Stein Kåre Skytteren updated SOLR-1794:
---------------------------------------
Attachment: FieldReaderDataSource.java
A fixed version of org.apache.solr.handler.dataimport.FieldReaderDataSource
Change line 89 and 110 to use getMethod instead of getDeclaredMethod.
This works for us on Weblogic 10.3.2.
> Dataimport of CLOB fields fails when getCharacterStream() is defined in a
> superclass

> Key: SOLR-1794
> URL: https://issues.apache.org/jira/browse/SOLR-1794
> Project: Solr
> Issue Type: Bug
> Components: contrib - DataImportHandler
> Affects Versions: 1.4
> Environment: Oracle WebLogic 10.3.2
> Reporter: Gunnar Gauslaa Bergem
> Attachments: FieldReaderDataSource.java
>
>
> When running Solr on WebLogic application server 10.3.2, the dataimport for
> CLOB fields are failing. Line 109 in FieldReaderDataSource.java illustrates
> the problem:
> Method m = clob.getClass().getDeclaredMethod("getCharacterStream");
> Since getDeclaredMethod instead of getMethod is used, the
> getCharacterStream() method will not be found if it is defined in a
> superclass of clob. This is exactly what
> happens in e.g. WebLogic 10.3.2, since the object returned is a dynamically
> created wrapper class called Clob_oracle_sql_CLOB. This class does not define
> getCharacterStream(), but it inherits from another class that does. This
> problem will also occur in other places where getDeclaredMethod used in
> conjunction with the CLOB
> or BLOB datatypes.
> Stacktrace:
> org.apache.solr.handler.dataimport.DataImportHandlerException: Unable to get
> reader from clob Processing Document # 1
