Hi List,

I am new to this forum. I am trying to use dbwsbuilder to generate a web service from a table. I got the generated .war file and loaded to the tomcat6. When I request the address it gives below error

_dbws.DBWSProvider is not available


I searched net and found below link:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=307897

It says that it is a bug and to recover it you have to compile \org\eclipse\persistence\tools\dbws\ProviderPackager.java with ASM 3.1 or 3.2

Every thing is ok till now, but i cannot find the source code of the dbwsbuilder.

How can I find it?

thanks in advance,

-halil.

Hi David,

Sorry for late response.

I downloaded the latest version and compiled with ant successfully. But, now i have a different problem. Here is the list of my steps.


1. download eclipselink.runtime-2.5.0-M6
2. setting up ant 1.7.1 maven 3.0.4 and jdk 6.update.38
3. ant -f antbuild.xml
4. ant -f antbuild.xml build-distribution
5. copy eclipselink.zip and unzip to an empty directory.
6. cd ${eclipselink-workdir}/eclipselink/utils/dbws
7.create dbws builder xml file as below

<?xml version="1.0" encoding="UTF-8"?>
<dbws-builder xmlns:xsd="{2001-XMLSchema-url-address}">
<properties>
<property name="projectName">test11</property>
<property name="logLevel">fine</property>
<property name="username">halil</property>
<property name="password">123456</property>
<property name="url">jdbc:mysql://localhost:3306/testdb</property>
<property name="driver">com.mysql.jdbc.Driver</property>
<property name="platformClassname">org.eclipse.persistence.platform.database.MySQLPlatform</property>

<property name="dataSource">jdbc/test10-glf-ds</property>
<property name="wsdlLocationURI">{my-wsdl-address}</property>

</properties>
<table
catalogPattern="%"
tableNamePattern="table1"
/>
</dbws-builder>


8. run below command

./dbwsbuilder.sh -builderFile testdb-mysql-dbws-builder.xml -stageDir testdb_out -packageAs glassfish

9. copy newly builded jar file into glassfish3/modules directory. jar list is below (i added also mysql driver)

-rw-r--r-- 1 halil halil 832960 Feb 4 02:43 mysql-connector-java-5.1.22-bin.jar

10. open constructed war (at step Cool and fix the files
10.1 fix the dbws-or.xml file path as below

<primary-project xsi:type="xml">META-INF/eclipselink-dbws-or.xml</primary-project>

10.2 add below xml fragment into the session tag

<session xsi:type="database-session">
<name>test-dbws-ox-session</name>
<logging xsi:type="eclipselink-log">
<log-level>all</log-level>
</logging>
<primary-project xsi:type="xml">META-INF/eclipselink-dbws-ox.xml</primary-project>
</session>

10.3 there is xml-bindings-list tag in the dbws-ox.xml file but it is not defined in the xsd file. and i changed the dbws-ox.xml as below. Before changing, i was getting the error ( A descriptor with default root element {http://www.eclipse.org/eclipselink/xsds/persistence/oxm}xml-bindings-list was not found in the project)


<xml-bindings package-name="test11" xmlns="http://www.eclipse.org/eclipselink/xsds/persistence/oxm">

<xml-schema namespace="urn:test11" element-form-default="QUALIFIED"/>
<java-types>
<java-type xml-accessor-type="FIELD" name="Table1">
<xml-type namespace="urn:test11" name="table1Type"/>
<xml-root-element namespace="urn:test11" name="table1Type"/>
<java-attributes>

<xml-schema-type name="string"/>
</xml-element>
</java-attributes>
</java-type>
</java-types>
</xml-bindings>


11. package as new war deploy it to glassfish as below
./bin/asadmin deploy /home/halil/projects/eclipselink-workdir/fix-war/test11.war

12. test the web servie with soapui and got the below exceptions


13. now, currently, i am getting the below error

bla. bla. bla.



Lastly, to be able to see the exceptions, i change the source code. I added below lines into the file ./dbws/org.eclipse.persistence.dbws/src/org/eclipse/persistence/internal/xr/XRServiceFactory.java

aroung line 317.

for (String prefix : META_INF_PATHS) {
String searchPath = prefix + sessionsFile;
System.out.println("halil:"+searchPath);
XRSessionConfigLoader loader = new XRSessionConfigLoader(searchPath);
loader.setShouldLogin(false);
try {
found = loader.load(sessionManager, projectLoader);
} catch (RuntimeException e) { /* ignore */
e.printStackTrace();
}
if (found) {
break;
}
}






It seems that I need some xmlns decleration in the dbws-ox.xml file. But, i dont know. Could you please help me?



best,


-halil.

It looks like the attempt to load the OXM metadata project is failing; when this occurs (meaning we can't load the OX project via JAXB metadata) we attempt to load the OX project via legacy deployment XML format (this is done to provide backwards compatibility). What I'd suggest is that you revert 'META-INF/eclipselink-dbws-ox.xml' to it's original format, then add some debug statements in the code that tries to load the OX project via dynamic JAXB to see how far it gets.

XRServiceFactory.loadOXMetadata(Classloader)

Note that his could also be caused by a mismatch in EclipseLink versions between your client code and the app server; if the client side is generating the OX project in JAXB metadata format but the server side code is expecting the legacy deployment XML format this will occur. Please make sure the same JAR versions are being used on the client and server.
