restSQL战争部署问题

Question

I'm trying to deploy restSQL in my local tomcat installation based on this link.

From my tomcat webapps folder:

webapps\\restsql-0.8\\WEB-INF\\classes\\resources\\properties

I have modified 'default-restsql.properties' to set the correct database connections

and retained the property 'sqlresources.dir=/resources/xml/sqlresources' while adding/creating the folder on that location.

I also modified in web.xml:

<context-param>
    <param-name>org.restsql.properties</param-name>
    <param-value>/WEB-INF/resources/properties/default-restsql.properties</param-value>
</context-param>

I'm quite sure that the default.restsql.properties is loaded since when I access this resource:

http://localhost:8080/restsql-0.8/conf

I get this response:

Properties loaded from /resources/properties/default-restsql.properties:
log4j.configuration = resources/properties/default-log4j.properties
org.restsql.security.Authorizer = org.restsql.security.impl.AuthorizerImpl
org.restsql.core.RequestLogger = org.restsql.core.impl.RequestLoggerImpl
**sqlresources.dir = /resources/xml/sqlresources**
database.driverClassName = com.mysql.jdbc.Driver
logging.config = resources/properties/default-log4j.properties
database.user = root
org.restsql.core.Factory.ResponseSerializerFactory = org.restsql.core.impl.ResponseSerializerFactoryImpl
org.restsql.core.SqlBuilder = org.restsql.core.impl.SqlBuilderImpl
database.password = root
org.restsql.core.Factory.ConnectionFactory = org.restsql.core.impl.ConnectionFactoryImpl
org.restsql.core.SqlResourceMetaData = org.restsql.core.impl.SqlResourceMetaDataMySql
org.restsql.core.HttpRequestAttributes = org.restsql.core.impl.HttpRequestAttributesImpl
logging.facility = log4j
response.useXmlSchema = false
org.restsql.core.Factory.RequestFactory = org.restsql.core.impl.RequestFactoryImpl
database.url = jdbc:mysql://localhost:3306/
logging.dir = /var/log/restsql
org.restsql.core.Factory.SqlResourceFactory = org.restsql.core.impl.SqlResourceFactoryImpl
request.useXmlSchema = false
response.useXmlDirective = false
org.restsql.core.Factory.RequestDeserializerFactory = org.restsql.core.impl.RequestDeserializerFactoryImpl

Properties using defaults:
org.restsql.core.Factory.Connection = org.restsql.core.impl.ConnectionFactoryImpl
java.util.logging.config.file = resources/properties/default-logging.properties
request.useXmlDirective = false
org.restsql.properties = /resources/properties/default-restsql.properties

However when I access this resources

http://localhost:8080/restsql-0.8/res/

I get this response:

SQL Resources directory /resources/xml/sqlresources does not exist ... please correct your sqlresources.dir property in your restsql.properties file

Although the folder do exist: webapps\\restsql-0.8\\WEB-INF\\classes\\resources\\xml\\sqlresources

What could be the problem?

Answer 1

Sorry you're having trouble with deployment. restSQL requires an absolute path to the main properties file. It does not have the capability to search its WAR file or exploded web app dir, other than look in the classpath for the default.

Most paths are to other files, referenced in the main restSQL properties files have to be absolute. The only one that is relative is the logging.config. Please have a look at Deployment for all the nitty-gritty deployment instructions.

Hope that does the trick for you.

When it rains it pours?

Sounds like you had trouble running one of the database create scripts? Is that in restsql-sdk/WebContent/database/postgresql? Did you have errors running create-sakila.bat? Perhaps your psql executable is not in your path. You can edit the file to add it to your PATH environment variable temporarily.

You won't get any 5xx errors if the resource query returns no data. You will get a 200 with an empty readResponse document.

Your problem is likely a resource definition metadata issue. Is country_id from the country table? Is country defined as a table in the metadata? Can you post the resource definition?

Have you looked over the SQL resource rules at http://restsql.org/doc/SqlResourceRules.html ? Sorry, SQL Functions and views are not allowed. You must use plain old columns and tables.
