Re: Native SQL Query
Hi, I just cross checked with a native SQL query on Slice. It does run. Though the new addition lacked thorough testing, I would not expect the error you have reported provided the new changes are applied in your environment. To ensure that the change is available in your environment, please do the following: 1. $ java -jar /path/to/openjpa.jar this will print the SVN reversion number openjpa is built with 2. Check whether following class is present in the distribution (because this is the newly added class) org.apache.openjpa.slice.jdbc.DistributedSQLStoreQuery - Pinaki Poddar Chair, Apache OpenJPA Project -- View this message in context: http://openjpa.208410.n2.nabble.com/Native-SQL-Query-tp6432918p6646315.html Sent from the OpenJPA Users mailing list archive at Nabble.com.

Re: Native SQL Query
I dug around the code a little bit and native queries don't work with slice... I'm not sure if it is a simple bug to fix, or if it will take a large effort to fix. Can I have you open a JIRA[1] for this bug?

Re: Native SQL Query
Additional information I found, is that this only happens in a Distributed
environment (Slice). Below is the method that is returning null for
ExpressionParser. At this point in execution, language is openJpa.SQL.
There doesn't seem to be an ExpressionParser mapped to this language.
public StoreQuery newQuery(String language) {
ExpressionParser parser =
QueryLanguages.parserForLanguage(language);
DistributedStoreQuery ret = new DistributedStoreQuery(this, parser);
for (SliceStoreManager slice : _slices) {
ret.add(slice.newQuery(language));
}
return ret;
}
Is this a bug or is native queries not going to be supported in a sliced
environment?

Re: Native SQL Query
Which properties do you have in persistence.xml? A reply on Nabble (not accepted by the mailing list yet) asserts that this only happens with slice. If that's the case we can look into reproducing the problem outside of your container environment.

Re: Native SQL Query
Thanks for the reply. Yes you are right, we are using a distributed
environment (Slice) and we did find out that this only happens when we are
using slice. Below is the method that is returning null for
ExpressionParser. At this point in execution, language is openJpa.SQL.
There doesn't seem to be an ExpressionParser mapped to this language.
public StoreQuery newQuery(String language) {
