From: Sara on 27 Jun 2010 12:18 I tried to use java-connector to connect to mysql in linux environment but after saving 50 records and sometimes alittle more matlab returns me error that cannot load the java connector driver however I close the connection for each insertion and again open it for new insertion , most of the time the error message is like this : One or more output arguments not assigned during call to "getValidConnection". Error in ==> database.database at 140 connection.Handle = getValidConnection(conn,connectionVector); Error in ==> database1 at 23 dbConn = database(dbName, user , password, jdbcDriver, jdbcString); this is a general error that I get and I couldn't find any solution and it is two days that I'm working on that I used different java connectors such as mysql.com connector, sun, openjd but nothing was changed. I even changed the logintime but again nothing was changed. I used the code like the following link http://www.etf-central.com/using-matlab%2526%2523039%3Bs-database-toolbox-mysql-connector/j-214 of course I even give it the explicit path for jar file such as /usr/.../ but nothing was changed. any guide would be helpful

From: sara on 28 Jun 2010 11:23 Hello, Thank you for your response. but I use matlab in Linux environment and there is no such file in a path you mentioned. there is toolbox directory but not that file in that directory. so I cannot change anything and the result of your command >> javaclasspath STATIC JAVA PATH /home/rafiee/Installed/matlab/java/patch

BTW, did you look into the matlabroot and then inside the toolbox subdirectory etc.. etc..? You have to find the classpath.txt file and add manually the directory as I did: C:\Users\public\Desktop\mysql-connector-java-5.1.9\mysql-connector-java-5.1.9-bin.jar You can use the rdir submission (search on FEX) and look for: rdir([matlabroot '\**\classpath.txt']) Oleg
