Question

All in a sudden my Java application using SimpleDB doesn’t work anymore. I’m using Java AWS SDK version 1.2.4 on Windows 7. I’ve the following exception:

java.security.KeyStoreException: problem accessing trust storejava.io.IOException: Invalid keystore format
com.sun.net.ssl.internal.ssl.TrustManagerFactoryImpl.engineInit(TrustManagerFactoryImpl.java:55)

com.amazonaws.services.simpledb.AmazonSimpleDBClient.<init>(AmazonSimpleDBClient.java:118)

What could the cause be and how to solve the problem?

Answer 1

Sorry for self answer, but I solved the problem. It was caused by my certificate file, pointed by these statements loaded by a ServletContextListener defined in my web.xml

 String sslCertPath = contextEvent.getServletContext().getRealPath(
   "/WEB-INF/classes/jssecacerts");
 System.setProperty("javax.net.ssl.trustStore", sslCertPath);

Commenting out those lines everything works. This is caused by a corruption of that file.

After that, I fixed my key store, uncommented the lines, had a little fight with tomcat and after that everything was working again, also with my certificates in place.
