Java database component

Hi!
Is there any GUI component in Java such as the TDBGrid in the Delphi?
I mean, is there any way to manipulate data in a database through a graphic component what is NOT a JTable?
Thanks!

Not in Swing directly. Several third parties have components like this. For example, JBuilder has JDBTable. A quick google should be able to find others, some even free (sourceforge.com).
Personally, I won't use these. I have some available, but just like the GUI builder integrated into the IDE, it creates unmaintainable code. You are stuck with their interface and their methodology. Nobody will be able to modify it wilhout that IDE or incredible amoumts of time.
It takes a little while to learn all the concepts you need to code it manually, but once you do, I think it's just as fast as using their components and infinitely more flexible.

PAS/AAS JAVA instances on UNIX/Linux - database component

Hi SCN,
Firstly consider this is all UNIX/Linux based...
In the past when creating AS (or AAS now) SAP dialog instances for ABAP systems I rarely ran a SAPINST process. It was simpler to copy existing profiles and NFS mount the kernel. There is no database component relating to the instances so you could easily add/remove them
However in Java it seems there is instance data inside the database Java schema, meaning that you have to install/re-install AS/AAS instances using SAPINST/SWPM to ensure these are properly created; otherwise the instance will not connect.
Does anyone have any details on what constitutes this database component? I would like to look at it with my own eyes and see what makes it up.
Regards all, Jamie

Hi Jamie,
In case of JAVA, there we have BOX number. If you have a logical host on top of your physical host, then you can go with over scheme. Otherwise, because of BOX number, you have to go with export/import option.

It's bug?

Hi Eugeny,
If you are using the JDBC 8.0.5 driver to connect to an 8.1.4
database, you need to make sure of the following:
* within the JDeveloper IDE, open Project->Project Properties
from the menu
* in the libraries list, make sure that Oracle 8.0.5 JDBC appears
in the list of libraries before BOTH Oracle 8.1.4 JDBC AND
'Enterprise Java Beans'
If the Oracle 8.0.5 JDBC library appears after either of the
above two libraries, select it in the list, and drag it up so
that it appears first. Save your project and retry the compile.
I think this may be what is causing the errors. Please reply if
this does not fix your problem, or if I misunderstood.

Making a java browser component for Mac platform(Urgent)

I was trying to make a simple java browser component from scratch for running on Mac platform. I was using JFrame/JEditorPane. Although JEditorPane can open web pages but it can't support Javascript, flash and other interactive features of many websites. Does anyone know any way to make JEditorPane support javascript?
I also researched on JDIC java web browser, but unfortunately they don't support for Mac yet. Is there any free third party tool available which I can use?
Any quick help is appreciated. Thanks.

Add & use custom jars in "Java embedding" component

I need to generate pdf file in process.
So I included "Java embedding" component, and write my code. For clarity example:
com.itextpdf.text.Document document = new com.itextpdf.text.Document(
 com.itextpdf.text.PageSize.A4, 50, 50, 50, 50);
 try {
 com.itextpdf.text.pdf.PdfWriter pdf = com.itextpdf.text.pdf.PdfWriter
 .getInstance(document, new java.io.FileOutputStream("c:\\text.pdf"));
 document.open();
 document.add(new com.itextpdf.text.Paragraph("This is test message"));
 catch (com.itextpdf.text.DocumentException de) { System.err.println(de.getMessage()); }
 catch (Exception de) { System.err.println(de.getMessage());}
 document.close();Im using external jar file, of course I add it to classpath (right click soa project -> properties -> libraries and classpath ->add jar).
But I get folowing error (no during compilation, but during deploying):
Failed to compile bpel generated classes.

The class path setting is incorrect.
Ensure that the class path is set correctly. If this happens on the server side, verify that the custom classes or jars which this BPEL process is depending on are deployed correctly. Also verify that the run time is using the same release/version.

What the Enviroment required for java databases programs?

Hi guys
What the enviroment required for java databases programs?
If I have oracle of version 9i and java 1.4.1 platform
do I need Jdeveloper platform ?

What the enviroment required for java databases programs?What do you mean by "environment"?
f I have oracle of version 9i and java 1.4.1 platformYou just need to download Oracle's 9i JDBC driver (ojdbc14.jar) and put that in your CLASSPATH. Then write JDBC code to connect to Oracle and issue SQL commands.
do I need Jdeveloper platform ?No, JDeveloper is an IDE. Not required.
Why Java 1.4.1? We're up to Java 6 now. You're two major versions of the JDK behind.

Crystal Report Java Reporting Component Query

How to deploy a pure jave development component to server?

i have created a pure java development component.
but i cannot find a way to deploy it to server
is there any way?

You need to essencially wrap your java development component with a deployable development component.
In order to do that, you need to:
- Define a public part for your development component of type assembly.
- Create a deployable DC ( one that results in a SDA or a EAR file ).
- Reference your DC from the deployable DC. This will include the generated .jar file into the project.
The definitions of the different types can be found here:
http://help.sap.com/saphelp_nw04/helpdata/en/93/d5a73f05c4265de10000000a114084/content.htm
I would either create a library component ( results in SDA ) or a web dynpro component ( ear file ).

Re: Java Database

Hello,
I'll like some advice on the topic mentioned above. I'm a beginner of java programming and have elementry knowledge about java. I'll like to know how is it possible to input the list of data in Excel format into Java Database Connectivity and how am I able to extract out the info. that I'll need. Like say the columns/field on designation and name. How am I able to extract the data and change it like to delete or edit the info.??
Pls. explain it step-by-step your patience is really appreciated. Thanks and God Bless.

You should search Javaworld for "Excel" - they've had a few articles about using JDBC to access Excel. As far as I recall, though, you can't alter data in Excel through JDBC, only read it.
http://www.javaworld.com
There are other ways of getting at Excel data through Java but they're not very good either (unless you want to use a Java-COM bridge).

About Forms JAVA UI Component AppletSecurityException

Hi,
I have been researching how to access a custom OCX control from Web Forms 6i application, and I came up with a third-party JAVA to COM bridging solution, J-Integra from Intrinsyc.
With J-Integra I was able to build a PJC compatible JAVA component which invokes a local OCX control and was able to access the JAVA component from regular JAVA application but when I tried to invoke the component with Web Forms application I got AppletSecurityException runtime error message. I have signed the component's jar file with javakey, without success, to remove the AppletSecurityException message. How can I remove the following runtime error message from my PJC JAVA component?

I am also having the same problem.
I have signed using the PJC.x509 certificate and it is still throwing the

also ensured that identity.obj is copied to proper directory.
After following the complete instruction from PJC document,i am still having problems.Either we have incorrect document or problem and resolution section needs
to be updated.

Java Export hangs at 'Export Java Database Content' phase

Hi All -
As part of system refresh activities,we are doing Java Export from our Production system(PE1) & we will use that export to import it in our Qulaity system(QE1).So while doing Java Export,the export gets stucks/hangs at 'Export Java Database Content" phase which is the last phase in Java Export steps.We have been doing this task since many years & we did not encounter this kind of issue ever.There are no errors or at least warnings in the logs like sapinst_dev.log,jload.log,jload.java.log,sapinst.log etc.Our environment details are as below
EP -6.0
OS - AIX 5.3,64 BIT
DB - DB2 UDB
SAPINST version - 642
Java version is below
pe1adm> java -fullversion
java full version "J2RE 1.4.2 IBM AIX 5L for PowerPC (64 bit JVM) build caix64142ifx-20100918 (SR13 FP6)"
Please note with the SAPINST we are using currently, the exports of remaining systems in EP & other solutions like ECC,CR,SRM,XI,BI are successfull.We are having this issue only in PE1.Looks like some bug in code.So request the experts in this forum to please take a look at it & provide me with solution if any of you have faced the similar situation.
Thanks & regards,
Nagendra.

Thank you for your reply Subhash.The below is the last entry in jload.log.It is at EP_ATTR_HEADERS.While doing the Java export,we asked our DBA to monitor to find out any errors at DB side.He monitored and said that no deadlocks or no infinite loops are found.Also he said that he cannot create index for that too because it is trying to do select *.In our first 2 or 3 attempts it used to hang at CA_PRODUCTS meta data exported,CA_PROPERTY meta data exported.Now here.Our DBA said that EP_ATTR_HEADERS has 1.4M rows.We tried to bounce the entire system also,but no luck.We have the same issue.Peculiar thing is we dont see any errors or warnings in the logs.
23.06.11 09:54:21 com.sap.inst.jload.Jload dbExport
INFO: EP_ATTR_DEFS exported (6 rows)
23.06.11 09:54:21 com.sap.inst.jload.Jload dbExport
INFO: EP_ATTR_HEADERS meta data exported
Please let me know if you need any further info in resolving this issue.
Thanks & regards,
Nagendra.

Free Java Database?

I'm looking for a free Java database. A few recommended MySQL, but after going to their site, it looks they charge and aren't free.
The database would be used in my own commercial product that would be sold to stores. Perhaps MySQL is just free for development? Anyone know?
If anyone knows of other free Java databases that would be appreciated too.
Thanks,

You can always check out Postgres. And I'm not sure if they bundle it anymore, but there used to be a pure-Java database called Cloudscape (I think).
