Oc4j_client.zip incomplete?

Hi,
I checked out oc4j_client.zip (ver.10.1.2), then unpacked it on disk. There's some folders tree: dms, j2ee, jdbc, lib, opmn. Where some folders have their subfolders. I verified some jars declared in classpath in commandline when I started my J2EE client application inside JDeveloper IDE. I noticed some differences, e.g. in oc4j_client in folder j2ee/home/lib weren't jaxp.jar, jcert.jar, jndi.jar, jnet.jar, jsse.jar and oc4j.jar. In folder lib wasn't xmlcomp.jar
In fact oc4j_client has oc4jclient.jar but I afraid it isn't an equivalent for these absent jars. Simply test made me sure, because I couldn't start my application based on oc4j_client entry, but I could start the same inside JDeveloper IDE.
What's going wrong?
Thanks for some help
Krzysztof

See this thread for a complete list of all the jars you will need in your clients classpath:
Re: javax.naming.NoInitialContextException:
I worked this out by trial and error because at the time the link to oj4j_client.zip was broken. It has worked perfectly for me ever since.

Oc4j as service on windows server.

Hi experts
I am trying to making oc4j as automatic service on windows server 2008 ,
I research the forum and found some steps , i followed that but , it not working for me kindly help
step i followed..
I only installed developer 10g on my local machine and downloaded oc4j Standalone Version 10.1.2.0.2.
1. Download the oc4j_client.zip for 10.1.2 from www.otn.oracle.com.
2. Unzip oc4j_client.zip file into d:\oc4jclient. Download the ojdl.jar file and place it in the c:\oc4jclient folder.
after that I unzipped oc4j Standalone file into c:\oc4jclient.
at the end I followed metalink document How to Run OC4J 10.1.3 As a Windows Service? [ID 742424.1]
1. Download JDK 1.5 and install it
2. Download JavaService-2.0.10 from:
http://forge.objectweb.org/project/showfiles.php?group_id=137
3. From command line enter the following command:
javaservice -install “Oracle BI EE OC4J” “C:\Program Files (x86)\Java\jdk1.5.0_15\jre\bin\server\jvm.dll”

Unexplainable error while invoking EJB

I'm have an EJB session Bean version 2.0 deployed on OC4J (Oracle Application Server Containers for J2EE 10g (9.0.4.0.0) created and deployed by Jdeveloper 9.0.5.16.15.
When I invoke the bean remotely using Remote client, I include the Jars ejb.jar and (oc4jClient.jar, or oc4j.jar) WHICH ARE IN THE JDEVELOPER OR OC4J DIRECTORY, the client works perfectly.
But when I copy the above JAR files and paste them in a different directory and I attempt to run the client i get the following error:
java.lang.NoClassDefFoundError: javax/transaction/SystemException
     at com.evermind.server.rmi.RMIServer.addNode(RMIServer.java:856)

     at raya.ps.demo.HelloWorldClient.main(HelloWorldClient.java:17)
I am guessing that the oc4jClient.jar or the oc4j.jar are depedany on other JAR files which are found in the same directory which can be found under the Jdeveloper/j2ee/home and oc4j/j2ee/home that's why they the client works when present with other JARS, i just guessing because I couldnt understand what's going on. If other JAR file needs to be included along with OC4J clients, what are these JARs and where am I going wrong ?
Thank you

Ok, I got it working now, I found there's an OC4J_Client.zip not just oc4jClient.jar which has to be included in the classpath.

Some libraries for client J2EE

Hi,
What're appropriate libraries for running some J2EE client? When I test some client inside JDeveloper IDE, then several libraries're declared in classpath, but what's necessary for launching this client and connecting to any J2EE application deployed on OC4J?
Regards
Krzysztof Malinowski

Thanks for your tips!
I made some test with jar file from oc4j_client.zip Therfore there's only one important jar: oc4j_client.jar
Take a look at this command line:
java -classpath D:\JDeveloper\jdev\mywork\MyWorkplace\Project\classes;D:\JDeveloper\OC4JClient\j2ee\home\oc4jclient.jar mysf.SFacadeClient
This's a minimal info needed in classpath declaration (actually I use also addressing my directory where mysf package exists, the first part in classpath)
The important thing is in my client class (SFacadeClient) I put appropriate info for InitialContext, factory class, url, user and password to OC4J. In case of lack those paramiters, the classpath declaration should address ...\oc4j-config\.client file with default InitialContext parameters.

Error(4): java.util.zip.ZipException: incomplete literal/length tree

hi
our team working on a ADF project , each one was developing some pages on his local machine , after i sucessfully integrating all 3 projects into one single project manually , i've tested it , and it seems it runs ok , i imported this project on CVS , and then i checked it out later, when i try to rebuild the checked out project i go that error while trying to compile jsp pages.
ANY ONE KNOW , what's the problem

Hi,
I guess it's a waste to reply to an article after such a long time, but I recently have been assigned the task to get my team up to the mark using CVS. Now I am using cvsnt 2.5.03.2382, initially i did have problems which i did narrow down to the libraries which were imported into CVS.
But now when i only use CVS on the project level (while continuing to import libraries) no errors occur.
The error you have mentioned did come to me also, but I just wanted to inform you that CVS works on the project level.
Also if you don't mind
Could you provide me with details such as the version of CVS you were using and the technology or templates associated with the application?
Also, that whether have you later tried using libraries with CVS?
any information would mean a great help top me.

Zoheb

Powershell Script Send-zip not working when running in cmd

I found there is powershell send-zip script available in technet. I tested it and found that it works when the script is running under powershell env, but when it is calling in cmd env, I can see the zip file, but there is nothing in it. If
I add the "-noexit" switch it runs normally. Anyone have ideas what might be happening?
The orig codes is as following:
function global:SEND-ZIP ($zipfilename, $filename) {
# The $zipHeader variable contains all the data that needs to sit on the top of the
# Binary file for a standard .ZIP file
$zipHeader=[char]80 + [char]75 + [char]5 + [char]6 + [char]0 + [char]0 + [char]0 + [char]0 + [char]0 + [char]0 + [char]0 + [char]0 + [char]0 + [char]0 + [char]0 + [char]0 + [char]0 + [char]0 + [char]0 + [char]0 + [char]0 + [char]0
# Check to see if the Zip file exists, if not create a blank one
If ( (TEST-PATH $zipfilename) -eq $FALSE ) { Add-Content $zipfilename -value $zipHeader }
# Create an instance to Windows Explorer's Shell comObject
$ExplorerShell=NEW-OBJECT -comobject 'Shell.Application'
# Send whatever file / Folder is specified in $filename to the Zipped folder $zipfilename
$SendToZip=$ExplorerShell.Namespace($zipfilename.tostring()).CopyHere($filename.ToString())
SEND-ZIP C:\abc\a.ZIP C:\a\a.bak

I've had the same problem with similar code found on another web site.
The reason the zip file ends up being empty is that the temporary $ExplorerShell object you created is deleted when the send-zip function returns,
and any incomplete copy operation that may still be ongoing at that time is aborted. (The copy operation is asynchronous, and continues after the CopyHere() function returns.)
To work around this, you need to add a delay loop before you return, waiting for the copied object to appear in the zip.
(Note that adding a fixed delay, like I've seen on other web sites, does not work: Small files appear almost immediately, whereas large file or worse still large subdirectory trees can take a long time to appear.)
Try changing the end of your routine to something like...
# Create an instance to Windows Explorer's Shell comObject
$ExplorerShell=NEW-OBJECT -comobject 'Shell.Application'
# Open the zip file object
$zipFile = $ExplorerShell.Namespace($zipfilename.tostring())
# Count how many objects were in the zip file initially
$count = $zipFile.Items().Count
# Send whatever file / Folder is specified in $filename to the Zipped folder $zipfilename
$SendToZip=$zipFile.CopyHere($filename.ToString())
# Wait until the file / folder appears in the zip file
$count += 1 # We expect one more object to be there eventually
while ($zipFile.Items().Count -lt $count) {
Write-Debug "$filename not in the zip file yet. Sleeping 100ms"
Start-Sleep -milliseconds 100
# Return deletes the $zipFile object, and aborts incomplete copy operations.

Incomplete Data on report (report does not show all records from the table)

Hello,
I have problem with CR XI, I'm running the same report on the same data with simple select all records from the table (no sorting, no grouping, no filters)
Sometimes report shows me all records sometimes not. Mostly not all records on the report. When report incomplete sometimes it shows different number of records.
I'm using CR XI runtime on Windows Server 2003
Any help appreciated
Thanks!

Sorry Alexander. I missed the last line where you clearly say it is runtime.
A few more questions:
- Which CR SDK are you using? The Report Designer Component or the CR assemblies for .NET?
- What is the exact version of CR you are using (from help | about)
- What CR Service Pack are you on?
And a troubleshooting suggestion:
Since this works on some machines, it will be a good idea to compare all the runtime (both CR and non CR) being loaded on a working and non working machines.

Why does captivate 5 scorm 2004 change the pass/fail status when using complete/incomplete

SUMMARY: I am trying to use SCORM 2004 reporting but I am finding out ADOBE does not diffentiate between COMPLETE/INCOMPLETED and PASSED/FAILED variables in the SCORM 2004.
RESULT: I can not accurately get the passing/failing status from the course.
QUESTION: Is their anything I can do or does ADOBE have a patch they have release which will accurately report the passed/failed STATUS as well as the completed/incompleted status.
OTHER RESEARCH: I even attempted to post these "proofs" on scorm.com and they have something called "SATISFACTION TRACKED" to accomodate content creation systems (CAPTIVATE 5) which does not follow the standards of SCORM 2004.
BACKGROUND: the report status "Incomplete/Complete" and "Pass/Fail" under the publishing options for SCORM 2004 essentially mean the same thing when the CAPTIVATE COURSE sends setvar commands to the SCORM API... In other words the SCORM API receives the same exact commands when publishing in both modes. "THIS IS WRONG"
why is the wrong? IF REPORTING; incomplete/complete ; the CAPTIVATE 5 COURSE SHOULD NOT "change" the STATUS OF PASS/FAIL when attempting to report COMPLETE/INCOMLETE with 100% slide views.
DEMO #3> SHOWS THE PROBLEM
About DEMO #1 and DEMO #2> these are other reporting options I attempted with other problems arrising..so these images are just for supporting my original problem which is shown in DEMO #3...
DEMO 1 (REPORT STATUS has no affect on reporting):SETTINGS:
PASS: (PROBLEM)
Anything above Passing Score is not recorded to LMS (once passing is reached...no more bookmarks are recorded)
FAIL: (CORRECT)
Failure gets sent to the database on the last screen with "completed"
DEMO 2 (Report status [Complete/Incomplete Pass/Fail] has no impact on commands sent to scorm api):
SETTINGS:
PASS: (CORRECT)
Very Last page gets sent to the Database
FAIL: (PROBLEM)
NOTHING GETS SENT TO DATABASE (stuck in final score screen forever)...because it says "INCOMPLETE"
DEMO 3:
Report status [Complete/Incomplete Pass/Fail] has no impact on commands sent to scorm api
SETTINGS:
PASS: (CORRECT)
Very Last page gets sent to the Database with a 90% passing with "completed"
FAIL: (PROBLEM)
LAST SLIDE SENDS "completed" but GETS SENT AS A PASSING SCORE??? even when it is a failure
(IN OTHER WORDS ADOBE CHANGES THE PASS/FAIL STATUS based on slide views...
this is WRONG ....REALLY WRONG becuase I am trying to report
"COMPLETE/INCOMPLETE" for 100% slide views
PASS/FAIL OPTIONS:
OPTION I CAN PURSUE?
SO WHAT CAN I DO? YES, I CAN TELL THE LMS...to COMPARE THE SCORE RECEIVED DURING A "COMPLETE" status...and then change the grade in the LMS based on the SCORE IN THE LMS...BUT THAT WOULD MEAN THE LMS COULD REPORT ONE GRADE and the COURSE COULD REPORT A DIFFERENT GRADE....and that would not be good.
ALL OF OUR COURSES SHOW THE STUDENT THE FINAL SCORE WITHIN EACH COURSE..
QUESTION TO ADOBE?
SO ADOBE when are you going to differentiate these two reporting options so that the PASS/FAIL OPTIONS ARE ACCURATELY REPORTED WHEN USING COMPLETE/INCOMPLETE?
MORE INFORMATION
HERE IS THE SCORM.COM "Satisfaction" adjustment (very last line) to accomodate inconsistent reporting in CAPTIVATE 5.

These two field were designed to help differentiate the difference between a passing or failing score and when the course is actually completed. WITH CAPTIVATE 5 they do not differentiate the two. COMPLETE means PASS and INCOMPLETE means fail..
I was trying to use "completion_status" as a way to determine when all slides were shown. So that I can send the final score (PASS/FAIL) the LMS after all slides were viewed and this was the absoluted score the student recieved.

CPTX WHY DOES CAPTIVATE CHANGE PASSING STATUS

CAPTIVATE SCORM SUCCESS_STATUS COMPLETE STATUS MEANS THE SAME THING
CAPTIVATE SCORM SUCCESS_STATUS COMPLETE STATUS SHOULD BE INDEPENDENT

Hi,
Here's something I found in a similar situation... hope this helps!
After publishing your CP5 project as a SCORM 2004 zip file, unzip the file so you can get into the separate files. Open the imsmanifest.xml file with a text editor; I like using Notepad++. Search for the line starting with <imsss:minNormalizedMeasure>. The complete line will probably look like <imss:minNormalizedMeasure></imss:minNormalizedMeasure>, this is the line that is supposed to contain your passing score (at least for our LMS). So, if your passing score is supposed to be 80%, edit this line to be: <imsss:minNormalizedMeasure>0.80</imsss:minNormalizedMeasure> and save the file. Then select all the files and re-zip them, I use 7-zip for that.
I found one other weird thing that doesn't happen 100% of the time, so test it. In the example above, try to get a score of exactly 80% (or whatever passing grade you are using) and see if you get the correct status reported. I found I sometimes have to re-edit that line in the manifest file to be 0.79 so it correctly includes an exact 80% score. No idea why and you have to watch the number of questions in your quiz to make sure that works for you mathematically.
If this works or not, I'd recommend posting your results so others can get some ideas. Good Luck!!

Problem with ZIP file download

I try to download a ZIP file from some URL. Everything goes fine, but I never get the entire content of the file (1.79 MB size).
Here a code snipet:
byte[] data = new byte[conn.getContentLength()];
Object obj = conn.getContent();
java.io.BufferedInputStream bis = (java.io.BufferedInputStream) obj;
bis.read(data);
bis.close();
File f = new File(sPath.toLowerCase());
FileOutputStream fos = new FileOutputStream(f);
fos.write(data);
fos.flush();
fos.close();
Any ideas? Thanks in advance.
Frank

I think the real problem is that you don't check the return value from read (it's probably less than data.length indicating an incomplete read). Isn't there a readFully somewhere?

Downloading zip files - problem

I have a program which is supposed to allow download of a zip file to the users PC and then write a record to a database showing that the user has downloaded the file.
When I try and read the file I have downloaded I get an error message which says the zip file is incomplete.
Here is the code which downloads the file
docname = material.getFilelocation().substring(slashpos+1,material.getFilelocation().length());
// reformat file name to work with getRealPath
material.setFilelocation(dirname+"\\" +docname);
//read data from file
sc= getServletContext();
String fileaddress = sc.getRealPath(material.getFilelocation());
File resfile = new File(fileaddress);
FileInputStream fileIn = new FileInputStream (resfile);
BufferedInputStream in = new BufferedInputStream(new DataInputStream(fileIn));
// Set up output to client
res.setContentType("application/zip");
res.addHeader("Content-Disposition", "inline;filename="+docname);
OutputStream ds=res.getOutputStream();
byte b[]=new byte[1024];
int len =0;
while ((len=in.read(b))>0) {
ds.write(b,0,len);
in.close();
getfilelocation has format -directory/filename.zip
Does anyone know why the file is incomplete?
Thanks
Suzan

while ((len=in.read(b))>0) {There you are. You stop reading the input when you
reach the first zero byte. The documentation for this
method says
"If no byte is available because the end of the
stream has been reached, the value -1 is returned."I doubt that's the problem. The API does say that -1 is returned on EOF, but if it isn't going to return -1, then it will read at least 1 byte, stuff that into the array, and return the number of bytes read - which won't be zero unless the size of the array passed to it is zero (which it isn't).

Incomplete XML files using xmlparserv2 to trans

When processing XSL using a large XML file (288K), and version
xmlparserv2.jar from xdk_java_9_0_2_0_0C.zip I get an incomplete
destination XML file. It appeared that more than 99% was
translated but it wasn't 100%. I replaced that version with the
one from xdk_java_9_0_1_1_0A.zip and it works; that is, I get
the complete (100%) document.
Anybody?
Thanks,
Dave

I have had problems with that particular jar as well. I run on
Solaris but I had to download the current Solaris Beta version
to get my classes to compile and then I have to run my
application with the current production version.
The problem I experience is a corrupt class in the
xmlparserv2.jar (oracle.xml.parser.v2.XMLDocument). This class
gives a Null Pointer Exception when I run a javap on it from the
production jar.
You are not alone in trying to find the version that works for
your particular environment! Good Luck.......

Integrationevent.wsdl incomplete ?

Hi.
I have to access to an Integration Queue created.
In other posts, I 've read that I have to download the integrationevent.wsdl and generate a proxy, for example with jdeveloper.
I 'm using jdeveloper 10.1.3.5.
I 've downloaded others .wsdl from "web services administrator" and I 've generated succesfully with jdeveloper proxies for them, get and set data in crm object (I've generated proxies for account, activities,contacts and products).
But When I unzip integrationevent.zip and I check integrationevent.wsdl I see the sentences:
<service name="IntegrationEventWS">
-<port binding="tns:IntegrationEventWS" name ="Default">
*<soap:address location="http://CHANGE_ME"/>*
</port>
</service>
In others wsdl, for example product.wsdl I always see
<soap:address location="https://secure-ausomxgba.crmondemand.com/Services/Integration">
I try to change http://CHANGE_ME for "https://secure-ausomxgba.crmondemand.com/Services/Integration"
but When I load wsdl in jdeveloper to generate proxy, Jdeveloper finnish with validation failed:
The name .proxy.Default_Binding_IntegrationEventWSLmpl is not a valid Java class name.
So, What address do I have to write in http://CHANGE_ME???
Why is integrationevent.wsdl incomplete?, or I have to do some change in the set up before???.
Any comments could be useful.
Thanks
Best Regards
Marcosob.

Hi Marcosb,
Apologies, I thought I had posted a reply to this message some time ago. Due to the fact that the Integration Events WSDL file is distributed within a .zip file, it is necessary to set the address location value manually. For other WSDL files this substituted dynamically. You should use the same address location value that is set in other WSDL files you have downloaded.
Please let me know if you are still having problems with Integration Events.
Thanks,
Sean

Wrong metadata retrieved when using Oracle8.1.7 + classes12.zip

Hi,
I am using Oracle8.1.7+classes12.zip+jdk1.2.2.
I am always retrieving the wrong metadata for the tables. The same piece of code works fine when using Oracle8.1.5+classes111b.zip+jdk1.2.2.
The code is as follows :
try {
db = Database.getDatabase();
con = db.getConnection();
ps = con.prepareStatement("SELECT * FROM " + tablename);
meta = (ps.executeQuery()).getMetaData();
} catch(SQLException e) {
Debug.log("ServerMetaCache::requestMeta " + e);
System.err.println("ServerMetaCache::requestMeta " + e);
return null;
The following is a list of the column name retrived from the metadata :
TABLE_CAT
TABLE_SCHEM
TABLE_NAME
COLUMN_NAME
KEY_SEQ
pk_name
Anyone encountered this before?
null

The code I posted above was incomplete.
The complete code is as shown below:
db = Database.getDatabase();
con = db.getConnection();
ps = con.prepareStatement("SELECT * FROM " + tablename);
meta = (ps.executeQuery()).getMetaData();
try {
int count = meta.getColumnCount();
columns = new ColumnDefinition[count];
System.out.println("tname = " + tname);
System.out.println("column count = " + count);
for (int i = 0; i < count; i++) { // arrays starts from 0 while columns start from 1
String colName = meta.getColumnName(i+1); // get the database name for this column
System.out.println("colName = " + colName);
catch(SQLException e) {
System.err.println(e.toString());
The result is :
tname = Product
column count = 6
colName = TABLE_CAT
colName = TABLE_SCHEM
colName = TABLE_NAME
colName = COLUMN_NAME
colName = KEY_SEQ
colName = PK_NAME
null
