Strange path problem (revisited)
by Kristian Kankainen 01 Jun '15

01 Jun '15

Hello! I noticed that I get different results if I visit the following two urls: http://myhost.domain/webappname/ http://myhost.domain/webappname The only difference is the trailing slash. My RESTXQ has a path for '/' but not for ''. My setup is with Tomcat. The difference seems to be the basepath for the webapp. Static files etc are not found. This also applies for the BaseX DBA: http://myhost.domain/webappname/dba/login resolves correctly http://myhost.domain/webappname/dba/login/ doesn't find it's static files etc. For my own webapp, it's the other way around --- with the trailing slash everything works fine, without it the static files etc aren't found. Is it yet another Tomcat problem or can it be reproduced on your setups? Cheers! Kristian

Since this conversation accidentally went off-list somewhere on it's way... I am happy to announce that Christian now has solved the Tomcat problem. Cheers!

rest:resource vs db:list-details resource
by James Ball 01 Jun '15

01 Jun '15

Hello, If I use the REST interface to get details of the resources in a database (http://localhost:8984/rest/TEST-DATABASE for example) the result is rest:resource elements that include size. <rest:resource type="xml" content-type="application/xml" size="46”> I assumed that db:list-details was the XQuery equivalent but the resource elements it returns do not include size. <resource raw="false" content-type="application/xml" modified-date="2015-05-31T17:12:32.907Z”> I’m sure it is staring me in the face but I can’t work out how to get the size value from within XQuery. Can someone point me in the right direction? I’m trying to do some database pruning based on the size of the documents which would be very easy if I had rest:resource elements. Many thanks, James

Issues with new json xml function and copy clause
by James Wright 29 May '15

29 May '15

I am having issues with the new json-to-xm functions with a copy clause. I would expect the following query to work: *let $json := '{"age":23,"name":"Bob"}'return copy $out := json-to-xml($json) modify delete node $out//*[@key='age'] return xml-to-json($out)* Instead I get an error when calling xml-to-json: [FOJS0006] Element 'map' has invalid namespace: ''. It appears the copy clause is dropping the namespace on the map object. Is this something I must manually prevent or a bug? Thanks for all your time. - James

Multiple BaseX Tomcat webapps
by Kristian Kankainen 28 May '15

28 May '15

Hello! I previously had BaseX 8.1.1 working as a Tomcat webapp and it all worked fine. I know tried to simply put BaseX82.war as another webapp, but the second webapp seems to connect to the BaseX instance in the first webapp. For example: the address http://tomcat.myhost.ee/BaseX82/rest/ lists all the databases that are in http://tomcat.myhost.ee/BaseX811/ even though the new BaseX82 instance should be empty. I have problems understanding if this concerns BaseX configuration or Tomcat configuration... Which files should I check? Looking at the both's webapps' WEB-INF/web.xml they seem logically fine to me. Best regards Kristian K

Creating a batch BaseX program
by Noam Green 28 May '15

28 May '15

Hi, I'm new to BaseX, so apologize if this is a repetitive question. I have created an XQuery which currently runs on a specific XML file. What I'd like to do is to be able to create a batch command, which would receive as input a different XML source file, run the XQuery command, and save the results in a CSV file. Is there a way to do such a process? Thanks, Noam

SQL Module
by James Wright 27 May '15

27 May '15

Hey Everyone, I am having issues with using the Oracle 1.7 JDBC driver. I copied the ojdbc7.jar file into the lib directory Ran the basexgui.bat to add to class path Tried to run this script: let $conn := sql:init('jdbc:oracle:thin:pnm/pnm@orc1n.giants') return (sql:execute($conn, 'SELECT owner, table_name FROM dba_tables '), sql:close($conn)) It states that it cannot initialize the jdbc:oracle:thin driver. Any ideas why that would be? Am I missing something? - James
