report object itself*/
v_rid := find_report_object('pbranchlist');
set_report_object_property(v_rid,REPORT_EXECUTION_MODE,BATCH);
set_report_object_property(v_rid,REPORT_DESFORMAT,'htmlcss');
set_report_object_property(v_rid,REPORT_DESTYPE,'CACHE');
set_report_object_property(v_rid,REPORT_SERVER,'repsrv');
set_report_object_property(v_rid,REPORT_COMM_MODE,synchronous);
v_rjob := run_report_object(v_rid);
v_rptstatus := report_object_status(v_rjob);
while v_rptstatus in ('RUNNING','OPENING_REPORT','ENQUEUED') loop
     v_rptstatus := report_object_status(v_rjob);
     message(v_rptstatus);
end loop;
if v_rptstatus = 'FINISHED' then
     /*display report in browser*/
--      web.show_document('http://steve:8888/reports/rwservlet/getjobid'||
--      substr(v_rptsvrjob,instr(v_rptsvrjob,'_',-1)+1)||'?'||'server=repsrv','_blank');
web.show_document('/reports/rwservlet/getjobid'||substr(v_rjob,instr(v_rjob,'_',-1)+1)||'?'||'server=repsrv','_blank');
else
     message('error running Report');
end if;
end;
pbranchlist is defined in the form,
repsrv is a report server i installed and explicitly started.
on clicking the button to run the above code, i get a message on the browser status bar as follows
opening http://steve:8888/reports/rwservlet/getjobid11?server=repsrv...
that's it. it stays like that forever and a progress bar showing the status of the operation gets to the halfway mark and stays there for up to 15 minutes.
I eventually halted the operation by clicking the stop button of the browser. The form then becomes totally non-responsive with the mouse indicator changing to the hour-glass shape and a small vertical bar moving rapidly back and forth at the bottom of the form window.
My only recourse then is to explicitly close the browser window.
I have already configured Reports to run in non single sign-on mode by setting SINGLESIGNON=NO in the rwservlet.properties file.
Is there anything i have not done properly?
Thanks in advance.

Steve,
can you check the Reports cache directory if the Reports file got created? I would assume yes, but better check.

You can use transaction ST22 (ABAP Dump Analysis) to view and administer
termination messages, especially those beyond their normal deletion
date.
Analisi errori
The program flow was interrupted and could not be resumed.
Program "SAPMM06B" tried to display fields on screen 0106. However, an
error occurred while this data was being converted.
Indic. per la correzione
A conversion error occurred while the program was trying to
display data on the screen.
The ABAP output field and the screen field may not have the
same format.
Some field types require more characters on the screen than
in the ABAP program. For example, a date field on a screen needs
two characters more than it would in the program. When attempting to
display the date on the screen, an error will occur that triggers the
error message.
              Screen name.............. "SAPMM06B"
              Screen number............ 0106
              Screen field............. "EBAN-MENGE"
              Error text............... "FX015: Sign lost."
Further data:
If you cannot solve the problem yourself, please send the
following documents to SAP:
1. A hard copy print describing the problem.
   To obtain this, select the "Print" function on the current screen.
2. A suitable hardcopy prinout of the system log.
   To obtain this, call the system log with Transaction SM21
   and select the "Print" function to print out the relevant
   part.
3. If the programs are your own programs or modified SAP programs,
   supply the source code.
   To do this, you can either use the "PRINT" command in the editor or
   print the programs using the report RSINCL00.
4. Details regarding the conditions under which the error occurred
   or which actions and input led to the error.
It is probably not possible to eliminate the system error
with ABAP alone.

"Error running javac.exe compiler" when using ant to compile Eclipse plugin

Hi
I encounter an error "Error running C:\jdk1.5.0_06\bin\javac.exe compiler" when building my project using ant1.7.
My project has 10 eclipse plugins, and each plugin is compiled by invoking following ant target

<target name="compilePlugin">
     
     
     <delete dir="${param.plugin.dir}/${build.dir}" quiet="true"/>
     
     <delete file="${param.plugin.dir}/${param.plugin.targetJarFile}" quiet="true"/>
     <mkdir dir="${param.plugin.dir}/${build.dir}"/>
     
     <javac      srcdir="${param.plugin.dir}/${param.plugin.src.dir}"
               destdir="${param.plugin.dir}/${build.dir}"
               failonerror="${javacFailOnError}"
               verbose="${javacVerbose}"
               debug="${javacDebugInfo}"
               deprecation="${javacDeprecation}"
          optimize="${javacOptimize}"
               source="${javacSource}"
               target="${javacTarget}"
               fork="${param.fork}" memoryInitialSize="256m" memoryMaximumSize="512m">
          <classpath refid="compile.classpath" />
     </javac>
     
     <copy todir="${param.plugin.dir}/${build.dir}" failonerror="true">
          <fileset dir="${param.plugin.dir}/${param.plugin.src.dir}" excludes="**/*.java, **/package.htm*" />
     </copy>
     <jar jarfile="${param.plugin.dir}/${param.plugin.targetJarFile}" basedir="${param.plugin.dir}/${build.dir}"/>
     <delete dir="${param.plugin.dir}/${build.dir}" quiet="true"/>
</target>
Since each of first 9 plugins contains less than 500 java source files, we always set "param.fork" to false when invoking this ant target.
For the 10th plugin, it has about 1000 source files. If we set "param.fork" to false, we will get the error "Error running javac.exe compiler". So we have to set "param.fork" to true when compiling it. This week, this plugin contains about 1250 files and we get the same error again when compiling it. I tried to increase the "memoryMaximumSize" to "768", but still couldn't get through it.
BTW, There are about 150 jar files in our classpath for compiling plugins. Do many jar files cause this problem?
Any help is highly appreciated.
Many thanks
Oceanman

I encountered a very similar error and I was able to resolve it by removing the following parameters from the javac task:
fork="${param.fork}"
memoryInitialSize="256m"
memoryMaximumSize="512m"My values were not the same as yours, before I removed them, the values were set to:
fork="true"
memoryInitialSize="256m"
memoryMaximumSize="256m" Not sure why this fixed my problem but it did. I was using Ant 1.7 and Java 1.6_07 hope this helps.
