Java Question ... has private access in ..

[wl]

Hi,

I'm creating a library and I was succesful in generating the library through SLC.

This is the main (simplified) Java code:

@BA.ShortName("FakeSMTP")
@BA.Version(1.0f)
public class FakeSMTP
{
    public FakeSMTP() {
    }
}

Already when I declare variable of this type

    Dim fk As FakeSMTP

I get:

FakeSMTP() has private access in FakeSMTP

Try removing the constructor. It is not necessary here as you do nothing in it. Java provides a default empty constructor.

Thanks, but that did not help.

No other suggestions possible without seeing the source.

Hi,

This is driving me nuts. I simplified it to:

a file called FakeSMTPServer.java in the \src subfolder of the folder to which SLC refers.

package net.wapps;
import anywheresoftware.b4a.BA;


@BA.ShortName("FakeSMTPServer")
public class FakeSMTPServer
{
    private BA ba;
    private String eventName;

    public FakeSMTPServer() {

    }

    public FakeSMTPServer Initialize(final BA ba, final String eventName) {
        this.ba = ba;
        this.eventName = eventName;
        return this;
    }
}

The library is compiled to a FakeSMTP.jar and FakeSMTP.xml in a folder to which my Additional Lubraries of my B4J environment refers.

When I write following code and compile I now get this error message:

Two things.

1)
Initialize should be a void function - it doesn't need to return anything but may be doing no harm depending upon whether B4A B4J can accept the different signature.

2)

a file called FakeSMTPServer.java in the \src subfolder of the folder to which SLC refers.

It should be in \src\net\wrapps

Hi Andrew,

Moved it to \src\net\wapps and transformed the Intitialize to a void ... same result ...

Strange! If you post your actual library source file, just so we are definitely using the same code, I'll try it tomorrow afternoon as I'm busy in the morning. Post your compiled jar and xml for comparison as well.

EDIT: By actual I mean that cut down version that doesn't seem to work.

Hi Andrew,

I think it has something to do with the naming of the internal files of the library. I did some renaming and I did manage to resolve the problem.

However: another problem pops up:
- SLC compiled the project (it has some external jars in the lib subfolder)
- now when I run the B4J proejct using my library I got a ClassNotFound error: it seems that the JAR file the SLC created does not include the classes I need from the external libs ?

does not include the classes I need from the external libs ?

SLC does not add any jar your are using....

You need to add a reference to the jar/aar using #additionaljar or with depends_on inside your wrapper.

What internal files? You didn't mention that All you indicated was that a simple source file compiled but gave a runtime error.

Hi Andrew,

No the reason was that I simplified the setup to just one file and I see got the error. But then this was probably caused by the file structure.
Before I had a reference to other java files and I did try the file structure but it did not work.

Long story short: not sure what *exactly* was the reason but now I have another issue I won't bother you about

Thanks
