Though this question has asked, the answer could not solve my problem.
I used commons-dbcp2-2.1.1.jarandpostgres jdbc driver. I checked postgresql-8.4-702.jdbc4.jar, postgresql-9.1-901.jdbc4.jar, postgresql-9.2-1004.jdbc4.jar, postgresql-9.3-1103.jdbc4.jar, postgresql-9.3-1103.jdbc41.jar, postgresql-9.4-1202.jdbc4.jar and postgresql-9.4-1202.jdbc41.jar one after another. But none of the implement the isValid function and always throw exception.
org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is java.sql.SQLException: Cannot create PoolableConnectionFactory (Method org.postgresql.jdbc4.Jdbc4Connection.isValid(int) is not yet implemented.)] with root cause
org.postgresql.util.PSQLException: Method org.postgresql.jdbc4.Jdbc4Connection.isValid(int) is not yet implemented.

Any solution?
There is more than one copy of the JDBC driver on the CLASSPATH.
Check the output of org.postgresql.Driver.getVersion ()

im using Eclipse 2018_09 with Vaadin 8. I just created a clean Vaadin Project "myapplication" straight forward. When i create a Vaadin Designer File, "testdesigne.html" and try to open it, the designer is crashing and the file will be closed. It first trys to load the view and crashes after ~5 sec.
When i open the Eclipse Error Log View, i can see following 2 Problems:

anyone any idea how to solve this?
Use Vaadin Designer 2 for Vaadin 8.
I've successfully created an Eclipse-plugin to which I'm adding a command in order to wrap some text with <xsl:text>.
My environment is Win 7 x64, Eclipse Mars, Java 1.7.
In order to implement this feature, I just copy/pasted the org.eclipse.wst.sse.ui.internal.handlers.ToggleLineCommentHandler class which in turn uses some internal classes among which CommentingStrategy.
I'm aware that non API class are marked x-friends in the plugin MANIFEST so that it gives an error at compile time which you can turn off, as Warning in my case...
But then at Runtime I'm getting the below error despite my plugin dependencies is correctly set :
And here is my MANIFEST :
So, is it absolutely forbidden to use eclipse internal classes ??
If so, how can I achieve my purpose which is simply textifying some characters in an XML file by surrounding them with <xsl:text> tag the same way as for the ToggleLineComment.
Thanks for your answers !

I am totally new to liferay.
i have created Liferay portlet in which i need to uploaded document
I used DLUtil.addFile method to upload document from webservice and from local. I also succeed in uploading it. But the problem comes when I tried to upload the document again. It shows com.liferay.portlet.documentlibrary.DuplicateFileException
my code is
long companyId = serviceContext.getCompanyId();
File sampleChapter = (File) serviceContext.getAttribute("sampleChapter");
String folderName = "Sample_Chapters";
LMSUtil.createFolder(folderName, companyId);
String filePath = folderName+StringPool.SLASH+fileName;
System.out.println(filePath);
try {
DLStoreUtil.addFile(companyId, CompanyConstants.SYSTEM, filePath, sampleChapter);
} catch (PortalException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SystemException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
And the error I got is

All I need is versioning of documents uploaded. Please anyone help me in resolving the problem. Thanks in advance
Just from glancing at the API, you'll want to check if hasFile then updateFile else addFile
I'm performing a similar operation using a different API (DLAppServiceUtil) and given that the needed parameters are less when using DLStoreUtil, I'm going to investigate converting to this approach.
Edit: I'm not able to see the folders/directores in the Documents and Media portlet that are added through DLStoreUtil. I have verified they are uploading correctly into the /data/document_library directory. For my particular case I'll want to stick with DLAppServiceUtil due to the requirement that the files be managed via that portlet after being uploaded through my custom portlet.
See Also: How do I use the different file storage and retrieval APIs in Liferay?
When you are uploading the file at that time you should have to save the file with datetime so next time you are uploading same file it will not throw duplicate file exception.
You have to override the Document and Media Portlet and writing a code for saving the file you should have to mention datetime with file.
once you done then deploy the code on server.
Thanks & Regards,
Anil Kumar Shrivastava
I don't understand why I am getting this exception.
It seems to be related to JPA but there aren't any JPA annotation in XxxService or unable to find the class XxxService

You do not have the class file for XxxService in your classpath.
Add the jar file (with this class) to the classpath and the issue will be resolved.
I am new to GWT and my program was compiling fine until now when I am trying to add a calendar with round corners using rico.js. What doest this error mean and what should I be looking for?
This is also happening ONLY IN FIREFOX (I have 4.0.1)
[ERROR] Line 105: No source code is available for type com.packtpub.gwtbook.widgets.util.Rico; did you forget to inherit a required module?
Thank you

Is the external package rico.js wrapped in gwt or is it just plain js? If its a wrapper, see if you have included the module in your .gwt.xml file. If its plain js, see if you have added the script tag in the html file. If neither, then we will need to see the code
