Is there any java API/java plugin which can generate Database ER diagram when java connection object is provided as input.
Ex: InputSream generateDatabaseERDiagram(java connection object)// where inputsream will point to generated ER diagram image
The API should work with oracle,mysql,postgresql?
I was going through schemacrawler(http://schemacrawler.sourceforge.net/) tool but didint got any API which could do this.
If no API like this is there then let me know how can write my own API? I want to generate ER diagram for all the schema in a database or any specific schema if the schema name is provided as input.
It will be helpful if you show some light on how to achieve this task.
If I understood you question correctly, you might take a look at: JGraph
This is an old question but in case anyone else stumbles across it as I did when trying to do the same thing I eventually figured out how to generate the ERD using Schemacrawler's java API.
//Get your java connection however
Connection conn = DriverManager.getConnection("DATABASE URL");
SchemaCrawlerOptions options = new SchemaCrawlerOptions();
// Set what details are required in the schema - this affects the
// time taken to crawl the schema
options.setSchemaInfoLevel(SchemaInfoLevelBuilder.standard());
// you can exclude/include objects using the options object e.g.
//options.setTableInclusionRule(new RegularExpressionExclusionRule(".*qrtz.*||.*databasechangelog.*"));
GraphExecutable ge = new GraphExecutable();
ge.setSchemaCrawlerOptions(options);
String outputFormatValue = GraphOutputFormat.png.getFormat();
OutputOptions outputOptions = new OutputOptions(outputFormatValue, new File("database.png").toPath());
ge.setOutputOptions(outputOptions);
ge.execute(conn);
This still requires graphviz to be installed and on the path to work.

Can anyone give me at least one idea to how can I connect java with protoge?
how can I access OWL using jena API in java?!
The Jena website has plenty of tutorials available. If you have difficulties getting started, please post the code that does not work and we'll help you along.
First tutorial here
// some definitions
static String personURI = "http://somewhere/JohnSmith";
static String fullName = "John Smith";
// create an empty Model
Model model = ModelFactory.createDefaultModel();
// create the resource
Resource johnSmith = model.createResource(personURI);
// add the property
johnSmith.addProperty(VCARD.FN, fullName);
In order to make this work, you'll need the right imports. Assuming that the Java technicalities are not a problem, this example shows how to create a statement and add it to a model, i.e., an rdf file.
From the same page you can get to more complex material, including OWL tutorials.
You have not mentioned which task you're trying to carry out. Can you describe it?
Ok, I am reposting this question because it really drives me crazy.
I have enterprise.wsdl downloaded from salesforce and generated to some jars.
I build path those jars to my Android project in Eclipse.
Here is my code:
ConnectorConfig config = new ConnectorConfig();
config.setAuthEndpoint(authEndPoint);
config.setUsername(userID);
config.setPassword(password + securityToken);
config.setCompression(true);
con = new EnterpriseConnection(config);
con.setSessionHeader(UserPreference.getSessionID(mContext));
String sql = "SELECT something FROM myNameSpace__myCustomObject__c";
con.query(sql);
but it returns me this error:
[InvalidSObjectFault [ApiQueryFault [ApiFault
exceptionCode='INVALID_TYPE' exceptionMessage='sObject type 'abc__c'
is not supported.'] row='-1' column='-1' ]]
I am pretty sure that my userID has been assigned with profile that has read, edit access to that custom object.
My code also can query standard object.
Anyone can advise me what could be wrong?
From what I know there are three reasons it may give this error.
1. User permission which you said is setup correctly.
2. Do you have the custom object deployed to the org where you are trying to establish the connection?
3. Check the enterprise WSDL if it contains the custom object name which you are trying to query.
Hope it helps.
I am trying to display the result of a Mondrian query using JPivot. Many examples are showing how to use the tag library for JSP but I need to use the Java API, I looked at the documentation but I cannot understand how to use it to display the results in the table. Here is my code
Query query = connection.parseQuery(mdxQuery);
Result result = connection.execute(query);
result.print(new PrintWriter(System.out,true));
I would like to know if I can use the result object to build the jpivot table.
Thanks in advance!
First of all, using JPivot
is a pretty bad idea.
It was discontinued back in 2008.
There is a good project which is intended to replace the JPivot called Pivot4j. Despite it is currently under development (0.8 -> 0.9 version), Pivot4j can actually do the business.
However, if we're talking about your case:
result.print(new PrintWriter(System.out,true));
This string prints the HTML code with OLAP cube into your System.out.
You can write the HTML code in some output stream (like FileOuputStream), and then display it.
OutputStream out = new FileOutputStream("result.html");
result.print(new PrintWriter(out, true));
//then display this file in a browser
However, if you want to have the same interface as in JPivot, I don't think there is an easy way to do it without .jsp. In these case I strongly recommend you to try Pivot4j.
Good luck!
I am new to BO, I need to find universe name and the corresponding metadata information like(Table name, column names, join conditions etc...). I am unable to find proper way to start. I looked with Data Access SDK, Semantic SDk.
Can any one please provide me the sample code or procedure for starting..
I googled a lot but i am unable to find any sample examples
I looked into this link but that code will work only on R2 Server.

Help is Highly Apprecitated.....
Assuming you're talking about IDT based universes, you'll need to code some Java. The JavaDoc for the API is available here.
In a nutshell, you do something like this:
SlContext context = SlContext.create() ;
LocalResourceService service = context.getService(LocalResourceService.class) ;
String blxFile = service.retrieve("universe.unx","output directory") ;
RelationalBusinessLayer businessLayer = (RelationalBusinessLayer)service.load(blxFile);
RootFolder rootFolder = businessLayer.getRootFolder() ;
Once you have a hook on the rootFolder, you can use the getChildren() method to drill into the folder structure and access the various subfolders/business objects available.
You may also want to check the CmsResourceService class to access universes stored on the repository.
To get the information you are after will require a 2 part solution. Part 1 use the Rebean SDK looking at WebI reports for the Universe and object names being used with in it.
Part 2 is to break out your favorite COM programming tool, since I try to avoid COM I use the Excel Macro editor, and access the BusinessObjects Designer library. Main code snippets that I currently have are:
Dim boUniv As Designer.Universe
Dim tbl As Designer.Table
For Each tbl In boUniv.Tables
Debug.Print tbl.Name
Next tbl
This prints all of the tables in a universe.
You will need to combine the 2 parts on your own for a dependency list between WebI reports and Universes.
The requirement I receive is to model some existing content available on a SQL Server database using Alfresco content managment so, I create my new content model and it seems to working fine. But I've a problem with multi language: I know in Alfresco is possible for one node add multiple language (how can I do that using Java for a massive load?) but, I used also some aspects that need to be translated.
What do you usually do in that case? I thoug to follow this steps:
Create Eng content and add aspects
Create new child translted and add aspects
Is it correct? How can I make a node Multilingual programmatically (Java) and how can I add the new translate content with aspects? I took a look to Alfresco documentation but, I didn't find it, could you help me to find some documentation or tutorial about that?
UPDATE:
I'm trying to make a content multilangue:
void makeTranslation(Reference contentNodeRef, Locale locale) throws AlfrescoRuntimeException, Exception
{
try {
NodeRef nodeRef = new NodeRef("workspace://SpacesStore/" + contentNodeRef.getUuid());
MultilingualContentServiceImpl multilingualContentServiceImpl = new MultilingualContentServiceImpl();
multilingualContentServiceImpl.makeTranslation(nodeRef, locale);
}
catch (org.alfresco.error.AlfrescoRuntimeException ex) {
throw new AlfrescoRuntimeException(ex.getMessage());
}
catch (Exception ex) {
throw new Exception(ex.getMessage());
}
}
but, makeTranslation raise an nullPoint exception because MultilingualContentServiceImpl it's not initialized correctly. Any suggestion how to initialize it? I've to use spring but, how?
Any suggerstion or reply will be very helpful!
Thanks,
Andrea
You can use MultilingualContentService to add translations. But! I guess your properties should be of type d:mltext (like cm:title and cm:description are) to support multilingual content.
This means if you access alfresco using browser with english language you will see a different description as someone using german language settings in browser. This can be a little confusing because in Share there is (was?) no identifier that the property is multilingual.
If you want your translations to appear everywhere, no matter what kind of language in browser people are using, then the better approach is to define some aspect (for example ex:translatable) with as many properties as you need translations. Then you can programatically (using Java or JavaScript) use search service to find nodes you want and add the aspect to them. Finally you then add properties (translations) of that aspect to the node.
I hope this helps to clear things a bit... :)
