Hi,
i dont know about the other problem but u can do the following:
log.debug("[BaseX] executing query:"+query); ClientSession cSes = new ClientSession(serverNameBaseX, Integer.valueOf(portBaseX), user, pass); cSes.setOutputStream(System.out); ClientQuery cQuery = cSes.query(query); String res = cQuery.execute(); String info = cQuery.info(); ß This res only stores the execution time and not the result of the query, so it is useless (for me :-) ) cQuery.close();

Hi,
I’ve downloaded last BaseX version from the download page and what I’ve done it is just put the BaseX76.war into webapps deployment directory of Tomcat.
As far as I know, it has deployed correctly, since I can make REST requests successfully like http://MiServer/BaseX76/rest?command=show+users.
The problem comes when I try to access it from my Java Application, where I’ve tried with two methods: JavaClient and XQJ. With JavaClient it works, but with XQJ the response is always the same (log from [TOMCAT_DEPLOYMENT_DIRECTORY]/BaseX76/data/.logs):
13:32:40.053 172.24.41.93:59521 admin ERROR Improper use? Potential bug? Your feedback is welcome: Contact: basex-talk@mailman.uni-konstanz.de Version: BaseX 7.6 Java: Oracle Corporation, 1.7.0 OS: Linux, i386 Stack Trace: java.lang.NoClassDefFoundError: org/basex/index/value/DiskValues org.basex.data.DiskData.<init>(DiskData.java:88) org.basex.core.cmd.Open.open(Open.java:70) org.basex.core.cmd.Open.run(Open.java:36) org.basex.core.Command.run(Command.java:342) org.basex.core.Command.exec(Command.java:321) org.basex.core.Command.execute(Command.java:78) org.basex.server.ClientListener.run(ClientListener.java:145) 453.12 ms
The block of Java code where the Exception is thrown is the following (for the case of XQJ):
log.debug("[BaseX] executing query:"+query); XQDataSource xqs = new BaseXXQDataSource(); xqs.setProperty("databaseName", dbName); xqs.setProperty("serverName", serverNameBaseX); xqs.setProperty("port", portBaseX); xqs.setProperty("user", usuario); xqs.setProperty("password", clave); xqs.setLogWriter(new PrintWriter(System.out, true)); XQConnection xqc = xqs.getConnection(); ß Here is where the Exception is thrown XQExpression xqe = xqc.createExpression(); XQSequence xq = xqe.executeQuery(query); StringBuilder res = new StringBuilder(); while (xq.next()) { res.append(xq.getItemAsString(null)); } log.debug("[BaseX] result:"+res); xqc.close();It seems that it is not finding the jars inside the WAR where DiskData class is located, but I’ve entered into the Tomcat directory where the WAR has been deployed (/BaseX76/WEB-INF/lib) and all of them are there:

Any ideas?. Other projects deployed into that server worked without any problem. I know that I could use JavaClient method for accessing but then the problem is that I cannot recover the result of the query execution, while with XQJ I can:
JavaClient: log.debug("[BaseX] executing query:"+query); ClientSession cSes = new ClientSession(serverNameBaseX, Integer.valueOf(portBaseX), user, pass); cSes.setOutputStream(System.out); ClientQuery cQuery = cSes.query(query); cQuery.execute(); String res = cQuery.info(); ß This res only stores the execution time and not the result of the query, so it is useless (for me :-) ) cQuery.close();
XQJ: XQSequence xq = xqe.executeQuery(query); ß Instead, this do stores the result of the query (exactly what I want)
Thank you and best regards,
