Hi;

How can I import JAR files to my project in BlackBerry JDE.

I'm using BlackBerry JDE v4.1.0.185 and I need to import .jar files to my project.

I simply do the following steps:
1) Right-click to project and select Properties Menu Item.
2) Open the Build tab.
3) In the "Imported jar files" section, I add the appropriate jar files to my project.

After these steps my project is compiling successfully but when I try to run my application on Simulator I get the error below:

Searching installed codfiles for alias 'db4o-5.2-java1.2'
Searching uninstalled codfiles for alias 'db4o-5.2-java1.2'
Module 'db4o-5.2-java1.2' not found.Error starting <Project Name>: Module 'db4o-5.2-java1.2' not found.

I searched the forum but can not find the solution.

Regards.

I had the same problem with kxml.
The blackberry.com knowledge-center has an article about this.

This forum says, i can't post the link, so here is the text:

How To - Compile a jar file into a BlackBerry Library
Last Updated: February 17, 2005
Article Number: DB-00042


--------------------------------------------------------------------------------

Summary
This article applies to the following:

BlackBerry® Wireless Handhelds™ based on Java™
BlackBerry® Java Development Environment (JDE)


--------------------------------------------------------------------------------

Details
You can include classes from other compiled .jar files in your application. To include these files, save the .jar file in a new project, in the same workspace as your application. Make this new project a library application and make your application dependent on this library. You can then import all of its classes. To complete this procedure, perform the following steps:

To create a new project

Open the workspace that contains your application's project.
Create a new project.
To add a compiled .jar file to the project

In the navigation pane, select the project.
On the Build menu, select Project < Add File to Project.
Select the appropriate .jar file and click Open.
To make the project a library

In the navigation pane, select the project.
Right-click and click Properties. The <Project name> Class Properties window appears.
Click the Application tab.
From the Project Type drop-down list, select Library.
To compile the project

In the navigation pane, select the project.
Right-click and click Build Project.
To make the project dependent on the new library

In the navigation pane, select the project.
Right-click and click Project Dependencies. The Class depends on <Project name:> window appears.
Select the <Project name> check box.
Your application can now import the classes in this .jar file with the "import xxx.yyy.*" command.

Maybe you have to preverify the library.
But in this forum is a thread about that.

Hello;

I also saw and tried this solution. But It did not solve our problem. Can you solve the problem with Library project solution?

Thank you for your answer.

[Ryson]

Yes, it works. Did you get any error message?

[alipolatolu]

yes, I got some errors about library file that I added to library project. Firstly, I'm trying to use db4o and kSOAP libraries. I added ksoap2-j2me-core-2.1.0.jar to my library project and try to build library project only. I got some errors like below:

org.kobjects.base64.Base64: Error!: Missing stack map at label: 165

this error is about the jar library. I got same errors for db4o jar file.

My library has a main class that has a main() c'tor method. I got same error messages if there is a main class or not.

Thanks.

Thats why i said maybe yo have to preverify the package first.

The short way is:

C:\Program Files\Research In Motion\BlackBerry JDE 4.0\bin>preverify -classpath "C:\Program Files\Research In Motion\BlackBerry JDE 4.0\lib\net_rim_api.jar" "D:\RIMClient\Standard\lib\kxmlrpc_full.jar"

If you have problems:

Unpack the jar file, preverify ALL(!) the classes manually (e.g. use a batch file, it's easier) and re-jar them. Then it should work.

I suppose you're on a windows system...?

Okay, first unpack the .jar (or .zip) file (doesn't matter in which folder):

jar xf kxml2.jar
OR use a ZIP unpacker.

Notes:
1. You should check if it unpacks in the right directory structure, that means: the classes are located in subdirectories of "org\kxml2\io" and "org\xmlpull\v1".
2. When preverifying all preverified classes are saved in a subdirectory "output" by default.

Okay, now create a batch-file with the following commands:

-------------------
%J2MEWTK%\bin\preverify -classpath .;%J2MEWTK%\lib\midpapi.zip org.kxml2.io.KXmlParser

%J2MEWTK%\bin\preverify -classpath .;%J2MEWTK%\lib\midpapi.zip org.xmlpull.v1.XmlPullParser

%J2MEWTK%\bin\preverify -classpath .;%J2MEWTK%\lib\midpapi.zip org.xmlpull.v1.XmlPullParserException

%J2MEWTK%\bin\preverify -classpath .;%J2MEWTK%\lib\midpapi.zip org.xmlpull.v1.XmlPullParserFactory

cd output

%JAVA_HOME%\bin\jar -cvf ..\kxml2.jar org
-------------------

%J2MEWTK% stands for the root directory of your J2ME Wireless Toolkit (e.g. C:\J2MEWTK)
%JAVA_HOME% stands for the root of your Java2 SDK (e.g. C:\j2sdk)

P.S.: The batch file should be placed in the directory to which you unpacked the package.

Hi Ryson;

Thanks for your kind help. I tried to preverify the ksoap2 .jar file but it is not successfull. I got error while preverify operation. did you (or any one) use ksoap1 or ksoap2 with BlackBerry JDE? If so, can you please send me your ksoap library? Version is not important for now, I need to call ASP.NET Web Service functions and get response from server only :o)

I downloaded kSOAP libraries but can't work with them. Maybe, the library that I have downloaded is wrong.

Thanks and Best Regards.

[Ryson]

Which error?

[alipolatolu]

The error is below:

C:\Program Files\Research In Motion\BlackBerry JDE 4.1.0\bin>preverify -classpath "C:\Program Files\Research In Motion\BlackBerry JDE 4.1.0\lib\net_rim_api.jar" "C:\Documents and Settings\alipolat.olu\Desktop\ksoap\ksoap2\ksoap2-j2me-full-2
.1.0.jar"
Error preverifying class org.kobjects.xmlrpc.Driver
    VERIFIER ERROR org/kobjects/xmlrpc/Driver.main([Ljava/lang/String;)V:
Cannot find class java/io/FileReader

I don't know exactly what to do. If I can find a library that works for BlackBerry JDE it will be easier.

[alipolatolu]

Hi again;

I successfully ran preverify command. Now, I can run the kSOAP2 library from BlackBerry.

Thanks.

hi alipolatolu , i have the same problem problem with you. How u can run preverify command?
thanks.

[alipolatolu]

Hi;

Firstly I suggest you to use kSOAP1, It's better than kSOAP2. If you want, I can send you preverified kSOAP1 library.

I was preverified ksoap-j2me-core-2.1.0.jar, not ksoap-j2me-full-2.1.0.jar. I'm still getting same error for full kSOAP, but core library is preverifying successfully.

if you want the preverified libraries, Send me your e-mail address with private message, i will send them to you.

HTH.
Polat.

i use not only ksoap1 but also ksoap2, with both lib i can get it work , but there is always problem when importing a ksoap jar file, so i use always the source files (java files), and the two versions work good. maybe you can use ksoap1.0 jar file as alipolatolu said. i have never tried it.

good luck
