Who is the author of java.lang.Object

Here�s what the source of it says in JavaDocs

Compilation unit indirectly references the missing type java.lang.Object

Hi All,
I am getting the below mentioned error

How to add the missing java.lang.object

hi guies:
when i build the ui dc, an error occurs. it reminds me that the path is incomplete.the compliation indirectly references the missing type java.lang.object.
if you once confronted the same problem as me and resolved it ,pls told me.
thanks a million!

The JDK is not in path of the DC build.
Hence you are getting this error.
Check that correct JDK is pointed in preferences.

HELP!! Deploying with DC, missing type java.lang.Object

Hi Folks,
I have a WebDynpro project created with a DC. I have been deploying the project directly from the application node, but I just built the associated DC for the first time, and now I get errors in my source code that I have the missing type java.lang.Object.
I have tried the repair-->project structure and classpath option already. Looks like some basic links are broken.
This is hopefully simple, but I have no Idea what I need to do.
Thanks

Hi there,
If it's because of broken links, did you try closing the project and opening it again?
Kind regards,

_call.setOperationName(new javax.xml.namespace.QName("Urn:ApiService", "getAllUsers"));
setRequestHeaders(_call);
setAttachments(_call);
try { java.lang.Object _resp = _call.invoke(new java.lang.Object[] {});

Where in that code do you claim you are doing that? Post a SSCCE .

Support of Query newQuery(java.lang.Object compiled)

The implementation of the Query newQuery(java.lang.Object compiled)
method doesn't copy the Class of the candidate instances but it should
ad the documentation says :
"All of the settings of the other Query are copied to this Query, except
for the candidate Collection or Extent."
Thanks.

You can't query on a blob column.

Sure, it's nice to satisfy a bit of curiosity, but since the information is quite deliberately not present in the publicly available source code, it's pretty safe to assume it's not available anywhere else. You seem to have gone from "I'd like to know" to "I demand someone tells me", and I'm unsure why. Or maybe I'm just reading you wrong, in which case, I apologise. But I don't think you're going to get an answer, and it really doesn't matter

1)what is the reason for this problem
2)in weblogic document they told to edit server.policy file in webligic\lib folder
a)what the modification is needed in this file..?

Hi jerry
i already got that problem solved by removing jaas.jar file
from class path.
i don'nt how it is working with out in classpath...?
Jerry <[email protected]> wrote:
Hi Nivas,
I think that the problem you are seeing has something to do with the
placement of jaas.jar in your classpath
On WebLogic server, put jaas.jar in the classpath after weblogic.jar.
I would bet that you have it placed before weblogic.jar right now.
I don't think the exception that you're seeing right now has anything
to do with your weblogic.policy file right now, so I think it is
safe to not worry about it right now.
Hope this helps,

Error: invalid file 'java/lang/Object.class' (wrong version: 48, expected 4

hi all
ive installed jdk1.4.1 from jdk1.3 .
When i try to compile a java file i get this error.
Error: invalid file 'java/lang/Object.class' (wrong version: 48, expected 45)
anyone has any idea abt this.
im stuck :( pls help.
thanks

Did you uninstall 1.3 completely? Completely in the sense both jdk and jre.
You may get this error if you use javac of one version and the rt.jar of another version.

NoClassDefFound java/lang/Object error

Hi all,
I just tried to install JRE 1.4.1 on Win98 and encountered this error when I typed in java -version:
error occurred during initialization of VM
java/lang/NoClassDefFoundError: java/lang/Object
After I installed I added SET CLASSPATH = and the path to my rt.jar and tools.jar to my autoexec.bat, but that didn't seem to work.
Sorry about posting this here if it isn't appropriate, I tried a forum search but kept getting Server Error.

Look at this thread:
http://forum.java.sun.com/thread.jsp?forum=54&thread=106425
Think it is reply 3 or 4, where you have to rename the the java.exe file somewhere in your system path

Sort(java.util.LinkedList java.lang.Object ) doesn't work

Why doesn't this work?
LinkedList<Object> sysPropsKeys = new LinkedList<Object>(System.getProperties().keySet());
Collections.sort(sysPropsKeys);
cannot fnd symbol
symbol : method sort(java.util.LinkedList<java.lang.Object>)
location: class java.util.Collections

I will admit to not having Java1.5 installed on my machine. Haven't yet had the chance to play with generics, but the above DOES work in 1.4, and SHOULD work in 1.5
Maybe I'm naive but, System.getProperties() returns a Properties object right?
According to the API: http://java.sun.com/j2se/1.5.0/docs/api/java/util/Properties.html: Each key and its corresponding value in the property list is a string.
All the keys SHOULD be strings.
AFAIK string are comparable, and shouldn't throw class cast exceptions
Thus the keys returned from getProperties SHOULD be comparable, and compatible for comparision.
Ok, I can see your point in that some hackers abuse the Properties class by putting non string keys/values into the Properties Map. In that case the code would become more like your above. I'd probably still go with a TreeMap though, rather than a sorted list of keys. Most time you want the keys, you want the values as well. So if the intention is to print out a sorted list of system properties, and their values, keeping it in a map is best.
Just my 2 cents,

Javah error java.lang.Object not found

Hi guys-
I'm trying to run a javah command to generate a .h file... I'm using windows2000 & jdk1.1.8... when I run the command from DOS prompt I keep getting the same eror as java.lang.Object not found: aborting.. I've checked all the classpath and it seems ok ... I have CLASSPATH=..;c:\jdk1.1.8\lib\classes.zip
Can anybody help me with this???
Thanx

Maybe try ; right click my computer ,click the advanced tab and select enviroment variables,click on classpath and then edit,check if it's correct.I had the sam problem and that seemed to fix it. :)
