Empty content from any version

[travmik]

Hi, all
I have very big problem. Can somebody help me?

I create node:


Node rootNode = session.getRootNode();
Node documentNode = rootNode.addNode("test.txt", "nt:file");
Node resNode = contentNode.addNode("jcr:content", "nt:resource");
resNode.setProperty("jcr:mimeType", "text/plain");
resNode.setProperty("jcr:encoding", "UTF8");
resNode.setProperty("jcr:lastModified", System.currentTimeMillis());
resNode.setProperty("jcr:data", new ByteArrayInputStream(doc1.getInStream()));
documentNode.addMixin("mix:versionable");
session.save();
documentNode.checkin();


Then i update node like this:


Node documentNode = session.getRootNode().getNode("test.txt");
documentNode.checkout();
Node resNode = contentNode.getNode("jcr:content");
resNode.setProperty("jcr:data", new ByteArrayInputStream(doc2.getInStream()));
session.save();
documentNode.checkin();


And then i try to get data from content node:


Node node = session.getRootNode().getNode("test.txt");
VersionHistory hist = node.getVersionHistory();
Version vers = hist.getVersion(versionName);
Node frozenNode= vers.getNode("jcr:frozenNode");
Node versionNode = frozenNode.getNode("jcr:content");
InputStream  data = versionNode.getProperty("jcr:data").getStream();

And all properties are setting up, but property with key "jcr:data" is empty for all versions from versionhistory. Why?? What do i do wrong?
Many thanks,
Stas

The JCR API access looks good. I think the problem lies in the usage
of the input stream. For example, ByteArrayInputStream does not take
an InputStream as parameter in any of its constructors (it should be a
byte[] parameter, but doc2.getInStream() sounds like it returns an
InputStream):

resNode.setProperty("jcr:data", new ByteArrayInputStream(doc2.getInStream()));

Alex

Thank you for you prompt reply. But method getInStream() in my transfer object returns byte[]. In this section it's alright.
I run my project using jcr-jca on jboss 4.2. Maybe it helps.
I am confusion.((

I have this problem for now. Though this code works fine:


Node rootNode = session.getRootNode();
Node documentNode = rootNode.getNode("test.txt");
Node contentNode = documentNode.getNode("jcr:content");
InputStream  data = contentNode.getProperty("jcr:data").getStream();


"data" - not empty. And when i try do this with version i get empty data from content node.
I am not understanding what i do wrong.(

What is "versionName" from the code in your first mail? Could you
iterate over all versions in the history, print them out and check if
they contain data? You can do it with VersionHistory.getAllVersions().

Yes i did this. Data in all versions from VersionHistory is empty.

And this is true only for my jboss instance - on jboss all data in versionhistory is empty. If i run this example standalone - all work fine.(
repository.xml is the same.
What is thet means?
Thanks,
Stas

So it seems like jackrabbit-jca or JBoss make the difference... but I
am wondering what kind of problem would only affect binary properties
in versioned nodes. Are you using transactions? And could you post the
repository.xml?

I deploy jackrabbit-server.rar for test and then deploy jcr-ds.xml

<connection-factories>
    <tx-connection-factory>
                <jndi-name>jcr/local</jndi-name>
                <xa-transaction/>
                <rar-name>jackrabbit-server.rar</rar-name>
                <connection-definition>javax.jcr.Repository</connection-definition>
                <config-property name="homeDir" type="java.lang.String">/temp/jackrabbit</config-property>
                <config-property name="configFile" type="java.lang.String">classpath:repository.xml</config-property>
                <config-property name="bindSessionToTransaction" type="java.lang.Boolean">true</config-property>
    </tx-connection-factory>
</connection-factories>

I don't touch reposotory.xml. This is text from it:

<Repository>
    <FileSystem class="org.apache.jackrabbit.core.fs.local.LocalFileSystem">
       
    </FileSystem>
    <Security appName="Jackrabbit">
        <AccessManager class="org.apache.jackrabbit.core.security.SimpleAccessManager">
        </AccessManager>
        <LoginModule class="org.apache.jackrabbit.core.security.SimpleLoginModule">  
           
        </LoginModule>
    </Security>
    <Workspaces rootPath="${rep.home}/workspaces" defaultWorkspace="default"/>
    <Workspace name="${wsp.name}">
        <FileSystem class="org.apache.jackrabbit.core.fs.local.LocalFileSystem">
           
        </FileSystem>
        <PersistenceManager class="org.apache.jackrabbit.core.persistence.bundle.DerbyPersistenceManager">
         
         
        </PersistenceManager>
        <SearchIndex class="org.apache.jackrabbit.core.query.lucene.SearchIndex">
           
        </SearchIndex>
    </Workspace>
    <Versioning rootPath="${rep.home}/version">
        <FileSystem class="org.apache.jackrabbit.core.fs.local.LocalFileSystem">
           
        </FileSystem>
        <PersistenceManager class="org.apache.jackrabbit.core.persistence.bundle.DerbyPersistenceManager">
         
         
        </PersistenceManager>
    </Versioning>
    <SearchIndex class="org.apache.jackrabbit.core.query.lucene.SearchIndex">
       
    </SearchIndex>
</Repository>

And then i get Repository like this:

InitialContext ctx = new InitialContext();
Repository repository = (Repository) ctx.lookup("java:jcr/local");



What is wrong?

Thanks,
Stas

Looks like you are using transactions implicitly. Could be a bug in
Jackrabbit's XA transactions implementation when it comes to
versioning of binary properties. Does anyone that is familiar with
this code knows more?

You are right. We changed  <tx-connection-factory> for  <no-tx-connection-factory>. This is all.)) Thx you.
