"Data too long for column" in mysql

[byersa]

I am muddling thru this and thought I would throw it out to see if anyone
has some experience with it.

I am using mysql 5.0.37
I have set the character set type in entityengine.xml to "utf8", dropped the
db and ran run-install

First I got a "max_allowed_packet" error when trying to upload an image
file. I fixed by changing my.cnf. to allow up to 2M.

Now I get a "Data too long for column" on a blob field. The file size is
700KB.

Right before the error in console.log, there are these warnings:

2008-03-20 14:32:49,741 (http-0.0.0.0-8443-Processor2) [
ObjectType.java:949:INFO ] No type conversion available for
java.nio.HeapByteBuffer to java.nio.ByteBuffer, returning original object.
2008-03-20 14:32:49,743 (http-0.0.0.0-8443-Processor2) [
GenericEntity.java:408:WARN ] In entity field [ImageDataResource.imageData]
set the value passed in [java.nio.HeapByteBuffer] is not compatible with the
Java type of the field [java.sql.Blob]


Thanks for any insight.
I am going to take a nap now. Please have your answers ready for when I wake
up.

Thanks,
-Al

Hello Al,

I think you can make some changes to the type of the data of the image file
which you are uploding.
The type of the image data which is saved in ImageDataResource is "blob". So
i think you need to convert the data to ByteBuffter then you can save data
in the ImageDataResource Entity, also where you are uploading it in the
service the type of attribute can be "java.nio.ByteBuffer".

For this i think you should also read the file back from ImageDataResource
to check whether the data uploaded.

Thanks Pranay,

This was helpful, but I am chasing my tail trying to find out where
java.nio.HeapByteBuffer is loaded. That is what is returned in
ServiceEventHandler at line 217. I find that HeapBuffer.allocate returns an
object of HeapByteBuffer type, but can't find that in Java APIs for ver.
1.42, 1.5 or 6.0. Is that what the current version of Tomcat is using?

Any help here would be appreciated.

Thanks again,

Hello Al,

Yes I also agree to that we are not having the class HeapByteBuffer in
java.nio package in Java APIs. I have also gone through ServiceEventHandler
and found that we are just wrapping up the byte array into a ByteBuffer.
When i applied a search for HeapByteBuffer in *.* got one result which is in
SqlJdbcUtil.java.
Also tried to find out the documentation for this class and found a relevant
link for this, may be this link can be of help.
http://dmi.ensica.fr/doc/Java/j2sdk-1_4_2-doc/docs/j2h/java.nio.index.html.

Pranay,

I found that HeapByteBuffer is a private subclass of ByteBuffer, which is
why you don't see it in the apis. I don't think it is the problem. When I
get around to it, I am going to upgrade my version of MySQL and try
Postgres, as well.

Hello byersa,

This is a rather late comment for this post.  Did you by any chance find a solution to this problem?

Thanks,
