I used that driver.

C:\Program Files\Java\jdk1.7.0_07\bin\java

May be jdk1.7.0_07 the problem?

config.properties "creates" the table:

B4X:
#Lines starting with '#' are comments.
#Backslash character at the end of line means that the command continues in the next line.

# - MySql
#DriverClass=com.mysql.jdbc.Driver
#JdbcUrl=jdbc:mysql://localhost/test?characterEncoding=utf8

# - SQL Server
#DriverClass=net.sourceforge.jtds.jdbc.Driver
#JdbcUrl=jdbc:jtds:sqlserver://<database server ip>/<database>

# - SQLite
DriverClass=org.sqlite.JDBC
JdbcUrl=jdbc:sqlite:C:/temp/test.db

User=root
Password=
ServerPort=17178

#If Debug is true then this file will be reloaded on every query.
#This is useful if you need to modify the queries.
Debug=true

sql.create_table=CREATE TABLE animals (\
    id INT NOT NULL AUTO_INCREMENT,\
    name CHAR(30) NOT NULL,\
    image BLOB,\
    PRIMARY KEY (id))
sql.insert_animal=INSERT INTO animals VALUES (null, ?,?)
sql.select_animal=SELECT name, image FROM animals WHERE name = ?

c3p0.idleConnectionTestPeriod=600
c3p0.checkoutTimeout=20000
c3p0.minPoolSize=1
c3p0.maxPoolSize=1

runRLC.cmd
B4X:
cd "C:\Program Files (x86)\Java\jre7\bin\"
java.exe -Xmx256m -cp .;libs\*;jdbc_driver\*
anywheresoftware.b4a.remotedatabase.RemoteServer
pause

I'm having trouble with the RDC-Client. I turn my firewall off - temporarily. When I issue: http://192.168.1.122:17178/?method=test from my browser I get.

RemoteServer is running (Thu Feb 27 10:04:07 EST 2014)
Connection successful.

The StartJob() sub may have problems with XML formatting??

B4X:
Private Sub StartJob(j As HttpJob, MemoryStream As OutputStream, Tag As Object) As OutputStream
    j.Initialize("DBRequest", mTarget)
    j.Tag = Tag
    MemoryStream.InitializeToBytesArray(0)
    Dim compress As CompressedStreams
  
    'When I look at MemoryStream below it says the XML is improperly formatted.
    Dim out As OutputStream = compress.WrapOutputStream(MemoryStream, "gzip")

In Log:
Error:...Connection to http://192.168.1.122:17178 refused

I realize I am using persons.db. I created one table called animals and am trying to issue a Select query.
config.properties and c3po.properties are in an attached zip. Your help is appreciated. Thanks, JD.
