Need help getting opatch and java working on 10g

I am trying to configure opatch on a Solaris 2.9 Unix server with Oracle 10g
We don't have java installed. How can I get the required java installed and opatch and OUI (Oracle Universal Installer) working?
Thanks
Ben P

u can download java from Sun's site and install it in any location. Use -jdk or -jre option and specify the path to java, while invoking opatch, then it works fine.

Could not get schema Object:java.sql.SQLSyntaxErrorException ora-904

All of a sudden I get
Could not get schema Object:java.sql.SQLSyntaxErrorException: ORA-00904: "SYS"."O"."NAME": ongeldige ID
when doing anything in the tables tree in the connections pane
The only thing I set recently is pga_aggregate_target
Environment
Oracle 11.2.0.1
OS Windows Vista Ultimate sp2
Sql developer 2.1.1.64.39 with its own JDK
As the download links on OTN are broken I can not upgrade, and I'd rather not work in command line sqlplus.
Help!!!

My copy of sqldeveloper isn't located in that directory. Would that matter?
In the mean time I have disabled filtering the tables node. Opening the tables node doesn't result in exceptions anymore.
Now, when I click on any table in that node I get 4 identical ora-904 error messages for sys.o.name for any table.
Apparently it is querying either the all_objects view and it thinks it is querying sys.obj$.
I didn't yet enable sql_trace for the session, I'm more or less giving up on sqldeveloper. I can not use the space bar in any datagrid, sqldeveloper has always been extreemly unresponsive when navigating the schema browser (as opposed to Toad), etc, etc. Too bad I bought Sue Harpers book, but I think I will be de-installing sqldeveloper soon.

While opening SXMB_IFR i am getting a error Java.lang.noclassFounderror

U have installed SAP XI in my laptop while opening
SXMB_IFR i am getting a error Java.lang.noclassFounderror
so i not able to go further please help me
thanking you
sridhar

Hi,
There are number of ways to do that :
1. Try this url
http://<host-name or IP address of XI server>:<java Port number)>/rep/start/index.jsp
If this is successful that means your J2EE server and services are fucntioning fine. The problem could then be on the ABAP stack.
2. Can you start visual admin tool and check that all the services are running. You might have to manually start those which have not automatically started. Check the connectivity with all system & server (inc n/w) & Register the hostserver entry in your sys32/ host file
e.g 10.2.4.56 <server name>
3. Have you download java sdk 1.4 on you laptop?
http://java.sun.com/j2se/1.4.2/download.html
also have a look at this sap note: 801868
(make sure not to install the 1.5 version of JWS. XI does not work properly with the 1.5 version)
4. Lastly, u might have some problem with ur JRE installation. In that case i would sugesst you to re-install JRE/ Java WebStart.
This blog may help you to analyze the errors-

XI Mail Adapter: sending emails with attachment with help of java mapping

Hi ,
On trying out the scenerio mentioned in the blog, using the java mapping provided
"XI Mail Adapter: An approach for sending emails with attachment with help of Java mapping
The scenerio works just fine.
But the payload as the content of the attachment is not getting generated in proper XML format.
I suppose it's because of the replace special characters code part..
Can anyone help me state the modification required in the code.
Thanks!
Regards,
Faria Mithani

It might be a codepage issue. Is your original payload UTF-8?

Getting Error in java mapping: Parsing empty source. Root element expected!

Hi Experts,
   I am using java mapping for schema validation of input message. I have followed all the standard procedures and implemented the java class in the interface mapping.
My interface mapping is like this:
OrderData --->Java Class ---SchemaValidate
                     Mesg Map ---OrderData_to_BAP --->BAPI Msg
So first I want to validate the schema of the input message. If the input message is invalid then XI should throw an exception. Then I use the actual message mapping to map the input order data to the BAPI input parameters.
In the java code I am using xerces parser.
The java code works fine when I run it as a standalone application.
The interface mapping also works fine if I don't include the java mapping. Ofcourse schema validation does not happen.
But when I test the interface mapping by including the java mapping then I am getting the error:
Call method execute of the application Java mapping SchemaValidate
Java mapping SchemaValidate completed. (execute() of SchemaValidate
com.sap.aii.utilxi.misc.api.BaseRuntimeException: Parsing an empty source. Root element expected!
What am I doing wrong? Why it is not getting the root element?
My Java code is as follows:
import com.sap.aii.mapping.api.StreamTransformation;

Hi Stefan,
   I did the code changes to return output stream and the java code works perfectly in standalone mode in my PC.
   But when I use the same in the Java mapping with XI then It throws an error "Getting Error in java mapping: Parsing empty source. Root element expected!".
My XI J2EE server has JDK1.4.3.11.
Is there any limitation of using SAX parser in XI? If Yes, then which parser should be used for schema validation in XI?
I have included the XSD file for schema validation along with class files in the .jar file. This jar file is then imported in XI repository. Is the XI engine not able to read the XSD file?
Do I have to handle reading XSD file differently? Any suggession how?
Is this parser error due to some security access?
Kindly help me! I have been struggling with this problem since 2 weeks. I will be greatfull to you if you can help me.
Thanks
Gopal

Any idea when we will get support for Java 7.5 in Safari?

I'm in school for a degree in software engineering and Java is a big part of it. As a regular Mac user who uses Safari as his main browser, it's disappointing that adoption of the latest Java versions in Safari seem to be lacking. Is there any way to get Safari to look at the latest versions of Java instead of being stuck on Java 1.6?
Thanks in advance for any help! :-)

Apple has kept up to date (more recently) with the latest releases of Java 6 (1.6.0_33), which is the current public release of Java. You can install the development Java 7 runtime from Oracle (currently on build 5), but this will not support many features and functions of the final release. All future updates to Java will be issued and maintained by Oracle as it's done on other platforms. Apple will not be offering an in-house Java runtime after Java SE 6. You can get the latest Java updates here: http://www.oracle.com/technetwork/java/javase/downloads/index.html

Getting started in Java Comm API

Hi This is all new to me. So I would really appreciate if anyone can help me figure this out..I am trying to read from the serial port using a VS4000 Image Scanner(Symbol). I want to scan a driver's license bar code. I believe PDF417 is the type of barcode to read driver's license. However, Im just curious if there is any code out there that actually parses the information out of the license. I need to get the lastname, firstname,dob,gender,address,drivers #, etc.. Does any one have any idea where I could get more information in how to scan a driver's license. I need more guidance in how to really do this. Although, I went to the introduction to Java Communications and found a example code "SimpleRead.java". However, I get some errors....
can anyone help..I have a nullpointer ..not sure how to fix it...
I get this error :

Thanks a bunch!! :)
Jess...

I actually got my scanner to work. I got my SimpleRead.java to work as an application. I set up this as an applet. Now my problem is that I the inputread reading from the serial port is not reading correct data always. It sometimes does scan correct data at times and other times it will not. So, I am not sure what is wrong. Does anyone have any clue why this could happen?

Rename exported file in ODI with help of Java

Hi.
We have to implement new scenarios into execution repository. I marked scenarios and I exported them with help of procedure:
OdiExportScen "-SCEN_NAME=#scen_name" "-SCEN_VERSION=-1" "-FILE_NAME=#DEP_EXPORT_DIRECTORY\SCEN_#SCEN_NAME 001.xml" "-FORCE_OVERWRITE=YES" "-RECURSIVE_EXPORT=YES" "-XML_VERSION=1.0" "-XML_CHARSET=windows-1251" "-JAVA_CHARSET=cp1251"
But I have to put space between variable #SCEN_NAME and another part of file name. After export I want to rename file with help of Java script, but I get an error when I try to read list of files.
import java.io.*;
public class RenameFiles
     public static void main(String[] args)
          String dirPath = new String ("D:\\ODI");
          File dir = new File(dirPath);
          String dirList[] = dir.list(); /* I get error there*/
          for(int i=0; i<dirList.length; i++)
               File oldFileName = new File(dirPath+"\\"+dirList);
               File newFileName = new File(dirPath+"\\"+dirList[i].replaceAll(" ","_"));
               oldFileName.renameTo(newFileName);
Error in ODI Operator looks like:

I fixed it.
All I need - put slashes at end of directory name. Also I removed implementation of class.
import java.io.*;
String dirPath = new String ("D:\\ODI");
File dir = new File(dirPath+"\\");                // I put \\ at the end of directory name
String[] dirList = dir.list();
for(int i=0; i<dirList.length; i++)
     File oldFileName = new File(dirPath+"\\"+dirList);
     File newFileName = new File(dirPath+"\\"+dirList[i].replaceAll(" ","_"));
     oldFileName.renameTo(newFileName);

Help with Java Printing-Custom paper sizes

Hi,
I'm trying to print documents with custom paper sizes out of java.
I can print fine when I don't try to set the MediaSize to a custom size or when I use already named constants like: "MediaSizeName.JIS_B4"
The error message I get is this:
java.lang.ClassCastException
     at javax.print.attribute.AttributeSetUtilities.verifyAttributeValue(Unknown Source)
     at javax.print.attribute.HashAttributeSet.add(Unknown Source)
     at hello.Printy.printDocument(Printy.java:103)
     at hello.Printy.main(Printy.java:135)
The offending line(103) looks like this:
pras.add(new MediaSize(1,10,MediaSize.INCH ));The function that its from looks like this:
public void printDocument()
try
          System.out.println("input file name is");
     System.out.println(inputFileName);
PrintRequestAttributeSet pras = new HashPrintRequestAttributeSet();
DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE;
PrintService printService[] = PrintServiceLookup.lookupPrintServices(flavor, pras);
PrintService defaultService = PrintServiceLookup.lookupDefaultPrintService();
PrintService printPrintService = null;
// didn't work pras.add(new MediaSize(1,10,MediaSize.INCH) );
PrintService service = ServiceUI.printDialog(null, 200, 200,printService, defaultService, flavor, pras);
if (service != null)
     System.out.println("There is a service aunty-may!!");
DocPrintJob job = service.createPrintJob();
FileInputStream fis = new FileInputStream(getInputFileName());
DocAttributeSet das = new HashDocAttributeSet();
//pras.add(new MediaSize((float)3.25, (float)4.75, Size2DSyntax.INCH ) );
// - works
//pras.add(MediaSizeName.JIS_B4);
pras.add(new MediaSize(1,10,MediaSize.INCH ));
//pras.add(new MediaSize(1,10,MediaSize.INCH) );
     System.out.println("Doc has been set to custom size");
Doc doc = new SimpleDoc(fis, flavor, null);
job.print(doc, pras);
     System.out.println("any doc for you?");
catch (Exception e)
e.printStackTrace();
}Any help with this would be greatly appreciated. I'm new to java but I've programmed a bunch in c++.

Hmm ... no real help, but I found this note in the API:
MediaSize is not yet used to specify media. Its current role is as a mapping for named
media (see MediaSizeName). Clients can use the mapping method
MediaSize.getMediaSizeForName(MediaSizeName) to find the physical dimensions of
the MediaSizeName instances enumerated in this API. This is useful for clients which
need this information to format & paginate printing.

Migrating from JavaHelp to Oracle Help for Java

Currently we have a product in which we have implemented Sun Microsystem's JavaHelp as the Help delivery system. However, after evaluating Oracle Help for Java we would like to migrate from Javahelp to OHJ.
My question is, how difficult would this migration be from the Development side? I have been reviewing the Oracle Help for Java Developer's Guide and comparing it against the JavaHelp documentation but I haven't been able to get a clear idea of how different the implementation is.
Thanks,
Theresa

Hello Theresa,
Thanks for considering Oracle Help.
There isn't much you have to do with your source content and control files. With the exception of the full text search index, the Oracle Help control file formats (helpset, index, map, etc.) extend the JavaHelp formats. So you can use the JavaHelp control files as is, or you can extend them with the Oracle Help extensions. For a quick overview of differences, see the following page in the Oracle Help Guide:
1. Go to http://otn.oracle.com/ohguide/help/.
2. Click "Oracle Help File Formats."
3. Click "Comparision to Javahelp File Formats."
To create an Oracle Help full text search index, run through the Helpset Authoring Wizard and remove the existing JavaHelp search view and have the wizard generate an Oracle Help Search index
on the following wizard page. For the Helpset Authoring Wizard doc:
1. Go to http://otn.oracle.com/ohguide/help/.
2. Click "Authoring Oracle Help Systems."
3. Click "Using the HelpSet Authoring Wizard."
Alternatively, change the helpset file by hand. For the doc:
1. Go to http://otn.oracle.com/ohguide/help/.
2. Click "Oracle Help File Formats."
3. Click "Helpset File."
Then run the indexer. For doc:
1. Go to http://otn.oracle.com/ohguide/help/.
2. Click "Authoring Oracle Help Systems."
3. Click "Using the Full-text Search Indexer."
On the development side, the APIs are different, but they are also very
simple. You create a Help object, add HelpSets, and associate topic-ids
with java UI components using the CSHManager as described in the
Oracle Help Guide:
1. Go to http://otn.oracle.com/ohguide/help/.
2. Click "Oracle Help for Java Developer's Guide."

We have basically the same issue when we try to create the interpreter using the embedded method..
I was able to use the interpreter embedded in a java client as long as the weblogic jars were located in a weblogic install if I tried to use them from a maven repository no luck at all...
All of this worked easily in 9.2 now in 10.3 it seems more error prone and less documented.
I have seen close to a 100 posts on issues related to this so is there a document which outlines specifics....
We / I have used weblogic now for almost 10 years and moving from 8.1 to 9.2 was painful and we expected the move from 9.2 to 10.3 not to be soo bad but its proving to be as painful if not more painful than moving to 9.2. We seem to spend a good bit of our time working around issues in the next new release that were not in the previous one..
Any help would be appreciated I think we will open a support case but even that is more painful...
Any help would be greatly appreciated..
PS: We confirmed that all jars in the startweblogic classpath were in the startup. The server we have the embedded wlst instance is a managed server and we are using the component in a war... Are there any restrictions which we are unaware of.
Error we get is
