Eclipse Maven Issue : 'dependencies.dependency.version' for jar is missing

Having trouble building a new Maven Project in Eclipse. I get the following exception regarding missing dependencies, even though I have added the dependency for this jar in the parent pom with a version tag.

Child pom.xml:

  <dependencies>
            <dependency>
                <groupId>com.oracle.jars.common</groupId>
                <artifactId>javax.ejb_3.0.1</artifactId>
            </dependency>
                      ...
                      Other Dependencies
        </dependencies>

Parent pom.xml:

        <dependencies>
            <dependency>
                <groupId>com.oracle.jars.common</groupId>
                <artifactId>javax.ejb_3.0.1</artifactId>
                <version>11.1.1.4.0</version>
                <scope>compile</scope>
            </dependency>
           
            ...
            ...
            Other Dependencies
            ...
            ...
        </dependencies>


Error:

 The project testwebapp-parent:testapp:1.0-SNAPSHOT (C:\workspace\testwebapp-parent\testwebapp\pom.xml) has 2 errors
[ERROR]     'dependencies.dependency.version' for com.oracle.jars.common:javax.ejb_3.0.1:jar is missing. @ line 18, column 15
[ERROR]     'dependencies.dependency.version' for com.oracle.jars.common:javax.jms_1.1.1:jar is missing. @ line 22, column 15

If I run it with '-N'  option in Run Configurations as shown below it works fine, but it doesn't fix the problem when I run it on remote build environment like Hudson, or if I try to directly run it.



Solution :

The fix to the problem is having a <dependencyManagement> tag in your parent POM.
I just had <dependencies> tag in my parent pom. After adding this tag it works just fine.


Parent pom.xml:

    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>com.oracle.jars.common</groupId>
                <artifactId>javax.ejb_3.0.1</artifactId>
                <version>11.1.1.4.0</version>
                <scope>compile</scope>
            </dependency>
           
            ...
            ...
            Other Dependencies
            ...
            ...
        </dependencies>
    </dependencyManagement>

Apache Maven - Non-resolvable parent POM

Facing following exception while creating a new Maven Project.

My Parent POM file had some invalid open tags which caused build failure, After I removed those tags, I receive following exception:

[ERROR]     Non-resolvable parent POM: Failure to find testapp-parent:pom:1.0-SNAPSHOT in http://mavenrepo.test.com/content/groups/public/ was cached in the local repository, resolution will not be reattempted until the update interval of maven has elapsed or updates are forced and 'parent.relativePath' points at wrong local POM @ line 3, column 10 -> [Help 2]
[ERROR]  

Looks like to me that its still picking up the previous POM which had errors, probably because that was pushed to the local repository. Doing a clean install did not help me.

I looked into mt local repository for the file with .lastUpdated suffix,
testapp-parent-1.0-SNAPSHOT.pom.lastUpdated

I tried adding an empty tag <relativePath/> but it did not resolve the issue.
Also I deleted the project folder itself from my local repository, still din't help.

MongoDB Couldn't connect to [127.0.0.1] couldn't connect to server 127.0.0.1:27017

Getting following exception while trying to import the data into MongoDB from a CSV file on a remote linux box.

>mongoimport -d EmpDatabase -c EmployeeRecords --type csv --file /var/lib/testuser/root/data/emp-datasheet.csv --headerline

Couldn't connect to [127.0.0.1] couldn't connect to server 127.0.0.1:27017

Solution:

This requires the host and port to be specified with mongoimport command:

--host <hostname><:port>

Example:

>mongoimport --host <<HOST>>:<<PORT>> -d EmpDatabase -c EmployeeRecords --type csv --file /var/lib/testuser/root/data/emp-datasheet.csv --headerline

SFTP Command to transfer files remotely

I was looking for something similar to WinScp for MacBook Pro, but could not find it. There are similar tools available to do the same task but I did'nt want to install an unknown application.

Finally I had to resort to SFTP.

In the following example I am trying to connect to a remote Linux server from my local MacBook-Pro and upload some *.csv files from my local folder to a remote folder.

Steps:

• Connect to remote server

> sftp remote.secure-wb1-hvbd.com

Connecting to remote.secure-wb1-hvbd.com...
remote.secure-wb1-hvbd.com FTP server ready.
Name: yourusername
Password: 

//// Provide user and password for authentication

• Navigate to Remote Destination Directory

Connected to remote.secure-wb1-hvbd.com
sftp> cd /var/lib/users/test/destination-dir

• Use the lcd command to specify the local source directory where file to be uploaded, exists.

sftp> lcd /Users/localuser/workspace/server-data

• Use the put (single file), mput (multiple files) commands to upload the files to remote directory.

Example :
// Upload all *.csv files using mput command
sftp> mput *.csv

Or 
// Upload a specific file using put command
sftp> put testout.csv

•  Similarly get and mget can be used to retrieve the files.
• For larger files, we might encounter the following error [rite failed: Broken pipe]. Use the zip utility to  zip the file first and then do sftp. For Example:

//Zip the file on local server
>gzip testout.csv
 //It will create testout.csv.gz

// Upload on server using SFTP as mentioned above

//Unzip the file on remote server 
>gzip -d testout.csv.gz

[ERROR] The prefix "soap" for element "soap:binding" is not bound.

I encountered the following Exception while making WSDL changes for JAX RPC to JAXWS:

  line 368 of file:/C:/workspace2013/test-search-parent/test-search/src/main/wsdl/TesWebWSDL.wsdl

[ERROR] The prefix "soap" for element "soap:binding" is not bound.

Its a small fix. I forgot to add the required prefix in wsdl definitions. We need to add the "soap" prefix in WSDL definition tag as shown below:

&lt;wsdl:definitions name="TesWebWSDL" targetNamespace="http://www.testweburl.com/wsdl/TesWebServ" xmlns:xsd="http://www.w3.org/2001/XMLSchema"

xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:params="http://www.testweburl.com/TesWebServ/dataobj"&gt;

Apache Wicket - The object type is not Serializable

One of the common exceptions in Wicket is the Serialization exception as Wicket maintains the page maps and serializes and deserialize the page components along with components :

One of the solutions to the problem would be to either make the object in question "transient"
or make its class implement "Serializable" interace.

In this case the object of "TestDataServiceImpl" class needs to be declared with transient modifier
or its class should implement the Serializable interface.
