Workspace problem : project has no Java Nature.

Hi,
I'm having this problem since I tried to deploy and run an ESS application for testing. here are the details of problem.
An internal error has occured. See error log for more details.
Plugin name: Metamodel Core
Plugin ID: com.sap.ide.metamodel.core
Class: com.sap.ide.metamodel.core.plugin.MetamodelManager
Method: getJavaProjectClassPaths
Message: project has no Java Nature. projectName = GDI_XSS11dev_Dessgbaddrsap.com
Exception: org.eclipse.core.internal.resources.ResourceException: Missing project nature class for org.eclipse.jdt.core.javanature.
Same problem is being reported for every DC in NWDS Web Dynpro perspective and perspective is not loading correctly. I changed the workspace and perspective came back fine - with no DCs of course.
I'm using NWDS 7.0.20 and j2re1.4.2_14.
Could you help me solve this problem?
Regards,
Vishwas.

Hello Vishwas,
No re-installation needed actually. Since the corrupted files are basically the meta files of the workspaces at .dtc (best to back that up though). If you're using NWDI, the track should appear there alongside LocalDevelopment and 0. If its a critical project, I would recommend perhaps raising an OSS note on how to fix this NWDS bug.
I can think of ways to perhaps 'refresh' the local file DCs -- but I'm not totally sure if its safe or it could have consistency issues with the activities logged on your DTR.
Goodluck!
Regards,
Jan

XMLBeans build aborted for project ...project was missing Java nature.

I always get this project level error in an OSB Project in Workshop whenever I add XMLSchema resources to the project and try to create XQuery Transformation resources. The project is then unusable and may not be deployed to OSB. I have tried adding the Apache XMLBeans and Java 6.0 facets, but that does not eliminate the problem. I can delete the project, create a new project, and copy all of the files from the old project to the new project but, as soon as I attempt to edit the XQuery Transformation, the error returns. The OSB Project in Workshop is, essentially, unusable if you want to add XQuery resources to your project. An OSB project without XQuery resources is just a Webservice, so using OSB isn't necessary. The only thing we have found that works it to edit the project in the OSB console.
The full error string in the Problems View is:
XMLBeans build aborted for project XXX because project was missing Java nature.
Any workarounds? Solutions? Configuration changes?

This is a strange error, because OSB projects do not use facets/natures/builders provided by Eclipse for any resources within the project. OSB has its own mechanism for validation on OSB Projects, so it's surprising to see any error messages from an XMLBeans builder relating to the Java nature.
Can you look at the OSB Project's properties and see if there are any facets/natures/builders/validators on the project?
The only builders should be:
- Faceted Project Validation Builder
- Validation
The only facets should be:
- AquaLogic Core Facet
- Oracle Service Bus
The following Validators should be disabled:
- WSDL Validator
- XML Schema Validator
Thanks,
Nadeem

FYI... This issue was a result of installing WLI 10gR3 into the same HOME as OSB/ODSI 10gR3. I am able to publish the projects iwith the error into a local WLS but can not export into a jar file for import into a seperate WLS. I would like to keep WLI and simply "fix" the java nature issue if possible.
Thanks in advance

I have a project that crashed on me when I was about to finish it. When I try to reopen Final Cut Pro it wouldn't open until I took the project out of the Final Cut Project folder. Can somebody tell me if this is a problem that has a solution? I cannot go back to the project at all.

If you are using 10.0.3 or above Apple added a backups folder that for a little extra protection in cases like this. If you quite FCPX go to your Final Cut Pro Projects folder. Find the folder that has the project in question. If it has a backups folder there should be a file with a date stamp and .fcpproject extention, that is your back-up. Just move the back-up from that folder one folder up to the place where you deleted CurrentVersion.fcpproject from. When I have had to do this I haven't renamed the backup but some people to recomend that you rename it to CurrentVersion.fcpproject and it seems to work both ways. Ofcourse it wont work if there is already a CurrenVersion file there you will need to delete that one first.
If you don't have the backups folder or there is nothing in it I am not sure if there is anything that can be done.

I have problem in this unzip java codes

hi all,I have problem in this unzip java codes,I think either the pathway that i put C:.......is wrong or the codes are wrong because when i run it, the zipped folder is not unzipped. So anyone has another set of example or know how to correct it? Thanks!Please post the solution here!
This is the set of codes that i have:
import java.io.*;
import java.util.*;
import java.util.zip.*;
public class Unzip {
public static final void copyInputStream(InputStream in, OutputStream out)
throws IOException
byte[] buffer = new byte[1024];
int len;
while((len = in.read(buffer)) >= 0)
out.write(buffer, 0, len);
in.close();
out.close();
public static final void main(String[] args) {
Enumeration entries;
ZipFile zipFile;
if(args.length != 1) {
System.err.println("Usage: Unzip zipfile");
return;
try {
zipFile = new ZipFile("C:\\Temp\\FolderZiper.zip");
entries = zipFile.entries();
while(entries.hasMoreElements()) {
ZipEntry entry = (ZipEntry)entries.nextElement();
if(entry.isDirectory()) {
// Assume directories are stored parents first then children.
System.err.println("Extracting directory: " + entry.getName());
// This is not robust, just for demonstration purposes.
(new File(entry.getName())).mkdir();
continue;
System.err.println("Extracting file: " + entry.getName());
copyInputStream(zipFile.getInputStream(entry),
new BufferedOutputStream(new FileOutputStream(entry.getName())));
zipFile.close();
} catch (IOException ioe) {
System.err.println("Unhandled exception:");
ioe.printStackTrace();
return;
}

What does the program output when it's executed? Can you copy the screen and post it here? More info can help solve the problem.
What exactly is the program supposed to do?
Add some more println() to show the program flow and what the values of key variables are. For example what is in entries after the entries() method is executed?
Some prep work on your part would make it easier for us to help.

OC4J not running after creating workspace and projects.

Created one workspace and added six projects. Added PostGes jar to library manager. Before doing this, the OC4J would run a test application successfully. After creating the workspace and project, I created another simple workspace with two JSP, on linked to the other. When trying to run this project get the following:

Remove the posgres jar from the library manager and still not able to run simple two page applications.
All the projects in the other workspace compile fine. The prolblem is that now I am not able to use the internal OC4J. I remove the workspace with the five projects, and the JARs and the two page app will not run.
The OC4J is running when launched from the IDE, ti just can find the pages.
New install of JDEV and the two page app will run fine. Add two user two user libraries and the app will not run.
Thank you,
Ben Carter

Do you have a database connection to postgress defined in JDeveloper?
JDev might be picking this up and trying to add a datasource for it to the embedded OC4J - so try removing it, or alternatively add the postgress JDBC driver jar files to the libraries node under tools->embedded OC4J preferences.

Problems 'hosting out' of java

Hi,
JDeveloper version 9.0.3.1035
Windows NT
I am having problems 'hosting out' of java. The dos command shell is opened but little else happens.
I am trying to run a batch file called test.bat that has contents: -
notepad.exe
My code is : -
public static void host(String[] cmd, boolean wait)
throws IOException, InterruptedException
//Run jobs asynchronously
Runtime rt = Runtime.getRuntime();
for (int i=0;i<cmd.length;i++)
logger.debug("Command being run is : " + cmd);
Process process = rt.exec(cmd);
if (wait)
logger.debug("Waiting for process to finish.");
process.waitFor();
logger.debug("Process exit value : " + Integer.toString(process.exitValue()));
The debug output is :-
Command being run is : "C:\test.bat"
Waiting for process to finish.
Process exit value : -1073741510

Hi Guys
After attempts was able to install with license page being displayed in English. H/ever since then I have had a bit of a problem trying to run Secunia Software Inspector which requires the use of Java, The problems which I am experiencing are as follows:
When the program starts I receive the following
quote
Java(TM) Plug-in Fail Error
Several Java Machines Running in the same process caused an error
Your Systm does not appear to have sun java installed. Sun Java is required for the Secunia Software Inspector to work. You should consider downloading the latest version of Sun Java from http://www.java.com/ before continuing.
unquote
Eventually the program closes resulting the following message appearing on desktop
quote
ieplore.exe application error, the instruction at 0x2e746e65 referenced at 0x2e746e65. The memory could not be read.
unquote
The bottom line is that I have Mozilla Firefox browser installed and when I run the program using this browser there is absolutely no problem. Runs like a dream. Because of this factor I am wondering why there is so much problem running it using IE
Any help appreciated.

Not able to see DC project in Webdynpro java perspective in 7.0

HI,
i want to modify an iview in NWDI-DC project.
i have imported my SC into NWDI. then created project in existing DC. but cannot see that project in webdynpro java perspective.

Hi,
are you sure it was a WD DC ? Can you see the project available in the perspective Resource ?
Are you using by any chance 700 NWDS on windows 7 ?
Was the project creation really succesful? Check the ".log" file available in the ".metadata" folder of your nwds workspace (or check the Error Log view you can switch on using window -- show view -- other...).
Thanks and Regards,
Ervin

Somehow, I do not have java anymore. i tried to update, and all of a sudden, it says it has no java anymore... can someone help?

Hi
i tried updating java, because a game i used to play no longer supports my version. after the update mac has provided, java had not updated in my browser, thus i downloaded it from a site. after doing this, firefox does not even find the applet. can anyone help me PLEASE!?

For Mac OS X 10.5, Apple's Java Update 10 removed support for JavaPlugin2, preventing Firefox versions 4.0 and above and other non-Apple browsers from detecting that Java is installed. Mozilla fixed the problem in Firefox 5.0.1 and above so this should no longer be a probem if you applied the latest Firefox update.

Receiving "project has expired" message in LMS

I'm getting messages from users of our LMS system that they are encountering the message "project has expired" when opening one of our trainings. I understand that this is because my trial expired (Captivate 7) awhile ago, but I have since licensed an older version of Captivate (5.5). I've been attempting to open the project that was created in the Captivate 7 version so that I can republish, but am encountering the following message:
Is there a way for me to reopen this project so that I can republish without having to build this all from scratch? I've read similar posts, but have been unable to find the answer to my problem. Any help would be greatly appreciated!

This topic may help explain what is going on:

Problem with win2000sp3 and Java web start

I have JRE and Java web start (1.2.0_01, build b01) which come downloading file j2re-1_4_1_01-windows-i586-i.exe from sun.
I have win2000pro running on my PC.
I had updated win2000 to service pack 2 and everything was fine.
Now i decided to update to service pack 3 (in the process I also updated other components) from Microsoft and:
1) Java applets seem to be running fine within i.e.
2) If i try to run an application from java web start my PC freezes and I have to restart it.
3) Staroffice 6.0, which runs on Java, seems to be fine.
I reinstalled both sp3 and jre etc, with no result.
Is this a known problem?
Thanks to all.
Maurizio

I suspect that you have hit a known problem with Swing on Java 1.4.1 with buggy video drivers. Do you have an ATI card? They are the worst offenders. ATI released new drivers for its Radeon line today. They fix the problem.

Photoshop CS5.1 will not even open. Says it has encountered a problem and has to close.

I have just today downloaded a free trial of Adobe CS5.1, but when I try to open it, it brings up the loading screen, and then when it says "Starting-up plug-ins, Scripting Support" an error message comes up saying "Adobe Photoshop CS5.1 has encountered a problem and needs to close.
This also happens when I try to use Photoshop Elements 8. It will not let me on to the Organiser.
As well as this, I had a problem with bridge. Whenever I tried to download images onto my computer, it said "Adobe photo downloaded has encountered a fatal error. Error code: c0000005 (I cannot remember what the address was though). I uninstalled bridge and then tried to download CS5.1 so I could get bridge again, but it has only made things worse!
What should I do?
Thanks
Oscar

Ok I did that and it said
"Faulting application photoshop.exe, version 12.1.0.0, faulting module scriptingsupport.8li, version 10.0.0.0, fault address 0x000d1a2e."
This would make sense as when I try to start photosohop CS5.1 and the strtup screen appears, when it says "Starting-up plugins, Scripting Support" that it was the message "Adobe Photoshop CS5.1 has encountered a problem and has to close" comes up.

Workspace problem : project has no Java Nature.
