calling wbeservice with axis

Hi,

I try to invoke the webservice call implemented in java(I converted the java code into dll).
I got the following error:
javax.activation.UnsupportedDataTypeException: no object DCH for MIME type text/plain
 at javax.activation.DataHandler.getInputStream(DataHandler.java:248)
 at javax.activation.DataHandlerDataSource.getInputStream(DataHandler.java:703)
 at org.apache.axis.attachments.MimeUtils.getContentLength(MimeUtils.java:73)
 at org.apache.axis.attachments.MimeUtils.getContentLength(MimeUtils.java:38)
 at org.apache.axis.attachments.AttachmentsImpl.getContentLength(AttachmentsImpl.java:438)
 at org.apache.axis.Message.getContentLength(Message.java:512)
 at org.apache.axis.transport.http.HTTPSender.writeToSocket(HTTPSender.java:371)
 at org.apache.axis.transport.http.HTTPSender.invoke(HTTPSender.java:138)
 at org.apache.axis.strategies.InvocationStrategy.visit(InvocationStrategy.java:33)
 at org.apache.axis.SimpleChain.doVisiting(SimpleChain.java:119)
 at org.apache.axis.SimpleChain.invoke(SimpleChain.java:85)
 at org.apache.axis.client.AxisClient.invoke(AxisClient.java:165)
 at org.apache.axis.client.Call.invokeEngine(Call.java:2786)
 at org.apache.axis.client.Call.invoke(Call.java:2767)
 at org.apache.axis.client.Call.invoke(Call.java:2443)
 at org.apache.axis.client.Call.invoke(Call.java:2366)
 at org.apache.axis.client.Call.invoke(Call.java:1812)

I did some research.
It looks like the axis.jar is loaded via ikvm.runtime.AssemblyClassLoader, however, the javax.activation.DataHandler( I believe it is implemented in IKVM.OpenJDK.Misc) is loaded from java.lang.ClassLoader.

Is it possible to have loaded them in the same classloader?
Or is there other way to handle this?

Thanks,
Jun

Hi,

The class loader of javax.activation.DataHandler is null (aka the bootstrap class loader). In IKVM.NET you cannot add stuff to the boot class path (except by recompiling the boot class library), but I seriously doubt that's necessary. Most code in the boot class library uses either the system or the thread context class loader.

Jeroen

Hi Jeroen,

Yes, you are right. The class loader of javax.activation.DataHandler is
null and it is bootstrap class loader.
Just wondering how can I add/recompile the axis.jar in the boot class
library. (I know it is awful).
Otherwise, not sure if anyone else used the axis via IKVM since I don't
really want to rewrite those web service code in c#.

Thanks,
Jun

Just another thought, is there any old version of IKVM which does not
include activation in the boot library?
I can build activation.jar and axis.jar in the same assembly.

Hi Jeroen,

I thought that the cause of the problem is that those two jar files
(activation.jar and axis.jar) are NOT in the same classloader.
Currently, the axis is loaded in system class loader (I guess the
AssemblyClassLoader is the default one).

Thanks,
Jun

No. javax.activation uses the system class loader. The attached example shows that and it also shows how you can change the system class loader.

Hi Jeroen,

Thank you so much for your kindly help and I understand your point now.
And I do have my own system classloader.
Anyway, I tried the code in a new project and I got the exactly error
message.
Just wondering if it is related with the version(0.40.0.1) I have.
Will try to download a new version...

Best regards and have a good weekend,
Jun

Re: calling wbeservice with axis

by Jeroen Frijters :: Rate this Message:

Reply to Author | View Threaded | Show Only this Message

The sample I posted didn't solve the problem. It was only a hint on how to solve the problem. It shows that javax.activation uses the system class loader and that you need to set the system class loader to a class loader that knows how to load META-INF/mailcap (i.e. delegate to the axis assembly class loader).

I've attached something that should work. BTW, you must make sure that the java.system.class.loader system property is set before any other Java code executes, otherwise you run the risk of getting the default system class loader.

Jeroen

Hi Jeroen,

Great!
It is working after I managed to invoke a static method before the log4j
logger.

Really appreciated!

Best Regards,
Jun
