Bug with binary functionallity

[u4ibm]

We moved from using SGWT 2.3 22-12-10 nightly build to the latest 2.4 nightly build.

From that changed we get "Closed connection" on any binary function we use.
(when re-building with 2.3 it works)

We use ojdbc5, windows xp, and Oracle9 DB.

Is it a known bug?

[Isomorphic]

Not a known bug, and samples that use binary are working. Trying putting together a test case.

[u4ibm]

sorry the problem is not with binaries but with clobs.

[u4ibm]

it reminds us of this fix: http://forums.smartclient.com/showthread.php?t=12275&page=3

and to be more clear, the problem is both with BLOBs and CLOBs.
(we can`t download BLOBs and view CLOBs)
and it is working when we recomiple with 2.3

[u4ibm]

we tried uploading to a server with JNDI (using 2.4) and it made the CLOBs functionality work, but BLOBs are still not working (on server the all blobs seem to be null..)

thanks!

Please post all the required information (the text you need to delete in order to post).

[u4ibm]

we're using smartgwtee

our developing environment is completely detached from the internet, that is why we usually don't add logs/code etc.
I've copied some of the stack traces manually this time.

let's seperate the two problems:

1. The Clob problem: only on hosted mode
when we try to fetch from a DS which has clobs in it we receive the following exception on the server side:
java.io.IOException - ConnectionClosed
.
.
oracle.jdbc.driver.OracleClobReader.read(line 136)
.
.
com.isomorfic.util.IOUtil.copyCharacterStreams(183)
com.isomorfic.util.IOUtil.copyCharacterStreams(127)

when we deploy it on our weblogic server it works fine, it also works with 2.3
again we already encountered this problem: http://forums.smartclient.com/showthread.php?t=12275&page=3

2. The Blob problem: happens on both hosted and deployment
All the Blobs seems to be null at client side, and when I try to upload a binary file I get a not very informative Exception on the client side

RPCManager:Error performing:'....._update' error:FAILURE
.
.
sun.reflect.NativeConstructorAccessorImpl.newInstance0()

we're using ojdbc5.jar if it makes any difference.

This also works on smartgwtee 2.3

I hope It's clearer now...

[u4ibm]

anyone?

we can`t move to 2.4 without it :\

[u4ibm]

isomorphic?
if you need more details than that please let us know.

[Isomorphic]

Is this with a "sql" DataSource or some other type? And what are the types of the CLOB and BLOB fields in your.ds.xml file?

[u4ibm]

1. yes an 'SQL' datasource
2. CLOB- text of a length of 10000
BLOB - binary

[u4ibm]

anything new?


thanks!!

[Isomorphic]

Yes, this was a bug which has now been fixed.

[u4ibm]

we tried with the latest nightly build.

it fixed the CLOB issue,
but BINARY fields are still seem as null in the client.

[u4ibm]

OK, we figured out what was wrong.

Record.getAttribute() for binary fields started returning null for some reason even if the binary field wasn't null.
We can check the *_filesize or *_filename attributes to see if the field is null.
