Problem creating jar using JDeveloper

I'm creating jar using JDeveloper..I need to keep two dll files in the jar. But if I create the jar in JDeveloper, it can't include the dll files. If the jar is created from command prompt, it can include the dll files. Can anyone tell me how can I include these dlls in my jar?

Putting DLLs in your classes directory is dangerous (eg. Run->Clean Project.jpr will remove it). I use a different way to achieve that:
When you double click on the deployment profile you'll see a dialog window containing a list of items. The one of interest is the one called File Groups. Select this item, click on the New button and add a new file group just for your DLLs.

Executable JAR using JDeveloper

Hi,
I created a very small Desktop Application using JDeveloper.
What I want to do is to create an executable JAR file. I mean, is there any option in this tool like the one in Eclipse. Once executable JAR is created, I must be able to run it just by double clicking the JAR file.
So, can some1 please help me with the steps ?
JDeveloper : 11.1.1.6.0

For executable jar you will need to add:
Main-Class: your_package.YourClassto META-INF/MANIFEST.MF file inside jar.
I don't think that JDeveloper support custom manifest files so you can modify this content after jar creation(for example, with some zip/rar/7z tool)
Also, if your app require some additional jars, then you will need to add this line to manifest:
Class-Path: additional.jarDario

Problem creating Jar in Eclipse

I have a problem in exporting my eclipse java project to a jar file. It does not include the external jars used in the buildpath in the MF file. How to add external jars used in the project propoerties' buildpath in the MF file while exporting a Java Project to a jar? Thanks in advance.

hi,
there is no possibility in eclipse to export the external files from class path.
but you can add the source files of your .jar to your project without using the class path.
that should be the solution of your issue :)

How to create reports using jDeveloper

what procedure to follow in order to creating
reports drawn from mysql or Oracle 8.5.0 database.

I have created 'reports' using BC4J and the JSP Web Application wizard (I use the RowsetBrowser bean).
On the BC4J side, I use read only View Objects based on SQL queries (not based on Entity Objects).
On the JSP side, I create a HTML form where the user can enter their query criteria, pass that criteria as parameters to the ViewObject query, then use a RowSetBrowser bean to display the results.
You can also write your own custom beans to format the output of the report as you like.

Hi,
Please check the WM config for the Warehouse / Movement type(Tx. OMLX) . There we have option to give as immediate confirmation. This may be the reason for TO getting confirmed when created.
U can this by creating a transfer order for the same movement type manually in TX. LT03. After you save if the To is confirmed then its a config setup @ Warehouse / Movement type.

Problem creating dataset using db2 stored procedure in Eclipse BIRT

Hi,
I am using DB2 9.7 Express Edition in Eclipse BIRT(version 2.5.1) for generating reports. I have used Type4 driver for jdbc connection.
For that, I have established jdbc connection using db2jcc.jar and db2jcc_license_cu.jar files.
I have successfully created data source, say DB2BIRT having following requisites-
Driver Class - com.ibm.db2.jcc.DB2Driver ( v3.50)
Driver URL - jdbc:db2://localhost:50000/database_name
User name - user_name
Password - Password
I have written some stored procedures and trying to use resultsets from those stored procedures into my report..
The stored procedures having involvement of only single resultset are working absolutely fine for new dataset using above DB2BIRT.
But, I am unable to create new dataset using stored procedures those having involvement of multiple resultsets.
I am getting following error as -
org.eclipse.birt.data.engine.odaconsumer.PreparedStatement$SequentialResultSetHandler getMoreResults
SEVERE: Cannot get more result sets from the statement.
Cannot get the result set.
SQL error #1: [jcc][10120][10943][3.50.152] Invalid operation: statement is closed. ERRORCODE=-4470, SQLSTATE=null

Moreover, I tried to resolve above issue by changing Driver Class from com.ibm.db2.jcc.DB2Driver ( v3.50) to com.ibm.db2.jcc.uw.DB2StoredProcDriver ( v3.50)
So again while *"Test Connection"* for new Data source using this new driver class for stored procedure, there is an error reflection as -
org.eclipse.birt.report.data.oda.jdbc.JDBCException: The selected driver cannot parse the given url.

Can anybody address my this issue for successful implementation of stored procedure(with involvement of multiple resultsets) for creating Data set in Eclipse BIRT ?
I will be really thankful.
Thanks in advance,
Manasi

Well, in my stored procedure I have used 2 to3 cursors(as per my business logic) and all cursors except one are holding result sets. That exceptional cursor is intended for holding as well as returning result set after call to the procedure. And its perfectly running on db2 and returning the desired output. The problem is with Eclipse. The same procedure is not working in Eclipse BIRT.

Problems creating jar in netbeans - Failed to load main-class

Hi,
I was wondering if someone could help with a problem I'm having creating a jar. I have a project in netbeans 6.5 and used Netbeans' GUI Builder (matisse) to create some of the UI elements in the project. I've tried many times to do "Clean and Build" to build my project. It builds successfully, but the jar that gets created gives the following error:
"Failed to load Main-Class manifest attribute from C:\... filepath here...."
I checked the manifest file, and that contains:
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.7.1
Created-By: 11.0-b16 (Sun Microsystems Inc.)
I tried adding Main-Class: gui.MainGUI (which would be the class that contains my main function) to this file and tried running it again, but it then said "Invalid or corrupt Jarfile" when I try running it. MainGUI does exist in the Jar. I also tried with just Main-Class: MainGUI, same error.
Does anyone know what I'm doing wrong? In NetBeans, if you go to the project properties, Main Class is specified as "gui.MainGUI" also, so that isn't the issue. Additionally, I have Swing Layout Extensions and Swing Application Framework included in the added libraries (required for the GUI builder, I think).
Thanks for any help.

Try creating a new Java project and be sure to choose project type Java Application.
Copy source code to the newly created project and try again.

thanks

Well if you are just starting with JDeveloper - why are you starting with an old version?
You should start with 10.1.3 it has hundreds of new features over 10.1.2.
I created a struts action in 10.1.3 copied your code into it and compiled without any problems.

Problem creating CalculationView using Eclipse on MacOSX

Hi guys,
   I'm trying to follow the steps of tutorial Using HANA Modeler in SAP HANA Cloud Platform, but it's giving a error when creating the Join of SO_CV view when running on MacOS Leopard. When I link the tables SNWD_BPA and SNWD_SO the link is erased and when I try using the Join wizard I cannot click on finish or Add a column as output.
But when I do the same steps on Windows it's works without problem. I've done the procedure several times in both systems, and only get error on MacOS.
Anyone else having this issue ?
Regards,
Cleber Santz

Hi Vladimir,
   I already have a updated Eclipse (Kepler) install:
    UI5: 1.20.7
    HANA Tools: 1.0.7400
    HANA Cloud Tools: 1.27.0
    NEO J2EE 6 SDK: 2.34.6.1
   When the problem occurs, it cause a graphic issues as well on View Diagram. See image attached.

Problem Creating Portles Using JAVABEANS

I have an application that uses JSP and JavaBeans that works perfectly outside of a portlet. When implementing it as a portlet it is unable to find the JavaBeans.
I have stored the JavaBeans in the default /WEB-INF/classes directory. The JSP files are in their own directory.
Request URI:/jnetjsp/adminusersearch/AdminUserSearch.jsp
Exception:
oracle.jsp.parse.JspParseException: Line # 28, Error: Unable to find class for bean: UserResults defined by tag with class: adminusersearch.UserSearchResults
9iAS 1.0.2.2.0

You need to make sure that your JavaBean classes are on the classpath. Not sure why you mention the WEB-INF directory, it doesn't exist under JServ.
As far as I remember you need to edit the wrapper.classpath entry in the jserv.properties file. For example, if you have your beans in a the mybeans.jar file, you'd need to create an entry like this:
wrapper.classpath=D:\jpdk\lib\mybeans.jarand copy mybeans.jar to the D:\jpdk\lib folder.
Hope this helps.

Problems creating .jar

I want to create a jar-file to speed up my applet. I don't know how...
If I got it right I have to write the "jar cvf MyApplet.jar MyApplet.class images" where I have the jar.exe. That should be in:
C:\j2sdk140\bin\
But the files I want to jar is in another directory because I connect to a database:
C:\mysql\mm.mysql-2.0.14\
What shall I do?

Problem exporting JAR using Eclipse with JNIlib

Hi all,
I have a java application that is using an external JAR. The external JAR is coupling with a JNIlib.
When I 'export' my application to a runnable JAR in Eclipse, the external JAR is extracted and included in my runnable JAR. However, when I execute the runnable JAR, some functions of the application is not working due to missing library. After I put JNIlib into my Java/Extension, the runnable JAR then works fine.
I want to distribute the JAR to other people, but I can't ask them all to put JNIlib in their Java/Extension.
Does anyone have an idea? I am a novice to Java, it took me awhile to figure out how to create a runnable JAR.
Thank you very much.
Eagle.

first , it says unable to access jar file .
upon deeper inspection i found that background processes is created behind thus the jar file been activated but the UI doesnt show up? any more idea of where my codes gone wrong? which seems perfect for me
anyway thanks but i still .. it says unable to access jar file
