Hi everyone:
I'm new to Scout and also to OSGI. I tried to folow the tutorial in the wiki: Write_a_jdbc_connection_bundle but using jTDS driver:
Created a plugin project with java src : org.eclipse.scout.rt.jdbc.jtds125 with a generated Activator
created a lib folder and placed the jTDS jar:jtds-1.2.5.jar
Created 2 packages:
org.eclipse.scout.rt.services.common.jdbc
org.eclipse.scout.rt.services.common.jdbc.style
placed the folowing classes respectivly:
package org.eclipse.scout.rt.services.common.jdbc;
import org.eclipse.scout.rt.server.services.common.jdbc.AbstractSqlService;
import org.eclipse.scout.rt.server.services.common.jdbc.style.ISqlStyle;
import org.eclipse.scout.rt.services.common.jdbc.style.JtdsSqlStyle;
public class AbstractJtdsSqlService extends AbstractSqlService {
@Override
protected String getConfiguredJdbcDriverName() {
return "net.sourceforge.jtds.jdbc.Driver";
}
@Override
protected String getConfiguredJdbcMappingName() {
return "jdbc:jtds:<server_type>://<server>[:<port>][/<database>]";
}
@Override
protected Class<? extends ISqlStyle> getConfiguredSqlStyle() {
return JtdsSqlStyle.class;
}
}
and:
package org.eclipse.scout.rt.services.common.jdbc.style;
import java.sql.Connection;
import java.sql.SQLException;
import java.sql.Statement;
import org.eclipse.scout.rt.server.services.common.jdbc.style.AbstractSqlStyle;
public class JtdsSqlStyle extends AbstractSqlStyle {
/**
*
*/
private static final long serialVersionUID = -6139827987362401678L;
@Override
public String getConcatOp() {
return "+";
}
@Override
public String getLikeWildcard() {
return "%";
}
@Override
protected int getMaxListSize() {
return 1000;
}
@Override
public boolean isLargeString(String s) {
return (s.length() > 4000);
}
@Override
public boolean isBlobEnabled() {
return true;
}
@Override
public boolean isClobEnabled() {
return true;
}
@Override
public String createDateTimeIsNow(String attribute) {
return "TRUNC(" + attribute + ", 'MI')=TRUNC(SYSDATE, 'MI')";
}
@Override
public String createDateTimeIsNotNow(String attribute) {
return "TRUNC(" + attribute + ", 'MI')!=TRUNC(SYSDATE, 'MI')";
}
@Override
public void testConnection(Connection conn) throws SQLException {
Statement testStatement = null;
try {
testStatement = conn.createStatement();
testStatement.execute("SELECT count(1) FROM dbo.sysobjects");
} finally {
if (testStatement != null)
try {
testStatement.close();
} catch (Throwable t) {
}
}
}
}
then exported the 2 packages and added the jar to classpath.
The MANIFEST file is:
Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: Jtds125
Bundle-SymbolicName: org.eclipse.scout.rt.jdbc.jtds125;singleton:=true
Bundle-Version: 1.0.0.qualifier
Bundle-Vendor: Diogo Duarte
Bundle-RequiredExecutionEnvironment: JavaSE-1.6
Bundle-ClassPath: lib/jtds-1.2.5.jar
Require-Bundle: org.eclipse.scout.rt.server;bundle-version="3.7.0",
org.eclipse.core.runtime;bundle-version="3.5.0"
Eclipse-RegisterBuddy: org.eclipse.scout.rt.server,pt.diogoduarte.wforce.server
Export-Package: net.sourceforge.jtds.jdbc,
net.sourceforge.jtds.jdbc.cache,
net.sourceforge.jtds.jdbcx,
net.sourceforge.jtds.jdbcx.proxy,
net.sourceforge.jtds.ssl,
net.sourceforge.jtds.util,
org.eclipse.scout.rt.services.common.jdbc,
org.eclipse.scout.rt.services.common.jdbc.style
Bundle-Activator: org.eclipse.scout.jdbc.jtds125.Activator
Bundle-ActivationPolicy: lazy
Afterwards i opened the server package in my ScoutProject and added my plugin to the dependencies:
Require-Bundle: org.eclipse.core.runtime,
pt.diogoduarte.wforce.shared,
org.eclipse.scout.rt.server,
org.eclipse.scout.http.servletfilter,
org.eclipse.equinox.http.registry,
org.eclipse.scout.rt.jdbc.jtds125
I created a
package pt.diogoduarte.wforce.server.services.common.sql;
import java.sql.Connection;
import org.eclipse.scout.commons.annotations.ConfigOperation;
import org.eclipse.scout.commons.annotations.Order;
import org.eclipse.scout.commons.exception.ProcessingException;
import org.eclipse.scout.rt.server.services.common.jdbc.style.ISqlStyle;
import org.eclipse.scout.rt.services.common.jdbc.AbstractJtdsSqlService;
import org.eclipse.scout.rt.services.common.jdbc.style.JtdsSqlStyle;
import org.eclipse.scout.service.IService2;
public class TesteSqlService extends AbstractJtdsSqlService implements IService2 {
@Override
protected String getConfiguredJdbcDriverName() {
return "net.sourceforge.jtds.jdbc.Driver";
}
@Override
protected String getConfiguredJdbcMappingName() {
return "jdbc:jtds:sqlserver://sqlserver.scoprolumba.pt:1433/erpscopro";
}
@Override
protected String getConfiguredPassword() {
return "xxxx";
}
@Override
protected Class<? extends ISqlStyle> getConfiguredSqlStyle() {
return JtdsSqlStyle.class;
}
@Override
protected String getConfiguredUsername() {
return "sa";
}
}
Then binded to a PageTable throw a StandardOutlineService
and a getContacts() method:
but when i run the server and client get the folowing message in the server log:
!ENTRY org.eclipse.scout.service 4 0 2012-10-21 16:23:39.045
